Two-speed fastener driver
First Claim
1. In a fastener driving tool including a reversible rotary motor including a reversal means upon demand and having an output shaft connected in axial alignment with a tool driving output shaft by improved drive means, said improved drive means comprising a first overrunning clutch means axially aligned with the motor output shaft for providing a high speed drive connection with the tool driving output shaft when the motor is rotated in a first direction, and a second overrunning clutch means surrounding said first overrunning clutch means for providing a low speed drive connection with the tool driving output shaft when the motor is rotated in a direction opposite to the first direction.

Abstract
A two-speed fastener driving tool includes a reversible rotary motor including means to reverse, having an output shaft connected in axial alignment with a tool driving output shaft by an improved drive assembly comprising a first overrunning clutch axially aligned with the motor output shaft for providing a high speed drive connection with the tool driving output shaft when the motor is rotated in a first direction. A second overrunning clutch surrounds the first overrunning clutch and functions for providing a low speed drive connection with the tool driving output shaft when the motor is rotated in a direction opposite to the first direction.
