DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

[000581 Referring to Figures 1 through 26 of the drawings, it will be noted that Figures 1 through 24 illustrate a first preferred embodiment of the dispensing spout of the present invention, πnd Figures 25 and 2fj illustrate a second preferred embodiment of the dispensing spout of the present invention

[00059] Reference will now be made to the Figures 1 through 24, which show a preferred embodiment of the dispensing spout of the present invention, HS indicated by general reference numeral 20 (000601 In this first aspect of the present invention, there is a dispensing spout 500 mounuble to a liquid feeding means, such as a dispensing nozzle , hose, container, ur the like, to provide a delivery system Tor delivering liquid from a liquid source, such as a portable fuel container 10, or the like, through a hose, .suuh as a fuel hose, gurdcn hose, or the like '1'he dispensing spout 500 comprises a cnstng 120 having nn mlei 139 to teceive liquid from the lujuid source, such as the porLable fuel container 10, and a dispensing outlet 138, also refeired to a.s the trunk tip opening, to dispense liquid to a destination, either a permanent or portable container or leceptuole, or the like, such as a portable ftiel container, n fuel tank, and so on The inlet 139 und the dispensing outlet 138 are connected in fluid communication by a dispensing passageway 155

[0<H)61] There is an openable and closαble valve means HS indicated by the general reference numeral 101 , for permitting nnd precluding, respectively, the dispensing of liquid from the dispensing outlet 138 of the casing 110. The vnlve means 101 prefeinbly comprises a closure member 130 for closmg and opening the dispensing outlet 138, The closure member 130 is slidably retained with in the casing 120 for movement between its open position and its closed position The valve means 101 , specifically, the closure member 130, is biased closed by means of a coil spring, .specifically trunk spring 140, which is in compression The trunk spring 140, which is compressed in between the jet 150 and the closure member 130, provides d force that pushes the closuic member 130, towaids the trunk tip 125. The trunk tip 125 is tapered to channel the flow of liquid to the closure member 130.

[00062] Thy closure member 130 has an "O"-nng 131 seated in a cooperating annular gioove towards the front of the closui e member 130 When the closure member 130 is m its closed position, as hiased by the trunk spring 140, the "O"-iing 131 sents against the inner annular surface ot the tip of 125 of the casing 120, which is the dispensing outlet 138 of the easing 120. The dispensing opening 138 is scaled as the ibrce of the trunk spring 140 compi esses the "O"-πng 13 I between the closure membei 130 and the trunk lip 125 interior, thereby providing an airtight leak-pi oof seal (see Figures 4, 5, 19 und 24)

(00063) When tlic closure member HO is in its open position, the "O"-ring 13 I is separated in Space relation from the inner unnulur surface of the tip 125 of the casing 120, thus permitting liquid flow between the closure member 130 and the dispensing outlet 13»

|00064| The dispensing -spout 500 further comprises a slider assembly 200 mounted in sliding relnlion around ύie casing 120. The shdei assembly 200 is movable between a forward position, as can be best seen m figures 1 , 2Λ, 2B, 3, 4, 18 and 19, and a rearward position, as can be best seen in figures 20,21 and 22 The toward position and the rearward position of the slider assembly 200 corresponds to the closed position and the open position, iespectivcly, of the closure member 130 Accordingly, in order to open the valve means generally referred to by 101, the sbdcr assembly 200 is moved rcarwardly, in an indirect manner, as will Iw discussed in greater datail subsequently.

[00065] The dispensing spout 500 also comprises n receptacle engaging trigger means generally i ei^'en ed to by 301 operntively mounted on the casing 1 10. More specifically, the ieccptacle engaging trigger means 301 comprises n inggcr assembly 300 disposed in sliding relation on the slider assembly 200 The receptacle engaging trigger means 301 includes an upper hook 325 and a lower hook 328 for engaging the inlet πm of a container 10 Each of the upper hook 325 and the lower hook 328 is connected to, and preferably formed as an integrally molded part of tlwreccptacle engaging trigger means 301 (I'm thinking this is only the red purt)

[00066] I he receptacle engaging trigger means 301, and more specifically the trigger assembly 300, are movable along the casing 1 10 between a vaJvc-opcn position, as can be best seen in figurcs21, and a valve-closed position, as can be best seen in figures 19 'ITic trigger assembly 300 is biased to the forward valve-elosed position by means of a trigger return spring 330 mounted in substantially surrounding relation on a trigger spring guide shaft 321 that extends- reaiwardly fioni the upper hook 325, and also seats in a trigger spring guide 230 on the slider assembly 200

140 such that the "0"-πng 131 seats agonist the inner arunulni surface of the tip of 125 of the casing 120 Accordingly, lhc valve means 101 is closed In the valve-open posilion of the trigger assembly 300, the closure membei 130 is moved to its open position against the biasing of the trunk spring i40 such that the 'O"-iing 131 disposed ui space relnlion lrom the inner annular surface that defines the dispensing outlet 138, at the tip 125 of the casing 120 Accordingly, the vnlve means 101 is open, and liquid can flow through the casing 120 and out the dispensing outlet 138 [00068] The dispensing spout 500 according to the present invention further comprises lmknge means 3 15 operatively connecting the receptacle engaging trigger means 301 and the vπlve means 101 The linkage means generally referred by 315 has an enabled configuration, as can be beat seen in figures 18 and 20, and n disabled configuration, as can be best seen in figure 23 In iis enabled configurntion, the receptacle engaging trigger means 301 and the vnlve moans 101 are operatively connected such that movement of the receptacle engaging trigger means 301 from the valve-closed position to the valve-open position causes the valve means 101 to open More specifically, as can be best seen in figures I R and 20 the linkage means 315 transmits a rearwardly directed force Jroro the receptacle engaging trigger means 301 , specifically the upper hook 325 und the lower hook 328 and the trigger assembly 3IX⁾, to the linkage means 315, as will be discussed in greater detail subsequently.

100069] In the disabled configuration, the valve means 101 is closed such that fluid cannot be dispensed from the dispensing outlet of the casing 110 Further, the valve means 101 is precluded from being re-opened by movement of the receptacle engaging trigger means 301 until the linkage means 315 is reset to its enabled configuration

[000701 More specifically, the linkage means 315 comprises a first linkage member 340 and a second linkage memher 260 connected together in angularly variable i elation at a linkage elbow 750, so as together to be movable between the enabled configuration, as can be best seen in figures 18 and 20, and the disabled configuration as can be best seen in figure 23. The first linkage member 340 and the second linkage member 260 each have two parallel identical arms, for the sake of redundancy and strength

J00071] In the preferred embodiment, as illustrated, the first linkage member 340 and the second linkage member 260 connected logclbcr in pivoial relation at the linkage elbow 750. A "C"-shaped axis clasp 342 disposed at the back end of each of the arms of the first linkage member 340 receives and retains in pivotal relation a slider linkage axis shaft 262 disposed that the front end ufihc second linkage member 260.

[00072] The first linkage member 340 is operatively mounted on the receptacle engaging trigger means 301 and die second linkuge member 260 is operatively mounted on the slider assembly. Accordingly, the first linkage member 340 mny be ielerrcd to as the trigger linkage member and the second linkage member 260 may be referred to us the slider linkage member 260 The trigger linkage member 340 has a trigger linkage axis shaft 341 disposed at its front end, which is received and retained in pivoting relation within a trigger linkage axis shaft clasp 323 that is integrally formed on the trigger assembly 3(K).

