ABSTRACT:
A chuck has a spring connection between the nut which rotates to advance or retract the jaws and the control ring or sleeve which the user rotates to operate the chuck. The spring normally transmits tightening or loosening rotation from the sleeve to the nut. When the jaws contact a tool, however, the spring allows the sleeve to continue to rotate even though the nut is stopped by the jaw-tool contact. Continued rotation of the sleeve relative to the nut causes a cam mechanism interposed between these two elements to force the non-rotating nut axially forward. This applies a final tool-gripping force to the jaws.
