HODGS'ON, OF DAYTON,` OHIO, ASSIGNOBS T0 FBIGIDAIRECORPORATION, I' DAYTON, OHIO, A CORPORATION DELAWARE naariiroiiiiin'rme Primeros apparatus and more particularly to a Watei" cooling apparatus.

An object of-this invention is to provide a water cooler having a food or bottled beverage storage compartment as well as a water cooling compartment.

Another object 'of this invention is to provide a water cooler of the type herein-` before described in which proper temperatures are maintained in both compartments.

Another object of this invention is to provide a water cooler provided with a water compartment and a food or bottled beverage storage compartment and in which a cylindrical doet valve controlled evaporator may be placed so that it refrigerates properly both compartments separately.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of the invention is olearl shown.

ln. the drawings:

Fig. l is a view partly in elevation and partly in section taken from the front of a water cooler embodying features of our invention;

Fig. 2 is a view similar lto Fig. i taken substantially at right angles to llig. ki,

Fig. 3 is a view somewhat similar to Fig. 2 showing a modied form;

Fig. d is aview of a" portion of an apparatus shown in Fig. 3 in which a further modification is embodied; i

Fig. 5 is a diagrammatic view of a refrigerating system adapted to be used with a water cooler embodying.features of our invention, and Fig. o is a view in elevation partly broken away land showing a float valve controlled evaporator embodying features of the invention. l

' it; water cooler` embodying features of our invention may comprise a cabinet, generally designated as 20, which may be provided with a water cooling compartment, generally designated as 21, and a foo'd or bottled 1928. Serial No. 389,422.

beverage storage compartment generally designated as 22. lf the water cooler is to be supplied with water from a demijohn, the cover for thc water compartment may comprise a subplate 23 and a top panel 24, adapted to telescope at 25 to form means for supporting the demijohn 26 in an inverted position with its neck in the water cooling compartment. If desired, a suit? able gasket 27 may be provided to support the demijohn. The water com artment 2l may also be provided with raft means, such as a faucetp28, under which a drain receptacle 29 may be placed, whiclidrain receptacleI may be provided with a suitable drain valve 30 for emptying the drain receptacle. The drain receptacle 29 may be made as a separate tting and may be attached to the cabinet 20 by any suitable means such as by screws 3l.

In order to cool the water and the food or bottled beverage, a cooling unit 32 may be provided which has thermal contact with the water compartmentand with the food or bottled beverage compartment. As a speciic embodiment, the two compartments 2l and 22 may be provided with a common dividing wall 33 and the cooling unit 32 may be supported in contact with the dividing wall 33. As a further specic embodiment, the wall' 33 may be provided with a semi-cylindrical odset 34. The cooling unit y be a cylindrical boiler made of spun copper or brass or the like which is provided ,i

with a valve plate 35 for' supporting in the boiler 32 a suitable heat controlled valve 32a which controls the admission of liquid refri erant from the, pi e 36 into the boiler 32. he late 35 may a so be provided with a fitting 3 adapted to receive the evaporated refrigerant from the boiler 32 and to deliver it to a return pipe 38 which returns the refrigerant to a refrigerant liquefying unit hereinafter to be more fully described. The

cooling unit 32, when in the vform of a cylindrical boiler, may be supported rg inst the semi-cylindrical offset 34 by means of straps 39 which may be secured to the partition 33 by any suitable means, as by bolts 40. It is thus seen that the water in compartment 21 is cooled through the medium of the thermal contact of the cooling unit 32 with the wall 34 and that the compartment 22 is cooled by the direct contact of the cooling unit 32 with the air in the compartment 22. A suitable door 41 may be hinged to the cabinet 2O in order to permit access to the compartment 22. A suitable door jamb 42 may be-provided to receive the door livers compressed refrigerant through the pipe 51 to a condenser 52. The refrigerant condensed in the condenser 52 is delivered through the pipe 53 to a liquid refrigerant receiver 54. A pipe 36 extending below the normal level in the receiver 54 delivers liquid refrigerant to the cooling unit 32 Where the refrigerant is evaporated. The evaporated refri erant leaves the evaporator 32 through the tting 37 and returns to the compressor through the pipe 38 Where the refrigerant is compressed to repeat the cl cle. In order to render the operation of t e unit automatic, an automatic switch may be provided for starting and stopping the motor 55 which drives the compressor 50. For instance, a pipe 56 may be connected to the low pressure pipe 38 and may be also connected to an expansible bellows 57 which operates the snap switch 58 for starting and stopping the motor 55.

If desired, the food or beverage compartment may be placed above the Water compartment. For instance, as shown in Fig. 3, the cabinet 20a is provided at the top with a food or beverage compartment 22a under which there is placed the Water compartment 21a. In this particular embodiment, the Water may be supplied to the compartment 210, from the regular Water supply pipes. Thus, a water inlet pipe 60 may be provided for delivering water to the compartment 21a. A suitable bubbling cup 61 may also be connected to the compartment 21f1`-and the discharge of Water may be regulated by a suitable valve 62. A drain pipe 63 may be connected to,the drain pipe of the building in which the Water cooler is located and this ipe 63 receives the Waste Water from the bubbling cup 61. A suitable door 41a may be provided in the cabinet 20a.

The opening for access into the 4food or beverage compartment may be placed at the side of the cabinet as shown in Figs. 1, 2, and 3, or, if desired, it may be placed on top of the cabinet. As shown in Fig. L1- the top of the cabinet may be provided with a circular opening 65 and a lid 66 may be used for closing the opening. This lid 66, if desired, may be of the same type as is generally used for closing the ice cream containers in ice cream cabinets non1 in use.

It is thus seen that We have provided a. Water cooler which has a Water cooling compartment and a food or bottled beverage compartment in which food or bottled beverages may be placed and in which. an evaporator is located in thermal contact with both of said compartments in such a manner as' to insure the proper temperatures in both compartments. By using a cylindrical boiler with a removable plate 35, standard equipment may be used. The boiler 32 is some- What similar to the standard evaporators n ow in use and is adapted to use a standard float valve control plate 35 of the character noW generally in use. The other parts of the cabinet are adapted also to receive standards parts now in use for domestic mechanical refrigeration.

lVhile the form of embodiment of the invention as herein disclosed constitutes a preferred form, it is to be understood that other forms might be adopted, all coming Within the scope of the claims which follow.

What is claimed is as follows:

1. A Water cooler comprising a Water cooling compartment, a food storage compartment in alignment with said Water cooling compartment and having a common dividing wall, an evaporator in one of said compartments in Contact With said Wall.
