ABSTRACT:
A male slide member, which is mounted to reciprocate in a rectangular recess formed in the face of a base member, is supported at one side thereof by a plurality of ball bearings for substantially friction-free movement with respect to one side of the recess, and is supported at its opposite side by an elongate bearing rod carried by the male slide member to have frictional, sliding movement with respect to a pair of spaced, parallel bearing surfaces that extend longitudinally of the other side of the recess in the base member. The bearing rod has formed in its periphery longitudinally spaced gear teeth which mesh with the teeth of a pinion gear mounted on the base member to rotate adjacent the bearing rod, and selectively to drive the rod and its attached slide member in opposite directions.
