Rolling-block
A rolling-block action is a form of firearm action where the sealing of the breech is done with a specially shaped breechblock able to rotate on a pin. The breechblock is shaped like a section of a circle. The breechblock is locked into place by the hammer, thus preventing the cartridge from moving backwards at the moment of firing. By cocking the hammer, the breechblock can be rotated freely to reload the weapon. History The Remington Rolling Block rifle is one of the most successful single-shot weapons ever developed. It is a strong and simple action, very reliable, and not prone to be jammed by dirt or rough usage. It was invented by Leonard Geiger during the United States Civil War and patented in 1863, who (along with his partner, Charles Alger) negotiated a royalty deal with Remington when they put it into production as the so-called "split breech" action late in the war. That design was re-engineered by Joseph Rider in 1865 and called the "Remington System". The first ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Remington M1867
The Remington M1867 was a rolling-block rifle, the first rifle using metallic cartridges to be adopted by the Norwegian and Swedish armies. Nominally it had a caliber of 4 decimal lines, but the actual caliber was 3.88 Norwegian decimal lines or 4.1 Swedish decimal lines (12.17 mm), and it fired a rimfire round with a 12.615 mm (.497 in) lead bullet. The 12.17 mm caliber was chosen because the Swedish army had approximately 30,000 new muzzle-loading M1860 and breech-loading M1864 rifles in 12.17 mm caliber in stock, rifles that were suitable for conversion to M1867 rolling-block rifles. With the exception of the first 10,000 rifles and 20,000 actions (for conversions of older rifles), which were made by Remington in the US, all Remington M1867 rifles and carbines were made under license in Norway and Sweden, by Kongsberg Vaapenfabrik in Norway, and by Husqvarna Vapenfabriks Aktiebolag and Carl Gustafs stads Gevärsfaktori in Sweden with the two Swedish manufact ...

Springfield Model 1870 Remington—Navy
The Springfield Model 1870 rolling-block U.S. Navy rifle was a shipboard small arm for use by the United States Navy, employing the Remington Arms Company rolling-block design, and manufactured under a royalty agreement with Remington. Note: Springfield Model 1870 may also refer to the Springfield Model 1870 rifle. One of the rifles which used the trapdoor breechblock design developed by Erskine S. Allin. Origin During the U.S. Civil War, Joseph Rider experimented with several breech-loading weapon designs. In 1865, he was issued the first patent for what would evolve into the Remington rolling-block action. The Remingtons continued to invest in Rider's work, and met with Ordnance Department officials in the hope of interesting them in this new design called the "Remington System". The U.S. Navy Ordnance Department became interested in the design, and purchased several different models of rifles from 1867 through 1869. Field trials of these various rifles yielded mostly posit ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Breechblock
A breechblock (or breech block) is the part of the firearm action that closes the breech of a breech loading weapon (whether small arms or artillery) before or at the moment of firing. It seals the breech and contains the pressure generated by the ignited propellant. Retracting the breechblock allows the chamber to be loaded with a cartridge. Breechblocks are categorised by the type or design of the mechanism by which it is locked or closed for firing. The firearm action more fully refers to the mechanism by which the operator actuates the opening and closing of the breech. Variants A way of closing the breech or chamber is an essential part of any breech-loading weapon or firearm. Perhaps the simplest way of achieving this is a break-action, in which the barrel, forestock and breech pivot on a hinge that joins the front assembly to the rear of the firearm, incorporating the rear of the breech, the butt and usually, the trigger mechanism. A breechblock is a separate compone ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bridesburg, Philadelphia
Bridesburg is the northernmost neighborhood in the River Wards section of Philadelphia, Pennsylvania, United States. Bridesburg is an historically German and Irish community, with a significant community of Polish immigrants who arrived mostly in the early- to mid-twentieth century. The community is home to two Catholic churches: All Saints Church, designed by Edwin Forrest Durang, built in 1889; and Saint John Cantius Church, built some time after 1892 in Polish Cathedral style. Boundaries The historic boundaries of the former borough of Bridesburg were the original course of Frankford Creek around the south and west, the Delaware River to the southeast, and Port Richmond to the southwest, along a border at Pike Street near Wheatsheaf Lane. Torresdale Avenue is the border to the western edge of the neighborhood that borders Frankford. Adjacent neighborhoods are Wissinoming to the northeast, Whitehall to the north, Frankford to the northwest, and Port Richmond to the southwe ...

