ABSTRACT:
Each of the jaws of a sliding jaw chuck are moved between workpiece clamping and release positions by a post, the end of which, in active position, is seated in an opening in an octogonal plate seated in a recess in the jaw. The plate is octagonal and its dimensions are such that it always entirely occupies the recess in the direction of movement of the jaw. In contrast, the recess is wider than the plate, permitting the plate, after removal from the recess, to be rotated about the post to any one of five positions. While the plate is symmetrical about its geometric center, the opening for the post is offset from the plates's center which results in changes in the spacing between the post and the ends of the recess, which controls the radial position of the jaw with respect to the axis of rotation of the chuck and thus the size of the workpiece which it can clamp.
