ELECTRIC TROLLEY DEVICE AND CONDUCTOR CONSTRUCTION THEREFOR. v

SPECIFICATION forming part of Letters Patent No. 588,145, dated August 17', 1897.

- Application filed. January 20,1897. Serial No. 619,978. (No model.) 7

To 00% whom it may concern:

Be it known that I, SAMUEL HARRIS, of Johnstown, Cambria county, Pennsylvania, have invented certain new and useful Improvements in Electric Trolley Devices and Conductor Construction Therefor, of which the following is a specification.

My invention relates to trolley devices of the class adapted to be carried by a moving vehicle to establish contact with a suspended conductor.

The object of my invention is the provision of an improved trolley which shall be more durable and eifective than those now known to the art. 7

To this end my invention has for its central feature the provision of a large contact-wheel horizontally swiveled, so as to follow lateral variations in the position of the conductor by merely turning on its own axis.

My invention also provides an improved conductor connection to adapt such a large wheel to pass under bridges and other places where necessity requires that the conductor should be located close to the roof of the car.

Other features of my invention and the various advantages to be gained thereby will be pointed out hereinafter.

Referring to the drawings, Figures 1 and 2 are respectively plan and side views of my improved trolley. Fig. 3 is a view of the upper part thereof, showing the position of the contact-wheel when turned so as to allow for lateral variation in the position of the conductor. Fig. 4 is an end View of the trolleybase. I Fig. 5 is a section of a part of the base on the line 5 5 of Fig. 1. Fig. 6 is a side view of my trolley passing under one of my improved conductor connections. Figs. 7 and S are respectively side and plan views of the conductor connections. Figs. 9 and 1 0 are end views, respectively, of the exit and entrance thereof; Figs. 11 and 12 are sections respectively on the lines Y Y and X X.

Secured to the roof of the car is a longitu dinal track L,upon which a truck His adapted to roll. This arrangement allows me to place the base at any desired longitudinal position, so that contact may be made at or about the center of the car whatever the direction of travel. Vertically pivoted to this track is the turn-table G, upon which the parallel trolley-rods D and E are pivotally secured. The rotary movement of the base and the longitudinal movement'of the truck may be locked by the key J, as shown, at any suitable location.

The rod D is secured within the lever-socket D, which latter is horizontally pivoted between lugs G G on the top of the turn-table. From one end of D the tension-springs F F are secured to a horizontal projection K from Giwhich is another lug extending upward from G. In this manner- I may secure the requisite upward pressure at the end of rod D, and therefore between A and the conductor.

The rod E is horizontally pivoted to the lugs G G is a member to which D and E are pivotally secured and has a cylindrical opening therethrough to receive the swivel end of the yoke B, in which the contact-wheel A is rotatably secured. By pivotally securing the rods D and E in this manner 0 must always remain in the same position, so that the swivel end of B always remains horizontal. This contact-wheel I prefer to make of aluminium, so that it will notbe unduly heavy, and its sizeis preferably about four feet in diameter. By the use of such a wheel I am enabled to obtain an excellent contact at all times, and because of its comparatively slow rate of rotation the wheels and bearings have a greatly-increased life. Another advantage in the use of such a feature is that I do not need lateral. movement of the arm itself, as

I have the easier movement of the swiveled In Figs. 6 to 12, inclusive, I show the con ductor connections I provide for passing my large wheel under bridges and other places. This connection is substantially a single shield S, to which the conductor is secured at each end. It may be constructed of a number of pieces of sheet-iron, brass, or other suitable material, secured together in any desired manner.

A is the contact-wheel as it enters the shield. It is shown, as I prefer to have it,

turned at an angle of about forty-five degrees.

as it enters.

A is the Wheel as it is under the bridge, in a car-barn, or other similar locations. In this position the horn 0 becomes the contact portion of the device, as shown in Fig. 6.

A shows thewheel as itemerges from the shield at a preferred angle with the conductor of ninety degrees.

I desire to be understood as not limiting myself to the exact details herein set forth, as many modifications may be made in: my improved trolley and in the conductor connection described Without departingout'side the scope of my invention. a

What I claim, and desire to protect by Letters Patent, is-

1. Inan electric trolley device, the combi nation'of a base, arms mounted thereon about transverse pivots, and a contact-wheel car ried by said arms and'adapt'ed to follow lateral'variations of the con'd-uctor'by'itsown movement: about a horizontal axis.

2. Inan electric trolley device, the combination-of a rotatable base and means for normally preventing it from rotation, arms pivotedto said base, and a contact-Wheel-car-ried by the arm and adapted to follow the lateral variations of the conductor byits own movement about a horizontal axis.

3.. In an electric trolley-device, in combination, a base, parallel arms pivotally secured to said base, means for imparting upward pressure to the outerend of one of said arms, a member pivotally secured to the outer ends of each of said arms, a yoke horizontally sw-iveled'in said member, and a contact-Wheel carried by said yoke.

at. Ina trolley. device for electric vehicles, in combination, a longitudinal track carried by the vehicle, a truck movable along said track and carried thereby, a turn-table'carried by said truck, and connections from said truck to the contact portions of the devices. 5. In a trolley device for electric vehicles, in combination, a longitudinal track uponthe vehicle, a truck carried thereby, and movable therealong, a table revoluble upon said truck, and means for simultaneously locking the movement of the table and the truck.

6. An electric trolley device comprising, in combination, a pair of arms pivotally secured on a revoluble base, means for imparting upward pressure to the outer end of one of the said arms, a member pivotally secured to said arms in a horizontalposition, anda yoke S. A conductor connection adapted-forum at bridges &c. with trolley devices employ portion, sill) ing large wheelsadapted to makecontaet with a suspended conductor, having a horizontal-portion adapted'to be placed undertlie bridge and inclined portions at eaclreud thereof, connected to the conductor and adapted to turn the contact-wheel to a nearly 1 horizontalposition', substantially-as set-forth.

9 In an electric railway, the combination of a trolley device having a horizontally-mi eled contact-wheel and a born, as c, with a cond uctor connection adapted to turn the com tact-Wheel and-make contact-with the born,

In testimony whereof I have affixed my sig nature inpresenee of two Witnesses.
