The system of operation of the Franklin clock considers that the electrostatic force generated by an electric field is used to move the pendulums that strike two metal bells. [8] [9] The Franklin bells uses a metal rod as a lightning rod to attract current. One bell is connected to the lightning rod and the other bell is connected to the ground.
Diagram of a Zamboni pile The Oxford Electric Bell, believed to be powered by Zamboni pile batteries. The Zamboni pile (also referred to as a Duluc Dry Pile [1]) is an early electric battery, invented by Giuseppe Zamboni in 1812. A Zamboni pile is an "electrostatic battery" and is constructed from discs of silver foil, zinc foil, and paper.
