Fittipaldi Machine Gun
The Fittipaldi machine gun is a recoil-operated machine gun designed by Rafael Fittipaldi (an Italian immigrant to Argentina) and patented as USPTO number 1,099,245, of June 9, 1914. Description The Fittipaldi machine gun uses the barrel of the Argentinian Mauser Model 1891 rifle as well as its bolt, the latter adapted for rectilinear action. It was fed by a non-disintegrating belt and used a traditional tripod as mount. A water jacket covered the entire length of its barrel, giving it an external appearance similar to the Lewis Gun. History The Fittipaldi machine gun was not adopted by the Argentine Army The Argentine Army ( es, Ejército Argentino, EA) is the land force branch of the Armed Forces of the Argentine Republic and the senior military service of Argentina. Under the Argentine Constitution, the president of Argentina is the commander- .... Little is known about its history or performance, including why it was not adopted.

Buenos Aires
Buenos Aires ( or ; ), officially the Autonomous City of Buenos Aires ( es, link=no, Ciudad Autónoma de Buenos Aires), is the capital and primate city of Argentina. The city is located on the western shore of the Río de la Plata, on South America's southeastern coast. "Buenos Aires" can be translated as "fair winds" or "good airs", but the former was the meaning intended by the founders in the 16th century, by the use of the original name "Real de Nuestra Señora Santa María del Buen Ayre", named after the Madonna of Bonaria in Sardinia, Italy. Buenos Aires is classified as an alpha global city, according to the Globalization and World Cities Research Network (GaWC) 2020 ranking. The city of Buenos Aires is neither part of Buenos Aires Province nor the Province's capital; rather, it is an autonomous district. In 1880, after decades of political infighting, Buenos Aires was federalized and removed from Buenos Aires Province. The city limits were enlarged to include t ...

Recoil-operated
Recoil operation is an operating mechanism used to implement locked breech, autoloading firearms. Recoil operated firearms use the energy of recoil to cycle the action, as opposed to gas operation or blowback operation using the pressure of the propellant gas. The earliest mention of recoil used to assist the loading of firearms is sometimes claimed to be in 1663 when an Englishman called Palmer proposed to employ either it or gases tapped along a barrel to do so. However no one has been able to verify this claim in recent times, although there is another automatic gun that dates from the same year, but its type and method of operation are unknown. Recoil-operation, if it was invented in 1663, would then lay dormant until the 19th century, when a number of inventors started to patent designs featuring recoil operation; this was due to the fact that the integrated disposable cartridge (both bullet and propellant in one easily interchangeable unit) made these designs viable.

Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USPTO
The United States Patent and Trademark Office (USPTO) is an agency in the U.S. Department of Commerce that serves as the national patent office and trademark registration authority for the United States. The USPTO's headquarters are in Alexandria, Virginia, after a 2005 move from the Crystal City area of neighboring Arlington, Virginia. The USPTO is "unique among federal agencies because it operates solely on fees collected by its users, and not on taxpayer dollars". Its "operating structure is like a business in that it receives requests for services—applications for patents and trademark registrations—and charges fees projected to cover the cost of performing the services tprovide . The Office is headed by the Under Secretary of Commerce for Intellectual Property and Director of the United States Patent and Trademark Office, a position last held by Andrei Iancu until he left office on January 20, 2021.

Mauser Model 1889
The Mauser Model 1889 is a bolt-action rifle of Belgian origin. It became known as the 1889 Belgian Mauser, 1891 Argentine Mauser, and 1890 Turkish Mauser. History After the Mauser brothers finished work on the Model 71/84 in 1880, the design team set out to create a small caliber repeater that used smokeless powder. Because of setbacks brought on by Wilhelm Mauser's death, they failed to have the design completed by 1882, and the German Rifle Test Commission (Gewehr-Prüfungskommission) was formed. The commission preferred to create their own design. Paul Mauser created two different variations of the same rifle, one with a stock strengthened with a barrel shroud and a traditional design following the layout of the 71 series in hope he might be able to overturn the commission's decision, or at least sell his design to the Kingdom of Bavaria, which adopted its own arms. The two rifles became known as the 89 Belgian (with a barrel shroud) and the 91 Argentine (with a 71 layout) M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Belt-fed systems minimize the proportional weight of the ammunition apparatus to the entire weapon system, and allow high rates of continuous fire without needing frequent magazine changes. The capacity of belts and associated belt containers is typically a function of weight and bulk, and their size is limited by caliber and the combined portability of the weapon and ammunition. The most common ammo capacity typically carried on a man-portable weapon system vary from 50 to 300 rounds. Variants Feed strip 8mm Lebel feed strip on an M1914 ...

