In the drawings wherein similar characters of reference indicate corresponding parts in the several views of the preferred form of the invention, A designates a-web roll handling and supplying device which as shown in Figure 1 includes a frame 16, suitably secured to a base or floor 17. The web roll supporting member or reel 18 as shown in Figure 1, has two web rolls supported thereon; i. e., a fresh or replacement web roll 19 and an exhausting web roll 21, it being understood that as customary the web reel support may be swung or rotated to bring the web rolls into desired positions for feeding, transfer, etc., as hereinafter described.

A web end retaining and releasingmember "B forming an important feature of the present invention, a pair of which are employed, one at each end of the fresh roll 19,comprises an arm 22, composed of two pairs of sections or straps, 23, 24, as shown in Figure 3, slidably an'd adjustably joined in any suitable manner as by the slots 25, formed in sections 23, and theT-bolts 26, or other suitable fastening means which ride in the slots 25, and are threadedly engaged in the straps or sections 24, thereby serving to adjustably connect the. sections 23, 24, one of which 24, is slid longitudinally relatively to the other in order toaccommodate the member 13 to rolls of various diameters, when necessary or desired.

The section 23 is formed with or has secured thereto, a collar or annular member 27 which is rotatably mounted either directly on the core of the web roll which in this instance is the fresh roll 19, or on means hereinafter described which rotatably support the-web roll. The other section of the arm 22 is formed with or hassecured thereto a strip or tab holding and cutting instrumentality which comprises a jaw-shaped head or end 29 having an opening 31, which receives straps or tabs and the like, hereinafter described, which may have an adhesive on one or both sides or the top and bottom surface. Two straps 32, 33, preferably of paper or other suitable strip material, are preferably placed in helical relation on the roll 19 as shown by way of illustration in Figures 3 and 4 and hereinafter more fully explained. A knife Y or cutting element 34 is hinged or pivoted on a pin 35, secured in the end or head 29 and swings or rocks in a pair of similarly positioned slots 36, 37, formed in the upper and lower jaws 38, 39

respectively of the head 29. The knife 34 is main-- tained in normal raised position in the upper jaw 38 by a spring, hereinafter described, thus leaving the opening 31 between the jaws 38, 39 free for receiving the strap or tab 32, 33 and the other tab hereinafter mentioned; It will be observed the head of the knife 34 is provided with a widened or flattened portion 41, the: underneath side of which, acts as stop for the said knife when it abuts against the top of theupper jaw 38 after it has aoco'mplish'ed'its functions by severing the straps or tabs 32, 33,-while the topof the flattened portion acts as anvil or seat which may strike against abutments or marginal projections 42, formed or secured to the brackets or plates hereinafter referred to, forming a part of the webjoining or splicing member hereinafter described more fully.

The webgjoiningg a pair of arms 44, 4 relation to the shaft 46 which is rotatably supr splicing member comprises keyed or fastened in opposed po'rteddrrbearing hangers 47, suitably secured to slotted plate'48, having bent flanges 49, to which the brush assemblies 51 are fastened, ls adjustably secured by screw bolts 52 which ride in the slots 53 formed in the said plate 48.

As best shown in Figures 6. and 7, the head 29 of each of the web retaining and severing members at the opposite ends of the replacement roll 19 is provided with an internal spring 54 mentioned above, which is connected at one end to an inwardly projecting portion of the knife 34, and at the other end to an internal part of the head 29. The spring 54 serves to maintain the knife 34 in normal raised or inoperative position, leaving the opening 31 ofthe head 29 free to receive the straps or tabs 32, 33 preparatory to their severance by the knife'34, as clearly shown in Figure 6.

In Figure 7, the upper or flattened portion 41 of the head of the knife 34 is engaged with the abutments or projecting plates 42 and has been pressed downwardly through the opening 31 to the position shown within the slotted lower jaw of the head 29, thus severing the straps 32, 33.

By further inspection of Figures 6 and 7, it will be seen means for securing the pair of helically positioned straps or tabs 32, 33, mentioned above, and an additional pair of straps 55, 56,

which are also helically positioned on the body' portion of the roll 19 and in crossing or angular relation to the first mentioned pain of straps 32, 33,-are provided in the head 29,-the means comprising a pair of small 'rollers 57, having a knurled surface and reduced ends or axles 58, which are received in slots 59, formed in a por- ,tion of one of the side walls or surfaces of the head 29 which is formed or provided with a pair of shelving recesses or pockets 61 in which the said rollers 57 are secured by the engagement of the reduced ends 58 of the rollers 57 in the slots 59, above-mentioned. when the end portions of the tabs or straps 32, 33, and 55, 56 are passed under the knurled surface of the rollers 58, the sliding of the said rollers in the direction of the jaws 38, 39 of the head 29 will clampingly confine the straps as the rollers advance on the inclined or shelving surface 62 of the recesses 61.

