SIGNAL SYSTEM.

SPECIFICATION forming part of Letters Patent a... 781,319, dated. January 31, 1905.

7 Application filed February 2, 1904. Serial No. 191,763.

To et whom it may concern.-

Be-it known that I, QLAUDE WHITE, a citi-. zenof the UnitedStates, residing at St. Louis,

State of Missouri, have invented certain new and useful Improvements in Signal Systems, of which the following is a specification containing a full, clear, and exact description, reference being had .to the accompanyingdrawings, forming a part hereof.

My invention relates to improved signal systems, my object being to provide an ef-' fective signal system whereby signals may be conveyed to trainmen on a running train View showing a signal system. embodying the principles of my invention. Fig. 2 1s a view in elevation, showing the signal-light directed into the cab of the locomotive within the plane of vision of the engineer and other trainmen. Fig. 3 is an enlarged detail of .the light and post. p

Referring to the drawings in detail, a series of posts 4 is arranged along the railway 5, and an electric wire 6 is strung on said posts, one end of'said wireterminating at the light 7 in the station 8 and the other end of said wire terminating at the light 9 in the station 10. A similar wire 11 leads from the light 12 in the station 8 to a similar light in the next station up the railway, and another similar wire 13 leads from the light 14 to a similar light in the next station down the railway. The I lights 15 are mounted upon the posts 4, arranged along the railway between the stations 8 and 10, each of said lights being connected to thewire 6, and similar lights 16 and 17 are connected to the wires 11' and 13, respectively. The generator 18 may belong to the streetcar or lighting plant of the town in which the station 8 is located, and said generator is conwires lead through this base.

nected to the switches 19 and 20, and said switches areconnected to the wires 6 and 11, respectively. The generator 21 may belong to the street-car or lighting plant of the town in which the station 10 is located, and said generator is connected to the switches 22 and 23, said switches being connected to the wires 6 and 13, respectively.

The-lights 1 5, 16, and 17 are constructed as shown in ,detail in Fig.3. Brackets 24 are attached to the posts 4, and semi-oval shells 25 are secured to the brackets. The lamp-base 26 is secured in the apex of the shell, and the The light-fixture 27 is attached to this base 26, a, reflector 28 is mounted in the shell 25, and the bulb 29 occupies a central position in front of the refiector, being connected to the fixture 27 through the reflector 28. A heavy concavo convex glass plate 30 is placed in the open end of the shell 25, and the edge 31 of the shell is turned in to hold the glass. The fixture thus constructed produces aconcentrated shaft of light 32, like a search-light, and the fixtures .are so mounted on the posts as to direct the shafts of light into the line of vision of the trainmen. The light-fixtures are preferably mounted on a level with the windows of the locomotive-cab, so that the shafts of light will cross the path of the locomotive and strike the eyes of the engineer and fireman and passthrough the car-windows and attract the at tention of the passengers, as well as of the trainmen.

' -In my signal system each station is independently connected with the next adjoining station in both directions, so that any piece of track between the two stations is protected by the signal system from both ends. The light may be red or white or of any desired color, and the power may be derived, as before suggested, from the local plants of the towns in which the stations are located, or, if

preferred, generating plants may be main-' tained exclusively for the purpose of operating my signal system. The lights in the stations are intended to show the operators when the signals are in operation. A code of flashlight signals may be arranged so that the opeach station, so that the lights may be illumierators may communicate any desired infornated from either end; substantially as specimation to the trainmen. l fied.

I claiml in testimony whereoflhave signed my name 5 In a signal system: a series of stations; a l to this specification in presence of two suh- 15 series of posts arranged along a railway bescribing witnesses.
