UNITEDISTA (PATIENT, or fice;

HENRY Q'BENNEQKE, or CHICAGO, ILLINOIS.

-To all whom it may concern:

.Be it known that L'HEXRY BENNEGKE, I

a-citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new andvuseful lmprm'ements in Railway Signaling Systems, of which the following is a specification.

The invention relates to signaling systems for railways and more particularly for elec .trically operatedrailways, and seeks to provide a simple and elieetive system by which trated in the accompanying drawing, and

more particularly pointed out in the appended claims.

Figure 1 is a diagrammatic view of the improved system, the equipment for two separate cars or trains heing represented. Fig. 2 is a diagrammatic section of the railway line.

As stated, the inrention is particularly applicable for use in connection with electrically operated railways. 'll1e tracks 10 form continuous main conductors for one side, usually the negative side, of'the opcrating circuit fonthe car-motors. A'trolley rail or wire 11 forms a continuous conductoiyfor the opposite or positive side of the power circuit; The conductor for the positive side of the power circuit shown in Fig. 2,'is in the form of an insulated'third rail-11 arranged in usual manner'at one side of the track; provided with a suitable trolley or shoe 12' which is connected by aconduc'tor 13,

- circuit breaking switch 14 and a conductor 15 to one pole of the "motor 16'which is arranged in any. suitable or usual manner 'to propel the car. The opposite side or pole of the motor 16 is connected to the- 1 racks or negative conductors for the power eifiuit by a conductor 17, wheel axle '18 and car wheels 19 that runon the track. The

motor circuit is provided with any suitable form of controlling switch (not shown).

In acco dance with the present invention Each car 'or train is RAILWAY SIG NALING SYSTEM.

a pair of supplemental, orfsignaling conduetors 20 and 21extend along the railway' line, These conductors are insulated and ma be of any suitable construction, In the or'm illustrated in Fig. 2, these conductors comprise supplemental rails arranged between the main rails 10 and are mounted on plates 22 fixed .to the ties or, other'fouiidation structure. plates 22 by wooden supports or rialils; 23; These wooden insulating supports 'iire pro vided with projecting side flanges 24; having inclined outer 'faces and. repesse'd lfower faces, as shown in Fig. 2, to; preventthe short, circuiting of thesupplempntalfrails 0

The supplemental 'zeoncluctors 20 .;'and 21 are divided into sections or blocks is ind1- cated in Fig. 1, and'each section of the conductor E20 isconnected, to the section, of the conductor 21 in the nei\ t adjacent blocks by cross conductors 25. at all dangerpoints along the railway line, such asiswitches,

crossings and the like, a normally open switch. is interposed between the supple' e 1s. Ir-- rangcd to be shifted to closed position when the line at that'point is not cleaifiln Fig.

semaphore signal 27 at this point is ranged to shift a normally openjswitcli Q. lhis switch and its contact- 2! are connected by conductors 30 to the signaling 'conducQ tors or

rails

20 and 21. The switch rails 26 are also arranged to operate a normally open switch 31 by means of-a sirtable-connectio'n 32, and this switch at its'contaoc33 is connected by conductors 31 and 30 to the signaling railsor conductors and 21 I Besides the main

traveling contacts

12 and 19 which engage the main conductors 11 and 10 of thepower circuit, eacligcar or train is provided with a pair'of supplemem tal traveling contacts 34 and 35 whiohiar'e in the forinof suitable brushes or sh es-and 'which are suitably supported from he car? body 36 in position to engage tl supple-j mental conductors or rails 20 and The signaling and safety equipine'nt, of each car or train comprises a n el'ectric bell 37,2111 incandescent lamp 38-ai1 fl an eleetromagnet 39. The operating circuit for these parts, in the preferred arrangement, de-

The rails are insulated fromlhe drives current from the motor circuit and;

comprises a pair of branch conductors on each car connected respectively to the two main contacts of the car and connected to the two supplemental contacts of the car by a second air lam and magnet are arranged in multiple blades 48 and in t e signaling circuit. One pole of each of these parts is connected to the negative conductor'17,of the 'motor eircuit by the

conductors

40, 41 and 42. The other holes of the bell, lamp and magnet are connected by the conductors 43, 44 and 4,5 to a conductor 46 that is connected to two dia onally opposite poles 47 and 47' of a doub e pole, 'double throw, pole-changing switch. The.

49 of thisswitch are connected by conductors 50 and 51- to the supplemental contacts or brushes 34 and which'engage the signalin conductors or

rails

20 and 21. The two iagonally. opposite poles 52 and 52 of the switch are connected by conductors 53 and 54 to the positive conductor 13 of the motor circuit.

