Abstract

See full text

An improved socket wrench (300) is provided which includes a first pawl (318) sliding on a first slide surface (312) and a second pawl (320) sliding on a second slide surface (314). At least one of the slide surfaces is not perpendicular to a radial line from the axis of rotation (27') of the drive member (302) intersecting the plane of the slide surface when the slide surface is least distant from the rotational axis. This provides an increase in the number of pawl engagements per revolution over that possible with only a single pawl. A square drive to hex drive adapter (380) and a hex drive to square drive adapter (400). Finally, retainer spring (414) is used to frictionally engage sockets on a breaker bar (260).
