advantages thereof will fully appear upon consideration of the following descriptionin conjunction with the accompanying drawings forming part of this specification, and of which:
Fig. 1 is a perspective view of a refrigerator cabinet embodying the invention;
Fig. 2 is a vertical section of the refrigerator;
Fig. 3 is a horizontal section taken on line 3-3 in Fig. 2; and
Fig. 4 is a rear view of the refrigerator. Referring to Fig. 1, a refrigerator cabinet l0 provides a thermally insulated storage compartment accessible by means of a door l2. The
cabinet includes a front frame l3 constructed |3 by screws 20. The liner i8, which forms the storage compartment i|,-may be coated on the inside with porcelain enamel, as well known, and is provided in the rear with an opening, which may be referred to as a liner opening, surrounded by a wood frame 2| through which the cooling element 22 of a refrigerating apparatus may be inserted. To the liner opening frame 2| and the front frame |3 are secured a plurality of' insulating members 23 consisting of corrugated cardboard sheets faced with metalfoil, in spaced relation to each other and parallel to the liner it. The sheets 23 are provided with flanges '31 and may be secured to the liner opening frame 2| and the front frame l3 by nails or other fastening means. It will be understoodthat the frames may be constructed of other material than wood, and other types of insulation may be employed.
The rear portion of the cabinet consists of upright corner posts 24 and 25 joined by a cross member 26, of steel or wood, at approximately the level of the front cross member To the inside 'of the rear corner posts 24 and 25 are secured, for example, by screws 21, the side edges 23 and 29 ermany October 5, 1934 of a generally U-shaped metal plate, extending from the top of the posts 24 and 25 to approximately the level of the front cross member H. The plate 3|) forms the supportingstructure for a refrigerating apparatus 3| the cooling element 22 of which is adapted to be disposed within the storage compartment The front section of the cabinet including the frame l3, the liner I8 and insulation members 23, and the rear section including the corner posts 24, 25, the plate 30 and the refrigerating apparatus 3|, are telescoped together by inserting the cooling element 22 through the liner opening frame -2| into the storage compartment forming a double cantilever arrangement whereby both sections are mutually supporting. The plate 30 is provided with a block of insulation material 32 which is disposed within the liner opening frame 2|. The liner. opening is sealed on the inside by a liner opening trim member 33. p
The outer wall or casing 34 of the cabinet consists of an inverted U-shaped sheet of metal, which isgiven any desired finish, and which is placed over the rounded frame l3 and rear cor-" ner posts 24 and 25 and extends downwardly on each side to the cross member I]. The casing 34 is secured by nails or screws to the wooden frame and corner posts. The top rear portion of the casing or cover 34 is cut out and provided with a downward flange 35 which is secured to the.
