signor to Nash-Kelvinator Corporation, De troit, Mich., a corporation of Maryland Application April 20, 1942, Serial No. 439,617, which is a division of application Serial No. 402,900, July 18, 1941. cation June 22, 1944, Serial No. 541,630

1 Claim. 1

'I'he present invention relates to refrlgerating apparatus, and more particularly to refrigerator cabinet construction.

The present application is a division of abandoned application Serial No. 439,617, filed April 20, 1942, which is in turn a division of application Serial No. 402,900, filed July 18, 1941, and now matured into Patent 2,329,755.

An object of the present invention is to provide relatively thin gauge metallic breaker strips of low heat conductivity for interconnecting the inner and outer walls of a refrigerator cabinet, and .to arrange for securing said breaker strip to said walls in an improved manner.

It is a further object of the present invention to provide for therassembly of the cabinet whereby its internal and external wall surfaces are free of projecting or visible aliixing means, such as screw heads or the like. Y

The invention itself, however, 'both as to its organization and its method of operation, together with additional objects and advantages thereof. will best be understood from the following description of specific embodiments when read in conjunction with the accompanying drawings.

In the drawings: f

Figure 1 is a front view of a refrigerator cabinet with parts broken away; and

Figure 2 is a cross sectional view through a portion of a wall of the cabinet and door.

Shown in the drawing is a refrigerator cabinet y 20 having a food storage compartment4 22. Access opening 25 to the food storage compartment is closed by a pivotally mounted door 26. The compartment 22 is formed by a liner or inner shell |15 having side, top, bottom and rear walls. The edges of the side, top and bottom walls around the opening 25 are marginally anged outwardly at right angles to form a portion of the front wall of the cabinet. as at |14. The marginal edge of the flange |14 is in turn bent at right angles to extend rearwardly parallel to the wall of the liner,

' as at |00.

Extending spatially about the liner |15 is an outer casing or shell |10 comprising top and side walls formed as a unitary structure rolled from a. single sheet of metal. The forward marginal edge of the shell is bent at right angles to extend inwardly peripherally about the door opening 25 to form a. front wall section |13. The front wall |13 is of double wall thickness with the metal doubled back upon itself and continuing along the side wall |10 a determinable distance. and then turned at right angles in spaced parallel extension to the doubled wall |13 as at 1|.

In the form shown the outer shell or casing |10 is formed with a pocket |12 rearwardly of the Divided and this applt double thickness front wall |13. The front wall is set inwardly of the front wall portion |14 of the liner |15. 'I'he Wall |14 is inclined to be in planular alignment with the pocket |13. The wall |14 is ilanged to extend rearwardly parallel to side wall of the liner, as at |80. A breaker strip |16 extends in joining the walls |13 and |14, one end. of which is looped, as at |11, and lies within the pocket |12. The opposite end IBI extends over the face of the front wall |14 to be reversely bent and extending rearwardly, thence upwardly along .the flange to be turned over its end downwardly, as at |82.

The breaker strip |15 is of a flexible relatively thin metallic sheet having a thickness preferably not exceeding.0l0 of an inch, and is preferably formed of stainless steel though it may be formed of other material and suitably coated with enamel or it may plated.

What I claim is:

A cabinet construction comprising an outer casing having a portion forming a, front Wall and having a portion extending in back of said front wall for forming a pocket therebetween, an inner liner disposed within the casing in spaced relation thereto and being provided with an inclined front wall extending outwardly from the liner, said inclined front wall being in alinement with the pocket, and having a, flange extending therefrom parallel to the side wall of the liner, a thin resilient metallic breaker stripextending between said outer casing and liner and having one end thereof reversely bent to provide a. loop, said loop end of said breaker strip extending into said pocket of the casing and resiliently engaging the walls of said pocket. said breaker `strip having the opposite end thereof reversely bent upon itself in a direction toward said outer casing and engaging the inclined wall of said liner, and then bent rearwardly and parallel to said flange of said liner for engagement therewith for securing the breaker strip to said front walls of said casing and liner.
