Application led; November 16, 1921.

To all whom t may concern.

Be it known that we, CHARLEs L. BASTIAN and HJALMAR MA'rHisnN, citizens ot the United States, residing at Chicago, in the county of Cook and State ot Illinois, have invented certain new and useful improvements in Dispensing Valves, of which the following is a specification.

'lhis invention relates to dispensing devices for carbonated beverages and has particular reference to the, dispensing valve. rlhe primary object of the invention is to produce a simple valve which will supply plain water in a coarse stream, and carbonated water in either a coarse or ne stream.

Another object of the .invention is to produce a valve structure in which a single movable valve member will control the flow ot the two liquids and supply one of them in either a coarse or a tine stream, as desired.

@ther objects will become apparent as the description is read in connection with the accompanying drawing showing a selected embodiment of the invention, and in whichlig. 1 is a plan view showing the different .positions of the valve handle in dotted lines;

Fig. 2 a vertical section view;

Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 2, sliowinv the arrange ment ot outlet ports in the valve casing; and

Fig. 4 is a transverse section on the line 1 -4i of Fig. 2 showing the arrangement oic ports in the valve.

Referring to the'reiierence numerals on the drawing, indicates the valve casing having a chamber 11 therein and being litted at its upper end with a bonnet 12 screwthreaded thereto as indicated at 13. @ne side ot the casing is provided with a threaded nipple 14 adapted to receive coupling 15 by which the valve is secured to draft arm 16. lNithin the draft arm are arranged a pipe 17 for plain water, and a pipe 13 for carbonated water. The pipe 17 is connected with the chamber 11 by a passage 19., and the pipe 18 is connected with the chamber 11 by an angular passage 2O which enters the chamber at the center oit its bottom. The bottom of the chamber is supplied with an outlet passage 21 for plain water and outlet passages 22 md 23 tor carbonated water. 'lhe passage 22 is connected wit- DSPENSTNG VALVE.

a jet nozlzle 24 while the passages 21 and 23 communicate with the nipple 25 having a spray grating 26 and equipped at its lower end with a. hard rubber nozzle 27. The ob- ]ect of the grating 26. is to break up the stream ot either p ain or carbonated water and make it tall from. the nozzle 27 in a solid stream inthe customary manner.

A valve gasket or packing 28 of leather or other suitable material is pressed tightly into the chamber, against the botton o1 the chamber, and has passages forming continuations of the passages 21, 22 and 23. Seated on this gasketor packing is a rotary valve 29 having a stem 30 journaled in the bonnet 12 and equipped with a stuling box 31 and an operating handle 32. rlhe valve has a large passage 33 extending therethrough and adapted to align with the passage 21 to establish communication between the pipe 17 and the spray nozzle 27, and another passage 34 somewhat {Ll-shaped in form, to establish communication between the passage 20 and the assages 22 and 23. @nel arm 35 of this [tl-shaped passage is co-axial with the disc and aligned with the passage 20, and the other arm 36 or this passage is substantially parallel to the arm 35 and coinmunicates through the same side of the valve with the passages 22 and 23.

Nonmally, the position of the handle 32 shown in Fig. 1 corresponds to the position ot the valve when all outlet passages are closed. By moving the handle to the dotted line position A, the passage 33 inthe valve is aligned with the passage 21 in the valve casing, and plain water is allowed to pass freely from the pipe 17 through the passage 19 into the chamber 11, and thence through the valve and in the bottom ot the casing to the spray nozzle 27. By moving the handle to the dotted line position l5, in Fig. 1., the arm 36 oit the passage 34C is aligned with the passage 22 in the bottom of the casing, and carbonated water can pass freely from the pipe 13 through the passage 20 to the passage 3a and the passa-ge 22, to the spray nozzle 211. By placing the handle in the dotted .line position C, the arm` 36 oi' the passage 3a is aligned with the'passage 23 in the valve casing, and carbonated water is sup e pli ed to the spray nozzle 27.

.ln order to hold the valve 29 properly seated on the gasket 23, we provide a spring 37 wound about the stem 30 and pressed between the bonnet andthe valve disc; to eli` ininate friction as much as possible, the ball bearings-38 are interposed between the bonnet and a ball race 39 on to of the spring.

From the foregoing it willl be obvious that we have produced a very simple construction whereby plain water may be supplied l1 n a coarse stream, and carbonated water in' either a coarse or a fine straem. This construction, moreover, practically eliminates all leakage common to the spring and check valves heretofore used. B putting all the ports under the control o a single rotary valve, we produce a very simple device which practically never gets out of order, or requires adjustment.

We are aware that changes in the form and proportion and arrangement of the parts of our invention may be made without departin from the spirit or sacrificing any of the a vantaves thereof, and we therefore reserve the rig'lfxtto make all such changes as fairly fall within the scope of the following claims.
