Flint mill, английский
Flintlock, английский
This early product of the industrial revolution replaced the slow-match and greatly increased the speed of naval gunfire. the device consists of a spring-powered hammer into which a flint is inserted. when the hammer is released by pulling a lanyard the flint strikes a steel element known as the frizzen, creating a spark which ignites a small quantity of gunpowder sitting in a pan above the touch-hole (vent), this in turn ignites the main charge. in 1778, captain (later rear admiral) sir charles douglas, recommended the use of flintlocks for naval ordnance and, when the admiralty rejected the idea, bought musket locks at his own expense and installed them on his own ship. by 1790 the admiralty had finally been convinced of the superiority of this form of ignition and installed them throughout the navy. (army gunners were yet more conservative and—even though the infantry introduced “brown bess” flintlock muskets in the early 1720s—flintlocks were not adopted for land artillery until thirty years after the navy, and even then the gunners retained their portfires as backup.)
