This butit will be understood that the method and operation also closes any gaps'or seams which the resulting product may be varied in opera may appear at 10 between the wide ends 9 v tion or design to suit particular purposes and the relatively narrow sides 8 of the link,

without departing from the essence of my inand these seams are scarcely discernible in the finished'link in Fig. 8, appearing only as faint lines 13.

It will be observed that the projections 9 are formed at spaced intervals intermediate the ends of the strip 6, and that the ends 8 of the strip are bent into abutting relation at one side of the link, as indicated at 11. It is also apparent that the unfinished surfaces of intermediate connectors 12 (Figs l and 5) customarily employed for this purpose surround the side members 8 of the interconnected links. In accordance with common practice the connectors 12 may comprise a flat piece ofvmetal bent over and encircling the adjoining sides of adjacent links of the bracelet, and in the present instance the transverse dimension of the connector preferably approximately equal .to the corresponding dimension of the openin 14 in the link.

From the forecoing it is apparent that my improved process consists essentially 1n the formation of an open-centered braceletlink shaped from a single length of metal by cutting longitudinally spaced, substantially rectangular recesses 7 from one side of the metal strip to provide the projections 9 spaced from each other and from the ends of the strip, and

by thence bending the strip transversely about said projections to bring its ends into opposed or abutting relationship, as at 11, and to carry the narrow or side portions 8 and 8 into jLlX- taposition with the rough edges of the projections or wide ends 9. The further step of lightly rolling or swaging the surfaces of thelink to flatten its corners and to close the seams 13 at the corners of the central opening 14% (Fig. while optional, is a desirable and recommended final step'of the process and results in the production of a finished link of pleasing contour and appearance.

The completed link is thus extremelyeasy and economical to manufacture, yet it is substantially as durable in use and as attractive in appearance as a link fabricated by more expensive methods. As above explained, when the links are interconnectedby intermediate members surrounding their adjoining side portions, the rough edges and the joint between the abutting ends of the metal unequally redistributingthe plating material.

A method of making a bracelet link which comprises cutting longitudinally spaced recesses in one side of a metal strip to provide spaced projections disposed intermediate the ends of the strip, and bending the strip. transversely about the said projections to bring theends of thestrip into opposled relation at oneside ofan open-centered lin r.

A method of making a bracelet link which comprises cutting longitudinally spaced recesses in one side of a metal strip to provide spaced projections disposed intermediate the ends of the strip, bending the strip transversely, about the said projections to bring the ends of the strip into opposed relation at one side of an open-centered link, and swaging the surfaces of the'linkto flatten the corners thereof.

8. A method of making a bracelet link from a straight strip of metal, which comprises cutting longitudinally spaced, substantially rectangular recesses in one side of the strip to provide a pair of similar rectangular projections spaced from each other and from the ends of'the-strip, and bending the strip transversely, about, said projections to bring its ends into abutting relation at one side of an open-centered link with the side edges .of the said projections juxtaposed to the inner surfaces of the side portions of the link."
