(01. 62—141) My invention relates to liquid cooling appara- the machinery compartment l2. A cooling ele-‘ tus, and particularly to a combined =bottled beverage cooler and draft liquid cooler. ' ment I1 is disposed in the refrigerated compart ' ment I3. It is an’ object of my invention to provide a 5 draft liquid cooler for a bottled beverage cooler which may be supplied as original equipment with the bottled beverage cooler, or may be utilized to convert existing bottled beverage coolers liquid cooler generally designated at 22. > to combination bottled beverage coolers and 10 draft liquid coolers. It vide ated able - ' is another object of my invention to proa draft liquid cooler for use in a refrigercabinet, wherein the draft liquid is availat an accessible portion of the exterior of 15 the cabinet, which cooler, including a container for the liquid to be cooled, a faucet, and a pipe connection between the faucet and the container, is removable from the cabinet as a unit, without disconnecting the faucet or pipe, connection. 20 It is a further object of my invention to pro- The refrigerated compartment I3 is provided with an upper access opening I8, a por tion of which is covered by a hinged closure I9. 5 The remainder of the access opening is covered by a removable supporting plate 2| for a draft ' .Referring to Figs. 2, 3, and 4, the draft liquid , cooler 22 comprises a faucet 23 on the top of 10 plate 2| connected to a supply of liquid by a con duit 24. The faucet is also connected by a con duit 25 to a coil or cooling vessel-26, which coil or cooling vessel is in turn connected through .a ' conduit 28 to outlet 21 on the top of plate 2|. 16 A pressure regulating valve 29 is connectedbe- ' tween the faucet 23 and coil 26 in the conduit 25.v A drain conduit 3| is provided adjacent the out-_ let 21. The drain conduit 3| extends into a funnel shaped conduit 3|a which catches drain 20 vide a draft liquid cooler for a bottled beverage . water. A drain conduit 32 is attached to the cabinet, in which heat is abstracted from the funnel 3|a and extends to the exterior of the bottled beverage bath, and wherein the draft liq-_ cabinet ||. uid ‘cooler is partially immersed in the bath so 25 that heat is also abstracted from the draft liquid. ' ' ‘ The refrigerated compartment I3 is preferably ?lled (with a sweet water bath, indicated at 30, 25 It is still a further object of my invention to > which bath is cooled by the cooling element I1 I provide a draft liquid cooler from whichfheat may be‘ abstracted by mechanical refrigeration, which draft cooler is readily removable from the 30 cabinet containing the draft liquid cooler'with' out disturbing the refrigerant connections of the refrigeration system. , _ These and other objects are effected by my invention as will be apparent from the following 35 description and claims taken in connection with the accompanying drawings, forming a part of this application, in which: .Fig. 1 is a perspective view of a cabinet containing a bottled beverage cooler and a draft 4'() liquid cooler; Fig. v2 is a sectional elevation of the cabinet shown in Fig. 1; Fig. 3 is a bottom view of my draft liquid cooler; and, 45 . ' _ of the refrigerating system. Bottled beverages ' are immersed in the bath 30 for cooling, access being obtained to the bottled beverages through the hinged closure member. IS. The coil 26 is 30 also immersed in the cooled sweet water bath 30 so that heat is abstracted from the draft liquid passing through the coil 26. q . The draft liquid cooler 22 may be removed as a unit from the cabinet H by disconnecting only 35 the supply conduit 24, and a suitable union 33 is provided for this purpose at the exterior of thecabinet ||. The draft liquid cooler 22 may be supplied with the cabinet ‘II as original equip ment, or bottled beverage cooler ‘cabinets may 40 be converted to combination bottled beverage and draft liquid coolers by providing a closure means H! as shown in Figs. 1 and 2 and utilizing the supporting plate 2| to cover the remainder of the Fig. 4 is a sectional view of the draft liquid cooler taken on line II-II of Fig. 3 when looking access opening l8. Since the draft liquid cooler 45 22 is a unitary assembly, all that is necessary to in the direction of the arrows. Referring speci?cally to the drawings for a detailed description of my invention, Figs..1 and motor-compressor unit M, a condensing element convert a bottled beverage cabinet into a com bined bottled beverage and draft liquid cooler is to change the closure and provide supply and _ drain connections to the draft liquid cooler. Fur- 50 thermore, since the draft liquid cooler is remov able and replaceable as a unit, it is an easy mat ter to replace or repair the draft liquid cooler. From the foregoing, it will be apparent that I 55 I5, and'a distributing valve I6 are disposed in have provided a bottled beverage cabinet which 55 50 2 illustrate a cooling cabinet generally designated at H. The cabinet H is divided into a machinery compartment l2 and a refrigerated compartment I3 by a heat insulated partition Ill. . _A 2 2,130,515 may be provided with a novel draft liquid cooler said cover for abstracting heat from said chamber, a cooling vessel for draft liquid inserted, at least, in part of said chamber, and inlet and outlet connections for said cooling vessel extending through and attached to said cover, said cover and 6 exteriorly of the cabinet. No refrigerant or gas _ draft liquid cooling vessel being removable from at minimum expense, and which draftv liquid cooler is removable and replaceable by merely making or breaking liquid supply connection. In addition, the draft liquid is readily ‘accessible connections need be broken in removing or re placing the draft liquid cooler, and, therefore, the dangers of escaping refrigerant or loss of charge from ‘the refrigerating machine are , avoided. While I have shown my invention in but one form, it will be obvious to those skilled in the art said cabinet as a unitary structure when the in let- connection to said draft liquid cooling vessel is disconnected, and without affecting said cool ing coil. 10 5. In a liquid cooler, the combination of an insulated cabinet having a removable cover, a container for a liquid bath in said cabinet, a re that it is not so limited, but is susceptible of . frigerating system having connected thereto a 15 various changes and modi?cations without de cooling coil for abstracting heat from said con 15 20 parting from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art tainer, said cooling coil being disposed in said liquid bath independently of said cover, a draft liquid-cooling vessel attached to and depending or as are speci?cally set forth in the appended from the cover and inserted, at least in part, in the refrigerated container, a draft liquid inlet connection for said cooler extending through and claims. ~‘ ‘ What I claim is: 1.
