` State of Massachusetts, have invented certain -ferent shapes of the saine.

new and useful Improvements in Ornamental Chain-Links, of which the following is a specication.

This invention relates to an vornamental chain-link of that class known as ,s`tretcherlinks, or such links which can be extended to a certain extent, so as to prevent the breaking of the chain or the tearing of the garment to which the end of the chain may be attached; and the invention consists of an ornamental chain-link formed of a spiral spring, two slidelinks engaging the spiral spring at opposite ends, and an inclosing sleeve or boxprovided with pockets for guiding the links, all as will be more fully described hereinafter, and nally pointed out in the claims.

In the accompanying drawings, Figures 1, 2, 3, and 4 represent side views of my improved ornamental chainlink, showing dif- Figs. 5, 6, 7, and S are vertical transverse sections of Figs. 1, 2, 3, and 4, respectively. Figs. 9 and 10 are detail side views, respectively, of the spring and- Similar letters of reference indicate corre-l sponding parts.

Referring to the drawings, A represents a spiral spring, and B B two links which are made to slide either Asidewise of each other at their adjoining faces or which are guided by the inclosing box or sleeve C at any suitable angles to each other. The spiral spring A is placed in the links B B, and retained by the opposite ends of the same, as shown in'dotted lines in Figs. 1 and 4. The spiral spring A and links B B are inclosed by the sleeve or box C, which is made of any suitable crosssection, as shown in Figs. 5 to 8, and which serves to establish the connection of the links and spiral spring A without any other fastening devices. The opposite ends of the links,

which project beyond the sleeve or box C, are provided with rings a a, which prevent the sleeve or box from getting detached, and by 5o which the chain-link is connected with th adjoining links.

The inclosing sleeve or box C may be made l plain or ornamental, of one or more sections, and of different forms or shapes, and provided 5 5 with guides or pockets b for the linksas shown in Figs. 7 and l1, the ends of the oval shown in Fig. 5 and the corners of the triangle or square shown in Figs. 6 and 8 acting as such guides or pockets when. the sleeve is made of 5o such cross-section. Vihen the sleeve is angular in cross-section, three links, B, may be employed, as shown in Fig. 6. The sleeve forms, with the interior spiral spring and sliding links, an extensible or so-'called stretcher- 6 5A link77 that gives to a certain extent when strains are exerted thereon, so as to prevent the breaking of the chain or tearing of the garment to which the chain is applied.

' Having thus described my invention, I claim 7o as new and desire to secure by Letters Patent- 1. rIhecombination of a spiral spring, links engaging said spring by their opposite ends, a box or sleeve inclosing said spring and links and having pockets for guiding the latter, and 75 rings applied to the outer ends of the links, substantially as set forth. l

2. The combination of a spiral spring, links sliding sidewise of each other and engaging said spring by their opposite ends, a box or 8o i In testimony that I claim the foregoing as 8 my invention I have signed my name in presence of two subscribing witnesses.
