Abstract
The locking system for a precision vise includes a slotted base with downwardly facing serrations engaged by a locking block having upwardly facing serrations with the locking block being connected to the lower end of a bolt oriented generally at a 45.degree. angle and extending upwardly through the slot and a passageway in the movable jaw to clamp the movable jaw in adjusted position. The bolt includes a threaded upper end with a nut thereon and a flange or shoulder intermediate the ends engaged by light spring which also engages a downwardly facing surface on the movable jaw to move the locking block downwardly in order to assure that the serrations on the locking block will not engage the serrations on the base when the nut on the locking bolt is rotated to release the movable jaw. The bottom surface of the base is recessed with the serrations being in the downwardly facing upper surface of the recess and a slotted retaining plate is provided flush with the bottom surface of the base to retain the locking block when the movable jaw is released and being adjusted.
