Den Gegenstand vorliegender Erfindung bildet ein verbesserter, mit Transportsicherung versehener Doppelzünder für Schrapnels mit Tempirschlüssel. Eigenthümlich für diesen Zünder ist die in einem der Satzstücke angeordnete Sicherung, die in der Sicherungsstellung nicht allein den Zeit- und Aufschlagzünder gegen vorzeitige Zündung, sondern auch den Zünder gegen Drehung auf dem Geschofs sichert, während beim Entsichern der Zünder fertig gemacht und gleichzeitig freigegeben wird, so dafs er beim Abfeuern des Geschosses sich weiter in das Geschofs einschrauben kann und die Satzstücke fester gegen das Geschofs anpreist.The subject of the present invention is an improved one with a transport lock provided double fuse for shrapnel with tempir key. Strange for this detonator is the safety device arranged in one of the set pieces, which is in the safety position not only the time and impact detonator against premature ignition, but also the The detonator is secured against rotation on the projectile, while the detonator is used when the safety device is unlocked is made ready and released at the same time, so that when the projectile is fired, he himself can screw further into the storey and praises the set pieces more firmly against the storey.

Der vorliegende Zünder unterscheidet sich hinsichtlich seiner Wirkungsweise und Gesammtanordnung nicht wesentlich von bekannten Zündern, es sollen daher die Haupttheile desselben hier nur erwähnt werden. 11 ist der Zünderkörper, 40 und 41 sind die Satzstücke, von denen das erstere, 40, am Zünderkörper 11 festgekeilt oder sonstwie befestigt ist, während das letztere, 41, lose angebracht ist und nach beiden Richtungen gedreht werden kann. Der Zünderkörper 11 ist nicht unmittelbar in das Geschofs, sondern in eine Regulirungshülse 13 eingeschraubt, die wieder mittels Schraubengewinde und einer kleinen Stellschraube im Geschosse festgehalten wird. Der Zünderkörper μ ist, wie gewöhnlich, hohl ausgeführt und mit einemThe present detonator differs in terms of its mode of operation and overall arrangement not essentially of known detonators; therefore the main parts of the same should be considered only be mentioned here. 11 is the detonator body, 40 and 41 are the set pieces, of which the former, 40, is keyed to the detonator body 11 or otherwise attached, while the latter, 41, is loosely attached and after both Directions can be rotated. The detonator body 11 is not directly in the projectile, but screwed into a Regulirungshülse 13, which again by means of screw thread and a small adjusting screw is held in the projectile. The detonator body μ is how ordinary, hollow and with a

Boden 12 versehen. Innerhalb des Zünderkörpers sind die beiden Zünder angeordnet; und zwar schlägt der Hammer 16 mit seiner Nadel 17 auf die Zündpille 10 beim Aufschlag des Geschosses, während die hervorstehende Kante 19 einer am Hammerkörper 16 sitzenden Hülse 18 gegen die in dem Ring 1 5 sitzende Zündpille 20 des Zeitzünders wirkt.Floor 12 provided. The two detonators are arranged inside the detonator body; in fact the hammer 16 strikes with its needle 17 on the primer 10 when the projectile hits, while the protruding edge 19 of a sleeve 18 seated on the hammer body 16 acts against the squib 20 of the time fuse sitting in the ring 15.

Die den Erfindungsgegenstand bildende Anordnung ist nun die folgende:The arrangement forming the subject of the invention is now the following:

In einer Aussparung 29 an der unteren Seite des festen Satzstückes 40 ist ein unter Federwirkung stehender Sperrarm 21 (Fig. 3 bis 5) um den Zapfen 22 drehbar. Dieser Sperrarm ist mit drei Ansätzen 23, 26 und 28 versehen, von denen der Ansatz oder Sperrzahn 23 durch eine Aussparung 24 in der Seitenwand des Zünderkörpers in die Kammer 25 hineinragt. Seine Verticaldimension entspricht der Höhe dieser Kammer, d. h. dem Abstand der Unterkante des Ringes 15 von der Fufsscheibe des Hammers 16, so dafs die Theile 15 und 16 sich einander nicht nähern können und demzufolge gesichert werden, wenn der Sperrzahn in die Kammer hineinragt.In a recess 29 on the lower side of the fixed sentence piece 40 is a spring action upright locking arm 21 (FIGS. 3 to 5) rotatable about pin 22. This locking arm is provided with three approaches 23, 26 and 28, of which the approach or ratchet 23 through a recess 24 in the side wall of the detonator body protrudes into the chamber 25. Its vertical dimension corresponds to the height of this chamber, i.e. H. the distance from the lower edge of the ring 15 from the foot disk of the hammer 16, so that the parts 15 and 16 come together can not approach each other and are therefore secured when the ratchet in the Chamber protrudes.

