Abstract
A chuck for use with a manual or powered driver having a drive shaft is provided. A generally cylindrical body has a forward section and a rearward section, the rearward section adapted to mate with the drive shaft of the driver. A gripping mechanism is actuatable to a closed position in which the gripping mechanism axially and rotationally retains a tool with respect to the body and to an open position in which the gripping mechanism does not so retain a tool. An annular nut is disposed about the body and has a threaded portion in threaded engagement with the gripping mechanism so that rotation of the nut about the body in a closing direction actuates the gripping mechanism to the closed position and rotation of the nut in an opening direction, opposite the closing direction, actuates the gripping mechanism to an open position. One of the nut and the gripping mechanism includes a rotational stop which, when the gripping mechanism reaches a predetermined position while being actuated by rotation of the nut in the opening direction, abuts the other of the nut and the gripping mechanism in a rotational direction with respect to the axis of the body to oppose further rotation of the n…
