Abstract
A drive train for a pulsed feed wheel has an offset cam on a continuously rotating drive shaft. The cam acts against a pendulum which rocks the input of a one-way clutch. A support arm attached to the output of the clutch terminates in a planetary gear. The planetary gear meshes with two sun gears one of which is fixed against rotation and the other of which is keyed to the output shaft. The planetary gear and sun gears are harmonic gears. Each revolution of the drive shaft pulses the output shaft through a small fraction of one revolution.
