Abstract
A mechanical quill and spindle drive mechanism is disclosed wherein the quill is advanced by means of a screw formed about its periphery and cooperating with a driven ball nut. The quill is received within a housing bore and accurately guided for longitudinal movement thereby by means of a sliding engagement with bore surfaces on either side of the nut. The spindle is carried by the quill throughout its longitudinal movement and is rotated by means of a splined drive shaft which maintains a rotative connection therewith by means of a splined connection therebetween.
