IMPROVEMENT BREAKAGE-SIGNALS FOR RAILWAY CARS.

Specication forming part of Letters Patent No. 122,386, dated January 2, 1872.

To all whom itmy concern: i

Beit known that I, SAMUEL JACKSON, of the city and county of Philadelphia, in the and useful Improvement in Breakage-Signals on Railroad Trains; and I do hereby declare scription thereof, which will enable others skilled in the art to which it appertains to make and use my improvement, reference bef ing had to the accompanying drawing, which Figure l, Sheetl, is a side view of a railroad train provided' with my improvement; Fig. 2, a perspective view of the apparatus when the iiexible connection between the cars of the signalltube, water-tube, and air-pipe; and Fig. 4, a side view of the yair-pipes, flex- The same parts are denoted by the same letters in all the figures.

A A inv the drawing represent the several sections of an open pipe or tube, which I prefer to make of iron, and which are attached in 'any convenient manner below the foot-board of the engine, the tender, and the ears.` rlhe several sections are connected by means of the flexible tubes Band the couplings C C. The flexible tubes, which I prefer to make of India rubber, are drawn over the ends D of the pipe sections. These ends may be made sertion into the tubes B, and annular grooves or recessesmay also be made at the base of each cone, into which grooves the ends of thel which 4are not only air-tight 4but may easily be These exible tubes or hose should belong and not to be detached from the pipeAby the ordinary oscillations or lateral movements of the train. The tube B at the'rear end of the train is closed air-tight by any suitable plug', E, as seen in Fig. .1, or the rear end of the pipe may itself be closed byv an elastic or expansible plug. The section of pipe A, which is attached under the locomotive, is turned upward so as to enter a vertical tube or box F. This tube, as well as the pipe, is open at top, and they have about the same height. The tube F should be kept iilled with water to within a short distance of the top. G is the signal tube, closed at top and open at bottom, and of such diameter as to slide freely within the water-tube F.

The tubes F and G should be placed on some part of the locomotive where the signaltube will be directly under the eye of the engineer. G may have a cap, Hag, light, or any device attached to it which will render its descent, hereinafter explained, as conspicuous as possible 5 or it vmay be connected by any suitable mechanism with a bell, whistle, 8vo., so as to operate the same when it beginsto descend.

lIn'the operation of these devices, when a car is coupled to the train thev plug Eis withdrawn and the iiexible tube at the rear of the train detached from the pipe A. The tubes B are then connected with the coupling, their outer ends drawn over the adjacent ends of pipe D D, and the coupling screwed u'p.

` When the train has been made up the rear orifice of the section of pipe A on the rear car should be closed with a iiexible tube and plug, as heretofore described, or in any other suitable way.

The train being coupled and ready to sta-rt, and the tube F filled with water to within a short distance of its top, the engineer inserts the signal-tube into it. The air within the signal-tube and` pipe A is compressed by the weight of the signal-tube and sustains'it in the elevated position shown in Figs. l and 3.

The breaking of an axle, the deviation of a car from` the track, or any accident which causes a displacement of the train or a part thereof from its proper position, will Withdraw one or more of the flexible tubes B from the pipe A and permit the air coniined in said pipe to escape, so that the signal-tube, being no longer supported by suoli compressed air, will instantly descend and thereby notify the engi` neer of the accident.

What I claim as my invention, and desire to secure by Letters Patent of the United States, 1s-

1. A signal apparatus, so constructed that the act of disconnecting the train shall operate Water-tube with the pipe A, constructed in the signal by permitting the escape. of the air sections, connected by flexible tubes..

confined therein, substantially as described. SAMUEL JACKSON.

2. The combination of the air-pipe A extending along the train, the Water-tube F, and Witnesses:

the signal-tube G. WM. R. WRIGHT,

3. The combination of the signal-tube and MILLARD F. VVALTON. (120)
