Abstract
Abstract A quick release tool post for machine tools including a body having a pair of adjacent side faces, a recess formed in each of said adjacent faces for selectively receiving a tool holder, a clamp member at the intersection of the two adjacent faces and cooperating with the recesses for clamping a tool holder in at least one of the recesses, the clamp including a portion having a longitudinal axis substantially bisecting the angle formed by the two adjacent faces and passing through the body of the tool post, a handle associated with the clamp for imparting reciprocatory motion to the clamp along the longitudinal axis thereof, the handle being positioned for rotation about the longitudinal axis and constrained against reciprocation along the longitudinal axis. Also, a dust cover for the recesses of the tool post is disclosed.
