Definitions

- 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.

- 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.

- 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.

Abstract
Description
- 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.
- 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.
- 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.
- Now the invention shall be described more in detail with reference to the accompanying drawings. In the drawings Figure 1 is an example of a weapon system with a barrel having a muzzle cover according to the invention, and 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 asight 3, and anammunition part 4 including abarrel 5, acombustion chamber 6 and a funnel formedend nozzle 7. At the rear end of the barrel 5 a non-illustrated shell is pre-mounted and the fireing of the shell is made by anon-electric fuse 8 extending from thefireing apparatus 2 into the shell. On the barrel a combined shoulder support-cheek support 9 and asupport cushion 10 are mounted. Thesupport 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. - At the muzzle the barrel has a
muzzle cover 11 which like the shell is mounted in connection to the manufacture of theammunition 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 thebarrel 5 and which carries adiaphragm 13. Preferably thecollar 12 is slightly conically widened from thediaphragm 13 and it has an average diameter which is slightly less than the outer diameter of thebarrel 5 so that the muzzle cover has to be pressed on thebarrel 5. At the connection portion between thecollar 12 and thediaphragm 13 the muzzle cover is preferably formed with ashoulder 14 which provides a supporting edge to the front edge of the barrel. Theshoulder 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 thecollar 12 and thediaphragm 13 is formed as a recess 15'which provides a kerf for blowing thediaphragm 13 out when launching the shell. For this purpose therecess 15 has slightly less thickness than the remaining part of the diaphragm. Thediaphragm 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 thecollar 12 to stick to the barrel when launching the shell. Therefore thediaphragm 13 is concavely bent inwards whereas therecess 15 is bent outwards. In order to provide a good clamping of the collar to the outside of the barrel when launching the shell thecollar 12 is made gradually thinner towards the rear free end thereof. - In a practical embodiment of the muzzle cover according to the invention for a fire tube having an inner diameter of 85 mm the
collar 12 of the muzzle cover was made with a largest thickness round the barrel of 5 mm, whereas thediaphragm 13 was made having a thickness of 0,75 mm. Therecess 15 was formed with a thickness of 0,4 mm. Thediaphragm 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 thecollar 12 it may be quite sufficient that thecollar 12 is pressed onto the muzzle of the fire tube without any further securing means. - 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 thediaphragm 13 is blown out and is ruptured round therecess 15 thereby leaving a free race for the shell. Depending on the stress when the diaphragm is pressed out from its concave to a convex form there is some floating of material in thecollar 12 at the same time as thecollar 12 by the pressure is rotated outwards-rearwards round theshoulder 14, whereby the collar is pressed stronger to stick to the barrel. This prevents the collar from being released and thereby from inflicting the throw path of the shell. - It is to be understood that the muzzle cover described above and shown in the drawings is only an illuminating example and that all kinds of different modifications may be presented within the scope of the appended claims.
