To all whom it may concern:

Be it lgnown .that I, ALEJANDRO BASANTA Y BAQUE, a subject of the King of Spain, residing at Madrid, Spain, have invented an Electrical System for Signaling Between t'lrains, of which the following is a specificaion.

The object of my invention is to provide a simple and reliable automatic electric signaling system between trains for the prevention of collisions on railways.

In the accompanying drawings, Figure 1 is a diagram in the natureof a sectional elevation of a car on a railway-track to illustrate my invention. Fig. 2 is a diagram illustrating appliances and suitable arrangements of electric circuits for carrying my invention into efiect on two cars between which signals are to be transmitted; and Fig. 3 is a view similar to Fig. 1, illustrating a modification, and Fig. 3 a diagram showing the circuits in this modification.

In carrying my invention into effect I provide alongside the railway-track one or more electrical conductors divided into sections electrically separated or insulated from each other, these sections being of any desired or suitable length, such, for instance, as commonly adopted on block signaling systems. These conductors may be elevated at any desired height above the ground or laid on the surface'of the but should be insulated. On the locomotive or a car of each train I provide trolley or other contacts to make electrical connection with the above-mentioned conductors, and these contacts I connect up with one or more audible or visible signalsland a telephone set with a magneto-machine on each locomotive or car, the magneto-machine being belted or geared up to a car-axle orsome suitable moving part of the running-gear with means for disconnection. There is also provided on the car or locomotive an electrical switch for, changing the electrical connections, as desired. The electrical circuits on the cars or locomotives are grounded through the metal work of the frame, the wheels and railwayrails, or in any other suitable Way, so that when a railway-train starts in motion, as on leaving astation, the magneto-machine on the locoground or below the ground,

motive or car of that train will be automatically put into operation, and if there be a train within the same block-that is, a train having on its locomotive or car an electrical outfit such as described-with contacts making electrical connection with the same section of conductor or conductors along the track, the circuit will be completed through the ground between the two trains, with the result that the magneto-machine on the starting train will operate the signal on the distant train Within the electrical block and so give warning. If the signal on the starting train be included in the same circuit, as it should be, the starting train will likewise have notice given automatically that there is a train ahead on the same block. Then the engineers or guards on the two trains can put themselves in telephonic communication with each other over the same conductor along the track and be advised what to do under the circumstances.

While I do not wish to limit myself to any special construction of details for carrying my invention into effect I will now describe, with reference to the accompanying drawings, particularly Figs. 1 and 2, an arrangement of apparatusand circuits which may be employed.

As represented by Fig. 1 the insulated eonductors p 19 are carried by the strip P, which, in this example, is shown as supported upon posts 10 alongside the track and at a height just above the level of the top of the cars W. Brushes b b or other suitable contacts carried by the car make contact with the conductors and are themselves electrically connected up to the instruments on the car or locomotive, as described below.. One of the cars or the locomotive W of each train is provided with a magneto-machine M belted or geared to the axle A or other moving part of the car or locomotive, a signal-bell 0 so connected up that it will be put in operation by the current from the magneto-machine on another train, which is on the same block, a

bell 0 always in circuit with the magnetomachine on the same car, whereby the engineer or conductor is notified when the circuit is closed by another train coming or be ing on the same block.

In the same circuit with the signal-bells are telephonic instruments, and when the engineer or conductor receives a signal, or a reply on his signal-bell to a signal from his train, he connects up the circuits for talking over the telephones by switches S, which may be part of the telephonic mechanism and operated by raising the receivers. The current from the battery R passes through the microphone T and from the battery B through the microphone T.

The magneto-machine carries a fast and a loose pulley for the belt B, whereby the machine may be put into or out of operation at the will of the engineer or conductor. Each circuit is further provided with a fuse or cutout L placed near the contacts.

The circuits containing the signals and telcphonic instruments are grounded through the metal frame and wheels of the car and so to the track, so that if two trains come with their contacts I) b on the same block or section of the line, the electrical circuits will be closed through the conductors p p and instruments on the two trains and the ground connections. By this arrangement two trains cannot be on the same block, and either or bothbe in motion without each being notified of the fact, as will be seen by following the circuits.

