Abstract
A setting tool conveniently grips a jewelry finding while providing a person working on the finding with maximum accessibility to it. The setting tool comprises a handle and a lockable cam for moving a pair of clamps radially of the handle axis between opened and closed positions. A variety of interchangeable clamp jaws are provided. The jaws are designed to accommodate a wide range of finding sizes and shapes. In one embodiment, the jaws cooperate with a moveable anvil to hold a pierced type earring. In another embodiment, the jaws have respective tracks that cooperate to hold findings such as pendant wire settings.

A setting tool for gripping selected workpieces comprising:
- a. an elongated handle having first and second ends and a longitudinal axis and a hole therethrough generally coaxial with the longitudinal axis, the handle first end defining a diametral groove;
- b. a pair of clamps comprising respective bases having longitudinal axes and planar undersurfaces slideably received within the handle groove and respective shafts upstandingly attached to the bases;
- c. cam means for holding the clamps within the handle grooves and for radially sliding the clamps to closed and open positions toward and away from each other, respectively, the cam means comprising:
- i. a cam plate located adjacent the handle first end and defining a pair of spiral slots, the cam plate retaining the clamps in the handle groove with the clamp shafts passing through respective cam plate slots;
- and
- ii. a threaded rod attached to the cam plate and extending through the handle hole;
