ABSTRACT:
A ratchet wrench in which the mechanism determining the operative mode is remotely controlled from the grip, or handle end of the wrench. A rod, supported for reciprocating translation along the shank of the wrench, is pivotally interconnected to a radial portion of the reverse control knob of a conventional ratchet. The rod extends to the handle end of the wrench, where it is terminated by a tab, readily manipulated by the thumb of the user. Through appropriate fore and aft movement of the convenient tab, one-handed control of the rotation and operative action of the wrench is afforded.
