T0 all whom, it may concern:

Be it known that I, 'WILLTAM M. SCHLES- INGER, a subject of the Queen of Great Britain, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new `and usef'fi. Improvements in Electric Pai'iways, of which the following is a specification, reference being had therein to the accompanying drawings, ,wherein- Figure l is a longitudinal sectional view, partly in elevation, of a portion of a car and line of way of an electric railroad embodying my improvements. Fig. 2 is a detail elevation showing one of the lamps for the car unscrewed from its holder or removed from the ear-lamp circuit. Fig. 3 is a view similar to Fig. 1, showing the sera-pers and. brushes on the traveling frame connecting the line and car-motor circuits and modified arrangement of circuit for the car-lamps. Fig. t is an enlarged view of said frame and of the conduit for the line conductors. Fig. 5 is an enlarged sectional elevation of the contact-rollers, their spring-supports, and the lower part of the traveling frame. Fig. t is a transverse section, partly in elevation7 of the conduit, the line conductors, and the traveling frame. Fig. 7 is a like view showing preferable forni of conduit whenv ceateu adjacent to one of the track-rails, and also preferable mode of construction of line conductors and insulating devices therefor; and Fig. S is a longitudinal section of a portion of the conduit, showing a construction of manholecover and line-conductor connections at the manholes located along the line of way of the conduit.

My invention has relation to electric railways, comprising line conductors fed from a generator located at a station or stations along the line of way, and cars having a inotor-eircuit and traveling frame connecting the motor and line-circuits; and it has for its principal objects to provide an inexpensive, simple, and durable conduit for the line conductors, to thoroughly insulate the latter from the conduit; to so constructing line conductors that they afford as little resistance as possible to the passage of the linecurrent and yet present hard or d urable wearing surfaces for contact with the brushes or rollers on the traveling frame or connections of the ear; to providing the conduit with manholes having covers to which are affixed sections of the line conductors and arranging the latter at the manholes to permit their covers to be removed Without breaking the line-circuit; to provide the car with traveling connections arranged and constructed to insure positive contact between the car-motor and the line-circuits under varying conditions of travel or service, and, Vfinally, to electrically lighting the cars by a current which is either a division of the line-current or the current passing to the car-motor, or, in other Words, the current for lighting the ear is independent of or dees not pass to and through the car-motor.

My invention accordingly consists of the combination, construction, and arrangement of parts comprising an electric railway as hereinafter described and claimed, havin g reference particularly, first, to a conduit composed of two vertical side pieces of, preferably,wood connected by suitable inside crossbars or brackets and stayed by outside brackets, and of top bars with central slot between thern,and having an upper lining or surface of metal and an under support for the line conductors; second, to compound line conductors composed of two different kinds of metal, or of a copper and an iron or steel plate suitably joined together and offering different resistances to the passage of the current; third, to line conductors fastened to rubber or other insulating blocks or supports inelosed in a fiber trough or casing suitably attached to the conduit; fourth, to a manhole-cover having aiiixed sections of line conductors provided With contact-springs; fifth, to a ear traveling frame or connection composed of a wheeled carriage traveling or rolling along the top of the conduit and having spring supported rollers or brushes which bear against the line conductors, and, sixth, to a car-lamp or other electric circuit having either its separate traveling brush or connections with the line-circuit or divided from the motor-circuit in advance of the motor.

In the. drawings, A represents a line of track for an electric railway; fl, the conduit TOO for the line conductors C; D, the car having electric motor d in gear with the car-axles in any suitable manner, anfl F the. tr.: 'cling frame for the connection.J between the carmotor circuit I I and line conductors C.

The conduit l5, when placed in the center between the tracks A, is preferably composed of two vertically-arranged sides b, of wood or other desired material, connected by inner metal cross-bars or brackets Z2', of preferably an inverted-U shape, as shown more plainly in Fig. 6. These brackets are screwed or otherwise attached to the side pieces b, The latter are preferably laid upon the cross ties if of the tracks, and are secured to and stayed or braced thereon by the outside i'astening or rightangle brackets b". Upon the top of the side pieces l) are placed, preferably, covers or bars L5, arranged to have a central longitudinal slot b between them. These covers when made of wood have upon their upper surfaces metal plates or faces 217, and upon their under surfaces the insulated blocks b for supporting the line conductors C. IVhen the covers or bars U" are made of metal, no facin gs or linings are reeuiref: The lower part of the sides o"l lne slot b is protected by metal facing-strips b", which extend downwardly into the conduit to or below the lower edge or plane of the conductors C, to protect them from the weather and from dirt or other material entering or thrown into the conduit. The bottom of conduit I3 may at intervals along its length have outlet pipes or drains bm, (see Fig. (5,) for connection with a sewer or other like iixture.

