PATENT-ANSPRÜCHE : 1. Einrichtung an Grubenlampen zur Bestimmung des Sohlagwettergehaltes der Grubenluft, dadurch gekennzeichnet, dass an einem, den Lampensockel durchsetzenden Stift (6) Zeiger in verschiedener Höhe, eine Einteilung oder dergl. angeordnet sind, die im Bedarfsfalle in den Bereich der Flamme gebracht werden, so dass die Höhe der Aureole und damit der Prozentgehalt an Schlagwettern sicher abgelesen werden kann. PATENT CLAIMS: 1. Device on mine lamps for determining the soil weather content of the mine air, characterized in that pointers at different heights, a division or the like are arranged on a pin (6) penetrating the lamp base, which are brought into the area of the flame if necessary, so that the height of the aureole and thus the percentage of firedamp can be read off reliably. 2. Einrichtung nach Anspruch l, dadurch gekennzeichnet, dass die beiden Zeiger (7 und 8) an dem Stift (6) zueinander versetzt angeordnet sind und zugleich als Löschdeckel bezw. als Abstreifer für das abgebrannte Zündband dienen, wobei der Stift (6) im Sockel drehbar und EMI2.1 3. Einrichtung nach Anspruch 2, dadurch gekennzeichnet, dass der, bei in den Lampensockel eingeschobenem Stift über den Lampenboden herausragende untere Stiftteil (61) um ein Scharnier umklappbar ist, um denselben vor Beschädigungen zu schützen und die Lampe aufstellen zu können. 2. Device according to claim l, characterized in that the two pointers (7 and 8) on the pin (6) are arranged offset from one another and at the same time as an extinguishing cover or respectively. serve as a scraper for the burned ignition tape, the pin (6) rotatable in the base and EMI2.1 3. Device according to claim 2, characterized in that the lower pin part (61) protruding over the lamp base when the pin is pushed into the lamp base can be folded over around a hinge in order to protect the same from damage and to be able to set up the lamp.
