7 Application and December 5, 1921. Serial No. 5204961 To all whom it may concern:

' Be it known that I, SHERIDAN A. WALKER, a citizen of the United States, residing at the borough of the Bronx, city of New York,

a v5 county of the Bronx, and State of New York,

have invented a certain new and useful Improvement 1n Refri erators, of which the following is a speci catlon, reference being bad to-the. accompanying drawings, which tions with reference to each other and separating them from each other. Between said 1 'form a part of the same.

An object of my present invention is to construct a metal refrigerator in such man+ ner as to insure protection for the contents of thesame from the outside elements and have thefsame adaptable at all times ior convenient cleaning. v 1 Another object of my invention is to make my refrigerator in such manner as will conveniently permit of quantity production.

Other objects and advantages of my .in- 'vention will be readily seen from reading this specification, taken in connection withthe accompanying drawings, in which Fig. 1 is a perspectiveyiew of the side walls, stiles and railsof my refrigerator,

together with a-similar view of the inside walls thereof Y Fig. 2 is across section of my refrigerator looking from one end thereof;

Fig. 3 is a cross section of the same look- 80 ing from the front f F 1g. 4 IS a cross section looking from the.

top of the'refrigerator; and

a ig. 5 is a detail of. construction thereof. Referring now in detail to the drawi 's,

6 represents theouter walls of the refrigerator which are made of one piece of metal and are provided with rounded corners 7" and offset marginal ends'8forming flanges. The stiles 9 are gnade of substantially U 'form, having's'teps 10 at their'adjacent surfaces. I" have provided-rails .11, 12 and 13 adapted to. connect the stiles 9 to,;eachother,

the ends of these rails being mitered to correspond with the steps 10 of the stiles 9. At the ends (if these rails I have provided flanges 14. which form spot .weldin surfaces permitting of the electrie'weldmg of the rails in position between their stiles.

.also provided with rounded corners 16 and marginalflangesfl. This inner wall sec-'- tion is adapted tobe inserted'inside the outer wall section 6 and the flanges 17 fit over the inner wall portions 18 of the stiles 9in such manneras to make a. flush io'int Theinner walls of therefrigerator 15 are between the stile portion 18 and the inner wall 15, on the chamber sideof the said we 1 portion. The flange l7 and stile portion 1 may be welded in the positions shown.

At convenient places between the inner wall portion 15 and outer wall portion 6 I. I have provided braces 19 to which are welded the said wallportions and which perform the double oflice of supporting the wall por wall'portions15 and 6 is an air chamber 20, which, however, may be filled with suitable heatresisting material as for instance mineral wool. T

I'The bottom of the outer wall sectionfi is provided witha floor 21 which is flanged along its marginal ends 22' so as to provide a welding surface to connect the same with the outer wall section and'the lower rail 11. as shown. The upper end of the outer wall section" is provided with a cover 23 having an ofi'set .flange24 along its marginal'edge to provide a connecting surface'to-the outer .wall section 6. I preferably connect said when required, as by friction. The'uppecil' part of the inner wall section is provi with an enclosure 25 having a marginal flange 26 to provide a welding surface to connect the same to the upper'en'd of said inner wall. At the 'lower end of said inner wall I have provided a. closure 27 having the welding marginal flange 28 adapted to con nect the same to the 'bottom ofsaid inner wall. The'closure 27 is preferably provided withrounded corners as shown. Legs 29 are provided to support the refrigerator clear of the floor. "I have provided

doors

30 and 31 which may be hinged in any convenient mam '1101' to my structure and which may be fastoned in any convenient 'manner in the re ister with the steps of therails andsti-les.

l have purposely omitted to show any racks or shelving in my refrigerator as these do not form anypart of my present invention. Racks and shelving, however, of

any desired form may be used in conjunction with: my refrigerator and it is obvious that for saidpurpose, brackets may be placed in convenient 15 to support t e same.

[10 ositions on theinside walls It will be observed that both stiles used in my refrigerator are of the same design and may be rolled or stamped with the same die. The

rails

11 and 13 have the same stepped arrangement as the rail 12 and may be formed by the same die as that forming rail 12 and in the same manner When thus formed, the rail may be out along its central portion for the purpose of forming the

rails

11 and 13. On the rail 12 I have provided Welding flanges 33 adapting the said rail to have welded thereto the closure plate 34.

In order to assemble my refrigerator I prefer to -weld the stiles 9 and

rails

11, 12 and 13 .into one unit. The inside wall section is then connected through its flanges 17 with thc lmarginal ends 18 of the stiles 9 and welded in position. The top closure 25 is then fitted into this inner section and welded through its welding flange 26 to the said section, and the closure 27 is fitted onto the bottom of the said inner wall section and welded thereto through the welding flange 28 of said closure. The supports 19 arethen put in place where desired and the outer wall section 6 is then fitted through its welding flanges 8 onto the outermarginal edges of the stiles 9. The flanges are so arranged to form a flushed joint on the outside of the refrigerator. The outer wall (5 may then be welded to the braces 19. The bottom closure 22 is then put in place and welded through. its marginal flange 21 to the outer wall section and the lower rail ll of the refrigerator. The legs 29 are then put in place and connected in any convenient manner. The cover 23 may then be frictionally attached or otherwise secured to the outer wall section 6 and the top rail 13. The doors may now be put in place in any convenient manner as by hinging the same outer and inner wall sections, said stiles having side plates adapted to be connected to said outer and inner wall sections and the upper rail between said stiles having an upward flange therefrom, and the top closure of the outer wall section being adaptedto 'frictionally connect with said outer wall section and said upper rail.

2. In a refrigerator, inner and outer wall sections, stiles, and rails, said stiles having side plates adapted tobe united to said outer and inner wall sections, spaced closures for the top and bottom of said outer and inner wall sections respectively, the upper rail being provided with an upwardly disposed flange, and the top closure of the outer wall section being adapted to frictionally connect with said outer wall section and said upper rail.

In a refrigerator, inner and outer wall sections, stiles, and rails, the said stiles having side'plates adapted to be united to said inner and outer wall sections and form a part thereof, said inner and outer wall sections having spaced tops and bottoms, a downwardly depending flange on the top closure of the outer wall section, the upper rail being adapted to frictionally connect with the said top closure.

' 4. In a refrigerator, inner and outer walls in spacedrelationship to each other, stiles and rails, said rails being connected at both ends to said stiles and said stiles having side plates adapted .to be united to said inner and outer wall sections, and form a part thereof, said inner and outer wall sections having spaced tops, a downwardly depending flange on the top closure of the outer wall section and the upper rail, and spaced said construction being such as to maintain a speced relationship between the inner compartment and the outer compartment of 100 said refrigerator.
