Governor

The Musician, detail of movement

A device for slowing and regulating motion.

In striking clocks and watches, the fly wheel has vanes which regulate the speed of the striking train. The same result is achieved by a centrifugal governor or by the escapement: a lever escapement for certain striking mechanisms (invented by Julien Le Roy in 1755); a verge escapement for alarms.
