ABSTRACT:
A multi-mode wrench comprised of a drive head and a housing in which a drive system is positioned together with an axially and rotatably movable handle for selecting among various operating modes offered by that drive system. The wrench, accordingly, provides for a wide variety of bolt or nut tightening or loosening operations, making such work in especially tight or confined areas easier where it might not otherwise be possible to move wrenches in a normal oscillating fashion to apply torque to adequately tighten or loosen a connection. The wrench has five operating modes which vary from a fully, inner locked condition, where the housing, the drive system and the handle are all locked together so the wrench can operate like a box wrench, a neutral position where the drive system can idle within the housing and handle allowing for drive by various sorts of external mechanical or air driven drive means, two main drive positions where the handle can ratchet alternately in either clockwise or counterclockwise direction and an outer locked condition where the handle is locked directly to the drive system.
