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.

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

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

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
