Definitions

  • a fuze having a body axiallybored with a hollow striking pellet coaxially arranged in the axial bore of the body and containing an ignition train formed of a front priming cap, a delay element, a match and a rear priming cap, all the elements forming the train being arranged in alignment and in immediate succession to each other, the rear priming cap being arranged to be ignited either upon impact thereof against an ignition needle upon striking of the fuze against a target or through direct ignition from the said match if the target is missed.
  • the striking pellet is fastened to the fuze body by means of a metal latching element which is arranged transversely of the body of the fuze and to be disengaged from the striking pellet to permit the axial displacement of the latter only after the delay element burns.
  • Figure 1 shows an axial section of the fuze
  • Figure 2 shows a right side elevation of the device of Figure 3;
  • Figure 3 is a cross-sectional view of an alternative system for trajectory safety device, according to this invention.
  • Figure 4 is a left side elevation of ure 3.
  • the reference numeral 1 indicates the body of the fuze provided with an axial bore wherein the striking pellet 4 which is axially bored is located.
  • an ignition cap 2 is arranged which is held in fixed position by a spring 3 and protected by a metal disc 16 inserted in the striking pellet. Facing the ignition cap 2 there is an apertured needle housed in a recess made inside the pellet 4.
  • a transverse hole 17 is provided and in the wall of the striking pellet 4 there is provided a hole 6 for the passage of the flash efiect from inside to outside of the striking pellet.
  • a priming cap 9 which faces the apertured needle 12 carried by the plug 18 of the body of the fuze.
  • a pawl 10 which freely rotates about a pivot 11.
  • a recess 19 is provided registering with the hole 6 in which recess registering a latching element 8 is located which in the position shown in Figure 1 acts as a safety stop member for the striking pellet 4.
  • the latching element 8 is axially bored and is provided with a cavity wherein a gunpowder charge 15 is contained.
  • the recess 19 is closed by a sealing plate 7.
  • the safety element 21 is provided with a second cavity containing an auxiliary delay charge 22.
  • the ignition cap 2 When the projectile is fired the ignition cap 2 is disthe resistance of the spring 3, it strikes the apertured needle 5 and by its combustion ignites the compressed gunpowder match 13, the first portion 14 of which forms the delay ofthe trajectory safety device. When said delay 14 has been burned, the ignition is transmitted through the hole 6 and the corresponding hole of the metallic latching element 8 to the gunpowder charge 15 therein contained which, on bursting, ejects the sealing plate 7 thus allowing the safety element 8 to be ejected due to centrifugal force 9 i
  • the fuze is cocked and is ready to act against a target ,the pawl 10, pivotedon the pivot 11 and held by a blocking element (not shown) has been displaced by centrifugal force, which can occur only when the acceleration of the projectile has ceased asuntil then the force exerted by the striking pellet 4 bearing into a recess in the pawl, keeps it in its safety position; (2) the delay element 14 has been burned and the metallic latching element 8 has
  • a percussion fuse for projectiles having a mechanism for self-destruction after a predetermined time comprising a fuze body provided with an axial bore and a rear recess in a continuation of said bore, a plug screwed in said recess and provided with a rear holed needle axially positioned in said plug, a hollow striking pellet coaxially arranged in said axial bore of said fusebody, said striking pellet containing an ignition train comprising a fore priming cap, a delay charge, a match and a rear-priming cap, said elements comprising said ignition train being in alignment and directly succeeding one another, said ignition train further containing a holed needle interposed between said fore priming cap and said delay charge, said rear priming cap being in ignition relation with said holed needle of said plug, said hollow striking pellet having a wall provided with a transverse bore opening at the bottom of said delay charge, said fuse body being provided With a transverse bore registering with the transverse bore of said striking pellet, a metallic latchirig element slidably
  • a percussion fuze for projectiles having a mechanism for self-destruction after a predetermined time, which comprises a fuze body provided with an axial bore and a hollow striking pellet coaxially arranged in said axial bore, said striking pellet having a length substantially equal to the length of said axial bore of the fuse body, said fuse body being provided with a rear recess in a continuation of said axial bore, a plug screwed in said recess provided with a rear holed needle axially positioned therein, an ignition train contained in said striking pellet comprising a fore priming cap, a delay charge, a match and a rear priming cap, arranged in alignment directly succeeding one another, said ignition train further comprising a holed needle interposed be tween said fore priming cap and said delay charge, said rear priming cap being in ignition relation with said holed needle of said plug, a pawl pivoted at one end interposed between said rear priming cap and said rear holed needle of said plug when the fuse is inoperative and being
