3-inch Ordnance Rifle
The 3-inch ordnance rifle, model 1861 was a wrought iron muzzleloading rifled cannon that was adopted by the United States Army in 1861 and widely used in field artillery units during the American Civil War. It fired a projectile to a distance of at an elevation of 5°. The 3-inch rifle was not as effective in firing canister shot as the heavier 12-pounder Napoleon, but it proved to be highly accurate at longer ranges when firing common shell or spherical case shot. There was only one reported case of a 3-inch ordnance rifle bursting in action. This was in stark contrast to the similarly sized cast iron 10-pounder Parrott rifles which occasionally burst without warning, inflicting injury on the gun crews. The Confederate States of America lacked the technology to manufacture reliable copies of the 3-inch ordnance rifle. However, the Confederate States Army respected the weapons and employed those captured from Federal forces. Background Griffen gun By 1835, so many 6-pounder ...

American Civil War
The American Civil War (April 12, 1861May 26, 1865; also known by Names of the American Civil War, other names) was a civil war in the United States between the Union (American Civil War), Union ("the North") and the Confederate States of America, Confederacy ("the South"), which was formed in 1861 by U.S. state, states that had Secession in the United States, seceded from the Union. The Origins of the American Civil War, central conflict leading to war was a dispute over whether Slavery in the United States, slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction. Timeline of events leading to the American Civil War, Decades of controversy over slavery came to a head when Abraham Lincoln, who opposed slavery's expansion, won the 1860 presidential election. Seven Southern slave states responded to Lincoln's victory by seceding f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M1841 6-pounder Field Gun
The M1841 6-pounder field gun was a bronze smoothbore muzzleloading cannon that was adopted by the United States Army in 1841 and used from the Mexican–American War to the American Civil War. It fired a round shot up to a distance of at 5° elevation. It could also fire canister shot and spherical case shot (shrapnel). The cannon proved very effective when employed by light artillery units during the Mexican–American War. The cannon was used during the early years of the American Civil War, but it was soon outclassed by newer field guns such as the M1857 12-pounder Napoleon. In the U.S. Army, the 6-pounders were replaced as soon as more modern weapons became available and none were manufactured after 1862. However, the Confederate States Army continued to use the cannon for a longer period because the lesser industrial capacity of the South could not produce new guns as fast as the North. Background By the early 1800s gun-founders knew that two metals were suitable for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tredegar Iron Works
The Tredegar Iron Works in Richmond, Virginia, was the biggest ironworks in the Confederacy during the American Civil War, and a significant factor in the decision to make Richmond the Confederate capital. Tredegar supplied about half the artillery used by the Confederate States Army, as well as the iron plating for CSS ''Virginia'', the first Confederate ironclad warship, which fought in the historic Battle of Hampton Roads in March 1862. The works avoided destruction by troops during the evacuation of the city, and continued production through the mid-20th century. Now classified as a National Historic Landmark District, the site serves as the main building of the American Civil War Museum. The name Tredegar derives from the Welsh industrial town that supplied much of the company's early workforce. History Founding (1836–1841) In 1836, a group of Richmond businessmen and industrialists led by Francis B. Deane, Jr. set about to capitalize on the growing railroad boom ...

Wiard Rifle
The Wiard rifle refers to several weapons invented by Norman Wiard, most commonly a semi-steel light artillery piece in six-pounder and twelve-pounder calibers. About 60 were manufactured between 1861 and 1862 during the American Civil War, at O'Donnell's Foundry, New York City: "although apparently excellent weapons, [they] do not seem to have been very popular". Wiard also designed a rifled steel version of the Dahlgren gun#Army use of boat howitzers, Dahlgren boat howitzer (a 12-pounder (5.44 kg) weapon with a bore), among other gun types.Olmstead 1997, pp. 177-178 Further, Wiard unsuccessfully attempted to develop a rifled gun for the US Navy and proposed a gun. In 1881 he unsuccessfully proposed various "combined rifle and smoothbore" weapon conversions of Rodman guns and Parrott rifles.Olmstead 1997, pp. 144-146 Wiard described two calibers: a six-pounder (2.72 kg) rifling, rifle with a bore, and a twelve-pounder (5.44 kg) smoothbore weapon with a bore.

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, charcoal (which is mostly carbon), and potassium nitrate, potassium nitrate (saltpeter). The sulfur and charcoal act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building Pipeline transport, pipelines, tunnels, and road#Construction, roads. Gunpowder is classified as a Explosive#Low, low explosive because of its relatively slow decomposition rate, low ignition temperature and consequently low brisance, brisance (breaking/shattering). Low explosives deflagration, deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonation, detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an sufficiency of disclosure, enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private la ...
