The invention relates to maneuvering cartridges for guns, especially larger guns Caliber.

In the case of maneuvering cartridges, a distinction is made between sleeve and sleeve-less cartridges. The latter wise has a number of advantages over sleeve cartridges. That’s how they are, there’s no empties with them accrues, pure disposable cartridges, which are distinguished by their light weight as well as by a low Mark space requirements. Furthermore, there is no need to recondition the cartridge cases. Overall it results thus a drastic connection to the sleeve cartridges.

However, these advantages are offset by a number of disadvantages, especially the inadequate one Stability of the more or less bulging powder bag, which makes the loading process on the gun does not go so quickly and smoothly. Even the damnation necessary to achieve the sharp Shot imitated muzzle bang is required, leaves something to be desired with the caseless cartridge left over. The one used as a dam, attached to the powder bag by gluing or other means Plug of cork powder or the like should either be supported inside the gun barrel or but be so massive that a reasonably effective damnation on the basis of it Inertia is achievable. There is, however, the risk that by inadequate dismantling of the massive plug, individual fragments fly out of the gun barrel so far that they Can cause damage to people and material.

It is known to use a foam plastic plug instead of a plug made of a cork mass flexible and easily compressible material as a dam for the propellant charge of a recoil-free To use guns. But this condemnation is not something that can be dismantled Damnation. If you wanted to use this plastic as a dam for a caseless cartridge, so, if at all, the damming agent would only produce a very weak one Firing bang and only incompletely dismantled.

The invention is based on the object of avoiding these disadvantages, a maneuvering cartridge to create that with a comparatively small powder charge a loud, similar to the sharp shot Bang results; which also enables the gun to be loaded quickly and properly and that there are no residues after firing in the maneuvering cartridge for guns

¹ S pipe remains, fragments that cannot be dismantled reach far in front of the mouth of the pipe.

According to the invention, the object is achieved in that one in a known manner in a bag located powder charge as well as one in the diameter

^ao at least the caliber of the launch tube corresponding damming in a hollow cylinder consisting of a flame-retardant plastic that disintegrates when fired, for example foamed polystyrene, are arranged at a distance from one another and attached to the wall of the hollow cylinder.

The maneuvering cartridge according to the invention can be loaded in a simple manner like a normal cartridge case will. The hot powder gases produced during the shot melt and disintegrate the hollow cylinder almost residue-free. Small residues that remain in a flaky state are also removed the damming that crumbles when leaving the pipe.

The maneuver cartridge according to the invention is also advantageous in training the troops by loading takes place similar to a battle. It is also advantageous that the maneuvering ammunition in the existing Holding devices of the weapons or the combat equipment can be accommodated without changes to do this.

To maintain an expansion space of the same size for the powder charge can in an advantageous embodiment of the invention between the powder charge and the damming be arranged from the material of the hollow cylinder existing spacer.

the intended use appear particularly suitable. The specifically extremely light material is flame retardant, but melts and disintegrates almost completely when the shot is fired, so that no undesirable side effects occur when the powder charge burns off. In the front part of the sleeve a damming plug 2 is provided, which advantageously, according to an older proposal by the inventor, consists of a non-preformed, paste-like mixture of filler, a synthetic resin and a hardening binder, which mixture hardens to a damming plug without post-treatment and adheres to the cylinder wall The diameter of the dam is at least equal to the caliber, preferably slightly larger, which improves the bang effect and promotes the destruction of the dam. A propellant charge 4 located in a cartridge bag 3 is inserted into the other end of the hollow cylinder and is attached to the cylinder wall by gluing, for example with water glass. 5 with a firing charge is referred to, which is attached to the cartridge pouch. To maintain a combustion chamber for the propellant charge, a spacer 6 made of the material of the cylinder is inserted between the dam and the powder charge. The spacer consists of two webs 6 a and 6 b assembled at right angles to form a cross, which, like the hollow cylinder, disintegrate when fired. Patent claims: 1. Maneuver cartridge for guns, characterized in that a known manner in a bag (3) located powder charge (4) and a diameter at least the caliber of the launch tube corresponding dam (2) in one of a flame retardant, when shot in itself disintegrating plastic, for example foamed polystyrene, existing hollow cylinder (1) are arranged at a distance from one another and attached to the wall of the hollow cylinder (1) . 2. Maneuver cartridge according to claim 1, characterized in that between the powder charge (4) and the dam (2) a spacer made of the material of the hollow cylinder zo piece (6) is arranged. 3. Maneuver cartridge according to claim 2, characterized in that the spacer (6) consists of webs (6 a and 6 b) assembled to form a cross. Considered publications:
