Trapdoor Mechanism
In firearms, a trapdoor is a form of breech-loading mechanism for rifles in which a hinged breechblock rotates up and forward, resembling the movement of a trapdoor. The Springfield models 1865 and 1873 were best known for first employing this type of action. Specifications The ''trapdoor'' ''mechanism'' employed a hinged breechblock that rotated up and forward, resembling the movement of a trapdoor, to open the breech of the rifle and permit insertion of a cartridge. The hinged breechblock caused these rifles to be named "Trapdoor Springfields". The conversion from musket to breechloader was done by milling open the barrel's breech section and inserting a hinged ''trapdoor'' fastened to the top of the barrel. A thumb-operated cam latch at the rear of the breechblock held it shut when in closed position. The rack-type system extractor was withdrawn automatically as the breechblock was opened and snapped back at the end of its stroke. The firing pin was housed within the bre ...

Eli Whitney
Eli Whitney Jr. (December 8, 1765January 8, 1825) was an American inventor, widely known for inventing the cotton gin, one of the key inventions of the Industrial Revolution that shaped the economy of the Antebellum South. Although Whitney himself believed that his invention would reduce the need for enslaved labor and help hasten the end of southern slavery, Whitney's invention made upland short cotton into a profitable crop, which strengthened the economic foundation of slavery in the United States and prolonged the institution. Despite the social and economic impact of his invention, Whitney lost many profits in legal battles over patent infringement for the cotton gin. Thereafter, he turned his attention into securing contracts with the government in the manufacture of muskets for the newly formed United States Army. He continued making arms and inventing until his death in 1825. Early life and education Whitney was born in Westborough, Massachusetts, on December 8, 1765, ...

Springfield Model 1863
The Springfield Model 1863 was a .58 caliber rifled musket manufactured by the Springfield Armory and independent contractors between 1863 and 1865. The Model 1863 was only a minor improvement over the Springfield Model 1861. As such, it is sometimes classified as just a variant of the Model 1861. The Model 1861, with all of its variants, was the most commonly used longarm in the American Civil War, with over 700,000 manufactured. The Model 1863 also has the distinction of being the last muzzle-loading longarm produced by the Springfield Armory. The Model 1863 was produced in two variants. The Type I eliminated the band springs and replaced the flat barrel bands with oval clamping bands. It also featured a new ramrod, a case-hardened lock, a new hammer, and a redesigned bolster (percussion chamber). Several of these modifications were based upon Colt's contract Model 1861, known as the "Colt special". 273,265 Type I variants were manufactured in 1863. The Type II is sometim ...

Magazine (firearms)
A magazine is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a " clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine. Magazines come in many shapes and sizes, from tubular magazines on lever-action and pump-action firearms that may tandemly hold several rounds, to detachable box and drum magazines for automatic rifles and light machine guns that may hold more than one hundred rounds. Various jurisdictions ban what they define as "high-capacity magazines". Nomenclature With the increased use of se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rate Of Fire
Rate of fire is the frequency at which a specific weapon can fire or launch its projectiles. This can be influenced by several factors, including operator training level, mechanical limitations, ammunition availability, and weapon condition. In modern weaponry, it is usually measured in rounds per minute (RPM or round/min) or rounds per second (RPS or round/s). There are three different measurements for the rate of fire: cyclic, sustained, and rapid. Cyclic is the maximum rate of fire given only mechanical function, not taking into account degradation of function due to heat, wear, or ammunition constraints. Sustained is the maximum efficient rate of fire given the time taken to load the weapon and keep it cool enough to operate. Finally, rapid is the maximum reasonable rate of fire in an emergency when the rate of fire need not be upheld for long periods. Overview For manually operated weapons such as bolt-action rifles or artillery pieces, the rate of fire is governed primarily ...
