SAMUEL TILIDEN DARE, OF NEW WESTMINSTER, BRITISH COLUMBIA, As SIGNOR 0F ONE-FOURTH TO MATTHEW J. PHILLIPS, ONE-FOURTHTO J'AMES'HENRY DRINK DISPENSII VG MACHINE.

Application filed January 30, 1932. SeriatNo. 589,940.

My invention relates to improvements in drink dispensing machines which are particularlyadapted for use in dispensing beverages having a pulp content or which are subject to sedimentation of some desirable component of the liquid.

The objects of the invention are to provide means whereby the liquidis under constant circulation through the dispenser ;'to provide means whereby the liquid dispensed is accurately measured, and to provide means whereby every drink dispensed is registered so that the total value of the commodity sold may be readily computed.

The invention consists of a circulatory system, including a pair of measuring cups and a valve capable of disrupting either cup from the circulatory system and discharging its contents, as will be more fully described in the following specification and shown in the accompanying drawing, in which Fig. 1 is a rear view of the invention with the cover removed from the casing. I

Fig. 2 is a sectional view of the invention taken on the line 22 of Figure 1.

. Fig. 3 is a sectional plan view of the valve.

Fig. 4 is a detail view of the registering mechanism, shown in operating position.

In the drawing like characters of reference indicate corresponding parts in each figure.

The numeral 1 indicates generally a casing having a front wall 2, side walls 3, a base 4 and a. top wall 5. The casing is adapted to be mounted upon a suitable counter (not shown) convenient to a receptacle (not shown) containing the beverage to be dispensed.

Extending upwards through the base 4: is a suction pipe 6. Fitted to this pipe is a valve 7 consisting of a substantially cylindrical body 8 having an inlet port 9 connected with the pipe 6, two flow and

return ports

10 and 11 and a discharge port 12 to which a discharge pipe 13 extends through the wall 2 to a convenient filling position in front of the casing.

Fitted within the valve body 8 is a rotatable core 14 having two elongated peripheral ported

passages

15 and 16, the former being approximately 190 degrees in length and the latter approximately 100 degrees. The core is fitted with a vertical stem 17 from the up per extremity ofwhich a downwardly turned operating lever 18 extends. I v A continuously driven pump 19 is provided, which has a suction pipe 20 leading from the beverage receptacle and is connectedon;

its discharge side to the pipe 6. Pipes 21 lead from the

ports

10 and 11 of the valve body 8 which extend upwardly and return through the casing 1 back to the beverage receptacle below the liquid level. These pipes preferably terminate at such a distance from the suction pipe 20 as to ensure a thorough circulation of the beverage. In-- termediate the length of the pipes 21 and inwhich is-soplaced that, the total recorded thereon may be seen through a viewing opening 25. The recorder is provided with a trip arm 26, which on being raised, increases the recorded total by one. H r

Pivotally mounted upon a bracket 27 attached to the front wall 2 is a rocker 28 consisting of a semi-cylindrical portion 29 which extends around. the rear side of the stem :17 and cut away in the form of a V to form a cam 30. To the front of the portion 29 a finger 31 extends into contact withthe underside of the trip arm 26. Extending radially from the rear of the stem 17 is a pin 32 which normally lies in the crotch-of the .V (so that when the stem is turned by means'of the operating lever18, the pin 32 moving along either of the inclined sides of the V causes the rocker 28 to swing, raising the fingerBl, which in turn raises the trip arm 26 to increase the total on therecorder 24. Obviw ously a turn of the stem in either direction will cause an upward movement to be imparted to the trip arm. y 1 I In-operation the pump 19 is set in motion. This draws liquid from the beverage receptacle, passes it through the port 9 of the valve body 8, thence around the ported passage 15 in the core 1 1 in opposite directions and out.-

throw, which is approximately 45 degrees" from itsnormal central position, the

ported passages

15 and 16 will be so disposed as to establish communication between the

ports

9 and 11, that the flow from the pump will be from the pipe 6 through one pipe 21 and the glass cylinder. 23 back to the beverage receptacle, and the ported passage 16 will be so disposed as to establish communication between the portslO and 12, so that the liquid contained in the glass cylinder 22 may v flow outwards through the discharge pipe 13.

' Ifthe lever 18 is .moved in the opposite direction, the circulation will be maintained through the cylinder 22 and the liquid from the cylinder 23 will be discharged through ey P pe As soon as the lever is restored to normal position, circulation will take place through both cylinders and the trip arm 26 will be restored to normal position, so that the counter will be setfor furtheroperation.

. What I claim as my invention is:

1' A drink dispensing device comprising a circulating circuit divided into two portions and leading from and to a source of supply, a pump within the circuit for circulating liquid throughboth portions ofthecircuit, anda valve communication with both portions' by the operation of which the flow through one portion is unimpeded and the liquid contained in the other portion of the circuit may be withdrawn.

2. A drink dispensing device comprising a circulating circuit divided into two portions andleading from and to a source of supply, said. circuit including a pump and a valve common toboth circuits, said valve being normally set to permit a flowvfrom the pump through both circuit portions back to the source of supply and adapted when operated toleave one circuit portion unimpeded and toopen the other portion to discharge remote from the source of supply.

3". Adrinkdispensing device comprising a circulating circuitdivided into two portions and leading from and to a source of supply, said circuit including a pump and a valve common-to both portions, ameasuring cylin derin communication with each portion, said valve having an inlet port, a pair of flow and return ports and a discharge port, said valve having an opelating lever which when in normal position directs the liquidfrom the pump through the flow and return ports, through themeasuring cylinders back to the source of'suppl y and when moved'into operating position directs the flow through one flow and return port and a measuring cylinder back to the source of supply and from the other measuring cylinder through the second flow and return port through the discharge port.

4. In a drink dispensing device having a valve and a pair of measuring cylinders through which liquid is normally, being circulated back to its source of supply, a valve common to both measuring cylinders-adapted' when turned into open position to leave the circulation unimpeded through one measuring cylinder and to discharge the contentsof the other through said valve, and means for recording the discharge from said cylinder.