[00073] The slider linkage member 260 has a "C "-shaped axis clasp 261 disposed at the back end of each of the arms of the silder linkage member 260, which is receives and retains in pivoting relation a slider linkage axis shaft 226 that is integrally formed on the slider assembly 2(X) When assembled together, the trigger linkage member 340 and the slider linkage member 2^ήO arc spring biased to the enabled configuration by means of a reed spring 343 connected to the trigger linkage member 340. Preferably, the reed spring 343 is integrally funned as part of the trigger linkage member 340.

|00074| The dispensing spout 500 further comprises a deactivation mean* 156 for changing the linkage means 315 from the enabled euπlϊguration to the disabled configuration The deactivation means 156 includes a venturi means 157 disposed within the casing 120. More specifically, the venture means comprises a venturi that is disposed at the tip 151 of the jet 150 As liquid leaves the jet lip 151. which is an integral part of the venturi, it will expand becoming turbulent. The expansion and the turbulence of the flow will cause the liquid to collect and mix with air and that air will exit the dispensing spout 500 with the liquid being dispensed through the dispensing outlet 138. The liquid flowing through the trunk body 120 will create a negative pressure within the trunk body 120 which will continually draws air into the trunk body 120 through airway 127 as the liquid is flowing. This negative pressure is the force which is used to change the linkage means 315 from its enabled configuration to its disabled configuration, as will be explained in greater detail subsequently

(((0075] The dcaclivalion menns 156 also comprises an air conduit 240 having ail αu inlet 241 at a Front end thereof and an πir outlet 227. 'Ihe air conduit 240 is in fluid communication with the dispensing passageway 155, to interact with the venturi means 157 More specifically, the air conduit 240 is in fluid communication with the dispensing passageway 155 via an air hole 228 in the slider assembly 200 and an expandable end retractable chamber 242 between the air conduit 240 and the air hole 22S The expandable ami retractable chamber 242 comprises a cylinder 220 and piston 221 moveable within the cylinder 220 The piston 221 engages the cylinder 220 in substantially sealed relation due to an "O"-ring 222. There i_. also a spring means, specifically a coil spring 223, to bias the piston 221 to an extended position. Pisloπ arms 224 extend laterally outwørdly from opposite sides ot the piston 221 , so as to be able to engage the linkage elbows 750 on each side of the linkage means 315 [00076] The air conduit 240 is in fluid communication with the dispensing passageway 155. as described above, io permit ihc drawing of air into the dispensing passageway 155 through the air inlei 241 when the air pressure is reduced by ihc ventuπ means 157, but inhibiting the flow of air into the dispensing passageway 155 when the liquid level of dispensed liquid reaches the air inlet 241 and blocks access, of an into ihe air inlet 241 When [he airllow into the dispensing passageway 155 is inhibited, the air pressure within the cylinder 220 produces a downward force on the piston 221 , thus lowering the piston 221 froiυ a raised position, as seen in figures 19, 20 and 21 , to a lowered position, as seen in figures 22 and 21 As the piston 221 moves downwardly, the piston arms 224 push on the trigger linkage member 340 and the slider linkage member 260 υf lhe linkage means 315 at the linkage elbow 750. The trigger linkage member 340 and the slider linkage member 260 go from their enabled configuration, past an over-the-center point, and essentially tall to their disabled configuration In this manner, ihc deactivation means 156 has caused the linkage means 315 Io change Io the disabled configuration, which in turn causes the valve means 101 to close, thus precluding the delivery of liquid from the dispensing outlet 138 of the casing 110

(000771 I" ^{a raorc} general sense, it can readily be seen thai the deactivation means 156 is foi changing the linkage means S 15 from the enabled configuration to the disabled configuration, in response to detecting the proximity of dispensed liquid in a receptacle, Iu thereby allow ihe valve means 101 u> close, thus precluding the delivery of liquid from the dispensing outlet 138 of the easing 1 1 Q.

[00078] There is also an indication means opernlively mounted on the casing 120 and comprising a diol indicator 420 with a display 421 as seen in the covers window 411 of the cover body 410 The dial indicator 420 is pivotally mounted within the interior A hub means with in the cover body 410 provides the dial indicator 420 with a pivot point 412 where the axis shalls 422 on the dial indicator πb 423 in located, When lhu dispensing .spout is in the closed setting, the dial indicator step follower 424 on the dial indicator rib 423 will be in contact with the dial indicator step 350 which in turn will orient the dial indicator 420 at an nngle dial aligns the closed test uπ the dial indicator display 421 with the covers window 411 so that it can be seen. Similarly, the Step follower 424, the dial indicator rib 423 and dial indicator step 350 react to the relative jKisilioning of lhu parts of the dispensing spout to indicate the deactivation and stall orientations as well

(00079] As. shown in the drawings, lhcie is a dispensing spout, generally referred to bv the numeral 500, mounlahlc to a liquid feeding means for delivering liquid from a container or a hose In Figure 2 and 4, the liquid feeding means is a nozzle 20 whereas in Figure 1, it is the threaded delivery neck 43 of a gas container 10.

(00080] Generally the dispensing spout comprises a delivery trunk body 120 formed with a dispensing passageway 155 leading to n dispensing opening 138 for delivery of the liquid. Within the delivery trunk body 120, a venturi means generally referred to by 157 exists to reduce the pressure within the dispensing passageway as liquid ilows thiough it dunπg use because, after flowing through the smaller passageway of the jet 150, the liquid flows through the larger passageway of the delivery trunk body 120. thereby reducing pressure. Briefly, the ventuπ means is coupled with a control means, which includes a deactivation means. The dc-iictivalion menus including an airwwy 127 with an air opening 241. The air uuπduil 127 is in uummunicalion with the dispensing passageway of the trunks body 120 to permit the drawing of air into the dispeasing passageway through the air opening when pressure is reduced as aforesaid during use. The air opening 241 is disposed on the dispensing spout to mark a threshold level whereby when liquid in the receptacle rises up to reach the level where the air opening exists, further au- flow into the dispensing passageway is thereby cut off. The deactivation means then responds to shut oft^' (stop) the dispensing opening. More particularly, the de-activation means has a closure member 130, which is caused to move in the direction of How within (he delivery trunk Ui shut oft' the dispensing opening upon when the air opening is blocked υlTirυm nir duiing use, due to the change in pressure. By having the closure member move to shutoiϊthe dispensing opening in the direction of flow, space is saved ¹O lhat the closure member can be easily disposed wilhiπ ihc spout This will be more piirliuulurly expluined by the detailed description of the preferred embodiment, which hereby follows.