The. conductors 42 and 53 are arranged in the manner usually employed to form an electric lighting circuit by which the car or train is i1 uminated. As shown, a series of incandescent lamps 55 are interposed between the conductors 42 and 53 and a resistthe poles 47 and and 52, in accordance with the direction ance 56, inter osed in the conductor 53, properly cuts own the \amount of current supplied to the supplemental lighting or' s gnahng circuit. The present improved signaling equipment-for a car or train is thus adapted to be connected direct to the electric lighting circuit now in common use.

A resistance 57 is preferably interposed in the conductor 43 leading to the bell 37, since less current is required to operate the bell than to operate the lamp 38 or the magnet 39. The elcctromagnet 39 is preferably in the form of a solenoid and its core 58 is connected by a link 59 to a pivoted lever 60. This lever is connected by a link 61 to the circuit opening switch 14 and to an armfil which operates the controlling valve 63 0f the air-brake system on the car or train.

in the diagram Fig. 1, the blocks formed by the rail .

wtions

20 and 21 are numbered 1, 2, 3 an"! "t. The equipment for two cars or trains A and P are represented as running on the same track formed by the rails 10. The blades of the pole changing switch of each equipment are engaged either with 52 or with the poles 47 in which the car or train is movin". If it be assumed that the cars or trains A and B are moving. in the direction indicated by the arrows, the pole changing switch on each car will be in engagement with the poles 47 and 52, as shown. As represented, the car or train A is in block No. 2 and car the brush 35 and rail 21 of block the power is cut off car A, through resistance 56,"conductors 53 and 54 to the terminal 52 of the switchpv thence by Switch blade 49, conductor 51 to No. 2 thence by the cross connection 25 to the con ductor 20 of block No. 3. If the next following train is in block No. 4 the circuit will be broken at the gap between the rails 20 of blocks Nos. 3 and 4, but if the car or train is in block No. 3, as shown, the circuit I will be completed as follows :-from rail 20 to brush 34 and conductor 50 of car B to the switch blade 48 and terminal 47 and by conductors 46, 43, 44 and 45 to the bell 37,

lamp 38 and magnet 39, and from these parts by the

conductors

40, 41, 42 and 17 to the wheel axle 18, wheels 19 and tracks 10 which form the negative conductor of the power circuit. The completion of this circuit will thus by the audible and visual signals 37 and the engineer or motorman o the car or train B. At the same time the solenoid 39 in. car or train B will be energized and the switch 14 shifted to open position, so. that the car. The brake lever. .62 will also be shifted automatically to apply the brakes to the car or train. As soonas the car or train A advances into block No. 1- the sig- 38 indicate dan 'er ahead to from the motor 16 of naling circuit will be broken at the gap be tween the rail sections 20'of blocks Nos. 2 and 3 and the circuit throu h the bell 37, lamp 38 and magnet 39 of car'or train B will be opened and the engineer or motorman of this car that he nay safely proceed. If the trains A and B were traveling in the. direction the reverse of thatindicated by the arrows and occupied -similar positions the bell, lamp and magnet of train A would be operate in a similar manner. The signaling and safety devices in any car or train are thus operated whenever there is another car or train in the next'adjacent block ahead, but

the signaling-and safety devices in the lead-- 1 15 mg car or train are not affected.

As stated, normally open switches, such as the switches 28 and 31, are arranged at danger points along the line and are closed when the line is not clear. are interposed between the

block conductors

20 and 21. If any car or train enters a. block in which. one of these switches is closed the signaling and safety devices thereof are operated. For example, in the diagram car A is represented as being in the same block with the switches 28 and 31 which are in their closed or danger positions. Under such circumstances current willflow as follows:

or train will be notified 105 These switches 120 fromthe positive j power condiictor Il -1 :throulilthe trolley 12:

through

conductors

40,41, 42 and 17 to the traveling contactwheel l9'and the I negawith ma in tive power conductor or track 10. The power circuit to the motor 16 of car A- will then be opened by. the circuit breaking switch 14, the brake-controlling valve 63 will be operated,- and the

signals

37 and 38 indicating danger'ahcad to the motor-man or engineer of car or train A; These signals will remain at danger-until theline is' clear and the switches 28'and 31 restored to their-normal open position,

\Vhile the preferred arrangement 'is 'set forth and illustrated it will be understood that the detailscan be varied without-(le- 'parture from the essentials of the invention as defined in the claims.
