2 Claims.

This invention relates to fluid dispensers, and aims to provide a device byl means of which a mixture of two fluids commonly used as a syrup and soda water, or a liquor and soda water, may be selectively or simultaneously passed into a container, such asa glass, the quantity of the syrup or liquor thus dispensed being predetermined by the setting of a regulating means forming part of the device. V

The above and other objects will become apparent in the description below in which characters of reference refer to like-named parts in.

the accompanying drawings.

Referring briey to the drawings, Figure l f is a side elevational view of the device.

Figure 2 is a bottom plan view of the same.

Figure 3 is a cross-sectional view taken on the line 3-3 of Figure 1.

Figure 4 is an erected cross-sectional view taken on the line 4-4 of Figure 2, showing the liquor regulating means in one position.

Figure 5 is a fragmentary cross-sectional view of the liquor chamber, of Figure 4, showing the liquor regulating means in another position.

Figure 6 is a fragmentary side elevational View of the device, partly in section, and showing the liquor regulating means in a third position.

Referring in detail to the drawings, the numeral IDVindicates a transparent cylinder having screw caps I I and I2 at the top and bottom, respectively, these members enclosing the syrup or liquor chamber I3. The caps II and I2 have axially aligned threaded openings I4 and I5, respectively, therethrough.. A tube I6, threaded on both its exterior and interior surfaces, projects threadably downward through the opening I4 and has a knurled ring Il on its upper end. A tube I8, threaded on its exterior surface only, projects upward through the opening I5, and has a knurled ring I9 on its lower end. A packing nut I2a surrounding the tube I8 is turned up against the cap I2, Within the upper tube I6, a thinner tube 20, with threads on its outer surface only, is in threadable engagement with the inner threads of the tube I6. A tube ZI, having its interior surface smooth throughout and its exterior surface smooth except for threads 22 on the lower end of its exterior surface, is slidably mounted within the tube I8. A smooth-surfaced tube 23, having a'collar 22 at a point nearer its upper end, is slidably mounted within the tubes CSI 20 and 2l, with the collar 24 positioned between the adjacent extremities of the tubes 20 and 2I and serving as a limit stop in the approach of the latter tubes toward each other. It is to be noted f that the tube 2l has a flange 25 on its upper end, which overlaps the upper end of the tube I8. Just above the collar 24, a transverse opening 26 passes diametrically through the tube 23, and a similar opening 21 is provided just below the collar. The threaded end 22 of the tube ZI projects through and threadablyv engages an opening in a horizontal brace or support 28. A knurled nut 29, having a smooth opening therethrough,

through which the tube 23 projects slidably, is

screwed on the end 22 of the tube 2|, and retains the brace 28 between the ring I9 of the tube I8 and itself. Near its lower extremity the tube 23 has a shoulder 30 from which the reduced stem 3l of this tube projects through an opening 32 in a member 33 described below. The lower extremity of the stem 3| is threaded, and a knurled nut 34 limits the member 33 to movement between Ythe latter nut and the shoulder 30. Y A coiled spring 35 normally urges the member 33 awayv edgescrew threaded,V and being further providedv with an internal shoulder 38. A tube or` stem 39 is slidably mounted in the tit 3B and the head 4Q on its upper extremity is adapted to rest on the shoulder 38. A knurled nut 4I surrounds the projecting end ofthe tit 36, and the stem 39 projects slidably through a smooth central opening therein. The construction of the lower end of the stem 39 is similar to that of the lower end of the tube 23, the shoulder being shown at 30a, the reduced portion at 42, and the nut on the end at 44, the opening in the member 33 through which the portion 42 projects being shown at 43, and the spring at 35a,

A cylinder 45 is provided with a threaded tit 4B which registers in the threaded upper end of the housing 3l. The upper end of the cylinder 45 also has a threaded tit 48 which is engaged by a knurled nut 49 having a smooth opening through its center. The cylinder 45 has a smooth axial channel in which a tube 50 is slidab-1e.- The upper end of the tube 50 is widened to form a neck 5I having external threads on its upper extremity. The upper peripheral surface of the cylinder 45 is also knurled, as shown at 53. The stem 39 has a transverse opening 54 just below its head 40, extending diametrically through the stem.

