That's going to get tedious quite quickly, so what about automating An increase in temperature would cause the pendulum rod to expand, but the mercury in the container would also expand and its level would rise slightly in the container, moving the center of gravity of the pendulum up toward the pivot. Each swing of the pendulum a pallet releases a tooth of the escape wheel. The mechanism inside counts these impulses and converts them into rotations of the hands-on clock face, indicating the time.
