Abstract
A vise which is constructed of three jaws which are movable to be clamped upon an exterior object, two of the jaws moving in synchronism in respect to another jaw located in a specific position. The movable jaw assemblies are located in an overlapping crossed arrangement. The configuration of the jaws can be altered to grasp not only objects of regular shape, but also objects of irregular shape.
Claims15
A vise comprising:
- a base;
- a first jaw mounted to remain substantially fixed in a specific position upon said base;
- a second jaw assembly movably mounted upon said base;
- a third jaw assembly movably mounted upon said base;
- means for simultaneously moving the jaws of said second and third jaw assemblies toward said first jaw along paths which are spaced from and which substantially form an acute angle with one another over the greater portion of the holding range of said jaws, to thereby clamp an exterior object between said first jaw and the jaws of said second and third jaw assemblies;
- and
- said second and third jaw assemblies overlapping each other in a crossed configuration.

- and
- said second jaw assembly including a second jaw, said third jaw assembly including a third jaw, both said second jaw and said third jaw being pivotally mounted in respect to its respective said assembly, both said second jaw and said third jaw including at least three sides with each side being of a different configuration, whereby a particular configurated side may be employed to facilitate clamping to a particular configuration of an exterior object;
- and wherein each of said three jaws includes means for presenting an angled work gripping surface having at least two planes perpendicular to the plane extending through said three jaws, and each of said three jaws also includes means for presenting another angled work-gripping surface having at least two angled planes having a line of intersection extending substantially parallel to the plane extending through said three jaws, whereby elongated objects of circular configuration may be firmly held in orientations perpendicular to or parallel to the plane extending through said three jaws.
