ELECTRICAL SIGNALING APPARATUS FOR ENGINES.

Specification of Letters Patent.

which it appertains to make and use same,

reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in electrical signaling apparatus forrailway locomotives, etc., and consists in the provision of various details of construction and combinations and arrangements of parts which will be hereinafter fully de-.

scribed and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a locomotive, showing the application of my invention. Fig. 2 is a diagrammatic view showing the electrical connections with the axles of two locomotives, and Fig. 3 is a diagrammatic view showing the connections between the insulated axles and the electric bell and bat- 'termediate track.

0 designates an axle section adapted to be mounted in suitable bearings upon an engine and the outer end of said axle section O is connected through suitable insulated collars C with the axle sections D. The axle section 0 has a flanged wheel E fixed thereto, which travels upon the intermediate track B, and the axle sections D have wheels F which travel upon the outer rails A. Each axle section has a collar G loosely mounted thereon and a binding post G projects from said collar to which a wire H is connected as shown clearly in Fig. 2 of the drawings. Said wires are in turn connected tothe binding posts 0 of the electric bell apparatus 0 and to the battery Q. The apparatus upon either side of the intermediate rail is similarly connected electrically with a bell and battery, as shown in the drawings, and each engine is adapted to be provided with similar apparatus.

It will be noted that in Fig. 2 of the drawings, I have shown the axles and apparatus representing two engines approaching from opposite directions. In the apparatus at the right in Fig. 2, are the flanged wheels F traveling upon the rails A and the outer axle sections D upon which said wheels F are mounted, and to each axle section D is loosely mounted a collar G to which a binding post is connected having secured thereto a wire 9, which in turn is connected to a binding post O thence connected to the battery Q. A second wire H is also connected to the battery Q and leads to a binding ost upon a collar G upon the axle section (i to which is keyed a flanged Wheel E running upon the middle rails B.

In tracing the circuit, the current leads from the battery Q through the bell apparatus O, thence to the collar G, to the outer axle section D, through the wheel F and outer rails A, to the outer wheel F of an approaching locomotive, through the shaft D collar G to the bell O thence through one of the binding posts O to the battery Q and returning through the wire H to a collar G upon a shaft O thence through a wheel E rails B, to the wheel E, through the axle C, to the bell O and battery Q. It will be understood that the electricity for furnishing the current to the two approaching locomotives will be through the two batteries, each exerting its share of the electric force to cause the bells to be in circuit when the engines a proach each other near enough to form a suicient force to cause the alarms to be sounded.

WhatI claim is A signaling apparatus for railway locomotives comprising, in combination with three parallel rails, stub axles, bearing arms adapted to be supported by a locomotive and in which the inner ends of said axles are j ournaled in suitable insulated bearings, stub axles also journaled in the outer ends of said bearings, wheels upon the stub axles desame and the binding posts of said collars, as shown and described.

In testimony whereof I hereunto afiix my signature in the resence of two witnesses. GE RGE J. EXTERKAMP.

signed to travel upon the outer of said rails, a double flanged wheel mounted u on the intermediate of said stub axles and esigned to travel upon the middle of the track, collars mounted upon the stub axles, a binding post projecting from each collar, a setscrew fitted to each binding post, an electric signal, and circuit connections between the
