Definitions

  • This invention relates to a percussion mechanism intended more especially for weapons of the rocket throwing type.
  • the mechanism according to the invention comprises inside a case, a striker-carrying hammer which on firing is swung down, by the propulsive gases of the rocket, against at least one percussion spring, a cocking sear and a safety sear each adapted, in the active position to hold the said hammer in the cocked position, a lock for fixing the projectile, which look projects in part into the barrel of the weapon and the withdrawal of which is effected either manually or automatically by the said hammer on percussion or else by introduction of a projectile into the barrel of the weapon, and a trigger device actuating the cocking sear, the said mechanism being characterised in that the withdrawal of the lock controls the movement of the safety sear into the active position.
  • the safety sear after being brought manually into the inactive position, is held in this position, against an opposing spring, by a pawl the release of which is effected either manually or by withdrawal of the said lock.
  • the cocking sear contains a control arm the free end of which projects beneath the case of the mechanism and which can be connected to a supplementary trigger system.
  • This arrangement enables the mechanism to be operated remotely if desired, for example by traction on a cord connected to the said sear.
  • the mechanism contains a rigid shock-absorber adapted to oscillate about an axis 2,941,448 Patented June 21, 1960
  • Figure 1 is a general view, on a reduced scale, of a rocket-thrower;
  • Figure 2 is a longitudinal section of the trigger device
  • Figures 3 to 5 show in elevation and with the case in section three phases of operation of the mechanism of the invention.
  • the rocket-thrower shown in Figure 1 comprises essentially a barrel, open at both ends, a trigger device housed in a butt 1 and a percussion mechanism disposed inside a case fixed to the rear end of the barrel.
  • the trigger device comprises a trigger 2 pivoting about the axis 3 and provided with a lever 4 pivoted at 5; the lever 4 is urged rearwardly by a spring catch 6 the tension of which is adjustable by means of the screw 7.
  • a second lever 8 mounted on the pivot 9 bears by its lower part on the stop 10 while its upper part is in contact with a transmission rod 11 which connects the trigger device to the percussion mech anism; a return spring 12 connects the trigger 2 to the lever 8. Firing safety is ensured by manual rotation of a safety means 13, in the form of a half-circle, the convex part of which limits the travel of the lever 8.
  • the firing mechanism ( Figures 3 to 5) disposed inside a case 14 comprises: a hammer 15 carrying a striker 16, a cocking sear 17, a safety sear 18, and bell-crank lever 19 and a lock 20, the latch 21 of which is adaptedv to project into the barrel of the weapon.
  • the hammer 15, journaled about a pivot 22, has two recesses 23 and 24; the first one, 23 forms a projection which, bears, on
  • the second 24, engages, in Figures 3 and 4, with at least one of the scars 17 and 18, which holds the hammer cocked against a percussion spring 26.
  • the latter is fixed on the one hand to a pin 27 of the said hammer and on the other hand to a metallic piece 28 or yield able shock-absorber adapted to oscillate about a pivot 31, has at the rear a nose 35 adapted to engage with a pawl 36 after lowering of the cocking lever F disposed outside the case 14 and movable, through the square 37, with the sear 18.
  • the springs 38 and 39 return the scars 17 and 18 to the active position, towards the hammer 15.
  • the bell-crank lever 19, mounted on a shaft 40, has an arm 41 the end of which engages with a certain clearance in a recess 42 of the lock 20.
  • the pawl 36 is carried by the other arm of the lever 19.
  • a spring 43 urges the lever 19 about the axis 40 in the counterclockwise direction.
  • a lever S carried by the square 44 of the shaft 40 controls the angular displacement of the lever 19 and hence that of the arm 41 and of the pawl 36.
  • the lock 20 has two articulation arms 45, parallel to one another (only one is shown in Figures 3 to 5), adapted to pivot about the shaft 40.
  • the free end of 3 the arm 45 is urged downward by a spring 46 the traction of which keeps the latch'21 projecting intothe barrel of the weapon.
  • the percussion mechanism operates in the followingv manner: 7 p I p
  • the safety means 13 By placing the safety means 13 int'o the position shown in Fig. 2, the marksman cocks-the trigger device, while the ammunition server operates the lever F ,(Fig! 3) to free the safety sear 18, as shown in Fig. 4, and the nose 35engages with the pawl 36. anism is cocked.
