To (ill whom it may concern.-

Be it known that I, EDWARD L. Onco'r'r, a citizen of theUnited States, and a resident of the borough of Manhattan, in the county, city, and State of New York, have invented certain new and useful Improvements in Electric Signalin Devices for Railways, of which the following is .a specification.

This invention relates to electric signaling systems for railways. g It seeks to provide an efiicient, economical, and reliable system and also one in which both track signals and cab'or train signals track signals are arranged in blocks along the track.

The invention also seeks to provide an eificient arrangement by means of which the train may be stopped when the block about -to be entered is dangerous or occupied by a preceding train; v

In the accompanying drawings forming part of this specification, and in which like numerals indicate corresponding parts in the several figures. Figure bodying the invention; view showing a modification; and Fig. 3 is a 1 is a' diagram emdiagrammatic representation of a rotary from'each other.

transformer, or motor dynamo, which may be used-in place of the stationary transformer shown in Figs; 1 and 2,

} Referring now to the drawin s and more particularly to Fig. 1, thetrac is divided into blocks of which the rails 1 and'2 belong to the first block, rails 1 and 3 belongto the second block, and rails 1 and '4 belong to the third block. Rails 2, 3, 4, etc. are insulated Rail 1 may, as shown, be

-, electrically continuous through the several blocks. 5 and 13 are two separate track contacts associated with the block to which the rails 1 and 3 belong, These track contacts 5 and 13 consist of suitable electric c0nalong the trackfor a immediately in ad which they belong.

considerable distance vance of the block to They arepreferablyformed of rails fixed to wire torail 3 and the road-bed." Track contact 5 is connected by wire 6 through resistance 7, or its equivalent, to rail 3 at the entering end of the block. At the opposite end of the block is transformer 8 whose primary coil 9 is connected by rail 1.

connected by wire 18 to wire 12 and is connected by wires 17 and 15 to track contact 13. Wires 17 and 15 include magnet 14 which controls the signal circuit as will be now described. The Wire 19 is connected at lamp 28 to wife 25. Wire is rail 1. Thus magnet 14 is connected in a controlling circuit which includes the secondary of transformer 8, and this magnet 14 block. This track signal may consist of any type of signal capable of giving a danger'and safety indication, as required, and this signal may be operated from any convement Fig. 2 IS a similar tricity located on drawings, this signal consists of two lamps. Lamp 24 lights up to show that the guarded train is occupying the block. Lamp '28 lights up to show that the guarded blockis safe, as for example when there is no train in the block. I

. track signal by wires 11 and 12 to Secondary coil 16 of transformer 8 is As shown in the accompanying drawings, the signal consists of the danger and safety lamps 24 and 28, and is operatedby the sig nal circuit which includes wire 19, armature 2O, wire 25, and rail 1.

In the preferred arrangement of. the systern, the generator for energizing the transformer and for furnishing the power to the is carried on the train. Any suitable type of generator may be employed.

30 is the generatoron the train. One side of this generator is connected by wires and 36 to a traveling contact37 carried. by the train and arranged to travel in electric connection with rail 1. The other side of the generator is connected by wires 34 and'33 to. a traveling contact 31 carried by the train and which is arranged to make electric connection with track contact 5. When the train reaches contact 5, the rail circuitfor ienergizing transformer 8 is completed as folows;

one end to wire 6 between track contact 5,

24 to wire 25, and front contact 26 is'connected by Wires 27 and 29 through safety,

connected to a source, but preferably from a source of electhe train. As shown 111 the is arranged to control the track signal, for the r section is dangerous, as for example when a I from generator 30, through wire 36, contact 37, rail 1, wires l2 and 11, primary 9 17, secondary coil 16 of transformer,

there is a preceding train device, such as the signal.

ofa transformer 8, wire 10, rail 3, resistance 7, Wire 6, track contact 5, traveling contact 31, and wires 33 and 34 back to generator 30. tion carried on the train completes the controlling circuit through magne 14 which is thereupon energized from the secondary coil of transformer 8. The controlling circuit thus completed may be traced as follows traveling contact 32 carried on the train, stationary contact 13, wire 15, magnet 14, wire wires 18 rail 1, traveling contact 37, wires 36 and 40, magnet 39, and wire 38 back to contact 32. At the same time, the signal circuit for the track signal will be completed from generator as followsfrom generator 30 through wire 36, contact 37, rail 1, wire 25, through either lam -24 or 28, armature 20, wires 19 and 6, track contact 5, contact 31, wires 33 and 34, back to generator. If there is no preceding train on rails 1 and 3, then magnet 14 will be energized so as to give a safety signal to the a proaching train-that is to say, lamp 28 will light up. If, however, on rails 1 and 3, then the primary of transformer 8, which is in the rail circuit, 'will be shunted by this preceding train and a danger signal' will be and 12,

given-that is to say, lamp 24' will light up in advance of the approaching train.

