(CL 220-4) This invention in its broadest aspect has apner post wires 6 of the end portions 4 and 5 by plication in all fields in which it is advantageous bending the horizontal portions '1 of the side to provide a light, sturdy container which may portions 2 and 3 about the post 6 to form loop be shipped or handled in a flattened form and portions 8.

As shown in Fig. 5 the cover 25 is provided with flanges 28 which are extended and rolled into bearing portions 28'. In order to journal the cover 25 in the bearing 26, an L shaped pin 29 is passed through the bearings 28' and the aligned bearing 26 and secured in place by a key 30. To prevent the pin 29 from rotating relative to the cover, a portion of the pin 29 is passed through an opening 31 in the flan e 28. V
In assembling my i proved knock-down" cabinet, the collapsed frame-work l is first squared. Next, the side and end portions 12 and 15 are suspended in the frame-work 1 by hooking the flanges 13 and 16 over the wires 10 and 11, respectively. The bottom 18 is then lowered between the side and end portions to rest upon the flanges 21. Next, the shell 23' is lowered into the container to' be supported upon the flanges 20 oi the bottom 18. The bottom 18 and the shelf 23 force the side and end portions 12 and 15 out against the retaining wires 9 with the result that these portions are thus rigidly retained in the place and at the same time the necessary transverse rigidity is imparted to the collapsible framework 1. In securing the top 25 to the cabinet, catch members 32, functioning to prevent the top from tilting too far back when the cover is liited, are passed through wire stop loops welded to the wire members 10, the catches 32 being pivotedly secured in the end flanges 28 01' the cover 25 and provided with hook portions 34 which contact with the stop loops 33 when the cover 25 is raised. With the catch member 32 passed through the loops 33, the cover is journaled in the bearings 26 in the manner herebeiore described.
Fromthe foregoing description it will be apparent that I have provided a knock-down cabinet structure which may be readily assembled without special tool or securing means. Furthermore, I have developed an attractive, inexpensive cabinet into which sacked peanuts or the like may be placed and heated, the cabinet being of a type permitting it to be placed in localities from where the heated product may be advantageously vended without special installation.
Having thus shown and described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed but what I claim is:
1. In a knock-down cabinet structure, the combination of an integrally fabricated collapsible wire frame-work, removable sheet metal side and end portions having flanged upper and lower edges, said side and end portions being solely suspended in said frame-work by said upper flanges and a bottom portion supported upon said lower flanges imparting the necessary transverse rigidity to said structure.
2. In a knock-down cabinet structure, the combination of a collapsible wire frame-work, removable sheet metal side and end portions having flanged upper and lower edges, said side and end portions being solely suspended in said framework by said upper flanges anda bottom portion supported upon said lower flanges imparting the necessary transverse rigidity to said structure.
3. In a knock-down cabinet structure, the combination of a collapsible wire frame-work, a removable container forming portion having flanged upper and lower edges, said portion being solely suspended in said frame-work by said upper flange and a bottom portion supported upon said lower flange imparting the necessary transverse rigidity to said structure.
4. In a knock-down cabinet structure, the combination of a collapsible frame-work, a removable container iorming portion having flanged upper and lower edges, said portion being solely suspended in said frame-work by said upper flange and a bottom portion supported upon said lower flange imparting the necessary transverse rigidity to said structure.
5. In a cabinet structure, the combination 0! a frame-work, a removable container forming portion having flanged upper and lower edges, said portion being solely suspended in said framework by said upper flange and a bottom portion supported upon said lower flange.
6. In a knock-down cabinet structure, the combination of a collapsible frame-work, removable sectional container forming portions suspended in unflxed positions relative to each other, and a bottom portion removably suspended upon said sectional portions whereby said sectional portions are flxedly maintained in said frame-work and the necessary transverse rigidity is imparted to said structure.
7. In a knock-down cabinet structure, the combination of a collapsible frame-work, removable sectional container forming portions having flanged upper and lower edges suspended solely from said up r flanged edges freely positioned relative to each other, and a bottom portion removably suspended upon said lower flanged edges whereby said sectional portions are flxedly maintained in said frame-work and the necessary transverse rigidity is imparted to said structure.
