ABSTRACT:
A chuck for lathes and other machine tools has a chuck body provided with axially shiftable wedging members to actuate the jaws, a rotatable guard ring prevents full axial withdrawal of these members from sockets in the jaws in one angular position of the ring. In another angular position of the ring recesses in the latter are aligned with the wedging members to allow the latter to clear the jaws for radial withdrawal and replacement thereof.
