Abstract
739,748. Bracelets. GOODE, J. A. Jan. 4, 1954 [July 29, 1953], No. 110/54. Class 43. A strap, band or bracelet automatic adjusting link unit comprising link elements pivotally connected for end to end extension or folded longitudinal overlap has a terminal link element slidably connected with and urged to a companion link for length adjustment by coil springs acting in tension and has retaining means for securing the elements in the folded position releasable in response to relative sliding of the terminal and companion links to a predetermined position. As shown, the companion link 10 slides in subsidiary channels formed on the channelled form terminal link 11. The inturned flanges 22 of link 10 and the inturned flanges 19 of link 11 house coiled tension springs 23 held in place at their ends by the shanks of screw heads 25 entering the interiors of the springs, the heads being held by the curled end extensions 24, 26 of the flanges. The flange 31 of the other terminal link 13 of channelled form has a pressed lateral projection 41 of ratchettoothed form in cross-section presenting an inclined face 42 which in the folded position of the links enables the projection to snap past the edges of the flanges 19, 22 to engage its abutment surface 43 with the under face of the flange 22 to prevent withdrawal of the foldable link elements until the slidable link elements 10, 11 are extended against the springs 23 to their maximum amount determined by a projection 38 on the link 10 abutting a lug 39 on link 11 when the projection 41 is located opposite a slot 40 in the flange 19 and is clear of the flange 22 so that the link element 13 can be withdrawn to unfold all the link elements.
