ABSTRACT:
A jaw chuck for mounting on a spindle in which a chuck body is provided which has chuck jaws radially reciprocable thereon. A piston is reciprocable on the chuck axis and cooperating elements of cam means are provided on the piston and the jaws for positively moving the jaws on the chuck body. A fluid piston is connected by a draw bar to the jaw actuating piston for actuation thereof. The pistons are normally movable within that range in which the cam elements are engaged but can be moved to a position where the cam elements are disengaged to permit the jaw elements to be removed from the chuck body. Detent and safety means are provided for preventing the jaws from coming out of the chuck body except when deliberately removed therefrom.
