"Slot machine A slot machine (American English), known variously as a fruit machine (British English), puggy (Scottish English), the slots (Canadian and American English), poker machine/pokies (Australian English and New Zealand English), or simply slot (British English and American English), is a casino gambling machine with three or more reels which spin when a button is pushed. Slot machines are also known as one-armed bandits because they were originally operated by one lever on the side of the machine, as distinct from a button on the front panel, and because of their ability to leave the player impoverished or in"

The pistol is a magazine fed, self-loading, hammer firing type which was designed with a trigger ""mode"" switch installed on the left-hand side of the slide (actually only a flush inlaid disk with a bisecting groove), toggling between double-action/single-action(DA/SA) pistol mode, and the double-action-only (DAO) or ""revolver"" mode—though, of course, other than the similarity of the trigger mode, the BDM has no resemblance to revolvers. This mode switch is what gives the handgun its name, with BDM standing for ""Browning Dual Mode"" or ""Browning Double Mode"". Variants of the design lacked the mode operating"

It was produced by the Carron ironworks and was at first sold as a system with the gun, mounting, and shot all together. The standard package of shot per gun was 25 roundshot, 15 barshot, 15 double-headed shot, 10 ""single"" grapeshot, and 10 ""single"" canister shot. ""Single"" meant that the shot weighed the same as the roundshot, while some other canister and grapeshot were also included which weighed one and a half times the roundshot. Its invention is"

The Agar Gun, otherwise known as a ""coffee-mill gun"" because of its resemblance to a coffee mill, was invented by Wilson Agar at the beginning of the US Civil War. The weapon featured mechanized loading using a hand crank linked to a hopper above the weapon. The weapon featured a single barrel and fired through the turning of the same crank; it operated using paper cartridges fitted with percussion caps and inserted into metal tubes which acted as chambers; it was therefore functionally similar to a revolver. The weapon was demonstrated to"

"Puckle gun The Puckle gun (also known as the ""Defence gun"") was a primitive crew-served, manually-operated flintlock revolver patented in 1718 by James Puckle (1667–1724) a British inventor, lawyer and writer. It was one of the earliest weapons to be referred to as a ""machine gun"", being called such in a 1722 shipping manifest, though its operation does not match the modern use of the term. However, the Puckle gun was never used during any combat operation or war. Production was highly limited and may have been as few as two guns.

A second lever could be worked rapidly (or in some models, a crank could be turned) to fire each barrel in succession. This earned the weapon its French nickname of ""moulin à café"" (coffee grinder). (A very similar name was earned by the hand-cranked, mechanically loaded, continuous-firing, ""coffee mill gun"" in America during the American Civil War.) The ammunition plate or block had to be removed by hand before another loaded plate could be inserted. Unlike in the Gatling gun and later"

Like its predecessors, the Modelo 1905 has a non-detachable magazine that can be loaded from the top with a stripper clip. The Mannlicher 1900, 1901 and the Modelo 1905 all use the same blowback operating system. Fowler, North, and Stronge describe blowback-operated weapons as using the pressure from the spent round to push a bolt that is located behind the round back and forth against a spring. The pressure forces the slide back against the spring and ejects the spent cartridge."
"Springald A Springald, or espringal, is a mechanical artillery device for throwing large bolts and less commonly stones or Greek fire. It is depicted in a diagram in an 11th-century Byzantine manuscript, but in Western Europe is more evident in the late 12th century and early 13th century. It was constructed on the same principles as a Greek or Roman ballista, but with inward swinging arms. It was also known as a 'skein-bow', and was a torsion device using twisted skeins of silk or sinew to power two bow-arms. Examples have been drawn by Leonardo da Vinci, but at a"

The clasp arm Great Spur Wheel was of wood. It drove three pairs of underdrift millstones, with a fourth pair being driven by the waterwheel. The wind-driven millstones were all French Burr stones, two pairs being diameter and the third pair being diameter. Little is known about the waterwheel except that it was undershot and drove a single pair of millstones on the first floor of the mill, which was the"
"a cannon firing canister shot or grapeshot. Since they were still mounted on a carriage, they could be as hard to aim and move around as a cannon, and the many barrels took as long or longer to reload. They also tended to be relatively expensive since they were more complex than a cannon, due to all the barrels and ignition fuses, and each barrel had to be individually maintained and cleaned. The Gatling gun is one of the best-known early rapid-fire spring loaded, hand cranked weapons and a forerunner of the modern machine gun and rotary cannon. Invented by"

Vollmer originally designed the feed mechanism to accept MG 15 inspired 75-round ""Patronentrommel 34"" spring-loaded saddle-drum magazines. The ""Patronentrommel 34"" was a rather complex magazine for which a filling device existed and requiring ordnance personnel and a special tool to optimize the spring tension for reliable feeding.