[00081] Oeneially. the preferred embodiment is a dispensing spout which has three functional settings, namely 1) 'closed' where the dispensing spout is not inserted into Ihc opening of lhe receptacle and the delivery passHgeWay in the dispensing spυut is closed, 2) 'open or start' where the dispensing spout is mounted onto the receptacle and liquid can be delivered from the source, be it a delivery hose or a container, and 3) 'reset and closed' wherein the delivery spout is mounted onto the receptacle for delivery ol^" liquid but the control means is activated, by reason of die receptacle being filled to a threshold level on the spoul dispenser causing ihc dispensing spout to close off further liquid delivery,

[00082] Respecting these three settings, there is an indication mcana comprising a dial indicator 420 with a display 421 as seen b the covers window 411 of the cover body 4 IO The diul indicator 420 is pivotally mounted within Ihc interior. Λ hub means with in die cover body 410 provides the dial indicator 420 with a pivot point 412 where the axis shafts 422 on the dial indicator rib 423 is located. When the dispensing spout is in the closed selling, the dial indicβtor step follower 424 oti the dial indicator lib 423 will be in contact with the dial indicator step 350 which in turn will orient the dial indicator 420 at an angle that aligns the closed text on the dial indicator display 421 wiώ the covers window 41 1 so that it can be seen, Similarly, the step follower 424, the dial indicator rib 423 and dial indicator step 350 react to the relative positioning of the parts of the dispensing spout to indicate the de-aclivalion and start orientations as well.

[00083] As shown, in the drawings, the preferred embodiment illustrated is a dispensing spout that can be easily secured as a delivery system for a liquid sowce. whether it be a hose, a container or a nozzle using standard threading or other appropriate means. In Figures 1 and 2, there is shown the dispensing spout, generally referred to by the numeral 500 mounted to, respectively a standard-type gas container 10 and a gas delivery nozzle 20 with a fuel line 23. llic dispensing spout 500 is connected, in both cases, by threaded couplers, referred Io in the drawings as 43 and 22, respectively. As will be readily apparent, the coupling means is standard and its design will depend on the application and device to which the dispensing spout will be mounted. As well, although this specification is being described in conjunction with a gas delivery ntizzle 20 end a gas container 10, it could be mounted to any type of liquid source which is to be poured or delivered, be it a different type of delivery system such as a hose or tube, or a different type of liquid other than gas.

J00084] When thy dispensing spout 500, is in the closed position, liquid ftiel is prevented lrom flowing through it and out of the dispensing opening. The system is senled. It is the trunk body 120 which acts to seal the dispensing spoul. The trunk body 120 itself utilizes three openings, which arc unsealed or sealed to enable the functioning of the liquid delivery or non-delivery. One of these tliree openings is the tiiink bases opening 139, another of these three openings is trunk tips opening 138 and the third of these three openings is the trunk bodies airway 127 located on the side of the trunk body 120.

[00085] The trunk bases opening 139 is scaled from the atmosphere by the screw uap 190, which is threaded on to the coupling means of the liquid source, be it a nozzle or gas container or otherwise. The screw cap 190 sandwiches the trunk base 126 and lhe jet base 1S2, as the ease may be in the drawings, against either lhe nozzle coupler's leading edge 25 or the gas container's inlet rim 42 providing an airtight leakproof seal I) tor the nozzle: as between the nozzle coupler 22, jet I SO and trunk base 126; or II) for the gas container, the ga-s container coupling means 43, jet 150 and trunk base 126

[00086] The trunk tips opening 138 is scaled when the trunk core 130 is urged against Lhe interior of opening 13R (see Figures 19 & 24), The trunk core 130, during the operation of the dispensing spout 500, is en used to slide axially within the interior to the trunk body 120, to move between a sealed position (as is the case in the slop and de-activation settings) whore ii is seated against the interior of opening 138 (see Figures 19 & 24) and an open position (as in the ease where open setting) where it if unseated away from lht rim of the opening 138 (see Figure 21). As should be apparent, there is no tlowthroiigh of liquid from the source when the trunk tips opening 138 is sealed. In the preferred embodiment, the Tiiinks tip 125 is tapered at its forward end to cause increased constriction of the rim of the irunk tips opening 138 against the front end of the trunk core 130 as the normal biasing force of the spring 140 asserts itself, there being a trunk cores υ-riηg 131 which secures the seal as airtight πnd leakproof. The trunk lips opening 138 is the operative opening, which must be shut or opened to prevent or permit (low as the case may be, Lf the trunk tips opening 138 is open, liquid How is possible. If the trunk tips opening 138 is closed, no flow is possible.

[00087] The trunk bodies airway 127 is to be understood functionally with the air passageways which surround its two ends. This airway 127 functionally provides a passageway for air into the trunk hody to merge with liquid passing through lhe venturi 157 see figures 19,21 and -M as it is being dispensed through the dispensing spout 500.

[00088] But when air supply can no longer be drawn through the trunk bodies airway, such as would be the case if the level of liquid fill in the receptacle reaches the threshold level of air channel inlet 241 of the sectioned slider 210 (as will be described Inter), an increased vacuum pressure situation occurs within the dispensing spout to cause the trunks core 130 to reseat against the interior of the opening 138 to shut oil' the dispensation of liquid. This will be described in further detail later.

J00089] Suffice it to disclose at this portion of the description, however, that there is a chamber created as between o-ring 111 and o-ring 122 existing between the exterior of trunk bodies 120 and the interior of the slider body 2HO, The slider body 280 has an cylinders bottom air hole 228 which fluidly communicates through the chamber of the piston cylinder 220 with the cylinders air inlet 227. Cylinders air inlet 227 opens into air channel 240 which extends to air channel inlet 241. During use, however, as will be described later, nir is drawn into the chamber of the π-unk body 120 in the opposite direction of the fluid flow, meaning that air enters the system through ntr inlet 241. tiavels through ntr channel 2-40 and air inlet 227 jπd then through the chambci nt the piston cylinder 220 \o exit thuxigh air hole 228, Lhen through the chanibei defined by the o-imgs 121 and 122 and into the trunk body 120 through opening 127

[00090 J When opening the dispensing spout 500, the tip 201 should be placed mside a gas receptacle inlet 41 where either the triggers upper hook 325 or the ti iggors lower hook 328 is rested on the gas contiunei inlet nm 42 (see Figure i 6) Once in place and properly aligned, the user will either apply pressure down the length of (he nozzle 20 or press down on the gπs container 10 with a loree along the ueniei lme of the auto closure auto shut off spout 500 This force will be u ansferred to the tngger bodies hooks (325 & 128, depending on lhc Figure) which are integrally molded into the trigger body 320 ITie spouts trigger assembly 100 will then convey that force to the spouts slider assembly 200 via the connecting linkages causing the .spouts slider assembly 20« to slide tiMally along the spouts trunk assembly 100 towards the trunks base 126 (See the change in position _HS between figures 19 and 21 ) ITie force transferred to the spouts slider assembly 200 by the spout* logger asscmhly 300 will have been further transferred to the trunks core 130 via the trunk cores lip ridge 133 which is in contact with the exit grate 250 of the slider bodies 2X0 (See Figures. 19, 21 and 24) Hint force, in turn, will transits thiough the trunks core 110 Io compress the trunks spring 140, which was also being compressed as the bunks core 130 slid along the interior of the trunk body 120, corresponding to movement of the spouts slider assembly 200 (see comparison ol'Figuies 19 and 21) Resulting from this, the spouts slider assembly 200 will he moved to unseat the trunks cores o πng 111 of the trunks tip 125 lrom the rim area of the opening Liquid ΪS allowed to llow from the source thiough the iet 150, down the length of the trunk body 120 around the trunks core 110. out the trunks tip 12S, into the mteiior of the slider body 280 and past the esit grate 250 out of the dispensuig spout

