Die Zündhütchen der Patronen für das Militä'rgewehr werden in die cylindrische Vertiefung am hinteren Ende, der Hülse mit so grofser Gewalt eingeprefst, dafs einerseits ein wasserdichter Verschlufs entsteht und andererseits verhindert wird, dafs die Zündhütchen unter dem Druck der Pulvergase zwischen Lauf und Verschlufskopf herausgeschlagen werden, dafs also das Gewehr nicht spritzt. ,The primers of the cartridges for the military rifle are in the cylindrical recess at the rear end, pressed into the case with so great force that on the one hand a A watertight seal is created and, on the other hand, it is prevented that the primer caps are knocked out under the pressure of the powder gases between the barrel and the sealing head, so that the rifle does not squirt. ,
Dieser letztere Uebelstand tritt ein, sobald der Gasdruck diejenige Grenze überschreitet, welche bei dem Gewehr Modell 88 eingehalten ist;This latter situation occurs as soon as the gas pressure exceeds the limit which is complied with for the Model 88 rifle;
Um nun höhere Gasdrücke und damit höhere ballistische Leistungen zu ermöglichen, wird zwar das Hütchen cylindrisch belassen mit Rücksicht darauf, dafs es in eine Oeffhung eingeprefst werden mufs, welche auf einer Seite geschlossen ist; es wird aber die Kammer für das Hütchen nach vorn erweitert.In order to enable higher gas pressures and thus higher ballistic performance, it is true that the cap is left cylindrical, taking into account that it is in an opening must be pressed in, which is closed on one side; but it becomes the chamber for the cone extended to the front.
Unter dem Druck der Pulvergase wird nun das letztere. sowohl nach hinten gedrängt als auch ausgeweitet, so dafs es sich an die Kammerwände anpreist und deren Form annimmt. The latter is now under the pressure of the powder gases. both pushed backwards as also widened, so that it embraces the chamber walls and assumes their shape.
In Fig. ι ist die Patrone mit dem Zündhütchen α vor dem Schufs und in Fig. 2 nach dem Schufs gezeichnet.In Fig. Ι the cartridge with the primer α is drawn before the Schufs and in Fig. 2 after the Schufs.
Das ausgeweitete Hütchen kann nicht mehr herausgeschleudert werden, da der dickere Theil durch die engere Mündung austreten müfste. Der gasdichte Abschlufs wird durch das Einpressen des Hütchens in die enge Mündung mit wachsendem Druck gebessert.The widened cap can no longer be thrown out because the thicker one Part of it would have to emerge through the narrower mouth. The gastight conclusion is through the pressing of the cap into the narrow mouth improved with increasing pressure.
Unter der Voraussetzung ausreichender Wandstärken können die jetzigen Gasdrücke vervielfacht werden. Dabei kann die Form der Erweiterung der Kammer eckig, konisch oder rund sein.Provided that the wall thickness is sufficient, the current gas pressures can be multiplied. The form of the extension the chamber be square, conical or round.
