A TTOR/VEYS UNITED STATES PATENT OFFICE.
BERNARD LEVY, OF RIVERSIDE, NEW JERSEY, AS-SIGNOR TO THE KEYSTONE WATCH CASE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENN- SYLVANIA.
EXPANSION-BRACELET LINKS.
Application filed July 9, 1915.
To all whom 2'25 may concern:
Be it known that I, BERNARD LEVY, a citizen of the United States, and a resident of Riverside, in the county of Burlington and State of New Jersey, have made and invented certain new and useful Improvements in Expansion-Bracelet Links, of which the following is a specification.
This invention relates to expansion bracelets, and more particularly to the construction of the guide link, the object of the invention being to provide a guide link of the solderless type, which may be easily and economically manufactured, and wherein the completed article will possess a strength capable of withstanding strains far in excess of those to which it will be ordinarily subjected.
A further object is to provide a slide link made up of trough-shaped members connected at their one ends by an integral post, and having overlapping curved extensions at their remote extremities, the latter being secured together by a hollow rivet, thus rendering unnecessary the bending of these extensions, and providing for a built-up post of double the thickness of each extension, and thereby defining a guide link of neat appearance, strong and rugged in construction, and one that may be economically manufactured, and with but little manual labor involved.
Other objects and advantages will further appear, as hereinafter set forth.
The preferred embodiment of my invention is disclosed in the accompanying drawings, wherein Figure 1 is a view in side elevatlon of a portion of an expansion bracelet made up of a plurality of links, each of which embodies the characteristic features of my 1nvention. Fig. 2 is a view in longitudinal vertical section of a link and portions of adjacent links, the view being on an enlarged scale. Fig. 3 is a view in perspective of a guide link, the slide link therefor be1ng omitted in order that the features of the present invention may be more clearly illustrated. Fig. 4 is a view in section taken through the top and bottom of the troughshaped sides of the guide link and illustrating the same in the process of format on. Fig. 5 is a view in longitudinal section similar to the foregoing after the trough-shaped sides have been bent so as to bring the end Specification of Letters Patent.

extensions into overlapping relation, and after the hollow rivet has been secured thereto. Fig. 6 is a view in section taken on the line 66 of Fig. 5, illustrating the curved cross-section of the extensions Whereby the trough-shaped members are held in proper 'alinenient prior to the riveting thereof.
Referring specifically to the several views, the guide link is stamped or formed from a blank, and includes the trough- shaped sides 10 and 11, the one ends of which are connected by the integral post 12, the material of which the post 12 is formed originally occupying the central portion of the blank, and about which the said trough-shaped sides are folded.
The opposite and free ends of the troughshaped sides of the guide link are provided with the extensions 13 and 14. These extensions are curved in cross-section, as illustrated in Fig. 6, and are formed With complementary surfaces, so that the outlying extension 13 is adapted toreceive the inner extension 14 therein. Thus, as the troughshaped sides 10 and 11 of the guide link are brought together, the extensions 13 and 14 are brought into overlapped relation, and hold the said trough-shaped sides in proper and spaced position, until such time as a positive and permanent securement between the extensions is effected.
In securing the extensions 13 and 14 together, it has heretofore been the practice to bend the sides of the one around the other, the disadvantages of which reside in the large amount of manual labor necessary to produce such bending and, furthermore, a permanent juncture is not effected, as it may happen that portions of the clothing may catch in these bent projections and result in the separation of the extensions. In order to overcome these difliculties, I provide the extensions 13, 14 with corresponding openings 15, which are adapted to register when the trough-shaped sides are bent into proper spaced relation. A hollow rivet 16 is inserted through the registering openings 15, and by the use of a suitable instrument or tool the side walls thereof are spread and the extensions rigidly and permanently secured together. The riveting of the extensions may thus be accomplished with little labor, and insuring a permanent juncture therebetween. The innermost extension 1i is ofiset slightly with relation to the end of the trough-shaped side 11 so as to receive the end of the extension 13 against the shoulder, as thus formed, which in connection with the transverse curvature of the extensions, holds the openings 15 in exact alinement, allowing their securement by the rivet to be easily and quickly efiected.
A slide link 17 is assembled within the guide link prior to the completion of the latter, and may partake of any suitable and desirable form, and co-acting with which, as illustrated in Fig. 2, is the coil spring 18. A number of the completed links, as thus constructed, are assembled together and form an eXp-ansible bracelet or analogous article of jewelry.
hat I claim is:
1. An article of the class described comprising a guide link including a pair of confronting trough-shaped members connected at their one end by an integral bridge, the
remote ends of said trough-shaped members provided with overlapping extensions correspondingly curved in a transverse plane and a rivet extending through said extensions, and a slide link associated with the foregoing.
2. An article of the class described comprising a guide link including a pair of confronting trough-shaped members connected at their one end by an integral bridge, the remote ends of said trough-shaped members provided with overlapping extensions correspondingly curved in a transverse plane, one of said extensions offset and provided with a shoulder receiving the other of said extensions thereagainst, a rivet extending through said extensions and a slide link associated with the foregoing.
Signed at Riverside, in the county of Burlington and State of New Jersey, this 7 day of July, A. D. 1915.
BERNARD LEVY.
