ELECTRIC RAILWAY.
SPECIFICATION forming part of Letters Patent No. 443,452, dated December 23, 1890.
Original application filed September 23, 1886, Serial No. 214,399. Divided and application filed June 1, 1887, Serial No, 239,930.
Again divided and this application filed September 1890. Serial No. 364,028. (No model.)
To all whom it may concern:
Be it known that I, RUDOLPH M. HUNTER, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Im- 5 provement in Electric Railways, of which the following is a specification.
My invention has reference to electric railways; and it consists of certain improvements, which are fully set forth in the following :0 specification and shown in the accompanying drawings, which form a part thereof.
This application (Case 169) is a division of my application, Serial No. 239,930, filed June 1, 1887, which in turn is a division of my application, Serial N 214,309, filed September The essential features of my invention, so far as the conductors are concerned, lie in the use of suspended working-conductors arranged along the track, combined with supply-conductors for supplying electricity to said working-conductors at intervals along their length. In connection with suspended conductors referred to I employ an electrically-propelled vehicle provided with an upwardly-extending current-collector device furnished with contacts making a continuous traveling under contact with the respective workingconductors. These workingconductors are bare and maybe made in the form of flexible cables, wires, or rods. The supplyconductors, which are directly connected with the source of electrical energy, may be insulated throughout their entire length and elec- 3 5 trically connected atintervals With the bare conductors, notwithstanding various d1tfer- 5o ences in the elevation between the said conductors and road-bed or railway, and the railway is lighted by electric lamps of any suitable construction, either incandescent or are, and the said lamps are coupled in multiplc with the supply-conductors by fixed connections, and, furthermore, are independent of the working-conductors. The supply and working cond uctors are preferably supported from poles arranged at intervals along the railway, and these electriclamps may be supported, also, upon these poles.
In the drawings, Figurel is an elevation of an electric railway embodying my invention. Fig. 2 is an end view of the current-collecting device, showing its relation with the suspended conductors; and Fig. 3 is a similar end View showing a modified arrangement of the collector-Wheels on the collector-arm.
A are vertical posts, of wood or metal, and support the working suspended conductors B B, which may be secured by the leverarms B These levers may be counterweighted, if desired, and are secured to the posts A; also, supported upon the posts A are supply-00nd uctors b, the said supply-conductors being connected to the electrical generator A, provided with a regulator A and also electrically connected at intervals with the working-conductors B 13- by means of branch conductors b. At intervals along the railway are electric lamps Q which may be supported upon the posts or poles A, and these lamps are in multiple connection with the, supply-conductors b. The object of the lamps is to light the electric railway independently of the lights in the electricallypropelled car.
A are the rails of the railway, upon which the electrically-propelled vehicle runs, and 0 are arranged parallel to the working-conductors. The car 0 is provided with an upwardlyext-ending support or arm 0, to which are journaled the collector-wheels 0*, said Wheels being directly insulated from each other and run against the under surface of the suspended oonductors B. 13, receiving current therefrom. The ca rt isprovidcd with a frame l3,sup1,tortcd upon its axles, and carried upon this frame is an electric motor I)", mechanically connected to rotate the axle of the car.
E is the motor-circuit, including the motor and a current-regnlator or resistancc'changer c, and has its terminals connected to the respcctive current-collecting wheels L.
In the construction shown in Figs. 1 and 2 the workingconductors l; i are illustrated as located at different elevations above the roof of the car. Idonot limit; myself to these locations of conductors and the collectorwheels, as they may be arranged in the rela tion shown in $3, in which the said conductors and wheels are substantially in the same horizontal plane. lhc working and supplyconductors are arranged at a suflicient distance above the railwayto be out of reach of persons walking thereon, and the car provided with upwardly-extending currentcollecting devices, preferablysupported from the roof of the ear. It will be seen from the construction herein set out that the same up wardly-cxtemlingeollcctor-arm (3 carries both of the electrically-independent contact devices C The construction of my improved system is such that through the compensation between the current-collecting devices and the working-conductors the collector-contacts maintain a continuous under running contact with the cond uetors, irrespective of the varying normal distances between the suspended conductors and the railway.
I do not confine myself to the details of construction of the means for supporting the workingconductors, nor to the particular construction of the current-collecting devices herein set out, as they may be modified in various ways without departing from the principles of my invention.
Broadly considered, my invention comprehends an electric-railway system wherein there are two separate working-conductors mechanically independent of the railwaytrack, combined with two supply-conductors, one for each working-conductor, and an elcctrically-propelled car provided with a current-collecting device indc iendcnt. of its wheels.
