Abstract
Abstract A RATCHET WRENCH FOR HIGH SPEED, LOW TORQUE AND LOW SPEED, HIGH TORQUE OPERATION HAS A REEL INSIDE A CASING ROTATABLE ON AN AXIAL SHAFT. A FIRST PAWL CARRIED BY THE REEL ENGAGES A RATCHET WHEEL SECURED TO THE SHAFT TO TURN THE SAME WHEN THE REEL TURNS. A SECOND PAWL CARRIED BY THE COVER PLATE ENGAGES THE RATCHET WHEEL TO TURN THE SHAFT WHEN THE CASING IS TURNED BY RADIALLY-EXTENDING HANDLES. A CABLE WOUND ON THE REEL MOVES AXIALLY OF THE HANDLE FOR FAST TURNING THE REEL WHEN A REMOVABLE EXTENSION IS PULLED FROM ONE OF THE HANDLES.
