Brake Applying Devices .Be it known that I, HARRY P. ZACKEY, a

- [citizenof the United States, residing at Martinsville, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Automatic for Railway- Trains; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' This invention relates to improvements in automatic brake applying devices for steam, electric, or compressed air railway trains.

The object of the invention is to rovide a device of this character by means 0 which the brake operatin mechanism of a train will be automatica ly actuated should the train for any reason run into an open switch or pass a danger signal.

'A further object is to provide an electric controlling device for the brake operating .mechanism of a train which will be set for .operation by the opening of a switch or the movement of a semaphore ordangersignal and which will be simple in construction positive and reliable in operation.

'With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a diagrammatic perspective view of a portion of a locomotive and a part of a railway track showing the application of the invention; Fig. 2 is a side view of a portion of'a railway track, showing the manner in which the electric operating mechanism is protected from .the weather; Fig. 3 is an end viewof the" electro-magnet protecting box or casing showing the cover operating mechanism thereof in an inoperative position and the cover closed; Fig. 4 is a similar; view showing the manner in which the cover crating mechanism is actuated to open the cover of the box.

Referring more particularly to the drawings, 1 denotes a portion of the cab and rear end of the locomotive, and 2 denotes the railway track. Arranged in the cab of the locomotive, is the usual engineers brake valve 3 which connects with the train air pipe 4 and the whistle air p1pe 5 (see Flg.

. locomotive, as shown.

1) whereby the air in said pipes is controlled to operate the brakes and the whistle in connected by a pivotally mounted lever 10 to an operating rod 11 which is slidably mounted in a suitable guide bracket 12 secured in proper position on the'sideof the On the lower end of the rod 11 is arranged a steel block 13 which forms the armature of an electro-magnet 14 hereinafter described. The upper end of the operating rod 9 extends upwardly and projects into the cab and is provided with an operating handle 15. of the rod 9 which projects into the cab is provided with a series of ratchet teeth 16 with which is adapted to be engaged a holding pawl 17 which is pivotally mounted. in the cab, as shown, and is adapted to be released or disengaged from the ratchet teeth The upper portion 16 by the hand or foot of the engineer to permit the operating rod to be forced downwardly to an operative position for closing the angle cock 7-.

The electro-ma-gnet 14 comprises a bar 18 which is connected with a series of magnet coils 19 whereby said bar 18 is magnetized when the coils are energized. The coils are arranged'in an electric circuit 20 which may be connected with any suitable batteries 21 or with any other source of electrical sup- .ply. In the circuit 20 is also arranged a switch or circuit closer (not shown), but which is adapted to be operated by the movement of a switch or the operation of a danger signal whereby the circuit 20 will plying the brakes. When the operating rod 9 has thus been projected upwardly, the

pawl v17 will play looselyover the ratchet teeth and will hold'the rodup and the angle cock open until released by the engineer or other person in the manor described.

In connection with the-magnet coils l9 and bar 18, I provide a hog; or casing 22 whereby phi said coils and bar are protecteci from snow or ice. The box or casing 2.2 is "provided with a cover 23 which is hinged to the outer upper edge of the box anfl has connected to its hinged edge operating links 2 the lower ends of which are connected to segmental gears pivot-ally mounted on the opposiee ends of the box 22 and in operative engagement with similar gears 26 also pivoted on the ends of the no. and which are connected with an operating plate 01" bar 2? arranged. on the inner side of the box adjacent to the outside edge of the track rail anci projecting at a suitable distance above the same and in position to be engaged by he ireaei of the locomotive Wheels whereby when the forward wheels of the locomotive pass over said or plate 2?, the same Wiii be depressed which in turn will operate the gears 25 and swing Lhr) cover of the box to an open position to eirgose the magnet bar 18 so that it will attract the armaeure biock 13 and operate the air releasing mechanism in the manner hereinbefore described. The segmental gears 25 anti 26 are provide with coil springs 28 which are adapted to actuate the same to close the COYGL of the box after Jhe train has passed oYer the same. v

From the foregoing description, taken in conneen with the accompanying drawings,

the constrgctic n an. operation of the inveniion, will be z'eaciily understood With-0171i) requiring a more extendeci'expianaiion.

Various changes in she form proposition and the minor details construction may be resorted to Without departing from flee principie or sacrificing any 01' the advantages of the invention, in. iii-e ap pended. claim. 1 4;

Having thus. ciescribed zn inaenion, What I cieim is:

in combination with the train'coniroiiing device of a railway train a verii caiiy movoperaiin connec' ceci'te said device, lever f L In of its and pivo rod, e verticaiiy necteci at its upper end to the said lever, :22: armature mentioned and an ranged adjacent the tract sairi in testimony my han in pzcesenee of two suoeeriioing Witnesses.