The shaft 46 on which the arms 44, 45 of the web-splicing member 43 alluded to. above are fastened, has secured thereto, an operating lever 63, having a pawl 60 which coacts with a ratchet segment 64 fastened to one of the bearing hangers 47, the lever 63 providing means for manually operating the web-splicing member 43, whenidesired, and for moving it out of the path of the rolls when the roll support is rotated.

In order to bring the web of the deplacement roll'l9 to the same speed as the web of the nearly exhausted roll 21, a feeding belt 65, mounted on a pair of rollers 66, 67, secured on shaft 68, 69 mounted in a frame member 71, is provided. The shaft 69, it will be noted, has a gear 72 fastened thereon, the gear 72 being engaged by a gear 73, secured to a vertically positioned shaft 74, rotatably mounted in the frame 16 andpref'erably having an operative connectionwith the driving system of the printing machine, so that the belt 65 travels at substantially the same speed as the traveling web .W of the exhausting web 21. To

'75 the frame 16. To each of the; arms 44, 45, a dicated om the fore o ng details, but it will .end from tearing be more fully understood from the following de scription. I

On the free end of the replacement roll 19 which, as viewed in Figures 3 and 4, discloses a pair of intersecting or meeting helixes and which preferably is torn, notched, cut, or a portion removed therefrom to provide a more or less 'vshaped edge having the side marginal portions or tapering fish-tail ends 30, a pair of the binder ribbons or tabs 31, 33, referred to above, is pasted, it being observed that the said ribbons or tabs, after pasting, will be positioned in helical relation to the body portion of the replacement roll, and along the edge in substantial alignment therewith. The notching, tearing, or removing a portion from the free end of the replacement roll is most conveniently and expeditiously done by first applying or pasting the straps ortabs to the free end, the straps then serving as guides to tear out the portion of the free end alluded to. The said straps further provide a reinforcing means for the end fi. the web to prevent said web en the roll is rotated preliminary to making a web join.

The outer surface of the helically positioned straps 32, 33, is next smeared with a suitable adhesive, care being taken to prevent any adhesive getting on the body portion of the replacement,

'roll, while the ends of the same straps overlapping the opposite ends or sides of the fresh roll 19, are clampingly secured in the upper of the pockets 61 of each member B at the opposite ends of the fresh roll 19,; by engagingthe said ends under the knurled rollers 5'7 and thrusting the latter towards the jaws 38, 39 until the said overlapping ends are gripped between the knurled surface of the rollers and the adjacent shelving surface 62 of each of the pockets or recesses 61.. The other pair of helically positioned straps or tabs 55, 56, which are arranged in crossing or angular relation to said first-mentioned pair of straps 32, 33 are pasted on the body portionof the fresh web roll 19 with theirends also secured under the knurled rollers 57 in the lower of the pockets 61 of each member B, it being observed that the last-mentioned pair of straps 55, 56, serve mainly to sustain the web retaining and releasing member B in the operative body portion thereof while the latter is rotating in the direction indicated by the arrow, until the moment predetermined for the joining or splicing of the web of the replacement roll to the traveling web W of the exhausting roll after the peripheral speeds of both webs have been equalized.

Assuming the lower'web roll 21 to have been unwound or used to the amount indicated in Figure 1, the web reel support 18 will be swung or rotated to bring the fresh or replacement roll 19 to the position shown in the last mentioned figure. The feeding belt will now be lowered to operative engagement with the periphery of the replacement roll 19, and the latter rotated until the peripheral speed of same is equal to that of the traveling web W of the now nearly exhausted lower roll 21. J

