ABSTRACT:
A jointed drive unit is provided having a power output shaft used for driving a socket or the like, and an input shaft which transmits power to the output shaft through a gearbox permitting any angular orientation between input and output shafts greater than about 20.degree.. The mechanism is more than merely a gearbox for transmitting rotational motion at an acute angle because due to the gear arrangement and a ratchet mechanism incorporated in the preferred embodiment the output shaft can be made to rotate, not only by rotating the input shaft, but also by pumping the input shaft in a plane parallel to the output shaft, or alternatively, moving the input shaft back and forth in a plane perpendicular to the output shaft in conventional open end or box end ratchet wrench fashion.
