  2. Verge escapement - Wikipedia

    en.wikipedia.org/wiki/Verge_escapement

    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'. Verge escapements were used from the late 13th century until the mid 19th century in clocks and pocketwatches.

    The Backhaus Clock, also known as the Forchtenberg Tower Clock, is a historical mechanical tower clock located in Forchtenberg, Baden-Württemberg, Germany. It is notable for the year 1463 engraved on its frame in Gothic script , which marks it as the oldest dated tower clock still in operation in the world. [ 1 ]

    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 ...

    Keys of various sizes for winding up mainsprings on clocks Mechanism of a Wall Clock, Ansonia Co. 1904. The stored amounts of energy used by a given piece during its operation is often housed within it; this frequently happens via a winding device that applies mechanical stress to an energy-storage mechanism such as a mainspring, thus involving some form of escapement.

    en.wikipedia.org/wiki/Clock

    The verge escapement mechanism appeared during the surge of true mechanical clock development, which did not need any kind of fluid power, like water or mercury, to work. These mechanical clocks were intended for two main purposes: for signalling and notification (e.g., the timing of services and public events) and for modeling the solar system.
