Description

The invention relates to the manufacture of an exercise cartridge with a part made of synthetic material and a metallic, normal outer sleeve, i.e. a sleeve that is identical to the sleeves used on rifles, machine guns, pistols and the like. can be used for a sharp shot.

The invention aims to provide such a cartridge with all the advantages the precision of the caliber, the thermal resistance, the sliding ability during loading and ejection after the shot and in this way to facilitate the insertion in belts, as well as the firing of automatic weapons in general, with protrusions of any kind at the exit of the shot and an escape η of gas can be avoided.

The invention is characterized by means that both overall and can also be used separately and in particular by means of a metallic sleeve that has a resistance, which is the same as that for live cartridges for the accuracy of the pages, the resistance and the insensitivity against temperature fluctuations is provided, whereby the insertion into belts or loaders and an automatic expulsion is made possible. This sleeve is inserted inside a sleeve made of synthetic material of uniform thickness, which has an outer part that forms the ball. The whole thing serves the purpose, an instantaneous one when a shot is fired Merging and charring of an upper section, whereby the discharge of the gas produced by the ignition of the Powder flows out without allowing projection.

This shell can either be the entirety of the inside of the Take in the sleeve with the release of gas vents, or only part of it.

The accompanying drawings show non-limiting exemplary embodiments of the invention, which are described below will.

On the drawing show:

Fig. 1 is a longitudinal section through an exercise cartridge with a., ..., Cover made of synthetic material. ,

Fg. 2 in different scales a cartridge that comes with a inner shell is provided, which is extended to the bottom of the case. 90 98 1 8/0016

Fig. 3 shows a modified embodiment for a cartridge of a pistol or the like.

The cartridge consists of a metallic sleeve 1 with a shoulder 2 and a neck 3. Inside it has an insert 4 made of plastic material with a cylindrical lower part, which adapts to the circumference of the sleeve, while it does not cover the bottom, but at a height 5 of the body of the powder chamber cuts off.

The insert 4 is provided on its upper part with a shoulder 6 which rests against the socket 2 and which merges into a neck 7, the end of which forms a hollow pointed arch 8. The inner and outer η parts of the shell consist of a preferably meltable synthetic material and have completely the same thickness.

The inner sleeve 9 according to FIG. 2 is of the same type and extends inside the metallic sleeve Io as far as the sleeve base 11. The end 12 ¹ 1H ^t exposes the sleeve base 14 and the holes 13.

The transition 15, which forms the outer part of the sleeve, has the same thickness as the inner body 9.

Revolver cartridges according to FIG. 3 also have an outer sleeve 16 made of metal, with an inner casing 17 made of synthetic material, the lower part of which leaves the holes 18 free and the upper part 19 of which forms the ball.

The training according to the invention has multiple advantages.

The shell ⁿ according to FIGS. 1, 2 and 3 have essentially the same properties with regard to the combination of the metallic sleeves with inner sleeves of synthetic material which form the sphere and they are elongated into a body or extend to the bottom of the Sleeve.

The sheath 4 offers economy of the material and the advantage that after the shot has been fired, the casing 4 and the point 8 fall to the bottom of the case in position 4 '. This facilitates the ejection of automatic weapons. The counter pressure resulting from the pressure reduction is used for this purpose.

In contrast to this, after the end of the cartridges according to FIGS. 2 and 3, the tips 15, 19 remain protruding.

The usefulness of this device arises from the combinations of advantages that are obtained, namely part of the Kaliberdruc kes not encountered in the whole elastic cartridges and the stiffness and thermal resistance, which fix all the Na chteile that come with shots automatic or automatic weapons exist, the ease of insertion that is in a "i band or a charger, the regularity of the caliber of the gun chambers v« «u ^r p *" ^r and the ease of extracting CHT by sliding!. · -; ·· ■ -! -.

On the other hand, the tip made of synthetic material calls the same strength as the inner sheath body 4, 9 or 17 No parts protruding when fired, because the flame or that triggered by the fire being released from the powder Heating is used to create a melting or burning with an instant charring in a zone 2o or 21 is used at the top of the tip. In the worst case, the protrusions of the lowest parts of the shot avoid who have no indolence, any risk of accidents.

The gases escape through these openings without interruption. In this way, the traces of the shot are avoided, the Create cracks, or locate the splinters, which always cause the ejection of small pieces. The easy one Resistance, which precedes the escape of the gas, gives the cartridge sufficient return to the automatic To ensure emissions.

Furthermore, the strength of the metal and the synthetic Materials are reduced, resulting in a significant economy for the first material.

The shapes, dimensions, arrangements of the various parts can be changed within the framework of YQn equivalents, as can the materials used for production without going beyond the scope of the inventive concept.
