Serial 110. 391,145.

This invention relates to refrigerators, the principal object being the provision of a novel liquid cooler having means to cool liq uids in bulk and also in bottle form.

Another object is the provision of a mechanically cooled refrigerator having a refrigerated compartment therein, said compartment having a bulk liquid cooling container permanently mounted therein and provided with means for the support of an in verted bottle thereabove, and said compartment being further adapted to receive bottled liquids to be cooled.

Another object is to provide in a refrigerator cabinet having a compartment provided with a permanent water cooling con-. tainer therein and occupying only a portion of said compartment, a novel arrangement of a cooling element in said compartment for cooling both the water container and the remaining space in said compartment in which bottled liquids are adapted to be received, and further, a novel arrangement by which the relative degree of cooling of the water container with respect to the remaining space in the compartment mav be easily and simply varied.

Another object is the provision in the refrigerator cabinet of a hinged door adapted to swing downwardly and outwardly to a substantially horizontal open position in which it may serve as a shelf.

Another object is to form such a door with a marginal interior projection serving as a rail to prevent articles supported by the door when in its horizontal open position from slipping 01f.

, Another object is to detachably mount upon the outside of a refrigerator cabinet 9. container for receiving drippings from a dis-,

pensing valve Another ob]ect is to provide certain novel I features of construction that will be specifithen claimed, having the above and other obects in view.

In the accompanying drawings which illustrate a suitable embodiment of the present invention, and in which like numerals refer to like parts throughout the several different v1ews,

Fig. 1 is a front view of a refrigerator partly in section for better illustration.

Fig. 2 is a partially broken side view of the refrigerator shown in Fig. 1, including optional additional details but omitting the bodies of drawers and showing the horizontal open position of the hinged door in dotted lines.

Fig. 3 is a fragmentary sectional view of the upper portion of Fig. 1 showing how the insulation at the top of the cooling coils may be changed to vary the degree of refrigeration of the water cooler and a refrigerated storage compartment.

It is customary in the conventional types of refrigerator constructions to provide one refrigerator for cooling water or other liquids in the bulk separately, or one refrigerator for coolin'gbottled liquids or other articles separately. erator has been provided to serve the doub e purpose of cooling water or other liquids in the bulk and also providing a refrigerated compartment for cooling bottled liquids. In accordance with the present invention, I have provided ,a novel liquid cooling cabinet by equipping an upper chamber not only with a special major compartment containing a bottled cooling compartment all being combined in a construction adapted fully to utilize the maximum heat absorbing capacity of the cooling element.

As illustrative of the present invention I have shown in the drawings a refrigerator cabinet comprising a subdividedupper chamber 10 and a lower chamber 11. The lower chamber 11 is provided for installation of the usual refrigerating mechanism (not shown) to be used for operating a cooling element in theupper chamber 10. The elements shown in the subdividedupper chamber 10 comprise a removable or other per- As far as I know, no refri manentliquid cooling container 12, abrine tank 13 in a major compartment thereof, this being separated by special walls or baflles from a refrigerated compartment 14 for bottled liquids. Thebrine tank 13 is disposed in the lower portion of theupper chamber 10 and on one side thereof. Thecontainer 12 is shown as provided with a cover adapting it to receive a bottle neck and as disposed above thebrine tank 13 1n the upper portion of thechamber 10; and a movable neck-receiving cover element may extend entirely over theupper chamber 10. Avertlcally extending baflle 16 may be provided in I spaced relation to thebrine tank 13, when the latter is separately formed, as shown in Fig. 1; and it may have an upwardly and laterally extendin angularly disposed baflle 17 extending rom its upper edge to the top of thechamber 10 in spaced relation with respect to the angularly disposed. side of thewater container 12, saidbafiles 16 and 17 closing off the major compartment containing thebrine tank 13 and thewater tank 12 from the remaining or minor compartment 14 of thecabinet 10 adjacent thecontainer 12 as at 18'.

A sheet ofinsulating material 19 may be provided between the bafile 17 and the coils 18' in order that thecontainer 12 may receive a greater cooling effect from thecoils 18 than the compartment 14. This type of installation is particularly suitable wherea consider-' able amount of water or other liquid is disnsed.

