Classification: CPC B | IPC B

Claim 0:
1. A tool adapted to apply torque to a work piece, the tool comprising:
a handle;
a head extending from the handle, the head including first and second bores perpendicular to the head, the first and second bores respectively having first and second radial openings;
a drive gear disposed within the head and adapted to apply torque to the work piece;
first and second pawls adapted to engage the drive gear;
a reversing lever adapted to selectively allow either one of the first and second pawls to engage the drive gear; and
first and second bias members respectively disposed within the first and second bores, the first and second bias members respectively radially extend partially out of the first and second radial openings and respectively towards the first and second pawls, wherein the first and second radial openings are smaller than the first and second bias members to restrict the first and second bias members from respectively moving completely radially out of the first and second bores,
wherein when the first pawl engages the drive gear, the second pawl is disengaged from the second bias member, and the first bias member is radially compressed by the first pawl and biases the first pawl into engagement with the drive gear, and
when the second pawl engages the drive gear, the first pawl is disengaged from the first bias member, and the second bias member is radially compressed by the second pawl and biases the second pawl into engagement with the drive gear.
