Definitions

  • This invention relates to a fuse for gyratory projectiles fired in rifled guns and'more particularly to a combined percussion and self-destruc tion fuse of the kind in which arming is efiected by a centrifugal device.
  • the action of the centrifugal device which effects the arming of the fuse is retarded by a pneumatic brake so as to obtain a certain safety distance beyond the muzzle of the gun.
  • Fig. 1 is an axial section of the fuse at rest
  • Fig. 2 is a similar view of the fuse in the armed condition.
  • the fuse comprises a body made of two pieces I and 2.
  • the percussion means comprise a striker 3 which is covered by a cap 4.
  • the striker 3 When at rest, the striker 3 rests with its flange 3a on a row of balls 8 or other locking members disposed in an inclined race la in the fuse body I. from the primer 4a by the locking balls 8. These balls are held in position by an annular member or sleeve 9, which in turn is locked by a split ring Hi located in a groove in said annular member 9 and adapted to'open under the influence of centrifugal force.
  • the self-destroying system comprises a hammer or hub 5 having housings 5a in which are located balls 6 or other catching members.
  • the annular member 9, is locked by a split ring l0 lodged in a channel or groove 9c of the annular member 9, said split ring engaging a shoulder 9d of the fuse body.
  • the device operates as follows:
  • the primer could be mounted, in a known manner, in a movable primer carrier.
  • a combined percussion and self-destruction fuse for projectiles fired in rifled guns comprising a fuse body, firing members in said fuse body and including a striker and a primer, said firing members being adapted to be urged against each other through direct action of an obstacle encountered by the projectile on its trajectory, locking members interposed between said firing members, a sleeve surrounding said locking members for maintaing the same in locking position, a hammer adapted to slide in the fuse 'body for engaging one of said firing members whereby to thrust the firing member against the other of said firing members to produce selfdestruction of the projectile, said hammer being provided with laterally extending holes, centrifugal catching members lodged in said holes and adapted to slide therein, a spring urging said hammer into engagement with the firing member with which it cooperates, said sleeve being provided with a groove with which said centrifugal catching members are adapted to engage under the effect of centrifugal force caused by the gyratory motion of the projectile, said centri
  • a combined percussion and self-destruction fuse as claimed in claim 1, wherein the sleeve is provided with an external circular channel and the fuse body is provided with a shoulder in the region ofsaid channel, and wherein a yieldable split ring is disposed in said'channel and is adapted to cooperate with said shoulder to lock the sleeve in a position of rest, said split ring being adapted to escape from the locking position by inertia at firing whereby to unlock said sleeve.
