Definitions

  • the present invention relates ,to a fuse, in which all the above-mentioned drawbacks of fuses as hitherto made areovercome, The invention'consists substantially in this that the fuse is so constructed as to contain no explosives or detonators whatever, but only mechanical parts.
  • a fuse of such construction can be stored and transported as a complete unit entirely separate from the projectile proper and be completely protected from moisture.
  • air-tight'containers may for instance be used.
  • projectiles provided with fuses constructed in this manner all the explosives and detonators are housed in the projectile proper or in a separate casing.
  • the projectile For protecting the explosive of the projectile, the detonator and the like from the ac tion of moisture or from mechanical influences the projectile is closed with a separate air-tight cover or closing plate, which is removed before the fuse proper is screwed into the projectile.
  • the needle On the fuse proper being screwed in, the needle, which is acted on by a spring, centrifugal force or the like, comes in front of the detonator of the projectile itself, in order that the latter may be caused to explode at the required moment.
  • a separate closure is provided between the needle of the fuse and the detonator of the projectile, which protects the detonator from the needle or from external action, when the fuse is not screwed on.
  • This separate closure is opened or displaced only at the moment of firing by centrifugal or some other suit- .to the needle 16.
  • the closure may also be opened or displaced by the shock at the moment of firing or by a separate partof the actual mechanical fuse travelling through a certain path in the fuse.
  • the closure may either be located in the actual fuse part of the mechanical fuse or preferably directly in the projectile or casing, in which the dotonator is located, in which latter two cases,
  • the detonator is also protected from external mechanical influences.
  • the needle is visible, easily accessible and therefore capable of being inspected.
  • a further filler member 12 is provided, which has a slot 13 on one of its sides, in which a small plate 14 can move radially.
  • the plate 14 when in its position of rest, covers the passage 15, through which the needle 16 of the mechanical fuse causes the detonator 4 and the projectile to explode.
  • the small plate 14 On the projectile being fired, the small plate 14 is displaced radially by centrifugal force, so that the passage 17 comes into alinement with the passage 15, thus giving a free path
  • the plate 14 can be displaced by a spring or-some other force, which acts at the moment of firing.
  • the constructional form shown with the movable plate 14 is only one of the many possible ways'of protecting the detonator from undesirable infiuences and will therefore be referred to below only as the closure.
  • the body 10 of the projectile may be extended so as to receive the whole mechanism, which is otherwise contained in the intermediate part.
  • the mechanical fuse l' is unscrewed (Fig. 2) and is enclosed in an air-tight container.
  • the projectile itself is closed at the end which is open, when the fuse is screwed ofi, in an air-tight manner by means of a separate cover.
  • the cover may also be a screw,
  • I 3 The combination of a projectile with a mechanical fuse, the fuse proper containing only the mechanically acting parts of the fuse, a part intermediate of the projectile and the fuse, into which the fuse is screwed and which part is screwed into the projectile, a separate releasable closure in the intermediate pa'rt between the needle of the mechanical fuse and the detonator, a holder (5) capable of being screwed into the intermediate part and of containing the detonator, a plug (7) for holding the detonator in the holder (5), and a filler member (12) capable of being screwed into the intermediatepartr above the detonator and containing a recess on one slde 1n which the closure can move radially, as set forth.
