		His invention of the percussion cap deprived the pigeons of their early warning system, both by avoiding the initial puff of smoke from the flintlock powder pan, as well as shortening the time interval between the trigger pull and the shot leaving the muzzle.
		The alteration of the military flintlock to the percussion musket was easily accomplished by replacing the powder pan with a perforated nipple, and by replacing the cock or hammer which held the flint by a smaller hammer formed with a hollow made to fit around the nipple when released by the trigger.
		The detonating cap, thus invented and adopted, brought about the invention of the modern cartridge case, and rendered possible the general adoption of the breech-loading principle for all varieties of rifles, shotguns and pistols.

	Back-flash check for muzzleloaders - US Patent 6226916 (Site not responding. Last check: 2007-10-21)
		A tendency for the protective membranes of percussion caps to lodge within a nipple not having back-flash was cured by the use of an actuator retainer that directs the actuator to the side of the valve chamber during ignition.
		Percussion caps are ignited by striking the outside of the bottom of the cup and percussively compressing the ignition source material against the surface of the end of the tube.
		The use of a percussion cap with a flash chamber in which the cross sectional area of the flash chamber is reduced to 0.008 square inches within 0.23 inches of the nipple anvil will provide a release of the spent cap when used with any check valve.

	From flintlock to in-line guns
		Percussion-cap side-locks use a small percussion cap that fits over a nipple on the side of the gun at the rear of the barrel.
		Percussion caps are more reliable than flintlocks but still misfire sometimes because the flame must move a relatively long distance through the nipple and make a right-angle turn before reaching the powder.
		The primer's flame is about the same temperature as the percussion cap flame (roughly 3,000 degrees), but the shotgun primer produces a considerably larger flame, which results in dramatic improvement in powder ignition.

	Encyclopedia: Percussion cap
		(See caplock mechanism.) The caplock mechanism was the successor of the flintlock mechanism in firearm technology, and used a percussion cap struck by the hammer to set off the main charge, rather than using a piece of flint to strike a steel frizzen.
		Joshua Shaw - an English born American immigrant - is generally credited with the development of the first metallic percussion cap in 1814.
		A flintlock is a firearm that operates in the following manner: The operator loads the gun, usually from the barrel end, with fl 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...

	Toy Cap Guns
		Cap guns were originally made of cast iron, but after World War II were made of zinc alloy, and most newer models are made of plastic.
		Cap guns get their name from the small discs of explosive compounds that provide the noise and smoke, effectively the same as the separate percussion cap used to replace the flintlock in real firearms.
		Cap guns in the United States must be manufactured with a bright orange, red, or yellow tip placed over the "muzzle" of the cap gun, or with the entire gun made in these or other bright colors.

	Percussion cap dispensing device - Patent 4845874
		The caps can then be loaded onto the weapon nipple by pushing the nipple into the hole and extracting a cap, whereupon the next cap becomes available at the hole under the force of the compression coil spring.
		Each percussion cap is installed on a nipple which, when the weapon is fired, is struck by a hammer to ignite the charge.
		Thus, the caps are placed, one at a time, through hole 14 and allowed to follow the follower, sliding down the inside of sleeve 12, until the spring is essentially fully compressed and the desired number of caps has been placed in the sleeve.

	Percussion cap nipple - Patent 4186506
		The percussion cap is designed to fit snugly over the nipple in a position to be struck by the hammer of the firearm.
		When struck, an explosive fulminate in the base of the percussion cap produces a quantity of burning gas in the nipple, and this gas is forced under considerable pressure into the ignition chamber of the firearm, igniting the propellant charge therein.
		The outside of cap receiving section 42a is slightly tapered for receiving a similarly tapered percussion cap such as cap 14.

	Weapons, Part 2
		Percussion muskets, in contrast, are fired using a waterproof percussion cap, which ignites the powder charge in the barrel.
		The flintlocks, while slightly faster to load than their percussion counterparts, were never too reliable, even under ideal conditions (out of every few shots, at least one would "flash" the powder in the pan, without igniting the main charge in the barrel), and in the rain at Mill Springs, most barely functioned at all.
		The confusion, fear, and excitement of combat caused many soldiers to fumble in their cartridge or cap boxes, even dropping unused rounds onto the ground, forgotten (to be found later by relic collectors, their bullets unfired and in pristine condition).

		The percussion cap was the key to making reliable rotating-block guns (revolvers) which would fire reliably, and in the early 1800s several manufacturers began producing these multiple-shot sidearms in mass quantities.
		The percussion cap firing mechanism gave an individual soldier a weapon of precision and reliability which was used to devastating effect in the U.S. Civil War.

		The percussion cap was easier to load, more weather resistant and more reliable, so by the time of America's civil war, both Union and Confederate armies used percussion-cap guns exclusively.
		The percussion cap was made possible by the discovery of a chemical compound called mercuric fulminate or fulminate of mercury.
		The percussion lock is exactly the same as the flintlock in terms of the mainspring, hammer, tumbler, sear and sear spring.

		The residue from explosive materials used in blank or percussive charges is extremely corrosive to the internal workings of the weapon; so let me remind you that all discharged weapons must be thoroughly cleaned within 12 hours of having been fired.

		Besides the roll caps which he invented in the early 1840's Dr. Maynard is also recognized as the inventor of one of the first efficient breech loading cavalry carbines.
		The common cap fit snugly over the cone and when fired it performed the same was as the Maynard cap, the only difference being that the spent cap had to be removed by hand and a new one put on the cone before the weapon was fired again.
		By 1861 it was decided to omit the Maynard primer in favor of the common cap in future U.S. arms as the Maynard primer had a tendency to mis-feed and exposure to any moisture rendered the rolls of caps useless.

		The caps mentioned on this subject earlier were of the musket "hat" type from the 1830's, the caps we had were at least 10-15 years newer design, not having the flattened rim and smaller in dia., the Green River Hawken had a no.11 nipple that was a little smaller dia.
		These caps have laid in storage all their life and probably in the best of possible conditions, as had the new percussion caps, so other than age the test was really not a test, other than the original caps would still fire.
