PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Athmungsvorrichtung, welche ein Eindringen in mit Rauch oder schädlichen Gasen gefüllte Räume ermöglichen soll, und bezweckt insbesondere, auf einfache Weise die Möglichkeit zum Hören und Geben von Signalen zu gewähren.The invention relates to a breathing device which allows smoke to penetrate or harmful gases is intended to enable spaces filled with, and in particular aims to easy way to give the opportunity to hear and give signals.
. In beiliegender Zeichnung zeigt: Fig. 1 den Helm der Athmungsvorrichtung im Schnitt, von der Seite gesehen, Fig. 2 denselben von vorn, gesehen, halb im Schnitt.. In the accompanying drawing: Fig. 1 shows the helmet of the breathing device in section, seen from the side, Fig. 2 the same from the front, seen, half in section.
Ein Metallhelm 1 besitzt unten eine festschnürbare Lederverlä'ngerung 2, über welcher die Uniform oder der Rock zugeknöpft wird. Ein Kopfpolster 3 ist federnd an dem Helme 1 befestigt, um den Druck desselben auf den Kopf zu mildern. Federnde Rohre 4, auf der Innenseite mit Polsterung 5 versehen, führen beiderseits durch Ansätze 6, die vermittelst Klappe 7 verschliefsbar sind, nach aufsen, wodurch erzielt wird, dafs derjenige, welcher den Helm benutzt, um ihn stattfindende Geräusche und etwaige Signale zur persönlichen Rettung vernehmen kann, ohne dafs der im Helm befindliche Sauerstoff verloren geht. An der Vorderseite des Helmes ist ein Fenster 8 aus Marienglas angeordnet. Da dasselbe in der ersten Zeit nach dem Aufsetzen beschlägt, mufs es geputzt werden, was durch eine geeignete Putzvorrichtung geschehen kann.A metal helmet 1 has a leather extension 2, which can be tied down, over which the uniform or skirt is buttoned. A head pad 3 is resilient on the helmet 1 attached to relieve its pressure on the head. Resilient tubes 4 on which Inside provided with padding 5, lead on both sides through lugs 6, which mediate Flap 7 are closable to the outside, whereby it is achieved that the one who the Helmet used to hear any noises taking place and any signals for personal rescue can hear without losing the oxygen in the helmet. At the A window 8 made of Marienglas is arranged on the front of the helmet. Since the same in the If it starts to fog up after putting it on, it must be cleaned, which is done by a suitable one Cleaning device can be done.
Der Sauerstoff wird durch die Rohrleitung 20 in den Helm, die verbrauchte Luft durch die Rohrleitung 28 aus demselben herausgeführt. Das Mundstück 23 ist durch eine Klappe 26 von aufsen verschliefsbar. Der vordere Theil desselben ist derart ausgebildet, dafs eine zweckentsprechend geformte Signalpfeife oder Huppe 27 von aufsen eingesteckt werden kann, ohne dafs Sauerstoff verloren geht oder Aufsenluft eindringt.The oxygen is through the pipe 20 in the helmet, the stale air through the Pipeline 28 led out of the same. The mouthpiece 23 is closed by a flap 26 lockable from the outside. The front part of the same is formed in such a way that a appropriately shaped signal whistle or horn 27 can be inserted from the outside, without oxygen being lost or outside air entering.
