Abstract
A three-way vise of this invention includes a pair of workpiece clamping jaws mounted on a frame in substantially perpendicular relation to one another, and a pivotable clamping jaw is supported on the frame for applying a clamping force onto the workpiece in a direction angularly inclined to the other jaws. An adjustable jaw pressing device is provided for selectively urging the pivotable clamping jaw into engagement with the workpiece with increased clamping force after the three jaws are initially engaged with the workpiece.
Claims5
A workpiece clamping vise comprising a frame, a fixed jaw secured to the frame, a base and a sliding jaw mounted on the frame for sliding movement toward and away from the fixed jaw, a rigid angularly inclined arm secured to and projecting from the base toward said fixed jaw, a clamping jaw disposed in overlying relation to the sliding jaw and pivotally supported on the base for swinging movement toward and away from the fixed jaw, and jaw pressing means mounted on the rigid arm of the base for selectively pressing the clamping jaw toward the fixed and sliding jaws to positively lock the jaws and the workpiece in relation to the frame.
