Abstract

7459. Duff, E. J. March 28. Driving-gear for screw propellers. - The engine drives a propeller shaft passing through a tunnel in the ship, and its rotative effect is augmented by utilizing the power which is in the head of water required to float the ship. Upon the same shaft as the prime-mover A is fitted a turbine E, or equivalent motor, driven by the head of water above the inlet D. Propellers F eject the tail waters and thereby give the forward propulsive thrust. Instead of the propeller F, a rotary pump G may be used. This arrangement may be duplicated with twin screws. In a modification, two screw propellers on separate shafts are driven by separate engines and turbines, the turbines discharging into a common tunnel provided with a rotary pump driven by a prime-mover.