"the single shot pistol. New operating mechanisms were created, and due to this, they are still made today. It is the oldest type of pistol, and is often used to hunt wild game. Multi-barreled pistols were common during the same time as single shot pistols. As designers looked for ways to increase fire rates, multiple barrels were added to all guns including pistols. One example of a multi-barreled pistol is the Duck's foot pistol, which generally had either four or eight barrels, although some 20th-century models had three barrels. Around 1850, pistols such as the Jarre harmonica gun were produced"

The Czech word is well documented since the Hussite wars in 1420s. The most common types of pistol are the single shot, and semi-automatic. Single shot handguns were mainly seen during the era of flintlock and musket weaponry where the pistol was loaded with a lead ball and fired by a flint striker, and then later a percussion cap.

QF 1-pounder pom-pom The QF 1 pounder, universally known as the pom-pom due to the sound of its discharge, was a 37 mm British autocannon, the first of its type in the world. It was used by several countries initially as an infantry gun and later as a light anti-aircraft gun. Hiram Maxim originally designed the Pom-Pom in the late 1880s as an enlarged version of the Maxim machine gun.

"had been experimented with for centuries. Notable pre-cartridge era single-shot firearms included matchlock, wheellocks, snaplock, doglock, miquelet locks, flintlock, and percussion cap firearms. Muzzle loaders included Brown Bess muskets, Charleville muskets, Kentucky Rifles, dueling pistols, M1841 Mississippi Rifle, Springfield Model 1861 and many others. There were also breech loading pre-cartridge era single shots such as Hall rifles, Fergussion rifles, Sharps rifles, and several others. Almost all of the early cartridge-fed rifles were single-shot designs, taking advantage of the strength and simplicity of single-shot actions. A good example is the ""trapdoor"" or Allin action used in early cartridge conversions of 1863"

As the name suggests the normal ammunition is peas (usually dried), though other seeds, fruits, improvised darts, or wadded up paper can also be used. The P-26 fighter aircraft was nicknamed the shooter of peas because it has no visible armament (it had two machine guns on the floor of the cockpit shooting through the propeller). It did, however, have a long tube gunsight just forward of the windscreen that"

It first entered service in 1871, eventually replacing the Snider–Enfield, a muzzle-loader converted to the cartridge system. Martini–Henry variants were used throughout the British Empire for 30 years. It combined the dropping-block action first developed by Henry O. Peabody (in his Peabody rifle) and improved by the Swiss designer Friedrich von Martini, combined with the polygonal barrel rifling designed by Scotsman Alexander Henry. Though the Snider was the first breechloader firing a metallic cartridge in regular British service, the Martini was designed from the"

An early improvement was the development of a movable carriage, also water powered, to move the log steadily through the saw blade. A type of sawmill without a crank is known from Germany called ""knock and drop"" or simply ""drop"" -mills. In these drop sawmills, the frame carrying the saw blade is knocked upwards by cams as the shaft turns. These cams are let into"

"Single-shot Single-shot firearms are firearms that hold only a single round of ammunition, and must be reloaded after each shot. The history of firearms began with single-shot designs, and many centuries passed before multi-shot repeater designs became commonplace. Single-shot designs are less complex than revolvers or magazine-fed firearms, and many single-shot designs are still produced by many manufacturers, in both cartridge- and non-cartridge varieties, from zip guns to the highest-quality shooting-match weapons. The vast majority of firearms before the introduction of metallic cartridges in the 1860s were single-shot and muzzle loading. However, multi-barrel, breech loading, revolving, and other multi-shot firearms"

The hammer of the weapon (located on the right side of the receiver like all other percussion fired rifles of the time period) holds the firing pin at the tip. A tooled, milled slot is visible on the head of the bolt canted toward the right side allows a slight opening for the firing pin atop the hammer to strike the rim-fired cartridge, usually the 56-50 rim fire. The bolt was designed for single shot action,"

Early guns were often conversions of earlier cap-and-ball revolvers, modified to accept metallic cartridges loaded from the rear, but later models, such as the Colt Model 1872 ""Open Top"" and the Smith & Wesson Model 3, were designed from the start as cartridge revolvers. In 1873, Colt introduced the famous Model 1873, also known as the Single Action Army, the ""Colt .45"" (not to be confused with Colt made models of the M1911 semi-automatic) or simply, ""the Peacemaker"", one of the most famous handguns ever made."
