is used.

The invention relates to an engaging and disengaging delay for all projectiles Type and differs from devices of a similar type in that the Projectile works with or without ignition delay on impact, depending on the case as desired without it being necessary to do anything on the projectile or the detonator change or move.

The invention is of particular importance in the case of projectiles with base fuses, for which so far no reliable detonator with before

determinable sensitivity existed, since any seal of the deformable plate, through which the detonator is supposed to be accessible was unreliable.

The essence of the invention is that in the fuse or in the projectile a free stored and freely movable body, depending on the position in which the Projectile was loaded into the gun, ίο such a situation by gravity, Impact, centrifugal force or some other force that the detonator assumes either with delay or works without delay.

For this purpose the projectile or the detonator is on its circumference or on the ground provided with a mark, such as. B. in Fig. I, attached to the floor of the projectile and has the shape of an arrow. Now the projectile with the arrowhead is following loaded in the top of the gun, the detonator works with a delay, and vice versa. One Such a design offers great advantages, which are that the detonator from the outside need not be accessible, and that the gun without the use of special instruments can be charged quickly.

The body freely stored in the projectile that causes the ignition delay or the same prevented, can act either directly or indirectly as a relay.

The object of the invention is shown schematically in Figs. 2 and 3 of the drawing and Fig. 2 shows one embodiment of the subject matter of the invention, while Fig. 3 shows another embodiment.

In the actual igniter, a body 10 is arranged which contains the device for regulating the sensitivity of the igniter. A cavity 14 and channels 1 and 4 are present in the body 10. Channel 1 leads to the actual ignition device of the detonator and channel 4 to the detonator or the explosive charge of the projectile. The part causing the ignition delay is mounted in the cavity 14 so that it can move freely and, as shown in FIG. 2, it can be a prismatic body 5. This prism 5 is provided with a channel 2 and an incendiary device 3. Will ^: now the floor z. B. with the mark upwards (Fig. R) introduced into the gun, the prism 5 will assume the position shown in Fig. 2 due to the effect of gravity. The whole arrangement is to be ^{imagined rotated by 90 °} to the left. Channels 1 and 4 are directly connected by channel 2 and, in the event of a projectile hitting, the jet flame from the detonator (not shown) can be led directly to the detonator or the explosive charge of the projectile. The detonator therefore works without delay. So that the body 5 securely retains its position once it is fired and during the flight of the projectile, special security bodies 6, 7 are arranged above the prism 5, which are held in their rest position by thin, flexible sheet metal cylinders 13. At the moment of firing, the safety bodies 6, 7 will remain behind due to their ability to persist against the projectile, bend open the flanged edge of the safety cylinder 13 and come to rest in the part of the space 14 left free by the prism 5, whereby a lateral movement of this prism after the Firing of the projectile is prevented. In the illustrated position of the prism 5, the securing body 6 drawn as a cylinder will come to rest in the free part of the space 14, while the securing cylinder 7 will be supported on the prism 5. If the detonator is now to work with delay, the projectile is inserted into the gun barrel with the mark pointing downwards and the prism 5 moves to the right from the position shown in Fig. 2 due to the effect of gravity and the incendiary device 3 between channels 1 and 4 come to rest, which causes the ignition delay. The prism 5 is secured against displacement in a manner similar to that described earlier by the securing cylinder 7.

The body S, which has a prismatic shape according to Fig. 2, but can also assume any other shape, such as. B. the shape of a ball 8, as shown in FIG. In Fig. 3, the ball 8 is again freely movable in space 14.- In the position shown, the incendiary device 3 10a is switched on between the channels 1 and 4 -and the detonator works with ignition delay, since the bolt Q ₁ is controlled by a spring 11 is held in its rest position, when the projectile is fired, is supported on the ball 8 and the channel 12, which connects the channels 1 and 4 directly, closes off.

As can be seen from the drawing, the bolt axis does not go through the center of the ball, but at a point between 11.0 of the center of the sphere and the fuse axis. This ensures that when the bolt is fired something is pressed into the space 14 and is supported eccentrically on the ball and holds it in place because the Bolt 9 is still out in its camp. The sphere therefore acts in the manner of a Relay.

If the projectile is now inserted into the barrel of the gun in such a way that the ball 8 comes to lie in front of the primer 3 due to the effect of gravity, then at the moment

of the firing of the bolts 9 due to the persistence in the space 14 drifted and the channel 12 is released so that the flame of the primer unhindered over the channels i, 12 and 4 get to the detonator or explosive charge of the projectile.

It goes without saying that the detonator can also be designed so that it can be fired of the bolt 9, the ignition delay can be switched on, while direct ignition is possible in the rest position will. The movement of the bolt 9 can also be caused by other forces, such as, for. B. centrifugal force and the like. You can also close or open the channels or switch on the delay be carried out in the most varied of ways without affecting the essence of the invention will be changed. Furthermore, the invention can be used to trigger another effect, e.g. B. the fact that the projectile acts as a tempered grenade, shrapnel or the like.

Claims (6)

Patent claims: 1st floor with retardation that can be engaged and disengaged, characterized in that that there is a freely supported body in the fuse or in the projectile, depending on the position of the projectile in which this is loaded into the gun, by the action of any external or internal forces assumes such a position before the projectile is fired that the detonator with or without ignition delay is working. 2. Projectile according to claim 1, characterized in that the with the transfer the pilot flame serving channels and movable body directly as a guide for the Pilot flame is used and, due to its location, the type of ignition or the type of use of the projectile (as a tempered projectile or as a projectile for impact). 3. Projectile according to claim 1 and 2, characterized in that the freely movable Body also serves as a closure member and depending on its location when loading the projectile before launching the same the opening or closing of the for the immediate pilot flame transmission serving channel causes. 4. Projectile according to claim 1 to 3, characterized in that the direct Ignition or ignition delay or some other effect of the projectile causing Body is designed as a prism (5) that moves freely in a space (14) of the igniter and with a Connection channel (2) for direct ignition and an incendiary device (3) for delayed ignition is provided, each Depending on the position of the projectile, the channel (2) or the primer (3) to coincide with the channels due to the effect of gravity (1, 4) of the detonator is brought. 5. Projectile according to claim 1 to 4, characterized in that the direct Ignition or ignition delay or some other effect of the projectile causing Body is designed as a freely movable ball (8) in the storage room, the depending on their location in space (14) either the firing of the locking bolt (9) and thus the release of the direct connection channel (12) between the Channels (1 and 4) prevented and the primer (3) to put into action or the firing of the bolt (9) and thus enables direct ignition. 6.
