Definitions

  • the timing is adjusted automatically by using the own weight of the projectile itself (or of the cartridge) placed in the machine.
  • I Fig; 1 is a longitudinal section of the machine according to the line I-I in Fig. with a projectile placed in the machine at the beginning of the automatic adjustment of the 3 timing.
  • Fig. 5 is a cross section along the line II'II of Fig. 3.
  • Fig. 6 shows the device for adjusting the timing mechanism.
  • Fi g. 7 isa perpendicular section to the view of Fig. 4.
  • capZ In thezero position of the fusethese I two notches a and a (Fig. 1) must both lie in For timing the fuse in the machine it is necessary to provide a notch a in the body of the fuse Z and a notch (1 in the rotatable fuse a plane including the axis of the projectile.
  • the two studs b and b. are arranged in the timing machine to correspond with the notches stand a If now the projectile is put into the adjustment socket (Z of the machine,
  • the case 6 is then still in the position drawn in dot-and-dash lines in Fig. 1 and is kept by itsouter screwthreading in the corresponding inner screwthreading of the adjustment socket d.
  • the screwthreading has a pitch of
  • the adjustment case 6 now sinks under the influence of the weight of the projectile, and moreover is brought into rotation by the screwthreading 6 If now the projectile has sunk so far that the disc 9 which is below the adjustment case is arrested, the adjustment case e has left the threading of the adjustment socket d and now continues its way on the ballbearing k carrying the projectile G until the studs 6 and b spring into the notches a and a due to the action of the springs f and i The stud 5 now leaves the bore 0 of the casing G so that the projectile further falls down by its own weight (Fig.
  • the adjustment socket d with the stud b is guided along a straight path by the keygroove h, the adjustment member 61 with the stud (1 being rotated while sinking by means of the screwthread of a nut fixed in the casing. By this the fuse cap is adjusted and at the same time the spring f is tensioned.
  • the handle a may be used and may be timed according to the scale T shown in Figs. 1-3 and indicating seconds or distances. If the fire is controlled centrally, the. timing may be indicated in the way shown in Fig. 6 on a dial apparatus, from which it may be transmitted into the adjustment machine by adj usting the hand and the handle 12. Furthermore I adjustment -more the machin may be adjusted directly on the desired timing by mechanically or electrically causing the shaft 1" to rotate from the central fire control station.
  • the embodiment shown in'the drawings possesses two adjustment sockets so that two projectilesmay be dealt with simultaneously but independentlyof each other. It is of coursepossible to provide themachine with sockets.
  • a machine for adjusting the timing of a fuse comprising in combination a housing with one or more adjusting bores adapted to receive the projectiles which are to be timed; an adjusting cup in each bore; each cup being shiftably arranged by means of a key and groove; a spring-pressed stud in each cup; said cup serving to maintain the inserted projectiles in vertical position; an adjusting socket in each cup ;'a rotatably and shiftably mounted adjusting element having aspring actuated.
