Alarm Gun
The blunderbuss is a firearm with a short, large caliber barrel which is flared at the muzzle and frequently throughout the entire bore, and used with shot and other projectiles of relevant quantity or caliber. The blunderbuss is commonly considered to be an early predecessor of the modern shotgun, with similar military and defensive use. It was effective only at short range, lacking accuracy at long distances. A blunderbuss in handgun form was called a '' dragon'', and it is from this that the term '' dragoon'' evolved. Etymology The term "blunderbuss" is of Dutch origin, from the Dutch word ''donderbuis'', which is a combination of ''donder'', meaning "thunder", and ''buis'', meaning "pipe" (Middle Dutch: ''busse'', box, tube, from Late Latin, ''buxis'', box, from Ancient Greek ''pyxίs'' (πυξίς), box: esp. from boxwood). The transition from ''donder'' to ''blunder'' is thought by some to be deliberate; the term ''blunder'' was originally used in a transitive sens ...

Flintlock Blunderbuss Tipoo Sahib Seringapatam 1793 1794
Flintlock is a general term for any firearm that uses a flint-striking ignition mechanism, the first of which appeared in Western Europe in the early 16th century. The term may also apply to a particular form of the mechanism itself, also known as the '' true flintlock'', that was introduced in the early 17th century, and gradually replaced earlier firearm-ignition technologies, such as the matchlock, the wheellock, and the earlier flintlock mechanisms such as snaplock and snaphaunce. The true flintlock continued to be in common use for over two centuries, replaced by percussion cap and, later, the cartridge-based systems in the early-to-mid 19th century. Although long superseded by modern firearms, flintlock weapons enjoy continuing popularity with black-powder shooting enthusiasts. History French court gunsmith Marin le Bourgeoys made a firearm incorporating a flintlock mechanism for King Louis XIII shortly after his accession to the throne in 1610. However, firearms usi ...

Muzzle Blast
A muzzle blast is an explosive shockwave created at the muzzle of a firearm during shooting. Before a projectile leaves the gun barrel, it obturates the bore and "plugs up" the pressurized gaseous products of the propellant combustion behind it, essentially containing the gases within a closed system as a neutral element in the overall momentum of the system's physics. However, when the projectile exits the barrel, this functional seal is removed and the highly energetic bore gases are suddenly free to exit the muzzle and rapidly expand in the form of a supersonic shockwave (which can be often fast enough to momentarily overtake the projectile and affect its flight dynamics), thus creating the muzzle blast. The muzzle blast is often broken down into two components: an auditory component and a non-auditory component. The auditory component is the loud "Bang!" sound of the gunshot, and is important because it can cause significant hearing loss to surrounding personnel and al ...

Dragon Pistol
A dragon is a reptilian legendary creature that appears in the folklore of many cultures worldwide. Beliefs about dragons vary considerably through regions, but dragons in western cultures since the High Middle Ages have often been depicted as winged, horned, and capable of breathing fire. Dragons in eastern cultures are usually depicted as wingless, four-legged, serpentine creatures with above-average intelligence. Commonalities between dragons' traits are often a hybridization of feline, reptilian and avian features. Scholars believe huge extinct or migrating crocodiles bear the closest resemblance, especially when encountered in forested or swampy areas, and are most likely the template of modern Oriental dragon imagery. Etymology The word ''dragon'' entered the English language in the early 13th century from Old French ''dragon'', which in turn comes from la, draconem (nominative ) meaning "huge serpent, dragon", from Ancient Greek , (genitive , ) "serpent, giant se ...

Brass
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Bess
"Brown Bess" is a nickname of uncertain origin for the British Army's muzzle-loading smoothbore flintlock Land Pattern Musket and its derivatives. The musket design remained in use for over a hundred years with many incremental changes in its design. These versions include the Long Land Pattern, the Short Land Pattern, the India Pattern, the New Land Pattern Musket and the Sea Service Musket. The Long Land Pattern musket and its derivatives, all 0.75 inch calibre flintlock muskets, were the standard long guns of the British Empire's land forces from 1722 until 1838, when they were superseded by a percussion cap smoothbore musket. The British Ordnance System converted many flintlocks into the new percussion system known as the Pattern 1839 Musket. A fire in 1841 at the Tower of London destroyed many muskets before they could be converted. Still, the Brown Bess saw service until the middle of the nineteenth century.

Musketoon
The musketoon is a shorter-barrelled version of the musket and served in the roles of a shotgun or carbine. Musketoons could be of the same caliber as the issue musket or of a much larger caliber, 1.0–2.5 inches (25–63 mm). The musketoon is most commonly associated with naval use, and pirates in particular, though they also served in a carbine role with cavalry. Musketoon barrels were often flared at the muzzle, resembling a cannon or blunderbuss. Description Musketoons had a brass or iron barrel, and used a wheellock, flintlock or caplock firing mechanism, like the typical musket of the period. They were fired from the shoulder like the musket, but the shorter length (barrels were as short as a foot (30 cm) long) made them easier to handle for those in restricted conditions, such as mounted infantry and naval boarding parties. Smaller bore musketoons matched the caliber of the muskets in service, and were generally used the same way, with single musket ball or a b ...
