Abstract: A systen for extending and retracting the waste hose for a waste disposal system that is typically found on recreational vehicles and includes power or crank-driven hose extender means for extending the collapsible hose from its collapsed mode stored on-board the recreational vehicle, to its extended configuration which it is used for dumping waste from an RV holding tank into an inlet of an RV waste dump station. The system includes a specialized hose extension and retraction mechanism, and a universal coupling at the end of the hose which will fit waste station inlet pipes of all the commonly used sizes, which run from 3" to 41/2" in diameter. In addition, a special structure is used to create a 90 degree bend in the outboard end of the hose, and an optional unidirectional cuff around the hose will hold tension on the hose so it can be stretched between the recreational vehicle and the inlet, but will permit the hose to be manually pushed back through the cuff without substantial resistance.

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.
