Abstract
A jaw chuck construction having an inner sleevelike body containing a plurality of radial guide grooves in which are slidably disposed jaw carriers. An actuator device is axially slidably supported within the inner body and has axially projecting wedges which cooperate with mating wedges formed on the jaw carriers for camming same radially toward or away from a workpiece. The axially projecting wedges slidably project into central slots formed in the individual jaw carriers for engaging the latter substantially centrally of the jaw carrier to minimize tilting and off-center loading of the jaw carriers. The inner body and the jaw carriers are confined by an outer sleevelike body which snugly embraces the inner body and slidably engages the outer radial surfaces of the axially projecting wedges, whereby centrifugal forces imposed on the jaw carriers are transmitted directly to the axially projecting wedges and then imposed directly on the surrounding outer body so that the centrifugal forces do not appreciably affect or reduce the gripping force between the jaws and the workpiece.
