.T all whom it may concern: 7

Be itknown that I, CHARLES CHEVAILLER, acitizen of the Republic of France, residing at l Rutland street, Regent, London, N. W., England, have invented a new and" useful. Device for Repeating on the Engine the Signals Given onthe Line, of which the fol lowing is a specification.

This invention relates to a device for repeating on the engine the'signals givenon the line. The signals are repeatedin' front of the engineer and of the stokerwho thus are immediately informed of the position occupied by the semaphore, the round'disk or the square disk, Whatever may be the weather, however badly the disk may be lighted, and forwhatever reason the signal 1 itself could notbeseen by the engineer.

' the signals.

This device has the advantage that it does not require any alteration in the lining or any transformation of the signals. The apparatus does not comprise a signal whistle which is a further advantage, since with an ordinary whistle the engineer relies too much on it and consequently neglects to watch the signals.

The device consists of two windows, a white one and a red one mounted on the windscreen of the engine. The windows are uncovered according to the position of If the line is blocked thered window is uncovered and the white is covered and inversely if the line is clear.

' The device for obturatingthe windows is controlled 'by compressed air sent out by rubber balls which are compressed by rods under the engine. This lever is-operated by a trip devicesituated betweenthe, rails and arranged at least 200 meters inrear of the signal from which it is operated itself.

A-lantern is mounted on "the line to indicate the 1 place where "the" apparatus is mounted so that, if the-signals are not visible the engine driver knows where they are.

In the accompanying drawings-the inven tionis shown by' way of example Figure 1 is a perspective view of a line with trip devices for repeating the signals on the engine. I v

Fig. 2 is a cross section of Fig. 1 the trip device being in the'positioii which it assumes'when the line is free orclear, Fig. 3 is a similar view which shows the device in the position which it' assumes when the line is blocked.

' Fig. 4 is a section on line 4:4 of Fig. 1. Fig. 5 is a front view of the wind screen with the red and white windows.

Fig. 6 shows the apparatus operating one of the obturators. Between the rails 1', 2 a trip device 3 is arranged adapted to pivot around an axle i. This trip device 3 is liftedbymeans of two connecting rods 5, 6. The connecting rod 6 is fixed on a shaft 7 which is mounted in bearings and is operated by the same apparatus which operates the signal to be repeated. On this shaft a lever 8 is fixed which has a counterweight 9 maintaining the lever in determined positions. This trip device 3 is preferably situated at the right of the line and it is provided alone if only the signals of the semaphore are to be repeated, but if also the signals of the round or square disk are to be repeated, which indicate slacken speed or stop respectively, two trip devices are arranged, one at the rightand the other at the left of the line. The second device is of similar construction to the first one and it further has an abutment 10, articulated at an axle 11 adapted to be maintained in lifted position by two of the lever 16 pivotally mounted on an axle 17 which" is fixed in a support 18 under the engine. The lever 16 is preferably provided with inclined surfaces 14,15 at the end, the incline corresponding'with the slope. of the abutments 3 and 10 to serve for softening or decreasing the shock when the lever comes in contact with the trip devices. The ends of the lever 16 carry rods 19, 19 with large heads 20. Above the heads 20 rubber balls 21 are mounted which are connected'by hose or conduits22 with the obturating devices for the white window 23 and red Window 24.

The rods 19, 19 (see Fig. 6) are located in tubular sliding pieces or guide tubes 25 in which saidrods can move, the movement of the rods being braked by means of blade springs 26 which bear against the inner wall of said tube 25. The blade springs prevent the accidental displacement of the rod.

The device for showing the signals in the cab is shown in Fig. 5 and comprises a lamp 27 located in a box 28 provided with a white window 23 and a red window 24. Arranged to slide between the lamp burner and the windows is a door or obturator 30 large enough to cover either of the windows while uncovering the other. Atthe lower end of the door are fixed impact blocks 32 for moving the door. Fixed to the box 28 are cylinders 3 3 with which the hose connections 22 are in communication and these cylinders are provided with plungers 31- which are operated by the air which is compressed by the action of the rods 19, 19 on their corresponding balls 21, (see Figs. 2 and'G) and are thus caused to strike against the blocks 32, driving the door 30 from its position closing one window to the opposite end closing the other window.

When the semaphore is operated, the lever 8 is actuated upon at the same time by means of a device similar to the tongue of a switch whereby the shaft 7 is rotated and consequently the connecting rod 6, fixed on said shaft is actuated. In moving, the connecting rod 6 assumes an almost vertical position and draws along the connecting rod 5 whereby the trip device is lifted. If now an engine which is fitted with the device hereinbefore described moves over the trip device,the inclined surface 14: which is in its lower position, strikes against the trip device 3 which is lifted, so that the lever 16 swings around the axle 17 and lifts the rod 19, the head 20 of which compresses the rubber ball 21. The air forced out of the rubber ball operates the obturator which uncovers the red window 24 and covers the white window 23. The engine driver can thus see at once that the line is blocked and has time enough to observe the semaphore before the engine arrives at the signal so that thespeed of the engine can be reduced and if the line is still blocked when the engine arrives at the round disk the inclined surface will still be lifted and consequently the red window will be still uncovered. The engine can slowly continue until it arrives at the square disk where it will stop. If, however, the square disk is in the open position the trip device 3 of this disk is lowered and the trip device 10 :lifted so that the in clined surface 15, will come in contact with. the trip 10 so that the lever 16 swings and the obturator is operated so that it covers the red window and uncovers the white window, the line being free the engine drivercan continue atfull speed.
