Floating jaw assembly for use with machinist vises

The vise assembly of claim 1, wherein the floating jaw assembly is an accessory that can be attached to an existing vise assembly.3. The vise assembly of claim 1 or 2 wherein the floating jaw assembly further comprises a means of forcing the at least one floating jaw plate downward and securely against the at least one way of the vise assembly.

The vise assembly of claim 3, wherein the means of forcing the at least floating jaw plate downward and securely against the at least one way of the vise assembly comprises a bracket and screw clamp assembly comprising:

• a. A bracket having at least one opening corresponding and positioned to receive the at least one mounting pin and a lower holding means for slidably engaging with the vise base along the longitudinal axis of the vise and for securely holding the bracket against the vise base;
• and
• b. A screw positioned to interact with a threaded opening in the bracket in a manner to force the at least one mounting pin downward and, in cooperation with the at least one mounting pin,the at least one floating jaw plate toward the vise base when the screw is turned downward.

The vise assembly of claim 3, wherein the means of forcing the at least one floating jaw plate downward and securely against the at least one way of the vise assembly comprises a cam and lever assembly that forces the at least one mounting pin downward and at least one floating jaw plate securely against ways when cam and lever assembly is engaged and relaxes said forces on at least one mounting pin and at least one floating jaw plate when not engaged.

An assembly comprising two or less components that secure and release at least one floating jaw plate to a vise assembly.

A machinist vise assembly capable of holding a plurality of individual workpieces, and comprising a base with at least one vise way, a fixed jaw mounted on the at least one vise way, at least one movable jaw slidably mounted on the at least one vise way to move toward and away from the fixed jaw on a longitudinal axis in such a manner that at least one workpiece can be securely held between the fixed jaw and the at least one movable jaw, and a mechanism for moving the movable jaw toward and away from the fixed jaw to clamp and unclamp workpieces;

• and at least one floating jaw assembly comprising a floating jaw plate and two or less components that when engaged force and securely hold at least one floating jaw plate to the vise assembly and when said two or less components are not engaged allow for adjustable movement of the at least one floating jaw assembly along the longitudinal axis of the vise assembly and for articulated movement of the at least one floating jaw assembly in a plane substantially parallel with the at least one vise way of the vise assembly and about a vertical axis perpendicular with the at least one vise way of the vise assembly so that the at least one floating jaw assembly can, in cooperation with adjoining jaw or the adjoining at least one movable jaw and or the at least one floating jaw assembly adjust to and securely hold workpieces.
