ABSTRACT:
A device for generating a unidirectional force comprises a rotary body carrying around its periphery a plurality of pivotal pendulum masses mounted on shafts parallel to the axis of rotation of the rotary body. As the body rotates the masses are moved inwardly to a retracted position by a cam surface and then are free to swing outwardly at an abrupt end of the cam surface. Each pendulum mass is associated with a leaf spring which rotates with the rotatable body and carries a roller on an outer end thereof for engaging a side of the pendulum mass so as to bias the pendulum mass back to the retracted position. The spring thus acts to control the flinging movement of the pendulums as they move outwardly and to gradually return them to the retracted position for reengagement with the cam surface.
