ABSTRACT:
The described motion converter has a housing in which a drive shaft is interconnected with a rotary motion power source. The drive shaft has an extent having a left-hand thread adjacent one end thereof and an extent having a right-hand thread located adjacent the opposite end thereof. Threaded nuts on the left and right hand threaded portions each have spiral spring clutches. An actuator is slidingly received upon the intermediate portion of the drive shaft with pins located at opposite ends of the actuator to engage one spring clutch while releasing the other. A spring loaded positioning device associated with the actuator insures that the actuator is positively located to engage one or the other of the clutches and prevents the actuator from hanging up at an intermediate position.
