Abstract
Transmission system for forming cyclical motion from rotational motion including a device having a rotating part and at least one control lever set into cyclical motion by rotational motion of the rotating part, the one control lever and the rotating part being in cooperative engagement whereby a varying force is applied to the control lever producing a torque fluctuation in the rotational motion, includes another device for producing cyclical motion, the other device being in operative engagement with the rotating part, and spring means for applying a force to the rotating part so as to compensate for the torque fluctuation.
