Description:
The escapement mechanism regulates the energy of the falling weight (shown behind the brass pendulum) to the oscillating pendulum. Early esacpements were the verge and folliot (X-1) and the anchor. In Model X-4, the weight at the top was designed to change the period of the device. The French were not quick to adapt to the anchor escapement that replaced most verge and foliet escapements in the 18th century. However the pin escapement, which may have had several inventors, was widely used in French tower clocks. It was also used by the American clock maker Seth Thomas in their tower clocks. One example is the famous landmark tower clock at Cornell University, Ithaca New York, which was installed in 1876.
