E. O. STOUT REFRIGERATING APPARATUS 7 Filed NOV. 26. 1928 Patented Dec. 3, 1929 UNIED STATES PATENT OFFICE ELMER O. STOUT, OF DAYTON, OHIO, ASSIGNOR TO FRIGIDAIRE CORPORATION, OF DAY- TON, OHIO, A CORPORATION OF .'DELAWARE BEFRIGERATING APPARATUS Application filed November 26, 1928. Serial No. 321,782.

lhis invention relates to refrigerating apparatus or more particularly to an attachment for a mechanical refrigerating cabinet, which attachment is adapted to cool water for drinking purposes or the like.

An object of this invention is to provide an attachment adapted to be placed underneath or adjacent the cooling unit of a mechanical refrigerating cabinet, which attachment is adapted to cool water for drinking purposes or the like.

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

In the drawings:

Fig. 1 is a vertical cross sectional view of a refrigerating apparatus embodying features of this invention;

Fig. 2 is a top plan view of the attachment with parts broken away;

Fig. Sis an end view of Fig. 2; and

Fig. 4 is an enlarged cross sectional v1ew taken along the line 44 of Fig. 2.

A refrigerating apparatus embodying features of this invention may comprisea cabinet generally designated as 20. Within this cabinet may be placed a mechanical refrigerated cooling unit, not shown. This cooling unit may be placed within the cooling unit compartment 21 which is adapted to have an air inlet opening 22 and an air outlet opening 23. The cooling unit may be of any type desired and may forinstance lill be of the type shown in the patent to R. G. Osborn 1,556,708 patented Oct. 13, 1925. The cold air outlet 23 may be provided with a bafile 24 if desired. The refrigerant may be supplied to the cooling unit by means of an automatically actuated refrigerant liquefying unit which may be placed in any convenient place and may be constructed in accordance with the disclosure in the patent to Bechtold et al, 1,478,421, patented December 25, 1923. The air temperatures maintained adjacent the outlet. 23 are generally between 40 F. to F.

An attachment for cooling drinking water and the like may be provided. The attachment may be of the character shown at 30. If desired, it may be placed underneath theair outlet 23 and, conveniently, it may besuspended by means of a bar 31 attached to a beam like member 32. The water cooling unit may include a plurality of elongated closed tanks 33, and, if desired, they may be placed in a substantially parallel relation. The capacity of the water cooling unit 30 may be such that, under ordinary household requirements the amount of water withdrawn does not exceed the said capacity in volume. It is thus insured that water is always on tap at temperatures between 40 F. and 50 F., the most palatable temperatures. This temperature is substantially the same as the temperatures maintained underneath the cooling unit which is placed in compartment 21.

A pipe 34 may be placed at each end of the water cooling unit 30. The pipes 34 are adapted to pass completely into and out of each of the. ends of the tanks 33. At least one opening 35 is placed in the pipes 34 within each of the tanks 33. Closing means 36 are placed between some of the tanks in the pipes 34. Preferably the closing means 36 may be made by pinching the pipe together. Also, if desired, the closing means 36 are placed between alternate pairs of tanks so that thewater if it enters at the inlet 37 passes into the first tank 33 and then passes in a zig-zag course'into the pipe designated as 34* from whence the water passes into the tank designated as 33 from whence it passes to the pipe 34 and from thence into the tank designated as 33 and back to the pipe 34 and from thence into the last tank 33 to the outlet 38. The ends of the pipe 34 may be closed as designated at 39 preferably by inching the ends of the pipe together and, 1 necessary, by soldering,

the ends.

When the water cooling unit is placed in the cabinet, water may be supplied from any desired source. For instance, the pipe 40 may lead from the usual house water supply system or from a bottle supply. The pipe 40 may be connected by a fitting 41 to the water inlet 37 of the water cooling unit 30, heretofore described. The water outlet 38 may be connected to a pipe 42 by means of a fitting 43. The pipe 42 may be provided with a faucet 45 conveniently placed outside of the cabinet 20. If desired, a drain 44 maybe placed to catch the waste water from the faucet 45 or .for the purpose of holding the tumbler ready for use.

In constructing the water cooling unit the tanks 33 may be spun brass cylindrical cups closed at the ends and telescoping at the

ends

51 and 52 where they may be soldered together. Near the ends 50 openings 53 may be made in the tanks 33, and these openings may be drawn so as to provide flanges 54 which may be inwardly directed if desired. The

pipes 34 may then be forced through the openings 53 with the openings 35 in proper position, after which thepipes 34 may be soldered as at 55 to the pipe 34 in order to provide a rigid construction. The flanges 54 give a better surface condition for providing a thorough soldered joint between the tanks 33 and the pipe 34. The closures 36 may be made after the pipes 34 have been inserted through the tanks 33.

The rod 31 may be attached to the water cooling unit in any desired manner and for instance the bar may support the water cooling unit 30 on the underside. If necessary the bar 60 may be soldered to the water cooling unit 30.

It is thus seen that a water cooling unit of extreme simplicity and of very rigid character is provided.

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.