It will be seen that the rail circuit. which includes the primary of transformer 8 and the signal circuit which includes armature 20 are arranged in multiple, both deriving their current from generator 30. In order to suitably divide this' current between the two circuits, some resistance device, or equivalent resistance coil 7, is employed. In the bestembodiment of the complete inventlon, a signal or signals are carried on the train, and generally in the engineer's cab. These signals also indicate the condition of the track in the same way as does the track 51 and 63 indicate electric lamps which together constitute the train signal and which are arranged in a circr it controlled by magnet 39. Magnet 39 operates armatnre 43 providedwith a retractile spring 44. Back contact 51 of armature 43 is connected by wires 62 and 64 through danger lamp 63 to wire 53, which latter is connected by wires 54 and 35 to generator30. Front contact 46. of armature 43 is connected by wires 47, 50, and lilthrough lanip 51 to wire 53. Arnie-t ire 43 is connected by wires 45 and 34 to the opposite side of generator 30. It will be thus seen that when armature 43 is against front contact 46 aafety lamp 51 lights up, and that when armature, 43 is against ack contact 61 danger lamp flit-lights up. lifagnet 39 is included in a circuit on the which is normally closed, that is, before the train has reached track contacts 5 and 13.

At the same time, a circuit connec ma net 39, wire 38, traveling contact 32;

been stop 42, wires 41 and 34 to generator 30. Thus armature 43 will be normally held against front contact 46, and lamp 51 will be normally lighted. When traveling contact 32 meets track contact 13, the local circuit through magnet 39' is broken at 42, but magnet 39, being connected on one'side to travelin contact 32 and being connected on its ot ier side to traveling contact 37, will be connected in the controlling circuit which includes magnet 14 and secondary coil of transformer 8 so that if there is no preceding train on rails 1 and 3 magnet 39 will continue to be energized, but from secondary coil of trans former 8, thus continuing a safety signal in the cab from lamp 51. f, however, a preceding train is on rails 1 and 3, magnet 39 will receive no current from transformer 8 and armature 43 will shift to back contact 61 thereby ener izing danger lamp 63 on the train so as to ight up this lamp.

48 is a magnet carried on the train and connected on one side to Wire 47 and on the other side by wire 49 to wire 54 so that it is energized whenever lamp 51 is energized. This ma net 48 operates armature 55 provided wit the retract-ile spring 56 and connected by link to lever 59, which lever operates a valve 57 in a fluid pressure pi e 58. his fluid ressrre pipe 58 may be uti ized to work an a ditional signal, such as a whistle, or to supply the motive power for the car or train.

When the magnet 48 is energized, that is, when the track is safe for the advancing train, fluid pressure world be supplied through pi e 58 to operate the train. When, however, t e track is dangerous for the train, then magnet 48would be de-energized at the same 12-11116 that danger lamp 63 lights up and fluid pressure in pipe 58 world be cut off so as to stop the train. If fluid pressure pipe 58 is used to operate an additional signal, such as a whistle, then the whistle would be blown to indicate danger when magnet 48 is (la-energized.

In the diagram shown in Fig. 2, the arrangement is the same as that shown in Fig. 1 except with reference to some of the circuits on the train. This will be now described. In Fig. 1, magnet 48 is arranged in multiple with lamp 5] so that both are controlled by armature 43. In Fig. 2, magnet 48 is arranged in a separate circuit controlled by armature 66 which is operated by magnet In Fig. 2, wire 50 is connected at one end to front contact 46 and at its other end to lamp 51. Wire 47 is connected at one end to wire 49 and at its other end to one side of magnet 65. The other side of train this magnet is connected to one side of ma net 39, the opposite side of this magnet 39 being connected by wire 38 to contact 32.

. besimultaneously energized from generator 30 and will be simultaneoulsy denergized when the circuit through the magnets is broken at contacts 32 and 42. Moreover, it will be noted that magnet 48 will be energized through armature 66 simultaneously with the energizing of lamp 51 through armature 43.

Thus magnet 48 operates at the same time and for the same purpose in Fig. 2 as it does in Fig. 1; y

In Fig. 3 is shown a diagram of a rotary transformer, or motor dynamo, 8. This may be substituted for the stationary transformer 8 shown in Figs. 1 and 2, in which case wires 10, 11, 17 and 18 will be connected in the track circuit and in the controlling circuit in substantially the same way as shown in Figs. 1 and 2.

It is to be understood that'the various features of the invention may be modified and combined in different ways Without departing from the substance of the invention.
