Application filed August 6, 1910. Serial No. 576,904.

To all whom it may concern.

. Be it known that I, WALTER'H. Wm'rrmn, a citizen of the United States of America, residing at Grand Rapids, in the county of certain new and useful Improvements in Refrigerator-Linings; and I do hereby declare the following-to be a full, clear,'and

exact description of the invention, such as will enable others skilled in the-art to which it appertains to make and use the same.

My invention relates to improvements in" metal linings for refrigerators, and its'obect is to provide a lining that is germ proof, sanitary and easily cleaned, and to provide the same with various new and useful features hereinafter more fully de scribed and claims, reference being had to the accompanying drawings in which:

Figure 1 is a perspective of a refrigerator lining ready to be placed in the refrigerator. Fig. 2' is a plan of a sheet metal blank for forming such lining shown on a reduced scale. Fig. 3 is a vertical section of the device shown in Fig. 1 taken on the line 3-3 of Fig.4. Fig. 4 is a horizontal sec- 'tion showing the bottom in plan view,

- and--Fig. 5 is a perspective detail of one flanges and as at 6 to front flange, and to of'the lower corners of the lining before the corner is finally closed and rounded.

Like numbers refer to like partsin all of gures. I

The vertical walls and the bottom ofv my improved lining are formed or a single piece,

of sheet metal first cut in accordance with the-plan shown'in'Fig. 2 in which the middle portion .l-forinsthe back wall, 2 are side portions to form the sides of a finished linmg. The middle triangulanportion 3 extending jfrom'the back portlon forms the rear portion of the bottom, and the parts 4 extending from the'sideportions 2 form the side portions of the bottom; The .outer edges of the side ortions 2 and bottom portions 4 are, exten form the-depending roperly round the corners ofthe lining where thecorners of the side and back join the corners of the bottom trian lar recesses 5 are out between the midd a bottom part 3 and the side bottom parts to remove surplus material, and the adjacent margins Michigan, have invented of sheet metal by particularly pointedout in the ed as at 8 to form the side e at this point and ietegral vertical walls, an

cesses are also formed which sever and space apart the extensions 6 and 8 at the outer margins of the blank, the inner ends of these recesses being convex in a onefourth circle form as shown at '7. This blank can be made from a rectangular piece cutting recesses in the mar n of the same at one end as shown which istien bent or folded in proper form to form the'back, sides and bottom, and the side and bottom flanges of the finished structure, the vertical and horizontal angles of the same being rounded or concaved in onefourth circle form, and the edges of the parts? and 4 brou ht together as indicated in the drawings. top sheet 9 is also provided having a downwardly turned flange 10 at the front-and'with rounded corners to fit within the top of the described structure. When thus formed the recesses 5 will form 0 enings as at 5 in Fig. 5 whichby a suit a le tool can easily be closed by bending the metal inward around the same and thus forming a smoothly ronndedcorner as at 5.

The seams between the parts 3 and 4, and between the top soldered, welded or brazed isfactory, ti I prefer we readily done to insure a satht and germ proof structure.

by means of a suitable blow pig e or an electric welder.

the corners except at the top are concave on the inner side whereby no sharp angles exist toaflord lodgment for anything what-' ever, thus. furnishing a lining which is very easily kept clean. I

By welding this structure b means of the-blow pipe as suggested, it W1ll stand the heat necessary to coat the same with enamel throughout which I prefer to do thus making a very durable and satisfactory refrigerator lining.

I am aware that sheet metal has been used formaking linings for refrigerators and also that earthenware linings with concave or rounded angles havebeen used. I am however, not aware of any prior method of formingsheet metal linings as-he'rein described, or of any sheet metal lining havi the rounded or concave angles" as shown herein.

What Ifcla laimise-l, j

1. re i rator compri' in Q6 if n-integ i' d l botf 9 and vertical walls can be ding the same, which can be his lining has very few seams, and all Patented Feb. 21, 1911.-

tom, said lining having concave or rounded corners, the bottom being formed of a triangular portion extending from the rear wall together with side pieces extending from the side walls joined to the triangula piece and to each other. V

2. A refrigerator lining, comprising side walls and a rear wall together with vertical front flanges to the side wall, formed up with rounded vertical corners, a bottom integral with said walls and formed of integral members extending inward from the rear wall and side walls and joined at the edges to each other, the side members thereof also having a downwardly extended front flange, and a top member secured to the rear and side walls and also having a depending front flange.

3. A refrigerator lining, comprising two vertical walls, and a bottom integral there-,

with the walls being rounded where joined to each other and to the bottom, and the metal formed inward where the corners of the walls and the corner of the bottom meet to form a rounded or partially globular portion to the lining.

4. A blank for forming a sheet metal refrigerator lining, comprising 'a series of rectangular portions to form the vertical walls, bottom portions extending from the respective endsof the first named portions and adapted to form a continuous bottom when folded inward at right angles to the refrigerator lining, comprising three rectangular portions to form the rear and side walls, a triangular extension on the middle portion to form the rear portion of the bottom, extensions on the side portions to form the side ortions of the bottom, side extensions to orm flanges, said blank also having triangular recesses between the bottom portions to permit forming rounded bottom cor- 11ers and side recesses in the flange extensions having rounded inner ends to form rounded corners in the finished structure.

6. A refrigerator lining, comprising rear and side walls and front vertical flanges, said lining having four rounded or concave vertical corners, a bottom formed of three portions integrally and inwardly projecting from the respective rear and side walls and.

joined to each other by welding, said lining also having rounded bottom corners and a depending front flange,and a top welded at the adjacent edges to the rear and side walls. a

In testimony whereof I aflix my signature in presence of two witnesses.
