ELECTRIC RAILWAY.

SPECIEICATIONionning part of Letters Patent No. 386,085, dated July 10, 1888.

Application filed January 25, 1856. Serial No. isanrn. (No model.)

To all whom it may concern.-

Be it known that I, ELIAS E. Bins, of the city of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Electric Railways, of which the following is a specification.

This invention relates to certain improve ments in electric railways of that class in which the propelling-current is conveyed to the motors or cars by means of electrical conductors extending along the line of the railway and carried in a suitable conduit.

The said invention is more particularly adapted to and designed to meet the require ments of electric street-railways; bntit is also applicable to and intended to be used for elevated, suburban, and other railways.

The first part of my said invent-ion consists in the combination,with the conducting-rails, which are contained within a suitable conduit, of contact-wheels arranged to be moved in a horizontal plane, so that by simply turning the pendent bar, to which the said wheels are indirectly connected, by means of any appropriate mechanism, from the platform or other part of the car the direction of motion of the car can be changed or the car stopped.

The second part of my said invention consists in a novel construction and arrangement of the devices whereby the pendent bar carrying the contact-wheels is supported and guided from the car-body, and also in means for deflecting from the said contact-wheels any water which may adhere to the sides of or enter the longitudinally-extending slot in the conduit at a point immediately above the said wheels.

The third part of my said invention consists in the novel construction and arrangement of certain details of the devices above alluded to, whereby they are peculiarly adapted to the uses and purposes for which they are intended, all of which will hereinafter fully appear.

In the further description of the said invention which follows, reference is made to the accompanying drawings, forming a part hereof, and in which Figure I is a partlysectional side elevation of a street-railway car provided with myiinprovcments. Fig. II is an exterior end view of the lower portion of the said car, on an enlarged scale, and a transverse sectional view of the road-bed, showing the conduit and the current-collecting devices. Fig. III 1s a partlysectional top view of the conduit and the contact-wheels, and illustrates different positions which the said wheels may occupy with re spect to the conductinga'ails. Fig. IV shows two views of the contact-wheels and their sup port. Fig. V consists of two views of parts of the starting and stopping mechanism. Figs. VI and VII illustrate i'nodiiications in the construction of the conduit. Fig. VIII shows a modified construction and arrangement of the contact-whcels and their attachments.

Referring to Figs. I to V, inclusive, A is the car-platform, and B B are the car-wheels.

G 0 represent the track-rails, which rest on the string-pieces a a, secured to the cross-tics Z) Z) in the usual manner.

D is a metallic conduit of any suitable construction, but preferably of the form shown. This conduit may have its sections or lengths formed in two parts, as shown in Figs. II and VII, or in a single piece, as illustrated in Fig. VI, and is firmly secured to the cross-ties by means of bolts or other suitable means. The inner sides of the conduit are faced with asphalt, concrete, or some other non-conducting and non-absorbent substance, in which the conducting-rails c c are embedded, the rails being flanged, as shown, to secure a good hold therein. Thisconstructionofthec0nduit,however, is not essential to the proper operation of the current-collecting devices, hereinafter described, as said devices may be used equally well with other forms of conduits-such, for instance, as shown in my application of September 17, 1885, Serial No. 177,379, and also wherever two parallel conducting rails are employed. The non-conducting substance may, however, be merely interposed between the rails and the sides of the conduit. The body of concrete or asphalt is held in place by means of projections (Z (Z on the inner surfaces of the conduit. The upper exterior surface of the conduit is also provided with a bed of asphalt or concrete, E, which is practically on alevel with the pavement or street surface, which is represented by F. To admit of the application of this bed of concrete or asphalt to the surface of the conduit, the said surface of used.

the conduit is situated somewhat below the pavement and fitted with projections ee, preferably of dovetail shape, as shown in Fig.1I, and the approaching edges of the upper plates of the conduit, which are separated to form the longitudinally-extending slot f, are provided with upward-projecting beads g, to re tain the inner edges of the concrete, the lower edges of the heads 9 extending slightly into the conduit, as shown, to prevent any water entering the slot from running down the side walls thereof. This construction of the slotopening also gives a broader bearingsurface to the traveling frame that supports the contact devices. The conduit may have partitions h, instead of the projections d d, to re tain the concrete or asphalt E in place, as shown in Fig. VI, if preferred. In this figure I have shown the interior exposed metallieportions of the conduit covered with a protective coating of enamel, asphalt. or other similar non-conducting water-proof material, the object of this coating being to prevent any escape of current from the rails to the conduit due to the entrance of foreign matter or moisture. When the conduit is to be applied to an elevated railway, its lower plate can be provided with holes or openings z', of any suitable shape and size, to admit of the escape of water entering the conduit through'the slot f. In underground conduits the water is carried off through pipesj, one of which is shown in Fig. II in dotted lines. The pipe leads to a sewer, which is not shown.