It will now be seen that as the replacement roll rotates-with its free end bound to the body portion by the lower pair of . tabs 32, 33, the pair of members B of our invention, at the opposite ends of the fresh roll 19, sustained by the upper 'tabs 55, 56, will rotate therewith until approximately the moment when the peripheral speeds of the webs of both'rolls are approximately equal, whereupon the lever 63 is manipulated to turn the shaft 46 to swing the brush assemblies 51 against the traveling web W of the exhausting roll 21, thereby impinging the latter against the adhesive-smeared outer surface of the helically positioned pair of straps 32, 33 which are pasted on their inner surface to the fish-tail edge or end of, the web of the replacement roll 19. Almost simultaneously with the engagement of the brush assemblies 51 with the web W for applying same to the sticky outer surface of the straps or tape 32, the flattened head 41 of each knife or cutting element 34, will strike against the abutments 42 of the web splicing member 43, which may have shock-absorbing material secured thereto, thereby causing the said knife 34 to pass downwardly through the openings 31 and thus cutting both upper and lower straps or tabs 32, 33, and consequently causing the pair of web-retaining and releasing members B to completely release the end of the web of the replacement roll 19, now pasted to the web W of the exhausting roll, so that the web of the replacement roll may serve without the slightest impedance as a continuation of the web of the exhausted roll without delaying the operation Iofthe press in the slightest degree. Both of ,the'web-retaining and releasing members B, which are freely rotatable 0n the core engaging means of the fresh roll or the means supporting same alluded to above, will now. drop to inoperative or depending position, the web of theexhausting roll meanwhile having been severed by any convenient means. This completes the cycle of a change from one roll to another without' stopping or retardation, which may be repeated as many times as desired, or until the run has been completed. The invention is particularly designed and adapted to be operatively applied to practically all types of machines employing web roll-handling mechanism, since the application of the tabs and adhesive and the Securing of the tabs to the permanently mounted pair of members B require only a few moments. While the extremities of the fish-tail ends 30 on either side of the marginal sides of the free end of the replacement web roll 19 are shown as arranged in substantially the same relative position at each end of the web roll 19 and in helical relation to the body portion thereof. It is to be noted that one of the said fishtail ends 30 may be much shorter than the other or leading fish-tail end, and it will be apparent that if desired, the end of the web may be cut on along diagonal in which case, only one of the members B will be required, since one fork or portion of the fish-tail end alluded to above would be eliminated.

The helical arrangement of the tab or tabs and the like on the free end of the roll and on the sides or margins of the body portion thereof in'the forms shown, and the tearing or cutting 6 or otherwise removing a portion of the said free end of the replacement roll 19 to form the fishtail or helically positioned ends 30, in themanner indicated above, are also features of the present invention since they achieve by the utmost simplicity of means a highly efiicient way of confining the free end of the roll to the body portion while the said roll is rotating, it being observed that the said fish-tail? ends which are forwardly directed or leading on the replacement roll 19 while rotating in the counter-clockwise direction indicated by the arrows in Figures 1, 3, etc., when secured by the above-mentioned tabs or straps, will directly tend to exert a forward pull or drag and thus bind or confine the free end of the roll, while rotating, to the body portion. As pointed out above, the tearing of the free end of the replacement roll is accomplished with certainty and dispatch by preferably first pasting the strip material or tabs in helical fashion on the free end, and then simply tearing out the portion of material from the V-shaped space between the said helically positioned straps, using the tabs or straps as guides for this purpose.

It is to be noted that by pasting the strip ma,- terial or tabs in helical fashion to the body portion of the roll, instead of parallel'to the axis or longitudinally of the roll, distinctly serves to prevent air from getting under the free end portion of the web, while the roll is rotating, and likewise the tearing or otherwise removing material from the free end of the web which is conveniently done by using the tabs as guides for the tearing to provide the fish-tail or equivalent portions is particularly adapted to prevent air from getting under the free end of the web of the replacement roll during rotation.

In Figure 8, we have illustrated suitable roll chuck mechanism for rotatably supporting web rolls in a web roll or reel support, to which mechanism the invention can be quickly attached. The chuck mechanism here illustrated provides means for quick and fine axial adjustments of the members which engage the web roll cores so that the rolls may be loaded into the support expeditiously.