The device is held in upright position suitable means, not shown. A hose or pipe, not shown, leading from a source of liquor, syrup or other uid supply, is connected to the top of the tube 20. A second hose or pipe, not shown, leading from a tank containing carbonated orY soda. water, is connected to the top 5.2 of the tube 5B. The member 33 serves as a handle or lever which'is operated by pushing either end thereof upward, or the entire member upward at once. It is obvious that when the right hand end (Figure 4) is pushed upward a suicient disby any E tance to raise the opening 34 of the stem 39 clear of the shoulder 38, the soda water will pass from the housing 31 through the stern` 39 and out through the lower end of the stem.

In Figure 5, both openings 26 and 21 are shown closed; hence, assuming that the flow of syrup into the top of the tube is on, the same Will be checked at the opening 26 by the lower periphery of the tube I6 and the collar 24. This is the condition in which the device may be kept When not in use, as, for instance, over night, and is attained by screwing down the nut I1 (since the tube 20 is permanently attached to the syrup conduit or pipe, it will not be rotatable thereafter). To place the device into condition for use as a dispenser, the nut I1 is screwed upward until the lower edge of the tube I6 rises clear of the upper opening 2t in the tube 23, as shown, in Figures 1 and 4, which also show the lower opening 21 closed by the upper end of the tube 2I. When the upper opening 26 is thus freed, syrup will be Vfree to pour down through said opening and into the chamber I3. To permit the syrup to flow into the chamber, the left hand end of the lever 33 is pushed upward (and held in that position) a suicient distance to partly unseal both openings 23 and 21. When the lever in the chamber rises above the lowest point of the opening 21, it will ow down the tube 23 below the collar 2d, and as soon as it begins to ow out at the bottom of the tube 23, the lever 33 is released, the spring 35 then causn ing it to draw down the tube 23 and seal the opening 21 while fully unsealing the opening 26.

through the opening 23 until the air at the top of the chamber will have been compressed to a` point at which its. pressure equals that of the incoming syrup, and then the incoming flow will stop, a level somewhat above the uppermost point of the opening 26. The flowing syrup may be given a sufficient pressure by a force pump or by gravity.

In use, a glass is held under the device with its rim surrounding both nuts 34 and M. The left hand end of the lever 33 is pushed up, thus unsealing the opening 21. The escape of the syrup through the opening 21 will be enhanced at iirst by the pressure of the trapped air, mentioned above. The lever is held in that position until the level of the syrup in the chamber has fallen to the level of the lowest point of the opening 21, at which time the outward flow Will stop. The pressure against that side of the lever is then released and the right hand side of the lever is then pushed up thus causing soda water to flow into the glass, as previously described, the latter flow being stopped when the desired amount has been dispensed, by simply releasing the lever. If both ends of the lever are moved together, the limited quantity of syrup, above mentioned, will flow into the glass, and the soda water will ow simultaneously. If desired, the lever could be operated by applying the rim of the glass thereagainst.

The amount of syrup represented by the volume or" the disc between the topmost level (where the air pressure balances the incoming syrup pressure) and the bottonunost level (the lowermost level of the opening 21) is the portion dispensed each time the glass is thus applied to the left hand end of the lever. When the left hand end of the lever has been permitted to fall, as just mentioned, with the consequent sealing of the opening 21 and unsealing of the opening 26, the incoming syrup will again flow into the chamber to the same level mentioned above, at which the air pressure balances the syrup pressure. Thus,

`each portion of syrup thus dispensed will be of the same volume. If it is desired to reduce the volume of each portion, the nut I1 may be screwed down', so as to reduce the area of the opening 26 when the tube 23 is in raised position by bringing the lower edge of the tube 2U partway down across the said opening.

It is obvious that a combination dispenser of both syrup and soda water, or any other desired combination of fluids, has been provided, possessing the many useful and practical features which need not be mentioned specifically.

Obviously, modications in form and structure may be made without departing from the spirit and scope of the invention.
