SPECIFICATION forming part of Letters :Patent No. 527,601, dated october 1e, 1894.

Appncaio'uea rtm1] 16, 1894.' serial No. 503,321. (No man.)

To all whom, it may concern.-

Beit known that I, OLIVER B. FINN, a citizen of the United States, residing in/the city and county of Philadelphia, Stateof Pennsylvania, have invented a new and useful Improvement in Electric Railways, which improvement is vfully set forth inthe following specification and accompanying drawings.

My invention consists of an electric railway formed of a shoe which is connected with a car, so as to travel therewith, a movable stem with a roller which may be engaged by saId shoe, an arm with which said stem may contact, and a feed wire carrying said arm, whereby a circuit may be formed and communicated from said'wire tothe motor of the car, as will be hereinafter more fully described.

It also consists of details Vof construction, as will be hereinafter set forth.

Figure 1l represents a partial transverse Vertical section and partial side elevation of an electric railway embodying my invention. Flg. 2 represents a similar view of a portion, showing certain parts in different position from that in Fig. 1. Fig. 3 represents a longitudinal horizontal section on line as, oo, Fig. 1. Fig.- 4 represents a vertical section on line' y, y, Fig. 1. Fig. 5 represents'a face view of an insulating' block that is employed for the roller stem. Fig. 6 representsa top view on a reduced scale.' Fig. 7 represents a perspective View of the insulation Fig.' 5. Fig. 8 represents a side elevation of the lower portion of the hanger and adjacent parts. Fig. 9 represents a vertical section of a portion of the conduit as coupled with a tube or pipe on the side thereof, showing also the feed wire passing through the same. Figs. 10 and 11 represent side elevations of the upper portion of the hanger. Fig. 12repres'ents a horizontal section on line z, z, Fig. 11, the scale of Figs. lO, 11, and 12 being different from those in the other figures.

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

Referring to drawings: A designates a car rail, at the side of which is a conduit B, in the top wall whereof is, a slot C. The door of the said conduit B is formed of brackets B, located at intervals, the spaces between which permitting water or other foreign matter to fall into the gutter below the same, the

latter beingad apted to'receive the water-that 'may enterthe conduit through the slot C,

said gutter having a draining or discharging pipe which leads to a seweror other suitable outlet.' At the side'of said conduit'Bisv' a box D, in which is supportedthe feed WireE to which is attached the arm EQ'Whereby when the latter is forced back, the wire is subjected to torsion, and when thearm is afterward released said spring restores the arm to its normal position. The lower end of thearmE has a hook E2 thereon, the same being adapted to be engaged by the reduced endE3 of the stem G, so as to increase the contact surface of the stem with said arm, and also increase 'pressure at point of contact since the tendency of the hook E2 is to rise when .the Ystem G is forcedin against it.

Interposed between the conduitB and box D is a wall F, in which is guided the supporting-stem G of a roller H, said stem being in horizontal position, and the roller having a vertical axis.

. The' box D has its-sides coupled as at D with the lengths of pipe D', and hung thereon so'that said .box may be rotated, and thereby raisedfrom the' position shown in Fig. 1, to

ythat shown in Fig. 2, whereby the roller H and adjacent parts are accessible for repairs or other purposes requiring the same. In

.this case, a plug shown in dotted lines Fig. 2,

is inserted between the bearings of the roller H and the'insulation S, so that the roller stem is prevented from being placed in contact with the live wire. Bearing against said stem\ Gis av spring G', which is secured within the vbox D, and serves to return said stem to its normal position. Opposite to the roller is the shoe J, which latter is yieldingly supported on the hanger K, and has pressing against it the buer-springs L, which are suitably connected with said hanger and shoe, thus permitting the vibration of the shoe, due to the motion of the car, it being noticed that the hanger is properlyV secured to the car, and moves through the slot C, it being also eviv'dent that the car will be provided with two 'lOO hangers, each connected with the shoe at opposite places.

