ABSTRACT:
A flat support member mounted on and extending above a horizontal worktable has an elongated, inclined slot therein with a rack formed along its upper side, a wheel lying along one side of the member and rolling on a workpiece on the table has a coaxial pinion gear of smaller diameter than the slot width fixed to one face thereof and loosely retained in the slot, horizontal movement of the workpiece in one direction moves the pinion horizontally out of engagement with the rack and causes rotation of wheel and pinion in one direction and movement of the workpiece in a reverse direction moves the pinion horizontally into engagement with the rack and causes rotation of the wheel and pinion in an opposite direction to apply downward pressure of the wheel on the workpiece.
