Description

Elektrische Grubenlampe mit Schutzglocke Es sind bereits verschiedene Sicherheitsvorrichtungen zur Verhinderung der Entzündung von Schlagwettern durch elektrische Glühlampen vorgeschlagen worden, welche auf mechanischem Wege die Stromzuführung abschalten. Bei den bekannten Anordnungen wird dabei aber völlige Schlagwettersicherheit nicht erzielt, da schon das Nachglühen der Lampe oder der Unterbrechungsfunke beim Abreißen der Glühfäden genügt, um Explosionen in Schlagwetterbetrieben zu verursachen. Aufgabe der Erfindung ist es, das Entstehen von Explosionen zu verhindern.Electric miner's lamp with protective bell There are already different ones Safety devices to prevent the ignition of firedamp through electric incandescent lamps have been proposed, which mechanically supply the power switch off. In the case of the known arrangements, however, there is complete protection against firedamp not achieved because the afterglow of the lamp or the interruption spark in the Tearing off the filaments is enough to cause explosions in firedamp operations. The object of the invention is to prevent explosions from occurring.

Erfindungsgemäß enthält die die Lampe umgebende Schutzglocke oder die Lampenglocke selbst Gesteinsstaub, der bei der Zertrümmerung der Gläser aufgewirbelt und gegen die nachglühenden Metallfäden geschleudert wird. Zweckmäßig ist es, den Gesteinsstaub in einen besonderen Behälter einzubringen, der bei Zertrümmerung der Glasteile der Lampe mittels mechanischer Verbindungsglieder zwangsläufig geöffnet wird, so daß der Gesteinsstaub austreten und das Leuchtsystem umgeben kann.According to the invention contains the protective bell surrounding the lamp or the lamp bell itself is rock dust, which is whirled up when the glasses are smashed and is thrown against the afterglowing metal threads. It is useful to use the Bring rock dust into a special container, which should be removed from the Glass parts of the lamp inevitably opened by means of mechanical connecting links so that the rock dust can escape and surround the lighting system.

Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt. In Fig. i ist die Lampe mit a bezeichnet. Sie ist von einer Schutzglocke b umgeben, die wiederum durch eine Glocke c aus Drahtgeflecht geschützt ist. Der Raum d zwischen der Lampe a und der Schutzglocke b und die Lampe a selbst enthält Gesteinsstaub e. Dieser kann auf dem Grund der beiden Glasglocken a, b gegenüber dem Glühfaden vorgesehen sein oder auch in einem besonderen Raum f. Bei Zertrümmerung der Gläser a, b wird der Gesteinsstaub aufgewirbelt und gegen die nachglühenden Fäden geschleudert, so daß diese völlig eingehüllt sind und gegen die eine Zündung explosibler Gase unmöglich gemacht ist. Gemäß Fig. a ist der Gesteinsstaub ein einem besonderen Behälter g enthalten, der oberhalb der Lampenfäden angebracht ist. Das Gehäuse g, an dem die Fassung der Lampe a sitzt, ist an mehreren Stellen mit schrägen Ausläufen h, i versehen, deren Öffnungen durch dünne Glasplättchen k abgeschlossen sind. In dem Raum d ist ein Ring mit Stoßdornen L vorgesehen, die bei Zertrümmerung der Gläser die Glasplättchen k durchstoßen und den Austritt für den Gesteinsstaub freigeben, der infolge der schrägen Lage des Gehäuses gegen das Leuchtsystem geführt wird.Two embodiments of the invention are shown in the drawing. In Fig. I the lamp is denoted by a. It is surrounded by a protective bell b, which in turn is protected by a bell c made of wire mesh. The space d between the lamp a and the protective bell b and the lamp a itself contains rock dust e. This can be provided on the bottom of the two glass bells a, b opposite the filament or in a special room f. When the glasses a, b are broken, the rock dust is whirled up and thrown against the glowing threads so that they are completely enveloped and against ignition of explosive gases is made impossible. According to FIG. A, the rock dust is contained in a special container g which is attached above the lamp filaments. The housing g, on which the socket of the lamp a sits, is provided at several points with inclined outlets h, i , the openings of which are closed by thin glass plates k. In the space d a ring with push pins L is provided, which pierce the glass plate k when the glasses are shattered and release the exit for the rock dust, which is guided against the lighting system due to the inclined position of the housing.
