ABSTRACT:
An operator for a Jacobs chuck has an annular support pivoted on the chuck collar for rocking movement about an axis perpendicular to the chuck axis, a gear tooth on the support between the pivot axis and the chuck ring gear which is selectively engageable with the ring gear teeth so that rocking the support causes the gear tooth to rotate the ring gear, and means permitting manual movement of the gear tooth into and out of engagement with the ring gear teeth. The annular support is counterbalanced so its center of mass is on the chuck axis, and a stabilizer normally maintains the support in a plane perpendicular to said axis.