By inspection of Figure 8, it will be noted the section 23 of the strap or arm 22 of the web retaining and releasing member B of the invention is bolted or otherwise suitably fastened to the rotatably mounted annular member or collar 27, forming a part of the chuck mechanism herein mentioned. The supporting arm 78 of the present chuck mechanism is provided with a sliding sleeve 79, having a hand wheel 80, providing for a quick axial or lateral adjustment of the sleeve '79 and the parts connected thereto. A block 81, slidably keyed to andconcentrically positioned within the sleeve has a cone-shaped head 82, which enters-the core 88 of the web roll 19. The comparatively quick axial or lateral adjustment of the sleeve 79 and the block is effected by an arcuate groove85 in the sleeve '79 and a pin 86 in a hub 8'7, forming a part of the supporting arm 78, it being understood that the rotation of the hand wheel 80 will move the sleeve when turning,

' in an axial direction by the coaction of the fixed which is fastened to the block 81. The outer.

portion of the screw 89 is threadedly engaged in the hub 93 of a hand wheel 94, employed for making fine adjustments, the hub 93, having an annular recess or groove 95 in which a second thrust collar 96, secured by screw 97 to the handwheel 80,-is engaged.

In operation, it will be observed that when the smaller hand wheel 94 is rotated for fine admeans of supporting web rolls in web reel supports of the general character herein indicated.

The parts of the chuck mechanism illustrated in fragmentary section at the right hand side of the web core 83 shown in Figure 8, are assumed to be non-adjustable or in fixed position with the exception of the rotatable cone-shaped head 82, while nearly all of the parts of the chuck mechanism at the left hand side of the same core 83 are movable or adjustable as indicated, so that the fresh and exhausted web roll can be moved into and out of position as required, from one side alone of the web reel support.

In Figures 10 and 11, we have shown a modified form of the invention which requires the use of only one comparatively short strap or tab at each end of the fresh web roll 19 instead of two as in the form shown in Figures 1 to 9 inclusive. In the present instance, the web releasing and retaining member C 'of the form shown which also serves as an anchorage for the strip material or tabs differs from the member B in that the jaw-shaped head 98 of the instant form has an offset or laterally projecting portion or ledge 99, the top surface of which, as at 101 is substantially flush with the lower jaw 102 of the head 98. A- portion of the single binder ribbon or tab 103 here employed, after one end thereof has been pasted on its under surface to the body portion of the roll 19, preferably in helical relation thereto, as shown in Figure 11, is passed over the said top surface 101, thence downwardly and around the lower projecting portion 104 of the said ledge 99 and thence obliquely or angularly upward as at 105 over the top. of that portion of itself which rests on the top of the ledge 99, continuing in a diagonally crossing direction over an adjacent edge of the free end of the fresh web roll 19 to which it is pasted on its inner surface. While the sequence just described is preferable, since the portion of the binder strip 103 adhering to the free endis uppermost and consequently free after severance by the knife 106 to be carried away with the traveling web of the replacement roll after being glued thereto, it will be understood that, if desired, the said strip 103 may first be pasted to the free end of the replacement roll, then passed over those portions of the jaw-shaped head 98 enumerated above, then passed over the portion of the strip sticking to the free end, and finally pasted to the body portion of the replacement web roll. In the last recited sequence, the placing of that portion of the strip material immediately adhering to the free end of the web underneath the portion of the strip glued to the body portion would not be as advantageous as the preferable arrangement since there would-be a temporary overhanging or superincumbent por-.

tion of strip material that would be thrust aside as the free end of the replacement web became 5 inclusive, wherein the free end of the replacement roll is notched by first pasting the straps 32, 33

thereon and then a portion of the free web end torn out while using the said straps as guides. The second pair of straps 55, 56 are subsequently pasted. on to the body portion of thereplacement roll and may be used atonce to support the member 13 either before or after the smearing of the outer surface of the first-mentioned pair of straps 32, 33 with adhesive. The knife 1060f the member C performs practically the same functions as inthe form shown in Figures 1 to 9 inclusive.- In this form, however, the folded over or crossing portions of the single strap or tape 103 at each end of the web roll 19, are simultaneously cut as the knife 106 of each of the pair of members C employed, one at each end of the roll 19, engages the abutment or trigger projections mentioned above. 1 a

In Figures 12, 13 and 14, a modified form of the invention is shown which employs one strip of .adhesive tape or strap, and-eta, 106, which may be perforated or creased as at 107 to facilitate tearing or severance thereof, is pasted to the free end of the web roll 19, in helical relation to the body portion thereof, one end or portion of the tape 106 being in a strap or tape and the like securingmember 108 which is similar in some respects to the strap or tab securing member, best shown in Figures 6, 7 and 9. The member 108 includes a frame or shell 109, having a shelving pocket or recess 111, in which a tape or ribbon ,engaging roller 112, having a knurled surface is arranged. The-knurled roller 112 has reduced ends 113, which are slidably received in elongated slots 114, formed in the shell 109, thus permitting the roller to be slid in the pocket 111 for the purpose of clampingly engaging the tape 106 confined against the shelving surface the said pocket 111 and the adjacent knurl surface of cal the roller 112 in the manner described above in connection with the details shown in Figures. 6, 7 and 9. A portion of the shell or frame 109 has flanges asat'l15 which are received in grooves 116, formed in an annular member 117 for a purpose which willappear hereinafter, while a rack 118 is provided on one end or edge of the shell 109. The rack 118 is engaged by a pinion 119 rotatably mounted on a stud or pin 121, the'pin 121 being secured to the annular member'117, the

