Definitions

  • the invention relates to a cartridge with a shotgun barrel according to the preamble of claim 1.
  • a cartridge belongs to the prior art according to Article 54 (2) EPC.
  • DE-PS 3 241 149 shows a cartridge with a shotgun barrel and a lead head with a tip and a plug made of elastic material which is connected to the lead head via a plug-in connection which has a sleeve-shaped projection in the interior of the cylindrical lead head.
  • the lead head is assigned a plug made of elastic material with a cup-shaped part, on which a pin pointing in the weft direction is formed, which engages in the sleeve-shaped extension of the lead head.
  • a wedge ring is arranged concentrically to this pin and engages in a wedge-ring-shaped recess in the lead head.
  • the plug connection formed from these parts does not completely fill the projectile head to the extent that a gap remains free between the end face of the wedge ring and the pin on the one hand and the end face of the associated recesses in the lead head on the other hand in the loading position of the cartridge.
  • the invention is based on the idea of improving these known cartridges with a shotgun barrel so that regardless of the respective manufacturing-related inaccuracies of the parts forming the projectile, the center of gravity of the bullet always comes to the same place after the propellant has been ignited.
  • Characteristic a ensures that the connection between the pin (3a) on the one hand and the lead head (1) on the other hand is free of play before and therefore inevitably even after firing.
  • FIG. 1 denotes the lead head of the projectile, the cylindrical part of which is provided with ribs 2 which run obliquely to the longitudinal axis.
  • Figure 4 of the drawing shows a vertical section through a made of an elastic material, for. B. plastic, existing plug, which consists of an upper part 3, a rod-shaped central part 4 and a flat piston-like lower part 5.
  • the flat piston-like lower part 5 is connected to the rod-shaped central part 4 via a predetermined breaking point 6, the details of which are described below.
  • the upper part 3 of the plug has a cylindrical pin 3a which engages in a blind hole-like recess 1 a in the lead head 1 in a form-fitting manner and without any conicity.
  • the lead head 1 can additionally be connected to the cylindrical pin 3a of the upper part 3 of the plug with at least one punch 7. The soft material of the lead head 1 penetrates into the cylindrical pin 3a of the plug at the location of this punch 7.
  • the central part 4 and the lower part 5 of the plug are circular in cross section.
  • the diameter d of which is equal to the diameter d 'of the central part 4.
  • the opening of the annular joint 5a points in the direction facing away from the upper part 3, that is to say in the drawing below and is surrounded by a lip 5b.
  • the predetermined breaking point denoted by 6, which is subjected to shearing when fired, is the lateral surface between the part of the middle part 4 penetrating into the lower part 5 and the part of the lower part 5 surrounding this part.
  • the upper part 3 of the plug is delimited by a lower end face 3b, into which the middle part 4 merges. It is provided on the middle part 4 as a position during the flight of the projectile for the lower part 5 approach 4a, the distance a between this and the end face 3b being equal to the thickness D of the lower part 5.
  • the approach 4a forms part of the Middle part 4, so consists of the same material, namely elastic plastic.
  • FIG. 5 of the drawing 8 denotes the cartridge case, in whose lower part the propellant charge 9 is arranged.
  • An intermediate piece 10 is arranged between the lower part 5 of the plug and the propellant charge 9.
  • a central, cylindrical chamber 11 is provided, the diameter 12 of which is larger than the diameter d 'of the central part 4 of the plug.
  • the chambers is connected to the propellant charge 9 receiving part of the cartridge case 8 via a bore 13 which is dimensioned such that no powder particles, but highly stressed powder gases can penetrate into the chamber 11 during the duration of the shot.
  • the operation of the shotgun cartridge is as follows:
  • the individual parts of the cartridge assume the position shown in FIG. 5 of the drawing.
  • the gas pressure acting on the lower part 4 of the plug causes the predetermined breaking point 6 to respond, with the result that the lower part 5 moves upwards along the central part 4 of the plug, that is to say in the direction of the barrel mouth.
  • the middle part 4 passes over the shoulder 4a, which in the end position - in which the lower part 5 bears against the end face 3b of the upper part 3a of the plug - engages under the lower part 5.
  • the lead head 1 and the plug now form an inseparable unit and move towards the targeted target, while the intermediate piece 10 which may be used is ejected shortly behind the mouth of the barrel.
  • FIG. 7 makes the compact unit of the parts reaching the target and the extremely favorable location of the center of gravity of these parts particularly clear.
