The US Army wanted to be able to manufacture this general-purpose gun because it was technically advanced and much easier to make than the World War II US light and medium machine guns and it was decided to convert several MG 42s to fire .30-06 Springfield M2 ball ammunition. The MG 42V had some influence in the post-war development of roller-delayed blowback system, as employed in issued CETME, SIG and Heckler & Koch small arms. [16] Experiments with these were underway before the end of the war, and again the LVG company seems to have been involved: a British intelligence report from 25 June 1918 mentions an LVG two-seater fitted with such a gear that was brought down in the British lines. Seven shells fired. Fokker's initial answer to this was the fitting of extra "followers" to the Stangensteuerung's large cam wheel, to (theoretically) produce the "ripple" salvo necessary to ensure that the guns were aimed at the same point on the propeller disc. [62] The M53 was known under the nickname (arac).[63]. The standard MG 42 bolt weight for a 1,500 rounds per minute cyclic rate of fire is 505g (17.81oz).[37]. The (slower) rapid firing rate used in emergency/final defensive line situations of the MG 42 was up to 500 rounds per minute. [5] The M3 fired an M82 APC shot with a muzzle velocity of 2,650ft/s (810m/s). [19] In trials in 1894, the machine lifted and was prevented from rising by the outriggers. The first victory using a synchronized gun-equipped fighter is now believed to have occurred on 1 July 1915 when Leutnant Kurt Wintgens of Feldflieger Abteilung 6b, flying the Parabellum-armed Fokker M.5K/MG aircraft "E.5/15", forced down a French Morane-Saulnier Type L east of Lunville.[38]. [33], Hiram Maxim married his first wife, the English-born Jane Budden, on 11 May 1867 in Boston, Massachusetts. The Gurttrommel belt container was commonly used until the end of World War II, with the MG 42 and the earlier MG 34. Because the standard fifteen-and-a-half foot long M3 90mm main tank gun proved incapable of penetrating the heaviest frontal armor of the heaviest German tanks such as the Tiger II tank and the rarer Jagdtiger tank destroyer variant, a number of improved versions of the M3 were developed, including the T14 which included a standard muzzle brake and the T15 series. With the SCR-584, direction and range information was sent directly to the Bell Labs M3 gun data computer, and M9 director, which could direct and lay the guns automatically, all the crews had to do was load the guns. Wragg, D.; "Flight Before Flying", Osprey (1974). [12] As the propeller revolved, a series of "firing impulses" was transmitted to the gun, effectively "pulling the trigger", to fire a single shot. One AAA M1A1 at Fort Sill, Oklahoma, US Army Air Defense Artillery Museum. This carbon rich surface is then heat treated resulting in a thin, very hard surface layer with a tough, malleable core. The new design seemed so much better than developments of the older three-inch that work on the three-inch T9 was canceled in 1938, just as it became production-ready. While some gunsmiths are general practitioners in this trade, some of the more important specializations are: Builds guns to customer's specification, from raw materials and shelf parts. A two-bladed propeller would therefore obstruct the gun six times every firing cycle of the gun, a four-bladed one twelve times. Courtney rather pungently remarks that "there was no particular secret to protect". [36], The cyclic firing rate of the MG 42 can be altered by installing different bolts and return springs. While the basic principle of the new gear remained unchanged: virtually all the components had been redesigned, and it was no longer officially referred to as the "Nelson" gear. One AAA M2A2 at Fort Sill, Oklahoma, US Army Air Defense Artillery Museum, One AAA M1A1 at Fort Sill, Oklahoma, 31st ADA Brigade, One AAA M1A1 at US Veterans Memorial Museum, Huntsville, AL, One AAA M1A1 at Halifax, Nova Scotia, Royal Artillery Park. The early Schwarzlose gun had a synchronized rate of 360 rounds per minute with this gear this was later boosted to 380 rounds with the MG16 model. ISBN978-1-4402-2651-9. [8] [16] A very similar problem could arise where the mass of a special round (such as an incendiary or explosive one) was different enough to produce a substantial difference in muzzle velocity. A 250-round Patronengurt 33 belt was also issued to machine guns installed in fixed emplacements such as bunkers. [27] In 1944, this was altered to six machine guns in three sections with two seven-man heavy machine gun squads per section as follows: The optimum operating crew of an MG 42 in its medium machine gun role was six men: the squad leader, the machine gunner who carried and fired the gun, the assistant gunner/loader who carried the tripod, and three riflemen who carried 1,800 rounds of ammunition between them, spare barrels, entrenching tools, and other items. Unfortunately, when the gear was fitted to types such as the Bristol Scout and the Sopwith 1 Strutter, which had rotary engines and their forward-firing machine gun in front of the cockpit, the long push rod linking the gear to the gun had to be mounted at an awkward angle, in which it was liable to twisting and deformation as well as expansion and contraction due to temperature changes. The development of the weapon was completed in 1974. [54], There were numerous other specialist mounts for the MG 42. Upon standardization of the M47 in 1951, the T119 was redesignated as the 90mm gun M36.