Claims (1)

Patent-Anspruch:Patent claim: Vorrichtung zum Signalisieren eines herannahenden Eisenbahnzuges bei geöffneter Wegschranke, bei welcher durch den Zug ein Alarmstromkreis geschlossen wird, dadurch gekennzeichnet, daß an die Alarmleitung (f) ein zweiter Stromkreis (n) angeschlossen ist, der durch das Niederlassen der - Schranke geschlossen wird, so daß ein eingeschaltetes Relais («) einen Anker (I) anzieht, hierdurch den Alarmstromkreis (/) unterbrechend.Device for signaling an approaching train when the barrier is open, in which an alarm circuit is closed by the train, characterized in that a second circuit (s) is connected to the alarm line (f) and is closed by lowering the barrier, so that a switched on relay («) attracts an armature (I) , thereby interrupting the alarm circuit (/).
