RAILWAY BLOCK-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 506,005, dated October 3, 1893.

I Applicationfiled January 17,1893. SerialNo. 458,729. (No model.)

To all whom it may concern:

Be it known that I, FRANK W. KLINE, acitizen of the United 'States, residing at North Germantown, in the county of Columbia and State of New York, have invented a new and useful Railway Block-Signal, of which the following is a specification.

This invention relates to railway block signals; and it has for its object to provide a combined light and alarm signal apparatus adapted to be used in connection with the ordinary block system, in which the roads are divided up into blocks or divisions of suitable lengths.

To this end the invention primarily con templates an automatically controlled block signal which is operated by the trains themselves, and which are so arranged in the blocks, as to aotivelyindicate at day or night to the engineer of the train, whether the block upon which he is entering is free from obstructions or not, and also to indicate whether another train is on the same block ahead of that train about entering thereon. In short, the apparatus is adapted to indicate all proper signals to the engineer.

With these and other objects in view which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts, hereinafter more fully described, illustrated and claimed.

In the accompanying drawingsz-Figure l is a front view of a block signal apparatus arranged at one side of the track, one rail of track showing. Fig. 2 is an enlarged detail in perspective of the signal pole and the signaling devices thereon. Fig. 3 is a central vertical longitudinal section view of the signal pole and the signal devices thereon. Fig. 4 is a plan view of the apparatus showing the fan board day signal in dotted lines. Fig. 5 is a detail plan View of the wire connections. Fig. 6 is a detail elevation of one of the spring lever catches.

Referring to the accompanying drawings, A represents a section of a track, alongside of which is arranged the signaling apparatus for one block, as herein described and set forth. At about the middle of each block and at one side of the track is arranged avertical signal pole B, of a height suitable to give the light signal at a proper distance, and said pole is provided at a point near the top thereof with the vertical slot 0, which receives the guide and supporting pin D, of the U-shaped lens frame E. The pin D, passes through both arms of the lens frame E and the slot in said pole, so as to provide for a vertical sliding movement of said lens frame. The lens frame E, embraces opposite sides of the pole B, and has thetwo arms thereof project in front of the track side of said pole, said arms carrying'in their extremities the colored lenses F, one of which is the usual danger color, so that when the light from the lamp is radiated therethrough, it will indicate danger or obstruction on the block. The extended arms of the lens frame E, are designed to work on opposite sides of the lamp G, which lamp is supported in a suitable socket H, on the rail side of said pole.

A lifting link I, is pivotally connected at its lower end to one end of the lens frame E and at its upper end to one end of the weighted lifting lever J The weighted lifting lever J, is pivotally mounted at or about its center on one side of the pole B, on the pivot rod T and normally lifts the lens frame E, above the lamp, so as to carry the lenses out of line with the light from the lamp, so that, normally, the light signal will not bedisplayed. When the lens frame is set to give a signal, the same is drawn downward by means of the setting wire K, connected at one end to the frame, passing over a suitably arranged guide pulley k, at the base of the pole and connected at its other end to the outer end of the signal setting lever L.

The setting lever L, is pivotally mounted near the track in the block Z, and is provided at its innerend with the upturned tread lug Z,-which lies inside of one of the rails of the track. Arranged over the tread log of the lever L, is the tread or press spring M, the slotted ends m, of which, move on the pins m, in the ties, and the central bow portions of which normally project a distance above the rail, so that the wheel of the locomotive will depress the same and the inner end of thelever L, so as to raise the other end and draw on the cord K, to draw down the lens frame in a position in a line with the lamp.

From the drawings it will be clearly seen that the pivot rod T, which carries or supports the weighted liftinglever J, is extended at the track side of the signal pole, and has attached to such extended end the fan signal board U. The fan signal board U, is painted the usual designating signal colors, so that when it is turned in a proper position, it signals danger from one side and a clear track from the other. As the lens frame E, is normally lifted by reason of the weighted lifting lever, out of alignment with the lamp, the fan signal board U, is disposed in a horizontal plane so as not to display any signal whatever, but when the lens frame is drawn down byreason of the connections just described, the fan signal board is simultaneously turned in a position to show its painted sides. The fan signal board is of course designed to give the proper day signals from the same operating mechanism which renders the movable lens frame useful as a'night signal, and in the description which follows it will be borne in mind that the day and night signals are simultaneously operated, so that one is available for day use and the other at night.

Now it will be readily seen. that a train ontering a block, and not seeing the signal displayed, passes on until it reaches the setting lever, at which point the lens frameand fan board are set to displaya signal in a manner just described, so that a succeeding train would be signaled, while the first train was still on the block as will be readily apparent. After the first train has left the block, the signal is automatically thrown oif in a manner to be presently described.

In order to insure the signals being observed, I employ in connection therewith, an alarm device which I will now describe. Secured to the rail side of the pole B, directly under the lamp G, is the bell N, below which is designed to work the reciprocating hammer arm 'n. The said hammer arm 91, moves through the guides 91', secured to the pole B,

and is pivotally connected at its lower end. to the upper member of a knuckle joint 0,

the lower member of which is loosely connected to the outer end of the horizontal operating lever 0. The horizontal operating lever 0, is pivotally mounted in the block 0', and is provided with an upturned tread lug 0 arranged inside of one of the rails, and over which is placed a tread or press spring M, such as previously described. To both sides of theknuckle joint, or to the joint pin thereof are attached the yokes P, to one of which is connected the cord 13, passing over a suitably arranged pulley p, and carrying a weight 19 which normally breaks the joint, while to the other of said yokesis connected a setting wire Q, one end of which is attached to the setting lever L. Normally, the weight 19 breaks the knuckle joint, so that a wheel depressing the lever 0, will not raise the hammer suificiently high to strike the bell. On

the other hand when the passing train has set the lever L, the knuckle joint is straightened out sufficiently, so that a train passing over the lever 0, will cause the alarm to be struck.

Just before passing ofi of a block, the end of which is indicated by the pole Z, and just before passing over the setting lover of the next block indicated in full lines, the train passes over a throw-off lever R, similar in construction to the lever L and also having a press spring M, over the rail end thereof. The outer end of the throw-off lever has attached thereto the wire r, passing over a suitablyarranged guide pulley r, and connected to the outer end of the setting leverL. When the track end of the throw-off lever is depressed and the outer end "correspondingly elevated, the Wire r, draws down the elevated end of the setting lever and causes the signals to resume their normal position so as to indicate that the block the train has left is safe.

In order to hold the levers L, and R, in their elevated and depressed positions, I employ the lever catches S. The lever catches S, comprise the opposite inwardly bent spring arms 3, arranged in the boxes 3. The inwardly bent spring arms 3, at a central point are in close proximity to each other, so that the levers in passing above and below such central point spread said spring arms apart, so as to allow the same to close over or under the levers, as the case may be, to hold the same steady in both of their positions.

Before a train leaves one block and reaches the throw-oh: lever thereof, it passes the signal pole of the next block which is shown in dotted lines in the drawings.

Now it is thought that the operation of the signaling apparatus will be apparent. When the lens frame or fan board day signal show no danger or when the alarm is not sounded by the train, the same runs by the signal post a suitable distance until it reaches thesetting lever. The wheels of the locomotive now depress the setting lever and set the signals for any approachingtrain, so as to protect such train and also to protect the first train should it stop on the block. If the first train has no cause to stop, and the next signal post shows no danger, it passes on and runs over the throw-off lever, which causes the signals of the last block to resume inactive positions.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
