Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei den Versuchen auf der berggewerkschaftlichen Schlagwetterversuchsstrecke in Gelsenkirchen hat sich herausgestellt, daß eine Entzündung schlagender Wetter durch elektrische Glühlampen nur dann eintreten kann, falls durch irgendeinen Umstand die Glühbirne zerbricht, wobei der Faden erhalten bleibt. Diese Möglichkeit ist um so größer, falls niedervoltige Glühlampen, welche verhältnismäßig kurze und dicke Glühfäden besitzen, verwandt werden, wie z. B. bei elektrischen Grubensicherheitsl ampen.During the tests on the mountain union fire-weather test track in Gelsenkirchen has found that inflammation of beating weather by electrical Incandescent lamps can only enter if by some circumstance the lightbulb is damaged breaks, whereby the thread is retained. This possibility is all the greater if low-voltage incandescent lamps, which have relatively short and thick filaments, be used, such as B. ampen with electric pit safety lights.
In der beiliegenden Zeichnung bedeutet a die elektrische Glühlampe; dieselbe sitzt auf einer Spiralfeder b, welche das Bestreben hat, die Lampe nach oben zu drücken. Oben stößt die Glühlampe gegen den Reflektor c, welcher eventuell ebenfalls als Spiralfeder ausgebildet sein kann. Die Stromzuführung geschieht durch die Feder b und den Kontakt d. Das Ganze ist von einem Schutzglas e, welches durch die Stäbe f und den Deckel g gehalten wird, umgeben.In the accompanying drawing, a means the electric light bulb; the same sits on a spiral spring b, which tends to push the lamp upwards. At the top, the incandescent lamp strikes the reflector c, which may also be designed as a spiral spring. Power is supplied through spring b and contact d. The whole is surrounded by a protective glass e, which is held by the rods f and the cover g .
Wird nun die Glasbirne α durch irgendeinen Umstand zerbrochen, so drückt die Spiralfeder b die zerbrochene Lampe nach oben und unterbricht auf diese Weise die Stromzuführung bei d, wodurch der Glühfaden erlischt.If the glass bulb α is broken by any circumstance, the spiral spring b pushes the broken lamp upwards and in this way interrupts the power supply at d, whereby the filament goes out.
Da nach den stattgefundenen Versuchen beim Zerbrechen der Glasbirne zunächst der Glühfaden durch die plötzlich in den luftleeren Raum der Birne hereintretende, verhältnismäßig kühle und durch die Expansion noch weiter abgekühlte Luft erlischt, so kann eine Entzündung etwa vorhandener explosibler Gase erst nach dem Wiederaufglühen des Fadens stattfinden. Es vergeht mithin zwischen Bruch der Birne und eventuell Entzündung der Gase eine gewisse Zeit; dieselbe genügt vollkommen, um mit oben beschriebener Anordnung eine ' sichere Stromunterbrechung herbeizuführen und auf diese Weise eine Explosion zu vermeiden.Since after the attempts that have taken place when the glass bulb breaks, the first Filament through which suddenly enters the vacuum of the bulb, relatively cool air, which has been further cooled by the expansion, is extinguished, so an ignition of any existing explosive air can be made Gases only take place after the thread has re-glowed. It therefore passes between breakage of the pear and possibly inflammation the gases for a certain time; the same is completely sufficient to cope with the above Arrangement to bring about a 'safe power interruption and in this way to avoid an explosion.
Es kann naturgemäß anstatt der Druckfeder auch eine Zugfeder verwendet werden, wobei die Anordnung sinngemäß geändert wird.Of course, a tension spring can also be used instead of the compression spring, the arrangement is changed accordingly.
