Description:
Reuleaux refers to these as power escapements. He made analogy to these rigid link ratchet escapements and the fluid controlled valve gears in steam engines. These devices fall into the category of control or regulator mechanisms, after the first machine controller of James Watt. He even draws a closed loop block diagram in page 231 of The Constructor, for a control mechanism. However he always thought of these regulators as kinematic devices determined by geometry and not as dynamic devices dependent on Newton's laws of motion.
