661,609. Bracelets. CORNU, A. May 9 1949, No. 12290/49. Class 43. [Also in Group XXV] An expanding clasp for a bracelet comprises a central link 31 to which two shorter links 32 are hinged, the latter which are also hinged to the ends of the bracelet 37 being foldable over the central link to be releasably held by the engagement of a spring-urged latch member on the central link with another part of the clasp, release being effected by means of a pusher. A latch housing 39, Fig. 2, secured to the link 31, contains two slides 38, each having two integral latches 38a which snap over inwardly projecting edges 34a of the bracelet-cord housings 34 to hold the links folded. The slides 38 are urged apart by a spring which acts on rounded parts 38b integral with, and located between, the latches 38a of each slide, outward movement of the slides being limited by inturned edges 31a of the links 31. Pressure on the part 38b disengages the latches from the edges 34a. The shorter links 32 at their other ends are pivoted at 35 to the bracelet-cord housings 34 in each of which one end of a cord bracelet 37 is retained by a pivoted claw 36. The link 31, Fig. 4, is formed at each end with two arms 31a which are bent round a pin 33, the latter being engaged by a hook 32a formed at the end of each short link 32 ; inturned edges 32b of the latter guide a sliding bar 41 which closes the entrance to the associated hook.
