My invention has for its object a chaplet i made of a piece of band iron or a sheet metal strip and having two heads or abutting surfaces and webs interconnecting them and located on their outer ends. In contradistinction to known double headed chaplets which either are formed by several parts or are bent in one piece or punchedout of a piece of section iron, my invention consists in the fact that inner supportin ribs are formed still between the heads oft e chaplet to strengthen it, by cut-out or projecting and bent-off lugs, while the, outer webs advantageously are strengthened by bent -of lugs.

The manufacture of chaplets of this t e is cheaper and simpler than that of the c plets hitherto known. The band iron piece the chaplet is made out of may be full or perforated.

In order that my invention can be more easily understood, some preferred embodiments of chaplets having both parallel and inclined abutting surfaces are illustrated by way of example in the accompanying drawing in which Figures 1 to 3 show an embodiment in which the inner supporting stays are cut out of the one, full abutting wall and bent-off, and more particularly Figure 1 is a top view of a sheet metal strip serving to form 'a chaplet and having bent-oif strengthening lugs for the outer webs and cutout portions adapted to form inner'supporting stays when bent.

Figure 2 is a lateral view' of the finished chaplet, f

Figure 3 is the top view corresponding to Figure 2,

Figures 4 to 6 are views corresponding to those of Figures 1 to 3, of another embodiment in which the one inner supporting stay is cut out of the one, full supporting wall whilst the other is cut out of the other abutting wall that includes the joint,

Figures 7, 8 and 9 are similar views of an embodiment of my improved chaplet in which the abutting surfaces are inclined to each other, the inner supporting stays being formed by lugs that in the blank shown in Figure 7 project on the ends thereof and are 400,899, and in Germany August 28, 1929.

bent-olf to form the inner stays, as illustrated in Figure 9. v

-In all the embodiments shown 1 denotes a full-face or perforated sheet metal strip or piece of band iron, from which is manufactured the chaplet by twice bending the ends toward one another. The places where the blank is bent are marked by dotted lines 2. Owing to this bending operation the finished chaplet has the form of a frame the one abutting wall 3 of which is undivided while the opposite wall 4 is formed by the butt jointed end ortions of the blank. The lateral webs are enoted by 5. These webs are lstrengt ened advantageously by lugs 6 obtaine b providing a U-shaped cut between the ben lng lines 2 of each end of the blank and bending oi the respective `cutout portions at right orl obtuse angle relatively to the surface of the blank. The inner supporting stays are denoted by 7 and their bending lines by 8. The arrows indicate the bending directions.

The joint of the finished chaplet which in the embodiments shown is situated in the midst of one of the abutting walls, may be provided on another suitable place of the chaplet.

What I claim and desire to secure by Letters Patent is 1. As anew article of manufacture a chaplet consisting of a metal strip bent to a frame having two op osite walls and two webs interconnecting t e opposite ends thereof, and supporting stays arranged between said opposite walls and formed by cut-out and bentoif portions of the latter. f

2. As a new article of manufacture a chaplet consisting of a metal strip bent to a frame having two opposite walls and two webs interconnecting the opposite ends thereof, supporting stays arranged between said opposite walls and formed by cut-out and bent-off ortions of the latter, and ribs adapte to strengthen said webs and formed by cut-out .and bent-oif portions of the latter.

In testimony whereof I aiiix m signature.
