To all whom it may concern:

Be it known that I, ANATOL .GOLLOS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, hareinvented certain new and useful Improvements in Track Apparatus for Signal or Stop Systems, of which the fol lowing is; a specification.

The use of an intermlttent third rail, or

contact rail as it is more commonly called,

in connection with railway signal systems or stop systems, has heretofore been proposed or adopted. Ordinarily these contact rails or contact members comprise relatively short sections, usually arranged adjacent to the end of a block and supplied with a feed wire whereby the railmay be energized, these rails operating in conjunction with contact shoes or contact devices arranged on the car or locomotive. An objection to the usual arrangement of such contact rails and track circuits as heretofore arranged has been that the contact rail might become torn out entirely, or moved to such an extent that the contact shoes would not touch the same, without affecting the system so that a warning would be given of the dis placement of such rail.

The principal object of the present invention is to arrange the wiring of the track system so that the tearing out or displacement of the contact rail will act upon the track circuits so 'thata proper warning or signal will be given.

I have illustrated my invention in the accompanying drawings in which,

Figure 1 is a diagrammatical view of a track system embodying this invention; Fig. 2 is an end view of an undercontact rail showing one method of securing a circuit wire thereto; Fig. 3 is a side view of the parts shown in Fig. 2; Fig. is an end view of a contact rail for an overrunning contact shoe showing the circuit wire attached thereto; and Fig. 5 is a side View of the parts shown in Fig. 4.

As indicated in these drawings, 6 represents one of the track rails which is insulated at the ends of the blocks, and 7 represents the other rail which is continuous. Each block is provided with a track battery 8 which is connected to the rails "6 and 7 by wires 9 and 10 adjacent to the exit ends is intended for a double track road with,

the trains moving from left to right as in cheated by the arrow, two stations A and B being shown. The apparatus at stationA only, will be described, the corresponding parts at the different stations being lettered to indicate their location. One of theter- .minals of a relay 11 is connected by means of a wire 12 to the rail 7, the other terminal 7 is connected by means of a wire 13 to the rail 6 at the right of the station. One of the switches or contacts 1 E of the relay 11 is connected by means of a wire 15 to. the

wire 12. Such switches or contacts are commonly designated as the relay armature which term will be used hereinafter for such contacts. ture is connected by means of a wire 16" with a battery or other suitable source of electricity 17 The other terminal of this battery is connected by means of a wire 18 to the second armature of the corresponding The other terminal of this arma in normal condition the relay ll receives current from the battery 8 adjacent to station B, the circuit being as follows: from battery 8*, wire 9, rail 6, wire 13, relay 11, wire 12*, rail 7, wire 10 back to battery. As long as the circuit remains closed the re lay will be energized which will hold its armatures closed so that the contact rail :21

.B, or if the circuit from the battery to the relay is interrupted, the relay would drop and would open the circuit to the contact rail.

I do not herein claim this general system,

connection between the contact rail 21* and the system except through the Wire the contact rail could be torn out or' displaced without in any Way affecting,thebalance.of

the system, and if a train passed the block Where the rail was torn out or displaced it would receive nowarning. signal or would notbe stopped. In order to overcome this objection l carry the W1re '12? alongside the rail in and secure it thereto in any conenient manner so that if the rail is torn aivay or displaced itwill break the Wireand thereby open the circuit from the track battery to the relay 11. If desired, a frangible link or other connectorsuch as indicated at 22 may bearranged in the wire 12 =so that it Will be broken instead-of the Wire. It will be seen that: when the relay opens, it will open thecircuits through both of its arma tures and will thereby deenergize the contact rail at the next station to the left. Forinstance, if the relay 11 is opened the contact rail 21" Will be deenergized on, account of opening the circuit through the armature 14%, This Will cause a train approaching from the left to be stopped: 01: signaled at the next station to the one Where the contact rail is torn out or displaced and: the engineer or operator may then proceed under caution or according toproper train. rules until. the difiiculty is located.

When an under-contact rail, such as indicated at in Figs. and 3 is used, such rail is usually protected by a ooden'box or cover 24s.- In this instance, the Wire 12 may be carried along theside of the box and. held in position by means of a molding 25.

lVith an over-contact rail, such as indicated at 26 in Figs. and 5, blocks 27 may be secured to the eb of therail at intervals and a molding 28 attached tothese blocks for receiving the wire 12 It will bereadily apparent that various methods may be used for securingthe circuit \vireto the contact rail Without departing from the spirit of this invention. Furthermore, my improved arrangement may be used with other track systems employing contact railsand having suitable track circuits, the presentsystem being merely illustrative of thegen eral arrangement.
