The disclosure in this application is related to the disclosure in an application of Louis Ruthenburg, Serial No. 7,667, and an application of W. D. Collins, SerialNo. 7,733.

Referring to the drawings, we have shown in Fig. 1 a refrigerator cabinet [0 having a ther- In Figs. 2 to 6 inclusive is shown a frame which forms what may be referred to as the backbone of the cabinet. 'The frame is fabricated of iron or steel members which are welded together to form, in a general way, a chair-like structure. The bottom of the frame is formed by four generally channel-shaped members welded together at their ends. In Fig. 2 may be seen the outline of the front cross member l3 and the rear cross member I4. The front and rear members [3 and M are connected by side members l5-and l6 (Figs. 2 and 3). At the front corners of the bottom of the frame are 1935, Serial No. 13,603

two upright members I! and I8. These members are substantially Z-shaped. The joint in the lower left hand corner of Fig. 3 is shown enlarged in Fig. 5. At the rear corners of the. bottom of the frame are connected upright members l9 and 20 which are also channel-shaped as may be seen in the top view in Fig. 4. Near the top of the rear upright members l9 and 20 are secured forwardly projecting arm members 2| and 22. The upper ends of the rear uprights l9 and 20 are connected by an angle iron crossbar 23. Between the rear frame uprights l9 and 20, at the level of the upper ends of the front frame uprights l1 and I8, is connected a crossbar 24 having a semi-circular offset 25. Between the upper ends of the front frame uprights l1 and land the cross-bar 24 is mounted a horizontal sheet 26 havinga semi-circular portion 21 cut out at the rear edge to correspond with the semi-circular offset 25 in the cross-bar 24. The front of the sheet 26 is formed as a. step 28. Thesheet 26 is formed with a downturned flange 29 along the front edge and downturned flanges 30 along the side edges. In Fig. 6 is shown an enlarged view of the joint between the sheet 26 and the front frame upright l8. At each corner of the bottom of the frame are secured plates 3|. These plates may be referred to as base mounting plates and are for the purpose of securing the legs of the base 32 of the refrigerator, shown in Fig. 1.

Referring now to Figs. '7 and 8, we have shown a refrigerator storage compartment which may be separately formed as a unit, for instance, as generally disclosed in Patent No. 1,878,111 to W. D. Collins. The compartment is formed by a. substantially rectangular casing 33, generally referred to as a liner. The liner 33 is preferably heavily porcelained on the interior, as well known, to provide sanitary walls for the storage compartment. The edge of the liner 33 is secured within a substantially rectangular wooden frame 3t. form of substantially rectangular slabs is secured around the outside of the liner 33, for instance, by thin straps or bands 36. It will be understood that any suitable means may be employed for secur ng the insulation in place around the liner. In the sectional view of the storage compartment assembly as shown in Fig. 8, there may be seen what is referred to as a window. This is an opening 31 through the rear wall of the liner 33 and insulation 35 to permit insertion of a cooling element into the storage compartment when a refrigeration apparatus is assem- Thermal insulation material in the bled with the cabinet. Below the window 31, the insulation is indented to form a semi-circular groove 38 which receives a portion of a refrigeration apparatus, namely, a gas heat exchanger of a refrigeration apparatus of the pressure equalized type.

The next step in the process of fabricating the cabinet is to mount the storage compartment assembly, just described, in position on the previously described frame. The position of the storage compartment assembly on the frame is indicated in dotted outline in Fig. 2. The lower edge of the storage compartment frame is formed with a step 39 (Fig. 7) which fits the step 28 of the steel frame. This permits accurate location of the storage compartment assembly on the frame. The semi-circular offset 25 in the crossbar 24 and the semi-circular opening 21 in the rear edge of the sheet 26 are aligned with the semicircular groove 38 in the insulation material at the back of the storage compartment assembly. The forward ends of the arms 2| and 22 at the top of the steel frame are secured to the top of the wooden frame 34 of the storage "compartment.

In Fig. 10 is shown what is referred to as the front panel 5| for the refrigerator cabinet which panel is substantially in the form of an inverted U. The front panel 5| is turned rearwardly around its periphery and is formed with a step so that, after the panel has been coated with a desired material, as, for instance, porcelain, it has the appearance indicated in Fig. 1. The periphery of the front panel 5| is turned inwardly to form a flange 40. The flange 40 is provided with tabs 4| along each side of the panel.. The front panel 5| is placed against the front of the pre- I viously described frame and storage compartment assembly and secured in place by fastening the tabs 4| to the wooden frame 34 around the storage compartment door opening and the front frame uprights l1 and 8.

In Figs. 11 and 12 are shown side panels 42 for the refrigerator. 'The side panels 42 are coated similarly to the front panel 5| as, for instance, with porcelain. The bottom and rear edges of the side panels 42 are flanged inwardly and the forward and top edges of the side panels are provided with L-shaped flanges 43 and 44 respectively. The L-shaped flanges 43 on the forward edges of the side panels 42 are provided with a plurality of notches 45 which are spaced apart the same distances as the tabs 4| on the front panel 5|. The side panels42 are placed in position on the sides of the refrigerator cabinet, as thus far assembled, by inserting. the L-shaped flanges 43 on the forward edges beneath the-flange 40 of the front panel 5|, the tabs 4| on the front panel 5| extending into the notches 45 and beneath the L-shaped flanges 43 on the forward edges of the side panels 42. The inturned flanges at the rear of the panels 42 are secured to the tially chair-shaped metal frame having a rectangular .base formed by four channel members rear frame uprights l9 and 20. The forward edges of the side panels 42 arethus locked beneath the edge of the front panel 5| and require no other- At the same time, the side' The top is substantially flat with downwardly rolled sides. The side edges of the top panel 46 are flanged inwardly and the forward edge is provided with an L-shaped flange 41 similar to the flange 43 on the side panels 42 except that the flange 41 is continuous, there being no tabs along the top edge of the front panel 5|. The top panel 46 is placed in position on the top of the refrigerator by inserting the L-shaped flange 41 beneath the flange 40 along the top edge of the front panel 5|, and lowering the sides onto the top edges of the side panels 42 to lock the L-shaped flanges 44 on the side panels.

The rear edge of the top panel 46 overlies the space between the two rear*- frame uprights and 20 and is provided with a recess 48. This recess permits air to flow upwardly through the space between the frame uprights I9 and 20 and out at the top of the'refrigerator. A ledge 49 around the recess 48 is provided to support a suitable screen or grille, not shown. In order to prevent air from circulating rapidly beneath the top panel 46, a sheet metal plate 50, referred to as an air deflector, is'mounted above the top cross-bar 23 at the top of the rear frame uprights l9 and 20 (Fig. 2).
