Application filed January 29, 1923. rial No. 615,623.

To all whom it may concern:

Be it known that I, WILLIAM N. DAMON, a citizen of the United States, and a resident of San Francisco, county of San Francisco, State of California, have invented a new and useful Dispensing Faucet, of which the following is a specification.

The present invention relates to improvements in dispensing faucets and has particular reference to a faucet intended to'be used in connection with soda fountains such as are commonly used for the dispensing of root beer, coca cola, ginger ale and the like. The particular object of the. invention is to provide a faucet that will allow difi'erent kinds of syrups to be dispensed in combination with carbonated water and that will cause the syrup to be mixed with the carbonated water within the faucet. A further object of the invention is to provide. means in combination with the faucet causing the supply of carbonated water to be replenished each time a portion of the same is withdrawn for the purpose of serving a drink. A further object of the invention is to provide means in combination with the faucet-for replenishing a supply-of carbonated water independent of the withdrawal of the same. Further objects and advantages will appear as the specification proceeds.

The preferred form of my invention is illustrated in the accompanying drawing in which Figure 1 represents a vertical section through my device as adapted to a dispensing barrel, Figure 2 a top plan view of the same, Figure, 3 a vertical section through a valve used in combination with my faucet for replenishing a supply of carbonated water while the faucet is rotated into an operative position, Figure 4 an enlarged detail view in vertical section of the interiorparts of my faucet, Figure 5 a horizontal section through the same along line V--V of Figure 4, Figure 6 a vertical section taken along line VT-VT of Figure 5, Figure 7 a vertical section taken along line VIL-VTT of Fi ure 5 and I Figure 8 a vertical section a ong line VHF-VH1 of Figure 5. ile I have shown only the referred form of the invention it shoul be understood that various changes or modifications may be made within the scope of the'claims hereto attached without departing from the spirit of the invention. It ho ld e p r icularly understood that I throu h which while in the following description In device is described as dispensing three ifierdispensing barrel (2) well known in the.

art and therefore not illustrated in detail. It might be briefly explained that the barrel contams means for carbonating water, fresh water bein supplied to the same. through the ipe (3% from any suitable supply such as t e city water pipes, and'entering the pipe from below as viewed in Figure 1. The carbonated water communicates with the faucetthrough'the tube (4). The dispensing barrel also contains three receptacles containing syrups of coca cola, root beer and ginger ale respectively, the coca cola entering the faucet through the pi e (6), the gin er ale through the pipe and the root eer through the pipe (8) and all the pipes including the. one carrying the carbonated water are arranged vertically above one another as shown in Figures 1 and 4. From the barrel extends outwardly an embossment (9) to which the housing (11) of my faucet is secured by means of a threaded sleeve (12), a suitable washer (13) being interposed between the housin of the faucet and the embossment. The ousing itself is provided with four ports (14), (16), (17) and (18) communicatin with the four pipes (4), (8), (7) and (6 respectively, the our ports being in a separate block (11) slidable in the housing and having a concave end terminating in the vertical bore (19) of the faucet with a gasket (21) having perforations registering with the ports interposed between the housing and the valve (22) in the bore of the housing. The latter valve 22is a straight cylinder and is adapted to be rotated in the housing by means of a handle ('23) and is provided for selective alignment with the port (14) the carbonated water is dispense with five radial passages (24), (26), (27), (28), and (29), disposed in peripherally spaced relation, each assage communieating with a vertical dischar e assage (31), (32), (33), (34) and (36%. t will be seen that when the valve is in the position indicated in Figures 1, 2 and 5 none of the passages w-ithinthe valve registers with the p r (14) and this p s ti n w l t ere gasket (21) by means of the nut 12.

' is brought into registr fore. be referred to as the neutral position. The passage (26) is smaller in diameter than the other passages and is designed to dispense carbonated water in a fine spray. Its discharge passage (32) is disposed n the center of the valve while the other discharge passages are arranged at a radial distance from the said center.

The cylindrical valve is adjusted agamst interleakage of the various ports by drawing it up as tightly as desired against ,the

The valve normally occupies the position shown'in the drawings, that is the neutral position. If thevalve as viewed in Figure. 2 is'revolved anti-clockwise into the first position shown in dotted lines the passage 26 with the port 14 and a fine spray 0 car onated water is 'dispensed. If it is further revolved into the second position the passage (24) registers with the port (14) and carbonated water is dispensed ina coarse spray. If the valve is turned clockwise as viewed in Figure 2 into any of the three positions shown in dotted lines a coarse spray of carbonated water will be delivered.

