ABSTRACT:
A ratchet drive screw-driver includes a handle, a rotor journaled in one end of the handle with a screw-driver shank extending axially therefrom, a ratchet wheel and pawl mechanism for rotating the rotor, and an actuator mechanism for driving the ratchet. The actuator mechanism includes an elongated push rod positioned longitudinally in the handle and extending out the end of the handle perpendicular to the axis of rotation of the rotor. Reciprocating longitudinal motion of the push rod drives the ratchet mechanism and turns the rotor in either forward or reverse angular direction as desired. The ratchet mechanism can also be driven by swinging the handle about the axis of the rotor if desired.