[13]. Maxim held patents on numerous mechanical devices such as hair-curling irons, a mousetrap, and steam pumps.Maxim laid claim to inventing the lightbulb.. Maxim experimented with powered flight; Having the two guns firing simultaneously would obviously not have been a satisfactory arrangement. Enough guns were damaged and put out of action for repair or lost to warrant finding the cause and a solution. German Artillery of World War Two, Ian V. Hogg. gear was already in prospect. Although made of relatively inexpensive and simple parts, the prototypes proved to be considerably more rugged and resistant to jamming than the precisely machined and somewhat temperamental MG 34. In 1911, Maxim headed the newly formed Grahame-White, Blriot, and Maxim Company, founded with the two aviators and two hundred thousand pounds of capital. A mitrailleuse (French pronunciation: ; from French mitraille, "grapeshot") is a type of volley gun with barrels of rifle calibre that can fire either all rounds at once or in rapid succession. [44] Unlike the French and Italians, who were eventually able to acquire supplies of Vickers guns, the Austrians were unable to obtain sufficient quantities of "Spandaus" from their German allies and were forced to use the Schwarzlose in an application for which it was not really suited. The early mechanical synchronization gears turned out to be inefficient and unreliable, and full standardisation on the very satisfactory hydraulic "C.C." [58] Sir Hiram Stevens Maxim (5 February 1840 24 November 1916) was an American-British inventor best known as the creator of the first automatic machine gun, the Maxim gun. I wished to show that we were not all fools. )[citation needed] Hiram called himself a Protestant. [5], It has been pointed out that any mechanism that achieved the feat of firing between the whirling blades of a propeller without striking them could be described as "interrupting" the fire of the gun (to the extent that it no longer actually works as an automatic weapon at all), and also as "synchronizing", or "timing" its fire to coincide with the revolutions of the propeller.[6]. MG 42s were mounted in multiple-gun arrangements, particularly for low level anti-aircraft defence.[55]. These typically have highly sophisticated breech mechanisms, precise fitting, and are hand-engraved by artists specializing in this work.

Measure and correct head-space dimensions. In early 1942 the final model of the weapon was officially accepted, and manufacturing of the mass-production model began, as the MG 42, contracts going to Grofu, Mauser-Werke, Gustloff-Werke, Steyr and others. The only major changes from the gunner's perspective were dropping of the saddle-drum-magazine feed option, leaving the weapon to fire belted ammunition, or from a single 50-round drum-shaped Gurttrommel belt container fitted to the gun's receiver, and simplifying the weapon's open sights for aiming purposes. They were seen as rewarding the true marksman, as they involved less dependence on gun sight technology. The gun's shells had to punch through seven metres of reinforced concrete or one full metre of steel armour plate, from beyond the range of French artillery. [62] The first working C.C. Although sometimes defined as "an electronic version of a printed book", some e-books exist without a printed equivalent. [52], The first British synchronizer gear was built by the manufacturer of the machine-gun for which it was designed: it went into production in December 1915. ), intended modification (minimum barrel length? The increased speeds of the new monoplanes of the mid to late 1930s meant that the time available to deliver a sufficient weight of fire to bring down an enemy aircraft was greatly reduced. A mechanism to enable an automatic weapon to fire between the blades of a whirling propeller is usually called an interrupter or synchronizer gear. As in the MG 34, operation through the feed block is by a feed arm housed in the feed cover. [44], This article is about Hiram Stevens Maxim. The gun reached the Perekop Isthmus in early March 1942, where it was held until early April. News of the most highly skilled and talented gunsmiths typically spreads by word of mouth, based on the quality of their work. This design philosophy, common in Britain and France (and, after 1941, the United States) tended towards eliminating fuselage mounted guns altogether. Mounting guns in the fuselage also concentrated mass at the centre of gravity, thus improving the fighter's roll ability. Like the MG 42, the MG3 cyclic rates of fire can be altered by exchanging the standard weight (about 650g (22.93oz)) bolt used for the standard 1,1001,300 rounds per minute rate of fire for an extra weight (about 900g (31.75oz)) bolt for a reduced 800950 rounds per minute rate of fire. Polygonal rifling was an outgrowth of a cold-hammer forging process developed by German engineers before World War II. [8] Installation began in early May, and by 5 June the gun was ready to fire. Targets were to reduce, among other things, the cyclic rate of fire and weight and have more versatile sights and mount. [51] Ball actually had his Vickers gun removed altogether for a while, to save weight. By February 1943, US ordnance authorities published the first report on the MG 42, following testing