RUDOLPH M. HUNTER, OE PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE THOMSON-HOUSTON ELECTRIC COMPANY, OF CONNECTICUT.

ELECTRIC RAI LWAY.

SPECIFICATION forming part of Letters Patent No. 424,928, dated April 1, 1890.

Original application filed July 14, 1885, Serial No, 171,625. Divided and another application filed March 12, 1889, Serial No. 302,945.

Again divided and this application filed January 10, 1890. Serial No. 336,548. (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 Improvement 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 specification and shown in the accompanying drawings, which form a part thereof.

This application (Case 127) is a division of my application Serial No. 302,945, filed March 12, 1889, which in turn is a division of my application Serial No. 171,625, filed July 14, 1885.

The object of my invention is to provide an electric railway with a branch track or turnout, and in which the conductor or conductors for supplying the current to the car are preferably separate from the rails for the supporting-wheels of the vehicle or car. The tracks are laid substantially as is customary, with the usual switches and branches or turnouts, and are supplemented by one or more separate or independent current supplying conductors, which may be arranged within a conduit or otherwise, and adapted to allow of a moving contact being made therewith by a suitable current-collecting device carried by the car traveling on the tracks. It is also evident that as there is considerable difficulty in laying the conductors parallel with the track the collecting device should be made to have a lateral movement independent of the carwheels to compensate for such unevenness.

In the drawings, Figure 1 is a cross-section of an electric railway and car embodying my invention. ing railway or turnout, and Figs. 3 and 4. show plan views of the working-conductors which are employed on the branch or turn-out and main line when embodying my invention.

A A are the two rails of the main track T and branch track or turn-out S, and these rails may have the usual switch-points U. Arranged parallel to these tracks is shown the conduits E, formed of the two sections E E, bolted together at e and forming the slot G 'at the top and made branching, as in the case Fig. 2 is a plan view of a branchof the rails. The conduit is supported upon blocks H and is tied to the stringers of the rails by rods f, by which a more or less fixed location is given to the conduit with reference to the rails.

C C are the conductors, one of which is connected with the positive pole of the generator B and the other with the negative pole of the generator. These conductors C C have preferably vertical or substantially vertical faces. The branch or turn-out is provided with a similar conduit to that of the main line furnished with conductors, and these 0011- d uctors thereof are connected electrically with the similar main-line conductors by connecting-conductors c c, or otherwise. By this means the conductors of similar polarity on both the main line and branch or turn-out are in multiple connection. The conductors of the main line and turn-out or branch are open at both ends to allow the free passage of the collector device from one pair of conductors to the other pair.

The only difference between Figs. 3 and at is that the polarity in the conductors of the turn-out in one case is the reverse of what it is in the other case.

H is the car or vehicle of any construction I having the usual supporting car-wheels for running upon the rails A. Suspended below the car in any suitable manner is a laterallymovable frame K, sustained by links N. Projecting down from this laterally-movable frame is a vertical plate or collector-frame K, which extends down through the slot G of the conduit, (when used,) and is provided on the bottom with brushes or contacts L L for making a sliding contact with the conductors C C within the conduit. The current collected by these brushes is conveyed by the motor-circuit p to the motor P, of any suitable construction and connected for driving the car. The collector, as an entirety, is movable to follow the irregularities in the conduit or conductors, (which need not be within a conduit, but may be supported independent of the rails in any suitable manner.)

Any matters set out in this application but not claimed therein are not dedicated to the public, but form subject-111atter of my applications above referred to.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
