  • Patent number: 5133195
    Abstract: An improvement in an article of jewelry of the type in which an ornament, such as a jeweled setting, is selectively secured to or released from a support, such as a ring, merely by sliding a spline on the jeweled setting longitudinally into or out of a groove in a bridge coupled to the support, the bridge being coupled to the support solely by hinged connections at coupling locations so that the bridge is isolated from bending moments in the support at the coupling locations and the sliding movement is not impeded, the improvement including a latch for latching to secure the jeweled setting in place on the bridge and selective unlatching for releasing the jeweled setting from the bridge.
