Subject: Drum Clutch

I have a 25-1 reduction gearbox rated at 25 hp which I want to convert
to a logging winch. The output shaft is 10 inches long-the first 4" is 
3" in dia. and the remaining 6" is 2" in dia. Does anyone know of a
simple clutch design or an industrial application that I can use with a 
drum mounted on this shaft that would be free-turning to pull out the
cable and would turn the drum when power is applied to the input shaft.
Any help would be appreciated.

Automatic 4WD front hubs might do it. The wheel turns freely either way
while the axle is stationary. Once the axle starts turning, it forces a
cam into engagement with the wheel. Maybe you can salvage one.
