Definitions

  • Thi occurrence is a consequence of the fact that when being introduced into the cartridge chamber by the breechblock on its forward stroke the cartridge first receives a blow which imparts to it a velocity exceeding the velocity of the breechblock on its forward travel.
  • the cartridge moving in advance of the breechblock falls in front of, and not into, the extractor claw.
  • the subject of the present invention is a special design of the cartridge, intended to prevent the cartridge from being accelerated overmuch by the breechblock in it forward travel, and consequently from falling in front of the extractor claw.
  • this object is secured by designing the cartdige in such a manner that it damps the blow struck on it by the breechblock.
  • the cartridge case may be fastened on the projectile shoulder at a certain interval from the guide ring of the The fastening may be secured by the cartridge case being made conically crimped in front and also made to fit a corresponding tapering shoulder of the projectile.
  • the cartridge case may also be fastened in a groove of the projectile by means of a fold.
  • the cartridge case may further consist of several parts, these being designed so as to be slidable one over the other.
  • the case bottom may be inserted into the case by means of a fine thread which under the blow of the breechblock undergoes a slight deformation, thus exercising a damping effect.
  • the case bottom may be provided with deformable elevations.
  • a cartridge designed according to the invention does not fall any longer in front of the extractor claw. This is due to the fact that the blow struck by the breechblock travelling forward on the cartridge to be introduced into the cartridge chamber does no longer cause the cartridge to travel in advance of the breechblock, the blow in this case merely forcing the cartridge case on to the projectile, or deforming the case itself, or the case bottom, at the spots intended for this purpose. In any case, care must be taken that the power required to bring about the deformation of the case in any one of the contemplated forms should be less than the 'moment of inertia of the projectile a it results from the projectile mass and the acceleration imparted to it by the breechblock.
  • FIGs. 1 to 6 of the attached drawing are shown a few constructional examples of realisation of the subject of the present invention.
  • Fig. 1 shows the position of the projectile in the cartridge case during transport.
  • Fig. 2 shows the position of the cartridge case I in relation to projectile 6, after the cartridge has been introduced into the cartridge chamber by the breechblock on its forward travel. Under the effect of the blow struck in the process of introduction the cartridge case has been forced on to the projectile 6 until, with its foremost end 2, it gets into contact with the guide ring 4 of the projectile 6.
  • the case I is designed in two parts. Parts I and 8 of the case I are shoved on to one another and fastened together by means of the wavy shape of the parts overlapping each other. Parts 1 and 8, however, are not in contact at the shoulders 53 and [0. It is only under the effect of the blow struck,on the case in the process of introducing the cartridge into the cartridge chamber that the parts 7 and 8 are shoved on to each other until they are in contact at the stops 9 and I6, and take up the position represented in Fig. 4.
  • Fig. 6 shows a constructional example in which the damping of the blow struck on the cartridge by the breechblock takes place by means of slightly deformable elevations l3 provided on the case bottom.
  • a cartridge case having a foremost crimped portion enclosing said rear end of the projectile and located within said recess and terminating at a distance from said guide ring during transport, said cartridge, casefmoving in relation to said projectile and the foremost 5 portion thereof contacting said guidering as ,
