(under subclass 86) Device including three work gripping elements, each movable in substantially the same plane and mutually adjustable* and/or actuable*, to hold the same workpiece or workpieces.
(1) Note. While the elements do not move in couples they do coact and are therefore considered jaws*.
(2) Note. See subclass 289 (2) Note and JAW* (B) with reference to a disclosed, but unclaimed, work-underlying-support element constituting one of the three work gripping elements. A patent to a holder with a jaw couple which can hold work without a disclosed, but not claimed, work-underlying-support is therefore not placed in this subclass.
(3) Note. See JAW* (C) and (D) for the locus of patents with
respect to plural jaw elements all coacting with a multi-configured work engaging member.
