Matchlock
A matchlock or firelock is a historical type of firearm wherein the gunpowder is ignited by a burning piece of flammable cord or twine that is in contact with the gunpowder through a mechanism that the musketeer activates by pulling a lever or Trigger (firearms), trigger with their finger. This firing mechanism was an improvement over the hand cannon, which lacked a trigger and required the musketeer or an assistant to apply a match directly to the gunpowder by hand. The matchlock mechanism allowed the musketeer to apply the match himself without losing his concentration. Description The classic matchlock gun held a burning slow match in a clamp at the end of a small curved lever known as the ''serpentine''. Upon the pull of a lever (or in later models a trigger) protruding from the bottom of the gun and connected to the serpentine, the clamp dropped down, lowering the smoldering match into the flash pan and igniting the priming powder. The flash from the primer traveled throug ...
