    Abstract: A socket wrench for turning sockets has a handle joined to a head having an inside wall accommodating a body including a socket holder. A permanent magnet attached to the socket holder holds a socket on the socket holder. The body has a plurality of ramps facing the inside wall of the head. Rollers engage the ramps and inside wall. A member mounted on the body engages the rollers to selectively shift the rollers relative to opposite end sections of the ramps. First and second permanent magnets on the body and member maintain the member in selected shifted positions to retain the rollers adjacent the end sections of the ramps.

    Abstract: An air motor socket wrench has an air motor secured to a housing of a socket drive assembly having a socket drive member provided with a socket lock ball movable between a socket lock position and a socket unlock position. A hexagon body has inwardly inclined ramp sections adjacent an inside continuous cylindrical wall of a yoke drivably connected to the motor to oscillate the yoke. Rollers located between the ramp sections and cylindrical wall of the yoke transmits rotational movement of the yoke to the body and socket drive member. A muffler mounted on the air motor reduces the noise generated by the air motor.