Any suitable form of conductor C may be employed. In most of the figures of the drawings I have shown a conductor which is seg mental in cross-section, as I prefer this form. To provide a conductor of iow resistance and of great durability, I prefer to make it of two parts or sections of different metals having different degrees of hardness, (see Figs. 7 and 8,) wherein the outer or larger section c is of copper and the inner section c is of iron Or steel. rlhe former or copper strip conducts the current and the latter forms a hard contacting-surface for the brushes or roll-irs on the traveling frame IC. These sections may be connected together in any suitable manner to form stiff or rigid lengths of conductors C. To thoroughly insulate the latter, I prefer to secure them to india-rubber blocks b, ineascd in a trough c2, made of fibrous or analogous material, (see Fig. 7,) and cement or otherwise secure the saine to the top plates b5 of the conduit. The adjacent or opposing faces of the troughs c2 are lined with tin or metal c3 to protect them against the weather and against wear or damage bythe insertion of dirt or fixtures into the conduit or its slot.

IVhen the conduit is placed to one side of 'the longitudinal center of the tracks or adjacent to one of the track-rails, one top plate of the conduit and one of the rails are formed in one piece, as shown in Fig. 7 and the re,

maining top plate is belted or otherwise fastened to the transverse sleepers orties lf.

Along the conduit, at suitable intervals,

are manholes F, at which places the conductors are broken and electrically connected by a wire f. The broken or filling-in sections C of the conductors are secured to the manhole-covcrf" and are provided with springfingers f2 ior making electrical contact between sections C and the adjacent ends of conductors C when the cover is in position upon the manholes. This described construction provides easy access to the conduit without breaking the electric connection of the liuc conductors and affords a continuous eircuit throughoutthe conductors when the inanhole-covers are or are not in place.

The traveling frame E is composed of a slot iron or bare, mounted upon wheels or rollers e', which travel upon the top plates U of conduit I3 or their metal linings 11T. Said frame may be attached directly to the car, as indicated by dotted lines E', Fig. 23, to a frame E2, mounted upon the car-axles, or to the car by means of cords or rods E3, or to axles by means of said cords or rods, as indicated in Fig. fl or anycther suitable connection of saidfranie F, with the car may be made whereby as the car moves the frame travels therewith. The frame-rod e depends through conduit-slot b below the conductors C, and is provided with, preferably, a bifurcated end c2, into which is suitably keyed a cross-bar ci". Upon the ends of bar e3 are attached blocks e, to which in turn are secured curved springs or elastic bars 25, having at their extremities rollers or wheels c, as shown in Fig. 3, or brushes or rubbingblock, as indicated in Fig. l, which rollers or brushes are adapted to the inner er lower surfaces of the conductors (l to make electrical contact therewith for the car-motor circuit I I. The springs are so disposed in relation to frame rollers or wheels c' and contact rollers or brushes c that the former are drawn down upon or impinge under pressure against the top surface of the conduit, and the latter have an upward forcible contactagainst the conductors C, whereby said rollers and brushes are maintained at all times in close or hugging contact with the surfaces against which they impinge. At the same time the elasticity of the springs is such that they admit of either the rollers e or the contact-brushes e. yielding to the inequalities of the conduit and conductors without breaking contact.

To keep the top of the conduit free :from obstructions or from dirt in the line of travel of wheels e', brushes (i are secured to the frame E or its longitudinal arms in advance of said wheels.

To keep the conduit-slot b open er clean, I attach Scrapers or knives II to the arms ci of frame E. These knives or Scrapers deF pend into the conduit-slot and free it er its sides from anyaccumulation of dirt.

Brushes G and Scrapers II are attached to IOO IOS

IIO

bothl ends of frame E to act as the car moves either forwardly or backwardly.

The lamp-circuit I oi the car may be a loop from the motor-circuit I I', as indicated in Fig` 3, and have a cut-out o r switch fi, or it may have its own separate traveling frame or connections K, as illustrated in Fig. l, which frame is constructed and arranged fc operation, as above described, 1" or trame E. rlhis lamp-circuit may have a switch or cutout, as indicated by dotted lines e' in said iigure, or a high resistance i may be placed in the circuit around each lamp, so that when any of the lamps are removed from their holder, as shown in Fig. 2, the circuit is still complete, though the lamps are out of such circuit. If desired, the lamp-circuit may be used for other than illuminating purposes.

The provision of a separate light or lamp circuit having individual traveling connections with the line conductors makes the current supply for the lights independent of that 'for the motor, and this is a practical advantage in electric railroading for -the reason that any defect either accidentally or otherwise happening to the motor or its traveling connections at night or when the lights are burning they still continue to burn while the defect in the motor or its connections is repaired, if capable oi repair, and if not the light-circuit and its traveling connections ca then be used for the motor as "veli as ior the lights by making suitable connections, and

ltravel of the car continued, thereby preventing blocking of the line.
