Definitions

  • the present invention aims at risk and rifle or forgets to remove from it, a ball cartridge at the time of tiring the grenade.
  • the grenade launcher of the present invention which is intended to serve for tiring rifle or other firearm grenades, is of the type comprising -a tube serving as barrel and provided at its rear end with a manual fixing means connecting it rigidly to the lrearm.
  • retaining means adapted to yield under the shock of an inadvertently tired ball cartridge and to drive said core towards the front where it is stopped at the front part of said chamber leading into the tube of the grenade launcher, while the ball is crushed inside a cavity provided at the rear of the core.
  • the grenade launcher has two transverse apertures the core, between two successive longitudinal cavities in the latter.
  • the retaining means preferably comprises a plurality of pins which are integral both with the launcher and with the core occupying said chamber.
  • the aforesaid metal core which is preferably bi-ogival in shape, is hollowed at its front end so as to permit the ball which strikes it to penerate into said hollow, where it is crushed after having passed through a hood promotes the flow of the gases towards the periphery of the core during normal firing with the blank cartridge intended for tiring the grenade.
  • Figure 1 is a partial axial section on the line 1-1 of Fig. 4;
  • Figure 2 is a plan View, according to Figure 1;
  • Figure 4 is a section along .the line 4-4 of Figure 2.
  • FIG. 1 denotes the barrel tube of the grenade launcher mounted at the end 2 of a rifle with the aid of a fixing device 3.
  • An axial chamber 4 screwedon to the tube 1 at 5, serves as a housing forl an oblong metallic core 6 having ogival ends. Pins 7 penetrating into the body of the core 6 and passing through the ywall of the chamber 4 secure said core to said chamber.
  • the outside surface of the core 6 comprises longitudinal hollows 8 providing passages (four in the embodiment illustrated) between the core 1 and the wall of the chamber 4, the latter communicating with the outside through apertures 9 and 10.
  • An axial and cylindrical inlet 11 provided in the core 6 opposite the end of the rifle is preferably closed by a hood 12 having a rounded head.
  • the launcher also has an elastic ring 13 serving to retain the grenade (not shown) when the latter is placed on the barrel tube 1.
  • a sighting frame 14, adapted to pivot at 15, can be folded back. In the operative position ( Figure l) the frame 14 masks the eld of View of the foresight 16 of the render, s0 that the user automatically remembers to remove the grenade launcher when tiring ordinary ball cartridges.
  • the rieman after having placed a grenade on the barrel 1 of the launcher, sights with the aid of the frame 14 and fires. If he has used a blank cartridge, the propulsion gases on encountering the core 6 will diverge and pass through the longitudinal hollows 8 and then penetrate into the barrel-tube 1, projecting the grenade towards the target. If by error the cartridge is a ball cartridge, the ball will penetrate into the cavity 11 of the core 6, yielding a part of its kinetic energy to the latter. The pins 7 are sheared under the shock and the core 6 moves forward until it encounters the part of smaller diameter of the barrel 1, whilefthe gases escape through the transverse apertures 9 and 10 freed by the forward movement of the core.
  • a grenade launcher having a front portion to hold a grenade and a rear portion to be xedly attached to a gun barrel, said rear portion comprising a chamber of greater diameter than the internal caliber of said launcher, a core of generally oblong shape inside said chamber, frangible means to secure said core axially in said chamber, said core having longitudinal passages at its periphery for the shape of which Figure 3 is a section along the line 3 3 of Figure 2;
  • a grenade launcher as described in claim 1I in which o said core has a normally closed rear cavity for receiving an inadvertently iired bullet.
