' Application filed larch 7, 1828. Serial No. 259,859.

This invention is a novel improvement in cabinets and the like having one or more shelves of sheet metal, and the principal objects of the invention are to provide a sheet 5 metal shelf, made in one or two parts, which may be readily cut and shaped to fit within the walls of any rectangular or other shap'ed cabinet of sheet metalor wood, the rear and side edges of the two members of the shelf being rolled away from the plane of the shelf so as to form a rounded tangential connection between the shelf and walls of the cabi- *net, thereby roviding a more sanitary con- .nection by ispensing with the usual hard corners in which dirt and bacteria lodge and remain even when the shelf is washed. The rounded corners and edges furthermore impart a neat and attractive appearance to the shelf when assembled in the cabinet.

A @rther object is to provide a two part shelf s above described in which the two sheet metals, members of the shelf, after be- "ing fabricated are spot-welded together to form a unit, and then the rounded edges of 2 the uppermembers are spot-welded to the walls of the sheetimetal cabinet to permanently secure the shelf in place, there y ais pensing with the usual projecting heads of fastening bolts or screws, and resulting in 30, the provision of smooth faces in the shelf. I v I will explain the invention with reference to the accompanying drawing which illustrates one practical embodiment thereof to enable others to adopt and use the same; and

will summarize. in the claims the novel features of construction, and novel combinations of parts, for which protection is desired,

In said drawings Fig. 1 is a perspective view of a ortion of a cabinet havlng an open front, an show-.'

ing one of my novel shelves secured therein. Fig. 2 is a transverse section on the line Q Fig. 3- is a top and bottom-plan View of one of the top and bottom inner corners of the shelf, showing in dotted lines the V-shaped cut in the.corner and the rolled ed es flattenedout.

so ig. 4 is an enlarged pers ective view of the near corner of the shelf 5 own in Fig. 4, thewalls of the cabinet being removed;

upper and lower The cabinet preferably comprises a sheet metal rear wall 1, opposite side walls 2 and 3 respectively, and stri s 4 at the front of the cabinet, all of whic may be formed integral, or separately and united by any suit-v able means. Preferably the front of the cabinet is open, except for the strips 4, to one of which a door (not shown) may be hingedly or otherwise secured.

The shelf 5 is made of sheet metal and has a substantially'V-shaped cut in each of its rear corners as at 5, (Fig. 3) and the edges are rolled upwardly as at 5", the sides of the out 5 meet on the line 5 (Fig. 3),the rolled edges of sheet 5 fitting squarely within the interior of the cabinet. In case the front of the cabinet were also closed the .two front corners of the shelf 5 would be likewise cut and the front edge of the shelf would be likewise rolled upwardly.

Where however as in: Fig. 1 the front of the cabinet is open, the front edge of shelf 5 is flanged downwardl as at 5 between the strips 4, the lower e ge of the flange 5 'being bent back upon itself as at 5 for neatness and additional strength. a

On the under side of sheet 5 is a similar sheet 5 similar in size and shape with member 5 except that the front flange 5 is omitted. Member 5 may if desired be made of somewhat lighter stock than member 5. The cpsners and edges of-membe'r 5 are formed and .shaped identically the same as those of member 5 as shown in Fig. 3, except that the rounded edges 5" thereof are rolled downwardly instead of upwardly, as shown in Figs. 1, 2, and 4. The two plates 5 and 5' when fabricated and assembled are preferably spot-welded together as atj5, but may be otherwise insepa'rably secured together to form unitary structure, and. after the shelf unit is adjusted in position within the cabinet the rolled edges of the upper member 5' are preferably spotwelded as at 5 to the walls 1 and 2 of .the cabinet. Other means of securing theshelf totheycabinet-walls however may be used, and if the cabinet is made of wood the screws and/or bolts may be usedf The opposed rolled edges of the shelf members 5 and 5, and the welded connections 5 and 5 impart a great rigidity to the cabinet shelves and their cabinet walls.

I do not limit my invention to the exact form shown in the drawing for obviously changes may be made therein within the scope of the claims.

I claim I 1. A shelf having a substantially flat bottom and flanges extending both upwardly and downwardly on at least three sides thereof, the said flanges being curvilinear in crosssection and merging into the said bottom.

2. In a shelf as set forth in claim 1, the ad-! jacent ends of the said flanges abutting.

3. A shelf comprising an upper member having at least three of its edges rolled upwardlyon an arc of approximately 90 degrees, and a similar lower member united to the upper member and having the corre sponding edges rolled downwardly on an.

arc of approximately 90 degrees.

4. In a shelf as set forth in claim 3, the adjacent ends of the said edges abutting.

5. In a cabinet; a sheet metal shelf comprising an upper member having its edges rolled upwardly tangent to the cabinet walls; and a similar lower member having its edges rolled downwardly tangent to the cabinet walls; the members of the shelf being united together, and -the rolled edges of the upper member of the shelf being united to the cabinet walls.

6. In a sheet metal cabinet; a sheet metal shelf comprising an upper member having its edges rolled upwardly tangent to the cabinet walls; and a similar lower member having its edges rolled downwardly tangent to the cabinet walls; the corners of the members of the shelf being cut away, the opposite sides of the cut abutting when the edges are rolled;

the members of the shelf being united together, and the rolled edges of the upper member being united to the cabinet Wall's.