pinion 119 meshing with a rack segment 122,

formed on an arcuate strap 123, which is fastened to an annular portion 124 formed with or secured to an arm or trigger member 125, which coacts with a pin or'stop 126, secured to an arm 127, or a part of the adjacent web splicing member or frame. The arm 125 is held in the normal position shown against a stop pin 128, and is secured to the annular member 117 by-a spring 129, fastened at one end thereto, the other end of the spring being attached to a cam-shaped member or latch 131, having a slot 132, in which rides a pm 133, secured to a forked extension or proj'ec-, tion 134, of the shell 109.. The annular member 117, as indicated in Figure 12 by the dotted line at the lower portion thereof, may have a counterbalaneing weight 130, if desired. The camshaped member or latch 131 is provided with a pin 135, fastened thereto, to which is secured one of the looped ends 136, respectively of a clutch member or band 137, frictionally engaged with the hub 138 of the cone-shaped head 139 of the web core engaging memberl141, shown in fragmentary section in Figure 13.- The other looped end 142 of the clutch member or band 137 is fastened on a pin 143 on the annular member 117, serving as a pin or fulcrum for the camshaped member or latch 131', the pin 143 traveling .in an arcuate slot 144, formed in the annular portion 124 of the arm 125, for a purpose hereinafter described. The functions and manner of operation of the modified form of the invention shown in Figures 12, 13 and 14 has been in part indicated by the foregoing details, but willbe more fully understood from the following description:

Assuming as best shown' in Figure 12, the fresh" or replacement web roll 19 has been operatively mounted on the member 141 with its free end notched or torn to provide the helically positioned portions engaged by the adhesive tape 106, a portion of which latter is clampingly held in the tape securing member 108; and that the said fresh roll and the core-engaging member are revolving at normal press operating speed, and also assuming the clutch 137 to be as illustrated, in frictional engagement with the hub 138, and the trigger arm 125 to have struck against the stop 126, it will be noted that further rotation in a counter-clockwise direction of the assembly shown in Figure 12 will first cause the immediate severance or breaking of the helically arranged adhesive paper tape 106 at the point of the perforations 107, thus completely liberating the free end of the fresh roll 19 at the time when the traveling web of the exhausted roll is being or has been applied to the sticky upper surface of the said tape in order to bind or splice same, and consequently the web of the fresh roll, to the web of the-exhausted roll, in the manner described above in connection with Figures 1 to 9 inclusive.

It is to be noted that the momentum of the annular member 117 will carry it ahead after 4 rack 118 and rack segment 122, and consequently causing the shell 109 and its attached rack 118. to move in the groove or slides 116.- The movement of the tape securing member 108 along the grooves 116 will, as mentioned above, first cause the immediate severance or breakage of the adhesive paper tape 106 at the point of the perfora-' tions 107 thus completely liberating the free end of the roll 19 from the body portion of the roll in order to permit the unimpeded attachment of the free end of the roll to the traveling web.

The separation of the looped ends 136 and 142 will free the clutch band 137 from frictional engagement with the hub 138 of the web-core en gagingmember 141, and as a consequence" will permit the hub 138 to turn freely relatively to the clutch assembly and the parts connected thereto. It willbe noted that when the clutch band 137 is released after the pin 133 on the moving tapeengaging member 108 has travelled in the slot 132 sufiiciently to engage the end of same and move the latch 131' about as pivot pin 143 enough to latch 131 to the position shown in Figure 12 will be counter-balanced by the available torque of .,the revolving hub communicated through the now slipping clutch band 137 on the said hub. This will produce at the time now indicated, a condition of equilibrium between the clutch and the tension spring 129 resulting in an idling of the 'which comprises strip material pasted adjacent an edge of said free end so as to overlap an end of the body portion and anchored at said end to a member rotated with said web roll.

2.
