dead-beat escapement

The dead-beat escapement is a type of escapement mechanism used in clocks and watches. Its primary function is to control the release of energy from the power source to the timekeeping component, allowing for precise measurement of time.

Invented around 1675–76, the dead-beat escapement was an improvement over earlier designs like the verge escapement. It works by allowing the escape wheel to come to a complete stop, or "dead beat," between impulses. This design minimizes the impulse given to the pendulum or balance wheel, reducing interference and allowing the oscillator to swing more freely. This innovation significantly improved the accuracy of timekeeping devices. Thomas Tompion, a renowned English clockmaker, was among the first to use early forms of the dead-beat escapement in clocks.12
