Abstract

A machine vise for use in clamping and holding a work product having parallel and non-parallel sides. The vise is constructed with a pair of pivotal movable jaws positioned between two fixed outer jaws in the preferred embodiment. A pair of movable wedges are positioned between the movable jaws and move the jaws towards the fixed jaws. Both the movable jaws as well as the wedge blocks are mounted to pivot independently of each other. A spring bias is positioned between the movable jaws to bias the jaw action. The vise may be constructed in a single wedge configuration and may be mounted with other similar vise configurations to provide a multiple vise configuration.
