METAL SHELVING AND METHOD OF MAK INGTHE SAME 7 Robert T. Stophlet, Toledo, Ohio, assignor to The Toledo Porcelain Enamel: Products Company, Toledo‘, Ohio, a corporation of Ohio Application March 26, 1935,‘ Serial No. 713,094 5 Claims. (Cl. 113-116) This invention relates to metal shelving and its principal object is the provision of a light, rigid shelf that is attractive in appearance, economical to manufacture and which will withstand high temperatures so that it can be vitreous porcelain enameled without becoming distorted. Other objects and advantages will be apparent from the following description, in which reference is had to- the accompanying drawings illustrating 10 a preferred embodiment of my invention and wherein similar reference numerals designate similar parts throughout the several views. In the drawings:-Figure I is a view in perspective of a shelf con- 15 structed in accordance with my invention. Figure II is an enlarged plan view of a ?at blank fro-m which the shelf shown in Figure I is formed, the central part of the blank being broken away. 20 Figure III is a view in perspective showing the blank after the ?rst forming operation; and Figure IV is an enlarged end elevational view of the shelf illustrated in Figure I. ' ' loads without sagging, the stiffening means consisting of a bead or groove 2 extending longitudinally of the shelf intermediate its sides, mar- 30 ginal beads 3 and 4 extending along the sides of the shelf and ?anges 5 and 6 depending from the marginal beads 3 and 4. Since either the ?ange 5 or the ?ange 6 may form the front of the shelf, the edges of the ?anges are turned under, as at 1 35 and 8, to enhance the appearance, and the ?anges are perforated, as at 9, In and II, to facilitate , , and 4 may be formed and the side and end ?anges bent down by means of forming dies in the 15 same operation, the edges of the side ?anges being subsequently turned under as at 1 and 8. The stiffening bead 2 will project downwardly, as illustrated in the drawings, or upwardly, depend ing upon the direction in which the side and end 20 ?anges are bent, but the shelf is preferably so formed that'the stiffening bead 2 Will project upon the shelf. It is possible to bend downward ly the end ?anges l6 and I‘! of blanks- not pro- 25 vided with openings Such as '3 and '9, but be cause of strains set up in the metal of'blanksznot provided With Such openings, Warpage is liable to occur when the blanks are subjected to the tem peratures required to fuse coatings of vitreous 30 porcelain enamel 1119011 them~ The embodiment of my invention herein ‘shown and described is to be regarded as illustrative only, and it is to beunderstood that the inven tion is susceptible to variation, modi?cation and 35 change within the spirit and scope of the sub joined claims. , Additional stiffness may be attained when desired by providing two or more beads instead of 40 the single head 2. with the openings 18 and iii. If desired, the blank may be cut to shape and the perforations andiopenings punched by means of blanking dies Oi in one operation. The stiffening bead 2 is prefer ably stamped or rolled into the blank after it is out and punched, the blank thus assuming the form illustrated in Figure III. The marginal beads 3 and 4 may be formed and the side ?anges 10 5 and 6 and end ?anges l6 and I1 bent down in separate operations, but where the quantities to be manufactured are large, the marginal beads 3 downwardly so as not to engagearticles placed Referring to» the drawings in' detail, the shelf l 25 of my invention, though light in weight, is stiffened so that it is capable of supporting heavy fastening of price tags thereto». out into the shape illustrated in Figure II and provided with perforations such as 9, ll, etc., and , _ Having described my invention, Iclaim:1.
