BUCKLE FRAME.

SPECIFICATION forming part of Iietters Patent No. 376,599, dated January 17, 1838.

Application filed October 31, 1887. Serial No. 253,809. (No model.)

To all whom it may concern: I

Be it known that I, GEORGE E. KELsEY, of West Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Buckle-Frames; and I do hereby declare the following, when takenin connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a wire frame embodying the invention; Fig. 2, a wire ring, also embodying the invention; Fig. 3, the meeting ends of the wire preparatory to grooving; Fig. 4, the meeting ends grooved preparatory to receiving the wire; Fig. 5, a transverse section through the groove in the wires; Fig. 6, the connecting-wire detached; Fig. 7, a transverse section through the groove and the connectingwire before closing; Fig. 8, a transverse section through the connecting-wire after closing; Fig. 9, a modification in the formation of the connecting-wire.

This invention relates to an improvement in the manufacture of that class of buckle-frames which are made from'asingle piece of wire bent into the requisite shape, the two ends brought together upon one side and united, the invention being applicable to various shapes, including full circle or ring; and by the term buckle-frame I wish to be understood as including other articles which are adapted to be united in the same manner; and

the invention consists in uniting the ends of the wire of the buckle frame or ring by means of a longitudinal groove in the meeting end portions, with a wire closed in said groove and extending across the joint between the two ends, as more fully hereinafter described.

The buckle-frame, or whatever the article may be, is made from wire of the required length and bent into the requisite shape, as seen in Fig. 3, the two ends a a brought to gether upon one side, so as to abut the one against the other. Then longitudinally upon the surface of the meeting ends a groove, b, is struck, as seen in Figs. 4 and 5. This groove is preferably made by a punch, which will simply displace the metal, as indicated in Fig. 5. Then into the groove b a piece of wire, 0, Fig. 6, is introduced, as seen in Fig. 7, the depth of the groove being such that the wire 0 will come to nearly a central position within, the two ends. Then with suitable dies the sides of the groove are closed over the wire, as seen in Fig. 8 and as indicated in Figs. 1 and 2.

This closing operation brings the outer surface around the grooved portion to substantially its normal size and shape and as shown in Figs. 1 and 2.

Theintrodnced wire a may be simply a straight cylindrical piece of wire, the closing operation being sufficient to cause the metal of the frame to so firmly embrace the wire as to prevent the separation of the ends. The wire, however, may be made notched or serrated, as seen in Fig. 9, which will add strength to the connection. Under this method of securing the two ends of the wire in the formation of the frame or ring 110 soldering or brazing is necessary. The ends of the wire simply abut squarely together, and the operation is one simply and cheaply performed, yet makes an extremely firm connection between the two ends of the wire forming the frame or ring.

I make no claim in this application to the method described, that being the subject of an independent application.

A buckle-frame made from solid wire having the two ends abutting, combined with an independent piece of wire inclosed in the body of said abutting ends and extending across the joint between them, substantially as described.
