UNITED. STATES PATENT OFFICE.
RUDOLPH M. HUNTER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE THOMSON-HOUSTON ELECTRIC COMPANY, OF CONNECTICUT.
ELECTRIC RAILWAY.
SPECIFICATION forming part of Letters Patent No. 429,093, dated May 27, 1890.
Original application filed September 23, 1886, Serial No. 214,309. Divided and this application filed September 11, 1889. Serial No.
(N0 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,
all of which are fully set forth in the following specification, and shown in the accompanying drawings, Which form a part thereof.
This application (Case 107) is a division of my application, Serial No. 214,309, filed Sep-i tember 23, 1886.
The object of my invention is to supply current to elect-rically-propelled vehicles from one or more suspended conductors extending along a railway, be they elevated above the vehicle, on a level With the roof of the vehicle, or under the vehicle.
In carrying out my invention I provide one or more suspended conductors, extending along the railway, each having its under side unobstructed for the free passage of a current-collecting device; and upon the electrically-propelled vehicle I mount a currentcollecting device making an under contact with the conductors and having'provision for -lateral movement at its free end or that which is adjacent to the conductor or conductors. The contact portion for making direct connection with the conductor is preferably a deeplygrooved wheel which receives the conductor within its groove, and thereby insures the conductor remaining in contact with the said wheel. Any form of ,contact device may be used. The conductor guides the collector, and vice versa, so as to keep both in working connection. The collector may be carried upon the axles independent of the car-body, if so desired.
The foregoing are the essential features of my invention; but various details of my invention are set out hereinafter.
In the drawings, Figure 1 is a diagrammatic view illustrating my invention with the suspended conductors arranged above the ve hicle. Fig. 2 is a cross-sectional view illus trating the location of the conductors on a level with the roof of the vehicle. Fig. 3 is a cross-section showing the wheels and axle, collector device, and conductors, the latter being arranged under the vehicle. Fig. 4 is a diagrammatic side elevation corresponding to Fig. 3; and Fig. 5 is a cross-section showing the support of the conductor from above, and
suitable manner, so as to expose a smooth or practically smooth and unobstructed under surface. They are preferably flexible. As shown in Fig. 5, these conductors are held from above by arms extending from the posts C. The particular method of support is immaterial to my invention, beyond the fact that it must permit a continuous or substantially continuous contact by the collector with the under surface of the conductor.
D is the generator for supplying current to the conductors B. If desired, one suspended conductor B maybe employed as the supplyconductor and the return-conductor may be the rails, as indicated in Fig.1 by the dotted connection between the generator and the rail.
E is the vehicle or car, and is supported upon axles N by springs, in the usual manner. It is supplied with an electric motorF, geared in any suitable way to the axles to enable its propulsion.
I I II are the grooved contact-wheels for making a running under contact with the conductors B. These Wheels are deeply grooved, so as to receive the conductors and enable the one to be guided by the other, and thereby insure intimate and constant contact. These contact-Wheels are insulated from each other and supported by a frame or arm I, carriedby the vehicle and capable of lateral movement relatively to the said vehicle, so as to compensate for the varying locations of the conductors. This arm or frame Iis vertically adj ustable in a frame or primary part J and held by a set-screw K, so as to move the contactavheels vertically with respect to the conductors. The frame J is secured to a transverse cross bar or slide L, which is guided in the bearings or journals M, carried by the vehicle and, if desired, upon the axles N. By this construction the collector as a whole may move laterally to compensate for any variations of the conductors. The arm or frame I is provided with insulated conductors 71, leading from the motor circuit P to the contactwheels II.
I do not limit myself to the mere details herein set out, as they maybe varied in many ways without departing from my invention.
The under-contact collector has many advantages in practice over upper-contact collectors, since it simplifies the construction of the road equipment and cheapcns the cost of construction.
Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is
1. The combination of a railway, a. suspended electrical conductor extending along said railway, a traveling vehicle for said railway, and a laterally-adjustable eurrenteollecting device carried by the vehicle and making an under contact with the conductor.
