CONDUIT-ELECTYRIC-RAILWAY SYSTEM.

SPECIFICATION forming part of Letters VPatent No. 549,580, dated November 12, 1895. Application filed July 14, l894.j Serial No. 517,511. (No model.)

T0 all whom 1f/may concern:

Be it known thatvl, BYRON E. OSBORN, of Auburn, in the county of Cayuga, in the State of New York, have invented new and useful Improvements in Electric-Railway Systems, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

Hy invention relates to improvements in electricrailway systems, and particularly to that class thereof provided with a main or power conductor for conveying an electric current to a terminal or trolley wheel mov-A able along the railway, and has for its object the production of a practical and simple de'- vice, which obviates the use of an elevated trolley-wire, the necessity of forcing a movable terminal or trolley wheel into contact with a main conductor, and the liability of contact of persons or animals with the main conductor, and their consequent subjection to an electric shock, which is often fatal.

To this end it consists, essentially, in a main conductor depressed beneath the surface of the road-bed, a series of secondary conductors above the main conductor electrically disconnected therefrom, a vehicle or car movable along the main conductor and provided with an electrically-operated device and a terminal for making contact with the secondary conductors, connected to said device for conveying the current therefrom, and an electric magnet supported by the vehicle or car for automatically connecting the main and secondary conductors.

The invention also consists in the general construction and arrangement of its component parts, all as hereinafter more` particu,- larly described, and pointed out in the claims.

In describing this invention, reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figures 1 and 2 are respectively top plan and side elevation of a portion of a railway system constructed in accordance with my invention, the truck of` a car or other vehicle being indicated by dotted lines as operatively mounted upon the rails of the system for supporting the parts of vmy invention designed to be carried by a movable vehicle or car. Fig.

3 is a transverse vertical sectional view taken on line 3 3, Fig. 2; and Fig. 4 is a longitudinal vertical sectional View taken on line 4 4, Fig. 3.

It is well known that electric-railway systems are provided with main or power conductors, which are Ausually either elevated above the road-bed or depressed beneath the same. Considerable difficulty is experienced in providing simple and practical means for conveying the current from the depressed conductors to a passing vehicle or railway-car, `and there is more or less liability of the entrance of foreign matters vwithin the conduits for the depressed conductors, and of the contact of persons or animals with such conductors, whether elevated or depressed.

My present invention is so constructed that a passing vehicle or railway-car is movable along a series of normally insulated or electrically disconnected secondary conductors of less length than the vehicle or car, and is automatically connected to the secondary conductor beneath the vehicle or car, thus obviating all liability of the subjection of persons or animals to an electric shock when passing over the road-bed of the railway system, as they can only engage the normally vinsulated or electrically disconnected secondary conductors.

A A represent the rails of my improved railway system, which each preferably consists of a series of sections electrically connected in the usual manner, so as to operate as a ground-conductor.

Bis a main or power conductor interposed between the rails A A, and O is a dynamo having one pole suitably connected, as by a wire c, to the conductor B, and its other -pole similarly connected to the rails A A, as by wires c'. The dynamo O is arranged at any convenient station along the railway, and the current generated thereby passes along the conductor B to the moving vehicle or car upon the rails A A, as presently described, and then returns along the rails A A to said dynamo.

The conductor B is supported in any suitable insulating casing D, which preferably consists of separable sections d dl, composed of wooden planks or other similar material, and having their adjacent faces firmly secured ICO together in any well-known manner. The sections (l d of the casing D are formed with longitudinal grooves d2 in their adjacent faces for receiving the conductor B, and are formed at intervals with pockets or chambers D', provided with removable walls D2, of suitable construction. lt is thus apparent that, although the greater portion of the conductor l is permanently insulated, the portions thereof arranged at intervals within the pockets D are exposed.

Arranged lengthwise above the conductor and preferably above the upper section (l ot its insulating casing D, are a series of secondary conductors E, which are electrically disconnected from each other and said conductor B. The secondary conductors E, which may be utilized as top walls for the pockets or chambers D', and may be separated from the adjacent wall of the casing D by insulating packing E, are formed of suitable material susceptible to magnetism, and are provided on their under faces with depending projections or pole-pieces c that are preferably secured to or formed integral with the upper extremity of a removable frame E2, having the opposite longitudinal edges of its upper extremity provided with engaging shoulders, suitably supported by shoulders on the lower faces of the conductors E, as clearly seen at Fig.

Arranged in proximity to the projections or pole-pieces c are a series of armatures E3 mounted on the upper ends of supports or levers c', pivoted at e2 to the frame E2, and having depending arms c2, provided with laterally-extending shoulders e4.

interposed between the supports e and the conductor B are a series of connecting-pieces ci", consisting preferably of levers pivoted at c to the frame E2, and having shoulders c7 arranged to make contact with the shoulders cLl of the armature-snpports c. The opposite end of the connecting-pieces c5 are provided with upwardly-extending arms es, having their free ends movable into engagement with the under face of the conductor B. Suitable fixed electric conducting-pieces EA1 connect the pivots c with the secondary conductors E for conveying the current from one to the other. The armatures E"g are normally disconnected from the projections or polepiece c, and the connecting-pieces e5 are normally disconnected from the conductor 13. lf desired, the wall D2 of any of the pockets or chambers D' may be removed, and the frame E2, carrying the corresponding armature E2 and connecting-piece c5, may be removed for examination, repair, or replacement of said parts.

As a passing vehicle or railway-ear passes over the road-bed oi' my improved railway system, the secondary conductors E are successively magnetized, as will be presently described, and consequently the depending projee-tions or pole-pieces e successively attract the corresponding armatures E and rock the supports e upon their pivots c2. As the supports e are rocked, as described, the connecting-pieces c5 are also rocked on their pivots e0, and the free ends of said connecting-pieces make contact with the conductor l and electrically connect the correspondin secondary conductors thereto.