The valve is also provided with three radial ports(37), (35) and 39) disposed in the vertical planes of the t ree passages (24), (28) and (29) and in the horizontal planes of the three ports (16), (17) and 18) respectively, and these three passages (37), (35) and (39) also communicate with the vertical discharge passages (31), (34) and (36) respectively so that when they are brought into registry with the ports (16), (17 and (18) respectively they will allow one of the syrups to be delivered into a vertical discharge passage, while at the same time carbonated water is delivered into the same passage and mixes with the syrup within the valve, dropping on the mixing cup (41) in its mixed form.

'In recapitulation and with reference to Figure 2 designating the various positions of the handle of my faucet and to the other figures for the cooperative arrangement of the various ports and passages, the complete operation of the valve may be described as follows: Turning the valve from the neu tral position shown in full lines in Figure 2 counter-clockwise into the first position indicated in dotted lines will cause the passage (26) to re ister with the port (14) and will cause a e spray of carbonated water to be dispensed. Turning it farther into the second dotted line position will cause the passage (24) to register with the port (14) and also the passage (37) to register w1th the port (16) communicating with the root beer supply so that root beer and carbonated water w1ll be simultaneously delivered into the discharge passage'(31) and will be mixed in said passage before droping on the mixing cup (41). Turning the handle clockwise into the first dotted line position shown in Figure 2 will cause the passage (27) to register with the port (14) allowing carbonated water to be delivered into the discharge passage (33) in coarse form. Turning it farther into the second dotted line position causes the passage (28) to register with the port (14) for the delivery of carbonated Water and also causes the passage (35) to register with the port (17) communicating with a suppl of ginger ale, thus allowing ginger ale an earbonated water to be simultaneously delivered into the discharge passage (34) and to be mixed therein. Turning the handle farther into the last dotted line position causes the passage (29) to register with the port (14) while the passage (39) is brought in registry with the port (18) communicating with the coca cola supply whereby coca cola and carbonated water is delivered simultaneously into the discharge passage (86).

In combination with this dispensing faucet I provide means for controlling the supply of water into the carbonator by means of the valve (42) introduced into the pipe (3). The latte-r is shown in detail in Figure 3 and comprises a housing (43) communicating at opposite ends (44) and (46) with the pipe (3) and provided with a valve seat (47) disposed so as to accommodate a valve (48) having its axis arranged transversel to the direction of the pipe. The valve 1s normally forced on itsseat by means of a spring (51) hearing at its far end on a cap (52) threadedly secured on the housing. From the valve extends a valve stem (53) supported in the housing as shown at (54) and engaging with its far end (56) a toothed disc (57) associated with the valve (22) and rotated with the same by means of the handle (23). While the handle is in a neutral position or in any one of the dispensing positions previously mentioned the end of the valve stem (53) engages a groove of the toothed disc and allows the spring (51) to close the valve (48) but while the valve (22) is turned from the neutral position to an operative position or vice versa or between operative positions the valve stem (53) has to pass one of the teeth and causes the valve, (48) to be lifted off its seat thus allowing the carbonator within the dispensin barrel to receive a fresh supply of water efore and after each operation. In case this automatic means for replenishing the supply of carbonated water is not sufficient the operator may turn the handle (23) counter-clockwise as viewed in Fi ure 2 into the third dotted line position w ich causes the end of the rod (53) to rest on the last tooth (58) and may leave the handle in this position until a sufii'cient supply of carbonated water is obtained. In this latter ill annexes position none of the passages in the valve (22) registers with any of the ports in the valve housing and no liquid is dispensed.

It will be noted in view of the foregoing that in the operation of my faucet the handle snaps into the various port alining positions through the action of the tooth disk (57) cooperating with the resilient pressure of the valve stem (53) wedging between the teeth; also, that although the operator may freely turn the faucet handle to pass over ports not wanted in order to arrive at the port desired, this is done quickly with so little escape of the undesired syrup that it is of no vconsequence in view of the great gain in simplicity and speed of operation as against the complexity of faucets wherein auxiliary valves are worked by another motion of the handle after arriving at the proper place.

I claim: u
