PATENTAMT.PATENT OFFICE.

Wird der Verschluß, namentlich größerer Geschütze, nach dem Schuß geöffnet, so tritt eine Belästigung der Bedienungsmannschaften durch die austretenden Pulvergase mehr oder weniger immer ein. Besonders stark wird die Belästigung aber dann, wenn die Gase nicht unmittelbar ins Freie, sondern zunächst in fest abgeschlossene Räume übertreten, wie dies bei Panzertürmen der Fall ist, inIf the breech block, especially of larger artillery, is opened after the shot, it will kick a nuisance of the operating crews by the escaping powder gases or more less always one. The annoyance is particularly strong when the gases do not step directly into the open, but first step into tightly closed rooms, like this is the case with armored turrets, in

ίο denen meistens auch mehrere Geschütze aufgestellt sind.ίο which usually set up several guns are.

Zur Beseitigung dieser Übelstände sind bereits verschiedene Vorschläge gemacht worden. Man hat besonders durch einen ständig wirkenden Preßluftstrom vor der Mündung des Geschützes eine indirekte Saugwirkung zu erzielen versucht, indem man an der Mündung in Richtung des Rohres gepreßte Luft 'ausströmen ließ. Diese indirekte Saugwirkung ist aber naturgemäß eine sehr schwache und wird schon durch gegen die Geschützmündung gerichtete schwache Winde gänzlich aufgehoben. Ferner können hierbei die Pulvergase selbst ihren Weg nur durch die Geschützmündung nach außen finden, und zwar auch nur dann, wenn der Verschluß des Rohres geöffnet ist. Sobald dieser aber geöffnet wird, dringt stets sofort so viel Rauchgas in den Turm, daß die beabsichtigte Wirkung illusorisch wird. Selbst wenn man mit dieser Vorrichtung an der Mündung des Rohres etwas Rauch absaugt, wird dieser zum großen Teil durch die Schießscharten schon bei schwachem Winde wieder in den Turm getrieben. Various proposals have already been made for eliminating these deficiencies been. There is an indirect suction effect, especially through a constant stream of compressed air in front of the muzzle of the gun tries to achieve by allowing compressed air to flow out at the mouth in the direction of the pipe. This indirect Naturally, suction is very weak and is already through Weak winds directed against the gun muzzle completely abolished. Furthermore, the powder gases themselves can be their own Only find a way out through the muzzle of the gun, and only if the breechblock of the barrel is open. As soon as this is opened, however, so much smoke gas immediately penetrates the tower, that the intended effect becomes illusory. Even if you are using this device If some smoke is sucked off at the mouth of the pipe, this is largely already through the loopholes driven back into the tower in a weak wind.

Man hat ferner versucht, in das Bodenstück des Rohres Preßluft einzuführen und vermittels dieses Gebläses die Rauchgase durch das Rohr selbst nach außen herauszublasen. Dies kann aber erst stattfinden, wenn nach dem öffnen des Verschlusses die Kartuschhülse hinten herausgezogen ist. Hierbei tritt aber jedesmal sowohl durch das offene Keilloch als auch aus der Kartuschhülse ein so erheblicher Teil der Rauchgase in den Turm, daß auch diese Einrichtung den beabsichtigten Zweck ganz und gar nicht erfüllt.Attempts have also been made to introduce compressed air into the base of the tube and by means of this fan to blow the smoke gases out through the pipe itself to the outside. However, this can only take place after the closure has been opened the cartridge sleeve is pulled out at the rear. Here, however, both occur each time the open wedge hole as well as from the cartridge casing such a significant part of the smoke gases into the tower, so that even this facility does not at all serve the intended purpose.

Im Gegensatz zu der bisher bekannt gewordenen Anwendung von Preßluft wird bei der vorliegenden Einrichtung Saugluft angewendet, und zwar in erster Linie bei Geschützen mit Keilverschlüssen. Zu diesem Zweck wird über diejenige Öffnung des Keilloches, welche beim Herausziehen des Keils frei wird, eine Kappe angebracht, an welche eine Saugleitung angeschlossen ist. Durch die Kappe werden vermittels der Saugleitung die Rauchgase durch einen Exhaustor oder eine andere Saugwirkung erzeugende Vorrichtung abgesaugt und im weiteren Verlauf durch eine an den Exhaustor sich anschließende Druckleitung an beliebig zu wählender Stelle ins Freie, wo sie nicht mehr lästig wirken, gebracht.In contrast to the previously known use of compressed air, with The present device used suction air, primarily for guns with wedge locks. For this purpose, the opening of the wedge hole, which when pulling out the Wedge is free, a cap is attached to which a suction line is connected. The flue gases are passed through an exhaustor through the cap by means of the suction line or another suction generating device and then through one to the exhaustor subsequent pressure line at any point to be selected into the open, where they no longer act annoying, brought.

Claims

Even while the cartridge sleeve is sliding out to the rear, the smoke gases are sucked out of the pipe so that they cannot penetrate the tower. Furthermore, with this device you are pretty much independent of the wind, which under certain circumstances can only increase the suction effect. ίο The device shown for example in the drawing shows in Fig. ι the locking piece of a gun barrel with a round wedge inserted therein; Figure 2 is an end view. Above the closure opening of the pipe a, from which one end of the closure wedge b protrudes laterally after loading has taken place, a closure cap c is held on the pipe by means of clamps d. λ'Όη of the cap c lead one or more hoses / or articulated pipes to an exhaustor, not shown, which can be set up at any point and operated electrically. The hoses or articulated tubes must be of sufficient length to be able to adapt to the movements of the gun barrel in any direction. The exhaustor is constantly in operation for the duration of the shooting. The power of the same is dimensioned in such a way that it continuously generates a powerful air flow with a suction effect that promotes about 2 cbm of air per second. If, after the shot has been fired, the breechblock is opened and at the same time the bullet casing is pulled out of its bearing, this first closes the breech block to the rear for a moment. During this process, all the powder gases present in the gun barrel and also the powder gases in the cartridge case are sucked off by the constant powerful action of the exhaustor, and are completely removed by the exhaustor, for which a few seconds are sufficient. The device described is mainly applicable to all types of wedge locks. As determined by tests, the above-described device, in contrast to the previously known devices, allows the smoke to be carried out of the tower into the open at any point independently of the gun, where it can no longer be a nuisance. Godfather ν ϊ-Αν Proverbs:

1. Device for removing powder gases from gun barrels, thereby characterized in that a suction line consisting of one or more suction pipes is attached to the closure opening on the closure piece respectively Hoses connected.

2. Apparatus according to claim 1, characterized in that a cap (c) for the connection of the suction line is held over the closure opening of the gun and the latter is connected to an exhaustor.
