The Basics of Pendulum Clocks
Ever since the mid 17th century, pendulum clocks have represented one of the most reliable ways to keep time. Obviously the innovations that have come along in the digital age have replaced many older analog clocks, but no digital clock can match the stately charm found in grandfather clocks. The basic parts of a pendulum clock include its face – complete with the hands and numbers necessary to tell time – the weights and the pendulum.
In the case of a grandfather clock, most of the mechanical parts will be encased in a long box that serves as the clock’s base. Typically the pendulum will swing once ever two seconds, and the mechanism will need to be wound on a regular basis. Winding the clock actually entails pulling on the weight and providing it with potential energy. The clock tells time as this weight unwinds.
