Abstract:
1. A high speed device for attachment to a ratchet type socket wrench to accommodate high speed operation of the wrench, comprising: a high speed drive pulley adapted to be removably attached to a drive portion of the socket wrench and to receive an alternate drive source, the high speed drive pulley having a cylindrical outer wall with a drive force receiving structure on an outer surface of the cylindrical outer wall, the pulley further having a connecting portion coupled to the outer wall and situated in a plane substantially perpendicular to the axis of the cylindrical outer wall, the connecting portion having a coupling structure capable of being selectively attached to the drive portion of the ratchet type socket wrench; a cover rotatably attached to the pulley and surrounding a portion of the drive force receiving structure, the cover configured to create a predetermined space between the cylindrical outer wall and an inner surface of the cover; and a drive belt positioned within the predetermined space, the drive belt having a force transfer structure engaged with the drive force receiving structure, whereby pulling on the belt will cause rotation of the high speed drive pulley.
