Patented Nov. v1942 UNITED sTATEs PATENT OFFICE mms y momma maures eorpotatlonof Maryland ma smut as. mo. seria N. :ma: z claims. (ci. sa-ss) This invention relates to refrigerating aD- paratus. n

One of the objects of my invention is to provide for supporting a receptacle below a refrigerant evaporator on a shelf and to arrange for guiding the receptacle when placed in position under the evaporator by depending the guiding structure from .the evaporator so that the receptacle will be placed in proper position. Another object of my invention is to utilize the aforesaid guiding structure for supporting a drip pan above the receptacle.

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

In the drawing: Y v

Fig. 1 is a fragmentary front elevational view of a refrigerator cabinet showing the invention applied with parts broken away and parts shown in section;

Fig. 2 is a fragmentary sectional view taken along line 2-2 of Fig. l;

Fig. 3 is an enlarged cross sectional view taken along line 3-3 of Fig. l;

Fig. 4 is an enlarged fragmentary Icross sectional view taken along line l-l of Fig. 3; and

Fig. 5 is an enlarged view taken along line 5-5 I of Fig. 2. y

Referring to the drawing, there is shown a refrigerator cabinet having a food storage compartment 22. through an opening which is closed by a swingably mounted door 2l. Suspended within the compartment is an evaporator 25. The evaporator is of well known type wherein is provided a freezing compartment to which access is had lthrough a hingedly mounted door l29, and the side walls of the evaporator are chilled by refrigerant flowing through passages provided therein for cooling the circulating air in the food storage compartment 22. 4

:Secured to and depending from the opposed side walls of the evaporator are guide and supf porting members and 32. The members 3B and 32 are ea'ch similarly formed preferably of Wire or bar stock bent in form of a U with the leg sections 34 secured by weld, solder or the like to a respective plate .36 that is riveted by rivet 31 "o to side wall of the evaporator. The

members

30 and 32 are thus secured to be in opposed parallel relation extending downwardly below the bottom of the evaporator and bent so as to extend outwardly beyond the side walls of the evaporator.

Access to the compartment isV Between the members Il and I2 is set a deep pan Il which rests preferably upon an imperforate shelf l2, though it will be obvious that an open bar or wire shelf may be used if desired. The shelf l2 extends across the full width of the compartmentand is supported on brackets I5 secured to and extending inwardly from the side walls of the compartment. The pan ll slides on the shelf 42. In sliding the pan outwardly from the compartment for the inspection of its contents, or retracting the pan into the compartment, it is guided between the parallel bight section 46 of members Il and 12.' The bight section 46 being so arranged as to contact the side wall of the pan and serve as guide rails.

Supported between the pan and the bottom of the evaporator 25 is a tray 50 of shallow depth for receiving the melted ice defrosted from the sides and bottom of the evaporator unit. The tray 50 is supported on parallel rods or bars 52 which extend between and joined to the leg sections -34 of

members

30 and 32. The parallel rods 52 are joined together by parallel rods 5l thereby for-ming a rectangular frame supporting base for the tray 50. The

frame members

52 and 54 are adapted to be received in grooves 55 formed in the bottom wall of tray ill and are formed to extend in identical pattern to the frame supporting baseformed by the rods 52 and 5l. 'l'hus by this arrangement the tray 50 can be quickly located into .position as the user merely need slide the tray onto the supporting frame until the grooves 56 coincide with the frame structure upon which the tray will drop into place. 'I'he tray 50 is fixedly held against any accidental lateral movement that could be caused during the removal or placing of articles on shelf I2 adjacent thereto.

To allow for a ready removal of the tra-y 50 the rearward edge of the parallel laterally extend- 0 ing grooves 5l (see Fig. 3) are sloped as at 60 to allow the rods 52 to ride out of the grooves to cause the tray to ride upwardly as it is drawn forwardly. One of the laterally extending grooves is provided with an abrupt forward edge 62 providing a stop against rearward movement as the tray is being retracted.

Rails or guides 55 extend between the parallel legs 34 of respective members III and l2. The rails |65 serve to guide and keep in alignment the tray 50 on its supporting frame.

In the above described arrangement there is thus provided a simple arrangement 4for the supporting of a defrosting tray from the evaporator unit. and means formed in the tray cooperating 55 with its supporting structure for iixedly holding thetray in n xed position, but allowing the tray to be easily and quickly removed whenever desired to remove the water accumulated therein.

While I have described the preferred form of my invention, I do not wish to limit myself to the precise details as shown but wish to avail mysel! of such variations and modiilcations as may come within the scope of the appended claims.

I claim:

-1. Refrigerating apparatuaomprising a :cabinet havlngva iood storage compartment, ay re frlgerant evaporator in said compartment, a shelf below said evaporator, a receptacle adapted to be placed on said shelf below said evaporator and means carried by said evaporator for yguiding said receptacle as it is placed on said shell;l and means carried by said first named means for supporting a drip pan above said receptacle and below said evaporator.

2. Refrigerating apparatus comprising a cabinet havingr a food storage compartment, a refrigerant evaporator in said compartment, a shelf below said evaporator. a receptacle adapted to be placed on said shelf below said evaporator, means carried by said evaporator for guiding said receptacle as it is placed on said shelf. and means carried by said nrst named means for supporting an imperforate member of substantially the same width and length as said receptacle above said receptacle and below said evaporator.
