Abstract

A revolver machine gun for firing disc-type projectiles, which are caused to rotate during firing by means of an eccentric centre of gravity, and thus achieve a boomerang effect. The ammunition is located in a magazine underneath the drum, from which the rounds are emitted successively, from four chambers. As a result of the rotation, the disc-type projectiles achieve a stable flight path over a long range and thus a high hit probability while, on the other hand, targets behind an obstruction can be fired at from the rear, by using the boomerang effect.

Description

I. The object of the invention belongs to the smooth tube Firearms and serves to increase the fire strength of the shooter.

The aim of the invention is to extend the Functional possibilities by using a new one Firearm type for sleeveless cartridges of rectangular cross-section with a pressed-in disk floor, the center of gravity is shifted.

The disk boom "boomerang" is after with the heavy pole pressed into the cartridge at the top. As a result, the projectile at Launch a rotating movement from the bottom up or against awarded clockwise. The floor is vertical attached and when shooting with a steep exit angle it even flies over obstacles (walls, buildings, tanks, etc.) and hits the target from behind, i.e. H. it has one backward force, similar to that of a boomerang. At flat shot angle and calculated distance becomes the target hit directly.

Test shooting on foam polystyrene plates showed that a vertically attached with rotary movements from bottom to top or counter-clockwise shot disk itself after penetrating the foam polystyrene plate from the top to turns below and comes out on the back.

The revolver machine gun has a barrel 1 , a 4-chamber drum 2 , the lock 3 , which is connected to the gas pressure piston 5 by means of the piston rod 4 . The lock spring 6 is attached to the piston rod 4 . The firing pin 7 and a nose 8 are located on the lock 3 .

A device for rotating the drum 9 is attached to the rifle body. Under the lock 3 , Fig. No. 2, the cartridge feeder is attached, which feeds the cartridges into the drum 10 . This device is provided with the spring 11 . The drum is rotated with the help of the toothed disk 12 . The magazine 13 is inserted from below. There is the trigger 14 , the trigger 15 and the lock handle 16th

II. The invention belongs to smooth-tube firearms for Disk projectiles. There are none from the sources accessible to us Analogs for smooth-tube revolver pistols for caseless rectangular cartridges with a pressed-in disk bullet known.

There are devices for shooting spherical and Disc bullets with smooth cylindrical tubes or curved tubes (for inertia rotations) for disk projectiles known. The disadvantage of such devices with otherwise good ones Hitting distances) is the instability of the rotary movements, Deviation from the trajectory as a result of the incorrect arrangement of the Storey focus when loading, loading difficulties when loading due to the end opening of the barrel, high inertia loads and the slow firing order.

The disadvantages listed in the present invention are locked out. There are also advantages over the drawn ones Pipes in which the projectile is shot down by high Energy expenditure is forced to rotate, thus high Temperatures generated and the pipe wears out faster.

The novelty of the present invention is also that the rectangular cartridge more crowded, the manufacture of the smooth tube barrel easier and air cooling provided is. In addition, the 4-drum chambers heat up less because they are put into operation one after the other. Beyond that the use of explosive, detonating and other projectiles possible.  

Fig. 2 shows the device for air cooling, in which the air duct 22 is connected to the air grooves on the drum. At the end there is a cylindrical drill hole that connects the cooling channel with the barrel. The vacuum generated by the gas ejection at the running end 23 draws the air out of the channel 22 through the line filter 25 and thus cools the drum.

The aim of the invention is to extend the Functional possibilities of the firearm as well as the development additional ways to create other analog Weapon types, e.g. B. artillery weapons u. Ä.

The goal is achieved in that the lock 3 is pulled backwards with the help of the handle 16 in the revolver machine gun, the cock 14 being cocked. With the help of the nose 17 , the lock also returns the device which feeds the cartridges from the magazine to the drum. The lock handle is released and the lock returns using the spring 6 . The loading device returns after the drum has been loaded under the action of the spring 11 . Then the lock 3 pushes the lever 19 forward by means of the nose 8 , which rotates the drum and aligns the cartridge with the barrel. The revolver machine gun is now ready to fire.

When fired, the powder gases act more heavily on the lighter half of the disk projectile 20 and force it to rotate about its own axis. The projectile is thrown out of the barrel and reaches five times the distance from a non-rotating projectile.

The powder gas then presses via the overflow opening 21 onto the gas pressure piston 5 and flows out of the opening 26 . The lock 3 works automatically and the entire cycle is repeated.

In the description of the invention according to point I, the Descriptions of the tap device, the switch from single on fire and other parts intentionally omitted because these have proven themselves well in already known types of firearms had and can be used unchanged.

Claims (3)

1. The revolver machine gun for target bullets is characterized by a smooth barrel through which a 4-chamber drum with air cooling sleeveless rectangular cartridges consisting of pressed powder and disc bullets pressed into it with eccentric shifted focus to be fired. 2. The disk projectiles are characterized in that they with the heavy pole up in the caseless cartridges are pressed in, so that when they are shot down by the Powder gas pressure a rotary movement from bottom to top, or counter-clockwise. 3. The loading device of the revolver machine gun is characterized in that the drum is not a magazine, but serves as a cartridge chamber for firing the projectiles, due to the presence of 4 chambers only every 4th shot from the same chamber is fired what the existing air cooling can work better. The castle of the revolver machine gun is with the sprung Gas pressure piston rigidly connected. The charger works after a single manual loading and tensioning automatically, that is, after each shot a new one Cartridge inserted from the magazine into the drum and this is rotated by 90 ° to the barrel with the next one Bring chamber in line.
