Abstract
A rotary power driver is provided which drives with a two-stage torque and speed control, wherein the initial driving is done at higher speed and lower torque, and a subsequent higher torque is automatically imposed with lower speed. The second stage is a selected pre-set stage, with provision for the selected torque built into the driver. The second stage is imposed on the drive shaft by a one-way clutch or ratchet drive.