Referring to Fig. 2, when the car W moves, the magneto-machine M is set in motion by the belt 13 and the axle A of the car. The switches S S are normally in the position shown in full lines in this Fig. 2.

If another car W is on the same section or block with car W one pole of the magnetomachine M on the car IV being grounded through wire 10 and the metal frame and wheels of the car, a current flows from the other pole of the magnetomachine M, and conductor 1, through the electric alarm-bell C and through the wire 2 to the switch S, and thence through the wire 3 and cutout L and connection 4: to the main line. On the other car W the current from the main line enters through the connection 5, cut-out L and passes along the wire 6 to the switch S, then through wire 7, alarm-bell 0 wire 8 to the magneto-machine M, thence to the ground through wire 9 and the metal frame and wheels of the car. The alarm-signal is thus produced in both cars at the same time, both alarm-bells O 0 being in the circuit.

If the engineer in car W wishes to speak to the engineer in car W, he turns the switch S into the position indicated by dotted lines in Fig. 2, and the current from the magneto-machine M will then pass through wire 1, alarmbell 0, wire 11, switch S, wire 12, cut-out L, wire 13 to main line, wire 14: in car W, cutout L, wire 15, switch S, wire 16, telephone call-bell 0, wire 17, telephone apparatus T, wire 18 to ground.

\Vhen the engineer who has been signaled turns his switch S over to the position indicated by dotted lines,both telephones will be in circuit, as follows: from the ground wire 22 on car W to the telephone '1, wire 21, callbell 0, wire 23, switch 8, wire 3, cut-out L wire 4 to main line, wire 5 in car WV, cut-out L wire 6, switch S, wire 24, call-bell (3, wire 17, telephone T, and wire 18 to ground.

While the telephones are being used the current from the magneto-machines may be cut off by any suitable means, as by throwing the belts over to the loose pulleys. In that case both alarm-bells C C are still in circuit, so that they will ring if a third car en ters the same section.

As it is not always necessary that trains going in both directions have their magneto-machines in operation, inasmuch as the signalbell is always in circuit with another train on the same block, I also provide a detachable handle to operate the magneto-machine by hand when desired.

The signaling and the telephonic communication may be made with a single conductor or metallic strip along the line, as illustrated, for example, in the drawings, Figs. 3 and 3. In this case the line conductor is a metal strip 19 fixed upon porcelain insulators I, supported upon wooden or iron posts P alongside the track at a height just below the steps to of the car W A metallic roller b moves along the strip and is fixed to the step of the car by means of two springs y y. When the car moves, the electro-magnetic machine M is operated by the pulley m belt B and axle A and the current flows through the electrical bell 0 wire 21, roller 1) to main line. The circuit can only be completed through another car on the same track.

In Fig. 3 M represents the electromagnetic machine, from which the current flows through the wire 31, bell G connection 32, lever O of the telephonic apparatus, and connection 33 to main line. The magneto-machine is grounded through the line 34:. The circuit is completed through another car on the same track, and when one of the trains is in motion the signal is given in both trains.

\Vhen the engineer on guard lifts the receiver K the lever O is turned on its axis 0 and the connection at Q broken and at 35 36 37 are established. The battery R is then in circuit with the microphonet and inductioncoil t. The circuit is now from the main line, connection 33, lever 0, connections 35 38 to the ground.

I claim as my invention An electrical system for signaling between trains, comprising insulated conductors in sections, a magneto machine carried by each train and means whereby said magneto-machine is set in motion by the movement of the train, contacts carried by each train to make contact with the said conductors, telephonic apparatus and signal bells and a switch carried by each train to throw the telephone apparatus or the signal bells to line and conn ections whereby at the moment of closing the name to this specification in the presence of circuit between two trains going either in the two subscribing witnesses. same direction or in opposite directions the two trains will receive a. signal at the-same ALEJANDRO BASANTA Y 5 time and telephonic communication estab- Witnesses:
