ABSTRACT:
This invention pertains to an auxiliary jaw which is adapted to be affixed to a movable member and as this movable member is advanced to and from a workpiece to grip and hold this workpiece when and while the auxiliary jaw is advanced. This auxiliary jaw includes a pivoted jaw member carried by a support member which is preferably secured to the movable member by cap screws. The pivoted jaw member engages the surface portion of the workpiece in local areas as it exerts a gripping force urges the workpiece toward the support surface. Three configurations of jaw assemblies are shown. Each has a pivoted jaw with one configuration supporting the workpiece above the pivoted jaw. In a second configuration the support as a pin means is below the pivoted jaw and in yet a third configuration the pivoted jaws are movable toward and to a support disk for multiple workpieces. Soft jaws, hardened jaws and bias means may be used to bring the pivoted jaw to the desired condition. A cap screw retains the pivoted jaw to the support member and the pivot is at and on the upper extent of the support. This auxiliary jaw may be attached to any work table but is usually used with a chuck body on a lathe. The movable member is conventionally a T-member slidable in a T-slot in the chuck body. This auxiliary jaw may be used with independent jaws or self-centering jaws moved by a scroll plate.
