DEFINITION

Classification: 269/134

(under subclass 86) Device including means to effect an additional clamping or holding action on work with respect to an underlying work supporting member(s) which additional clamping action is derived from jaw actuating* means or jaw movement, generally parallel to the supporting surface of said member.

(1) Note. Inherent in all rockable or pivotal jaw holding devices, depending on the relative angular position of the parts, is a similar force-component urging work transversely of the pivot or axis. However, unless the device includes (a) specific work underlying support means and (b) the jaw actuating means (or jaw movement) is generally parallel to said surface, patents to such device will not be placed here (subclass 134) but elsewhere in the schedule on the basis of other appropriate features.
