Specification of Letters Patent.

Patented July 17, 1906.

Application filed November 15,1905. Serial No. 287,534.

To all whom it may concern.-

Be it known that l, CARuELo DEL CAMPO,

a' citizen of Italy, residing in New York, in

- bv which train wrecks willibe' avoided, of

which the following is a specification.

The apparatus 18 illustrated in the accompanying drawings, in which Figure 1 a side view of the entire apparatus.

A B is a wooden board on which the apparatus is mounted. Said board is pierced by ahole on each of the four corners and screws on the side of the tender of the locomotive. The iron l'ever a revolves on stud b, which permits it to oscillate in either direction.

The upper end 0 of said lever has a shape of a disk, and the lower end has a slot on which is attached apiece of leather (1, held last by two screws. l

The sector 6, fastened to the board by screws and nuts at ff, acts as aguide to the lever. hen the same changes its perpendicular position. The lever lollo the curve of the said sect or, sliding beneath the same.

Fastened beneath the lever below the sector there is a curved spring 0, which having the shape of an arch the two ends slide on the board. This is to keep the lever raised up against the sector.

At the right of the upper end of the lever there is a screw with large hcad h, on which, almost touching it, there is a llat spring 1'. The clearance between the screw It and the spring Z is about the thickness of Bristol cardboard. At the lower right-hand side there is an electric battery j, fastened on the board by metal strap 1;, and on the top there is an electric bell l.

The wiring is done as follows: The wiring starting from the carbon goes to the bell, the other wire from zinc goes under the llat spring i, being in contact with the same, and the third. wire from button 7t to the bell again, and by pressing down spring i this coming in contact with button it will close the circuit, and the bell will ring.

It is to be understood that the wires run in grooves on the back face of the board, which being covered by magnet-covering cloth will make wires invisible. At the left-hand side of the upper end of the lever there 15 a cylinder in, containing a piston which is kept pushed by a spiral spring and controlled by a nut on the back. This is to push back the lever on its perpendicular position in case it should be shifted from left 'to right. At a distance of one-tenth of its length from the upper end of the sector there is a flat spring It, put upon a piece of metal of the same thickness of the lever, as shown by dotted lines. This is to hold the lever on that point when wanted. The handle 0 is for shifting the lever to point of F ig. 2 shows a cast-iron column 1, having on its top a piece of leather 3, held last by two screws same the lower end of the lever, Fig. I. Said column is situated on the opening-switches of railroad-tracks.

Let us place my apparatus at the righthand side of the tender of a locomotive and allow the same to run on'tracks which at a certain point has a switch that leads to a dead track on which cars are stationed. The locomotive running on first track, finding the switch left open by carelessness on the part of an employee, will certainly go ahead and wreck the cars standing on the siding. Let us now have this locomotive supplied with my apparatus, and we will find that as soon as the locomotive enters the switch the lower end (I of the lever will be pushed back toward the left by the top end 3 of the column. This pushing will cause the lever to go in a position shown by dotted lines, Fig. 1, and the top end of the lever, pressing down spring 'i on button 71, will cause the bell to ring, calling the attention of the engineer that he is running on a wrongtrack. Backing up the engine, the two leather ends (I, Fig. 1, and 3, Fig. 2, will come in contact again, and the lever will be pushed back to its previous perpendicular position, causirf 'thus the bell to stop ringing and the leverleady for another similar case.

In case the engine supplied with my apparatus has to go backward and forward frequently to avoid the bell from ringing often the engineer by means of handle 0 pulls the lever as far up as it can go, which will be at the point n when caught by the spring, as shown by the dotted lines, Fig. 1. h

hen the engineer is through maneuvering, he will push the lever in its proper place.

Having thus fully described my invention. 1 claim A In an electric railway signaling device with a bell, located in an electric circuit which is closed and broken by means of a I by hand when action of apparatus is not spring and a button, a, vertical lever oscillatwanted, a sector acting as guide to the circu- :0 ing on a stud, said lever provided with a, piece lar motion of'lever.
