ABSTRACT:
A heavy duty vise having a base, a fixed jaw and an upstanding boss formed integrally with the base and movable jaw which has limited reciprocating movement between the boss and the fixed jaw. A threaded hole is formed in the boss and a cylindrical sleeve with cooperating fine threads on its outer diameter extends through the hole. The sleeve extends outwardly to a handle. A rod passes through the sleeve and has a forward end on which the movable jaw is carried. The rod has coarse threads formed thereon which cooperate with coarse threads on the inner diameter of the cylindrical sleeve. The rod also has a handle extending outwardly beyond the sleeve. Rotation of the rod handle provides coarse adjustment of the movable jaw and rotation of the sleeve handle provides fine adjustment of the movable jaw.
