Abstract
A self-actuating keyless chuck for use with a reversible powered driver is disclosed. The chuck comprises a body which carries a rotatable split nut and a plurality of slidable jaws driven by the rotatable nut. A sleeve member is rotatably connected to the body and carries an impact ring provided with a first impact dog. A second impact dog is associated with the split nut. Spring means are provided to bias the first impact dog toward engagement with the second impact dog whereby the jaws will be tightened or loosened whenever the rotation of the sleeve is restrained and the powered driver is actuated.
