SPECIFICATION forming part of Letters Patent No. 780,620, dated January 24, 1905.

I Application filed September 17, 1904. Serial No. 224,882.

y following is a specification, reference being had therein to the accompanying drawings.

This invention, relates to new and useful improvements in thel construction of Aconducting trolley-wire finders for electric cars, by means of which trolley finders are expeditiously guided into position to contact with the overhead trolley-wire in such cases as when the trolley jumps out of contact with said wire.

The object of this invention is to construct a conductor-wire finder of a bifurcated form that will be cheaply manufactured and easily of the trolley-linder are capable of being` moved into nearly the vertical position, so that the free outwardly-flared ends of said arms or bifurcations will be readily caused to engage the-conducting-wire to direct the trolley into position to contact said wire. I attain these objects by vmeans of the trolley-wire finder illustrated in the accompanying drawings, in which similar numerals of reference designate like parts throughout the several views.

Figure l is a side elevational view of the forked end of a trolley-pole, showing the trolley end thereof contacting with the conducting-wire and the arms of the trolley-finder in their normal vor approximately horizontal position.` Fig. 2 is a plan view of the same, showing the spring in dotted lines, so that the trolley-finder, which is situated in the plane beneath the spring, may be shown in full lines; Fig. 3 is a View of the trolley similar to Fig. 1, but showing the trolley-under arms extending upwardly in position to engage the conducting-wire to guide the trolley to said wire. Fig. 4 is a developed view of the trolley-finder or fork, which shows the said trolley-finder fork formed in one integral piece and cut from a single sheet of metal.

Fig. 5 is a detail View of the said trolley-finder fork, showing said piece as represented in `Fig. 4 bent into form; and Fig. 6 is a detail perspective view of the retaining-spring of the trolley-wire finder.

The trolley-pole is designated by l, and on the top end of the same is secured the trolleycarrying fork 2. On the free end of said trolley-carrying fork 2 are formed the bosses 3, which are drilled to receive the bearing-bolt 4, upon which the trolley-pulley 5 is journaled.

The trolley-finder is composed of the outer bell-crank arms 7, the inner bell-crank arms 9, connected at their lower ends by the bend 8, and the upwardly-extending pull-down arm 11. which parts are preferablyformed in one integral piece cut from a single sheet of metal in the form illustrated in Fig. 4, in which 7 also denotes the outer projecting trolley-wirefinder arms; IO, the pivotal bores; 9, the rear bell-crank arms; 8, the central bend connect- -ing portion, and ll the upwardly-extending pull-down arm, which latter is formed to eX- tend at right angles with the upper edges of the bell-crank arms 9. The outer ends 12 of the arm 7 are flared outwardly, so as to the more readily engage the conducting or trolley wire when said arms are moved into vertical position. (See Fig. '5.) The trolleyfinder thus constructed has its pivotal portion of its arms pivoted on the axle-bolt so that said arms 7 and 9 are situated between thev hubs 3 of the trolley-fork 2 and the hubs 6 of the trolley-pulley 5 to be capable of being fully manipulated without contacting with either said trolley-pulley or the fork of the trolley-pole. The trolley-finder 'is yieldingly maintained in its normal position, as shown in Fig. l, bythe retaining-springs 13, which latter have their lower ends 14 secured by suitable rivets or screws yto the trolley-pole fork 2, and the said springs have their opposite ends provided with the notches 15 to engage the edges of the arms 7, and therebyA prevent the notched ends of said springs becoming disengaged from said arms. The trolley-rope 16 is secured to the top end of the upwardlyprojecting pull-down arm 1l. The object of constructing the said pull-down arm l1 as shown and described I will now proceed to describe. It is clear that were the end of the trolley-rope 16 attached directly to the trolley-finder at the bend 8 thereof then when the said trolley-rope 16 would be pulled to cause the ends 12 of the arms 7 to swing upwardly toward a vertical line the amount of swing thereby obtained would be insufficient to elevate the arms 7 sufficiently into a vertical position to properly engage the trolley or conducting wire, which condition is due to the position of the operator relatively to the end of the trolley-pole and the angularity of the trolley-rope 16 with the end of the trolleypole. In order to overcome this defect, I provide the upwardly-extending pull-down arm 11, to the top end 0f which the trolley-rope 16 is made fast, and thus the connecting-point of the said trolley-rope 16 at its top end being so elevated above the bend 8 of said trolley-finder the operator can readily manipulate the rope 16 to swing the trolley-wire-finder arms 7 into approximately vertical position, as shown in Fig. 3, and thereby cause the said arms 7 to arrive nearer to a perpendicular position relative to the conducting-wire 17 to more readily direct the trolley 5 into position to contact said conducting-wire 17.

Having thus fully described this my invention, what I claim as new and useful, and desire to cover by Letters Patent of the United States therefor, is-

1. In a trolley for electric cars, the combination with a trolley-pole having an upper forked end, a journal-bolt passing through said forked end, a trolley-pulley pivoted on said bolt and situated between the bifurcations of said forked end of said trolley-pole, a bifurcated trolley-wire finder having its side arms drilled to be pivoted on said bolt, a rear bendconnecting the rearwardly-projecting ends of said trolleywire finder and an upwardly-projecting arm secured to said rear bend.

2. In a trolley for electric ears, the combination with a trolley-pole having an upper forked end, a journal-bolt passing through said forked end, a trolley-pulley pivoted on said bolt and situated between the bifurcations of said forked end of said trolley-pole, a bifurcated trolley-finder constructed of a single piece of metal bent to form two parallel arms or bifurcations, both of which arms are drilled at their central portions to pivotally receive said iournal-bolt and to be situated on each side of said trolley and between the bifurcations of the forked end of said trolley-pole and an upwardly-extending pull-down arm on the bend of said trolley-finder.

3. In a trolley for electric cars, the combination with a trolley-pole having an upper forked end, a journal-bolt passing` through said forked end, a trolle T-pulley pivoted on said bolt and situated between the bifurcations of said forked end of said trolley-pole, a bifurcated trolley-finder constructed of a single piece of metal and each piece is divided to form forward finder-arms and rear bent parallel arms, the vertical angle of the forward arms being at an angle with the rear parallel connected arms or of a bell-crank form, said finder-arms drilled at their central portions to be pivotally mounted on said journal-bolt, an u p wardl y-extend in g pul l-down arm formed integral on the rear connecting-bend of said bell-crank trolley-finder and a yielding spring securedon said trolley-fork and having its free end bearing at or near the top free end of the said forked arms.