[000911 As the dispensing spout 500 was changed to the open position, the display 421 of the dul indicator 420 was moved rrani indicating "closed" to "open" as appeals in the LOVCIS wuidow 41 1 so that the dial indicators step follower 424 on the dial indicntofs πb 421 iests on the trunks dial uidicatυi step 124 (see Figiue 22). More particularly describing the movement from the closed position Lo the open position, as the spoub, trigger assembly 100 and the spouts slider assembly 200 weie moved dxially along the spouts trunk assembly 100 towaids the trunks base 126, the spouts cover assembly 400 (attached to Lhe spouts Iπggei assembly 300) nlso was cumud As all three of these assemblies 200. 300 and 4(X) moved together, the dml indicators step followei 424 came into contaul with the trunks dial indicator step 124 In result, the dial indicator step follower 424 will have then ridden iψ onto the trunks dial indicator step 124, rotating the dial indicator 420 clockwise abuul the dinl indicators pivot point 412 So it is thnt the center area of the dial indicator display 421 , which i eads 'st jrt' thereupon appeal s m the covers window 411 to be seen by the uset

[00092] The design oi the dispensing spout 500 takes advantage of the fluid dynamics witliui the spouts trunk, assembly 100, wtw-h has been configured Ui utilize veoturi principles As llii. liquid leaves the jets tip 151 , it will expand becoming turbulent Hie expansion and the turbulence of the liquid flow will cause the liquid to Lollcct and nax with air (entering the system through air inlet opening 241 and following the route previously desciibed) within the trunk body 120 so thnt lhe air will exit the dispensing spout with the liquid As the dispensing spout was oriented into the 'open' position, the airway was opened up between the eMcπor of the dispensing spout and the interior of the trunk body 120 to allow airflow directly into lhc trunk body 120 Moving into the Open' position from the 'closed' position, the spouts slider assembly 200 moved along the trunk body and the hole tn the bottom of the piston cylinder 228 eieaicd an airway into the trunk bodies 120 This alignment enables the air U) entering the spouts an inlet opening 241 , flowing down the sliders air channel 240, into the pistons eylindei 220, down through the cylinders bottom _uτ hole 228, mto the cavity between lhe trunks lower o-ππgs 228, and then tlirough the trunk bodies airway 127 into the trunk hodies 120 interior (see I'lgure 21 ) The air introduced into the trunk body will enter behind the _jets tip 151 into the _jets, air cavity 154 wheie this configuration helps prevent liquid from going directly mto the trunk bodies airway 127 Utilizing ventuπ principles, the liquid flowing thiough the trunk body ] 20 cientes a negative pressure within the trunk body 120, nnd it is this negative pressure which continually diaws air into lhc trunk body 120 as the liquid is flowing

[00093] To turn off the flow ol the dispensing spout and ieturn the indicator to lhc 'close' position, the user need only lemove the spouts tip 201 fi om the opening ol the gas ieceptacle 40 (see Hgurc 16) Doing tins lenioves lhc forte jiserted against the triggers lower hook, allowing the trunk spring 140 to reassert its normal VA Jsed position to ietuin the trunk uiru 110 to the closed orientation (sec Figuie 19) Returning to that position, the force of the trunk spring will press the trunk core 130 m the area of the trunk cores ø-πng H l against the ulterior ol the opening HS, iesultmg m a leak-proof seal It will be apparent lhut the trunk core 1¹M) JCLS as a valve means

[000!M[ In the preJerrcd embodiment, the trunks body 130 moves along the axis of the direction ol" flow nnd this creates an economv of space, allowing the spout to be made of an more compact dimension than if the valve menns liad to move perpendicular to the axis of the direction of flow. There are advantages achieved by tins preferred configuration, but it is also possible to achieve closing by crcalvmg n valve means that closes the dispensing opening by moving in a direction perpendicular or different to the axis of the direction of flow

|000!>5| However, it will also be desired that lhc user will be able to rely upon this dispensing spout to automatically jJiul off the flow of liquid upon the gns receptacle 40 reaching a filled up capacity. This automatic shulofTiw what can be termed as the deactivation condition position In this regard, the filled up capacity would be reached upon the level of the liquid deposited in the ieceptacle 40 reaching a threshold marking on the dispensing spout, namely where the channel inlet 241 is dispos_>ed. This is where no flirther air can be drawn into the flow syxicm and the pressure of the system will be allured causing a mechanical reaction of the parts which will automatically shut olϊthe flow of liquid or deactivate the spout (sec figure 2? and 24)

[00096] As the air channels inlet tip 241 is covered by lhc rising liquid in the gas receptacle 40, air would no longer be able to enter the aii channels inlet tip 241 and that would create a decrease in pressure within the interior air passageways and cavities, namely the air ehannel240, piston cycler 220, the cavity between the trunks lower o-rings 128. and trunk body 120. Λs this decrease in pressure continues, the piston 221 will be drawn down (see Figure 22 and 23) The downward motion of the piston 221 will in turn act on ihe slider linkage 260 and lhc trigger linkage 340 via the piston amis 224, whieh will be pushing the linkage elbow 750 downwardly (see Figure 22).

100097} As previously described, lhc force applied to the spouts trigger assembly 300 needed to open the dispensing spout was conveyed through the trigger linkage 340 and was transferred io the spouts slider assembly 200 via the slider hnklage 260 causing the spouts trigger assembly 300 and the spouts slider assembly 200 to move together as they slid axially along the spouts trunk assembly 100 toward* the trunks base 126. The auto shutc-ff feature of the preferred embodiment works by relieving the spouts slider assembly 200 of the force being transferred to it by the spouts trigger assembly 300 As the liquid in the gas receptacle 40 reaches the threshold level, it will cover the air channels inlet tip 241 causing the vacuum pressure in the nir conduit Io increase which will pull the piston 221 down disengaging the rigid connection between the spouls trigger ussembly 300 and the spouts slider assembly 200 (see Figure 23).

J0Θ098] 'lTic piston aπns 224 extending lbπn lhc side of the piston 221 will push down on the linkage elbow 750 which will rotaie the trigger linkage 340 clockwise about trigger linkage axis 341 nnd rotating slider linkage 260 counter clockwise about slider linkage axis shall 226 until the force conveyed between lhc linkages 340 and 260 is relieved (see Figure 23) In the present invention, the tπgger linkage 340 will have rotated clockwise iihout trigger Linkage axis 341 to be pointing below the horizontal and the slider linkage 260 will have rotated counter clockwise about slider linkage UKIS shall 226 to be then directed downwardly (see I'igure 23).

[00099] The disengagement of the πdged connection between the linkages 340 and 260 permits the trunk spring to reassert to Jt* normal biased disposition and push the spouts slider assembly 200 to its closed position, scaling the dispensing opening at the trunk tips 138. In contrast, the spouts tπgger assembly 300 remains in place (sec figure 23 and 24) As weli, fis the spouls slider assembly 200 slides axially along the trunk body 120 towards its closed position, the piston cylinders bottom air hole 228 will move out of communication with the cavity between the trunks lower o-iings 128 to interrupt the airway created when the auto shut off spout had been opened Λs the de-aeti valion disposition is occurring, the piston cylinders bottom air hole 228 will move axially along the trunk body 120 I mm the cavity between the trunks lower o-rings 128 to the cavity between the trunks upper o-πngs 129 The cavity between the trunks upper o-πngs 129 is formed by the trunks o-rιng at the tip 123 and the imnks middle o-ling 122, which are sandwiched inbclwccn the trunk bodies 120 exterior ond Ihe slider bodies 280 interior

[OOUIOO] As the How oi^' liquid stops, the ventuπ vacuum pressure produced by Uw flowing liquid will also stop, creating an absence of the decreased pressure thai had drawn the piston 221 downwardly. When this decreasing pressure effect is lost, the spring 223 will reassert its shape and push the piston upwardly within the pjston cylinder 220 until the top of the piston arms 224 come into contact with the piston retention hooks 225 'l hc ietention hooks 225 ietain the piston 221 in its position within the piston cylinder 220.

