Description

Paten τ-An Spruch:Godfather τ-An saying:

■ Elektrische Beleuchtungsanlage für Bergwerke, dadurch gekennzeichnet, daß das Innere der mit luftdicht abschließenden Glasglocken versehenen Beleuchtungskörper, gegebenenfalls mit Einschluß des Zuleitungskabeis, an eine Leitung angeschlossen ist, welche mit Druckluft gespeist wird, so daß beim Zerstören und Freilegen eines Beleuchtungskörpers durch die herausblasende Luft sofort etwaige explosive Gase beseitigt und Explosionen verhindert werden.■ Electrical lighting system for mines, characterized in that the Interior of the lighting fixtures provided with airtight glass bells, if necessary including the supply cable, is connected to a line, which is fed with compressed air, so that when a lighting fixture is destroyed and exposed the air blown out immediately removes any explosive gases and prevents explosions.

KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Gegenstand der Erfindung ist eine Einrichtung, durch welche eine explosionssichere Beleuchtung der jeweiligen Arbeitsstelle in Bergwerken ermöglicht wird. Dieselbe kennzeich- net sich dadurch, daß elektrische Beleuchtungskörper in der Weise angebracht sind, daß beim Zerbrechen derselben durch Auffallen von Gebirgsteilen das etwa vorhandene explosive Gas aus der Lampennähe entferntThe invention relates to a device by means of which explosion-proof lighting the respective job in mines is made possible. Same mark- net is that electric lighting fixtures are attached in such a way, that when it breaks through the falling of parts of the mountains, whatever is present explosive gas removed from the vicinity of the lamp ίο wird.ίο will. Der Erfindungsgegenstand ist in der Zeichnung in einer beispielsweisen Ausführungsform dargestellt.The subject of the invention is shown in the drawing in an exemplary embodiment shown. Das elektrische Kabel α ist in eine Rohrleitung b eingeschlossen, welche mit Druckluft gespeist wird. An dem Rohr oder an mit diesem verbundenen Zweigen c bzw. Schläuchen sitzen die an das Kabel angeschlossenen Lampen d, welche mit einer geeigneten Glocke e umgeben sind, die luftdicht abgeschlossen ist. Diese Einrichtung bietet den Vorteil, daß beim Zerbrechen der Glocke und der Birne durch herabfallendes Gestein o. dgl. etwa vorhandene explosive Gase nicht entzündet werden können, weil die Glocke mit Druckluft gefüllt ist und weil die Gase durch die sofort beim Zerbrechen der Lampe kräftig ausströmende, die Birne allseitig umgebende Luft entfernt werden, so daß sie an die durch die Wirkung des elektrischen Stromes glühenden Teile bzw. entstehenden Funken nicht herantreten können.The electrical cable α is enclosed in a pipe b which is fed with compressed air. The lamps d connected to the cable, which are surrounded by a suitable bell e , which is hermetically sealed, sit on the pipe or on branches c or hoses connected to it. This device has the advantage that if the bell and the bulb break due to falling rock or the like, any explosive gases present cannot be ignited because the bell is filled with compressed air and because the gases emit vigorously when the lamp breaks , the air surrounding the bulb on all sides must be removed so that they cannot touch the glowing parts or sparks produced by the effect of the electric current. Es tritt dann überdies die in die Leitung gewöhnlich eingeschaltete, durch den nachlassenden Strom beeinflußte Sicherheitsvorrichtung in Tätigkeit, welche den Stromkreis unterbricht, so daß auch dann, wenn der Luftstrom etwa erschöpft würde, keine Explosion mehr eintreten kann. Da das elektrische Kabel gleichzeitig in das Luftleitungsrohr eingelegt werden soll, was aber nicht unbedingt erforderlich ist, so ist dasselbe gegen Beschädigungen möglichst geschützt, und es wird auch dann die Gefahr der Explosion möglichst beseitigt, wenn durch einen Bruch des Kabels Kurzschluß entstehen sollte, weil auch dann die Druckluft das Gas nicht zu der betreffenden Stelle treten läßt. Es könnte auch die Einrichtung getroffen werden, daß an den Beleuchtungskörpern fortwährend eine geringere Menge Luft austritt, welche die Gase zurückhält.In addition, the one usually switched on in the line occurs through the declining one Current affected safety device in action, which interrupts the circuit, so that even if the Air flow would be exhausted, no more explosion can occur. Since the electric Cable is to be inserted into the air duct at the same time, but this is not necessarily the case is required, it is protected against damage as much as possible, and it the risk of explosion is eliminated as far as possible even if by a rupture the cable should short-circuit, because even then the compressed air does not supply the gas the place concerned. It could also be set up that A smaller amount of air is constantly escaping from the lighting fixtures, which is the gas holding back.
