Definitions

  • This fuse operates by the carriage being driven into the body of the fuse on contact with an obstacle offering even a slight resistance, the driving in of the movable carriage being rendered possible by the putting out of action of a device which fixes the said carriage before impact with the obstacle. Firing is effected by inertia, due to the con tinuation of the movement of the projectile and the percussion cap, the latter coming into contact with the striker which, together with the casing of the carriage undergoes a relative displacement in regard to the projectile.
  • the device for fixing the carriage before impact with the obstacle is constituted, in a large number of constructional forms described, by a pin passing through the head of the carriage.
  • the aforementioned specification No..1,562,054 discloses the use of an extremely light carriage, the fixing device being constituted by a plastic or resilient material, such as felt or cork. against which the head of the moving carriage is adapted to bear.
  • the present invention enables an extremely sensitive fuse of the type described in the aforementioned specification No. 1,562,054 to be constructed, while at the same time obviating the disadvantages enumerated in the foregoing.
  • the invention consists in the combination of an extremely light carriage with a retaining device which, while being effective, is of relatively small strength, the mutual arrangement of the carriage and the retaining or fixing device being such that the arrangement as a whole offers every security, despite the low strength of the elements. while constituting a perfect means of absorbing or damping the effects of any untimely recoil of the percussion cap.
  • the movable carriage is provided with a support, which,
  • the cup may be employed for retaining the carriage and for supporting the percussion cap in two different ways, the pin-fixed cup either forming a simple support for the. carriage, in. which case it is located outside the carriage under the bottom of the casing, or the cup being arranged within the-carriage between the. bottom of the carriage and the percussion cap, the pin or pins associated with the cup then passing not merely through the cup it, self, but also through the walls; of the carriage casing.
  • V Figure 1 is a sectional elevation of a fuse body provided with the percussion device according to the invention in, which, the system of pin-fixed cup is arranged entirely outside the movable carriage, the cup forming a support for the bottom of the carriage casing,
  • Figure 2 is a plan view of the washer retaining means it in Figure 1;
  • Figure 3 is a side elevation in a section of Figure 2;
  • Figure 4 is a plan of a modification of the carriage guiding and, retaining device in front of the percussion cap.
  • Figure 5' shows in sectional elevation a constructional form wherein the cup is lodged within the carriage casing and forms a direct support for the percussion cap, the pin associated with the cup fastening the latter, and the casing at the same time, to the fuse body.
  • n denotes the principal element of a fuse body in which is mounted the movable carriage constituted by a casing Z) expanded atits front end and set on the expanded head, 0 of a striker 00
  • the longitudinal walls of the said casing 6 are pierced in known manner by openings Z1
  • the carriage casing 72 is supported on a cup 6' which is pierced by a central orifice e and is fastened to the fuse body at by a pin g.
  • the bottom 6 of the casing rests directly on the bottom of the cup, and the percussion cap 1", on its recoil path, thus meets the said bottom 6 and the cup 6, which latter is supported on the pin 9.
  • the percussion device is completed by a washer h comprising tongues h which, by
  • the washer is held between the front face pin g. It follows that there is. no longer 1 any necessity to make the carriage casing of a strength which alone is capable of retain.- ing the percussion; cap. On the contrary, the device described, no support being required for the head. of the carriage and the expanded end of the striker, the carriage head and also the striker may be made extremelylight. V
  • a washer 8' of small diameter with two wings Ti having the same action as the tongues 71 in Figures 2 and 3 may be used in the manner disclosed in the prior specifications referred to hereinbefore.
  • the cup 6 is located at the bottom of the carriage casing b so that the percussion cap. f is supported on the bottom of the said cup which in turn is supported on the bottom 6 of the casing.
  • the pin 9 passes altogether through the longitudinal walls of the cup and casing.
  • the entire percussion device that is to say the movable carriage Z)0fh, may be removed by unscrewing the detachable fuse cap a
  • this constructional form is, in some respects, preferable to that shown in Figure 5, wherein, however, the removal of the fuse cap a allows of the examination and inspection of the principal elements of the percussion device.
  • a projectile fuse of the type having a carriage movably mounted within the fuse body and relatively movable striker and detonator elements carried thereby, means for preventing premature movement of said carriage and said elements to detonating position comprising a supporting member mounted within said fused body coaxially and in supporting engagement with said carriage, and yieldable means for retaining said supporting member in a fixed position with re spect to said fuse body until exploding impact of said projectile.
  • a projectile fuse of the type having a carriage movably mounted within the fuse body and relatively movable striker and detonator elements carried thereby, means for preventing premature movement of said car riage and said elements to detonating position comprising a cup-shaped member mounted within said fuse body coaxially and in supporting engagement with said carriage and having a flame transmitting opening therein, and yieldable means for retaining said cup-shaped member in a fixed position with respect to said fuse body until exploding impact of said projectile.
