Definitions

  • the present invention has as its aim the resolution of the above mentioned problems by means of a new and perfected arrangement of the percussion masses and of their holders, together with a suitable arrangement of the safety device.
  • Fig. 1 is an axial section of the head of the aforesaid bomb provided with a fuse according to the present invention and with a safety device having two shells (segments).
  • Fig. 2 is a front view of the said device.
  • Figs. 3-5 represent the front view of various other similar devices fashioned differently.
  • the body of the bomb 1 containing the explosive charge has the neck 2 and the head 3 shaped suitably to allow the fuse to be adjusted thereoh?

  • the fuse device consists of two discs 8, 9 provided withtubularstems 8, 9 onesliding'in the other, and forming the axial guide of a helical spring 10 suitablefor keeping the discs apart.
  • plosive is provided with a'striker l1, and disc9 carries thedetonating charge enclosed in its tubular stemT'Q.
  • a slide '13 mounted to slide transversely in the'cowl 4 and guided Disc 8,-ahle to hold an exbetween disc 8 and stem 9, prevents any movement of approach'between striker and detonator.
  • the slide is connected with a device suitable to control its withdrawal to be described later.
  • the two discs 8, 9 rest against two half-spheres 8", 9, consisting essentially of a heavy, easily fusible, material, which may contain explosive charges 8, 9.
  • These'half spheres can roll or slide over theinternal surfaces of the semi-ovoidal portion 5 and of the curved base 7 the respective radii of curvature are so chosen that any movement of the half spheres, whether a rolling or agslidingmovement, will correspondto a-.forced neutral approach of the two discs 8-9, forced'by the aforesaid halfspheres. But these movements are not possibleso longas the' slide13 is in position.
