Breaker bar with 90 degree rotating socket connector head

A wrench for driving sockets in the form of a breaker bar having a ninety degree torque rotation head, comprising in combination:

• a) an elongate handle;
• b) a head portion including a cylindrical cavity having a first axis perpendicular to the handle
• (c) an intermediate cylindrical portion disposed between the handle and head and fixed to the head, and including a central longitudinal throughbore having a second axis parallel to the handle;
• c) a central spindle fixed to the handle and journalled for rotation within the longitudinal throughbore;
• d) a driving member including a flat face, a body portion and a neck portion, the neck portion being fixed to an end of the central spindle such that the driving member rotates therewith;
• e) a driven member fixed to a rotatable post the post being disposed parallel to the first axis, the post including a cylindrical portion and a rectangular solid portion for selectively receiving a socket wrench head, the driven member engaging the driving member such that rotation of the central spindle is translated to the post;
• f) a generally cylindrical bearing block disposed within the cylindrical cavity, having a cylindrical portion with a top face providing a bearing surface for the driven member, the bearing block also including a flat face in bearing contact with the flat face of the driving member to provide a bearing surface for the driving member, the bearing block also including a central bore for receiving and journalling the cylindrical portion of the post, the cylindrical cavity including bearing surfaces in bearing contact with the body portion and the neck portion of the driving member, the driven member comprising a driven plate including a radial center, the driven plate having drive balls of a given diameter fixed thereto and recessed therein, the drive balls being radially spaced from the radial center and circumferentially spaced about the driven plate.
