Schutzglas für elektrische Lampen, besonders Sicherheitslampen.Protective glass for electric lamps, especially safety lamps.
Patentiert im Deutschen Reiche vom 30. Januar 1910 ab.Patented in the German Empire on January 30, 1910.
Elektrische Lampen, welche in explosiblen Gasgemischen, z. B. schlagenden Wettern, beschädigt werden, können das explosible Gasgemisch anzünden. Ein Schutzglas verbürgt nur eine bedingte Sicherheit, da bei stärkeren Beschädigungen des Schutzglases auch die elektrische Lampe zerstört werden kann.Electric lamps which are used in explosive gas mixtures, e.g. B. beating bettors damaged can ignite the explosive gas mixture. A protective glass only guarantees a limited degree of security, since stronger ones Damage to the protective glass can also destroy the electric lamp.
Die vorliegende Anordnung an dem Schutzglase soll bezwecken, daß die Lampe stromlos ίο wird, sobald das Schutzglas so stark beschädigt wird, daß die Gefahr einer Beschädigung der elektrischen Lampe vorliegt.The present arrangement on the protective glass is intended to ensure that the lamp is de-energized ίο as soon as the protective glass is damaged so severely that there is a risk of damage the electric lamp is present.
In oder an einer schwachen Stelle des Schutzglases befindet sich ein Quecksilberfaden oder sonstiger leicht zerbrechlicher, elektrischer Leiter, welcher mit der Lampe so geschaltet ist, daß die Lampe stromlos wird, wenn der Leiter zerreißt.There is a mercury thread in or on a weak point in the protective glass or any other easily breakable electrical conductor that is connected to the lamp in this way is that the lamp is de-energized when the conductor breaks.
Bei angemessener äußerer Gewalt bricht oder trennt sich das Schutzglas an der schwachen Stelle, wobei der elektrische Leiter zerreißt und die Lampe stromlos wird, bevor sie beschädigt werden kann.In the event of appropriate external force, the protective glass breaks or separates on the weak point, whereby the electrical conductor tears and the lamp is de-energized before it can be damaged.
Um den Schaltfunken unschädlich zu machen, kann in bekannter Weise komprimierte Luft, Kohlensäure 0. dgl. unter der Schutzglocke eingeschlossen sein.In order to render the switching spark harmless, compressed air, Carbon dioxide 0. The like. Be included under the protective cover.
Die Anordnung kann beispielsweise so getroffen sein, daß das Schutzglas aus zwei oder mehreren Teilen besteht, welche mittels eines geeigneten Bindemittels miteinander verbunden sind, so daß sich die Teile des Schutzglases an den zusammengekitteten Stellen trennen, wenn äußere Gewalt das Schutzglas trifft.The arrangement can be made, for example, that the protective glass consists of two or consists of several parts, which are connected to one another by means of a suitable binding agent so that the parts of the protective glass separate at the points cemented together, when external force hits the protective glass.
Das Bindemittel kann selbst leitend sein oder die Leitung kann in oder an das Bindemittel verlegt sein.The binder itself can be conductive or the line can be in or on the binder be misplaced.
