JOHN S. PALMER, OF PROVIDENCE, RHODE ISLAND.

CONSTRUCTING BRACELETS, &amp;c.

Specification forming part of Letters Patent No. 31,735, dated March 19, 1861; Reissued September 9, 1873, No. 5,571.

To dll whom it may concern:

Be it known that I, John S. Palmer, of Providence, in the county of Providence and State of Rhode Island, nave invented a new 5 and useful improvement in constructing bracelets, which is also applicable in constructing .finger-rings, ear-hoops, and some other articles of jewelry; and I do hereby declare that the following is a full, clear, 10 and exact description thereof, reference being had to the annexed drawings, and to the letters of reference marked thereon, in which—

Figure 1, is a perspective view of my im15 proved bracelet. Fig. 2, is a front view and section of the same. Figs. 3, 4, 5, &amp;c. are details which are referred to in the course of the description.

Similar letters of reference denote like 20 parts in all the figures.

It has formerly been the practice to form the front or ornamental plate of such bracelets in one piece, with the edges turned at right angles therefrom, after which the su25 perfluous stock is trimmed off, and the said edge soldered to a flat plate or lining, and the superfluous stock trimmed therefrom. The die which stamps or forms the ornamental plate is expensive and if a portion 30 of the design is defaced by accident or otherwise., the whole. die is rendered . worthless. Again as each die produces but one design, a number of such dies are necessary to produce a variety of patterns or styles. In 35 addition to this the trimming off the edge of the lining, leaves the baser metal exposed, (plated stock being generally used,) which coining in contact with the wrist of the wearer, forms an oxid which penetrates the 40 soldered joint and separates the lining from the front.

My invention consists in turning over the edges of the foundation plate, to form an overlying lip, (or slide,) upon each edge of 45 the outside of the bracelet, which forms a smooth round edge, and serves to support and retain certain ornamental work, composed, of a number of metal plates, of designs in bas-relief, or chased work, or suit50 able plates containing hair work, precious stones, or miniatures, whereby different combinations of ornamental work may be produced upon one foundation plate, and thus, a great variety of styles, at much less expense than by the ordinary process of 55 manufacture.

To enable others skilled in the art to make and use of my invention I will proceed to describe the construction and operation.

A strip of metal of the width shown in 60 Fig. 5, No. 1, is passed through a set of rolls, which turn the edges as shown in No. 2, and again through another set of rolls, which turn the edges as shown in No. 3,—tlie form of the rolls, and the mode of operation being 65 sufficiently familiar to workers in sheet metal to require no description here. The turning or rolling the edges of-similar rings of sheet metal, is also generally practiced to stiffen such rings, and for that purpose is 70 well.known, and I do not pretend is my invention.

The above stock is formed into a. ring or oval, composed of two pieces, which are united at a, Fig. 1, in a hinge joint and at δ, 75 by a catch or spring fastening.

Fig. 4, represents an. ornamental plate of die work in bas-relief, having projecting lips (or edges) c, c, at each end, and a ridge or bead i, which overlaps the opposite thin 80 edge, s, upon, the adjoining plate, and hides the intervening space, as shown in Fig. 2. /, Fig. 2, represents a metal plate having openings therein, beneath which (plate) is placed braided, hair-work I, which is visible 85 through the said'opening, and which by contrast with the polished metal plate produces a highly ornamental effect. These ornaments are slid beneath the lips e, e, of the foundation plate, in their proper order and 90 position, the lips e, e, overlapping the lips c, c, of the plates B, B, and the beads ^ overlying the thin edges s, of the adjoining plate. (Figs. .2. and ,3.) The plate inserted next •to the joints a, and δ, of the bracelet, Figs. 95 1, and .2, is secured in its place, to the foundation plate by a rivet passing through both, and thus the several ornaments are permanently secured therein. Should the bracelet be bent or broken, it will only be 100 necessary to remove the rivets, when the ornaments may be readily removed, and the injured parts repaired, or new parts substituted for those which are broken or defaced.

It will be observed that a multiplicity of 105 designs in bas-relief or mountings of precious stones, shell, and hair work, etc., may be inserted and combined upon one bracelet,

31,735 and every different combination produces a different” style or pattern, and in such a manner that no soldering is required.

The dies which stamp the ornamental 5 plates are inexpensive compared with those for stamping an entire front or outer surface, and if one is injured, another of a like, or of a different design may be made to take its place at a trifling expense.

In the construction of finger-rings, ear hoops, and other articles upon this principle, it will only be necessary to vary the size and form of the foundation plate and ornaments, to combine a variety of designs and thus 15 produce numerous styles of such articles.

I do not claim turning over the edge of a ring of sheet metal by means of rolls, for the purpose of forming a rounded edge, or for stiffening such ring, as this is well known and not my invention. 20
