Patented Nov. 10, 1953 SHELF AND CONTAINER FOR REFRIG- ERATOR CABINETS Floyd R. Eck, Des Plaines, Ill., assignor to Motors Products Corporation, Detroit, Mich., a corporation of New York Application July 16, 1951, Serial No. 237,017

13 Claims. "(01. 257-3) This invention relates generally to refrigerator cabinets of the type having a door and a refrigerated compartment.

It is an object of this invention to locate within the refrigerated compartment of the cabinet a container having provision for maintaining the contents thereof at a predetermined temperature above that existing within the refrigerated compartment. Thus for example butter may be maintained at the preferred spreading temperature even though the temperature within the refrigerated compartment is maintained far below the spreading temperature.

It is another object of this invention to support the container on a shelf having an inverted substantially U-shaped portion for receiving the container and having horizontal portions on which articles to be cooled may be supported.

It isstill another object of this invention to provide an upstanding wall at the front edge of the shelf having an opening providing clearance for the closure of the container and constructed to serve as a retainer to maintain articles on the shelf. 7

It is a further object of this invention to support the shelf on the inner door panel which may be bowed in a direction toward the outer panel of the door to provide a recess for receiving at least a portion of the shelf.

It is a still further object of the invention to provide a shelf of the above general type molded or otherwise produced in one piece from a suitable plastic, for example.

It is another object of this invention to removably support the container within the inverted U-shaped portion of the shelf on the inner door panel in a manner such that air in the refrigerated compartment may pass upwardly through the open bottom of the U-shaped portion and circulate around the container.

It is still a further object of this invention to support a thermostatically controlled heater and regulating means therefor on the bottom wall of the container.

The foregoing as well as other objects will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Figure 1 is a fragmentary front elevational view of a refrigerator cabinet structure showing the door in its open position;

Figure 2 is a sectional view takenon the line 2-2 of F gu 1;

Figure 3;

Figure 8 is a perspective view of the closure provided for the access opening in the butter conditioner or container; and

Figure 9 is a sectional view taken substantially on the plane indicated by the line 9-9 of Figure 3.

The numeral H) in Figure 1 of the drawings indicates a part of a refrigerator cabinet having a storage compartment I I and an evaporator I2 supported within the compartment II adjacent the top of the latter in a position to cool air circulating within the compartment II. Refrigerant is supplied to the evaporator I2 by apparatus well known in the art, and not shown herein. The cabinet I 0 has an access opening in the front wall and a door I 3 is hinged at one side edge to the cabinet for closing the access opening. As shown in Figure 2 of the drawings the door I3has an outer panel I4, an inner panel I5 spaced laterally from the outer panel, and

heat insulating material I6 housed within the space between the panels. The inner panel I5 is preferably formed of a plastic heat insulating material, and is embossed in a direction toward the outer panel I4 to form a recess [1 having a width approximating the width of the door I3 and having a length approximating the length of the door.

Supported within the refrigerated compartment II at a convenient elevation is a shelf [8 and a closed container I 9. The shelf I 8 is molded or otherwise formed in one piece from a suitable plastic material, and the container I 9 is preferably formed of sheet metal.

As shown particularly in Figures 2 and 9 of the drawings, the shelf l8 has an inverted substantially U-shaped portion 20 intermediate the ends thereof and has horizontal article support ing portions 2| extending laterally from the bottom edges of opposite side walls 22 of the inverted U-shaped portion 20. It will be noted from Figure 1 of the drawings that the shelf portions 2| are turned downwardly along the rear edges thereof to provide reinforcing flanges 23, and the latter are connected at spaced points to the undersides of the shelf portions 2| by transversely extending reinforcing ribs 24. A wall 25 extends upwardly from the front edge of the shelf l8, and the central part of this wall has a height approximating the height of the U- shaped portion 20. The portions of the wall 25 at opposite sides of the inverted U-shaped portion 20 form retainer rails 26 which serve to hold articles in placeon the shelf portion 2.l and are reduced somewhat in height at opposite ends of the shelf l8, as clearly shown in Figure 1 of the drawings. The bottom of the shelf I8 between the opposite side walls 22 of the inverted U- shaped portion is open to permit free passage of air into the U-shaped portion 20, and the front wall 25 of the shelf has r pening 2'] there through in registration with thefront side of the U-shaped portion 20.

The container 13 has an access opening 28 through the front wall and is provided with top, side, bottom and rear walls 29, 30, 3| are? spectively. The top wa1l'29 is shown in Figure 3 ofeihe win a eehhee ei is ih ieer wall tyatuiedsbnon"as, and the b ottgm wall 131 is m s e izhevi e sh 1 E edieie 's "eh'eh he 2h.

The thermostatically controlled heating element M is regulated to obtain various predetermined temperature within the container I9 by a thermostat 48. As shown in Figure 6 of the drawings the housing 49 of the thermostat 5;; has lateral f langesiil q which is engageable with'the front side of the flange 4 :6 of the bracket 42, and has openings 50 at opposite ends respectively registering with suitable buttons '5! em- .ZOXLS i5! project into the openings 50 and the two plates are held in this position by spring plipsgz. {lheclips fl are generally U-shaped ,ooristr uctiqn and respectively straddle oppositeedges of the flanges 49' and flange 46 to prevent accidentalflisengagement of the latter.

For securing the shelf to the door a plurality of projections are formed on the rear side of the shelf, and these projections extend through registering openings in the inner door panel 15., Suitable friction nuts 68 cooperate with the projections 61' to rigidly clamp the shelf [8 in place.

When the shelf l8, together with the container, is mounted on the inner panel N5 of the door, it will be noted that the rear wall 32 of the container is spaced some distance from the inner door panel 15. Also the top and side walls of the container 19 are respectively spaced laterally from the top and side walls of the inverted U-shaped portion 20. As pointed out above the bottom of the shelf is open below the inverted U-shaped portion 28 so that refrigerated air in the storage compartment may circulate over the walls of the container 19.

In order to protect the electrical terminals employed for the heating unit 4|, a plate is secured to the inner door panel l5 directly below the container l9. It will be noted from Figure 9 that the plate (0 has the opposite ends H turned upwardly to form an effective shield for the electrical apparatus. However the plate 10 has an overall length less than the width of the container I9 so as not to interefere with the flow of refrigerated air upwardly around the container l 9. Referring again to Figure 3 of the drawings, it will be noted that the rear end of the plate '10 has a projection 12 which extends through a slot 13 in the inner door panel I5. The front edge of the plate 70 is turned upwardly and forwardly to provide a flange 14 which seats on the flange 59, and is slotted to provide clearance for the thermostat control knob 53.
