Reissuecl July 28, 1931 PATENT OFFICE EDWIN F. M. SPEIDEL, F CBANSTON, RHODE ISLAND CHAIN Original No. 1,783,552, datedlanuary 13, 1931, Serial No. 483,783, led March 6, 1930. Application for reissue led March 26, 1931.

This invention relates to a chain of the type used for bracelets, watch straps and the like; and has for an obj ect to provide a practical and advantageous construction, each of 6 the links of which is identical, with parts of one link directly connecting with parts of the next link.

A further object of the invention is to provide a construction which may be of plated stock withits inner and outer exposed portions covered with the plate of the stock to enhance and cause it to maintain its appearance. v A further object of the invention is to provide the bracelet of open work construction,

which may be formed by bending and swagin'g the metal into the desired shape.

With these and other objects and advantageous features in view, the-invention con- 3 Isists of a novel arrangement of parts more fully disclosed in the detailed description following, i-n conjunction with the accompanying drawings, and more particularly set forth in the appended claims. v .z5 In the drawings: Y

: It is found desirable to form a bracelet Serial No. 525,579.

chain of such construction as to leave openings therethrough to permit the iiesh to be exposed through the braceletwhen worn upon the arm; and one method of providing such a construct-ion which will be thin and comfortable upon the wrist and one which may have a lated surface on vits exposed parts, I have ent a piece ofplated wire into U-shape, displaced the stock by flattening the cross piece between the U arms and have then suitably notched this flattened portion to provide a recess intowhich the ends of the arms of the next link may rest, thereby forming these arms in parallel relation. The ends of the arms of each link are given aligned pivotal connections within these notches as shown in the drawings by studs fitting within recesses, and the.k studs may be formed upon the iattened portions by leaving suflicient metal when the notch is cut away. The following is a detailed description of the present embodiment of this invention illustrating a preferred means by which these advantageous results may be accomplished.

With reference to the drawings, Figure 6 illustrates a piece of wire folded into U- shape with arms 11 and a cross piece or bar 12. The bar 12 is fiattened by swaging, as illustrated at 13, and at the same time the arms 14 are tapered, as shown in Figure 7 Notches 15 are cut in the body to leave studs 16 which are suitably rounded as at 17, to be receivedin openings 18 adjacent the ends of the tapered arms 14, as illustrated in Figure 9, whereby a chain is formed as illustrated in Figures 1 and 2. Although excellent results are attained in this manner, nevertheless it is to be understod that the broader features of this invention are not limited to these details.

In joining the links together, the arms 14 are at first diverging, as illustrated in Figure 3, which allows them to be snapped by the spring of the stock over the round pins 17, after which they are bent inwardly by suitable operations so as to be in line as illustrated in Figures 1 and 2. By using metal of such nature that it may be swaged into the desired form, there are attained not only the advantages of easy shaping, including ornamentation if desired, but also the characteristic that the metal will, while bendable as in assembling the links, nevertheless tend to retain the form into which itis bent so as to permit a dependable connection without the use of additional parta The flattening of the cross piece :12 to form the body ldisplaces the stock from the top of the link and leaves the bottom 19 smooth, as illustrated in Figure?, in order not to forlnlanyY sharp edges or uneven surface which might be uncomfortable to the arm when worn.

, From the above construction and from Figures 10 and 11, it will be observed that I have preserved the outer plated surface 20 of the wire from which the linkwas'ormed with the only parts exposed being about the notches 15, which are substantially covered by the ends 18 of the Wire extending thereinto. Each of the ends is, however, suitably curved as at 21 to' allow for greater flexibility of the structure.

Various appearances of the chain so constructed may be obtained by variously shaping the cross bar 12 or lthe arms 11 to provide avariety of effects. y

While I have described certain construcr tion forms which embody the principleaof my invention, it is obvious that; other desired changes in arrangement may/be made within the spirit and the scope offthe invention as'deined in the 4appvei'ided claims.

I claim: lf 1. bracelet chain or the like comprisin a series of links, each link generally U-shape and of a single'piece of wire, the cross piece between the arms of the U being, attened to be generally in the plane of the-chain'and having notches cut laterally iiiwardl'y'om its ed e to leave studs, the opposite arms of the U aving recesses to receive said studs and .hingedly' connect the links together.f

A bracelet chain or the like comprising a series of links, each link generally U-shaped Y and of a single piece of metal, the cross piece between the arms of the U beingfilattened to be generally in the plane of the chain and having notches extending laterally inwardly fromV its ed e to leave space for the ends of the arms 0 the next link, and studs and recesses on said parts adapted to hinge-diy connect theJinks together at said notches, said arms being tapered from their ends toward the cross piece and being substantially longer than the extent of said cross-pieces in the direction of the length of the chain to provide substantial openings between successive crossieces.

In testimony whereof, I have signed my name to this specilication this 23rd day of March, 1931.
