ABSTRACT:
An eccentric pulley arrangement either driven or driving by which rotary motion can be transferred to reciprocal motion. A pulley has an angled shaft through its center of rotation with a second shaft through the angled shaft. Movement of the angled shaft with respect to the pulley or the second shaft changes the center of rotation of the pulley and hence the degree or eccentricity can be changed during motion.
