RAILWAY-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 715,183, dated December 2, 1902.

` Appiiaeon nea May 31,1962. sein No. 109,769. (Numan.)

To a/ZZ whom, t 11i/ty concern:

Be it known that I, WILLIAM HENRY WAL- TON, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Railway-Signals, of which the following is a specification.

My invention is particularly designed for electric railways or other railways operating 1o single cars; but it is also capable of application to railways having trains of cars. It is also especially intended and .is described hereinafter as applied to a tunnel-road or to the tunnel-section of such a road, but may be also used on other parts of a railway system.

The object of the invention is to enable a car to block the section or portion of track immediately behind it automatically and without the use of mechanical signal-'operating 2o devices.

To this end my invention consists in arranging iixed signal-lamps in such relation to the track or tracks as to be obscured or hidden by the car itself from an immediately succeeding car. Preferably the form of signal adopted has screens so arranged as to permit the light to be observable only from the direction of approach Of trains and to hide the lightin the other direction, so that where double tracks are used the light of one track will not confuse the motorman or engineer whose vehicle is on the adjacent track.

In the accompanying drawings, Figure lis y a plan view of a double-track tunnel-road to which my invention is applied. Fig. 2 is a longitudinal sectional elevation thereof. Fig. 3 is a transverse sectional elevation of one track of such road to a larger scale. Fig. 4 is a longitudinal sectional elevation, to the 4: same scale as Fig. 3, of a single signal and adjacent devices. y

The tunnel-walls are represented at l and the tracks at 2. Located between the rails of the track are fixed or immovable signallamps 3, which are maintained constantly lighted and'have a reector 4 so arranged in relation thereto as to throw their light only toward the oncoming cars of the track in which such signal is placed. The lamps may be electric, as shown, and lighted from any vment of the cars.

convenient source of electricity or may be oil orgas lamps, as is most convenient. As shown in Figs. 3 and 4, the reflector or shield 4 affords a supporting and containing case or box for the lamp and is fastened upon the crosstie of the track or separate foundations. The distance betweenthe lights will depend On local conditions and on the speed of move- I have shown in Fig. l an arrangement ot' three of these lights on one track and two on an adjacent track at somewhat more than Aa cars length apart. This is, however, for purpose of illustration only, as the-lights would preferablybe arranged at considerably greater distances apart. In operating the rules may require one or more of these lights to appear between the car 5 and the next car 6 in front thereof. It will be noticed that at the right hand of Fig. 1 the car 6 is immediately over one of the signals and will hide it entirely from the car 5, so that the motorman on the latter will see only a single signal, and it is believed to be the best condition OE operation to have at least one signallight showing between the cars.

In addition to the arrangement of a signal between the rails the signal 4a may be arranged alongside of the track, either adjacent to the several signals 4 or interspaced therewith. The signals 4a, if serai-ranged, will, as shown at the right hand of Fig. 1, be so close to the car as to be hidden from a succeeding car when the car 6 is passing. The lights 4a are, as will be noticed, arranged at the lefthand side of the track, which in case of a double-track road, such as shown in Fig. l, will bring all ot' them between the-tracks. For daylight use the inner surface of the reector 4 may be under some conditions and if painted an appropriate color-red, for instance-serve as a suiicient signal device should the lamps 3 be extinguished.

It will be observed that the form of signal device herein described is not dependent for the proper fulfilment of its function upon 95 the operation of any movable mechanical devices and is simple and always in order; also, that either of the arrangement-s herein shown and described or any equivalent thereof for placing the signals in such relation to the rco track that they Will be obscuredv by a passing car from the following car is intended to be covered by the broader statements of claims hereinafter made.

asucceedingcarortrain and having deflectors arranged to `obscure the sig-nal devices in one direction. Y

3. In a railway-signal, in combination with a track, a xed signal device or devices arranged between the rails thereof and projecting into View of an approaching car but arranged to be hidden by a car or train from a succeeding car or train on such track.
