Abstract
A differential rotary-to-rotary cam system to achieve long dwell periods with continuous rotary input including a rotary prime mover of several different types and a differential cam assembly which can be interposed between a particular power input and a power output to produce a repetitive differential motion wherein a long dwell is obtained at the rotary output. This is particularly enhanced when the differential is driven by a basic power system which in itself can produce a dwell in its output motion.
