Watch chains 2
Chains are also used in clockwork. They serve e. g. to compensate for the decreasing spring force of the lift by pulling on a larger radius of a bevel gear and thereby compensating for the torque (force x radius or lever arm = torque).
This chain resembles a very scaled down bicycle chain. For size comparison, the chain is photographed with a match head. They were often made by child labor.
Manufacture: 18th century
