Definitions

  • the invention relates to a cartridge magazine and a cartridge feed device for an elevatable firearm, in particular for a multi-barrel cannon.
  • a known ammunition magazine of this type there are two ammunition stores. There are a number of cartridges in each ammunition store. With the aid of a device for merging the two rows of cartridges, the two rows of cartridges - combined into a single row - can be fed to the weapon.
  • this known ammunition magazine is arranged in a stationary manner and does not follow the movement of the weapon around the azimuth axis and around the elevation axis. Therefore, a flexible feed channel is required between the ammunition magazine and the movable firearm.
  • the object which is to be achieved with the present invention is to create a cartridge magazine and a cartridge feed device which does not have the disadvantages of the known magazines and devices; which is particularly suitable for firearms of high cadence, and with which great acceleration forces at the start of a series fire to accelerate the ammunition supply are avoided as far as possible.
  • the cartridge magazine and the cartridge supply device with which this object is achieved is characterized in that the cartridge magazine consists of three ammunition containers which are rigidly attached to the firearm and thus participate in the pivoting movement of the firearm about the azimuth axis and the elevation axis, that a first conveyor device feeds the cartridges from the middle of the three ammunition containers to the firearm, so that a second conveyor alternately feeds a cartridge from one and then from the other of the outer two ammunition containers to the middle ammunition container.
  • the elevatable firearm 10 is mounted on a turret 13 with the aid of a turntable 11 about a vertical azimuth axis 12.
  • Two supports or supports 14 are fastened on the turntable 11, of which only one support 14 is shown in FIG.
  • the firearm 10 is mounted pivotably about a horizontal elevation axis 15 between these supports 14 (FIG. 3).
  • the firearm 10 has a bundle of seven weapon tubes 16, which together form a rotor 17 which is rotatably mounted in a weapon housing 18, see also FIG. 3.
  • Firearm 10 is not the subject of the present invention and is only to be described here to the extent necessary to understand the invention.
  • the cartridge magazine 19 (FIG. 5), which is composed of three ammunition containers 20, 21 and 22, is rigidly attached to the firearm 10 and can therefore be pivoted about the elevation axis 15 with the firearm 10.
  • the middle ammunition container 21 differs from the two outer ammunition containers 20 and 22 essentially in that it has a first conveying device 23 with which the cartridges 24 can be fed from this middle ammunition container 21 to the firearm 10. With the aid of this first conveyor device 23, the cartridges 24 can be rotated through 90 °.
  • the cartridges 24 are arranged in the cartridge magazine 19 parallel to the elevation axis and must be fed to the firearm 10 parallel to the weapon barrel axis.
  • This conveyor device 23 contains an endless conveyor chain 25 with which the cartridges 24 can be fed from the container 21 of the weapon 10 on the one hand and on the other hand the empty cartridge cases 37 can be returned from the firearm 10 into the cartridge magazine 19.
  • the cartridges 24 are fed to the middle ammunition container 21 with the aid of a second conveyor device 27 - with which the cartridges 24 are alternately removed from one and from the other of the two outer ammunition containers 20, 22 - as in particular can be seen from Figure 4.
  • This conveyor device 27 contains an endless conveyor chain 28 with two rows of cups 29 and 30 for receiving the cartridges 24.
  • a cup 30 also protrudes with its half length between two cups 29 of the conveyor chain 28.
  • the cartridges 24 can be moved in this cup 29 and 30 from the outer end of the cup 29,30 against the inner end of the cup 29,30. 4, the cartridges 24 pass from the two outer ammunition containers 20, 22 into the middle ammunition container 21.
  • the cartridges 24 are located in the two outer ammunition containers 20, 22 each in an endless storage and conveyor chain 31 and 32, respectively.
  • the cartridges 24 get out of the storage and conveyor chain 31 of the one ammunition container 20 with the aid of a first one Transfer device 33 into the cup 29 of the conveyor chain 28 and from the second storage and conveyor chain 32 of the other outer ammunition container 22, the cartridges 24 get into the cup 30 of the conveyor chain 28 with the aid of a second - but not shown in the drawing - corresponding transfer device this conveyor chain 28, the cartridges 24 arrive with the aid of a third transfer device 34 into an endless storage and conveyor chain 35 (FIG. 1) in the middle ammunition container 21.
  • a fourth transfer device 36 With the aid of a fourth transfer device 36, the cartridges 24 emerge from the endless storage and conveyor chain 35 the mentioned first conveyor 23 and are from the endless conveyor chain 25 of the firearm 10 supplied.
  • the described transfer devices 33, 34 and 35 also serve to transport the empty cartridge cases 37 back.
  • the various transfer devices 33, 34 and 36 just described differ substantially from one another.
  • cartridges 24 from the endless storage and conveyor chain 31 of the outer ammunition container 20 are fed exclusively to the cups 29 of the endless conveyor chain 28 of the conveyor device 27.
  • the second transfer device of exactly the same design, not shown cartridges 24 from the endless storage and conveyor chain 32 of the outer ammunition container 22 are exclusively the cups 30 of the endless conveyor chain 28 fed to the conveyor device 27.
  • the endless conveyor chain 28 must move twice as fast as the two storage and conveyor chains 31 and 32 of the two outer ammunition containers 20 and 22.
  • the first transfer device 33 and the second transfer device (not shown) must therefore be able to Accelerate cartridges 24 to a higher speed.
  • both the cartridges 24 from the cups 29 and from the cups 30 of the endless conveyor chain 28 of the conveyor device 27 are transferred to the endless storage and conveyor chain of the middle ammunition container 21.
  • This third transfer device therefore does not have to accelerate or decelerate the cartridges 24.
  • the fourth transfer device 36 With this fourth transfer device 36, all cartridges 24 from the endless storage and conveyor chain 35 of the middle ammunition container 21 are transferred to the endless conveyor chain 25 of the first conveyor device 23.
  • the cartridges 24 generally do not have to be accelerated or decelerated.
  • the structure of these various transfer devices is assumed to be known and is therefore not described in detail here (see US Pat. No. 4,658,701).
  • the firearm 10 is driven by a motor 40 via a gear 41.
  • this engine 40 can also the three endless storage and conveyor chains 31, 32 and 35 are driven in the three ammunition containers 20, 21 and 22.
  • the gears required for this are not shown in the drawing.
  • the two conveying devices 23 and 27 are driven by the motor 40 via gears (not shown).
