SIGNALING APPARATUS FOR RAILWAYS.

Specification of Letters Patent.

Patented June 5, 1917.

Application filed J 1.113 11, 1914. Serial No. 850,383.

caster, in the Kingdom of England, have invented certain new and useful lmprove ments in Signaling Apparatus on Railways, of which the following is a specification.

This invention has for its object a signaling device, automatic to a great extent, whereby whenever the last carriage in a train passes a given point, a fog signal is placed on the line, and remains until the signalman at the end of the block releases it by a wire or other connection.

It. is best described by aid of the accoinpanying drawings, in which Figure 1 is a longitudinal elevation of line and last carriage;

Fig. 2, end view of same; and

Figs. 3 and 4 side view of table for the detonator and its support respectively.

In these, A is the brake van of the train to which is fixed a curved or inclined spring controlled bar with a roller (l at the end. When not in use, it is placed up against the back of the carriage as shown in dotted lines at Gr. By the side of the rail, I place a fog signaling device C, and on the other side of the rail 1 place an oscillating rail D. oscillating on pivot E. This oscillating rail is weighted or provided with a spring, not shown, whereby normally it lies against a stop soas to present a gradual incline, as shown. At the fulcrum E, the roller on the last carriage will run over it without touching it, but beyond the fulcrum the roller coming against the incline depresses it. As the roller G may vary in height with the weight in the guards van, 1 may arrange any convenient regulating device which the guard can regulate before starting, such as movable bearings for the pin 1, on which the bar B is hung, that will bring the pulley to the exact height required but in the preferred form the bar is provided with a spiral or other spring so that it will have a certain amount of give or resilience. In the drawing an arrangement for this purpose is shown in which the bar B is formed in two parts pivoted together at R, and provided with a spring S, which holds it down to its normal position. The roller rolling up the incline at D causes the other end of the sloping lever bar to rise, and allow a trigger or sliding piece K attached to the fog signal laying device L to fly forward through a hole in the rail, and come into the space which the lever occupied before, so that when the rollerjeaves the lever and the latter descends it rests on the trigger or sliding piece. As the signaling device sliding piece darts forward it lays a fog signal M attached to it on the line the fog signaling device slides on the bar P screwed into the web of the rail as shown, and the device itself is pressed forward on bar 1? by the spring Q. The fog signal remains on the line until the train arrives at the next signal station, when the signal man by a wire or electrical or other connection N pulls back the trigger and fo signal of the fog signaling device, and tie weighted lever again falls down, waiting for the last carriage of the next train to set it again at danger. a train explodes the fog signal, the guard stops his train, and puts another fog signal in position in place of the one which has been exploded, though if desired the machine can be arranged so that every time the. signal is exploded another fog signal is immediately put into position, and the original fog signal discarded. This can be done by most of'the. fog signal operating devices already known. The train now stops until the Signalman reports the line clear, and sets the fog signaling apparatus again into operative position. The arrangement stands above the rail about the same height as a live rail, thereby clearing points and cross rails on the off side.

l declare that what I claim is:

i; In an automatic fog signaling device for railways the combination of a long rocking lever or pivoted rail weighted at the back end, a spring propelled fog signal laying device. an abutment on this fog signal Y laying device which normally comes in contact with the side of the pivoted rail hefore the fog signal comes to the rail, but when the pivoted rail is out of normal position is capable of coming forward into the position formerly occupied by the rail, and thus allowing the fog signal and its carrier plate to rest on the rail.

2. A fog signaling device consisting of an oscillating rail actuated from the rear end of the train. a mechanism carrying the fog signal. and attached to the signaling svstein of the railway. a spring in the mechanism. a war propelled by the. spring normally resting against the pivoted rail except when actuated from the mechanism in the train, the Force of the spring tending to cause it to slide in the position previously blocked by the pivoted rail whenever the pivoted rail is oscillated.

3. The improvement in signaling devices, which consists in an arm carried by the last vehicle of the train, a roller carried on said arm, a pivoted rail close to the main rail and weighted so as normally to come in contact with the roller when the train traverses the line alongside a fog signaling device placed outside the rails and connected with the ordinary signaling system, and connections between the pivoted rail and the fog signal device whereby whenever the pivoted rail is depressed a fog signal is placed on the main line.

i. The improvement in signaling devices consisting in a pivoted arm fixed to the rear end of the train and adjustable to allow variations in height in the last vehicle, in combination with a fog signaling device placed outside the rails and connected with the ordinary signaling system, and devices between the pivoted arm and the fog signaling device whereby the fog signaling de vice may be operated by said arm.

The improvement in fog signaling devices, which consists in a jointed lever pivoted at the top and capable of adjustment vertically and attached to the last end of the train, a roller at the top end of this lever and a spring giving the roller a considerable play in height above ground, a pivoted rail against which the roller normally comes in contact when the train passes, and a fog signaling device actuated by this rail.

6. The improvement in fog signaling devices, which consi ts in a pivoted rail close to the main rail, a device on the last end of the train capable of coming in contact with the pivoted rail when the latter is in normal position, and means whereby the movement of the pivoted ail puts a fog signal on the line, and holds it there until the signal man at the distant station removes it, or it is removed by hand.

7. In a fog signal laying device, an operating arm attached to the rear of the train, a pivoted rail in such position as to come in contact with the arm device when in I10rmal position, a fog signaling device normally kept from laying its signal on the line, but when the pivoted rail is actuated capable of sliding forward and inserting the signal on the rail, and a wire connecting the fog signal laying device with the distant signaling station.

8. In a fog signal laying device, the combination of an actuating mechanism on the rear end of the train, a pivoted rail in position to be struck and pressed down by said actuating mechanism when a train passes on the adjacent line of rails, a spring propelled slide normally held back by the pivoted lever, and a fo signal plate carried by pins in sockets in said slide, which slide when the pivoted lever is moved is free to spring forward, lock the pivoted lever and hold its signal 011 the line.

In witness whereofll have hereuntosigned my name this 30 day of June, 1914, in the presence of two subscribing witnesses.
