PATENT OFFICE.

The present invention relates to an impact or double detonator in which the Ignition device (percussion cap) of the impact ignition and thus the explosive charge of the projectile depending on the setting of the detonator either immediately upon bullet impact or as a result of intended mechanical Delay only after the projectile has penetrated the target for the purpose of production a mine effect is ignited. Of the known detonators with a delay that can be switched off and on, where for the same purpose between the detonating mass and the explosive charge of the projectile according to Art the known combustion igniter acting on and off delay set arranged is, the present invention differs in that to achieve a Mine action a delay in the ignition of the primer takes place, including in the manner of the known mechanical or hydraulic time fuse-acting organs are provided, depending on the intended Effect of the impact ignition before the shot in the known way with the hand or with a key after certain brands or brand lines with or set without delay resp. switched off or on.

The essence of the invention consists in a change in position, or input and Switching off, or switching on and replacing any igniter parts to be operated inhibiting device to be arranged in the igniter, which the ignition organs - usually a primer and needle - like this in the case of delayed ignition hold apart for a long time until the projectile has penetrated a certain distance into the target is, and that only then the ignition organs z. B. by flying against each other, thrust, blow, Friction or other, possibly electrical excitation, the delayed ignition cause. The escapement device is of course switched off if the projectile detonates immediately upon striking the target target.

The delay or jamming devices can be used for the same purpose be of various kinds.

The free path of the ignition organs from each other can be changed by changing the position of any igniter parts be dimensioned so long that there is a delay in the ignition compared to the instantaneous ignition.

The ignition organs, which are mostly under spring pressure or leverage, can through Gear drives, clockworks, fluid escapements and others, especially in the case of mechanical ones Time detonators already used and applicable devices are influenced in such a way that that the force, especially the spring force, after a certain, previously set Time after the projectile impact is triggered and the ignition organs come into effect in a known manner.

It can also be arranged hammer-like or striker-like acting clubs that through the projectile impact

the energy of forward sliding or otherwise moved detonator parts are actuated and that Primers ignite by the hitting power of this bat, which of course is a delay the ignition has in the wake of the time required to move the bat from the state of rest to put; furthermore, the delay depends on the distances to be covered by the individual Fuse parts. This delay is a fraction of Se- ■ announce the time during which the projectile penetrates deeper into the target before it detonates is brought.

In the drawing, for example, without exhausting the concept of the invention, various Embodiments of the present invention shown, with almost all other parts belonging to the detonators in In the interests of simplification have been omitted. Let it be noted here that these embodiments can also be built into all double fuses.

Fig. Ι shows a detonator with a long needle α and a short needle b, which are arranged in one or opposite a rotatable or adjustable part, here in the needle piece c , that either the long needle α is above the primer d , with When the bullet hits the short path between primer d and needle a, an instant ignition takes place, or the short needle b is set opposite the primer d and thus the path between primer d and needle b is lengthened, so that in connection with the movement of the corresponding fuse parts There is a corresponding delay in ignition and the projectile can penetrate the target before it detonates. The needle intended for delayed ignition can also be held a little blunt, so that the primer should ignite a little more slowly. When the targets are fired with delayed fuses, the final velocity of the projectile as it penetrates deeper into the target is suddenly reduced so much that the fuse parts that slide forward due to their persistence retain a significant amount of energy, which in any case, in spite of some resistance, is ignition of the primer. Fig. 2 shows the detonator from above with the marks "ο" and "1".

It goes without saying that a needle can also be used in place of the two needles of different lengths or the firing pin can be arranged displaceably in the longitudinal direction of the igniter, so that these two parts by turning or adjusting a screw spindle ο. like. on a certain distance from each other can be set to get an instant or to achieve delayed ignition.

Fig. 3 shows a detonator in which the firing pin e, which flies forward when the projectile hits, is inhibited in its forward sliding by sliding on a steep screw f , whereby it has to make a further path due to the thread of the screw / before the primer g is pierced and ignited by the needle h. Depending on the setting of the screw f , the bolt e shifts on the screw f in such a way that it has to make a shorter or longer path when the projectile impacts and the ignition takes place sooner or later.

Fig. 4 shows a fuse of the type described above, in which the firing pin i automatically fires back when fired, and assumes the same position as the firing pin e in Fig. 3 when it is released by the actuator k for delayed ignition. While the bolt i in the position of the individual parts shown hits the needle m directly with the primer Z when the projectile hits and ignites, it must with delayed ignition the path made backwards during the shot as with the device according to FIG. 3 from the rear position make forward again. The adjusting piece k engages through the detonator head in a partially closed groove of the bolt i at the front and is cut away halfway in a known manner at the engagement end. By turning the adjusting piece k , its end comes out of engagement with the bolt i, so that it can slide back in the above-mentioned manner when the shot is fired.

