The invention of the verge and foliot escapement in c.1275 [87] was one of the most important inventions in both the history of the clock [88] and the history of technology. [89] It was the first type of regulator in horology. [6] A verge, or vertical shaft, is forced to rotate by a weight-driven crown wheel, but is stopped from rotating freely ...
Similar methods of measuring time were used in medieval churches. [citation needed] The invention of the candle clock was attributed by the Anglo-Saxons to Alfred the Great, king of Wessex. The story of how the clock was created was narrated by Asser, who lived at Alfred's court and became his close associate. [2]
As the clock's gears turn the crown wheel (see animation), one of its teeth catches on a pallet, pushing on it. [13] This rotates the verge and foliot in one direction, and rotates the second pallet into the path of the teeth on the opposite side of the wheel, until the tooth slides off the end of the pallet, releasing it.

From its invention in 1656 by Christiaan Huygens, inspired by Galileo Galilei, until the 1930s, the pendulum clock was the world's most precise timekeeper, accounting for its widespread use. [ 1 ] [ 2 ] Throughout the 18th and 19th centuries, pendulum clocks in homes, factories, offices, and railroad stations served as primary time standards ...
