Abstract
Power take-off gearing for separate drives, for the propellers of an amphibious vehicle, or the like: A main drive shaft drives two separate driven shafts through respective slip clutches. Each clutch comprises a set of interleaved disks. A respective plunger selectively presses or does not press each set of disks together to drive each driven shaft at a speed dependent upon the plunger pressure. Hydraulic means which are solenoid valve controlled selectively activate and deactivate the clutch plungers, each clutch has its own control valve. A brake for both driven shafts is also activated by the solenoid valve.
