  • a fuze On the upper part of the body 1 is mounted a fuze provided with an impact system 16 and a delay system 17 locked by a single straight arming pin 18 kept in place by a tape 19 whose end bears an open-ring 20 maintained in a waist 38a of the barrel 38 prolongated by a widen part 380 as represented in FIG. 10; above said arming pin which isolates the primers 21 from the transmission compounds 22, so making a fire barrier,
  • FIG. 9 is an end-on view of a percussion unit, showing the fire barrier
  • FIG. 10 is a partial external view showing the marks on the cap and the open-ring;
  • FIG. 11 is a partial longitudinal section of the pro-- in fire position
  • the parts of the present fuze are very simply manufactured and are mounted by simple superposition of the base 36 bearing gudgeons 37, the barrel 38, the selector 23, the plate 26 and the cap 35.
  • the container (FIG. 17) is composed of two semicylinders 39 and 40 notched laterally, pierced towards the middle by the holes 41 for receiving the nipple 42 of a support 43; this support 43 is prolongated in front with a sheath 44, a launching tube 45 and a propulsive cartridge; this support can be fitted onto the convex side of one semi-cylinder 39 as seen in FIG. 16.
  • the other semi-cylinder 40 can be used as a support for the sheath 44 at a selected angle for launching the projectile.
  • the impact system 16 comprises a striker 16a with its locking ball 16b which passes into the housing hole 160 of the pusher-primerholder 16d laterally disposed ahead of the ball in its locking positron.
  • the cap is opened at its upper nose portion 47, which permits the immediate penetration of particules and elements of the impact surface (earth, sand, snow, water, etc.
  • This orifice may be closed by an orifice-cover 48 which can be deformed by lengthening or by rupture, and made for instance of rubber or plastic; this orificecover may be a part of the cap 35, being only a deformable portion of it.
  • the inertial mass 29 may have a part 49 in contact with the orifice 47 in order to be driven back instantaneously at the very moment of the impact of the projectile.
  • the fuze contains only the delay system 17.
  • the compounds 22 for tire transmission are located in the base 36.
  • the striker of the delay system is locked by the arming pin 18 which is maintained by the tape 19 ending with an open-ring 20.
  • a hole 27 gives passage from the upper housing 50 to the outside, in such a way as to offer an escape-release in case of an accidental firing of a primer, and to assure the tire barrier, that is to say the non-communication of the fire to the transmission compounds 22.
  • the fuze and the tail are simplified.
  • the inertial mass 51 has a spheroid shape and the orifice of the cap 35 is situated above the tangent circle of the inertia device 51 with the cap 35.
  • the tape 19 and the open-ring 20 are prevented from turning in their housing 38a by the presence of a stop 52 and a roughened surface 38b.
  • the sheath 3 and the bottom 4 of the body 1 have an external diameter equal to the diameter of the fin-assembly 7.
  • the tail 6 is bored internally with fire channels 13 partly coaxial, opening outside in 53 and 54 and bypassing the fire jet to the propulsive charges 11.
  • the tail 6 may have a simple tubular shape, with the end opposite to the fin-assembly 7 attached to an air-tight closing 55 adapted onto the bottom 4 of the body 1.
  • the fuze is modified.
  • the impact system 16 is maintained by a washer 56 joined to the barrel 38.
  • the delay part 22a of the fire transmission compounds 22 of the delay system 17 is housed in a duct 57 substantially circular whose dimensions permit a long delay of combustion.
  • a washer 58 and a closing disc 59 which assure the air-tightness of the delay compounds 22a are turned in such a way that their openings 60 are diametrically opposed to the ignition entry to let the delaycompound 22a burn at the same time in the two semi-circles of the channel 57, as shown in FIG. 23, whereas in FIG. 24 the position of the openings 60 and the interruption of the delay compound (in 61) assure a longer delay; in FIG. 24, the duct 57 may have a helicoidal shape.
  • the construction of the projectile as described above provides for its use in a variety of ways.
  • An assembly of the body 1 with its explosive charge and the fuse assembly can be used as an offensive handgrenade.
