Abstract:

A link chain to be used as a watch band, bracelet, or other item of jewelry. The chain includes a string of readily detachable link elements to permit the length of the chain to be quickly and easily adjusted, as desired, by removing or adding link elements at any point along the chain. Each link element consists of a journal link-half permanently hinged to an associated bearing link-half. The journal link-half of each link element includes a solid pintle having two ends, one end being constructed and arranged to be rotatably received in a permanently closed bearing and the other end being constructed and arranged to be rotatably received in a selectively openable bearing at an end of the bearing link-half of an immediately adjacent link element whereby to hingedly join the link elements. The selectively openable bearing has a manually operable closure shiftable between a first and a second position and biased to the first of these positions. In the first position, the closure bridges or caps a cradle to form a bearing so as to captively retain the other end of the pintle of the adjacent link element positioned in the bearing.
