Abstract
A chuck for use with a manual or powered driver having a rotatable drive shaft includes a pawl having a deflectable burr biased toward a catch in a chuck driver. A chuck sleeve defines a cam surface disposed with respect to the catch and the burr so that the cam surface disengages the burr from the catch when the sleeve is in a first position with respect to the driver and releases the burr to engage the catch, and rotationally fix the pawl to the driver, when the sleeve is in a second position with respect to the driver. The pawl is rotationally fixed to the chuck body when the sleeve is in the second position.
