    en.wikipedia.org/wiki/Maintaining_power

    Huygens' maintaining power in use. The weight drive used by Christiaan Huygens in his early clocks acts as a maintaining power. In this layout, the weight which drives the clock is carried on a pulley and the cord (or chain) supporting the weight is wrapped around the main driving wheel on one side and the rewinding wheel on the other.

  3. Riefler escapement - Wikipedia

    en.wikipedia.org/wiki/Riefler_escapement

    It was used in the astronomical regulator clocks made by his German firm Clemens Riefler from 1890 to 1965, [3] which were perhaps the most accurate all-mechanical pendulum clocks made. An escapement is the mechanism in a mechanical clock that gives the pendulum precise impulses to keep it swinging, and allows the gear train to advance a set ...

    en.wikipedia.org/wiki/Remontoire

    Before the common use of electronic clocks in automobiles, automobile clocks had mechanical movements, powered by an electric remontoire. A low power drive spring would be wound every few minutes by a plunger in a solenoid, powered by the vehicle's service battery and activated by a switch when the spring tension got too low. Such clocks were ...

  5. Wheel train - Wikipedia

    en.wikipedia.org/wiki/Wheel_train

    In striking clocks, the striking train is a gear train that moves a hammer to strike the hours on a gong. It is usually driven by a separate but identical power source to the going train. In antique clocks, to save costs, it was often identical to the going train, and mounted parallel to it on the left side when facing the front of the clock. [11]

    The tower clock of Norwich Cathedral constructed c. 1273 (reference to a payment for a mechanical clock dated to this year) is the earliest such large clock known. The clock has not survived. [ 95 ] The first clock known to strike regularly on the hour, a clock with a verge and foliot mechanism, is recorded in Milan in 1336. [ 96 ]

  7. Escapement - Wikipedia

    en.wikipedia.org/wiki/Escapement

    The sudden stopping of the escapement's tooth is what generates the characteristic "ticking" sound heard in operating mechanical clocks and watches. The first mechanical escapement, the verge escapement , was invented in medieval Europe during the 13th century and was the crucial innovation that led to the development of the mechanical clock.

  9. Balance wheel - Wikipedia

    en.wikipedia.org/wiki/Balance_wheel

    As clocks were made smaller, first as bracket clocks and lantern clocks and then as the first large watches after 1500, balance wheels began to be used in place of foliots. [8] Since more of its weight is located on the rim away from the axis, a balance wheel could have a larger moment of inertia than a foliot of the same size, and keep better ...
