Abstract: This disclosure is directed to expansible linkages for expansible wrist watch bracelets, identification bracelets and similar articles which permit the retail jeweler to quickly and easily adjust the length of a bracelet to fit different size wrists of customers.The bracelet includes two sections of expansible linkages of each of which has a row of top links, a row of bottom links, means interconnecting the links of each row with the links of the other row to provide longitudinal displacement of the links relative to each other from contracted to expanded positions and vice versa. A channel shaped outer member has a series of aligned perforations extending through its side walls. First spring pin means connected to one end of one of the expansible sections has the outer ends of its trunions extending into a first selected pair of the aligned perforations.

Abstract: Watch bands, bracelets, belts or similar articles which include strip means having one end adapted to be connected to a buckle. The other end of the strip means includes a series of longitudinally spaced transverse apertures. Each product also includes generally flat spring means and a buckle, one end of which includes pivot means for connecting that end of the buckle to said end of the strip means. The pivot means includes at least a portion which is of greater width than thickness. The other end of the buckle includes a cross piece having a tongue secured thereto for engagement selectively with one of the transverse apertures of the strip means when the buckle is in its closed position.

Abstract: This disclosure is directed to expansible linkages for use in the manufacture of expansible bands such as wrist watchbands, identification bracelets, and other articles of jewelry, the sides of which when viewed from the top are provided with attractive configurations, for example, tapered from their ends toward their center portions or vice versa. It is also directed to novel methods of making such expansible linkages.The expansible linkage includes two rows of links and resilient means associated with the links for returning them from expanded to contracted positions. It also includes a series of ornamental top shells attached to the top links. The ends of the top shells extend outwardly from the ends of at least a majority of the top links. Solid inserts are positioned within the outwardly extending portions of the top shells and the outer ends of the combined top shells and inserts are machined to provide any desired configuration to the sides of the linkage when the linkage is viewed from the top.
