Title: Shaft drive alternately for both directions of rotation

Abstract: A shaft drive alternately for both directions of rotation, comprises, a shaft rotatably supported on bearings having first and second turbines connectable thereto, each including a respective first and second turbine wheel freely rotatable on the shaft in respective opposite first and second directions. The turbine wheels are driven by fluid which rotates the wheels in a selected direction and, in addition, displaces the turbine wheels so that a friction disc carried thereby is engaged with a respective first and second clutch to connect it to the shaft to impart the selected direction of rotation. When the turbine is stopped by not directing the fluid into the blades, in which case the clutch mechanism is moved out of engagement and the turbine wheel may run free of the shaft, the second turbine wheel may be connected in a similar manner by effecting engagement of the associated second clutch with the shaft when the fluid is directed to the second turbine for rotating the turbine wheel.
