The pendulum length dictates the rate at which the clock runs. A pendulum with a length of 39.1 inches has a 1 second period. To keep the pendulum swinging, a clutch rod gives the pendulum a kick on each swing. As oil thickens, dust collects, and friction changes, the power supplied to the pendulum can drop the swing angle from 4 degrees to 3 degrees resulting in an 11 second gain per day. Also changes in temperature can change the length of the pendulum and the timing of the swing resulting in gains of time in the winter and a loss of time in the summer.

"The Four Parts of a Mechanical Pendulum Clock"
specifically an E. Howard Tower Clock
