Springfield Model 1868
The Springfield Model 1868 was one of the rifles which used the trapdoor breechblock design developed by Erskine S. Allin. History and Design Originally, the trapdoor Springfields were created to convert Springfield Model 1863 rifled muskets to breech-loading rifles at a relatively low cost. This conversion consisted of replacing the percussion lock with the breech-loading trapdoor mechanism, and relining the barrels to convert them from .58 to .50 caliber. This proved problematic, because in the field, the lining tended to separate from the barrel. To correct this problem, the Model 1868 used a new barrel instead of relining the original older barrel. The new barrel was slightly shorter, 32.5 inches, compared to the 36.5-inch barrel used on the Springfield Model 1866. The shorter barrel was affixed using only two barrel bands, instead of the three used on the Model 1866. Since it lacked the middle barrel band, the sling was affixed to the upper barrel band instead. The Mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breech-loading Rifle
A breechloader is a firearm in which the user loads the ammunition (cartridge or shell) via the rear (breech) end of its barrel, as opposed to a muzzleloader, which loads ammunition via the front ( muzzle). Modern firearms are generally breech-loading – except for replicas of vintage weapons. Early firearms before the mid-19th century were almost entirely muzzle-loading. Mortars and the Russian GP-25 grenade launcher are the only muzzleloaders remaining in frequent modern usage. However, referring to a weapon specifically as breech loading is mostly limited to single-shot or otherwise non-repeating firearms, such as double-barreled shotguns. Breech-loading provides the advantage of reduced reloading time, because it is far quicker to load the projectile and propellant into the chamber of a gun/cannon than to reach all the way over to the front end to load ammunition and then push them back down a long tube – especially when the projectile fits tightly and th ...

Hinged Breechblock Rifles
A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation: all other Translation (geometry), translations or rotations being prevented, and thus a hinge has one degree of freedom. Hinges may be made of Flexure bearing, flexible material or of moving components. In biology, many joints function as hinges, like the elbow joint. History Ancient remains of stone, marble, wood, and bronze hinges have been found. Some date back to at least Ancient Egypt. In Ancient Rome, hinges were called wikt:cardo#Latin, cardō and gave name to the goddess Cardea and the main street Cardo. This name cardō lives on figuratively today as "the chief thing (on which something turns or depends)" in words such as ''wikt:cardinal#English, cardinal''. According to the OED, the English word hinge is related to ''wikt:hang#English, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Springfield Rifle
The term Springfield rifle may refer to any one of several types of small arms produced by the Springfield Armory in Springfield, Massachusetts, for the United States armed forces. In modern usage, the term "Springfield rifle" most commonly refers to the Springfield Model 1903 for its use in both world wars. There were also numerous limited production, experimental, marksmanship, and sporting rifles produced by the Springfield Armory which are referred to as "Springfield rifles". Some examples of the smoothbore Springfield Model 1842 musket that were later modified with rifling and used during the American Civil War may also be referred to as "Springfield rifles". Rifled musket: * Springfield Model 1855 – .58 caliber Maynard tape primer percussion lock rifled musket. * Springfield Model 1861 – .58 caliber percussion lock rifled musket. * Springfield Model 1863 – .58 caliber percussion lock rifled musket. Single-shot rifle: * Springfield Model 1865 – .58-60 calibe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percussion Rifle
The percussion cap or percussion primer, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition. This crucial invention gave rise to the cap lock mechanism or percussion lock system using percussion caps struck by the hammer to set off the gunpowder charge in percussion guns including percussion rifles and cap and ball firearms. Any firearm using a caplock mechanism is a percussion gun. Any long gun with a cap-lock mechanism and rifled barrel is a percussion rifle. Cap and ball describes cap-lock firearms discharging a single bore-diameter spherical bullet with each shot. Description The percussion cap is a small cylinder of copper or brass with one closed end. Inside the closed end is a small amount of a shock-sensitive explosive material such as mercuric fulminate (discovered in 1800; it was the only practical detonator used from about 1850 to the early 20th c ...

