United Eisenbahn-Signalwerke G. mb H. in Berlin-Siemensstadt. Inductive driving lock in connection with daylight signals. Patented in the German Empire on October 19, 1930

With the inductive travel lock, the train is only to be influenced when the signal is on hold. This can be done with wing signals achieve that the circuit arranged on the route is led via a contact on the signal wing, so that by flipping it of the signal lever a contact in the circuit has been opened or interrupted.

The present invention relates to a simplification of this latter device, in such a way that a connection of the route circle with the signal box is saved. It is already known, individual circuits, z. B. the circuits of two signal lamps, to make them dependent on each other by placing a relay in a circuit, which is de-energized when the lamp goes out, drops tmd with the help of its Armature closes the circuit of the other lamp. It is also already known two To make signal lamps dependent on each other by inductive coupling. It is also already known, the detuning of track circles depending on signals with With the help of special relays, contacts or the like.

In contrast, the invention consists in the fact that in the present case the circuit the signal lamp makes this detuning directly via a transformer without the above-mentioned contacts and relays.

The subject of the invention is shown in the illustrations using various examples explained in more detail.

Fig. Ι shows an embodiment in which, in particular, the arrangement of a magnetic switch is saved. Here is z. B. a winding 8 of the transformer 9 is provided parallel to the capacitor 4, the second winding 10 of which is located in the circuit of the green lamp 7. As long as the contact 11 on the control lever 12 is interrupted, the transformer 9 has such a great resistance that practically only the winding 3 and the capacitor 4 are effective in the path circuit. If, on the other hand, the contact 11 is closed, the transformer represents a short circuit for the capacitor 4, and the line circuit is detuned so that it no longer affects the locomotive equipment.

The control transformer 9 can not only ' parallel to the line winding on the line capacitor, but can also be arranged in series with both. An example of this is in

Fig. 2 for the inductive control of the circuit by the circuit of the given red lamp. If the switch 17 for the red lamp 16 is closed here, it is the transformer 14 is short-circuited via its secondary winding 15, d. H. the route circle 3, 4 comes as a resonance circuit

Effect and influences the locomotive circuit i. If, on the other hand, switch 17 is open, so the winding 13 of the transformer 14 is an additional inductance with im Track circle 3, 4 and detuned this completely, so that interference is avoided will.

In all cases of inductive control of the coupling transformer with primary and secondary winding can also be replaced by a simple coupling inductance with only one winding that makes up the system of the route circle connects with the lamp circle. '

The track magnet itself with its pulse winding 3 can also be used as a coupling inductance or coupling transformer. In the latter case he receives after
Fig. 3 also shows a second winding 18, which is in the circuit of the green lamp 7 in the example.

In all cases the inductive control of the track circuit is affected also transfer energy from the locomotive equipment to the lamp circuit. Around It is useful to avoid the additional stress on the lamps caused by this Capacitors, inductors, resonance structures or the like. Be arranged. For example is in

Fig. 4 the lamp 19 connected in series with the inductance 20, while parallel thereto the capacitor 21 is located. In this case, the locomotive device 1 in AC energy transmitted to the lamp circuit finds its balance path via the capacitor 21 and not take over parts 19, 20.

In other parts of the circuit, too, the currents may be separated by electrical Sieves are brought about.

You can of course choose between the signal box and the facility that makes the connection with the circle of influence establishes, also special intermediate devices, such as transformers, control relays or the like. Use.

The invention can also be used where the position of the signals not from the signal box by flicking a lever, but where the signals can be controlled automatically by the train via the tracks.
