Automatic striker

Acciarino automatico a pietra focaia

The model represents one of Leonardo's ideas for lighting repeatedly the charge of a firearm. It is one of the most beautiful drawings on this subject, well defined and full of details. The device consists of a spiral spring connected to an upper wheel by an articulated chain. When the wheel turns, it rubs against the flint stone (on the left) generating a spark. The trigger is on the right. The articulated three-mesh chain is magnified and rebuilt on the side.

Codex Atlanticus, sheet 158 1497-1500
