Muskets
A musket is a muzzle-loaded long gun that appeared as a smoothbore weapon in the early 16th century, at first as a heavier variant of the arquebus, capable of penetrating plate armour. By the mid-16th century, this type of musket gradually disappeared as the use of heavy armour declined, but ''musket'' continued as the generic term for smoothbore long guns until the mid-19th century. In turn, this style of musket was retired in the 19th century when rifled muskets (simply called rifles in modern terminology) using the Minié ball (invented by Claude-Étienne Minié in 1849) became common. The development of breech-loading firearms using self-contained cartridges, introduced by Casimir Lefaucheux in 1835, began to make muskets obsolete. The first reliable repeating rifles, the 1860 Henry rifle and its 1866 descendent the Winchester rifle, superseded muskets entirely. Repeating rifles quickly established themselves as the standard for rifle design, ending the era of the mus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifled Musket
A rifled musket, rifle musket, or rifle-musket is a type of firearm made in the mid-19th century. Originally the term referred only to muskets that had been produced as a smoothbore weapon and later had their Gun barrel, barrels replaced with Rifling, rifled barrels. The term later included rifles that directly replaced, and were of the same design overall as, a particular model of smoothbore musket. History and development In the early 19th century, both rifles and muskets were in use. Muskets were smoothbore Muzzleloader, muzzle-loading weapons, firing round lead balls or buck and ball ammunition, that were also designed to accept a bayonet. Rifles were similar in that they used the same kind of flintlock or caplock firing mechanism, but the main difference was that their barrels were rifled – that is, their barrels had grooves cut into the interior surface which would cause the bullet to spin as it left the barrel. Rifles have the advantage of long range accuracy, becau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arquebus
An arquebus ( ) is a form of long gun that appeared in Europe and the Ottoman Empire during the 15th century. An infantryman armed with an arquebus is called an arquebusier. The term ''arquebus'' was applied to many different forms of firearms from the 15th to 17th centuries, but it originally referred to "a hand cannon, hand-gun with a hook-like projection or lug on its under surface, useful for steadying it against battlements or other objects when firing". These "hook guns" were in their earliest forms defensive weapons mounted on German city walls in the early 15th century. The addition of a shoulder stock, priming pan, and matchlock mechanism in the late 15th century turned the arquebus into a handheld firearm and also the first firearm equipped with a trigger. The exact dating of the matchlock's appearance is disputed. It could have appeared in the Ottoman Empire as early as 1465 and in Europe a little before 1475. The heavy arquebus, which was then called a musket, was d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Turk(36)
Grand Turk is an island in the Turks and Caicos Islands, a British Overseas Territory, tropical islands in the Lucayan Archipelago of the Atlantic Ocean and northern West Indies. It is the largest island in the Turks Islands (the smaller of the two archipelagos that make up the island territory) with . Grand Turk contains the territory's capital, Cockburn Town, and the JAGS McCartney International Airport. The island is the administrative, historic, cultural and financial centre of the territory and has the second-largest population of the islands at approximately 4,831 people in 2012. The name comes from a species of cactus on the island, the Turk's cap cactus ('' Melocactus intortus''), which has a distinctive cap, reminiscent of an Ottoman fez. In addition, this interpretation of the name received a reaction in the Turkish press on the grounds that it was anachronism. Fez began to be used by the Ottoman Turks in the 19th century, and the "Turk" in the island's name date ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trigger Guard
A trigger guard is a protective loop surrounding the trigger (firearms), trigger of a firearm designed to prevent unwanted contact with the trigger, which may cause an accidental discharge. Other devices that use a trigger-like actuator mechanism, such as inhalers, crossbows and power tools, may also have trigger guards. On rifles with a bottom metal, the trigger guard is often incorporated as part of the bottom metal. Winter trigger guards Some firearms may have their trigger guard removed or repositioned as not to impair use with large cold weather gloves on, especially those intended to be used in arctic conditions. Quite notably, the Accuracy International Arctic Warfare line of rifles have enlarged trigger guards for use in cold climates, primarily northern Sweden.

Nessler Ball
The Nessler ball, or ''balle Nessler'', is a type of muzzle-loading musket bullet. It was developed to increase the accuracy and range of smoothbore muskets and was used in the Crimean War. It featured a short conical-cylindrical soft lead bullet, with a conical hollow in its base. The bullet was designed with a lead skirting. Its intended purpose was to expand under the pressure and obturate the barrel and increase muzzle velocity. The bullet could be quickly removed from a paper cartridge with the gunpowder poured down the barrel and the bullet pressed past the muzzle. It was then rammed home with the ramrod, which ensured that the charge was packed and the hollow base was filled with powder. When fired, the expanding gas pushed forcibly on the base of the bullet, deforming it to form a better seal for consistent velocity, longer range, and accuracy. A similar ball design called the Chace ball (after its inventor W.B. Chace) was developed in 1861 in the United States but was no ...

Metallic Cartridge
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance ( smokeless powder, black powder substitute, or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile. Military and commercial producers continue to pursue the goal of caseless ammunition. Some artillery ammunition uses the same cartridge concept as found in small arms. In other cases, the artillery shell is separate from the propellant charge. A cartridge without a projectile is called a ''blank''; one that is completely inert (contains no active primer and no propellant) is called a '' dummy''; one that faile ...

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] |
Bandolier
A bandolier / bandoleer or a bando is a pocketed belt (clothing), belt for holding either individual Cartridge (firearms), cartridges, belt (firearms), belts of ammunition or United States 40 mm grenades, grenades. It is usually slung sash-style over the shoulder and chest, with the ammunition pockets across the midriff and chest. Though functionally similar, they are distinct from chest rigs, which are designed to hold magazine (firearms), magazines instead. History By the late 15th century, the earliest viable handheld firearms in Europe were the arquebus fitted with a matchlock mechanism. The user kept his shot in a leather pouch and his powder in a Powder flask, flask with a volumetric spout. The spout was calibrated to deliver the proper charge for the user's arquebus. With the advent of the Musket#Heavy arquebus, heavy arquebus (later known as a musket) in the early 16th century, a spout large enough to measure the required powder was impractical. Furthermore, trying to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roller Bearing
In mechanical engineering, a rolling-element bearing, also known as a rolling bearing,ISO 15 is a bearing which carries a load by placing rolling elements (such as balls, cylinders, or cones) between two concentric, grooved rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding. One of the earliest and best-known rolling-element bearings is a set of logs laid on the ground with a large stone block on top. As the stone is pulled, the logs roll along the ground with little sliding friction. As each log comes out the back, it is moved to the front where the block then rolls onto it. It is possible to imitate such a bearing by placing several pens or pencils on a table and placing an item on top of them. See " bearings" for more on the historical development of bearings. A rolling element rotary bearing uses a shaft in a much larger hole, and spheres or cylinders called "rollers" tig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Detent
A detent is a mechanical or magnetic means to resist or arrest the movement of a mechanical device. Such a device can be anything ranging from a simple metal pin to a machine. The term is also used for the method involved. Magnetic detents are most often used to divide a shaft rotation into discrete increments. Magnetic detents are inherent in some types of electric motors, most often stepper motors. Mechanics Arresting movement Ratchet and pawl The ratchet-and- pawl design arrests movements by employing a small gravity- or spring-actuated lever paired with a notched wheel. The lever is mounted on a pivot point in proximity to the wheel. The vertical angle of the sides of the notches that face the direction of rotation desired is generally very acute (45 degrees or less), so that as the wheel rotates in that direction, the end of the lever is easily lifted or pushed out and over the top of a notch. Following this, the lever drops into the next notch and the next et cetera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
