Definitions

  • elements ot' the fuse are adapted to be placed in position directly in the lodgment provided for them in the fuse body.
  • the fuse according to the. invention is essentially characterized by the feature that the rear element of the firing mechanism (preferably the percussion cap orprimer) is placed between two elastic supports ot' different degree of compressibility, the rear elastic support, of greater compressibility, resting upon the base of the lodgment provided in the fuse body, while the front support ot smaller compressibility abuts at the trout end against the-complementary member l-of the mechanism (preferably the striker') which is prevented from escaping outwardly relative 'to 'the fuse 'body by a shoulder formed upon said fuse body, said complementary member being free to make an inward movement over a limited distance determined by another stop also formedv upon the fuse body.
  • the rear element of the firing mechanism preferably the percussion cap orprimer
  • Figs. 2, 3, 4, 5 and 6 are similar views ot other embodiments ot' the invention.
  • A is a fuse lbody in which a lodgment A1 is provided for the whole ot ⁇ the tiring mechanism, which lodgnent com- D, of smaller compressibility than C 'bears at'its front end against the head Kl of the striker E.
  • The. latter isv ⁇ prevented from making any outward vmovement by a shoulder al formed upon the fuse body, ,forex-fy ample, by'turning in the-outer lip or edge ot' the latter.
  • the striker is adapted to make an' inward movement 'over a small distance,afte ⁇ r which it abuts against asho'ulder'az' also formed upon the fuse body A.
  • the diference in compressibility between the twosprings C and D ma be obtained by a dierence in section yo kind andthe springv C made longer than theV l springi'D.
  • the fuse When an obstacle is struck, even a very light one, such as the wing fabric'of an aeroplane, for example, the fuse operates instantaneously.
  • the striker K which'v may be lvery light, is driven intothe fuse body until it abuts against the shoulder a2 and this movementtakes place while the fuse body' A and the projectile,'penetrating into the very light obstacle or pushing the latter back, cont-inuetheir forward'V movement at the only slightly reduced speed of the 'projectil'eat that moment.
  • the per'- 'cussion'cap B the kinetic venergy l/2 m 172 of which is very high on-'account of the very A' high value-of the factor 172 j (where V is the residual speed of 'the projectile), compresses the spring D and strikes the point of the striker K.
  • the present invention is firedlfrom'a gun, tlieA force oi' set-back is ineective to produce impact between the striker and percussion cap, since spring, C is more readily compres--A sible than spring D, and preferably the mass of the percussioucap, isgreater than the mass of the striker K. Set-back therefore increases the distance between the'- percussion-capand striker-.
