ABSTRACT:
A power receiving, torque translating, output device receives reciprocating power from a plurality of external power producers. The received reciprocating power is timed and controlled by a cam affixed inside a rotor rotating about a stationary central shaft. The central shaft is mounted inside an octagonal central block, and extends to provide rotatable mounting for the rotor. The rotor has a drum shaped portion so positioned as to overlap the entire length of the block thus placing the cam in close proximity rotation around the block. The block has rectangular grooves adapted to guide a plurality of cam following actuators during the reciprocating motion of each one. Each actuator derives motion from a connecting rod attached both to the actuator and to its respective external power producer. Each cycle of reciprocation of each actuator contains one power stroke in each direction for a total of two power strokes per cycle. Each actuator has a cam follower beading adapted to cause interaction between the rectangular grooves and the rotating cam. The cam has a two cycle sinusoidal profile which times the followers to two cycles of reciprocation for each revolution of the cam. Therefor, two cycles of reciprocation by the actuators will cause one revolution of the rotor which is taken as output from the outer surface of the rotor either by belts or chain or by inclusion in other external devices such as a propeller or wheel hub.