[000101] In the preferred embodiment, when the dispensing spout is m the closed position, the linkage elbow

750 of the tπgger linkage 340 and the slider linkage 260 is slightly hyper-extended upwardly so that force experienced by the trigger linkage ¹UO and the force experienced by the slider linkage 260 are not in the same plane The angle between the trigger linkage 340 and the slider link«s^e 2GO force directions would be greater than 180 degrees on the top side of these two components and less than 180 degrees on the bottom side ol these components 1000102] The hyper-extended stale, Q$ described, would transfer a portion of the compression forces experienced by these linkages 340 and 260 upwtudly onto the pision arms 224 ihe slider linkage stop 229, thereby keeping the components 340 and 260 in a static state The provision of hyperextension in these linkages 340 nnd 260 provides for greater stability to the linkages 340 and 260 to prevent an accidental tripping into the de-activation position when the spout is in use. Alternatively, however, the linkage elbow 750 could be a straight 180 degree connection between the trigger linkage 540 and the slider linkage 260, relying on a spring such as the trigger linkages eantilevered reed spring 343, whieh would then provide the tame upwardly stabilizing force to prevent occidental tripping.

[000103] The dinl indicator will accordingly change from the 'open' selling to the reset selling indicating that the auto-shutoff condition, has occurred. Λs the auto eJosure auto shut off spout 500 is tripped by the pision 221 into the de-aciivation orientation the spouts slider assembly, 2(X)₁ will slide relative to the spouts trunk assembly. 100, and spouts trigger assembly 300, which will remain, relatively stationary. Before the auto closure auto shut otV spout 500 is tripped into the de-activation orientation, the auto closure auto shut off spoul is in the open or stnrt orientation and the dinl indicator .step follower 424 is resting on the trunks dial indicator step 124 (sec Figure 22) Λs tlie auto closure auto shut off spout is iπpped into the de-πctivation orientation, the sliders dial indicator step 270, which is positioned above the trunks dial indicator step 124 will slide under the dial indicator step .follower 424 (see Figure 23) This will cause the dial indicator 420 to rotate clockwise about the dial indicators pivot point 412 Io display the reset text of the dial indicators display 421 in the covers window 41 1 (sec Figure 23).

(0001041 After the 'deactivation' condition has resulted from fill-up, Lhe dispensing spout can be reset to its original 'closed' setting for further uso, by simple removal of the dispensing spout from engogemcnt with the receptacle. Upon disengagement, the tπgger return spring 330 will push the spouts trigger assembly 300, towards the sliders tip 201 reluming the spouts trigger assembly 300 lhe original closed position. As the spouLs (rigger assembly 300 is being reset into lhc closed orientation lhe trigger linkage 340 and the Slider linkage 260 wili also be maneuvered back into their original closed orientation, As the spouts triggei assembly, 300, moves towards the sliders tip 201 , the distance between the slider linkage axis shall 226 and the tπgger linkages axis shaft clasp 323 will increase causing the linkages 340 and 260 between them Ui straighten out 1 he increasing distance will rotate the trigger linkage 340 counter clockwise about trigger linkage axis 341 and rυlatmg slider linkage 260 clockwise aboul slider linkage axis shaft 226 until the linkages 340 and 260 of the auto closure auto shui oft' spout are back Io their original closed orientation (reference linkage (340 & 260) changes between Fig. 23 and 18),

fOOOlOSj In the preferred embodiment shown, it will be noted that the trigger linkages eantilevered reed springs

343 (see Hg 18, 20,22 and 23) within linkage members 340 help return, orient and maintain the positioning of the tπgger linkage 340 and slider linkage 260 when the nuto closure atilo shut off spoul is in the closed orientation. The Trigger linkages cnntilevered reed springs 343 provide a counter clockwise moment to the Trigger linkage 340, which would act to hold the linkage elbow 750 in place up against the underside of the piston arms (see Fig 18, 20,22 and 23)

[000106] It will be apparent that numerous modifications to the preferred embodiment are posithlc without deviating from the scope of the invention

10001071 For instance, piston 221 discussed above could also be a flexible diaphragm, as *hown in Figure 25

& 26 such as a bellow 290 with arms 292 & o-ring 291 , which could be press fit into the cylinder 220, that has a step 293 at the bottom io properly maintain its position within the cylinder 220 (see Fig. 25) M the vacuum pressure wilhiπ the spout increases, the flexible material of the bellows 290 is deformed tike an accordion drawing lhc bellows piston arms 292 down so they can perform the same function as the pistons amis 224 to trip the linkage at the elbow and close the valve The resilient mnterial of the bellows 290 would nlso act us its own rclum spring.

[000108] Of consideration, as well, lhe style of jet 150, as shown in the preferred embodiment, is compatible with all flowing fluids but an alternate jet 170 is prelerαble mid advisable when Lhe auto closure auto shuioff spoul of tilts invention is to be used with α container 10 thai only has one opening, Such an alternative jet is. shown in Figures. 26 When transfer! ing fluid from any container there must be and exchange of air for the fluid, which is removed. To transfer fluid from s container with only one opening, air can only be introduced into the container through the same opening that the fluid is exiting Alternate jet 170. 8fi illustrated in Figures 26, provides an airway that bypasses the fluid flowing out of the spout allowing air into the container, which will support a steady smooth transfer of the fluid fiom the contiiinei . The alternate jet 170 can be made to be compatible with both the nozzle 20 and any standard gas receptacle 10 For the gas receptacles 10 with only ϋoe opening as the spout JS opened up liquid within the container will begin to flow out through the spout. This liquid flow will also produce an airflow into the jets air cnvity 154 via the vcnluri effect. WiIh lhc alternate jet 170 ail" in the jets air cavity 154 will also he allowed k> flow into (lie container IO via the air channels in the jets threads 172 The air channels in the jets threads 172 provides an airway that bypasses the fluid flow making for a .smooth transfer υfbolh air and fluid in and out of the container.

[000109] Briefly, the dispensing spout of this invention is the combination o!^" a spout with auto closure and nuto-shutoff capabilities.

[(MM) 11 OJ Tlie outo auto-closure feature of the spout relate to a fluid flow control means such as a valve within the spout which functions to activate or start the flow of fluid through the spoul when the spout is properly mounted to lhc lill opening of a receptacle and will stop the flow of fluid when the spout is pulled a way or dismounts the receptncie. This feature of the present invention will be discussed in detail below

[(M)OJ U] The αuto-shutoff feature of the present invention relates to a deactivation means within the spout, which provides the dispensing spouts with the ability to automatically shutoff Lhc ilow of lluid passing through it upon Lhc receiving receptacle becoming Hill to the point where the fluid within the receptacle rises to cover and block the tip of the spout. This type aulo-shulυif function is well known in the ait but until this point on auto shutoff means has never been incorporated into a dispensing spout in the way that's disclosed in this invention.

|(M)0112j The auto closure auto shut oil spout of this invention has three settings or orientations that define its ftmction; 1 ) closed, 2) open or si art and 3) reset and closed

|0()0113| The first setling of lhis auto closure auto shut olT spout is iLs closed orientation defined by the requirement that liquid, vapor and or an- cannot leak out or in through the spout which would be attached any liquid source, liquid feeding means or fuel transfer system.

