EIJECTRIC SIGNALING- DEVICE.
Specification of Letters Patent.
Application filed September 1,1906. Serial NO- $3,004.
citizen of the United States, and a resident ofthe borough 'of Manhattan, in the county, city, and State of New -York, have invented certain new and useful Improvements in Electric Signaling Devices for Railways, of which the following is a specification.
This invention relates to improvements in electric signaling devices or systems for railways. It' seeks to provide an efficient, reliable and economical arrangement and whereby track signals may be operated in a block system. The signal, or signals, for each block is or are controlled by a track circuit energized by a transformer, and the transformer is energized by a suitable generator carried on a passing train and arranged to be connected with the supply circuit Which energizes the transformer when the train is about to enter a block. Each train thus carries a generator, and a track circuit of a block would notv be energized until a train was about to enter that block. The
transformer may be in any convenient form. In the accompanying drawings forming part of this specification, and in which like numerals designate corresponding parts in Figure 1 represents a diagram of an improved signaling device or system having a singlesafety and .danger signal arranged at the side of the track and embodying the invention; and Fig. 2 represents a diagram of the improved signaling device or system, and in some respects similar to Fig. 1-, but differing principally from Fig. 1 in the fact that it has a plurality of track signals. 4
Referring now to the specific arrangements shown in the drawings, 1 is one of the rails of the track which may be, and preferably is, as shown, electrically continuous.
The opposite rail of the track is divided into insulated sections 2, 3, 4, etc. 5 is a secondary coil of an ordinary stationary transformer 6. One end of this coil is connected by wire 7 to the end of the rail section 3. The other nd of this coil is connected by wires 8 and 9to the rail 1. Thus the transformer 6 is connected to the rails near the exit end ofthe block. 10 is a magnet connected by wires'll and 12 to the rails 3 and 1, respectivel Thus the magnet 10 is connected in the track 'rails 1 andB and the secondary coil of the transformer. 13 is the primary coil of the transformer,
one end of which is connected by wire 14 to Patented June 4,1907.

wire 9. and the other end of which is connected by Wire 15 to the track contact 41. 1 The track contact 41 may be constructed and arranged for some the entering end of the block and preferably consists of a rail fixed on the road-bed. The magnet 10 is arranged to control the track signal.- This-signal may be of any-convenient type and may be operated by any con-- venient source of power. I
In the preferred arrangement and as shown in the drawings, the, track signal. is operated by the current of the supply circuit of which the wire 15 is a part. The track signal, as shown in Fig. 1 of the drawings, consists of two electric lamps which would be colored red to indicate danger, and the latter of which would be white to indicate safety. These two lamps toether constitute a signal capable of giving anger and safety indications and they are arranged, as shown in the drawings, to be operated by a current in the supply circuit. In this arrangement, armature 18 of magnet 10 is connected by wire 19 to wire 15. Back contact 20 is connected by wires 22 and 23 to Wire 24, and front contact 25 is connected by Wires 26 and 27 to contact 24. Wires 22 and 2& include the lamp 16, and wires 26 and 27 include the lamp 17. Wire 24 is connected to rail' 1. Spring 21 normally holds armature 18 on its be seen that the lamps 16 or 17, is connected in a shunt to the supply circuit. When magnet 10 is energized, lamp 17 will be in the shunt, and when the magnet is deenergized lamp 16 will be in this shunt. Z
28 is a generator located on the train. v" One pole of the generator is connected by wires 31 and 34 to a shoe, brush, or other convenient form of traveling contact 35 carried by the train. The other poleof the generator is '16 and 17, the former of back contact 20. Thus it willarmature 18 and one" of the in any suitable way. It extends I distance immediatelyin advance of connected by wires 36 and 33 to a traveling contact 32 carried by the train andarrange to make connection with the rail 1. The contact 35 is arranged to makec'onnection with track contact 41.
circuit which includes I 30 is a signal, and preferably a lamp, o
nected to wiresfil and 36 in circuit with the generator. This lamp, or signal 30 is preferably located in the'engine cab and indicates to the engineer whether or not the genorator 28 is in working order. The contact 32 makes continuous electric connection with'rail 1,
In the operation of the system, when the train reaches the track contact 41, contact 35 makes electric connection therewith. This contact 41 extends for some distance along the track immediately in advance of the block guarded by the signal lamps 16 and 17. When contacts 35 and 41 make connection, the supply circuit is closed. This circuit is as followsfrom generator 28, wires 31 and 34, contacts 35 and 41, Wire 15, pri mary coil'13 of transformer 63, wires 14 and 9, rail 1, contact 32 and wires 33 and. 36, back to generator 28. This circuit energizes sec ondary coil of-transformer- 6 and energizes the track circuit through magnet 10. If
-. there is no preceding train in the block guarded by signal lamps 16 and 17 that is, on rails 1 and 3, magnet will be energized. so that armature 18 will move to front contact 25. This will close the shunt which includes safety lamp 17 and cause this lamp to light up and show safety to the engineer on the train If, however, there is a preceding train in the block,'that is on rails 1 and 3,
track magnet 10 will be shunted by the train so that armature 18 will remain on back contact 20. This closes the shunt which included danger lamp 16. This will cause lamp 1.6 to light up and show danger to the engineer. If neither of the lamps 16 or 17 light up, this would indicate a break or other failure in the supply circuit and would be taken to mean a danger indication to the train about to enter the block guarded by the signal.
In Fig. 2 there are a plurality of track signals 16 and 17. As. there shown, the three danger signal lamps 16 are arranged in multiple and connected. 011 one side to back contact 20 and on the other side to wire 24.
The three safety signal lamps 17 are arranged in multiple and connected on one side to the front contact and on the other side .to the wire 24. Thus when the su ply circuit is energized and magnet 10 is a so energized all the safety lamps 17 will light up to. show safety. If, however, the supply .circuit is energized and magnet 10 is not energizelrl, all the danger lamps 16 will light up.
11 1' 2, lamp in Fig. 1'. This magnet42 operates an armature 37 connected. by link 39 to lever '38. Lever 38 operates a valve 36 in a fluid 7 pipe 40 which may operate a whistle, or other suitable alarm, o'r control the air brakes. Various other changes may be" made beside those herein indicated without departwv ing'from the invention.
