o all whom if, may concern:

lle it known that I WILLIAM Il. WALTER, a citizen oi the United States, residing at Chicago, in the county oi' (look and State of Illinois, have invented new and useful Improvements in Liquid-Dispensing Mechanism, of which the following is a specification.

This invention is a coin operated machine for dispensing liquids, and comprises valve controlled means to measure and dispense the liquid. It is intended to be used in stores, cafs, and other public places for the purpose of dispensing liquids, and includes as an especial feature means for cooling the liquids so dispensed. It will serve to put within convenient reach oi all persons a cheap and cool drink, by a novel mechanical means to be hereinafter described.

In the accompanying drawings, Figure l is a vertical section of the device. Fig. 2 is a detail in section showing the valve passages. Fig. 3 is a detail in horizontal section on the line 3 -3 of Fig. 1.

Referring specifically to the drawings, 10 indicates an outer cylindrical casing which contains the coin operated valve mechanism and also the ice chamber through a coil in which the liquid is discharged. The valve operating mechanism and parts of the apparatus are contained in an upper chamber 11. The lower or ice chamber l2 is provided with an insulation 12* to retain the cold and serves as a rcirigerating chamber for cooling the liquid sold.

13 is a. reservoir, preferably a large glass bottle, which is inverted so that it discharges through the mouth 13.

This is mounted in an opening on top of the casing 10' with the neck oi the bottle extending through the opening and the shoulder oithe bottle resting on top of the casing. The mouth of the bottle projects into and is sealed in a trap vessel 14 in the upper chamber, and leading from the bottom oi this vessel is a tube 14* which is provided with a. controlling valve 18.

At .i6 are indicated two closed msuring cups, which determine the quantity of liquid supplied at cach operation, and these cups are respectively filled and discharged at each operation of the device, one cup being filled while the other is being emptied. Air tubes 15 connect the top of the cups with the vessel 14, so as to provide an air vent to allow the cups to fill and also to return any overfiow into the trap vessel 14. 'lhcse cups are connected by pipes 17 to the controlling valve 18, which is a four-way valve, as shown in Fig. 2, and is consequently operated by a quarter turn. The main discharge pipe i9 leads down from the valve into the refrigcrating chamber 12 at the bottom of which it is provided with a coil 19* which terminates in a discharge nozzle 19b which extends through the wall of the casing'in position to fill a glass on a bracket 19.

19d is a drainage tube having one branch extending tothe bracket and another brauch forming an overflow from the ice chamber with a half circle air trap 19 at the top. Leading into the main discharge. pipe 19 near the upper end thereof is an air vent pipe 32, forA the purpose of relieving the air or air pressure from the coil and assure a perfect delivery of the fluid. This air vent joins the pipe 9 on substantially a level with the nozzle 19".

The valve 18 may be operated `by any desirable or suitable coin mechanism. I have indicated such a mechanism, as a whole, at X. y

In the operation oi the device thecoin is deposited in a slot provided for the purpose, and by means of the coin mechanism referred to the valve is given a quarter turn. The coiland delivery pipe are first primed by filling the same with the liquid tothe level of the -discharge nozzle. When the vmechanism is actuated the liquid will flow from the bottle or reservoir through the pipe 14 and through one of the ports of the valve into one of the cups 11,6, filling said cup, and at the same time the other cup 16 will discharge through its outlet` pipe and the other port of the valve, Vinto the discharge pipe 19, as cloarlyshow'n in Fig. 2, causing a corresponding discharge from the delivery nozzle. At the next operation the respective cups are emptied and filled in a similar manner. There is thus always a charge or quantity of liquid to be delivered inthe cooling coil, where it remains until the device vis operated, and during which period it is effectively cooled,

I claim: i

In a liquid dispensing mechanism, in combination, a cn'sing having an upper: chamber and a lower refrigernting chamber, a liquid-reservoir comprising an inverted hottie the neck ot which extends through an opening in the top o! the casing, a trap vessel in the upper chamber, into which the mouth of the bottle extends, a four-way valve and its casing located in said upper chamber under the trap vessel, a pair of measuring cups located in the upper chamber and having pipe connections with the vnlvsfcasing and vent pipe connections trom the top thereof to the trap vessel, a pipe connecting the trap vessel and the valve casing, and a delivery pipe extending from the valve casing down through the retrigernting chamber and having a coil in the bottom of said chamber and a diselm" nozzle above the coil, whereby a quantity ot liquid is retained in the coil at alliimes, the valve being constructed to iili one measuring cup and empty the other at each operation.

In testimony whereof I have signed my name to this specication in the presence ot two subscribing witnesses.

WILLIAM II. WALTER.
