RAILWAY TELL-TALE.

SPECIFICATION formingpart of Letters Patent No. 266,802, dated October 31, 1882.

Application tiled December 22, 188i,

To all whom it may concern Be it known that I, MATTHIAS N. FORNEY, of New York, county of New York, State of New York, have invented or discovered a new and usefulImprovementin Railway Tell-Tales and I do hereby declare the following to be a full, clear concise, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which-like letters indicating like parts-- Figure 1 shows in cross-section a railwaytrack, the outline of a cab, home and distant signals in elevation, in connection with the appliances to which the present application more especially appertains and Fig. 2 is a diagrammatic view of a track-crossing illustrative of one manner of arranging the signals with reference to using the presentinvention therein.

In United States patent granted to me December 6, 1881, No. 250,517, I showed and described certain tell-tale and alarm devices adapted to be used as an attachment to signaling apparatus; but the same being held to be aseparate invention 1 made no claim therefor therein, but reserved the right to claim them in a separate patent. The present application is designed for this purpose, and while I have shown in part the same signaling apparatus as in said patent I have done so only to illustrate one out of many practicable ways in which the signals themselves may be actuated, and hence, as regards the tell-tale and alarm herein described, I do not limit myself to the use, in connection therewith, of any particular means of actuating the signals. Such work may be done by an ordinary hand-lever or other like known device, either with or without the addition thereto of any of the known forms or construction of locking or interlocking appliances. Hence I do not deem it necessary in this application to describe any particular means of actuating the signals, except that the upright home-signal shaft B may receive the proper motions by means of a worm-gear, B, or otherwise, at pleasure, and a rope, cord, or equivalent connection, b,1nay extend to the distant-signal shaft, so that by a single motion the home and distant signals shall both be operated at the same time or successively by separate motions, as may be preferred.

(N0 model.)

In the accompanying drawings I have represented a home danger-signal as consisting of a double semaphore-arm, A, attached to a vertical signal-shaft, B, which may be operated in any suitable way. The safety-signal may consist of a vertical board or plate, E (shown in dotted lines,) and placed at right angles to the danger-signal A Consequently when at a crossing the latter is at right angles to one line oftrack and in dieates danger or stop to an engineer approaching thereon, the safety or line-clear signal isdisplayed to the other. On top of the cab or in any suitable position socketed castings a are placed. These carry what may be called safety-staffs 1). Holes are made through the sides of the socket and through the staff, and the two are secured together by a string or wire and seal, 0.

On the ends of the semaphore-arm A arms R R are attached. These are so arranged that in case an engine should pass the signal while displaying danger to the engineer one ofthe arms It It would break off the statt' b, and as the engineer could notplace and reseal another the breaking ofa staff would be a tell-tale which would show that he had passed a danger-signal. I also provide for giving an alarm to an engineer in case he runs past adanger-signal; and while such alarm may also be applied to a home signal it is of most value as applied to a distant signal, and I have so represented it, H beingthe signal in a danger position, and adapted to be operated in any suitable way by a rotary shaft, G. N is a stout arm attached to the shaft, so as to stand out toward the track when H is at danger. It has an iron weight or anvil at its outer end, and placed in a proper position to strike a torpedo or detonator attached to the side of the engine-cab by a suitable support, P. Then in casesayin a fog-the engineer fails to observe the signal at danger the explosion of the detonator will at once call his attention to the fact.

Among other convenient arrangements of such apparatus as applied to a track-crossing, I have illustrated one in Fig. 2. The home signal may be arranged at a and the distant signals at a a, the signals being here set so as to block track No.1 and give safety to track The signals may be duplicated for the other tracks. The form of the signal is not essential. A single board A may be employed for line-signals, and it maybe arranged to rise and fall instead of turn bya rotary motion, and it made long enough its extended end will be the mechanical equivalent of the arm R for the purposes in view. v

No claim is made herein to the alarm N P, and the right to claim the same in a separate application is hereby reserved 5 nor do Iclaim 7 herein a frangible signal attached to a signalpost and adapted to be engaged by the train, as described in English Patent No. 2,520 of 1856, which construction is open to the objection that road-signals should be kept unbroken, so as to be in condition for use with any and every train.

I claim herein as my inventiontially as described.

In testimony whereof I have hereunto set my hand.

MATIEIIAS. N. FORNEY.
