I REFRIGERATING APPARATUS Filed Feb. 28, 1950 3, INVEQTOR BY 7 M Mfl ATTORNEY Patented Dec. 22, 1931 UNITED STATES PATENT OFFICE FRANCIS E. STEVENSON, OF DAYTON, OHIO, ASSIGNOR 'I'O FRIGIDAIBE CORPORATION, OF DAYTON, OHIO, A CORPORATION OF DELAWARE BEFBIGERATIN G APPARATUS Application filed February 28, 1930. Serial 170. 4324196..

This invention relates to refrigerating apparatus, and more particularly to a shelf construction for refrigerator cabinets embodying refrigerating apparatus.

For one of its objects, this invention contemplates an improved shelf structure for refrigerator cabinets. More particularly to provide an improved shelf structure which will make available heretofore wasted space within the cabinet in the vicinity of the cooling unit.

A further object of this invention is to provide a stepped shelf arrangement for a refrigerator cabinet, one surface of which will serve asmeans for supporting the drip pan below the evaporator or cooling unit, which surface will also provide means for supporting an additional shelf, for utilizing the space within the cabinet in the vicinity of the cooling unit, which has heretofore been wasted.

.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 present invention'is clearly shown.

In the drawings:

Fig. 1 is a front view of a refrigerator cabinet with the door open, embodymg features of my invention;

Fig. 2 is an enlarged view of the shelf arrangement of Fig. 1, and

Fig. 3 is a view in section on the line 3-3 of Fi 1, showing the door in closed position.

Re erring. to the drawings, I have shown my improved shelf arrangement, generally ,designated by the reference character 10 as embodid'in a refrigerator cabinet 11, including an upper refrigerated food compartment 12, and a lower machine compartment 13.

An evaporator 14 is located within the food compartment 12, and is connected by means of conduits, not shown, to'a heat dissipating element locatedwithin themachine compartment 13. The heat dissipatingelement may be a compressor-condenser unit for example, or it may be the ordinary absorption apparatus. The evaporator 14,otherwise known as a cooling unit, may be any of the well known evaporators now in use. For exam- 22. The upper of the at is located just below the cooling unit ple, it may be similar to the evaporator disclosedjn the patent to R. G. Osborn, 1,556,--

708, patented October 3, 1925'. The food compartment 12 is provided with an opening in I its front wall which is closed by a closure member 15, while the machine compartment is provided with a door member 16in its front wall. V

Heretofore, in refrigerator cabinets, ithas been customary to provide a plurality of substantially fiat horizontal shelves within the food compartment similar to the shelf 16 for instance. The use of such shelves, however,

' at the same time will provide means for supportingthe drip pan 17 below the cooling unit. To this end, I provide the shelf 18 which is provided with a plurality of substantially flat horizontal surfaces 19 and 20, attached to the side walls of the cabinet at different vertical heights as shown at 21 and flat surfaces indicated 14 and provides means for supporting the drip pan 17 beneath the cooling unit. This section 20 is also provided with a groove 24 in which groove fits the downwardly turned edge 25 of the second shelf 26. The second shelf is provided with a substantially flat supporting surface 27 attached to the side wall of the refrigerator cabinet, as at 28,. above the bottom of the evaporator 14. t

It will be noted that by providing the stepped shelf arrangement- 18, and by sup-' porting the second shelf 26'on the uppersurface 20 of the shelf 18, that I am enabled to take advantage and to utilize the s ace ad jacent the top of the evaporator. urther,

this shelf arrangement provides for three supporting surfaces for provisions, whereas heretofore, only two-such surfaces have been provided. 1
