ABSTRACT:
Oscillatory motion of a first end of a lever arm is converted to incremental rotational motion of an output shaft connected to a second end of the lever arm. The second end oscillates with an amplitude determined by a fulcrum adjustable along the lever arm. The output shaft is coupled to the second end of the lever arm by a wrapped spring arrangement.
