====== Lever escapement ======
A **lever escapement** is an [[escapement]] by means of a stone [[anchor]] with pallets. This principle has been invented around [[1715]] by the English watchmaker [[Graham, George|George Graham]]. A further development of the so-called **free anchor escapement**, also called [[Swiss lever escapement]], was invented in [[1765]] by [[Mudge, Thomas|Thomas Mudge]] and is used today in nearly all mechanical [[wristwatch]]es.

Functional description The escape wheel gives the anchor an impulse to move. While one end is driven forward, the other end engages into the teeth of the gear wheel. This creates a permanent movement - comparable with a rocker.