Sharps Rifle
Sharps rifles are a series of large-bore, single-shot, falling-block, breech-loading rifles, beginning with a design by Christian Sharps in 1848 and ceasing production in 1881. They were renowned for long-range accuracy. By 1874 the rifle was available in a variety of calibers, and it was one of the few designs to be successfully adapted to metallic cartridge use. The Sharps rifles became icons of the American Old West with their appearances in many Western-genre films and books. Perhaps as a result, several rifle companies offer reproductions of the Sharps rifle. History Sharps' initial rifle was patented September 12, 1848, and manufactured by A. S. Nippes at Mill Creek in Philadelphia, Pennsylvania, in 1850. The second model used the Maynard tape primer, and surviving examples are marked ''Edward Maynard - Patentee 1845''. In 1851, the second model was brought to the Robbins & Lawrence Company (R&L) of Windsor, Vermont, where the Model 1851 was developed for mass produc ...

Repeating Rifle
A repeating rifle is a single- barreled rifle capable of repeated discharges between each ammunition reloads. This is typically achieved by having multiple cartridges stored in a magazine (within or attached to the gun) and then fed individually into the chamber by a reciprocating bolt, via either a manual or automatic action mechanism, while the act of chambering the round typically also recocks the hammer/ striker for the following shot. In common usage, the term "repeating rifle" most often refers specifically to manual repeating rifles (e.g. lever-action, pump-action, bolt-action, etc.), as opposed to self-loading rifles, which use the recoil and/or blowback of the previous shot to cycle the action and load the next round, even though all self-loading firearms are technically a subcategory of repeating firearms. Repeating rifles were a significant advance over the preceding single-shot breechloading rifles when used for military combat, as they allowed a much greater rat ...

Spencer Rifle
The Spencer repeating rifles and carbines were 19th-century American lever-action firearms invented by Christopher Spencer. The Spencer was the world's first military metallic-cartridge repeating rifle, and over 200,000 examples were manufactured in the United States by the Spencer Repeating Rifle Co. and Burnside Rifle Co. between 1860 and 1869. The Spencer repeating rifle was adopted by the Union Army, especially by the cavalry, during the American Civil War but did not replace the standard issue muzzle-loading rifled muskets in use at the time. Among the early users was George Armstrong Custer. The Spencer carbine was a shorter and lighter version designed for the cavalry. Design The Spencer is a lever-action repeating rifle designed by Christopher Spencer in 1860. It uses a falling breechblock mounted in a carrier. Firing forces are contained by the receiver at the rear of the breechblock. Actuating the loading lever causes the breechblock to fall. Once the breechblo ...

45-70
The .45-70 rifle cartridge, also known as the .45-70 Government, was developed at the U.S. Army's Springfield Armory for use in the Springfield Model 1873, which is known to collectors as the "Trapdoor Springfield." The new cartridge was a replacement for the stop-gap .50-70 Government cartridge, which had been adopted in 1866, one year after the end of the American Civil War. Nomenclature The new cartridge was completely identified as the ''.45-70-405'', but was also referred to as the ".45 Government" cartridge in commercial catalogs. The nomenclature of the time was based on three properties of the cartridge: * .45: nominal diameter of bullet, measured in decimal inches, i.e., 0.458 inches (11.63 mm); * 70: weight of black powder, measured in grains, i.e., 70 grains (4.56 g); * 405: weight of lead bullet, measured in grains, i.e., 405 grains (26.38 g). The minimum acceptable accuracy of the .45-70 from the 1873 Springfield was approximately at , however, the heavy, slo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Springfield Model 1866
The Springfield Model 1866 was the second iteration of the Allin-designed trapdoor breech-loading mechanism. Originally developed as a means of converting rifle muskets to breechloaders, the Allin modification ultimately became the basis for the definitive Springfield Model 1873, the first breech-loading rifle adopted by the United States War Department for manufacture and widespread issue to U.S. troops. The Model 1866 corrected problems encountered with the prototypical Springfield Model 1865, in particular a simplified and improved extractor and a superior .50 caliber centerfire cartridge (the Model 1865 used a .58 caliber rimfire cartridge with mediocre ballistics), among many other less significant changes. It employed a robust version of the trapdoor breechblock design originated by Erskine S. Allin, Master Armorer of the Springfield Armory. Approximately 25,000 .58 caliber Springfield Model 1863 rifled muskets were converted by Springfield Armory for use by U.S. troo ...