of a captured gun. [10] After being criticised for applying his talents to quackery, he protested that "it will be seen that it is a very creditable thing to invent a killing machine, and nothing less than a disgrace to invent an apparatus to prevent human suffering". An effective "anti-bomber" fighter needed something more. [11], In practice it was found that it was necessary for the gun to be fired in semi-automatic mode. Significantly, early problems with the C.C. Different parts of the gear are color-coded as follows: Unsynchronized guns and the "deflector wedge" concept, Fokker's Synchronizer and other German gears. Ammunition boxes contained 250 rounds in five 50-round belts. Many early gears used an intricate and inherently fragile bell crank and push rod linkage that could easily jam or otherwise malfunction, especially when required to work at higher speeds than it had been designed for. [22], Whether directly inspired by Euler's original patent or not, the first inventor to patent a method of firing forward through a tractor propeller was the Swiss engineer Franz Schneider, formerly with Nieuport, but by then working for the LVG Company in Germany. These would eventually find their way to Czechoslovakia and Yugoslavia. [11], The gun was then dismantled and moved to the northern part of the eastern front, where an attack was planned on Leningrad. Report AD301343 An Analytical Study of Data on Armor Penetration by Tank-Fired Kinetic Energy Projectiles. [30] Garros himself and Jules Hue (his personal mechanic) are sometimes credited with testing and perfecting the "deflectors". The 90 mm gun M1/M2/M3 was an American heavy anti-aircraft and anti-tank gun, playing a role similar to the German 8.8cm Flak 18.. The T24 was chambered for the .30-06 Springfield cartridge. After his early synchronization experiments failed, Saulnier pursued a method trusting rather less to statistics and luck by developing armoured propeller blades that would resist damage. The Lafette could be set up in a prone, kneeling or high position. From the beginnings of practical flight, possible military uses for aircraft were considered, although not all writers came to positive conclusions on the subject. Officially known as the Systme de Synchronisation pour Vickers Type II (moteurs fixes) the Birkigt gear was later adapted to control two guns, and remained in use in French service up to the time of the Second World War. As it is recoil-operated and fired from an open bolt, the weapon must be manually charged with the side-mounted charging handle. The case was eventually dropped, being settled for under $1,000 (the original amount asked for was $25,000), and Maxim put behind him the near public humiliation the case caused. 31: Puppy Love (4.64) Brit arranges the Charity Carwash at the Firehouse. Heavy bolts also were used along with stiffer return springs. "The holding will call into question many other regulations that protect consumers with respect to credit cards, bank accounts, mortgage loans, debt collection, credit reports, and identity theft," tweeted Chris Peterson, a former enforcement attorney at the CFPB who is now a law The M3 gun was used on the M36 tank destroyer, and the T26 (later, M26) Pershing tank. 31: Puppy Love (4.64) Brit arranges the Charity Carwash at the Firehouse. "The holding will call into question many other regulations that protect consumers with respect to credit cards, bank accounts, mortgage loans, debt collection, credit reports, and identity theft," tweeted Chris Peterson, a former enforcement attorney at the CFPB who is now a law [7] They charged seven million Reichsmark (approximately 24 million USD in 2015) for the second gun, Dora, named after the senior engineer's wife. The MG 42 is a 7.9257mm Mauser, air-cooled, belt fed, open bolt, recoil-operated machine gun with a quick change barrel. The speed of the propeller, and thus the distance that it travelled between the firing of the gun and the arrival of the bullet at the propeller disc, varied as the rate of engine revolutions changed. Although sometimes defined as "an electronic version of a printed book", some e-books exist without a printed equivalent. It proved less of a problem than was at first supposed once it was realized that it was the aircraft that was aimed rather than the gun itself. Attempts to incrementally improve the basic MG 34 design failed. Chloe asks Brit to test her Man's loyalty. We apologize for any inconvenience and are here to help you find similar resources. In the United States, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is the primary federal agency overseeing all legitimate businesses that deal with firearms, with the exception of firearms made before January 1, 1899 or muzzle loading firearms. A single firing lever engaged the gear and fired the gun in one action, rather than the gear having to be "turned on" and then fired, as with some earlier gears. The train carrying the gun was of 25 cars, a total length of 1.5 kilometres (0.9mi). There were many practical problems, mostly arising from the inherently imprecise nature of an automatic gun's firing, the great (and varying) velocity of the blades of a spinning propeller, and the very high speed at which any gear synchronizing the two had to operate. The Lafette 42 weighed 20.5kg (45.2lb) on its own and was a simplified version of the Lafette 34 used for the MG 34, as the MG 42 could be operated