Cartridge case

Priority: France, from April 11, 1963

The subject of the! Increase in prices is a cartridge case, which ζ · Βν for shooting ranges or for! Local throwing of Objects such as grenades, dowels, etc., is intended.

The sleeve according to the innovation is in particular

remarkable in that it has an outer jacket made of a resistant material, in the bottom of which there are the usual primer is located, with a closed jacket made of a less rigid material inside = this jacket, e.g. made of plastic, which is attached to his The front end is closed and practically completely covered with powder or another substance forming the propellant charge is filled.

© emass another characteristic of the furnace stand the side walls of the inner jacket with the side walls the outer jacket in contact so that the inner ^ the jacket practically adapts to the lOrm of the outer jacket.

According to another characteristic of hiring is the front closed section of the inner jacket slightly behind the front end of the outer jacket »

According to another characteristic of inflation with a given outer jacket, the thief depends Mt sidewalls of the inner jacket of the tolumen that of this load to be picked up.

The above training offers the following gate parts:

First is the one containing the powder charge

, Inner jacket completely tight, so that the charge against moisture is protected. There is therefore no longer any need for any special precautionary measures for the storage of the finished cartridges to be hit.

The second part of the goal is that the The inner volume of the jacket to accommodate the powder charge can be precisely matched to the tolumen of this charge. As is well known is an essential factor in the manufacture of cartridges the charge density, i.e. the ratio between the inside the available tolumen of the cartridge and the tolumen of the powder. To create optimal conditions, this ratio must generally between about 0.80 and 1 »but Hun can the tolumen available in the inner jacket can be conveniently adapted to the powder volume to be absorbed, e.g. by appropriate Choice of the thickness of its side walls *

Learner must be known to ensure a complete ignition of the charge of the deflagration.

λ white resistance are opposed * This is generally generated by a ball crimped into the sleeve * where the force required to tear them out is just

>. creates this resistance *

"If it looks like a ball ζ .B * for

Shooting at shooting ranges or around a cartridge for targeting is about objects, e.g. grenades etc., this resistance is no longer present or at least completely insufficient. In the case of the sleeve according to the innovation, however, this is the case Resistance due to the complete closure of the inner jacket always present for any object to be sealed off. From this it follows that even a ball consists of Plastic, i.e. * lightweight, which is attached to the neck of the sleeve by means of a very short cylindrical guide can be shot under excellent conditions, since the thin front wall of the inner jacket creates a a good increase in powder pressure and thus a uniformity of the thrust is guaranteed.

Another "advantage is that the sleeve has a low weight and a very low weight Has cost price.

The novelty is below by reference explained on the drawing by way of example.

Fig. 1 is a longitudinal section of an embodiment of a sleeve according to the innovation *

]? ig * 2 shows a in the same representation

Design modification.

In the embodiment of the I ¹ Ig. 1 has the

Sleeve on an outer jacket 1, which e.g. * made of light metal consists, e.g. aluminum ο «the like .. * This jacket" has in his

Bottom a point 2 for receiving the primer while he front has a shoulder 3 on which a cylindrical * "section 4 follows, which forms the neck and is intended, for example, to accommodate a projectile 5 according to the on July 31, 1953 with the vain "bullet" under the Kummer G 38.368 Ic / 72d filed German patent application be trained.

Inside the shell 1 is a

further jacket 6, which is made of plastic, for example. This is open at the back at 7, where. .that closely adjoins the inner walls of the jacket 1 * At the front this jacket 6 is blind at 8 * * sen, e.g. * through a wall section, which can either be attached (by gluing, stapling, welding, etc.) or with the Coat can form one piece. This find section can e.g. be arranged approximately perpendicular to the longitudinal axis of the sleeve.

The thickness of the wall section 8 is proportionate small to make it easier to tear when fired. The thickness of the side walls of the shell β, however, is considerable greater. It should be noted that this applies to the individual cartridges can be different. The powder charge which the cartridge is supposed to contain, and which, as stated above, make them practical must fill out completely, can be changeable *

The free one available inside the 6 jacket

The volume must therefore adapt to the tolumen of the powder charge can. This adjustment can be done very conveniently in that given the side walls of the shell 6 a corresponding thickness will.

When fired, the primer ignites the powder charge contained in the jacket 6, and the thrust of the ^! Gases bursts the wall section 8 and drives the G'esehoss | k forward · · ■■■ "-.

The sleeves shown in Figure 1 are

especially suitable for shooting on the shooting range «Es balls of the type shown at 5 are then used, which practically sit with the bottom on the wall 8 *

It turns out that the thrust of the gas is determined solely by the presence of the wall 8, and that it is by no means necessary, a particularly serious one Attachment or bordering of the projectile in the section of the outer jacket to create a resistance,

ir. '

^c as is the case with the known cartridges, to enable unclean, even firing of the projectile

In Fig. 2 a cartridge is shown which can be used for firing grenades, evils, etc. The sleeve according to the innovation shown in this figure is essentially designed like that of FIG. 1, with the exception of the end of its front part. Section 4 needs no longer to be cylindrical, as in Fig. 1> The ribbons are simply folded as shown at 9. When fired, the thrust of the charge pierces or breaks the wall section 8 and opens the fold 9
