To all whom it are concern:

Be it known that I, CLARENCE CLAUDE TURNER, a citizen of the United States, resident of the city of Portland, county of Multnomah, State of Oregon, have invented a certain new and useful Improvement in Automatic Signaling and Train-Stopping Combination Circuit Devices.

My invention relates to automatic signalingr and stopping devices for railway vehicles and train of vehicles, equipped either with electric motors or steam, or other 1000- motives for propelling, and with air or electric or other automatic brakes for retarding and stopping same, and is a division of m application, Serial No. 699,946, filed Mhy 27, 1912.

The general object of my invention is to a provide a safe and reliable automatic means of performingindependently of the motorman or locomotive engineer some of the functions he is usually expected to perform while in charge of his vehicle or train, but which he may for anyof various reasons, be unable to, or neglect to perform.

Railroads equipped with trains operated by steam locomotives, or as in case of interur'ban electric lines, by motor cars, usually have their roads divided into blocks, each block being provided with signals, the purpose of these signals being to show the line clear, or otherwise in the block, or section immediately ahead of the signal shown.

Should the signal ahead ofa moving train show danger the engineer or motorman would ordinarily shut oil his propelling ower and apply the brakes, but should he or any reason fail to do so, my invention is devised to operate automatically in combination with any electro-lnechanical railway signaling systein, or independentlyso thatpart of an electric circuit connecting wlth a third rail is closed in such a manner that when certain electro-mechanical contrivances on the moving vehicle, as for instance those described in my application #699,946, come in contact with the aforesaid rail, they areautomatically putinto operation and shut oil the propelling forces, and apply the brakes.

The figure shows the plan of a railroad track fitted with the third rail autoy application will matic signaling and train stopping combination circuit device as arranged to work in.

combination with my invention as described ing a completed electric circuit to put it into co operation.

To describe my device more in detaihl are short sections of third rail laidin close proximity to-and parallel with the main track rails, having their top surfaces several inches above the level of the surface of the main track rails and insulated from same and from the ground. The top surface of this third rail is curved slightly downward at the ends so that the roller 2 readily ride upon said rails.

1 are single sections of main line rails insulated at each end from the rest of the track by suitable insulators 1 so that they,

have no conducting connections with the rest of the railway track.

4 are insulated electric wires connecting the third rails 1 to the contact points 4: of

electric relays 14, 15,16, 17, 18, 19, 20, 21,

22, 23, 2a, 25, 2c, 27, 2s, 29.

5 are insulated electric wires connecting the insulated rails 1 with the armatures 6 of the relays.

B, C, D, E, F, G, H, are adjoining track signal circuit sections.

7,8, 9, 10, 11, 12, 13, track signal circuit batteries one to each section of track respectively. 10 for instance is the track battery for section E, the iower rail of which in the drawing is wired to one binding post of relay 19 the upper rail is wired to one binding post of relay 24 the other binding posts of said relays are connected by a con duotor thus putting these relays in series with each other and track battery 10. These conductors connecting the relays to the track rails are attached to the rails at the o posite end of the section to the conducto s connecting ,To describe the operation of my invention we will assume a train traveling in the direction of A from the right and that it has entered section E; the conductors from the in my former 70 the battery to the track.

track to the relays 19 and 24 are connected to track rails in close proximity to the rail insulators 1" so that when the front wheels and axle of the engine have entered a short distance into section vE they short circuit the battery 10 circuit; the effect of this short circuit is to deenergize the relay magnets 12 i and 19, this releases'the armatures 6 of said magnets allowing them to spring back and contact with the contact points 4: bondmg the third rail to the insulated rail section 1 between F and G and also between C and D. This sets the third rail combination between F and G and that between C and D namely those combinations now controlled by relays 24 and 19 respectively; so that any vehicle or train fitted with the invention described in my application, Serial No. 699,946 or any other similar contrivance requiring the closing of an income plete electric circuit to put it into operation; approaching the section E from the right of the drawing will be automatically stopped as the roller 2 (see Fig. 1 application, Serial No. 699,946) contacts with the third rail 1 between F and G as also any train approaching section E from the left side of the drawing will be automatically stopped in a similar manner by said roller 2 or other similar contr'ivance cont-acting with the third rail 1 between C and D. The train on section E is thus protected from both ahead and behind. It will be clear to anyone familiar with the art of railway signal ing that the third rail combination above described may be set in a variety of ways, but the above description will be sufficient to show the great value of this contrivance as a preventive of railroad headon collisions or rear-end collisions or as a means to readily cont-r01 the movement of trains at a great distance from the signal operator. It is clear that it can be adapted to work in combination with a regular block signaling system or with its own independent batteries or circuits.

What I claim as new and desire to secure by Letters Patent is 1. In an automatic signaling and train stopping combination circuit device of the character described, the combination with track batteries, track relays arranged in pairs and their circuits of a track having a short insulated section for each pair of relays, an insulated conductor which 'forms a conducting connection between the section of insulated track rail and the armatures of the corresponding track relays, a section. of insulated third rail which is laid in close proximity to and parallel with the insulated section of the main track rail a second insulated conductor and contacting points connected by the aforesaid second insulated conductor to the aforesaid section of insulated'third rail, and arranged to contact with the aforesaid relay armatures when they are released by. theirrespective magnets.

2. A single track system of train control comprising a track having one rail divided by insulated joints into block sections and the other rail divided by .two insulated joints at the end of each block into corresponding block sections with relatively short sections separating the block sections, a coritact rail paralleling each short section, connections between each short section and the corresponding contact rail, two magnets for each contact rail controlling said connec trons one'of the magnets of any contact rarl' being connected with the track rails of the second block in one direct-ion from the contact rail and the other magnet belng con nected with the track rails of the second block in the oppositedirection, and a battery connected with the rails of each block section.
