SPECIFICATION forming part of Letters Application file'd May 2, 1887.

Be it known that I, GRANVILLE G; WooDs, a citizen of the United'States, residing at Cincinnati, Ohio, have invented new and useful Improvements in OverheadCondueting Systems for Electric Railways, of which the following is a specification.

My invention relates to travelingelectric contacts and overhead conductors employed in electro-motive railways; and it consists in illustrated.

Mechanism embodying my invention is shown in the accompanying drawings, in which- Figure 1 is a plan view of the carriage; Fig; 2, a cross-sectional elevation of the suspended. conducting-wireswith one of the hangers supporting the same, and an end view of a carriage in position; and'Fig. 3, a side elevation of a carriage inposition;

-Referring now to the drawings, the electric ing-wires carried upon insulated hangers 4. I The hanger terminates below in two upwardlyprojecting arms, 5 6, thesetwo arms carrying upon their upper extremities iron wires 1 and 2, and between the two arms at the lower extremity of the stem4 is carried a copper wire, 3. Thecontact carriages for a donbletrack and 2, while the central wire, 3, carries the transmitted't'hrough the metallic arms 5 and 6 to the wires 1 and 2. By this construction I am able to utilize lighter wires, yet obtain a largely-increased conducting capacity and consequently less resistance.-

The carriage consists of a light frame, preferably of cast-iron, consisting of two side pieces, 7 7, connected by cross-braces S 8. Between are carried the grooved running-wheels 1O 11 12, the two latter being secured in a pivoted truck, as shown. The object of the latter arrangement is to preserve a constant electrical contact without danger of interruption from wires or any accidental causes. The sides of the carriage are extended downward and some Patent NC. 383,8 t4. dated May 29,1888.

Serial No. 23 ,776. (No modeLi ,to the central vertical plane of the carriage and its carrying-wire, for the attachment of the car-connection. ,Connection'is made with the car by means -of a spring-clamp, 13, attached by means of a wire cable, 14, to the ttaveling carriage. The clamp is a piece of spring metal in U form 6:. with itsjaws broughttogether, as indicated in Fig.3. Its clamping power is suliicient tomaintain the connection with the ear, yet to give way and release the carriage in case of an accidental stoppage of the carriage without injury to the conductingline;

I claim as my invention anddesire to secure I by Letters Patent of the United States 1. An overhead conducting'path for electro-motive railways, embodying, essentially, a central conductor carried by insulated metallic brackets, and one or more wires for carrying the contactcarriage, held upon suitable arms of said brackets, whereby the current delivered to the first-named conductor is transmitted by and through the bracket-arms to the carryin g conductoror conductors, substantially as set forth;

2. In overhead conductors for electro-motive railways, the combination of an insulated suspending-braeketwith three conducting-wires:- to wit, a central wire'eonnected with the generator and two others supported upon outer arms of the bracket and receiving their charges tact-wiresand transmit'the current from the first-named to thesecond conductors, substantially as set forth.

4. A traveling contact or carriage for over we head-conducting systems for electromotive. ing a still lower central extension-curved inrailways, consisting, essentially, of two conward to the central vertical plane of the car- :5

ducting side plates or frames joined at the top and carried upon three grooved rollers pivoted 5 between the plates, two of said .rollersjheing I carried in a truck so pivoted,xsnbstantially .as set forth.

5. The traveling contact-carriage for overhead-conducting systems for electro motive to railways, embodying, in combination with its carrying-r01 lers,two side plates joined together at the-top, flaring-outward below and at the forward and rear entls, one of said plates havrying-wheels and adapted to receive the mo tor-connection at the lowest central point-,sub: stantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing wit-- 2o messes, I I
