12 Claims.

The invention relates to the manufacture of jewelry, and aims to present a method particularly applicable to the manufacture of one-piece filigree bracelets. An important purpose is also to present an improved product produced by this method.

It is an important attainment of the invention that extremely delicate filigree work may be quickly assembled in a durable bracelet of excellent workmanship at an extremely low cost. It is also an important object to enable the formation of a one-piece bracelet and fastening in a novel way.

In the jewelry trade a stockfiligree strip known as pierced stock is familiar, one well known form is made in short strips, two of which end to end may be utilized as a continuous ornamental feature of a bracelet of any kind. Such strips are used in two-piece bracelets, and also in onepiece spring bracelets. Customarily this pierced metal is soldered to a support or body part, carring the necessary hinges and catches, and in some cases a band is formed of the pierced stock with overlapping ends, adapted to spring into closed bracelet form with ends slightly overlapped, and maintained in closed form by its inherent resiliency, by which it opposes movement from closed position with the ends overlapped.

It is an important purpose of my invention to enable the utilization of this stock strip in a novel way, minimizing labor operations, and enabling the production of a bracelet of substantial appearance utilizing the thin pierced metal strip as its embellishment. It is also an aim to form a novel means for closing such a bracelet without requiring assembly of separate fastenings or parts such as tongues and sockets, spring catches, latches or the like.

Additional objects, advantages and features of invention reside in the methods of manipulation and sequence of steps as hereinafter recited, and in the nature of the product as more particularly set forth hereinafter and shown in the accompany drawing, wherein, p

' In forming a bracelet by my method, I first produce a stock channel form 10 shown in Figures l and 2,. which operation is preferably carried out by machine into which simple, fiat ductile metal ribbon stock is fed, the edges of which are thereby turned in, as at 11. This is next cut to the form shown in Figure 4 although it would preferably be blanked in suitable dies whereby a frame 12 is formed having two gallery bars 13 at the sides connected by intermediate fiat cross bars 14 and two end cross bars 15, at the back side. The bars 18 are each substantially U- shaped in cross section, having

flanges

16 and 17 at bottom and top, respectively, of the channel stock, but the back flange 16 is somewhat broader than the top one 17, in order to gain some strength in the piece Without creating a too heavy appearance in the channel body, as will appear, and also to afford a broad, smooth wrist-engaging surface on the finished piece.

In the blanking, three transversely spaced hinge ears 18 are formed projecting longitudinally at one end of the body, a somewhat broader central longitudinal tongue 19 with rounded end being formed at the other end, and two finishing cars 20' at respective sides of this tongue, on the edge of the blank. The ears and tongue spring from the outer sides of the bars 15. These ears 2% serve as channel closers or retainers for the inserted pierced work, as will appear. The ears 18 also serve a similar purpose at the opposite end of the piece. Two of the cars 18 have their outer lateral sides flush with the external surface of the respective bars 18, and all are turned in cylindrically on the same side of the channel with the flange 17 so as to form hinge knuckles lying snugly against the ends of these flanges and flush with the top faces thereof.

I also form separately by familiar practice the pierced metal or other ornamental insert strip 21, which may be made of any desired length, but commonly, in order to save expense in making dies and forms, it is made in half lengths, so that two will equal the maximum circumferential measurement of an ordinary bracelet body. It is of a thickness slightly less than the space between the

flanges

16 and 17, and of a width to slide easily into the channel under the flanges 17 by manual insertion. In the body blank as shown there are three intermediate cross bars 14 equally spaced from each other and similarly spaced from the end cross bars 15. Before insertion, the two insert strips are trimmed equally to aggregate the length of the piece, so that their meeting ends will lie over the central cross bar 14, and one is notched at 22, on the end to afford a clearance under the tongue 19. The inserts are now inserted, and the cars 20 turned upward and inward over the insert end. These ears are each formed with a short part 23 next the respective bars 13 and longer parts 24 at their inner sides, the short parts when turned up lying flush with the tops of the flanges 1'7 and the longer parts being turned in over the end of the insert so as to form short end flanges 25 with the appearance of a mitered continuation of the flanges 17. The ears 26 are spaced slightly from the tongue 19, and the latter is turned upward and recurved inward over the outer face of the insert to form a hook 26, the recurved part projecting slightly from the end of the piece. The bill 27 of the hook is slightly curved upward.

The assembly now comprises the main piece or body of the bracelet. It is in a form to be conveniently plated if not of solid precious metal, and such plating is carried out in accordance with familiar practices, serving to make the junction of the two inserts continuous in appearance. The piece may be buffed by automatic machines on an automatic feeding work holder while in the fiat form as assembled, contributing further to economy in manufacture. After bufiing, the piece is bent to the desired shape and size to receive the wrist of a wearer, forming a G-spring with a substantial opening between its ends. For closing the bracelet and connecting the ends of the piece formed as above described, an ornament fastener 30 is provided which may be one of a multiplicity of different designs, all however, having hinge knuckles 31 at one side to be set between the knuckles formed of the cars 13 and secured by a hinge pin 32 engaged through all. The ornament includes a frame piece 37 having the knuckles 31 thereon, and having also adjacent the opposite side of the frame from the knuckles a bar 33 looped or otherwise formed properly to pass under the hook 26 when the bracelet is compressed to less than normal size and allowed to spring open again. As the fastenor 30 does not require a very great extent of movement, the knuckles thereon may be well under the ornament, but preferably slightly offset below the fastener. The bar '53 is also preferably located underneath the ornament so as to not only be concealed, but so as to hold the ornament over and conceal a substantial part of the hook 26.

The sizeof the bracelet may be governed by the width of the ornament, or by forming the blanks of the body in various lengths. The 0rnament 30 preferably is of a form to completely cover both ends of the main piece.

The ends of the inserts may be soldered together if desired to add to the strength of the article and improve its spring action, although the location of the central cross bar 14 is thought to obviate need for this.

In another method a body strip of plain flat stock 40 is formed with the necessary hinge cars '41 at one end, while at the other there are formed the tongue 42 and edging ears 43; and a roll edge 44 is formed along the entire length at each side, the space between these roll edges being the same as the width of the pierced stock. The ears 43 are plain and are turned in as a transverse continuation of the roll edge. The pierced stock is then trimmed at the ends to fit snugly upon the outer face of the stock 40 between the rolls 44 and end knuckles and rolls 43, being soldered in place after the knuckles are formed. The piece is then formed to the necessary C-spring shape and the fastening ornament 30 attached as before.

The openings in the base stock may be varied for ornamental and other effects, and may be omitted.

A plain fiat base stock strip 45 may be used without the roll edge at the sides, but having the hinge ears and tongue only, at the ends, and the pierced stock soldered to the outer face thereof, the forming and assembly otherwise being as before described (see Fig. 14).

The gallery edged stock may be used to form an ordinary one-piece spring bracelet, without fastening, if desired.
