HARRISON OGBORN, OF INDIANAPOLIS, INDIANA, ASSIGNOR TO HIMSELF, CHARLES M. ROCK, CHARLES W. BRIDGES, ROBERT R. RUMBARGER, AND WILLIAM H. OGBORN, OF SAME PLACE.

TROLLEY-FINDER.

SPECIFICATION forming part of Letters Patent No. 564,638, dated July 28, 1896.

Application filed January 13, 1896. Serial No. 575,283. (No model.)

To all whom it may concern:

Be it known that I, HARRISON OGBORN, a citizen of the United States of America, residin g in the city of Indianapolis, county of Marion, State of Indiana, have invented anew and useful Improvement in Trolley-Finders Used on Overhead Electric Car Lines, which improvement is fully set forth in the following specification, drawings, and claims.

My invention consists in providing a trolley-Wheel and trolley-pole with an independent adjustable bar C, attached thereto, and so constructed that should said wheel be laterally displaced or disconnected from its place in contact with the electric conducting-wire, and forced upward above the conducting-wire by the springs at the base of the trolley-rod, it may be brought into contact with the same by drawing on the trolley-rope and swinging the guide rod against the wire, and then by releasing the tension on the trolley-rope the trolley-wheel will be instantly guided by the guide-rod to its place on electric wire V.

Figure 1 is a side elevation of myinvention. Fig. 2 is a side elevation showing the deviceholding receptacle in section. Fig. 3 is a top or plan view. Fig. 4 is a fragmentary section of the spring-holding receptacle in section on enlarged scale.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A indicates a trolley-wheel, B the trolley-pole thereof, both in general respects of the usual construction.

C designates a guiding-rod that is projected beyond the pulley by the trolley-rope D whenever it is drawn upon with suflicient force to draw the trolley-wheel down below the conductor-wire. On the lower end of rod C is permanently fastened a round lug E, of a size to loosely fit and freely move up and down in case E, which contains the rod C, spiral spring G, and rope D. There are two holes in lug E, at about equal distances from its center, one for the insertion of rope D and the other for the insertion of rod C. Rope D has a knot tied in the end on the under side of lug E to hold it in position.

H H are pins in case F to stop spring G.

Case F is held in position at the bottom by castings K K, which are fastened to the case F and trolley-rope B by bolts M M. These cast in gs have partly-open bottoms to allow water to pass out at the bottom of the case should it enter, and yet with enough bottom to support the round lug E on the rod C, which in turn supports the spiral spring G, that pushes the rod down in the case F when the draft on the rope is released. At the top of trolley-pole B and case F there are two castings N N, by means of which the case F and accompanying devices are attached to the trolley-pole B. These castings are open at their lower ends, as shown, while in their upper part is formed an oil-cup O by the flanges P P and conical top R to be filled with oil-absorbing packing. The flanges P P and conical top R R have holes in them to permit the rod C to pass up and down through them. There is also an opening in one side of these castings having flanges T T and in the side of case F at the top to permit of the insertion of pulley S, held in position by pin U. The

* trolley-rope D passes freely over pulley S and attaches at the lower end of the rod C to lug E by passing through the same and being secured thereto by a knot on the end of the cord or otherwise.

The operation is as follows: The trolleywheel B, when in normal operative position, runs-under and in contact with the conductorwire V, as usual. Should the trolley-wheel A jump the wire V or be otherwise displaced, the trolley-pole B and trolley-wheel A will spring forward and upward and project the trolleywheel above the conductor wire. When the operator takes hold of the trolley-rope to draw the pole and pulley down, the rope will first draw on the lug to which it is attached and by which the rod C is instantly projected upward and outward close to and in the rear of the center of the trolley-wheel. Then the trolley-wheel being further drawn down by means of the trolley-rope D, until it is below the electric conducting-wire,the pole is swung toward the wire until the rod C comes in con tact with it, by which the pulley is guided to its proper place, in contact with the electric wire, as shown in Fig. 2. When the draft on the rope is slackened, the rod C is instantly withdrawn out of the way into the case F by the force of gravity and the spiral spring G in case F, as shown in Fig. 1.

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

1. The-combination with a trolley, and trolley-arm, of an electric car, of a rod 0, supported by a trolley-arm in the plane of the trolley-groove, and located immediately behind trolley-wheel A, with the upper end of rod 0, just below the bottom of the groove, at the top of wheel A, said rod being incased in tube F, rope D, passing downward through case or tube F, and attached to lug E, at the 7 HARRISON OGBORN. \Vitnesses:
