This invention relates to a device for dispensing'soda States Patent A (carbonated water), either flavored or unflavored, as

desired.

An object of the present invention is to provide a soda dispenser adapted for use at soda fountains and at bars that constitutes a single valve-controlled device to dis- .pense soda alone, or with one of a plurality of syrups, or with more than one such syrup.

Another object of the invention is to provide a dispensing device in the form of a hand-graspable head and connectedto sources of soda and syrup, whereby dispensing therefrom into a plurality of containers is greatly .facilitated.

A further object of the invention is to dispense soda and syrup from a single and unitary head and to join such soda and syrup only after the same is dispensed rather than within the head. In this manner, intermixing of flavors within the head is obviated.

. A still further object of the invention is to provide a dispensing head. The inlet for soda and syrup is on one side of a dispensing axis and the controls'instituting flow of such soda and syrup are on the opposite side or end of the head with respect to the dispensing axis, thereby providing an arrangement enabling easy facility of operation. A yet further object of' the invention is toprovide a soda dispenser that embodies a novel pressure-compensating valve for the soda to smoothen the operation of the soda valve of the dispenser. v a The invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a working position and easily disconnected therefrom, economical-of manufacture, relatively simple, and of general superiority and serviceablity.

The invention also comprises novel details of construction and novel combinations and arrangements of The body may-be molded or rnachin'ed as desired of connected to said tubes 10 and the hood part 12 sheath constitutes a socket into which the head is fitted: In this case, 'four tubes 10 'are-shown-o'ne to conduct soda (carbonated water) to the head, and the other three to each conduct a difierent syrup to said'head. It will be realized that said tubes are separately connected to their sources of liquid and that pressure is used on said sources to force the liquid into the head.

The head 13- that is illustrated comprises, generally a housing'body 15, asoda dispensing valve 16 within said body, a centrally arranged syrup dispensing valve 17 within said head, two similar syrup dispensing-valves 18 also generally similar to the valve 17, a dispensing means 19 for the soda and/ or the syrup flowing past said valves, and a controller 20 for said valves and adapted to be actuated by thefingers of the hand that grasps the body 15.

a metal or one'of the rigid plastics.- Regardless how made, the same is formed to have a handle 21 ov'er-Which the hood part 12 of the sheath 11 is slipped andto which the .tubes 10 are connected. I Said handle is provided with an enlarged soda passage 22 midway between the sides of the handle, a smaller syrup passage 23 above the'passage 22, and two smaller laterally arranged passages 24. As can be seen in Fig. 5, the passage arrangement is symmetrical and is generally cruciform. At its end opposite to the handle 21, the body 15 is provided with a preferably spherical extension25 in Y which is formed a flow'passage 26 that intersects the passage 2 2 and is somewhat larger diametrally than said passage 22.. The edge of the head opposite extension 25 and the end thereof is suitably provided with grooves;

27 to house the controller 20. V I I While made as a separate part, a tube 28 constitutes a'fixed concentric extension withinthe passage 26 and is afiixed to the body by a tight fitof its squared end 29 in a squared seat provided in the body. The tube 28 reduces the pas'sage,2 6 to an annulus; A longitudinal bore 30 in tube 28;,intersects .a' transverse bore 31- and the latter is'aligned with the passage 23 so that flow from the'latter may eXit'frorn the end of thebore 30. By

making the. tube 28 to be at least flush with the end of body extension 25, or somewhat over-flush, such flow' passes outwardly from the head beyond theannular.

pass'age'26. In somewhat the same manner two other parts, which will more fully appear in the course of the following description. However, the drawing merely shows and the following description merely describes, one embodiment of the present invention, which is given s by way of illustration or example only.

In the drawing, like reference characters designate imilar parts in the several views. Fig. 1 is a small scale and broken side elevational view Kif the present soda dispensing head and a portion off the how tubes that supply the same.

Fig. 2 is an enlarged top plan view of said head. Fig. 3 is a longitudinal sectional view as taken on the line 33 of Fig. 2. i Fig. 4 i s'a broken plan View as seen-from the bottom of Fig. 3.

Fig. 5 is an enlarged cross-sectional view as taken on 7' omitted for this reason. Thesame normally stop flow bores 3-2 in-tube 28 .each terminate at intersecting bores 33. The latter, in turn, connect with aligned bores 34 in thefbody (see' Fig. 5),'the passages 24 each intersecting one of the .latterbores 34, Plugs 35 cap the bores-34 which, necessarily,- must be drilled from .the outside.

