Description

Cartridge loading This calls for more and more long pipes, long, heavy ones Bullets and high initial speeds. The latter are only strong by virtue of their strength To achieve charges. The explosiveness of these charges can only be determined by matching them Moderate charge build-up.

For this purpose, one should first switch from the bottom ignition to the front ignition skillful in order to ensure that the charge remains calm on the ground after the ignition has taken place the cartridge remains. Then you put the load together from different parts; the front ones were supposed to burn from slowx, the rear ones from ever faster Powders exist. These parts were then made from solid pieces, those from special pieces Covers. quite slowly combustible material were surrounded in order to reproduce to secure the inflammation from piece to piece.

Neither of these procedures fully achieved the purpose; the first - the resulting ignition flame passes through or envelops the surfaces of the whole load and its parts at the same time, burns through the hulls and brings it to the fact that the rear, higher nitrided pieces of the charge the front, lower nitrated in front of you h.ea-: shoot.

The advance should be to prevent the ignition flame and propellants can somehow beat backwards. This is achieved by wrapping the individual parts of the load with a jacket-like, @elastic-, through. Admixture mitigating substances to the slowest combustion capable nitro compound with which they firmly pressed together into the cartridge sleeve piece by piece and one below the other and cemented together with the cartridge sleeve and ignition tube. When firing should also the pressure of the resulting propellant lane holds the cargo firmly against the floor and wall of the Keep the cartridge cases wedged so that the glowing gases are not even the slightest Can find gaps, even if the sleeve is resilient based on the pipe wall gives way. The inner wall of the K, artus sleeve and outer surface of the cargo must therefore be weak Get a conical shape, as is customary in the manufacture of sleeves. Of the Elastic nitro lacquer then creates a complete seal. The ignition tube must also be like this be rigid so that it can withstand the pressure of the propellant gases and, through the same, weak The conical shape of the load ensures the same, firm support.

The parts of the load could be level with each other delimit. It is more advantageous; them; to give spherical interfaces, their common Center coincides with the point of inflammation; then each: part is complete burned out before the inflammation over the burning layer of paint to the next propagates. In the case of a flat boundary, parts of a rear section would already be. Be burned when parts of your own front are still burning, bumps instead of calm pressure tolerance would be inevitable.

With a smaller caliber, the strong, rigid tube would become undesirable Lead the extension of the cartridge, the lighter bullets also tolerate faster burnable charges; here can be the rigid, metal Ignition tube be replaced by a cardboard tube. To nevertheless charges from lower and higher To be able to use nitrided pieces, one leads the ignition tube almost through the whole Charge up to the foremost, thick part of a slightly nitrided, pointed hollow cone-shaped Powder body. The inflammation propagates along the yielding ignition tube, but only ever finds powder of low nitration; : only this can it apply to the reproduce higher nitrated bodies of counter cone shape. Also for this charge arrangement the cartridge sleeve, pieces of powder and ignition tubes must burn slowly among themselves Nitro lacquer be glued.

The construction of the load from individual pieces also enables one cheaper form of additional loading of salt cartridges.

The muzzle flame does not simply consist of hot propellant gases. These rather, if they contain an excess of carbon oxide, they only flame before the mouth when they take in oxygen from the open air.

Salt cartridges that have hitherto been included; the gases should have the necessary Provide oxygen in the pipe. You could. so far only used as a summons. In future, they should be layered between the cargo items so that they can get through the resulting propellant can be atomized immediately while still inside the cartridge and can better supply their oxygen to the carbon dioxide. Must be in their form they must be adapted to the shape of the cargo body, together with them and the nitro lacquer, who has to encase them into: the cartridge sleeve and are sieve-like be perforated to prevent the combustion from spreading from cargo to cargo to enable.

The execution is shown in the drawings.

The cartridge sleeve h (Dept. i and 2) takes from the front to the back outside and inside conical in thickness, the metal ignition tube z (section i) likewise. In the disc diameter of the individual items of cargo increases in reverse proportion t (section i) conically from. The strong lines show the putty of each. Charges with each other and with I # .'- artush sleeve and ignition tube through the nitro lacquer (Dept. i and 2). The mutual boundary surfaces of the individual items of cargo among each other have the point of inflammation am as their common center of curvature front end of the ignition tube e (section z) are spherical surfaces. With smaller I <-% uber the cardboard ignition tube z (Fig. 2) extends very deep into the thick part of the, lower nitrided charge bodies of pointed hollow cone foran, the inflammation happens at the ignition point e (Fig. 2) and runs quickly on the yielding ignition tube along without finding higher nitrated powder; it only occurs on the higher nitrated one: Charging body / z of an opposing cone shape when body t is completely burned out.

The salt cartridge disks s (Fig. I and 2) lie in the shape of a bowl like a sieve perforated, covered by nitro lacquer, between the cargo bodies.

Claims (5)

PATENT CLAIMS: i. Cartridge load, made of nitro powder with after increasing burning speed at the rear with the interposition of slower combustible layers built up around an ignition tube, characterized in that that the layers separating the individual rags are made of an elastic nitro lacquer exist, which is applied in such a way that it also includes any gaps between the ignition tube and cartridge wall fills. 2. Cartridge load according to claim i, characterized in that that the ignition tube is so rigid that it can withstand the pressure of the powder gases and, growing backwards slightly conical in strength, as well as conical in thickness increasing cartridge case of the charge when firing grants firm support. 3. Cartridge loading according to claim i and 2, characterized in that the powder body exactly into the Kaxtush sleeve and around, the rigid ignition tube fit, but under each other with spherical necks Areas are limited, their common center of curvature at the point of inflammation is at the front end of the ignition tube. q .. Cartridge load according to claim i for smaller ones Caliber, characterized in that using a gas pressure not withstanding Ignition tube the nitro powder layers separated by nitro lacquer have the shape of a pointed, interlocked # ter have hollow cone. 5. cartridge charge according to claim i to q. with the addition of Salt layers, characterized in that the salt layers are sieve-like in shape perforated discs between: the nitro powder layers pressed in and from the nitro lacquer be enveloped.
