Abstract: A locking clutch ratchet wrench (1) is configured such that a clutch ring (500) forms the mid part of aminate like structure. Under torque applying conditions, the compression forces applied to the clutch ring (500) are substantially dissipated around the circumference (507) of the clutch ring. This inwardly directed force clamp against the inherently strong outer surface 405 of the drive element (400). The resultant pseudo laminate structure of the drive element (400), clutch (500) and housing (201, 202) enables the construction of a proportionately stronger ratchet wrench of reduced height or width.

Abstract: The mechanical technology of converting oscillatory motion, into one direction of rotation, as described and claimed in U.S. Pat. No. 5,881,609, while being efficient, useful and having numerous applications, has its disadvantage of not being able to function unless user employs both hands; one hand to apply oscillatory motion to an input, while opposite hand immobilizes the axial rotation of the converting gear-train, in order for the conversion to be activated. Hence, the goal of this documentation, is to teach several different means, that maintain the immobility of axial rotation of the dual-drive gear train in order to activate the dual-drive feature, without the use of either of user's hands, thereby conveniently leaving one of user's hands available for holding a work piece.