It will be clear' from the above that each of the three syrup pa'ssages23 and 24 has a separate means of exitto the end of tube 28' wholly independent of the flow passage 26. The flow in each said passage may be controlled as to amount by a restriction member 36 carried by a hushin'g37 in the handle-and extending adjustably in the flow port 38 of a nipple 39 in each passage 23 and 24. v

'The soda dispensing valve 16 is shown as a flow res-triotor 40 disposed 'in passage 22 and" formed with outer longitudi'nal grooves '41 that reduce the effective size of the flow in passage 22. A valve 42 normally closes the flow in said passage and the same, together with the restrictor '40, is located in the handle onone side of the head. a

The syrup dispensing valve .17 is also located on the handle side of the head between the nipple 39 and'the end 29" of the syrup-passing tube '28. As seen, in Fig. 3, the val've 17 is located in a restriction of passage; 23, is

backed by a spring 43711611 abutte'd: by :a springfretainer, Y

44.- .The syrup dispenjs ng" valves 18 are similar-tothe valves 17 and theiiindependent'illustration has been 2,931,792 2 re e 9 ofthe' in passages 24 in the same way that valve 17 stops flow in passage 23.

The syrup dispensing means 19 has already been described in connection with the body 15, the same comprising the tube 28, its squared end 29 and the passages therein.

The controller 20 for said valves 16, 17 and 18 comprises, generally, a balanced valve operator 45 for the valve 16, a trigger arm 46 to actuate said operator, an operator 47 for the valve 17, a trigger arm 48 to actuate the operator 47, an operator 49 for each of the valves 18, and a trigger arm 50 to actuate the operator 49.

As can be seen in Figs. 3 and 5, the trigger arm 46 encloses the trigger arms 48 and 50 and, therefore, overstands the same. The arm 46 is mounted on a pivot 51, has a part 52 that curves over the end of the head, and a forwardly extending part 53 that constitutes the actuation portion of the arm. As can be seen, also, said arm is housed in groove 27 formed therefor in the body of the head. The actuation or handle part 53 of said arm 46 is provided with three slots 53a (see Fig. 5).

Said arm 46 is arranged to engage the valve operator '45 which is connected to valve 16, to operate the same, by a spider 54 through which the tube 28 extends and which spans across the passage 26. The elongated slot 55 in said spider allows shifting operation and also passage of soda therethrough. A spring 56 is devised for biasing the valve 16 to open position but the same is ordinarily ineffective to open said valve against the pressure of the carbonic gas in passage 22. However, this spring may be so adjusted by a follower 57 that but a small pressure on the trigger arm 46 is needed to be added to the force of the spring 56 to efiect an effortless and smooth opening of the valve 16. It will be noted that the arm 46 is formed to have a power advantage so that finger pressure on the handle end 53 will produce successful operation.

The operator 47 extends through the bore 31 of the tube end 29 and through aligned bores that are extensions of passage 23. An operating head 58 is provided on the protruding end of said operator 47. The arm 48 is engaged with said head 58 in much the same way that the arm 46 is engaged with the operator 45. Thus, by moving said arm 48 on its pivot 59, the valve 17 may be opened from the end of the head body that is opposite to the inlet passage 23. An actuator button 60 is provided on said arm 48, the same having astem extending through one of the slots 53a provided in the arm 46.

The operators 49 for the valves 18 are controlled by the arms 50 in much the same way as described for operator 47 and arm 48. Actuator buttons 61 are provided on each arm 50 and the arrangement of buttons is substantially as shown in Fig. 2, the buttons being larger than the slots in arm 46 so as to interengage the arm 46 when any button is depressed.

By providing clearance between arm 46 and each arm 48 and 50, the soda valve 16 may be opened to dispense soda Without causing actuation of the valves 17 and 18. Hence, syrupless soda may be dispensed by depressing only the arm 46. If one of the syrups is desired to be dispensed together with the soda, that button 60 or 61 controlling the flow of the desired syrup is pressed, causing the handle 53 to be depressed without depressing the other buttons. Now, a flow of syrup from one of the bores 30 or 32 will join the annular stream of soda at or slightly beyond the extension 25 of the head. Two or even three syrups may be dispensed simultaneously. Adjustment of the control means 20 will provide the type of operation desired.

While the foregoing specification illustrates and describes what I now contemplate to be the best mode of carrying out my invention, the construction is, of course, subject to modification without departing from the spirit and scope of my invention. Therefore, I do not desire to restrict the invention to the particular form of construction illustrated and described, but desire to cover all modifications that may fall within the scope of the appended claims.
