Patented in the German Empire on September 22, 1906.

The invention relates to a device for triggering a signal on the moving vehicle Train in which the warning signal is interrupted by a normally closed Circuit is triggered from the track, if not the interruption is prevented by a second circuit when the route is clear.

There are already various institutions

ίο became known when driving over a contact rail located on the route, a warning signal on the locomotive is triggered. In these facilities, however, must be a forceful touch of the stop on the locomotive with the Distance stops take place so that the contact surfaces are bare enough to get a To cause a short circuit. Due to the strong friction on the surfaces, however, will not only the surfaces themselves are worn, but there is a strong resistance to the current. As soon as the stops are covered with ice, dirt or rust, even if the contact surfaces are touched vigorously often no circuit can be closed. In the invention, the highly stressed Currents of a spark inductor used, which at certain points on the track, be it with or without track stop, can be closed and thereby cause a warning signal.

In the drawing, the subject of the invention is shown schematically, namely shows the figure shows an embodiment of the device on the locomotive in the rest position.

The primary coil 3 of a spark inductor is connected to the current source D by the line 2, 4 in which the interrupter is located. The circuit of the secondary coil 10 of the spark inductor is usually interrupted by the coherers C, C ¹ , the spark gap 6, 7 and by the brush 8, which is isolated on the underframe of the locomotive. The secondary circuit is closed by driving over a contact rail located on the track with a line signal, the sparks jumping from line 6 to line 7 and thus making the coherers for a circuit via the electromagnet E conductive. The current then goes from the current source D via line 4, 11, coherer C, C ¹ , line 12, electromagnet E, line 13 back to the current source D, whereby the electromagnet E attracts its armature 14, which is rotatably mounted on the housing of the device at e as a result, the closed circuit at E ² , which is fed by the current source D, is interrupted. E ^ lets go of its armature 21, whereupon the spring-action disk 23 rotates in the direction of the arrow until it is blocked by the pin 24. By rotating the disc 23, which is seated on the pin of a valve, for example, in the direction of the arrow, the brake is activated or the steam whistle is opened. The disk 23 is brought back into the initial position by hand and the circuit via E is interrupted by tapping the coherers, so that the disk 23 is automatically locked again and the device thus returns to the rest position of FIG. 1

got. The tapping of the coherers C, C can also be done automatically in a known manner instead of by hand by the disk 20 z. B. is rotated by the shaft of the dynamo by means of a suitable translation in the direction of the arrow, whereby the coherers mounted on the leaf springs / on the housing are knocked off alternately. This means that in the event of a fault in the facility, always a

ίο a warning signal is given, the locking electromagnet E ' ^{2 is placed} in the permanently closed primary circuit, so that ζ. Β. if this circuit is interrupted, the locking armature must always drop and the signal must sound.

A polarized relay can be used in place of the two electromagnets E, E ³ and an electrolytic detector can be used for both coherers. In the secondary circuit, an explosion device, e.g. B. a blast cartridge are located, which gives the warning signal. Since a spark inductor can easily become too warm during long periods of operation, it is advisable to use two of them, in such a way that one or the other spark inductor is alternately connected to the power source by means of a rotating switch. It is useful to attach a contact rail to the locomotive, which is located within the boundaries of the clear space, while several brushes separated from one another along the length of the contact rail are attached to the route. These brushes only need to touch the contact bar lightly and can therefore consist of tufts of wire or the like, which prevents the stops from breaking due to the train.

If the warning signal is not to sound when a contact rail is crossed, the closed circuit in which the electromagnet E ' ² is located must be kept closed, despite the fact that the current closed via the electromagnet E wants to interrupt this circuit. This happens because ζ. B. in the driving position of the route signals in a known manner a special electromagnet E ³ is excited by electrical waves, through whose armature the closed circuit of E " ² is performed.

Claims (1)

Patent claim: Device for triggering a warning signal on the moving train, in which the signal is triggered by breaking a normally closed circuit from the track, when does not prevent the interruption by a second circuit when the line is free is, characterized in that the signal circuit is interrupted when driving over current circuit rails on the line by closing the secondary circuit of a spark inductor in this coherer switched on are made conductive and thereby an excitation current through the breaker magnet of the signal circuit let go while "in the driving position of the Line signals The signal circuit is closed by a special magnet is held, which is excited in a known manner by electrical waves. 1 sheet of drawings.
