Abstract
An axially movable sleeve has interference members or lugs engageable with interference members or lugs associated with the split nut in a chuck. When the chuck is driven by the spindle, the axially movable interference members engage the split nut interference members and are restrained from rotation. The nut is also restrained and the chuck jaws open or close depending upon the direction of rotation of the chuck body. The sleeve is positioned to be engaged by the jaws as they approach full open position. The jaws then move the sleeve axially to disengage the interference members and stop further opening of the jaws before they reach a position to wedge or jam in the open position.
