T 0 QZ? whom t may concern.'

Be it known. that l, lli/Trimmer. A. SCHATZ, a citizen of the United States, residing at Astoria, in the county of Queens and State of New York, have invented certain new and useful. li'nprovements in Beverage Dispensers, of which the following is a full, clear, andy exact description, suchas will enable others skilled in the art to which kit appertains to make and use the same.

rlhis invention relates to beverage dispensersv and more particularly to beverage dispensers having facilities for cooling and mixing liquids.

It is an object of the invention to provide a. beverage dispenser having simple and efficient means for cooling, evenly mixing, and dispensing a plurality of liquids.

It is a further object vof the invention to provide such a beverage dispenser comprising features 'of structural superiority and functional advantage. j

Other objects will be in part obvious and in part pointed out hereinafter in connection with the following description of the accompanying drawings, which illustrate a tvpical embodiment of the invention.

ln the drawings7 i A Fig. 1 is a vertical cross-section of the device;

Fig. 2 is a front elevation of the faucet member;

Fig. 3 is a vertical section of the faucet and adjacent parts; and

ld'ig. i is a fragmentary vertical crosssection of a modified form.

In the preferred embodiment of the invention illustrated, there is provided a con-- tainer 1, preferably transparent. mounted upon a cooling chamber 2.,v and communicating with a draw-olf faucet 5 b v means of a pipe or duct extending through the cool- `ing chamber. A. supply pipe 3 conveys water or other liquid under pressure to a coil of pipe 4 within the cooling chamber, also having direct connection to the faucet 5 in which the two liquids are automatically mixed. The chamber 2 may be cooled in any convenient manner as by packingwith ice, and a stop-cock (not shown) may be provided preferably above the level of the coiled pipe for draining oif water from the cooling chamber.` In` operation, when the faucet is opened, water under pressure is caused-to flow through the coil i and faucet 5.

into the faucet, and 'syrup from` the container is also admitted to the faucet. The twi'o liquids are forcibly and thoroughly mixed within thefaucet as will be described in detail hereinafter, and themixture then flows out through the nozzle 7 into a .suitable receiver.

The container 1, in the form shown, is provided with an extension or neck' 8, which is adapted to be seated in a cup-like part 9 depending from a supporting part*`10lv ofy the cooling chamber. A tight joint between the container and its support may be insured by allo-wing anenlarged portion of the neck 8 to rest on a rubber ring 11 held by the fixed supporting part.` ri. pipe 12 in free communication with the neck 8 of the container is sealed through the bottom of the cup 9 and leads directly to the The container 1 may have kan opening at the top for filling and is preferably provided with a covervpart 13. 'As

shown clearly in Fig. 1 the neck 8 of the container 1, the cup `9 and the pipe 12 will normallyy be filled with liquid .from the container, thus allowing considerable cooling effect to be realized from the encasing cooling chamber. K' The liquid in the coild and in the pipe 13 leading therefrom 'to the faucet will be thoroughly chilled in a similar manner. The walls 1li of the chamber y2 may be packedwith any poorly conducting substance, such as fiber, to keep the temperature within'the chamber as low as possible. As shown more in detail in Figs. 2 and 3, the faucet 5 comprises a slightly tapering shell 15 forming a combined mixing chamber and valve Within which is attached a tube 16, which may be vertically adjustable so as to transect more or less of the space within said shell. The tube 16 closes the opening at the lower end of the shell 15, rbut an annular vspace is left within the shell around the tube Ifurther up along its length, The member 15 'is seated in a correspondingly tapered supporting part 17 lfixed* upon the neck 18 -through. which the pipes 12 and 13 lead to ythe faucet. iport 19 registering with the pipes 12 and 13 ,when the faucet is turned to operative posi- The wall 15 is provided with a tion, as shown in Fig.` 3. 'In this position waterunder pressure allowed to `enter`the mixing chamber ofthe faucet throughk the pipe 13, is met by the wall of the tub'eflG, which acts as a sort of baffle, andis forced to liquid in the container.

flow around the tube andupwardly in part past the mouth of the pipe 12 before entering the tube through its upper end 2O and being discharged through the nozzle 7. By such a course sucti'onis created at the mouth of the pipe 12 and syrup passes in a steady even flow through this pipe into the mixing chamber. In operative position, the upper end of the tube 16 is preferably on a level with the mouthof the upper supply pipe 12, or above that level., and the discharge opening through the tube is preferably considerably larger than those through the supply pipes, so that there will be no tendency for the liquid to back up through the supply pipe 12, after entering the mixing chamber under pressure through the supply pipe 13. Such a tendency is further counteracted, in the form illustrated, by the pressure already existing at the mouth of pipe 12 due to the head of The thoroughness ofthe mixing may be varied to some extent by adjustment of the tubular member 16, so as to vary the capacity of the mixing chamber. It has been found that by the construction described a very thorough and iu- .timate mixing of the liquids is assiu'cd. The course of the liquid is altered and in part actually reversed in direction after entering the faucet and by this breaking up of the flow the two liquids are thrown together in such a way as to insure thorough intermingling.

If it is desired to draw oif one of the liquids in a clear state, the faucet handle is turned so that a port 21 which registers with but one supply pipe 13 admits but one of the liquids into the faucet. Obviously, the construction may be modified to admit other liquids and allow various combinations thereof. A screw plug 22 may be provided to protect the flow of lsyrup through the pipe 12 and thus regulate the mixture when a lesser quantity of any particular liquid is desired.

In the closed position as shown in Fig. 1 when the faucet handle is at right angles to the direction of flow of the entering liquids, an imperforate portion of the wall of the faucet closes the mouths of the tubes 12 and 13. When a mixed beverage is desired, a quarter turn of the handle in one direction allows entrance to liquids from both supply pipes and the two liquids are suddenly and forcibly intermingled in the very process of being discharged. From the original closed position a quarter turn of the faucet handle inthe reverse direction results in the flow of one liquid clear. Thus substantial and eificient means for accomplishing the objects of the invention are provided and the operation thereof is simple and easy.

A modified form of connection between the bottle and the cooling chamber is illustrated in Fig. 4. In lthis construction a metal ring 23 is permanently fixed upon a -flanged portion 24 of the neck of the container as shown and is adapted to be attached as by a screw thread connection to a cooperating ring 25 on the supporting member 10. Then the parts are assembled the lower edge of the neck 24 is seated on the ring 11, held by the member 25 and the-receiving cup 2G, and the container is thus tightly but removably secured in position.

As many further changes might be made in the above construction without departing from the spirit and scope of the invention or sacrificing any of its advantages, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

lt is also to be understood that the lan guage used inthe following claims is intended to cover all the generic and specific features of the invention herein described,