[000114J When The dispensing spout of this invention is applied to a particular liquid source it is the delivery trunk body or Trunk body ( 120) nlso known ns casing, which acts to seal that system. 'ITic Trunk body (120) itself lias three necessfliy openings in it, which are opened and closed to enable tile Λuto closure unto shutolT spout of this invention to function as disclosed below. The first of the three openings is the Trunk bases opening (139) the second is the Trunk tips opening (138) (see Fig 21), which is also the trunks dispensing opening and the third is the Trunk bodies airway (127) in the side of the Trunk body (120) (see Fig. 4, 5. 6. 8. 19).

|000115| When in the closed (500) orientation The first opening, the Trunk bases opening (139) is sealed by the Scicw cap (190) which is threaded onto the coupling means of either a nozzle or gas container (22 or 43) where the Screw cap ( 190) sandwiches the Trunk base (126) and the Jet base (152) up against either a nozzle Couplers lending edge (25) (see Fig. 4, 19. 21, 24) or a gas containers inlet nm (42) (see Hg, 16) providing an airtight leak proof seal between the Nozzle coupler (22), Jet ( 150) and T ruπk base ( 126) ur alternatively a Gas container coupling means (43). .let ( 150) and Trunk base (126) (see Fig. 1. 2, 3, 4, 16, 17, 19, 21, 24).

[ϋ(M>116| The second opening in the Trunk body (120) is the Trunk tips opening (138) (see Fig. 21) and is sealed by the Trunk core (130). which is free to slide axially along the interior of the Trunk body (120). It will be apparent that the trunk core acts as the valve means lor controlling the flow of liquid through the spout. When the Λuto closure auto shut off spout is in the closed orientation (500) the Trunks spring (140). which is compressed m between the Jet ( 150) and the Trunks core (130), provides H three lhat pushes the Trunk core (130) towards the Trunks tip (125). The Trunks tip (125) is tapered to constrict Oil the end and lhc Trunk tips Opening ( 138) is sealed as lhe force nflbe spring sandwiches the Trunk cores o-ring (M l ) m between the Tmnk core ( 130) and the 11 uπk tijis ( 125) interior providing an airtight leak proof seal (see Fig 4, 5, 6, 8, 19)

[000117] The third opening in the Trunk body ( 120) is sealed by the Cavity created between the trunks lower o-πngs (12S). lhc lnink bodies airway (127) facilitates the spouLs auto shulυff function and when the Auto closure auto shut off spout is in the closed orientation (500) the Trunk bodies airway (127) is unable to communicate or convey any material in or out of the mito closure auto shut off spout (500) because it is contained by an airtight leak proof Cavity between the trunks lower o-rings (128) that's created by the Trunks o-ring at the base (121) nnd the Trunks middle o-πng (122) which arc sandwiched in between the Trunk bodies ( 120) exterior and the Slider bodies (280) interioi (see Figuie 19). 1000118] When the Aulo closure αuto shut oil¹ spout of this invention is in its closed orientation the Trunk bodies (120) lhiee openings, Trunk basts opening 339), the Trunk lips opening (138) and the Trunk bodies airway (127) arc completely sealed

[0001 IVJ I he spout of this invention will indicate this dosed or waled oπentnlion wilh πn indication meaa_ where in the preferred embodiment it is Dial indicntoi (420) whose display (421 ) will be seen in the Covers window (41 1) (see Fig 2, 14, I S, 16. 17, 18, 20, 22, 23) The Cover body (410) is provided with o Dial indicator (420) pivotally mounted to its interior Λ hub feature on interior of the Cover body (410) provides the Dial indicator (420) with a pivot point (412) where axis shalls (422) on the Dial indicators nb (423) is located (see Fig 14, 1 5)

{0001201 When the Auto closure auto shut off spout is in the dosed onentntion (S(K)) the Dial indicators step follower (424) on the Dial indicators rib (423) will be m contact with the Triggers dial indicator Mep (350) which will orient the Dial indicator (420) at an angle that aligns the elo-cd text on the l>ial indicator display (421) wilh the Covers, window (41 1) so it can be seen (sec Fig. 18)

(0001211 The second uricπtuhon of this αuto closure auto shut off spout is its open or start orientation which allows fuel to flow freely through the spout

[000122] When opening or activating the auto shut oft spoilt (500) Lhe tip (201) should be placed inside a receptacle opening or container inlet (41 ) where either the Triggers upper hook (125) or the Trigger*, lower hook (S28) of the receptacle engaging trigger means is rested on the container inlet πm (42) (sec Fig 16), Once in place and properly aligned the usei will either apply pi ensure down the length of the Gas station shaped nozzle (20) oi piess down on the Gas container (10) with a force along the center line of the auto closure auto shut olT spout (500) This force will he transferred to the Trigger bodies h«^χ>ks (125 or 328) which πre integrally molded into the rπggei body (320) The Spout- Lπgger assembly (W) will then convey th_.l lorce to the Spouts slider assembly (200) via a linkage means, which is ui the enabled configuration 1 he linkage means u>ruiectine the Trigger body (320) and slider assembly (200) will cause the Spouts slider assembly (200) to slide axially along the Spouts trunk assembly (100) towards the Trunks base (126) (see the change in position of assemblies 100 &. 200 between t ig 18 & 20) The force trαnsteπed to the Spouts shdev assembly (200) by lhe Spouts trigger assembly ("500) will have been further transreπed to the iYunks Core ( 130) via the Trunk coies tip ridge ( 133) which is m contact with the Slider bodies (280) a vil grate (250) (see h ig 21 ) and that force will have been transferred thi ough the- Trunks core ( ] 30) to the Trunks spring ( 140), which will have become further compressed as- lhe Trunks core ( 130) slid along the interior of the Tmnk body ( 120) with the movement of the Spouts slider assembly (200) (sec component changes between Kig [9 & 21 ) '1Tn: movement of the Spouts slider assembly (200) will have unseat the Trunk coies o-ring (I T 1 ) unsealing lhe Trunks tip (125) Io allow fluid to flow through the Jet (150), down the length of the I runk body (120) around [he Trunks core (1 30), out the Trunks Up (125), into the interior ofthe blidcr body (280) and pasi the

grate (250) out of the apout (see Fig 21).

