Falling-block Rifles
A falling-block action (also known as a sliding-block or dropping-block action) is a single-shot firearm action in which a solid metal breechblock slides vertically in grooves cut into the breech of the weapon and is actuated by a lever. Description When the breechblock is in the closed (top) position, it seals the chamber from the high pressures created when the cartridge fires and safely transfers the recoil to the action and stock. When the breechblock is in the opened (bottom) position, the rear (breech) end of the chamber is exposed to allow ejection or extraction of the fired case and reloading of an unfired cartridge. It is a very strong action; when the breech is closed, the receiver essentially becomes a single piece of steel (as opposed to other actions that rely on lugs to lock the breech). This type of action is used on artillery pieces, as well as small arms. An additional advantage is the unobstructed loading path, which imposes no limit on the overall length of ...

Ballard Rifle
The Ballard Rifle was a single shot, breechloading longarm used during the American Civil War by Kentucky volunteers. History The Ballard Rifle was designed and patented by Charles H. Ballard in November 1861 in Worcester, Massachusetts. Around 3,000 were made between 1862 and 1865, with some being used for military use in Kentucky Kentucky (, ), officially the Commonwealth of Kentucky, is a landlocked U.S. state, state in the Southeastern United States, Southeastern region of the United States. It borders Illinois, Indiana, and Ohio to the north, West Virginia to the .... Ballard rifles used by Kentucky Volunteers will have Kentucky marked on them. Variants Variants were built by Ball & Williams (1862–1865), Dwight Chapin & Co. (1862–1863), and later by R. Ball & Co. (1865–1867), Merrimack Arms (1867–1868), and Brown Manufacturing (1869–1873). The last and most successful maker was J.M. Marlin Firearms Co., who built more models than any predecessor (187 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peabody Action
The Peabody action was an early form of breechloading firearm action, where the heavy breechblock tilted downwards across a bolt mounted in the rear of the breechblock, operated by a lever under the rifle. The Peabody action most often used an external hammer to fire the cartridge. History Original Peabody action The Peabody action was developed by Henry Oliver Peabody (13 May 1826 Boxford, Massachusetts – 28 June 1903 Hull, Massachusetts)Norwood Historical Society: Henry Oliver Peabody Accessed 21 December 2022. from Boston, Massachusetts, and was first patented on July 22, 1862. While the Peabody was not perfected in time for the American Civil War, a few were entered in the trials of 1864 with favorable reports. Peabody carbines and rifles were made by the ''Providence Tool Company ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martini–Henry
The Martini–Henry is a breech-loading single-shot rifle with a lever action that was used by the British Army. 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 47 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 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 outset as a breechloader and was both faster firing and had a longer range. The Martini–Henry was copied on a large scale by North-West Frontier Province gunsmiths. Their weapons were of a poorer quality than those made by Royal Small Arms Factory, Enfield, but accurately copied down to the proof ma ...

Industrial Furnace
An industrial furnace is a device used to provide heat for an industrial process, typically operating at temperatures above 400 degrees Celsius. These furnaces generate heat by combusting fuel with air or oxygen, or through Electricity, electrical energy, and are used across various industries for applications such as chemical reactions, cremation, Oil refinery, oil refining, and Glass melting furnace, glasswork. The residual heat is expelled as flue gas. While the term industrial furnace encompasses a wide range of high-temperature equipment, one specific type is the direct fired heater, also known as a direct fired furnace or process furnace. Direct fired heaters are primarily used in refinery and petrochemical applications to efficiently transfer heat to process fluids by means of combustion. Unlike other industrial furnaces used in metallurgical furnace, metallurgy or batch ovens, direct fired heaters are optimized for precise temperature control and high thermal efficiency ...

Boilers
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is commo ...

Clinker (waste)
Clinker is a generic name given to waste from industrial processes, particularly those that involve smelting metals, welding, burning fossil fuels and use of a blacksmith's forge, which commonly causes a large buildup of clinker around the tuyere. Clinker often forms a loose, dark deposit consisting of waste materials such as coke (fuel), coke, coal, slag, charcoal, and Gritstone, grit. Clinker often has a glassy look to it, usually because of the formation of molten Silicon dioxide, silica compounds during processing. Clinker generally is much denser than coke, and, unlike coke, generally contains too little carbon to be of any value as fuel. It is also applied to the byproduct of combustion and heating by those who use anthracite or lignite coal-fired boilers. Clinkers can occur naturally, for example in underground deposits of coal that have been altered by heat from coal-seam fires and nearby molten magma; volcanic clinkers are jagged pieces of lava that look similar to in ...

8 Bore
The 8 bore (Commonwealth English), also known as the 8 gauge (American English), is an obsolete caliber used commonly in the 19th-century Black powder, black-powder firearms for Big-game hunting, hunting large dangerous game. Design An 8 bore is a caliber firearm. Historically it was used to fire bullet, solid projectiles from smoothbores, rifling, rifles, and partially rifled ball and shot guns, as well as shot (pellet), shot from muzzleloader, muzzle-loading and Breech-loading weapon, breech-loading shotguns. Later breech loaders were designed to fire Cartridge (firearms), cartridges. History Shot loadings The 8 bore was a popular wildfowling calibre both in muzzleloaders and later cartridge shotguns. 8 bore cartridges were available in multiple lengths including 3-inch, 3¼-inch, 3¾-inch and 4-inch. Solid loadings When the Dutch Republic, Dutch established the Dutch Cape Colony in the 17th century, they soon discovered their muskets were hopelessly inadequate against loc ...

Target Shooting
Shooting sports is a group of competitive and recreational sporting activities involving proficiency tests of accuracy, precision and speed in shooting — the art of using ranged weapons, mainly small arms (firearms and airguns, in forms such as handguns, rifles and shotguns) and bows/crossbows. Shooting sports can be categorized by equipment, shooting distances, targets, time limits and degrees of athleticism involved. Shooting sports may involve both team and individual competition, and team performance is usually assessed by summing the scores of the individual team members. Due to the noise of shooting and the high (and often lethal) impact energy of the projectiles, shooting sports are typically conducted at either designated permanent shooting ranges or temporary shooting fields in the area away from settlements. History Great Britain The National Rifle Association (NRA) was founded in 1859 to raise the funds for an annual national rifle meeting "for the encouragem ...

Hunting
Hunting is the Human activity, human practice of seeking, pursuing, capturing, and killing wildlife or feral animals. The most common reasons for humans to hunt are to obtain the animal's body for meat and useful animal products (fur/hide (skin), hide, bone/tusks, horn (anatomy), horn/antler, etc.), for recreation/taxidermy (see trophy hunting), although it may also be done for resourceful reasons such as removing predators dangerous to humans or domestic animals (e.g. wolf hunting), to pest control, eliminate pest (organism), pests and nuisance animals that damage crops/livestock/poultry or zoonosis, spread diseases (see varmint hunting, varminting), for trade/tourism (see safari), or for conservation biology, ecological conservation against overpopulation and invasive species (commonly called a culling#Wildlife, cull). Recreationally hunted species are generally referred to as the ''game (food), game'', and are usually mammals and birds. A person participating in a hunt is a ...
