Claim:
A vise accessory intended to mount on a conventional vise without modification and provide the capability to grasp irregularly shaped objects, comprising: a first accessory bracket for the stationary jaw mounted by means of both the threaded mounting holes provided in conventional vise jaw faces, as well as, a supporting beam of adjustable length extending downward from the rear of the first accessory bracket and resting on a rear portion of the vise and having a flat jaw face surface in front fashioned in such a way as to allow the first accessory bracket to be used as a conventional vise jaw face; and a second accessory bracket for mounting on the movable jaw and mounted by means of both the threaded mounting holes provided in conventional vise jaw faces, as well as an underhung supporting wedge arrangement where the wedge is axially driven into the interstitial space between the movable jaw bracket and the vise by means of a screw so as to provide a secure fit and the capacity to withstand the forces generated by the clamping action of the vise thus configured and having a flat jaw face surface in front fashioned in such a way as to allow the second accessory bracket to be used as a conventional vise jaw face; and a pair of accessory jaws mounted to the above brackets each consisting of a array of spring loaded pins protruding through a plate arranged and supported in a manner such that they can individually deflect and thereby form a grasping engagement of an irregularly shaped work piece when the vise jaws are closed.