[(MIO 123] This open oi start onentatioπ is indicated by the Dial indicator (420) whose display (421), can be been ui the Covers window (41 1) (nee Fig 14, 20, 22)

[000124] Wlmn Lhc Λulo closure auto shut off spout is in the open oπeiiution Lhe Dinl indicator step iollowei

(424) on the DuI indicators nb (423) will be resting on the Ti uiikn di JI indicator step ( 124) (sec Hg 20)

[000125] Λh the Spouts T rigger assembly (100) and Spouts slider assembly (2⁽X⁾) were moved a\iallγ alunyi lhe Spouts, trunk assembly (100) towards lhc Trunks base ( i 26) the Spouts, cover assembly (400), which is attached to the Spouts Ii igger assembly (300) was earned along with them, As all thi ee υf these dsscmhhes (200, 300, & 400) moved together, the Dial indicators step follower (424) will have come in contact with the ¹I ranks dial indicαtoi step (124) The DwI indicators step follower (424) will have then ridden up onto the I ranks dial indicatoi step (124), whioh will rotate the Dial indicator (420) eloukwπe about the DmI indicators pivot point (412) _-o thai the center area ofthe Dial indicator display (421) which leads start will appear in the Covers window (A 1 1 ) so it can be seen (sec Fig 20)

1000126] To close or turn the spout off the opei aior will jusi simply take the nozzle away lrorn the Gas container (40) (see Hg 16) Al which point the force thai was applied to the Λuto closure auto shut olVspoul (500) to open it will hnvc been removed and the Trunk spring (140) will return the Trunk core (HO) back into its closed orientation (see Hg 17, 18, 19) where the foice uf the spring will sandwiches the Trunk cores o-ring (131) in between the Tiiuik coic (130) and the Trunk tips (125) interior to provide and airtight leak proof $.eal (bee Fiji 19) [000127] The auto closure feature automatically returns all the spouts components to their closed airtight !cak proof orientation ns tlie spout is token out of use

[000128J ltie third orientation of this auto closure auto shut oil^" spout is its reset and clo_cd orientation ilus is where the operator will have opened or started the spout but the spouts auto shut off feature has been activated, which has sealed the spout closed cutting off the flow or fluid exiting the spout.

l<⁾00129] The function of this inventions auto shut off feature is similar to that of a standard gπs station nozzle in that the auto shut off mechanism is triggered as the fluid level in the Cms container (40) rises to cover the tip of the spout and lhis feature enables the spout u> detect the proximity of dispensed liquid m the r eceptucje.

[000130] The design of the auto closure auto shut off spout of the present invention takes ndvontage of the fluid dynamics within the Spouts lnmk assembly ( 1 UO), which has been configured to ci caic a vcnturi {tax Fig. 3, 4, 5, 6, 7, 19. 21, 24) As the fluid leaves the Jets tip (151) it will expand becoming turbulent T he expansion and turbulence of the fluid flow will cause the fluid to pick up and mix with air within the Trunk body (120) and thill air will be token with the fluid flow as it exits the spoilt.

1000131 | The fluid flowing through the Trunk body ( 120) will create a negative pressure within the Trunk body

( 120), which will continually want to draw on air as the fluid is flowing and to facilitate this desired airflow, an airway from the exterior of the spoui into the interior of the Trunk body ( 120) has been provided (sec Fig. 21 )

f<M)0132] Λs the Auto closure auto shut oft^' spout had been actuated into the open orientation (reference section

0029-1) an on way was also opened up between the exterior of the spout and the interior of the Tnmk body (120) (sec Fig. 21) to allow airflow directly into the Trunk body ( 120). As the Spouts slider assembly (200) moved along the Trunk body ( 120) the hole in the bottom of the Piston cylinder (228) (see Fig 11) became aligned with the Cavity between the trunks lower o-rings (128) (see Fig. 19, 21 , 24) creating an airway into the Trunk bodies (120) interior (see Fig. 21 ) ITiis alignment forms ail air conduit that now allows air to enter the spouts nir opening or Λir inlet tip (241 ) How down the sliders Λlf channel (240) into the Pistons cylinder (220), down through the Cylinders bottom air Viola (22S). into the Cavity between the trunks lowei o-rmgs ( 128) and then through the Trunk bodies aii-way ( 127) into the Trunk bodies ( 120) interior (see Fig. 21 ) The air introduced into the trunk body will enter behind thø Jets tip ( 151 ) into the Jets air cavity (154) where this configuration helps prevent fluid from going Uiiectly into the Trunk bodies airway (127) The fluid flowing though Hie trunk body (120) will exit the Jets tip (151) where the venturiea turbulence will draw on the air inside the Jets uir cavity (154) through the gap, which is between the Jets lip (153) und the Trunk bodies ( 120) interior

10(HH 33] If at this point the operator would like to stop tϊlhng before the auto shutoff function is activated the operator would again just .simply lake the nozzle away from the Gas container (40) (see J-'ig. 16) to stop the flow The Trunk lips opening ( 138) would be automatically repealed by the auto closure function nπd as well, the airway that had been opened up between (he exterior and the interior of the spout would be interrupted as die Cylinders bottom air hole is moved out of alignment with the Cavity between the trunks lowei o-πiigs ( 128) (see Fig 19).

[000134] ^'I he fluto closure featuic will have automatieally returned all the spouts components to tbcii closed airtight leak proof orientation as the spout is taken out of use

|0(HH35] If the operator COMIΠUCK filling, the mito shutoff feature of this invention would be activated as the fluid level in the Gas container (40) reached the Air channels inlet tip (241 ). Au tlie Air channels inlet tip (241 ) is covered by the πsing fluid in the Cas container (40), air would no longer be able to enter the Air channels inlet tip (241 ) arid that would cause the negative vacuum pressure within the Air channel (240), Pistons cylinder (220), Cavity between the trunks lower o-rings (128), and Trunk bodies ( 120) interior to increase. Λs this vacuum pressure builds up within this system it will get to a pomt where that pressure will begin to act on the spoutsa pressure responsive means within the r<poul where in the preferred embodiment it is a piston means where (hat Piston (221 ) will be drawn down (see t ig 22) so that this downward motion of the Pistons (221 ) will in turn act on the Slider linkage (260) which also known as the second linkage and the Trigger linkage (340), which also known a^ the first linkage via the Piston arms (224), which will be pushing the Linkage elbow (750) down (sue Fig. 22). [OtH⁾ 136| The force applied to the SpouLs Logger assembly (300) needed to open the spout had been conveyed through the Trigger linkage (340) and v/aa transferred to the Spouts slider assembly (200) via the slider linkage (260) causing the Spouts tπggei assembly (300) and the Spouts slider assembly (200) to move togethei (is they slid axially along the Spouts trunk assembly (100) towards the Trunks base (12f>) The auto ^hutoff feature of tins invention works by relieving the Spouts slider assembly (200) of the force being transferi ed to it by the Spouts trigger assembly (300) As the fluid m (he Gas container (40) reaches the top it wil! cover the Au channels inlet tip (241) causing the vacuum pressure in the wrway to increase which will pull the Piston (221) down disengaging the rigid connection between the Spouts trigger assembly (300) and the Spouts slider assembly (200) (see Fig 23)

[000137] The Piston arms (224) extending fiom the side of the Piston (221) wili push down on the Linkage elbow (750) whieh will rotHle the Trigger linkage (340) clockwise about Trigger linkage HXIS (341) and rotating Slider linknge (260) eouπtcr clockwise about Slider linkage axis shall (226) till the point where the foice being transferred between these linkages (340 & 260) is relieved (ice I-^'ig 23). In the present invention the Trigger Linkage (340) will have rotated clockwise about Trigger linkage axis (341) tυ be pointing below the horizontal und the Slider linkage (260) will have rotated counter clockwise about Slider linkage axis shall (226) to be pointing in a downward direction (see Fig 2S) The pisΛon (221) of the auto shutoff or deactivation featuie will have changed the linkage meπns from the enabled configuration of the linkage mejns to the disabled configuration

