ABSTRACT:
A ratchet wrench having a handle and an integral head. The head has a chamber formed therein with a wall about the chamber. At least one tooth is formed on the wall and projects into the chamber. A cylindrical rotor having a plurality of axial teeth is disposed in the chamber. The chamber is non circular and has a cross-sectional area greater than the cross-sectional area of the rotor wherein the rotor is translatably and eccentrically movable within the chamber. Movement of the handle engages a portion of the teeth on the rotor in locked driving engagement with the wall of the chamber and the at least one tooth on the wall of the chamber. Backswinging the handle disengages the rotor. Three embodiments are disclosed. Methods of use of the three embodiments are disclosed.
