Definitions

  • the present invention relates to a muzzle cover for protecting weapons of the type comprising a barrel in which a shell or similar is pre-mounted and which has a fireing means providing a launching of the shell.
  • the barrels When handling such weapons, especially when the marksman moves there is a risk that gravel, sand and other particles enter the barrel thereby preventing the shell from leaving the barrel bore what may have disastrous consequences. Therefore the barrels generally are formed with some kind of muzzle cover to prevent particles from entering the barrel.
  • the muzzle covers which previously used to be made of sheet metal or any other stiff material had to be removed before the weapon was fired since otherwise there is a risk that the fire tube explodes before the shell has left the barrel or that the shell is actuated when penetrating the muzzle cover so that the shell gets another shooting angle than the intended one.
  • the muzzle cover In order to make sure that the muzzle cover is not damaged and that no particles have entered the barrel the marksman has to inspect the muzzle cover before shooting, the muzzle cover must be removed, and preferably also the inner of the barrel must be inspected. This is a time consuming operation which reduces the possibility for the marksman to quickly start the shooting.
  • Basis of the invention therefore is the problem to provide a muzzle cover which is formed so that the marksman by a quick and simple operation by the hand can control that the muzzle cover is undamaged and that consequently no particles have been able to enter the barrel, and to provide a muzzle cover which without disadvantages can be shot through by the shell.
  • the muzzle cover according to the invention also has to be formed so that it can stand such stresses from outside which may occur when the fire tube muzzle is hit by tree knots etc. in the nature.
  • Figure 1 is an example of a weapon system with a barrel having a muzzle cover according to the invention
  • Figure 2 is an axial cross section through a separate muzzle cover.
  • the weapon illustrated in Figure 1 generally comprises a weapon part 1 having a fireing apparatus 2 and a sight 3, and an ammunition part 4 including a barrel 5, a combustion chamber 6 and a funnel formed end nozzle 7.
  • a non-illustrated shell is pre-mounted and the fireing of the shell is made by a non-electric fuse 8 extending from the fireing apparatus 2 into the shell.
  • On the barrel a combined shoulder support-cheek support 9 and a support cushion 10 are mounted.
  • the support cushion 10 is a support for the barrel while resting on the shoulder of the marksman when shooting from a standing or knee standing position.
  • the barrel has a muzzle cover 11 which like the shell is mounted in connection to the manufacture of the ammunition part 4. Therefore the barrel is never left without a muzzle cover, and the muzzle cover is allowed to remain on the barrel when the shell is launched.
  • the muzzle cover is made of an elastic material, preferably rubber or synthetic rubber, and as best evident from Figure 2 the muzzle cover comprises a collar 12 which is intended to be mounted outside the barrel 5 and which carries a diaphragm 13.
  • the collar 12 is slightly conically widened from the diaphragm 13 and it has an average diameter which is slightly less than the outer diameter of the barrel 5 so that the muzzle cover has to be pressed on the barrel 5.
  • the muzzle cover is preferably formed with a shoulder 14 which provides a supporting edge to the front edge of the barrel.
  • the shoulder 14 has a slightly less radial dimension than the thickness of the barrel so as not to provide an obstacle for the shell while being launched from the barrel.
  • the transition portion between the collar 12 and the diaphragm 13 is formed as a recess 15'which provides a kerf for blowing the diaphragm 13 out when launching the shell.
  • the recess 15 has slightly less thickness than the remaining part of the diaphragm.
  • the diaphragm 13 has to be completely free from stresses both in order to stand stresses from outside and to be able to provide a clamping of the collar 12 to stick to the barrel when launching the shell. Therefore the diaphragm 13 is concavely bent inwards whereas the recess 15 is bent outwards.
  • the collar 12 is made gradually thinner towards the rear free end thereof.
  • the collar 12 of the muzzle cover was made with a largest thickness round the barrel of 5 mm, whereas the diaphragm 13 was made having a thickness of 0,75 mm.
  • the recess 15 was formed with a thickness of 0,4 mm.
  • the diaphragm 13 was made concavely inwards with the largest concavity of 5 - 8 mm.
  • the muzzle cover can be glued or vulcanized or secured in any other way to the barrel 5, but depending on the conical and special form of the collar 12 it may be quite sufficient that the collar 12 is pressed onto the muzzle of the fire tube without any further securing means.
  • the marksman When making the weapon ready for shooting it is quite sufficient that the marksman slightly hits the diaphragm 13 whereby a specific resonance sound appears in the barrel if the muzzle cover is undamaged whereas another sound appears if the muzzle cover should happen to be punctured. Therefore the marksman can quickly and effectively judge whether or not the muzzle cover is undamaged or not. If the muzzle cover is undamaged the shell is launched, and depending on the pressure thereby appearing in the barrel the diaphragm 13 is blown out and is ruptured round the recess 15 thereby leaving a free race for the shell.
