171,477. Brand, L. Aug, 14, 1920. Bracelets; necklaces.-A fastening for neck. laces, bracelets, &c. consists of two members A and B which are formed from solid or hollow blocks, and when engaged with each other by securing means on the flat faces a and b, appears like the rest of the links. The securing means may be a stud and slot as in Fig. 2, or a pair of lateral flanges h on one member H fitting into a pair of lateral grooves g in the other member G, as shown in the form illustrated in Fig. 4. To prevent accidental unfastening, one end of the fastening link is connected to the next link by a cranked joint, the arm E of which abuts against the flat ends of the socket member, and the other arm e assumes a position symmetrical with the joint F at the other side.
