GEORGE BURCH, OF NEWARK, NEW JERSEY.

Letters Patent No. 91,081, dated June 8, 1869.

IMPROVEMENT INEHE MANUFACTURE OI BRACELETS.

The Schedule referred to in them Letters Patent and making part of the same.

To allwlwm it may concern Be it known that I, GEORGE Bcncrr, of the city of Newark, in the county of Essex, and State of New Jersey, have made certain Improvements in Bracelets; and declare the following, taken in connection with the accompanying drawings, to be a full,-clear, and exactdescriptionof the same.

The nature of my improvement consists in the construction of bracelets, rings, and similar forms ram 3' single strip of metal with edges rounded inwardly, and in the adaptation of dies to the hitherto unattained object of forming, from a single piece of metal, in one process, perfect rohnd edges to oval o r elliptical bracelets or to round finger-rings.

livery jeweller is aware of the unprofitableness of attempts to bend a straight piece of metal with round turned edges intoround, oval, or elliptical forms, it being next to impossible to preserve or attain a smooth beadmg .on the edges when turned or bent; therefore, when round-edged bracelets are desired, they are made in parts and soldered together.

To attain the object of rounding from a single piece .of metal, the edges of bracelets or of similar forms, a.

metal being between the two.

formed into a ling, and the ends soldered together and placed in the case or form, and the'case is bolted securely.

Dies are fitted with nicety to the inside of the case or form, one above, and the other below, the strip of Around the edge of the face of thedie a recess, nearly semicircular in its depth, and of the width necessary to form the head or round of the desired size-ismadeendis shown at .Figure 2, and the same in section at Figure 4.

Pressure is applied to the dies, which has to be nicely. equalized, the force turning the edges of the strip as nearly round as possible by means of the recess in the edges of the dies, as shown in the section 6 of the bracelet, Figure 1.

I do notclaim the means simply by which the desired object is attained.

What I claim, and desire to secure, is-

1. The construction of bracelets, rings, or similar. forms from a single strip of metal, with edges rounded inwardly, substantially in the manner'set forth.

, 2. The combination of the dies, constructed as described, with a case, A, or its equivalent, for the pure poses'set forth.
