Definitions

  • This invention relates to mechanical time fuses for artillery projectiles, which are arranged to ignite on impact when the time fuse, either because of unsuitable adjustment or because of faulty operation, does not act with retardation. More particularly the present invention has for its object a mechanical time fuse sensitive to impact.
  • retarded ignition takes place after a time that can only be approximately dimensioned, but not adjusted.
  • this is only possible with an axially arranged percussion cap, the arrangement being such that the ignition must be initiated by means of a spring.
  • the use of only one ignition member for retarded and impact ignition in artillery fuses which may be made to act with retardation and have accurate time adJustment, and with which the percussion cap is set in the axial direction by a spring, or in the radial direction by centrifugal force, sinot yet known.
  • the central shaft b of the clockwork, on which 10 is mounted the adjustment disc a is bored throughout its entire length. In this bore is guided the percussion bolt cwhich, upon impact of the projectile against any resistance, is pressed down. In order that this movement may not take place at the firing, a safety tub'e lying above the mechanism, but not shown, is provided for the percussion bolt 0.
  • the engaging lever e securely connected with the shaft (1 slides in the known manner with its bentup end or on the circumference of the adjustment disc a driven by the mechanism, until e1 falls into the aperture :11 of this disc, whereby the shaft d is subjected to a slight rotation, owing to which a lever f is able to enter the milled out recess d1 of the shaft d, which brings about the engagement of the ignition device of any desired form, which is not shown.
  • a mechanical time fuse for projectiles wherein sensitive impact ignition is effected comprising a central shaft disposed longitudinally in the said fuse, an adjustment disk rotatable about the said central shaft, a shaft having a recess and a locking lever adapted to engage radially with the said disk, said shaft initiating the time ignition by its rotation, a lever capable of entering the recess of the said shaft for producing ignition and a percussion pin guided in a bore in the central shaft and members for bringing about with the said disk, said shaft initiating the time.
  • a lever capable of entering the recess of the said shaft for producing ignition, a percussion pin for releasing the said time fuse for projectiles lever independently of the time ignition and a movable member adapted to be released by the percussion pin and shaped to form a bearing for the said shaft.
  • a mechanical time fuse for projectiles wherein sensitive impact ignition is effected comprising a central. shaft, an adjustment disk rotatable about the'said central shaft, a shaft initiating the time ignition by its rotation, a locking ,lever actuating saidlast mentioned shaft which engages radially with the said disk, a lever released by said locking lever for producing ignition, a percussion pin adapted to release the ignition producing lever independently of the time ignition, said last mentioned shaft being mounted in a movable member, a hook provided at the inner end of said member and a resilient part engaging with the said hook in its inoperative position and adapted to be bent if the percussion pin is forced downwards by impact of the shell, whereby the said member will disengage from the said part and shift outwardly with the shaftin order to release the lever and to effect the ignition.
