Generally speaking, we generally believe that Americans like to play with shotguns best. However, a particularly interesting shotgun developed by the Germans a hundred years ago, semi-automatic and round-fired, is also the automatic principle of barrel forward impact, which is very rare. This gun is called belk shotgun, which is made by Dusseldorf Hunting Weapons Company.
The patent was applied for by 1898, but maybe the technology was not up to standard or there was a problem with reliability at that time, so it was actually put into production by 1920s. Moreover, automatic loading technology was still being explored at the end of 19, so the structure of this Becker shotgun was particularly creative. There is a bullet hole similar to a revolver, with a capacity of 5 rounds of ammunition, and each empty place has an independent bullet sleeve.
Belk shotgun is a weapon which adopts the principle of automatic muzzle projection. In order to realize the weapon's shell withdrawal/recoil-reentry/ammunition supply, the form of gun recoil is generally adopted. Air-guided weapons make lightning retreat The gun barrel recoil weapon is to retreat the gun barrel together first, and then retreat the gun barrel.
The forward movement of the barrel means that the gun is not moving, and when the gun is fired, the force is pushed forward, and the action of shell withdrawal-reentry is completed again. Becker's shotgun uses a similar principle to Schwarzenegger's, but the attack method is quite different. Schwarzenegger is like hitting the primer of a bullet directly with a firing pin, while Becker drives the firing pin to primer through the expansion of the machine under the recoil of the muzzle.
Becker needs to pull the barrel forward more than 20 mm when loading the gun. When the trigger is pulled, the barrel will be pulled back by the spring. At this time, the shell behind the barrel and in the bomb nest are closed, and another set of expander connected with the barrel drives the firing pin to hit the primer. When the bullet is fired, the barrel is pushed forward by the pressure of gunpowder gas, and the trigger is pulled, while the bullet wheel rotates clockwise, and the next bullet aims at the barrel.
Although this mechanism is complicated, it effectively avoids the blazing gap problem of the rotating gun. In addition, there is an interesting projectile ejection system. On Becker's right, there is a cabin for loading/ejecting shells, about 2 o'clock. When the bullet at 12 o'clock is fired, a part of gunpowder gas will be introduced into the bullet hole at 2 o'clock, and then the cartridge case previously fired at this position will be blown out.
1 The bomb won't explode when it is launched, because the place at two o'clock is closed at this time. If you make a magazine, if there is a bullet, just hit the one that didn't hit. If there are no bullets, gunpowder gas will come out from here and paste your face. 1 When the bullet is finished, the bullet wheel rotates, and No.2 is ready to go, and No.2 is launched. Introduce gas into silo 1, blow out empty shells, and so on. What about the last round of shell 5?
The Germans designed a shell-withdrawing rod at this position, which can be pulled back to withdraw the shell, similar to the shell-withdrawing rod of the early revolver pistol. This semi-automatic wheel shotgun is innovative, but the factory has produced more than 100 guns, because the structure is too complicated and the processing technology is high, only Germans can think of it. However, if this kind of gun had been produced earlier in World War I, we might have seen Germany and the United States killing each other with spray guns in the trenches.
