Definitions
- This invention relates to a method of and means for throwing grenades by means of firearms.
- Modern firearms, and more especially semi-automatic orautomaticrifles are generally provided with a muzzle tion of the pressure exerted on the end of the tail of the grenade owing to the lateral escape of a part of the gases through the said vents and, in consequence, a detrimental loss of velocity.
- the sleeve of the present invention is equally well suited for throwing grenades by means of such weapons. It may be fitted to all the types of such weapons hereinbefore described, without entailing modification of their barrels, and it enables the aforementioned drawbacks to be obviated.
- the sleeve according to the invention is characterised in that it comprises means which, on the one hand, enable it to be maintained on the barrel of the weapon in such manner that it can be detached therefrom when the shot has been fired so that when throwing occurs it is projected forward after the grenade, and, on the other hand, enable the displacement of the sleeve on its support to be effected at a very reduced speed in relation to that of the grenade.
- the sleeve of the present invention When the sleeve of the present invention is intended for throwing grenades by means of firearms in which the barrel is provided with a muzzle brake or a similar device, it constitutes at one and the same time a diseharger cup on which the tail of the grenade is fitted and an obturator intended to mask at least partially the ice 2, ventsof the said muzzle brake, the velocity communicated to it, which is very low in relation to that of the grenade, enabling it to mask the said vents for at least the greater part of the propulsion path of the said grenade.
- the invention also relates to a method of throwing grenades by means of the hereinbefore described sleeve, which is characterised in that a sleeve is disposed inside the tail of each grenade and the assembly formed by the latter and the said sleeve is fitted on the barrel of the weapon.
- FIGURE 1 is a longitudinal section of the sleeve supporting a grenade and fitted on the barrel of. a firearm ,provided with a muzzle brake;
- FIGURE 2 is a similar view of the sleeve of FIGURE 1, but in a difierent position in relation to the barrel of the weapon;
- FIGURE 3 shows a modification of the sleeve
- FIGURE 4 shows another modification of the sleeve.
- FIGURE 1 shows the end of the barrel 1 of an automatic rifle, which barrel is provided with a muzzle brake comprising a series of vents 2.
- the throwing of anti-tank, anti-personnel, smoke, and other rifle grenades by means of such a weapon is effected by means of a tubular sleeve 3 which is retained inside the tail of each grenade and which is intended to be fitted with slight friction on the barrel 1 so as to mask the said vents 2.
- the inner wall of the sleeve 3 has a collar 4 adapted to abut against the end of the barrel 1 for the purpose of locating the sleeve on its support.
- the sleeve 3 also has a retaining device constituted by an elastic metal ring 5 housed in a groove 6 in the inner wall of the sleeve, said ring being adapted to exert on the periphery of the barrel 1 a clamping force sufficient to ensure that the sleeve is held in all the circumstances imposed by firing in the field, especially firing when the nozzle of the barrel is pointed downwardly.
- a similar retaining device constituted by an elastic metal ring 7 housed in a groove 8, is disposed at the periphery of the sleeve 3 for the purpose of holding it inside the tail 9 of the grenade.
- the major part of the propulsion gases issuing from the cartridge, bearing on the end of the tail 9 of the grenade, causes the latter to be projected forwardly.
- FIGURE 3 shows a modification of the sleeve of FIG- URES 1 and 2, in which a collar 4a, constituted by .a separate metallic ring, is secured to the sleeve 3 by crimping.
- the modification illustrated in FIGURE 4 relates to the device retaining the sleeve on the barrel of the weapon.
- This device consists of a clamp 10 comprising on the one hand a series of elastic strips 10a held in a housing 11 provided in the inner wall of the sleeve for the purpose of securing said clamp to the latter, and on the other hand a series of elastic strips 10b adapted to exert a retaining force on the barrel of the weapon.
- the sleeve of the present invention can be applied equally well to the throwing of grenades of the rifle, and means to move 'the sleeve forwardly ifr'oinftlieibafreli with the grenade, 'coni'pr ising an aper- .tlired r'n'emher projecting inwardly f r'c51'11"th'e sleeve 'in 7 front of the rifle barrel and in the path of 'the"gas'e"s from the barrel.
- r 2 In'com'bination with a rifle having a vented muzzle brake and a rifle grenade having a hollow tail section adapted to be mounted over the barrel of said rifle, a