The flaring ends ofthe shoe J, and the porp tion of the face adjacent thereto are made of or covered with insulating material, so as to prevent any current from flowing until perfeet contact has been established, when the roller iirst comes on the shoe, and to discontinue the flow of electricity before the contact is broken at the rear of the shoe, whereby sparking is prevented at the contact of the roller and roller stem as said roller is passed by.

The hanger has its lower portion K connected with the main portion thereof, by means of pivot K2, whereby said lower portion may vibrate on said pivot and turn when the shoe and hanger are being removed.v The hanger has a grooved block K4 connected with the back thereof, said block being freely embraced by a sleeve K5 which is attached to the supplemental hanger K6. Interposed between the block K4 and the supplemental hanger K6 is a sliding filling piece K which has inclined shoulders aabove its outer end, and stops b and c on its ends. A bolt K7 passes through said block K4, and the slot K3 of the hanger, and also through a link KS, the upper ends of the link and hanger having limbs thereon to which are attached respectively the ropes or rodsK9 and K10, whereby when the rope K9 is drawn, the hanger with its connected parts may be raised, and when said rope K10 is drawn, the hanger receives angular motion, and so is withdrawn from the conduit, the latter having doors A at intervals, to effect such removal. f See Fig. 6. When the hanger rises, the block K4 clears the sleeve K5, and so may receive the aforesaid angular or lateral motion but when the hanger is lowered, the block engages with t said sleeve K5 and is locked by the same with the supplemental hanger K6, which latter is fixed to a suitable part of a car, and thus the hanger proper is held rigid during operation.

When the'hanger K is raised, and the link KB lifts the bolt K7, the latter raises the sliding piece KX, so that the shoulder a enters the sleeve K5 and thus holds said piece KX fairly rigid in said sleeve. The upward motion of said piece is limited by the stop b, and the downward motion thereof is limited by the stop c, said stops being adapted to abut respectively against the lower and upper ends of the sleeve. When lateral motion is imparted to the hanger in the withdrawal of the same from the conduit, the block K4 turns on the piece KX, the bolt K7 constituting the axis of said block.

Rising from the shoe J is a guide J2, the same playing freely in the slot C.

A roller M is journaled in a recess in the upper face of the horizontal arm or base N of the hanger K, and bears against the lower side of the shoe J, whereby said shoe may be nicely sustained in its vibrations.

On the hanger K is an insulated joint P, whereby the current is prevented from leaking to that portion of the hanger that may come in contact with the sides of the slot. Above said joint is a detlector or shed Q for directing water from the shoe, roller and adjacent parts.

R designates an insulated wire, which is connected with the hanger K, and forms the electric communication of the motor of the car and shoe.

In the wall F of the conduit and box are insulating blocks S for the stem G of the roller H, said blocks being readily inserted in an opening in said wall and retained in position by the key T, said opening being of such dimensions that the roller and stem thereof maybe readily placed in position and removed therefrom through said opening.

The ends of the shoe are flaring as at J',

so that the same will contact with orstrike t the roller without abruptness.

It will be seen that when the shoe reaches the roller H,it presses the same, whereby the stem G is forced into contact with the arm E', and a circuit is accordingly formed, the current thus being transmitted through the feed wire, the arm, the stem and the roller, to the shoe J, and from thence through the wireR to the motor of the car, the eect of which is evident. When the shoe leaves the roller, the latter is returned to its normal position owing to the action of the spring G', the stem G being relieved of contact of the arm E and thus the circuit is broken, it being however observed, that when the roller of the series employed, is about to leave the shoe, the

roller ahead is about to contact with the forward end of the shoe, and thus there is always a roller on the shoe.

Insulation is applied to parts wherever required.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is` t 1. In an electric railway, a conduit, a box with an opening in its wall,a sliding stem in said opening having a roller thereon, an insulated wire in said box having an arm rigidly connected therewith, said arm having IOO IIO
