Abstract
Wedge chuck having grooves in the sides of each jaw and in the adjacent sides of its way in the chuck body, of which the grooves in all jaws form a given angle with a common plane normal to the chuck axis in which all jaws move, and the grooves in each way lie in a plane normal to the common plane and to the median plane of the associated way in which the chuck axis lies, and a jaw actuator guided in the chuck body for movement in the direction of the chuck axis and carrying sets of follower keys of which the keys of each set are received with a sliding fit in the grooves in a jaw and in the grooves in the associated way, whereby on back and forth movement of the actuator the grooves and follower keys cooperate to move the jaws to and from the chuck axis.
