This invention relates to refrigerating apparatus and more particularly to refrigerating apparatus of the water cooler type provided with a food or bottled beverage compartment.

An object of this invention is to provide a water cooler having a water cooling compart-. ment and a food or bottled beverage compartment in which both compartments are propw erly refrigerated by an expansion type of coil.,

Another object of this invention is to provide a water cooler having a water cooling compartment and a food or bottled beverage compartment so arranged that they may be readily cooled by a single sinuous expansion type refrigerating coil.

Another object of this invention is to provide a water cooler of the type hereinbefore no described which is adapted to receive water from a demijohn or the like.

Further objects and advantages of the present invention will be apparent from the fol lowing description, reference being had to the accompanying drawings, wherem a preferred form of the present invention is clearly shown.

In the drawings: Fig. 1 is a view, partly in elevation and partly in section, taken from the side of a water cooler embodying features of my invention.

Fig. 2 is a view similar to Fig. 1 taken at right angles to said Fig. 1.

Fig. 3is a perspective view of a water cooler embodying features of my invention.

Fig. 4 is a cross sectional view of a portion of a modified water cooler embodying features of my invention.

A water cooler embodying features of my invention may comprise a water cooling compartment designated as 20. It may also be provided with a food or bottled beverage compartment designated as 21. These .two compartments may be of substantially the same horizontal extent, having two dimen-.

sions substantially the same, and ma' be placed in alignment with each other. referably the water cooling compartment 20 is placed, above the food or beverage compart- 1928. Serial No. 289,548.

ment 21 in order to provide for the reception of a demijohn or the like designated as 22. The demijohn 22 may be supported on a suitable cover. Such cover may comprise a subplate 23 having an upwardly extending flange 24. An upper panel 25 may be provided with a downwardly directed flange 26 adapted to telescope with the flange 24 in order to form a passage for the reception of the neck of the demijohn. A gasket 27 may be provided for supporting the demijohn. The food or bottled beverage compartment 21 may be provided with a door 30 which may be hinged to a portion of the cabinet generally designated as 31. The compartment 21 may comprise a suitable enameled sheet metal compartment provided with a doorway opening 32. If desired, this doorway opening may be suitably trimmed by panels 33 in order to provide a door-jam having a finished appearance. The compartment 21 may be of a size sufficient to hold several bot-- tles of beverage or a small amount of food.

The Water cooling compartment 20 may be "provided with draft means such as a faucet 34c under which may be supported a drain pan 35 having a drain plug 36. The level of the water in the compartment 20 is automatically maintained in the well known manner. The construction. hereinbefore described is adapted to be cooled by an expansion coil generally designated as 37. This coil may be provided with an automatic expansion valve 38. If desired, the valve 38 may be made automatically responsive to the pressure in 3f the coil 37 The valve 38 is adapted to receive liquid refrigerant thru the pipe 39,

which may be supplied with liquid refrigerant from an automatic refrigerant liquefying unit placed in any convenient location, for instance, in the lower part of the cabinet 31. This refrigerant liquefying unit may be automatically operated by a thermostat placed in any desired location, for instance, near any desired portion of the coil 37. The refrigerant liquefying unit, if desired, may be of the compressor, condenser, liquid receiver type which may be operated by an electric motor automatically. started and stopped by a sna switch operated by the thermostat herein efore described.

The expansion coil 37 is adapted to be sinuonsly wound around the compartments and 21. In the preferred form the portion of the coil which is adjacent to the expansion valve 88, generally designated as 40, may be wound around the compartment 21. Another portion of the coil which is beyond the portion 40 may be wound around the compartment 20. This portion is designated as 11. The coil may then discharge thru the outlet pipe 42 to the refrigerant liquefying unit hereinbefore described. It is thus seen that the beverage 01' food compartment 21 receives the coldest portion of the expansion coil and that the water cooling compartment 20 receives a warmer portion. This arrangement is used when it is not desired to cool the water to an extremely low temperature and when it is desired to maintain the water at its most palatable temperature. The cabinet 31 may be of any suitable construction and may comprise a metal frame work having upright and horizontal angle irons to which outer sheet metal panels 51 may be secured in any desired manner. A wooden frame work 52 may be mounted to the top of the metal frame work 50 and a flange 53 may be provided in the water cooling compartment 20 which is adapted to rest on the wooden frame work 52. The subplate 23 may rest on the wooden frame work 52 or the flange 53. Insulation 5-1 may be provided for the compartments 20 and 21. This insulation may be made of any suitable material. For instance, it may be cork board or rock cork provided with a suitable recess for receiving the coil 37. The recess may be made to conform to the coil 37 or the insulation may be attached to the outer surface of the coil leaving an air space between the compartments 20 and 21 and the in sulation.

The coil 37 may be separate from the compartment 20 and 21 or it may be integral therewith. As shown in Fig. 4; the lining of the compartments 20a and 21a may be corrugated inwardly and a second lining may also be corrugated to correspond with the corrugations of the first named lining. These two linings may be telescoped to form an expansion coil integral with the compartments 20a and 2111. A partition plate 61 may be placed between the two compartments.

In either of the modifications the expansion coil may be wound around the food compartment in such a manner as to provide an opening for access into the compartment. As a specific embodiment, the coil may reverse itself after traveling partly around the compartment and may retrace its course around the compartment in a generally upward direction, thus forming loops 62 near the door opening. The coil, when it reaches the water cooling compartment, may be wound in the form of a continuous spiral in a generall upward direction. The insulation 54 may be of thesame type as that shown in Fig. 1. In general the other parts of the water cooler shown in Fig. 4 are the same as those shown in Figs. 1, 2 and 3.

While 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.

\Vhat is claimed is as follows:

1. A water cooler comprising a water cooling compartment adapted to receive a demijohn, a food compartment in alignment belowsaid water cooling compartment, an automatic refrigerant expansion valve, an expansion coil with its portion adjacent said expansion valve in thermal contact with said foot compartment and with another portion beyond said first named portion in contact with said water cooling compartment.

2. A water cooler comprising a water cooling reservoir and a food compartment arranged below said reservoir in a relatively long and narrow cabinet, an expansion coil provided with a long sinuous passage in thermal contact with an outer wall of said food compartment, and having another portion in contact with the water cooling reservoir.

In testimony whereof I hereto aflix my signature. 1 L