Die Nase 26 ist an der unteren Seite des Sperrarmes 21 angeordnet und tritt, wenn der letztere seine Sperrstellung einnimmt (Fig. 3), in eine in der Regulirungshülse 13 vorgesehene Aussparung 27 ein und verhindert hierdurch das gegenseitige Drehen des Zünders und Geschosses. Der dritte Ansatz 28 ragt nach aufsen in die Aussparung 29 des Satzstückes, in welche die oben erwähnte Aussparung 27 ausmündet.The nose 26 is arranged on the lower side of the locking arm 21 and occurs when the the latter occupies its blocking position (Fig. 3), in a provided in the Regulirungshülse 13 Recess 27 and thereby prevents the fuse and projectile from rotating in relation to one another. The third approach 28 protrudes outward into the recess 29 of the sentence piece, in which the above-mentioned recess 27 opens out.

Die Wirkungsweise dieses Sperrarmes ist folgende:The mode of action of this locking arm is as follows:

Claims

When the detonator is inserted into the projectile, the locking arm takes the position shown in FIG Position, the parts being adjusted in such a way that the detonator body 11 is not completely in the the regulating sleeve 13 is screwed in when the nose 26 is in the recess 27 of the sleeve snaps into place.

When the sleeve is screwed into the projectile, the set washers are then used for Transport and tempering given suitable clamping, whereupon the adjusting screw of the sleeve is detected. When the detonator is tempered, an approach of the one described below occurs Tempirschlüssels into the recess 29, engages the lugs 28 and rotates thereby the locking arm 21, so that it moves from the position according to FIG. 3 to that according to FIG. at further rotation of the Tempirschlüssels sets piece 40 and igniter body 11, which is firmly connected to the latter, taken a short distance until the detonator is screwed tightly into the regulating sleeve, with the parts taking up a position as shown in FIG. The approach 26 is against the outside of the Put on regulating sleeve 13 and prevent the locking arm from returning to its original position.

As mentioned, the locking arm takes the detonator body with it when it rotates, whereby this is screwed more tightly to the storey (or the regulating sleeve) and the set pieces also better to be clamped. Another clamp and one more turn will take place when the projectile is fired, provided that the thread of the Part of it runs accordingly to the twist of the gun barrel.

Instead of using a regulating sleeve 13, the igniter can also be screwed directly into the projectile, in which case the set washers must be attached from above; to make this possible, above the upper set washer a screw ring to secure the washers is screwed on and by means of attached to a set screw.

The tempir key serves to temper the igniter and at the same time to accomplish it the release of the locking hook described above.

The temple key consists of two concentric rings 51 and 52, of which the the former is provided with a handle 50. The inner surfaces of these rings are the outer surfaces of the two sentences 40 and 41 adapted, and each with an approach 60 respectively. 61 provided. Of the Extension 61 is firmly attached to the ring 51 and corresponds to the recess 42 of the sentence piece 41, while the extension 60 so on a spring 62 arranged in a recess of the ring 52 is seated so that it can be moved radially remain. Are now the rings 51 and 52 prevented from their mutual rotation and the tempir key is placed on the igniter in such a way that the projection 61 enters the recess 42 of the sentence piece 41 engages, then when turning the Tempirschlüssels the approach 60, if he reaches the recess 29, jump into it, then with further rotation of the key rotate the locking arm 21, whereupon a further rotation of the set piece 41 opposite the sentence piece 40 is prevented.

The tempir key is provided with a device which serves to open the mutual The position of the rings 5 1 and 52 can be changed as desired. This device consists of a screw 53, which engages in a toothing 54 of the ring 52. A pressure pin 55 acts against one Locking spring 56, the toothing 57 of which engages in a gear 58 seated on the screw spindle, so that the latter can only be rotated when the pin 55 triggers the Spring 56 has caused. The ring 52 is displaceable with a scale and the ring 51 with a arranged pointer 59 is provided.

It can be seen that with this device the mutual angular distance between the two lugs 60,61 changed at will and thereby determined the magnitude of the rotation given to the clauses can be.

Since the pointer 59 attached to the ring 51 is shiftable, the zero point of the Tempirscale can be shifted, and it will be, therefore Easily possible, corrections concerning the difference in temperature and attachment, to relocate to the tempir key. .

With the described double igniter and tempir key, the tempirening should be done in high Degrees simplified and at the same time can be carried out more precisely and faster. Since the Correction as to the difference between attachment and temperature (as stated above) Can be relocated to the scale for the pointer of the key, not only the special one No indication of the tempir distance, but one is simultaneously through the setting of the key can control the temperature of the last shot fired.
