Abstract
An improved machine vise, particularly well suited for use on milling machines and the like, having an improved arrangement for securely holding workpieces of irregular shapes or several different, diversely sized workpieces simultaneously. The vise is provided with a fixed jaw and two movable jaws mounted in a side by side relationship such that each jaw is free to move back and forth into and out of a gripping relationship with the object being clamped. The two movable jaws are yoke driven on a shaft such that a single forward thrust of the yoke exerts a forward and downward pressure to move both jaws forward while at the same time allowing for a translational motion between said adjacent jaws. These jaws can thus simultaneously grip and secure individual workpieces of different dimensions or differently sized portions or cross-sections of the same workpiece. Each jaw may also be provided with individually mounted fingers that pivot into the best gripping relationship with the object being clamped. A multiplicity of gripping fingers are thereby set in gripping engagement with a workpiece by a single operation of the vise. An arrangement for exerting a downward pressure on the yok…
