. T @ZZ whom t may concern:

Be it known that I, CLAUDE WHITE, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and'useful Improvements in Signal Systems, of which the following is a specification containing afull, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

l My invention relates to signal systems, my object being to construct a signal system by means of which signals may be sent to and from the trainmen upon a running train between stations; and my improved signal system comprises a series of stations arranged along the railway, each station being independently connected by three electric wires with the next station, both up and down the track, lights of contrasting colors connected to said wires, said wires being normally deenergized, a live wire extended along the railway, and means of connecting the denergizedwires to the live Wire at any desired point, so as to send signals to or from the trainmen upon a running train between stations. I i

The further object of my invention is to provide a lamp which will showthree distinct colors or any combination that can be` made from three colors and introduce the lamp into my signal system.-

In the drawings, Figure 1 is a diagrammatical view showing my improved signalsystem with reference to two stations, the wires extending to the next stations up and down the track being broken away. Fig. 2 is a front elevation of a locomotive upon a railroad-track 'and showing signals. directed within the plane of vision of the engineer and other 44 at the station 15.

'31 may be any source of electric power in the town in which the station 15 is located, said generator being connected to the wire 30, ex-

tending down the track to the station 11, and said generator being connected with the live Wire 32, extending up the trackfrom'the station 15. At the station 11 the wires 29 and 30 are connected together and connected to. the switches 33, 34, 35, 36, 37, and 38 within` the station lil. At the station 15 the wires 30 and 32 are connected together and connected to the switches 39, .40, 41, 42, 43, and AtV the station l1 the wires 16, 17, and 18 are connected to the switches 33, 34, and 35, and the wires 5, 6, and 7 are connected to the switches 36, 37, and 38. At the station 15 the wires 5,6, and 7 are connected to the switches 39, 40, and 41, and the ywires 22, 23, and 24 are con nected to the switches 42, 43, and 44.

Thestations 11 and 15 represent two of a series of stations arranged along the railway 45. Posts 46 are arranged along one side of the railway 45, and posts 47 are arranged along the other side of the railway- 45. Upon each post is a lamp comprising the back wall 48, the top 49, the bottom 50, horizontal partitions 51 and 52,

- a glass front plate 53, the glass side plates 54 and 55, the red bulb 5 6 above the partition 51, the white bulb 57 between the partitions 51 and 52, and the green bulb 58 below the partition 52. All the parts of the lamp are opaque except the glass plates 5 3, 54, and 55, so that when the bulbs are illuminated the lamp will give off three distinct colors of light, asindicated by the'red, white, and green rays 59, 60, and 61 in Fig. 2. A switch 62 is Inounted upon each of the posts 46, and switch connections 63, 64, and 65 are located in the switch-box, one side of each of said connections being connected to the live wires 29, 30, and 32 and the other side of said connections being connected to the wires 5, 6, and 7, 16, 17, and 18, 22, 23, and 24, each of said wires being independently connected to the corresponding bulbs 56, 57, and 58 upon the posts 46, and the Wires 66, 67, and 68 connect the bulbs 56, 57, and 58 upon the posts 46 to corresponding bulbs upon the posts 47. All of the lamps are grounded or provided with suitable return-wires. The switch-boxes 62 are controlled by keys carried by the trainmen, so that the trainmen may stop at any point between the stations and by manipulating the switches 63, 64, and 65 send signals along the track and to the stations 11 and 15.

The operation of the signal down the track from the station 11 and up the track from the station 15 is the same as that already described.

A code of signals may be arranged by which any desired information may be communicated either to or from the trainmen.

1. Inra signal system, a series of stations arranged along the railway, each station being independently connected by three wires with the next station, both up and down the track; lights of contrasting colors connected to said Wires; said wires being normally denergized; a live wire extended along the railway and means of connecting the denergized Wires toA the live wire at any desired point, so as to send signals to or from the trainmen upon a running train between stations.

2. In a signal system, a series ol stations arranged along the railway, each station being independently connected by three wires with the next station, both up and down the track; lights of contrasting colors arranged along the railway and at the stations and connected to said wires; said wires being normally deenergized; a live wire extended along the railway; and means for connecting thedeenergized wires to the live wire at any desired point, so as to send signals from the stations to the trainmen upon a running train between the stations, or from the trainmen to the stations; substantially as speciied.

' 3. In a signal system, a series of stations; each stat-ion being paired with each adjacent station; three series of lights ot contrasting colors arranged between the stations; a live wire connecting the stations and switches arranged so that either series of lights may be illuminated from either end or at any desired point between thestations.

4. In a signal system, a series of lights and means of illuminating the lights; each light comprising three globes of contrasting colors; opaque partitions between the globes; opaque back, top and bottom; and glass front and sides, substantially as described.

In testimony whereof- I have signed my name to this specification in the presence of two subscribing witnesses.
