Abstract

Abstract A muzzle cover for fire arms of the type having a barrel (5) through which a shell or a similar projectile is intended to be launched. The muzzle cover is made of an elastic material and comprises a collar (12) which carries a flexible diaphragm (13) and which is adapted to be pushed over the muzzle of the barrel (5). The diaphragm (13) is bowed concavely inwards and is integral with the collar (12) over a recess (15) which is bowed convexly outwards and has a reduced thickness of material as compared with the diaphragm (13). The recess (15) provides a kerf for removing the diaphragm (13) when the pressure in the barrel (5) has increased to a predetermined level when the shell or similar projectile is launched. The collar (12) is slightly conical so that the muzzle cover can be forced onto the barrel, and the collar (12) has a successively reduced thickness in the direction rearwardly.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 92 words
Muzzle cover for weapons having a barrel (5) through the muzzle of which a shell or a similar projectile is intended to be launched, characterized in that the muzzle cover (6) comprises a collar (12) which is pushed over the exterior muzzle end of the barrel and which carries a diaphragm (13) which can be broken through depending on the pressure appearing in the barrel when the shell or similar projectile is launched, whereby the diaphragm (13) is broken away from the collar (12) thereby leaving a free passageway for the shell.
Claim 2
Dependent Claim 92 words
Muzzle cover for weapons having a barrel (5) through the muzzle of which a shell or a similar projectile is intended to be launched, characterized in that the muzzle cover (6) comprises a collar (12) which is pushed over the exterior muzzle end of the barrel and which carries a diaphragm (13) which can be broken through depending on the pressure appearing in the barrel when the shell or similar projectile is launched, whereby the diaphragm (13) is broken away from the collar (12) thereby leaving a free passageway for the shell.
Claim 3
Dependent Claim 31 words
Muzzle cover according to claim 1, characterized in that the diaphragm (13) is integral with the collar (12) over a recess (15) having a slightly less thickness than the diaphragm (13).
Claim 4
Dependent Claim 24 words
Muzzle cover according to claim 1 or 2, characterized in that the diaphragm (13) is formed concavely inwards whereas the diaphragm is formed convexly.outwards.
Claim 5
Dependent Claim 42 words
Muzzle cover according to any of the preceding claims, characterized in that the collar (12) is formed with a shoulder (14) providing a support edge to the muzzle of the barrel (5) and which is narrower than the thickness of the barrel.
Claim 6
Dependent Claim 45 words
Muzzle cover according to any of the preceding claims, characterized in that the collar (12) is slightly conically widened from the outer end thereof and rearwardly and in that the average diameter of the collar is less than the outer diameter of the barrel (5).
Claim 7
Dependent Claim 26 words
Muzzle cover according to any of the preceding claims, characterized in that the collar (12) has a successively reduced thickness of material in the direction rearwardly.