Semi-automatic Rifle
A semi-automatic rifle is an autoloading rifle that fires a single cartridge with each pull of the trigger, and uses part of the fired cartridge's energy to eject the case and load another cartridge into the chamber. For comparison, a bolt-action rifle requires the user to cycle the bolt manually before they can fire a second time, and a fully automatic rifle fires continuously until the trigger is released. History The first design of a recoil-operated semi-automatic rifle is attributed to Ferdinand Mannlicher, who unveiled the design in 1885 based on work begun in 1883. Other non-gas operated semi-automatic models were the Model 85 and Mannlicher Models 91, 93 and 95 rifles. The designs were deeply flawed and never made past the conceptual/prototype stage due to issues inherent to the black powder used in their cartridges (based around the Austrian 11×58mmR M/77), such as insufficient velocity and excessive fouling; automatic firearms would only become feasible after smoke ...

Falling-block Action
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 lowered 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 which rely on lugs to lock the breech). This type of action is used in heavy artillery as well as small arms. An additional advantage is the unobstructed loading path, which imposes no limit on cartridge length; this was signif ...

Break Action
Break action is a type of firearm action in which the barrel or barrels are hinged much like a door and rotate perpendicularly to the bore axis to expose the breech and allow loading and unloading of cartridges. A separate operation may be required for the cocking of a hammer to fire the new round. There are many types of break-action firearms; break actions are universal in double-barrelled shotguns, double-barrelled rifles, combination guns, and are also common in single shot pistols (especially derringers), rifles, shotguns, and can also be found in flare guns, grenade launchers, air guns, and some older revolver designs. They are also known as hinge-action, break-open, break-barrel, break-top, or, on old revolvers, top-break actions. Description Break action The first break-action revolver was patented in France and Britain at the end of December in 1858 by Devisme. A substantial hinge pin joins the two parts of the rifle or shotgun; the stock with its firing mechanism and ...

Pump Action
Pump action or slide action is a repeating firearm action that is operated manually by moving a sliding handguard on the gun's forestock. When shooting, the sliding forend is pulled rearward to eject any expended cartridge and typically to cock the hammer/ striker, and then pushed forward to load (''chamber'') a new cartridge into the chamber. Most pump-action firearms use an integral tubular magazine, although some do use detachable box magazines. Pump-action is typically associated with shotguns, although it has been used in rifles and other firearms as well. Because the forend is manipulated usually with the support hand, a pump-action gun is much faster than a bolt-action and somewhat faster than a lever-action, as it does not require the trigger hand to be removed from the trigger while reloading. Also because the action is cycled in a linear fashion, it creates less torque that can tilt and throw the gun off aim when repeat-firing rapidly. History The first slide actio ...

Lever Action
The toggle-link action used in the iconic Winchester Model 1873 rifle, one of the most famous lever-action firearms Lever-action is a type of action for repeating firearms that uses a manually operated cocking handle located around the trigger guard area (often incorporating it) that pivots forward to move the bolt via internal linkages, which will feed and extract cartridges into and out of the chamber, and cock the firing pin mechanism. This contrasts to other type of repeating actions such as the bolt-action, pump-action, semi-automatic, or automatic/selective-fire actions. A firearm using this operating mechanism is colloquially referred to as a levergun. Most lever-action firearms are rifles, but some lever-action shotguns and a few pistols have been made. The Winchester Model 1873 rifle is one of the most famous lever-action firearms, but many manufacturers (notably Henry and Marlin) also produce lever-action rifles. Even Colt's Mfg. Co. produced the 6403 lever-action C ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bolt Action
Bolt-action is a type of manual firearm action that is operated by ''directly'' manipulating the bolt via a bolt handle, which is most commonly placed on the right-hand side of the weapon (as most users are right-handed). Most bolt-action firearms use a rotating bolt design, where the handle must first be rotated upward to unlock the bolt from the receiver, then pulled back to open the breech and allowing any spent cartridge case to be extracted and ejected. This also cocks the striker within the bolt (either on opening or closing of the bolt depending on the gun design) and engages it against the sear. When the bolt is returned to the forward position, a new cartridge (if available) is pushed out of the magazine and into the barrel chamber, and finally the breech is closed tight by rotating the handle down so the bolt head relocks on the receiver. Bolt-action firearms are generally repeating firearms, but some single-shot breechloaders also use bolt-action design as ...
