ABSTRACT:
A remote control apparatus for varying engine speeds includes a housing and a reversible constant-speed electric motor mounted on the housing, the motor being adapted to drive a pulley at a substantially lower rotational speed through speed reducing gears disposed in the housing. A pair of stops are adjustably mounted on opposite sides of the pulley for stopping the motor upon contact with a pendulum member after a predetermined rotation of the pulley in either direction. A chain attached at one end to the pulley is attachable at its other end to a spring-biased throttle rod of an engine or the like, the chain being wound around the pulley upon rotation of the motor to exert a pull upon the throttle rod and increase the speed of the engine. Rotation of the pulley sufficiently to cause a stop to actuate the pendulum member causes the motor to stop, thereby maintaining the engine speed at a predetermined maximum. Reversing of the motor permits similar controlled deceleration of the engine to a predetermined minimum speed.
