Definitions

  • A denotes the body of the fuse and B the fuse rings of the slow combustion fuse which contain the burning composition Z)".
  • a firing plunger C adapted to ignite the burning composition 5 and containing a primer 0 and enclosed by a holder D of Ushaped formation.
  • a plate E which carries a substantially conical shaped cap 6 mounted coaxially with the longitudinal axis of the fuse.
  • an approximately conical shaped hollow cap E the longitudinal axis of which coincides with the longitudinal axis of the fuse.
  • This cap E has on its upper end a circular through aperture e the centre point of which lies in the axis of the fuse.
  • the hollow conical shaped annular space which is formed by the cap E and e communicates through a boring e in the plate E with a passage a in the body A of the fuse running parallel with the axis of the latter, and from which a passage arranged obliquely to the axis of the fuse leads to the burning composition 6
  • the passages b and a the boring e and the annular space 6 with the opening a constitute the only means of connection between the burning composition b and the outer air.
  • This passageway 6 c 6 0 ,0 opens to the air in the direction of the longitudinal axis of the fuse.
  • the air which is contained in the hollow space 6 a 0 e undergoes considerable compression under the influence of the progressive velocity of the projectile, and the point at which the burning composition burns away, is therefore always under considerable pressure.
  • the centrifugal force which the air contained in the hollow space is subjected t0 also acts in a direction, which increases the pressure at the point of ignition.
  • the action of the pressure produced at the point of ignition in'the manner described has the advantage that too sluggish a combustion or even the extinction of the burning composition is eliminated witlr certainty and moreover even when the projectile has a very high speed of rotation or when a height is reached at which there is only a very small air pressure.
  • a slow combustion fuse for projectiles comprising a body provided with a cylindrical extension, fuse rings carrying a slow combustion fuse secured to said body, a firing pin mounted in said extension, a plate screW-threadedly engaging said extension and provided with a cap, a conical hollow cap open at its front end and centrally thereof screw-threadedly engaging said plate and forming with said first mentioned cap a hollow conical-shaped annular space, said body and fuse rings being formed with a passage-way providing communication between said annular space and said burning composition of the combustion fuse.