more easily from a Lafette and featured no semi-automatic firing mode. Thus aerial combat was by no means entirely unanticipated, and the machine gun was from the first seen as the most likely weapon to be used. Originally, Maxim had intended to build only two, but a lengthy breakdown on the original Earl's Court ride forced him to build more to make the venture profitable. [59] This gear was specifically intended to overcome the faults of earlier gears. '"[11], As a child, Maxim had been knocked over by a rifle's recoil, and this inspired him to use that recoil force to automatically operate a gun. Entering production in 1942, it was intended to supplement and replace the earlier MG 34, which was more expensive and took much longer to produce, but both weapons were produced until the end of World War II. The T119 was backwards compatible with the ammunition used on the M3A1. [28] This eventually proved unsatisfactory, as the oil pump's mechanical drive spindle was insufficiently robust to take the extra load. They ruled that the results of sustained fire were disappointing and that the expenditure of ammunition involved was "intolerable. Test-fire guns with conventional loads to ensure proper operation. [Note 3] Both of these measures impinged on the question of synchronization. The very best and most talented gunsmiths command premium prices for their services, and may have waiting lists booked for several years in advance. p 233. A limited run of about 1,500 of further improved MG 39/41 pre mass-production model guns, was completed in 1941 and by the end of 1941 tested in combat trials. [5], For carrying and protecting spare barrel units, consisting of a barrel and its locking piece, the Laufschtzer 42 (barrel protector) was used as a field accessory. Both these terms are more or less misleading, at least insofar as explaining what happens when the gear functions. Non-observance of this technical limitation renders the barrel prematurely unusable. ), quantity of firearms (how many per week? In fact it became the standard synchronizer for the Luftstreitkrfte for the remainder of the war,[41] although experiments to find an even more reliable gear continued. [41][42][43] Many of the world's foremost art museums have highly decorated firearms in their collections because of the high artistic merit and craftsmanship of their engraved, chiseled, and carved decoration. Italy has a hunting tradition dating back several centuries. [48], This gear was designed by Oberleutnant Eduard Zaparka. 512). In this film, the attacking Coyote reduces his propeller to splinters after numerous bullets strike. [31] In the following year, Queen Victoria bestowed a knighthood on him. [9], Maxim, a longtime sufferer of bronchitis, patented and manufactured a pocket menthol inhaler and a larger "Pipe of Peace", a steam inhaler using pine vapour, that he claimed could relieve asthma, tinnitus, hay fever and catarrh. [6], On 1 April 1915 Garros shot down his first German aircraft, killing both the crew. The main problem is that it assumes Garros was flying the same machine that Saulnier had used for his earlier tests! The 90mm gun was the US Army's primary heavy anti-aircraft gun from just prior to the opening of World War II into 1946, complemented by small numbers of the much larger 120 mm M1 gun. The British men in the business of colonizing the North American continent were so sure they owned whatever land they land on (yes, thats from Pocahontas), they established new colonies by simply drawing lines on a map. [10] The Grofu company had no earlier experience in weapons manufacture, specializing in pressed and stamped steel components (the company's staple product was sheet metal lanterns). The final design, which appeared in 1950, was in most respects still similar to the MG 42, although many components were produced by machining instead of stamping, which increased the weight, the stability and the production costs of the machine gun. E.g., being unsure whether the real distance was 2,000 or 2,300m (2,187 or 2,515yd), the gunner could make the mount do an automatic sweep between the elevations for 1,900 to 2,400m (2,078 to 2,625yd) and back. [40] So Goes My Love, a film loosely based on these memoirs and starring Don Ameche and Myrna Loy, was released in 1946. Firearms possession is highly regulated by the police, and most hunters own only one long gun and perhaps a single pistol. Hudson had success in the States, which caused jealousy from Hiram (he lamented having a "double" of himself running around in the States). Towed anti-aircraft gun. M3 gun with muzzle brake, used on M46 Patton and early versions of the M48 Patton tanks and refurbished M36 tank destroyers during the Korean War. [51], Another unique feature of German World War II machine guns was the Tiefenfeuerautomat feature on the Lafette 42 and Lafette 34 tripods. [39] Hiram Percy later wrote a biography of his father titled A Genius in the Family, containing about 60 anecdotes of Hiram Percy's experiences with his father throughout his early life (until about age 12). Their improved development of the Maxim gun design, the Vickers machine gun, after Maxim's resignation from the board in 1911 on his 71st birthday, was the standard British machine gun for many years. The roller-locking system inherent problem was solved after World War II by developing and adding bolt-bounce preventing bolt catches to the action.
