Abstract
Apparatus for holding two workpieces, each with respect to a fixed reference location, is disclosed. The apparatus includes a base to which a fixed central jaw member is secured. A clamping assembly which includes a first slide member and a second slide member which are joined by a threaded screw shaft is provided for movement relative to the central jaw member. A biasing means is attached to the first slide member by means of a compression spring assembly and may be either displaced with the first slide assembly or secured to the base. When the biasing means is secured to the base member and the first slide is displaced away therefrom, a biasing force is generated so as to urge the second slide member toward the central jaw to hold a workpiece therebetween. As such, one workpiece may be retained or released prior to another workpiece. Further, the instant construction provides the biasing feature without requiring any increase in overall vise length.