(000138] Tins action will have disengaged the πdged connection between the I .inkflges (340 <fc 260) removing the force on the Spouts slidei assembly (200) and that will allow the Trunk spring (140) to return die bpouts slidei assembly (200) to its original eioscd orientation (see l'ig 17, 23, 24) while the Spouts trigger assembly (300) remains m place (see F]g 17, 23, 24) With the force on the Spouts slidei assembly (200) gone, the Trunk spring ( 140), which pushes on the Spouts slider assembly (2⁽X⁾) via the Trunk core (130), will spring back returning the Spouts slider assembly (200) to its closed orientation (see l'lg 17, 23, 24) In the sntne motion this action will have also returned the iruπk core (130) to its closed orientation (see Fig 4, 5, 6, 7, R, 19), sealing the Auto closure auto xhutoff spout closed (sec Fig 17, 23, 24) The Trunk core (130) will have been returned Io sandwiched the Trunk cores o-img (131) m between the Trunk core (130) and the Trunk tips (125) interior to piovide and airtight leak proof seal at the Trunks tip (125) (see l'ig 4, 5, 6, 7, 8, 19) As well, the airway Lh Jt hπd been opened up along the Λir Channel inlet tip (241 ) through the Piston cylinder (220), Trunk bodies airway ( 127) into he Trunk bodies ( 120) ulterior will have been interrupted as the Spouts slider assembly (200) W relumed to its closed orientation (see Fig 24) As the Spouts slider assembly (200) slides axinlly along the 'Inink body (120) back towards the lrunks lip (125) the piston Cylinders bottom air hole (228) will move out of communication with the Cavity between the I ranks lower o-πngs (128) to interrupt the airway that had been established an the Auto closme nuto shut off spout had been opened As the AuU) closure nuto shut off spout had actuated into the reset orientation the piston Cylinders bottom air hole (228) will have move axially along the 1 ruuk body (120) from the Cavity between lhe trunks lower o-πngs (128) to Lbc Cavity between the trunks upper o-rings (129) (reference changes in air hole (228) location between big. 21 and 24). The Cavity between the trunks upper o-rings (129) is formed by the Trunks o-ring til the tip (123) and the Trunks middle o-πng (122), which arc sandwiched ill between the Trunk bodies ( 120) externa- and the Slider bodies (280) interior (see Figui e 59).

fO0O139| ^'I his reaction of the αuto shut off feature will have returned the Cylinders bottom air hole (228) ol' the Spouts slidei assembly (200) and the Trunk core ( 130) to on orientation that provides the ϊ runk body (120) with an aπtight leak proot seal (see Hg 17, 21, 24)

I00U140J As the auto shutolϊ^' feature is activated in the Auto closure auto shutυif spout the flow of fluid will stop flowing through the Auto dosure aulo shutoff spout Λs the flow of fluid stops, the ventuii vacuum presume pioduced by the flowing fluid will also stop und in the absence of this negative pressure the Piston (221) that had been drawn down by the vacuum pressure (see l-^'ig 22, 23) will return to its original orientation (see Fig 24), In the absence of the vacuum pressure the Pistons return spring (223) will push the Pislon (221 ) baek up the Piston cylinder (220) until the top of the Piston arms (224) come in contact with the Piston retention hooks (225) which hold the Piston (221) in place within the Piston cyliiidei (220) (see Fig 9, 10. 18, 20)

[000141] The preferred embodiment of the invention would be that when the Auto closure nuto shutoff spout is in its closed and open orientation (500) the Linkage elbow (750) of the l πggcr linkage (340) and the Slidei linkage (260) would be sligbtly hy|ier-extended upward (see Fig 4. 5, I S, 20) ω that the force tiavchπg along the Trigger linkage (340) and the force traveling along the Slider linkage (260) are not in the same plane lhe angle between the Tπggei linkngc (340) and the Slider linkage (260) would be greater than 180? on the top side of these two components (340 & 260) and less than ISO? on lhu hoUom side (see Fig 4, 5, 18, 20).

[<WOΪ42| This hyper-extendcd state would turn a portion of the compression foices with in these linkages (340

A 260) into a slight upward force on the Piston arms (224) and Slider linkage stop (229) (sec Fig 4, 5, 18, 20) which would serve to keep these components (340 & 260) m a static state as force is applied to open the spout The provision of this hyperextensioπ m the linkages (340 & 260) would provide for greater stability to lhc linkages (340 &. 260) transferring Λc force and would work to prevent them from accidentally tripping into the reset orientation (see fig. 23) as the spout is in use

[0001431 Alternatively the Linkage elbow (750) could also be a strait I80> connection between the Trigger

Iinkugc (340) and the Slider linkage (26⁽1) which would rely on β spring such as the Trigger linkages cantilevered reed spring (343) to provide the same upward stabilizing force in nrder to maintain a static rigid connection preventing the Linkages (340 & 260) from accidentally tripping into the reset orientation

[000144| As the Auto closure auto shut oft^" spout is tnpped by the Piston (221) into the reset orientation the

Spouts slider assembly (200) will slide relative to the Spouts trunk assembly (H)O) and Spouts trigger assembly (300) which will remain relatively stationary (see Tig 17, 23,24) Before the Auto closure auto shut off spout is iπppcd into the reset orientation the Auto closure auto shut off spout is m the open orientation where tlie Dial indicator step follower (424) is* rusting on the Tiunks dial indicatoi step (124) (see Kjg 20, 22) As the Auto closure auto shut oft' spout is tripped into the reset orientation the Sliders dial indicntor step (270), which is positioned above the Trunks dial indicator step ( 124) (scs Fi g. 18, 20, 22, 23) will slide under the Dial indicator step follower (424) (see Fig 23) which will cause the Dial indicator (420) to iotato clockwise about the Dial indicntors pivot point (412) to display the reset text of the Dial indicators display (421 ) in the Covers window (41 1) (.see Fig 17. 23, 24)

[000145] To reset the Auto closure auto shut off spout the opeiator will just simply take the no^/lc away from the Gas container (40) and as the force, which was applied to the Auto closure mito shut olϊ spout (500) to Open it is removed (reference section 0026- 1 ), the Trigger return spring (330) will push the Spouts trigger assembly (300) towards the- Sliders up (201) returning the Spouts trigger assembly (300) of Auto closure auto shut off spout to its original closed (500) orientation.

[0001461 Λs the Auto closure auto shut off spoilt was tnpped into the reset orientation the Spouts slider assembly (200) had slid forward relalive to the Spouts trunk assembly (100) and Spouts trigger assembly (300) which had remained relatively stationary (sec Fig 17. 23, 24) In doing so the Trigger return spring (330) in between the Spouts slider assembly (200) and Spouts trigger assembly (300) had been compressed (refemux changes in the Trigger return spring 030) between Fig 19 and 24) Now, m the force, which was applied to the Auto closure uuto shut off spout (500) to open it is removed the Trigger return spring (330) will he able to expand to push the Spouts ttigger assembly (300) along the Slider body (280) towards the Sliders tap (201 ) returning the Spouts trigger assembly (300) of Auto closui c auto shut off spout to its original closed (500) orientation (see Fig 3, 4, 5, 18)
