ELECTRIC RAILWAY.

SPECIFICATION forming part of Letters Patent No. 468,165, dated February 2, 1892.

Application filed December 1, 1891. Serial No. 413,723. (No model.)

.To @ZZ whom zit may concern:

Be it known that I, MALONE WIRELESS, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Electric Railways; 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart ot' this specification.

Figure l represents the system diagrammatically. Fig. 2 is an end view of the' trolley, the axles being arched.

This invention relates to an improved systern for an electric railway, designed more especially for underground work.

In the annexed drawings, the letters A A indicate the two lines ot' a railroad-track. Runnin g along between these rails is the bare working conductor I3, made in sections h, insulated from one another at I2. From the generator G an insulated main power-line C runs along the trackand has the ground D. From each section h of the working conductor B a feed-wire F. runs to one end c of the armature c of an ordinary telegraphic relay e2, such armature having a carbon contact e3 at the other end. Adjacent to the contact c3 is another carbon contact ci, from which another feed-wire E runs to the insulated power-line C. Running parallel with the working conductorB-one on each side thereof-are two bare wires F and G, made in insulated sections f and g, coincident with sections b of the 'working conductor B. From the sections 4o f of the wire F groundingsf' run to one line of rails A. From the sections q of the wire G a wire Il runs to the magnet ci ot the relay e2, and thence to a supply-line C', which is connected to a battery c', having the ground c2.

On the track is the car I, having the usual motor K, connected in the usual way. Se-

cured underneath the car I is the trolley L.

This consists of the two transverse axles M M', carrying the wheels ZZ Z2 m m m2. These axles are provided with insulators lo 7o', so that each axle is divided into three parts and each wheel on an axle is thus insulated from the others. As shown, the middle wheels may be larger than the others. The two middle wheels Z' and m are electrically connected by the wire Z3, and the wheels Z and m and Z2 and m2 by the wires miE in". From the wire Z3 a feed-wire Z4 runs to the motor K, and from the wheels Z and Z2 or the ends of the axle M wires Z5 m5 run to a switch N on the car. This trolley L when in place has its wheels Z and fm on the bare working conductor B, its wheels Z m on the wire F, and its wheels Z2 m'2 on the wire G. In a system thus constructed the magnets e5 are vitalized by the current from the generator G, passing through the rheostat e2, and the main current is taken from the main power-line C, as will be described. \Vhen the motor-circuit on the car is closed in the usual way and the switch N also closed, the action is as follows: The cu rrent from the battery c passes through the wire C', the wire Il, around the magnet e?, vitalizing it, through section g of the wire G, wheel m2, wire m", wheel Z2, wire m5, switch N,

wire Z5, wheel Z, wire m3, wheel in, sections f of wire F, grounding f', and rail A to ground. As soon as the magnet e5 is vitalized, the armature e' is drawn down and the power-current streams from the power-line (l through the feeders E and E and armature c' to the section b of the working conductor B, and thence through the wheel m and wires Z3 and Z1L to the motor. The trolley is made with two sets of wheels on separate axles, so as to span the insulation of the wires on which it bears. This system produces a simple and efficient device. The circuits on the positive side, being all wire, eitectually prevents grounding until the current has been used.

Having described my invention, what I claim isn A prime conductor or power-line, an electrical battery and a su pply-line running therefrom, a working conductor, a positive wire, and a negative wire, all three in sections insulated from one another, the sections of the negative wire grounded, the sections of the positive wire connected to the supply-line from the battery by feeders in which are electro-magnets, and the sections of the working conductor connected with the power-line IOO by feeder-wires, parts of which are the armatures of the said electro-magnets, in combina.- tion with a car provided with a trolleyiu electrical Contact with the Working conductor, posi- 5 tivo and negative Wires, and. also provided l In testimony whereof I affix my Signat-11min presence of two Witnesses.
