  2. Grandfather clock - Wikipedia

    en.wikipedia.org/wiki/Grandfather_clock

    A grandfather clock (also a longcase clock, tall-case clock, grandfather's clock, hall clock or floor clock) is a tall, freestanding, weight-driven pendulum clock, with the pendulum held inside the tower or waist of the case. Clocks of this style are commonly 1.8–2.4 metres (6–8 feet) tall with an enclosed pendulum and weights, suspended by ...

  3. Anchor escapement - Wikipedia

    en.wikipedia.org/wiki/Anchor_escapement

    Anchor escapement. The anchor and escape wheel of a late 19th-century clock. The plate that normally holds the front end of the pinions has been removed for clarity. The pendulum is behind the back plate. In horology, the anchor escapement is a type of escapement used in pendulum clocks. The escapement is a mechanism in a mechanical clock that ...

  4. Striking clock - Wikipedia

    en.wikipedia.org/wiki/Striking_clock

    All hour striking mechanisms have these parts. [14] The letters below refer to the diagram. Power source – This is usually identical to the device that powers the clock's timekeeping mechanism: in weight driven clocks it is a second weight on a cord (P), in spring driven clocks it is another mainspring. Although older one-day (30-hour) clocks ...

  5. Escapement - Wikipedia

    en.wikipedia.org/wiki/Escapement

    Escapement. Animation of anchor escapement, widely used in pendulum clocks. An escapement is a mechanical linkage in mechanical watches and clocks that gives impulses to the timekeeping element and periodically releases the gear train to move forward, advancing the clock's hands. The impulse action transfers energy to the clock's timekeeping ...

  6. Verge escapement - Wikipedia

    en.wikipedia.org/wiki/Verge_escapement

    Verge and foliot escapement from De Vick tower clock, built in Paris, 1379, by Henri de Vick. The verge (or crown wheel) escapement is the earliest known type of mechanical escapement, the mechanism in a mechanical clock that controls its rate by allowing the gear train to advance at regular intervals or 'ticks'.

  7. Clockwork - Wikipedia

    en.wikipedia.org/wiki/Clockwork

    Clockwork. Clockwork refers to the inner workings of either mechanical devices called clocks and watches (where it is also called the movement) or other mechanisms that work similarly, using a series of gears driven by a spring or weight. [1][2][3] A clockwork mechanism is often powered by a clockwork motor [4] consisting of a mainspring, a ...

  8. Galileo's escapement - Wikipedia

    en.wikipedia.org/wiki/Galileo's_escapement

    Galileo's escapement is a design for a clock escapement, invented around 1637 by Italian scientist Galileo Galilei (1564–1642). Galileo was one of the leading minds of the Scientific Revolution. [1] He was dubbed the founder of theoretical physics. [2] He is also credited with the invention of the celatone (a type of telescope) and the ...

  9. Maintaining power - Wikipedia

    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.
