. To all whom it may concern:

- at intervals along their length and forming,

- 1 invention consists ofcertain novel features Be it known that I, CARL ScHaAYssnunrt, a citizen of the United States,'re's1d1ng at Providence, in the county of Providence and State ofR-hode Island,f'have invented certain new. and useful Improvements in Chains, of which the following is a specifi. cation. J

This invention relates to an improved construction of link for ornamental chains for personal wear; and has for its object to provide simple and effective construction of such a link .by interlocking together twp loop links, one within the other.

. A further object of the invention is to set two elongatedloop linksone within the other, the side arms of each being depressed corresponding inward projections along theirinner surfaces, the projectionsv of one link extendinginto the spaces between the projections of the other link to present the appearance of a plurality of separate links connected together.

' With these and other objectsin view, the

of construction, as will be more fully de scribed, and particularly pointed out in the appended claims.

In the accompanyin drawings:

Figure 1 is a view i ustrating a plurality of my com ound links flexibly connected by connector llIlkS.

perspective view of one of the compound link as cut forcing the inward projections of the outer,

link into the space in the inner link.

Figure 6 is a central sectional view on line 66 of Figure 5, showing the projections of the outer link as extending through the spaces in the inner link.

Figure 7 is a sectional elevation taken at CHAIN.

right angles to thatof Figure 6, showing the spaces in the inner link through which the projections of the outer link extend.

It is found in the practical. construction of fancy shaped, ornamental chain links for personal wear, of advantage to blank the links lnto elongated loopform and to interlock two of these elongated links together by formmg spaces at intervals along themner llIlk', by forcing portions of the side arms together and forming similar spaces and projections on the outer link, the projections of the outer link extending into the spaces of the inner link to lock the two together and to present the'appearance of the socalled Boston link; and the following is a detailed description of the resent embodiment of my invention and s owin one construction of link by which these advantageous results may be accomplished.

With reference to the drawings, 10 designates the outer link member of the compound link, whichnis preferably cut from sheet stock forming a one-piece elongated loop-shaped link. The opposite arms of this link are then pressed inwardly at intervals along their length as at 12, causing the stock on the inner surface to extend toward each other as at 13, but these projections are primarily left spaced sufficiently to receive the inner link member 14 between them.

This inner link member 21 is constructed similarly to the outer link member in that its side arms 15 are pressed, swaged or bent inwardly as at 16 at intervals along its length forming inwardly-extending projections ,17 on its inner surface thereby providing aplurality of spaces or loops between the inwardly projecting portions. The inner link thus formed is then passed into or between the prepared arms of' the outer link to set at right angles thereto then the arms 11'of the outer link are forced inwardly causing the inward projections '13 thereof to extend through the spaces 18 in the inner link interlocking the two links together in such position as to present the appearance of the linking together of a plurality of square links to give the appearance of the so-called Boston link, the length of the inner link being less than that of the outer link for the reception of the connecting links 20 by which these compound links are flex- My improved chain link is very simple and practical in construction, is very ornamental in appearance, and is strong and durable and by its construction the much desired appearance of the Boston type of link is obtained by a very inexpensive method of construction.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by, the terms of the appended claims.

I claim:

1. In a chain, two elongated loop links set one within the other, each having depressions in its side arms forming corresponding projections on their inner surfaces extending toward each other, the inward projections of one extending into the spaces in the other interlocking the two together to present the appearance of a plurality of separate links.

2. In a chain, an elongated loop link having its side arms bent inwardly toward each other at intervals and another similar elonward each other and abutting in the spaced openings in the first link to present the appearance of a plurality of separate interlocking links.

3. A chain link formed of two elongated loop links set one within and at right angles to each other, the side arms of each being shaped to form spaced depressions along their outer surfaces and correspondin inward projections along their inner sur aces, the projections of one link extendin into the spaces of the other link to present t e a pearance of a plurality of separate lin connected together, spaces being left at the ends of the outer links for the reception of connecting links.

In testimon whereof I afiix my signature.

ARL SCHRAYSSHUEN.
