AUTOMATIC .RAILWAYTSIGNAL i 'A SPECFIQATION forming part of Letters Patent No. 497,5*30, dated May 16, 1893.' Appuntamenti@ 7,1892. semina/tasses. (Nomoaem' To all whom it may concern:

Be it knownthatl, CARLO BoRGHEsE, as'ubof Italy, residing at Turin, Italy,have `invented certain new and useful Improvements in Automatic Railway- Signals, of which the following is aspecilication.

This invention relates to the class of railway signaling devices designed to operate a train to warn, the engineer when a particular point is reached by the train. The signal produced by the present invention may be Visual or acoustic, but the latter is preferred. The signal may be employed in conjunction with, or as a substitute for the ordinary signals, and it may be emoroperate the conti'nucns brakes on a 'passing train.l

The invention comprises as its essential features two devices, one of which is placed on the track and the other carriedV by the 'moving train. The device placed on they track is in the nature of ,an obstacle, which may be either fixed in a permanent manner at some particular poi-nt on the track, or be adapted to be tixed hurriedly in a temporary manner to a rail, a `lleeper, or some .ther convenient part of the track. l The derice carried by the train, and perhaps most convenienty by `the locomotive drawingthe with means sleeper, or

4ate' the corresponding train. is designed to produce the signal by its en counter withthe obstacle on the track when stacle secured in place on the track may have various forms to -suit the circumstances so long as it isadapted to encounter and actudevice on the train. Itmay,-as stated, be portable, and vprovided for quickly fixing it to a rail or be set in place-in a permanent manner. lnthe latter case, it may be pro.-

;vided with,or combined with means for .op-

a distance, as in the case. of

erating it from acoustic signaling devices.

other visible or The device carried by the train may be iixed on the locomotive, forexample, at any point where it willv encounter the obstacle on the track. The signals'voperated by the device may be of varied kinds, optical, acoustic, &c.; itwill serve to employ anacoustic signal loud enough to ,be easily heard -by the engineer and trainmen. lThis signal may be a whistle,

The obvice to a block signal systemjis the obstacle or device spectively,

an electric bell, a steam or compressed air signal, &c. ln ordinary cases where the device is mounted on the locomotive, it will be conn venient to employ a steam whistle as a signal, 5 5v but it is preferable to employ another than the regular whistle of the locomotive.

In the accompanying drawings an embodiment of the'invention is illustrated, Figure.

tially of a cock or valve l), and a pendent 8o signal operating armor lever E, which is secured to and controls the oscillating plug of the cockand swings in a vertical plane-parallel with the track. The lower end `ot the arm E, is furnished with cushions e, e, of rub- Aber or the like to ameliorate the shock when the arm encounters the obstacle A.1 fixed' box, d, ofthe cock D, has two opriesitely arranged ports, in communication, re

through pipes steamboiler or compressed air reservoir on the'one hand, and with a Whistle,or otheranalogous signal, on ythe other hand, the cock D cutting oit the communication, normally," between said boiler h, of the cock l), is not pierced as usual, but has a circumferential groove, t', which extends nearly around the plug with one of the pipes (G inI Fig. 2) at all times, and whenever the arm E, is swung toroo ward either side of the perpendicular alittle' way, one orthe other extremity ofthe groovefixed on the track. l7o

On the upright l 'F and G, with a 9od and whistle. `The plug and is inconnection j 'i will communicate with the other pipe (F in Fig. 2). When the cushion e on the end of the arm E encounters the obstacle A,when passing, in which ever direction the train may be moving, the arm will be Yswung to one side and the alarnrsounded, and the alarm will continue to sound while the arm is displaced, thus warning the personnel of the train.' The arm E, Or the stem of the cock-plug, may have a cord or arm attached to it so that the engineer Or trainman can, if necessary, return the lever to its normal positiorandthe trainman may ascertain by this arm or device whether the arm E, is displaced in case the signal does not sound. These parts are not shown in the drawings as they are not indispensable and may be supplied by any good workman if they are needed.

I have shown one of the many ways in which the displacement of the arm E may be made tO sound an acoustic signalhand I do not deem it necessary toshow Otherways; it

fwill suffice' to say thatI the arm E, or some equivalent device, may be arranged to close a circuit through an ordinaryelectric bell. This could be effected by any o ne with'solne knowledge of electricity. 4 l

Fig. l, as I have said, showsan obstacle A adapted to be attachcdto the track rail at any point, and in a temporary manner;` and in Iig.` 3 I have shown how the obstacle may be secured in place in a permanent manner and b'e set to operate, or so aste be inoperative or inert, from a distant point. In this figure; a base-piece, M, embraces the foot of the rail and is secured tothe web of the rail by a bolt andthe obstacle A is hinged or pivoted to the base-piece at m, so thatit may belet down to the position seen in dotted lines, when its crown will not be in position to encounter the arm E On a passing-train. Onthe ObstacleA is an arm Z, to which is coupled an operating rod, n, which may extend to a considerable distance from the point where the obstacle is placed n the track. This type of the device is best suited for fixed installations, and is well adapted for use with disk or semaphore signals of the usual kind. In such a case the saine roth/n, may set the semaphore and the obstacle A,and the engineer will then receive an acoustic signal at the same time that the semaphore is displayed. It will only require ordinary skill and judgment to furnish themechanical details to adapt the'signal to dierent situations and-different roads.

It will be understood that my device as herein shown may be employed to set'the brakes 0f a passing train,'and particularly the Ordinary continuous compressed air and vacuum brakes. In this case' it will only be necessary to suppose the pipes F and G to represent the train-pipe, and the valve D to represent the ordinary train-valve or an analogous valve. The setting of the brakes will be a signal to the engineer and the trainmemalthough not, in the Ordinary senso, either auy acoustic or visible signal.

My improvements are adapted to any system of signal service on railways, either the block system or other systems, and as well to double track, as to single track roads. For example, as seen in Fig. 4, P and Q are two successive stations; p and q are the two signaling posts nearest these stations on the main line. Iam able to establish that when the station P should send a train toward station Q, it warns it and at the same time warns the post q to set its obstacle so as to arrest; the station Q, responding, notifies the post 1J to ope-n the line to its tower. It will thus be seenthat the line will only be Open when the two stations are in accord. It' each post closes the line after the passage of the train until further orders, each train remains blocked and all danger is avoided. y

Having thus described my invention, I

claim- 1.-- In a railway signal, the combination with a movable obstacle on the track, of the signaloperatiug arm E, carried by the locomotive or car, said lever having a yielding cushion, e, at

the point where it impinges upon the-'obstacle4 set on the track, substantially as set forth.

' 2. In a railway signal, the combination with la movable obstacle on the trackliaving an arched Or rounded crown, of the signal-operating arm E, carried by the locomotive or car, said lever having a yielding cushion e, with a. convex or rounded surface at the'point where it impinges upon the obstacle set on the track, substantially as set forth.