G is an electric motor,of any approved con-' struction,seeured under the platform A of the car. The main shaft k ot this motor is fitted in the present instance with asprocket-wheel or chain-head, Z, which is united to a larger sprocket-wheel, m, on the axle n of the car by means of a chain belt, 0, though it is obvious other arrangement of driving-gear may be This chain is shown only in Fig. I.

H is a vertical bar supported in suitable bearings, pp, with a handle, g, at its upper end, which is within convenient reach of a person standing on the platform A of the car. Attached to the lower end of the bar H is an arm, 0", which is united by means of a link, I, to a similar arm, 8. at the upper end of a second vertical bar, J, which carries the contact or current -collecting devices, hereinafter described. The bar J is sustained by a guide frame or bracket, K, which in the present case is rigidly connected to the bottom of the car by means of a hanger, L. To avoid irregularities in practical operation due to movement of the car-body on its springs, the frames may be secured toabridge-piece spanningthe two axles, as may also the motor, as shown in my application for Letters Patent, Serial N 0. 177,379. The body of this frame K is of such thickness as to pass loosely through the slot f in the conduit, and the frame is in two parts or sections, t and u, the adjacent edges of which are hollowed and separated to form a I cavity, 12,1"01' the reception of the bar J. (See particularly Fig. IV.) The bar J is preferably. supported directly below the center of the axle, in order that it may not be thrown out of alignment with the center of the slot when the car is rounding a curve.

M is a yoke secured to the lower end of the bar J, to which the cont-act devices are fastened. These contact devices consist, preferably, of wheels N and 0, having pivotal bolts w and m, which are insulated from the yoke M and connected by the leading-wires P and Q to the motor, (see Fig. I;) but brushes may be substituted for the wheels N and 0 without departing from the spirit of the invention. The leading-wires preferably, but not necessarily, pass through the body of the frame K, and are insulated to prevent metallic contact therewith. i

The motor G is preferably of such construe tion that by simply changing the direction of current flowing through it from the line-conductors the armature can he made to turn in either direction, and consequently propel the car either forward or backward, as desired. I may, however, employ for this purpose a 1110- tor having permanent field-magnets,'or one whose field-magnets are separately excited in any suitable manner.

In Fig. III the positive and negative conducting-rails are respectively denoted by and as are also the contact-wheels connecting with the positive and negative terminals of the electro-dynamic motor.-

It will be seen by reference to Fig. III that the wheels N and 0, (represented toward the left of the said figure,) respectively, are in contact with the positive and negative rails,while their delineation at the right of the said figure shows a reversed position. The central representation of the wheels shows them to be in a neutral positionthat is to say, they are not in contact with the rails-and the electrical current to the motor is therefore broken.

From the foregoing description it will be understood that by simply turning the handle 9 in the proper direction the contact-wheels can be made to assume any of the three positions shown in Fig. III, thereby interrupting or changing the direction of the current flowing to the motor and causing the ear to he stopped or driven forward or backward, as desired.

To prevent accidental detachment of either or both of the wheels N and 0 from the coir ducting-rails c e, owing; to the jarring of the car, irregularities in the surfaces of the rails, or from any other cause, I propose to hold the wheels or brushes, as the case may be, to the contact-rails wit-h a yielding pressure; and to this end I provide the arm 8 with a hollowfaced lug, It, and interposed between the lug and some stationary part of the car a spring, S,which projects within thehollow face of the lug, as shown in Fig. V. W'ith the partsrelatively placed asshown in the said figure, the contact-wheelsare held normallyin the neutral position; but as the arm 8 is turned in either IIO direction the spring is compressed until the corner of the lug it has passed the center of the spring S, when the spring recoils and places a tension on the lug in the same direction in which it has been moved, and the wheels I? and 0 are by this means held uniformly and constantly in contact with the conduit-conductors irrespective of any jotting of the car or unevenness of the conductors. To still further insure absolute contact with the conducting-rails, the yoke. M, as shown in Fig. VIII, may be provided with a smaller yoke at each end, to each of which two contact-wheels are attached, and to limit the movement of these supplemental yokes they are furnished with pins .2, which pass through slots in the yoke M.

To carry water entering the slot f directly over the wheels N and O past 0 away from the said wheels, I curve the lower end of the frame K, and provide it with a tlange, y, as shown particularly in Fig. IV.

At T, I have shown a s\vitch-box,which may be attached to any convenient part of the car. This switch-box may be employed when it is desired to utilize a portion of theelectrie current flowing through the wires I and Q for other purposessuch as for lighting, heating, or applying the brakes to the car. In such case the proper connectionsare made with the wires P and Q and lead to the switch-box, from which the current may readily be directed into the desired circuits. In the present instance the switch-box is included in the motor-circuit, and is designed to be used for opening this circuit in case of accident or in the event of repairs being required.
