Flintlock
A flintlock is a firearm that operates in the following manner:
- The operator loads the gun, usually from the barrel end, with black powder followed by shot or a bullet wrapped in a paper patch, all rammed down with a special rod;
- A hammer tightly holding a shaped bit of flint is cocked to half-cock;
- The flash pan is primed with a small amount of very finely ground powder and its lid is closed;
- The hammer is moved from half-cock to full-cock;
- The gun is aimed and the trigger pulled, releasing the hammer;
- The flint strikes the frizzen, a piece of steel or iron on the flashpan lid, opening the lid;
- The contact between flint frizzen produces a spark that is directed into the flashpan;
- The powder ignites, and the flame passes through a small hole in the pan that leads to the firing chamber, igniting the powder there; and
- The gun discharges.
The flintlock was in use as the standard weapon used by the military and civilians all over the world for over two centuries, and has left a mark on the English language.
- Lock, stock and barrel: The three parts of a flintlock, this phrase means "the whole thing".
- Going off half cocked: The half-cock position is the safety on a flintlock. Going off from a half-cocked state means someone has done something prematurely.
- Flash in the pan: If the flint ignites the priming powder in the flashpan but does not ignite the main charge in the barrel, that is a flash in the pan. It indicates an event that has a large, dramatic buildup, but fizzles out before significant result.
