June 5, 1934. a. sQHQFER CHAIN MAIL BAND FOR ARTICLES OF JEWELRY Filed NOV. 27, 1951 Patented June 5, 1934 UNITED STATES CHAIN MAIL BAND FOR ARTICLES OF JEWELRY Eugen Schofer, Pforzheim, Germany Application November 2 7, 1931, Serial No. 577,722

In Germany February 2, 1931 1 Claim.

This invention relates to a chain mail band for articles of jewelry, the links of which consist of a narrow back strip corresponding in length to the width of the band and having claws, bent twice at right angles, arranged mutually displaced on the longitudinal sides of the back strip. These claws embrace the back strip of the next following link, between correspondingly displaced claws on this link.

The known chain mail bands of this type possess the disadvantage, that they are open on their side edges and that the links can unhook when the band is being bent, as they are not connected sufficiently tightly on the edges.

In order to overcome this objection it has been proposed to arrange on the ends of the back strip claws of half the width of the back strip on one side of the back strip on the ends of the same, said claws being bent twice at right angles and engaging over the free halves of the end edges of the back strip of the next following link. In this manner the edges of the chain mail band are covered and reinforced, the mutually displaced edge claws forming at the same time a Meander-like decoration.

In order to prevent the claws from bending open and loosening the union of the links, especially the half width edge claws, the ends of the two edge claws and of the two extreme claws have accordingto the invention, hooks, which, after the links have beenfitted and bent together, bear against the roots of the edge claws of the next following link.

In this manner the links, especially on the highly stressed edge, are so united that their clawscannot bend open, even under the strongest tension.

An embodiment of the invention is illustrated by way of example in the accompanying drawing, in which:-

Fig. 1 shows a length of chain mail band in perspective view.

Figs. 2, 3 and 4 show in perspective views a link of the chain mail band in the different stages of production. 1

Fig. 5 is an edge view of the band.

Fig. 6 shows the chain mail band in cross section.

Fig. '7 is a perspective view on a larger scale, showing the hook connection on the edge of the links.

The chain mail band 19 (Fig. 1) looks as if it was composed of several longitudinal rows of small, rectangular, interconnected links. In reality however the band links 20 (Fig. 4) extend over the entire width of the band and consist each of a back strip 21 serving as hinge axle, on the two longitudinal sides of which mutually displaced claws 22, each bent twice at right angles, are arranged which grip over the longitudinal edges in the gaps 24 between correspondingly displaced claws 22 of the next following back strip 21. Claws 23, half the width of the back strip 21 and also bent twice at right angles, are arranged on the end edges of the back strips 21 and embrace the free halves 25 of the end edge of the next following link 20 provided with correspondingly displaced end claws 23.

Such a link 20 is formed from a stamped blank 26 (Fig. 2), which consists of the back strip 21, the wide claws 22 arranged the one opposite the other and mutually displaced on the longitudinal sides of the back strip 21 and of the half width claws 23 arranged on one side on the end edges of the back strip, the ends of the

claws

22 and 23 being bent upwards at right angles (Fig. 3) and then again bent upwards at their points of transition. After a fresh blank according to Fig. 3 has been inserted, the claws are bent around the back strip 21 of the next following link.

The two half width edge claws 23 and the two outer wide claws 22 are provided with hooks b and a respectively. The hooks a of the wide outer claws 22 are, after being bent twice at right angles, directedoutwardly and bear from below and from above respectively against the bases-of the end claws 23 of the next following link (Figs. 5 to 7) The hooks b of the half width edge claws 23 are, after the bending, directed downwards in the case of the upper claws 23 and upwards in the case of the lower claws 23 and bear from the inner side against the bases of the edge claws 23 of the next following link (Figs. 5 to 7) The

claws

22 and 23 are secured by the hooks a and 22.. against bending upwards in the case ofv the band 19 being subjected to tensional stress, and consequently the holding together of the links is ensured.

I claim:--

A chain mail band for articles of jewelry composed of links, each comprising a narrow back strip corresponding in length to the width of the band, several claws bent twice at right angles arranged mutually displaced along the longitudinal sides of said back strip adapted to engage the free edges in the gaps between the claws of the next following link, two claws half the width of said back strip also having two right angular bends arranged one at each end on one side of the end edge of said back strip each adapted to engage over the free half of the end edge of the back strip of the next following link, and a hook on the end of each half width claw and on each of the outermost of said claws on the lonigtudinal sides of said back strips adapted after the fitting and bending together of the links to bear against the base of the next following link.
