CONTROLLING SYSTEM FOR RAILWAYS.
Specication of Letters Patent.
Patented Sept. 10, 1907.
Application led March 2l, 1907. Serial No. 363,755.
To all whom it may concern:
Be it known that I, MAX TRAUTMANN, a subject of the King of Saxony, and residing at Dresden, Saxony, Germany, have invented certain new and useful Im- 5 provements in Controlling Systems for Railways, of which the following is a description.
The present invention relates to a railway controlling-system, in which a series of conductors divided into two groups and corresponding to the number of passing trains, is arranged, which conductors lead from the line to indicators and, at the place to be controlled, are put in circuit by suitable line-contacts operated by the passing trains.
The novel feature of the invention consists in that l5 the seri'es of conductors are arranged in two groups in such a manner that the one group receives current when the train departs from a station, the said current freeing the indicator-drops by means of electromagnets so that they drop down against the action of a spring or their own weight, while the said indicator-drops close special circuits, provided at the places to be controlled so that readjusting-magnets are lpermanently excited and keep the indicator-drops in their dropped-down position. The other group receives current at the next station when the train arrives there, and this current interrupts the circuit closed by the indicator-drops by means of electromagnetic switches, so that said indicator drops return to their initial position again.
In the accompanying drawings, Figure l is a diagram, showing the electric railway controlling-system in connection with the railway-line and Figs. 2 4 are details of the controlling-system.
A, B and C indicate switch-systems of the kind as used in telephony, which are arranged at those places at which the trains are to be controlled, as, for instance, at stations, at switch-mens houses or similar places.
4, 5, 6 are conductors, to which'the said switchsystems are electrically connected. The said conductors are arranged in both directions along the tracks of the railway-lines to be controlled. I, 2, 3 are dropdevices, which are connected with the conductors 4, 5, 6 of the switch-systems, and the number of conductors and drops correspond to the number oi trai-ns passing over said line. The example shown in the drawings comprises three trains.
Each of the drops l, 2, 3 of the-switchsystems A, B, C is, on the one hand, connected with one of the conductors 4, 5 and 6 of the track G and, on the other hand, with the common line 7, which latter is in conductive connection with a current generator 8 provided at a suitable place. In case the three dropsystems are arranged far from each other, then every drop system may have its own current generator.
9 and l0 are two contact-springs, which two springs are provided under every single drop of the switchsystem, and insulated from each other. The springs 9 are in Contact with the conductors 4, 5 and 6, while the springs l0 are," by means of lines 11,112, I3 each connected with relays 24, which in turn are connected with relays 25 and thus earthed by the common line wire 26. At the controlling-places of the line in question, for instance, at stations, contact-devices H and J are provided near the track G, of which contactdevices the one, J, is installed at the side of arrival, and the other, II, at the side`oi departure. The said contact-devices consist oi two posts 14 and I5 parallel to each other. The posts l5 are electrically connected with the ground, while the posts I4 are insulated. At the said posts 14 contact- springs 16, 17, 18 are mounted one below the other and insulated. These springs extend with their free ends over the posts l5, but in their initial position do not touch the same. The springs 16, 17, I8 of the contact-device are connected to the conductors 4, 5, 6. Likewise the springs 16, 17,18 oi the post .I are in connection with cable lines 20, 2l, 22, which are also provided along the track G and led to the electromagnets D, E, F oi the said relays 24, 25. These electromagnets, by means of a common line 27, lead with their other pole to the same pole of the current generator as the drops-system l, 2, 3 by means ci the line 7,
The mode'oi operation of the controlling-system is as follows z-Prior to the departure of every train a contactlever I9 (Fig. 4), arranged sidewise at the engine, is adjusted in such a manner that, if the train leaves the first station, one group of the contact-springs of the contact-devices H and J, or instance, the springs I6 are touched by the said contact lever I9 and pressed with their free ends against the post I5. Circuit is then closed and the current flows from the current-generator 8, over earth, post 15, spring I6, conductor 4 along the track G to the electromagnet-coils 23 ci the drops l and back to the current generator 8 over the common line 7. The electromagnets attract theirarmatures 30 (Fig. 2) and release the drops, to fall into a horizontal position, while normally i. e. if the armatures 30 are switched off, the drops are kept in a, vertical position owing to the weight ci the said armature. The dropped-down drop I of the system A connects in its horizontal position the contact-springs 9 and l0 and so closes a second circuit, which, flowing from the one pole of the current generator 3 over the common line 7, coils 23 oi all drops l, springs 9 and I0, line Il, relay-spring 25 of the magnet D and line 26, returns to the other pole of the currentgenerator. By this circuit the magnets 23 are permanently excited and keep the drops in their horizontal position. Now, when the train arrives at the next station the contact lever 19 will press the spring 16 against the post 15 ths dosing a new Cil-Cuib The Current i for electrically connecting the lines of one group with those' iiows now from the current-generator 8, over earth, post 15, spring 16, line 20 to the electromagnet D and returns over line 27 to the current generator 8. Consequently the electromagnet D will be excited and its armature 28 attracted, so that the contact at the relay 25 will be interrupted and the electromagnet without current, so that now the drops return to their vertical positionl owing to the weight oi the armature 30. 1f the train starts, it influences again the contact-device H so that the operation just described is repeated, and ii the train arrives at the next station those operations will be repeated, which took place at the arrival oi the train as above described.
Now, in order that the otlicials at the several controlling places may be informed, in which block-line the train is at the time in question, every drop is provided with an indicator. For this purpose over each drop of A, B and C there are arranged two contact- springs 32 and 33, which are connected with the said drop by a movable contact-piece 31. The rst contact-spring 32 is earthed, while the other contact-spring 33 leads to a line 35, connected with the current-generator 8. 34 is an electromagnet, which is arranged in the said line 35. The movable armature 36 of the said electromagnet 34 carries a pawl 37, which engages a step-wheel 39, rotatably mounted upon a stationary spindle 38, the said pawl 37 being designated to move stepwise the said stepwheel 39 opposite to an indicator 40, rigidly fastened upon the said spindle 38. That side oi the step-wheel 39 which is in iront ot the indicator 40 is provided with a scale, consisting ot division lines and iigures, which are arranged in the present case so as to correspond to the daily to and from traffic of six trains on the said line.
As soon as a drop falls down, the step-wheel 39 is advanced for a division line corresponding to one station in that the said drop establishes connection between the movable contact-piece 31 and the spring 32, whereby the circuit, containing the electromagnet 34, is closed, the armature 36 consequently attracted by the said electromagnet and thus the stepwheel 39 advanced, so that the figure just under the indicator 40 shows where the train in question is at the said time. When the said drop slides off from the contact-piece 31 it returns to its initial position owing to its own weight, so that the circuit in question is opened again.
It is thus evident that the electric-indicating-device shows, in which block-line the train is at the time in question, while the drops merely indicate whether the train is stopping at a station or is traveling. Other trains traveling on the same line will in the manner, as heretofore described, influence the springs 17 and 18 and the drop- devices 2 and 3, connected with the said spring by means of the lines 5 and 6 and consequently a special contact-spring, line, drop, relay etc. must be provided for each train.
