Geneva mechanism

== English == === Etymology === So called from Geneva in Switzerland, an important center of watchmaking. === Noun === Geneva mechanism (plural Geneva mechanisms) (mechanics) A mechanism that translates a continuous rotation into an intermittent rotary motion, using an intermittent gear where the drive wheel has a pin that reaches into a slot of the driven wheel and thereby advances it by one step, and having a raised circular blocking disc that locks the driven wheel in position between steps. === Further reading === Geneva mechanism on Wikipedia.Wikipedia
