Definitions

  • a training cartridge for automatic firearms, in particular for machine guns, is known from US Pat. No. 1,817,273, which is to be regarded as the closest prior art.
  • This cartridge consists of a cartridge that holds the powder charge and a paper projectile.
  • Another floor in the form of a lead diabolo is cemented onto the top of the paper floor.
  • this bullet which seals the barrel better and is relatively heavy in relation to the paper bullet, the recoil is increased in order to simulate realistic shooting conditions for the shooter.
  • the accuracy is somewhat improved, since the lead bullet is deformed but not disassembled after the powder charge has been ignited.
  • EP-A3-0 158 408 discloses a reusable cartridge in which a compressed gas, in particular compressed air, can be stored under very high pressure.
  • the cartridge has a chamber for this.
  • a relatively complex valve mechanism is required, which is triggered by the firing pin of the hand weapon.
  • the projectile to be fired is connected to the front end of the cartridge by means of a conical form fit. In the case of sub-caliber projectiles, this form-fitting connection exists between the end of the cartridge and a holding means for the projectile.
  • the valve mechanism is released, the high-tension gas flows out of the cartridge behind the projectile and accelerates it through the barrel.
  • the object of the present invention is to use a cartridge for loading and firing diabolos in such a way that the diabolo is not damaged or even destroyed.
  • a cartridge for loading and firing diabolos having a gas-generating agent arranged in an ignition capsule as an energy source and an expansion chamber for expanding the gaseous agent formed during the ignition process between the ignition capsule and the front end of the cartridge, wherein the diabolo is inserted into the barrel by being pressed in by the cartridge, whereby a pre-calibration takes place and, after the cartridge has been inserted into the barrel and after the ignition capsule has been ignited, the gases which form during ignition enter the expansion chamber.
  • the size of the expansion chamber of the cartridge used depends on the particular circumstances; if necessary, it can be determined empirically. With certain requirements a volume of approximately 100 mm3 has proven to be expedient.
  • the following substances can be provided as gas-generating agents: picric acid, tricinate, tetrazene, barium nitrate, calcium silicide, lead azide and lead resorcinate.
  • baffle-like internals are arranged in the expansion chamber, which have a favorable effect on the gas pressure build-up on the diabolo.
  • the floor end of the cartridge used with a thin membrane is advantageous. Like. Covered in order to switch off any contaminants entering the expansion chamber from the outside and to make manipulations more difficult.
  • a predetermined breaking point can be provided on the cartridge, which responds immediately at a freely selectable maximum pressure. This predetermined breaking point is of great importance, if the amount of the gas-generating agent in the primer or the addition in the expansion chamber increases the output by manipulation.
  • the cartridge of a hand weapon for. B. an air rifle
  • 2 indicates the primer, which in the illustrated embodiment consists of a suitably deep-drawn bowl 3 made of metal, which gas generating agent 4 takes.
  • This gas-generating agent 4 which can be, for example, picric acid, tricinate, tetrazene, barium nitrate, calcium silicide, lead azide and lead resorcinate, is covered with a film 5 in order to prevent harmful environmental influences from the outset.
  • the primer capsule 2 is inserted into a sleeve 6, the component of which is an anvil 7, which is surrounded by a plurality of bores 8 which are concentric to it and through which the gaseous agent 4 formed during the ignition process passes.
  • an expansion chamber 10 is provided, in which, depending on its size, the gases entering through the bores 8 are expanded to such an extent that the diabolo 9 remains undamaged in all cases.
  • baffle-like internals are expediently provided in the expansion chamber 10.
  • a filter 11 is selected for this purpose, which retains any ash residues and the filling of high-energy substances, e.g. B. nitrocellulose powder prevented.
  • a filter 10 was dispensed with, the baffle-like internals being indicated by the reference number 14.
  • the end of the cartridge on the projectile side is covered with a thin membrane 13.
  • predetermined breaking points 15 are provided on the cartridge which, when a predetermined maximum pressure is exceeded, discharge the gases via corresponding channels in the barrel of the hand weapon.
  • the handgun is loaded and operated as follows: First of all, the breech 16 of the hand weapon is opened and the diabolo 9 is inserted into the barrel 17 by being pressed in with the cartridge 1, which results in a pre-calibration. Subsequently, the cartridge 1 is inserted into the barrel 17 as disclosed in FIGS. 1 and 2 of the drawing. By triggering the firing pin 18 and striking the primer 2, the gas-generating agent 4 is ignited, the gases thereby forming entering the expansion chamber 10 via the bores 8. As a result, the gases acting on the diabolo 9 are reduced to such an extent that damage or destruction thereof is avoided in all cases.
  • the anvil 7 is replaced by an insert 19 which has obliquely outwardly pointing arms which are firmly connected to the bowl 3 at their ends.
