Description

Die Erfindung betrifft eine Manipulierpatrone mit einer Patronenhülse, die einen Hülsenboden, eine zylindrische Wand, einen Hülsen-Schulterkonus und einen Hülsenmund aufweist und mit einem Manipulierkörper, der sich auf dem Hülsenboden abstützt und der einerseits am Hülsenboden und andererseits am Hülsenmund befestigt ist.The invention relates to a manipulation cartridge with a cartridge case which has a case base, a cylindrical wall, a case shoulder cone and a case mouth and with a manipulating body which is supported on the case base and which is fastened on the one hand to the case base and on the other hand to the case mouth.

Bei bekannten Manipulierpatronen dieser Art (siehe US-A-2 342 549 und 2 882 821) ist durch die Befestigung des Manipulierkörpers am Hülsenboden der Schwerpunkt der Manipulierpatrone gegenüber den scharfen Patronen verlagert, wodurch die Zufuhr der Patronen zur Waffe beeinflusst wird, was unerwünscht ist, da sich die Manipulierpatronen wie die scharfe Munition verhalten sollten.In known manipulation cartridges of this type (see US Pat. Nos. 2,342,549 and 2,882,821), the center of gravity of the manipulation cartridge is shifted from the sharp cartridges due to the attachment of the manipulation body to the base of the sleeve, which affects the supply of the cartridges to the weapon, which is undesirable , because the manipulation cartridges should behave like live ammunition.

Durch die Erfindung wird die Aufgabe gelöst, die Manipulierpatrone, welche gegen die Kräfte, die beim Zuführen der Patrone zu einer Waffe auftreten widerstandsfähig sein muss, so auszubilden, dass der Schwerpunkt sich am richtigen Ort befindet, obwohl durch die Befestigung des Manipulierkörpers am Hülsenboden eine Schwerpunktverlagerung auftritt.By the invention the object is achieved, the manipulation cartridge, which must be resistant to the forces that occur when feeding the cartridge to a weapon, so that the center of gravity is in the right place, although by attaching the manipulation body to the base of the sleeve Shift in center of gravity occurs.

Die Erfindung bezieht sich auf eine Manipulierpatrone mit einem Manipulierkörper der einen zylindrischen Hohlraum aufweist. Die vorstehende Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Hohlraum in seinem vorderen Teil einen verstellbar eingeschraubten Trimmkörper enthält, um den Schwerpunkt der Manipulierpatrone in die gewünschte Lage zu bringen.The invention relates to a manipulation cartridge with a manipulation body which has a cylindrical cavity. The above object is achieved according to the invention in that the cavity contains an adjustable screwed-in trim body in its front part in order to bring the center of gravity of the manipulation cartridge into the desired position.

Durch diesen Trimmkörper wird erreicht, dass sich die Manipulierpatrone wie scharfe Munition verhält.This trim body ensures that the manipulation cartridge behaves like live ammunition.

Ein Ausführungsbeispiel der erfindungsgemässen Manipulierpatrone ist im folgenden anhand der beigefügten Zeichnung ausführlich beschrieben.An embodiment of the manipulation cartridge according to the invention is described in detail below with reference to the accompanying drawing.

Die einzige Figur der Zeichnung zeigt einen Längsschnitt durch eine Manipulierpatrone.The only figure in the drawing shows a longitudinal section through a manipulation cartridge.

Gemäss dieser Figur weist die Manipulierpatrone 10 einen Manipulierkörper 11 und eine Patronenhülse 12 auf. Die Patronenhülse 12 weist einen Hülsenboden 13, eine Hülsenwand 14, einen Hülsen-Schulterkonus 15 und einen Hülsenmund 16 auf. Der Manipulierkörper 11 besitzt einen zylindrischen Hohlraum 17, in dem sich ein sogenannter Trimmkörper 18 befindet, der durch eine erste Schraube 19 im vorderen Teil des Hohlraumes 17 gehalten ist. Durch eine zweite Schraube 20 ist der Manipulierkörper 11 im Hülsenboden 13 befestigt. Durch den Trimmkörper 18 wird erreicht, dass der Schwerpunkt der Manipulierpatrone 10 sich an derselben Stelle befindet, wie der Schwerpunkt einer scharfen Patrone.According to this figure, the manipulation cartridge 10 has a manipulation body 11 and a cartridge case 12. The cartridge case 12 has a case base 13, a case wall 14, a case shoulder cone 15 and a case mouth 16. The manipulator body 11 has a cylindrical cavity 17 in which there is a so-called trim body 18 which is held in the front part of the cavity 17 by a first screw 19. The manipulation body 11 is fastened in the sleeve base 13 by a second screw 20. The trim body 18 ensures that the center of gravity of the manipulation cartridge 10 is at the same location as the center of gravity of a sharp cartridge.

Diese Manipulierpatrone 10 weist eine Giessmasse 22 auf, die sich zwischen dem Hülsen-Schulterkonus 15 und dem Manipulierkörper 11 befindet. Diese Giessmasse 22 dient dazu, ein übermässiges Stauchen des Hülsen-Schulterkonus zu verhindern. Eine Manipulierpatrone soll mehrmals verwendbar sein. Wenn die Patronenhülse 12 der Manipulierpatrone beim Zuführen zu einer Waffe und beim Ausstossen aus der Waffe stark defomiert wird, insbesondere, wenn der Hülsen-Schulterkonus stark bestaucht wird, dann ist die Manipulierpatrone nicht mehr verwenbar, da dann ein zuverlässiges Zuführen und Ausstossen der Manipulierpatrone aus der Feuerwaffe nicht mehr gewährleistet ist.This manipulation cartridge 10 has a casting compound 22 which is located between the sleeve-shoulder cone 15 and the manipulation body 11. This casting compound 22 serves to prevent excessive compression of the sleeve-shoulder cone. A manipulation cartridge should be usable several times. If the cartridge case 12 of the manipulation cartridge is severely deformed when it is fed to a weapon and when it is ejected from the weapon, in particular if the sleeve-shoulder cone is heavily compressed, then the manipulation cartridge can no longer be used, since then the manipulation cartridge can be reliably fed and ejected the firearm is no longer guaranteed.

Durch das Einfüllen der Giessmasse 22 zwischen den Hülsen-Schulterkonus 15 und den Manipulierkörper wird zwar anfänglich ein Stauchen nicht verhindert, aber es ist so klein, dass die Manipulierpatrone verwendbar bleibt. Die Giessmasse verhindert, dass die Stauchung der Patronenhülse 12 einen gewissen Wert übersteigt.Filling the casting compound 22 between the sleeve shoulder cone 15 and the manipulation body does not initially prevent compression, but it is so small that the manipulation cartridge can still be used. The casting compound prevents the compression of the cartridge case 12 from exceeding a certain value.