A modified form of construction is shown in Fig. 3 in which theinsulating material 19 is disposed between thecooling coils 18 and the adjacent side of the'bottle-receiving element orcontainer 12. In this installation the refrigerating chamber 14 receives the greater cooling effect from the cooling coils 18' because of the disposition of theinsulating material 19 adjacent thecontainer 12.

Theusual pockets 25 are provided in thebrine tank 13 to receivefreezing trays 26. Each of thefreezing trays 26 is preferably provided with a flange 27 for cooperatin with a vertically extendingbafiie 29 dispose in the forward part of thechamber 10 which is provided for completing or concealing the brine tank its use providin better circulation of air around therine tank 13.Handles 28 are also provided for moving the tra s 26.

door 30 in front of thechamber 10 gives access to the chamber and is hinged. at its lower edge by a laterally extending hinge 31. Thedoor 30 is provided with interior mar- 'nal shoulders 32, formed by reversely bend other articles put thereon from falling off when thedoor 30 is swun into a horizontal position and used as a shelA folding brace 33 is preferably attached to the side of thechamber 10 and to thedoor 30 for holding the door when in its horizontal position. When thedoor 30 is in a horizontal position as shown in dotted lines in Fig. 2, it serves as a shelf.Insulatin material 51, such as rubber, is used arena the edges where thedoor 30 seats to prevent the transfer of heat to thechamber 10 from the outside of the cabinet.

Mounted on the top of the refrigerator cabinet is a separately replaceable outer bottle orother vessel 35 preferably used for water and preferably having the nature of a large inverted bottle, the shoulder of whichsets freely upon apackin ring 36 of rublines acircular opening 37 centrally provided in the movable or other cover element or top of the refrigerating cabinet and extending into thecontainer 12. Thus the neck of the said bottle is adapted to project into thecontainer 12. Suitably connected to the bottom of thecontainer 12 is adischarge pipe 38 which leads through the front wall of the refrigerator cabinet and connects. exteriorly of said wall with a normally closed control valve 39. Suflicient liquid will dischargefrom thecontainer 35 into thecontainer 12 to maintain in the latter a level such as to seal the mouth of said'container, and any-withdrawal of the contents of said container 12 n will permit a sufficient discharge from the container, 35 to re-establish such level. 'Any other inlet connection which permits operation in the general manner described may be attachedtothe container 12 toserve th same purpose as thebottle 35.

Supported on the front lower portion of.

the refrigerator cabinet is adrainage receiver 41 directly below the valve 39 for receiving the drippings therefrom or for receiving any liquid that is spilled. To support said receiver'for ready removal from the refrigerator an opening 42' is centrally formed in the top portion of the rear wall of thereceiver 41 and the metal displaced from said opening is upwardly bent to form ahook 43 adapted to fit upon correspondingly hooked bracket 44'exteriorly secured to the refrigerator cabinet and projectingthroughsaid opening 42.. Thereceiver 41 therefore can be easily removed to permit emptying of its contents. A screen or other member erably disposed within the top portion of thereceiver 41 uponsuitable brackets 46 to pre- Louvers 47 are disposed around the bot" tom portion of the refrigerator cabinet in the conventional manner for circulation of;

45 having suitable openings therein is prefair in the lower chamber 11 containing the refrigerating mechanism.

In the above described arrangement the liquid in thecontainer 12 is kept coolat all times and the compartment for keeping bottled liquids is likewise kept cool at all times. This device may be used in homes or business places generally, but it is particularly adapted for use in. restaurants and clubs. Thedrainage receiver 41 provides a simple means for catching the ,drippings and keeps the floor around the device clean. The horizontally extending door is another advantage which this refrigerator providesJin that hot tles, glasses, or. any other articles being put into the refrigerator or being taken out there from can be set thereon. It will be apparent that the above described device provides a means for dispensing low temperature water or other liquids, means to use a conventional type of bottle in cooperation with the container, means for obtaining ice, and a chamber for cooling bottled liquids.

It will be apparent that although thecontainer 12 is preferablv removable for cleaning or repair, it is in one sense a permanent part of the device, and this is the sense that the word permanent is to be interpreted in the following claims, and as opposed to a bottle or other container which it is necessary to remove in order to obtain the liquid contained therein.

Formal changes may be made in the specific embodiment of the invention described without departing from the spirit or substance of the broad invention, the scope of which is commensurate with the appended claims.
