Chain element

Fausto Colombo, Giorgio Valentini

1991

Inspired by drawings in the Codex Atlanticus and Madrid Codex I, two different types of chains have been reconstructed within a wooden frame.

Enlarged reproductions of the chain links show that both are made up of a series of elements connected by pins. When used in a pulley for lifting weights, the chain is stronger than a rope, as it can be engaged by the teeth of a gear.

Sometimes Leonardo depicts weights attached to the ends of the chain, suggesting its use for transmitting intermittent motion to a single gear wheel; this solution could be applied to ratchet mechanisms, such as those in clocks.
