Musket
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) and the first reliable repeating rifles produced by Winchester Repeating Arms Company in 1860 also led to their demise. By the time that repeating rifles became common, they were known as simply "rifles", ending the era of the musket. Etymology According to the Online ...

Grand Turk(36)
Grand Turk Island is an island in the Turks and Caicos Islands. 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 center 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 Empire, Ottoman Fez (clothing), fez. History The Lucayan people were the indigenous people of the island, who called it ''Abawana,'' meaning "the First Small Land"''.'' The Spanish later called it Amuana. Grand Turk was first colonised in 1681 by Bermudians, who set up the salt industry in the islands. In 1766 it became the capital of the country. Fo ...

Crossbow
A crossbow is a ranged weapon using an elastic launching device consisting of a bow-like assembly called a ''prod'', mounted horizontally on a main frame called a ''tiller'', which is hand-held in a similar fashion to the stock of a long firearm. Crossbows shoot arrow-like projectiles called '' bolts'' or ''quarrels''. A person who shoots crossbow is called a ''crossbowman'' or an '' arbalist'' (after the arbalest, a European crossbow variant used during the 12th century). Although crossbows and bows use the same launch principle, the difference is that an archer must maintain a bow's draw manually by pitching the bowstring with fingers, pulling it back with arm and back muscles and then holding that same form in order to aim (which distresses the body and demands significant physical strength and stamina); while a crossbow utilizes a locking mechanism to maintain the draw, limiting the shooter's exertion to only pulling the string into lock and then releasing the shot ...

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 ...

Metallic Cartridge
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder 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 the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head (centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin (pinfire, now obsolete); or a li ...

Bandolier
A bandolier or a bandoleer is a pocketed belt for holding either individual bullets, or belts of ammunition. 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 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 flask with a volumetric spout. The spout was calibrated to deliver the proper charge for the user's arquebus. With the advent of the 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 double or triple charge from a flask was time consuming and could create a “missed” charge. A bandolier from whence would hang several little flasks each fil ...

Bandelier Met Kruitmaatjes En Kogelzakje, NG-1149
Bandelier National Monument is a United States National Monument near Los Alamos in Sandoval and Los Alamos counties, New Mexico. The monument preserves the homes and territory of the Ancestral Puebloans of a later era in the Southwest. Most of the pueblo structures date to two eras, dating between 1150 and 1600 AD. The monument is of the Pajarito Plateau, on the slopes of the Jemez volcanic field in the Jemez Mountains. Over 70% of the monument is wilderness, with over one mile of elevation change, from about along the Rio Grande to over at the peak of Cerro Grande on the rim of the Valles Caldera, providing for a wide range of life zones and wildlife habitats. of road and more than of hiking trails are built. The monument protects Ancestral Pueblo archeological sites, a diverse and scenic landscape, and the country's largest National Park Service Civilian Conservation Corps National Landmark District. Two-thirds of the park, , is designated as the Bandelier Wilderness ...

Roller Bearing
In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements (such as balls or rollers) 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 are sets 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 on to 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 cylinders called "rollers" tightly fill the space between t ...

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 that rotation is 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 ...

Percussion Lock
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 cen ...

Flintlock Mechanism
The flintlock mechanism is a type of lock (firearm), lock used on muskets, rifles, and pistols from the early 17th to the mid-19th century. It is commonly referred to as a "flintlock" (without the word ''mechanism''), though that term is also commonly used for the weapons themselves as a whole, and not just the lock mechanism. The flintlock mechanism, also known as the true flintlock, was developed in France in the early 17th century. It quickly replaced earlier technologies, such as the matchlock and wheellock and the earlier flintlocks. It continued to be in common use for over two centuries, until it was finally replaced by the percussion lock. History Flintlock firing mechanisms made their appearance in the 16th century in the form of the snaplock, the snaphance, the miquelet, and the doglock. The so-called ''true flintlock'' was developed in France in the early 17th century. Though its exact origins are not known, credit for the development of the true flintlock is usually gi ...

Wheel Lock
A wheellock, wheel-lock or wheel lock is a friction-wheel mechanism which creates a spark that causes a firearm to fire. It was the next major development in firearms technology after the matchlock and the first self-igniting firearm. Its name is from its rotating steel wheel to provide ignition. Developed in Europe around 1500, it was used alongside the matchlock and later the snaplock (1540s), the snaphance (1560s) and the flintlock (c. 1610s). Design The wheellock works by spinning a spring-loaded steel wheel against a piece of pyrite to generate intense sparks, which ignite gunpowder in a pan, which flashes through a small touchhole to ignite the main charge in the firearm's barrel. The pyrite is clamped in vise jaws on a spring-loaded arm (or 'dog'), which rests on the pan cover. When the trigger is pulled, the pan cover is opened, and the wheel is rotated, with the pyrite pressed into contact. A close modern analogy of the wheellock mechanism is the operation of a lighter ...
