Abstract
A springless jewelry finding (25) includes an hinge plate (26) and an ear-wire (28) having one marginal end portion (34) secured to the hinge plate, having an intermediate arcuate portion (35) and having a distal marginal end portion (36). A lever-paddle (29) has one marginal end portion (38) pivotally mounted on the hinge and has another marginal end portion (39) mounted for arcuate movement toward and away from the ear-wire distal marginal end portion. The lever-paddle other marginal end portion has a concave surface that is adapted to selectively embrace the ear-wire distal marginal end portion and has a detent (40) that is so configured and dimensioned with respect to the ear-wire distal marginal end portion as to require that the ear-wire distal marginal end portion be forcibly passed through the detent as the lever-paddle is moved between opened and closed positions relative to the ear-wire. When the lever-paddle is in its closed position, the detent will prevent the lever-paddle other marginal end portion from freely moving away from the ear-wire distal marginal end portion.
