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'.
Hermle Clocks (1922–present) Junghans, Schramberg (1861–present) Kieninger Clock Company, initially in Mönchweiler, 1921 new factory in Aldingen (1912–present) Kieninger & Obergfell Uhrenfabrik (KUNDO trademark), Sankt Georgen (1918 - recent) Kienzle Uhren, Schwenningen - Schlenker and Keinzle until c1897 (1883-1996) Franz Ketterer
Anchor escapement clocks driven by a mainspring required a fusee to even out the force of the mainspring. It is a recoil escapement as mentioned above; the momentum of the pendulum pushes the escape wheel backward during part of the cycle. This causes extra wear to the movement, and applies varying force to the pendulum, causing inaccuracy.
Tourbillon. In horology, a tourbillon (/ tʊərˈbɪljən /; French: [tuʁbijɔ̃] "whirlwind") is an addition to the mechanics of a watch escapement to increase accuracy. Conceived by the British watchmaker and inventor John Arnold, it was developed by his friend the Swiss-French watchmaker Abraham-Louis Breguet and patented by Breguet on 26 ...
The importance of the escapement in the history of technology is that it was the key invention that made the all-mechanical clock possible. [1] [2] The invention of the first all-mechanical escapement, the verge escapement, in 13th-century Europe initiated a change in timekeeping methods from continuous processes, such as the flow of water in water clocks, to repetitive oscillatory processes ...
