ABSTRACT:
A chuck for use with a manual or powered driver having a rotatable drive shaft including a primary tightening mechanism utilizing a three-jaw assembly actuated by a nut or tightening ring and a supplemental tightening mechanism. The supplemental tightening mechanism includes a camming portion defining a tightening cam profile. The supplemental tightening mechanism further includes a plurality of lever bars, one end of each of the lever bars forming a cam follower and the other end of each of the lever bars operatively associated with the nut so that when the supplemental tightening mechanism is actuated in a tightening direction, the lever bars will force the nut forward to produce an enhanced tightening force on the tool through the jaws. The supplemental tightening mechanism is configured to allow drive through release.