Fig. 5 shows an igniter in which two needles η and 0 are provided. If the eccentrically arranged needle n is above the primer p , as shown, it will be ignited immediately when the bullet hits. If this needle η is adjusted so that it faces a free hole in the firing pin q , the firing pin q slides forward when the projectile hits, compresses the spring s and, due to the positive guidance q _l , rotates in such a way that it passes through with the primer ρ the spring s can be thrown back against the needle 0, whereby the primer \ is ignited with a delay corresponding to h these movements. So that the firing pin q with the primer ρ is not thrown against the rear needle 0 when the shot is fired, the firing pin rests with shoulders on the shoulders of the ground screw i. At the

Forward sliding of the firing pin q come due to the inevitable guidance q ₁ the shoulders of the firing pin and ground screw in such a way that when the firing pin q is thrown back by the spring s, the primer ρ can hit the rear needle ο.

6 and 7 show further forms of the detonator according to FIG. 5. In FIG. 6, the needle u is arranged so as to be radially displaceable and sits next to the primer v until the bullet hits. If the firing pin with the primer ν flies forwards when the projectile hits, the spring U ₁ pushes the needle u into the axis of the primer v in such a way that when it is thrown back by a spring or the like, it flies against the needle u and with one of these Movements corresponding delay is ignited. In

7, the needle w is rotatably arranged for the same purpose and is rotated into the axis of the primer cap X ₁ by the spiral spring W ₁ after the firing pin χ has slid forward.

In Figs. 5, 6 and 7 two needles are provided. The back needle can also omit and a front needle can be arranged so that it can be adjusted so that it is when the bullet hits the ignition element does not hit, the ignition bolt flies back again as a result of the elastic shock and as a result of the action of another elastic means again and in the meantime meets itself automatically Influence of moving ignition organs switched off and in the axis of the primer cap set needle, the ignition being delayed by a time corresponding to these movements will.

FIGS. 8 and 9 show an igniter is held in the delay in setting up the firing pin \ with the locking arm ^ _1, ^ ₂ swings about as long (Fig. 8) until the ignition tube. Ci ₁ (Fig. 9) has flown forward when the projectile impacts and through. 45 Serving on the shorter part of the locking arm that has pressed with its longer part to the outside, such that the firing pin is \ free and by the force of the tensioned during the forward sliding of the ignition sleeve U ₁ spring b _x with its primer C ₁ against the needle ά _{Ύ is} thrown, the primer igniting with a delay corresponding to these movements.

The switching on and off of the locking arm ^ ₁ (Fig. 8) is done by turning the needle piece e _x , in which the locking arm ^ ₁ is attached swinging at ^ _1. The short part of the locking arm ^ ₁ is inevitably guided in an inclined groove f _{x of} the detonator housing, so that when you turn the needle piece e _v the short part of the locking arm ^ ₁ in the longitudinal direction of the detonator and the longer arm of the locking arm Z ₁ from the outside is moved inside and vice versa so that it engages as shown in Fig. 8 on the firing pin \ and it holds. At f _x in Fig. 9, the said groove in the detonator housing is after such a recessed front that, when a stroke by the forward sliding sleeve a _x on the short portion of the locking arm ^ ₁ it enters into the recess at _ / j during this case the longer part of the barrier arm swings outwardly (Fig. 9) and releases the firing pin \.

Fig. 10 shows a detonator in which the 'needle bolt ^ ₁ with the web Zr ₁ flies forward when the bullet hits and punctures the primer Z ₁ , which can be reinforced by its explosive power, which can be reinforced by a small powder charge arranged behind it g needle _x bolt back spin, the web Zz by bent back ₁ and the primer is ignited I ₁ with a corresponding delay with the rear needle Ar. ₁

If the detonator is to act without delay, the ignition bolt W _{1 is} released in a known manner by adjusting the adjusting sleeve Tn _{1, in that the shoulders O 1 of} the adjusting sleeve WJ ₁ come to rest over corresponding cutouts in the ignition bolt Ti ₁ . The firing pin W ₁ then immediately flies forward against the needle k ₁ when the projectile hits the ground and ignites the explosive charge of the projectile without delay. The web Ji ₁ remains in the annular groove and cannot move forward when the bullet hits the ground.

Instead of the deflecting web H ₁ , other means can also be provided which release the needle bolt g _x for its backward movement after the forward movement has taken place.