At Figs. l and 2 I have illustrated by dotted lines the truck F of a vehicle or railwaycaras mounted upon the rails A A, and, as will be readily understood, this truck supports an electrieally-operated device as a motor G for propelling the same. The truck l is also provided with a suitable yielding snpport ll, here shown as a spring having its opposite ends secured to cross-bars j", having their opposite ends attached to the body-supporting bars f to the truck.

Secured to the yielding support ll is an insulating piece or frame 7i, which supports a magnet Il/ and terminals or trolley-wheels l l. The pole-piece H2 of the magnet ll moves in close proximity to or makes contact with the secondary conductors E for magnetizing the same and effecting the operation of the armatures E3, as previously described. This polepiecc may be of any desirable form, size, and construction, and is here shown as provided with a curved lower face and upwardly-extending extremities for facilitating its ready passage along the conductors E.

l preferably use two terminals or trolleywheels l I, arranged in front and at the rear of the magnet l-l', and preferably support these terminals or wheels upon an electric frame y1', having its opposite extremities provided with depending arms arranged one in advance of the other for supporting the trolley-wheels and having its central portion passed through the insulating-frame 7L and connected by a screw or other conductor i' to a wire or conductor i2, connected to a magnet y2, which is connected by a wire or conductor i" to a wire L, connected to the magnet ll', previously described. A wire 712 extends t rom the magnet ll' and is connected by a wire or conductor to one pole of the motor G. The opposite pole of the motor G is connected by a wire or conductor i" to one ol' the axles of the truck E, and the usual wheels f upon the axle f2 connect said axle to the rails A A. It is thus apparent that, when a secondary conductor E, connected to the conductor l, as previously described., is engaged by one or both of the terminals or trolley-wheels l, that the current passes through the magnets ll' i, and the wires or conductors 2 i* 7L h2 to the motor G and thence to the rails A, and that the magnets H' i2 and the motor G are energized. As previously stated, the magnet ll' operates to electrically connect to the conductor B the secondaryconductor E engaged with its pole-piece ll2, and the motor G operates to propel the vehicle or railway-car provided therewith. lt is evident, however, that instead of a motor G any other suitable electrically-operated device may be used.

In order to energize the magnet H' when the vehicle commences its movement, and before the secondary conductor beneath the vehicle is electrically connected to the main conductor B, I temporarily utilize a source of electric energy J as a storage-battery connected by wires or conductors j, h2, h', and h3 to the magnet H. The wires or conductors j h2 are normally disconnected until connected by a suitable switchj, which may be of any desirable form, size, and construction. The wires or conductors h 71,3 are normally connected by a switch j?, also of any desirable form, size, and construction, and provided with a movable piecej, having an armature j* secured at is free end and arranged opposite to the pole-piece of the magnet i3. As the switch j' is closed for completing the circuit from the source of electric energy J, the current passes through the wires j, h2, h, and h3 and energizes the magnet H, whereupon its pole-piece H2 magnetizes the secondary conductor engaged therewith, and said conductor is electrically connected to the conductor B. The current from the conductor B then passes, as previously described, to

-the motor G, and energizes the magnet i3,

which attracts the armature j4, and automaticallybreaks the circuit connecting the source of electric energy J with the magnet H', and, as previously stated, the current from the conductor B then operatesto continuously energize the magnet H.

l/Vhen, from any cause, the current from the conductor B is insufficient or the circuit to the motor G is broken, the magnet i3 is not energized sufciently to attract the armature ji and the circuit from the source of energy J to the magnet H is completed with the exception of the switch j. In again starting the vehicle or car, it becomes necessary to close the switch j for connecting the source of electric energy J with the magnet H' and effecting electric connection of the corresponding secondary conductor with the conductor B, and when said connection is established the switch j2 operates automatically to break the circuit from the source of electric energy J. The source of electric energy J may also be connected directly with the motor or other device G, if desired, by conductors J J2 J 3, and a switch J4 of any suitable construction. Itis also evident that, when desired to stop the vehicle or car, the wire i5 extending to the motor G may be first connected by awire k and a switch k to the wire i, leading to the axle f2, and the magnet IVI will not then lose its efficiency.

As will be readily understood upon reference to the foregoing description and the accompanying drawings, when a railway system is provided with my invention the main conductor is depressed beneath the surface of the road-bed and is thoroughly insulated, so that contact therewith is absolutely impossible; a series of secondary conductors electrically disconnected from each other and from the main conductor are arranged along the surface of the road-bed between the rails, a vehicle or railway car upon the rails automatically connects to the main conductor the secondary conductor directly beneath the vehicle or car, and no current is transmitted to the secondary conductors in advance or at the rear of the vehicle or railway-car. All liability of injury to persons or animals by contact with the conductors of the system is therefore entirely obviated, and the necessity for a lengthwise slot between the rails for permitting access of a terminal or trolley-wheel to a depressed conductor supported within aconduit is also entirely obviated. The connection of the vehicle or railway-car to the secondary conductors is under the control of the operator, and the car may be stopped or started at will. It is evident, however, that my invention is not limited to any particular form of electrically-operated device actuated by the main conductor, the exact construction of mechanism for connecting the secondary and main conductors, or the source of electric energy for effecting the initial connection of said conductors when the vehicle or railway-car is first started.

As it is evident from the foregoing that the exact construction and arrangement of the parts of my invention may be somewhat varied without departing from the spirit thereof, I therefore do not herein specifically limit myself to such construction and arrangement.

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