Tripod
A tripod is a portable three-legged frame or stand, used as a platform for supporting the weight and maintaining the stability of some other object. The three-legged (triangular stance) design provides good stability against gravitational loads as well as horizontal shear forces, and better leverage for resisting tipping over due to lateral forces can be achieved by spreading the legs away from the vertical centre. Variations with one, two, and four legs are termed ''monopod'', ''bipod'', and ''quadripod'' (similar to a table). Etymology First attested in English in the early 17th century, the word ''tripod'' comes via Latin ''tripodis'' (GEN of ''tripus''), which is the romanization of Greek (''tripous''), "three-footed" (GEN , ''tripodos''), ultimately from (''tri-''), "three times" (from , ''tria'', "three") + (''pous''), "foot". The earliest attested form of the word is the Mycenaean Greek , ''ti-ri-po'', written in Linear B syllabic script. Cultural use Many cultur ...

Water Jacket
A water jacket is a water-filled casing surrounding a device, typically a metal sheath having intake and outlet vents to allow water to be pumped through and circulated. The flow of water to an external heating or cooling device allows precise temperature control of the device. Applications Water jackets are often used in watercooling. They are also used in laboratory glassware: Liebig, Graham, and Allihn condensers. Water jackets were used to cool the barrels of machine guns until several years after the First World War, but modern machine guns are air-cooled to conserve weight and hence increase portability. In a reciprocating piston internal combustion engine the water jacket is a series of holes either cast or bored through the main engine block and connected by inlet and outlet valves to a radiator. Equipment such as tissue culture Tissue culture is the growth of tissues or cells in an artificial medium separate from the parent organism. This technique is also called mi ...

Argentine Army
The Argentine Army ( es, Ejército Argentino, EA) is the land force branch of the Armed Forces of the Argentine Republic and the senior military service of Argentina. Under the Argentine Constitution, the president of Argentina is the commander-in-chief of the Armed Forces, exercising his or her command authority through the Minister of Defense. The Army's official foundation date is May 29, 1810 (celebrated in Argentina as the ''Army Day''), four days after the Spanish colonial administration in Buenos Aires was overthrown. The new national army was formed out of several pre-existing colonial militia units and locally manned regiments; most notably the Infantry Regiment "Patricios", which to this date is still an active unit. , the active element of the Argentine Army numbered some 70,600 military personnel. History Several armed expeditions were sent to the Upper Peru (now Bolivia), Paraguay, Uruguay and Chile to fight Spanish forces and secure Argentina's newly gain ...

Paz Palace
The Paz Palace is a former mansion in Buenos Aires, Argentina, housing the Military Officers' Association, a social club maintained by the Argentine military. Overview One of Buenos Aires' most traditional social clubs, the Military Officers' Association was founded in 1881 by Nicolás Levalle, a decorated officer in the Argentine Army who believed such a facility could help mitigate tensions among the officer corps from Argentina's then-fractious provinces. The club relocated to a palace facing San Martín Plaza in 1938. The building was designed by French architect Louis Sortais and built between 1902 and 1914 at the behest of José C. Paz, the proprietor of the city's then-second most-circulated newspaper, ''La Prensa''. Built entirely with material imported for the purpose from France, the palace stands near the eastern end of Santa Fe Avenue, in the Retiro section of Buenos Aires. The association established a number of cultural entities. The Officers' Cultural Foundat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
