 das Wasser nur tropfenweise in den Karbidbehälter gelangt. Wird die Wasserzufuhr durch Niederschrauben der Stange h und Anpressen des unteren Kolbenventils go au seinen Sitz unterbrochen, so wird gleichzeitig die Verbindung der Röhre c mit der Aussenluft hergestellt, so dass durch   Nachentwiokjung   entstehendes Gas ins Freie entweichen kann. 



   Um die Laterne zur Abgabe von Signalen geeignet zu machen, ist an der   Rückseite   der mit einer Öffnung u versehenen Laternentüre v ein mittels eines Druckhebels   öffenbarer Moment-     verschluss   vorgesehen. Dieser besteht aus zwei halbmondförmigen, um einen gemeinsamen Zapfen w drehbaren Blendenteilen x   ? ,   die durch ein unter dem Druck einer Feder y stehendes Gleitstück   z in bekannter   Weise in Schliessstellung gehalten werden. Durch Verschiebung des   Gleitstückes   mittels des der Feder y entgegenwirkenden Druckhebelsj wird der Verschluss ge-

 the water only gets into the carbide container drop by drop. If the water supply is interrupted by screwing down the rod h and pressing the lower piston valve go into its seat, the connection of the tube c with the outside air is established at the same time, so that gas produced by post-development can escape into the open.



   In order to make the lantern suitable for emitting signals, a momentary lock which can be opened by means of a pressure lever is provided on the rear side of the lantern door v provided with an opening u. This consists of two crescent-shaped diaphragm parts x? Which can be rotated about a common pivot w. which are held in the closed position in a known manner by a sliding piece z under the pressure of a spring y. By moving the slider by means of the pressure lever j counteracting the spring y, the closure is

Claims

On acetylene lanterns a valve device which, in one position, allows the dropwise supply of water to the carbide while closing the carbide container from the outside air; Water chamber made possible, characterized by a double piston valve g, gl, which can be raised and lowered in a tube c connected to the carbide container and carries a piston extension k which dips with little clearance into a cylinder d connected to the water chamber, depending on the position of the double piston valve of these cylinders is completed and EMI2.2
