KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Da beim Abfeuern eines Geschützes eine grofse Wärmeentwickelung stattfindet, welche die inneren Metallschichten plötzlich stark erhitzt und ausdehnt, während die äufseren durch die Luft, besonders bei Frostwetter, gekühlt werden, so entstehen in dem Material des Geschützrohres Spannungen, welche auf dasselbe einen nachtheiligen Einflufs ausüben.Since when a gun is fired there is a great development of heat, which the inner metal layers suddenly heats up and expands, while the outer layers through the air, especially in frosty weather, are cooled, so arise in the material of the Tensions in the gun barrel which exert a detrimental influence on it.
Dieser nachtheilige Einflufs giebt sich zu erkennen durch Risse im Geschützrohr, Unbrauchbarwerden oder gar Bersten desselben bezw. durch die . kurze Lebensdauer des Geschützes. This detrimental influence can be recognized by cracks in the gun barrel, rendering it unusable or even bursting of the same respectively. through the. short life of the gun.
Den schädlichen Einflufs thunlicht zu vermeiden und dadurch das Geschütz möglichst lange Zeit brauchbar zu erhalten, ist der Zweck der vorliegenden Erfindung.To avoid the damaging influence, and thereby the gun as much as possible To keep usable for a long time is the purpose of the present invention.
Um diesen Zweck zu erreichen, mufs die "innere Wandung des Rohres gekühlt bezw. die Wärmeentwickelung verringert werden, welches auf folgende Weise geschieht:To achieve this purpose, the "inner wall of the pipe must be cooled or. the heat generation can be reduced, which happens in the following way:
Nach dem Einbringen des Geschosses werden, wie die beiliegende Zeichnung veranschaulicht, entweder mit der Kartusche C verbundene Hülsen a oder hinter derselben besondere Hülsen α eingeführt, welche mit flüssiger oder stark verdichteter Kohlensäure geladen sind. Diese Hülsen werden beim Abfeuern durch die rückwirkende Kraft der Pulvergase gesprengt und die Kohlensäure wird durch den entstehenden hohen Druck noch mehr verdichtet. "Sobald aber das Geschofs den Lauf verlassen und somit auch der Druck aufgehört hat, dehnt sich die Kohlensäure aus und verflüchtigt sich zu Gas, wobei der erwärmte Lauf wieder abkühlt, ehe die Wärme das Material desselben zu durchdringen vermag.After the introduction of the projectile, as the accompanying drawings illustrates, either associated with the cartridge C sleeves a or α introduced behind the same special sleeves which are loaded with liquid or highly compressed carbon dioxide. When fired, these shells are burst by the retroactive force of the powder gases and the carbon dioxide is compressed even more by the resulting high pressure. "But as soon as the bullet has left the barrel and thus the pressure has ceased, the carbonic acid expands and evaporates into gas, whereby the heated barrel cools down again before the heat can penetrate the material of the same.
Die Kohlensäure erleidet, wie durch zahllose praktische Versuche erwiesen ist, bei diesem Vorgange keinerlei chemische Veränderung und erfüllt daher ihre Bestimmung in vollkommener Weise.The carbonic acid suffers, as has been shown by innumerable practical experiments, in this Processes do not have any chemical changes and therefore fulfills their purpose perfectly Way.
Mit Hülfe dieses Verfahrens können die Geschütze schneller nach einander abgefeuert werden und erhalten eine bedeutend verlängerte Dauer.With the help of this procedure, the guns can be fired more quickly one after the other and have a significantly longer duration.
