My invention relates to clectricrcilways of that class iii which the current? is delivered.

to the electric motors on the car from overhead conductors supplied with current fro'hra dynamo or other generator of electricity at a central slntion or from several stations along the. line.

My improvements nre'directed tothe sn'p- .zo porting and condncting'connections between trolley with the snpply-wi're from beneath,

car, to ontonmtimlly retnrn'tbe'trolleyitoits' either side ol'the center, and to provide means toavoid too great lateral play ofthe trolley relatively to thewire, soasto avoid the escape of the trolley from beneath the wire and its elevation above it-fronieither side,- to

compensate for the vibrations-or jolts of thenormal central position beneath the wire not-' withstanding lateral vihrat-imi of the trolley to for readily shifting the trolley or conductingconnections when the end of {the route is reached and'from within the car, so. that the trolley may be readily adjnsted'to trail-under and in contact with the condncting-wire ac.- cording to the d irgciionof trnvel'of'the car and without necessitatingexternal 'shiftingor' reversing appliances fort-ho one; or its ,snp-

The bearings 13 B" B of the trolley may have oil-holes for oiling, and one of the end bearings or castings, B, may have a plug, b, to admit the injection of a small quantity of oil to the interior of the-trolley cylinder or drum to be tossed about and lubricate the parts and bearings. A

The opposite tapered or cone ends 13 B of the trolley B are each fitted with a spiral flange, 1), leading to the V-shaped central portion, B, of the drum, and are for the purpose of directing the wire to the center of the drum when the trolley dips and springs back out of true or the center line, as is apt to be the case many times during a trip of the car, owing to unevenness of the track and running of the car, 810. The wire thus caught on the cone-surface runs on the parallel flange I) of the angle-flange b, and thus prevents wear of the body of the trolley, while the upright part b of said angle-flange, being spirally arranged, directs the wire to its proper central V-shaped working-surface of the drum formed by the section B thereof. This central V-shaped section, B, also insures smooth running of the trolley. Said central section, B has two annular curved or rounded bosses or ribs, 1) I), cut away at the terminus of the spiral flange, so as to offer no obstruction to guiding the trolley centrally upon the wire, and these bosses also serve to readily shift the wire off the trolley or drum in turning out or leaving the main wire or in being switched off onto a switch-wire, the trolley always followingthe car.

As most ofthe wear on the trolley or drum is on the central section, B I fit it with a supplemental wearingsurface consisting of sec tions of preferably screw attached copper plates, as clearly shown in Figs. 6 and 7, so that when worn they may be readily replaced, and as provision is made by the spiral flange for taking the wear off the taper part of the drum or trolley, and as it may be readily replaced, I have provided a trolley which will last indefinitely and not need to be soon thrown away from wear of the wire, as was the case heretofore.

In Fig. 7 I show a modification of the angleflange Z), in that it is riveted by its parallel flange b permanently to the cylinder, while it has a readily-detachable wearing-flange for the wire secured thereto, so as to enable it to be readily removed and a new wearing surface substituted, as required.

In operation, with the parts properly adjusted, travel is had from one end of the line to the other without shifting of the trolley or any attention on the part of the driver or conductor of the car. When the terminus is the connections before described, and the return journey may be commenced.

In turning out, as with single-track lines, the trolley.

having but slight play, follows the car, and

the main wire is readily shed or shifted off the trolley by the curved boss I)", and the new or turn-out wire as readily and effectually guided into the groove of the trolley. The

same remarks apply to switching, and several switch-lines as well as a turn-0ut have been illustrated by the diagram Fig. 8 of the drawings.

I claim as my invention- 1. The combination, with a trolley bearing upward against a conducting wire and its supporting and carrying connection on top of the car, of a shifting or reversing operating mechanism therefor fitted within the car-roof, substantially as described.

2. The co'mbination,with atrolley adapted to bear upward against a conducting wire and its supporting and carrying connection on top of the car, of a sleeve to shift said connection from the inside of the car and fitted with an operating-handle and locking device, substantially as described.

3. The combination of the trolley rod, its pivoted supporting lever, a dippingshaft, and gearing between said shaft and lever, whereby the trolley-rod may be dipped or inclined, as desired.

4. The combination of the trolley-rod, the bell-crank lever to which it is pivoted, the returning-spring between said rod and lever, a dippingshaft geared with said lever, and a handle to operate said shaft, whereby the relation of said rod to the conducting-wire may be determined by said dipping-shaft,while the spring maintains yielding contact.

5. The combination of the trolley rod, its pivoted supporting-lever, the turning sleeve upon which said lever is pivoted so as to be adjusted thereon, the handle to turn said sleeve, a dipping-shaft passing through said sleeve, gearing between said shaft and said pivoted lever, and a handle for said shaft, whereby the trolley-rod may be dipped or inclined by the dipping-shaft and the apparatus reversed by the said turning sleeve, substantially as described.

6. The combination of the conducting-wire, the trolley, and the turning sleeve which supports and carries the trolley-rod and its connections,with a fixed notched locking-plate, and a IIO locking device between said sleeve and plate,

substantially as described.

7. The combination, with the supporting lever and the trolley rod or standard pivoted thereon, of side guides fixed to said trolleyrod and preventing lateral motion of said rod upon said lever, substantially as described.

8. The trolley fitted with a spiral flange upon its cone end leading to the center of the trolley and with a portion thereof substantially parallel with the surface of the trolley to take the wear of the wire, substantially as 11. The trolley having a depression or groove for the conductingwvire to run in, and described. at each side thereof a curved or rounded an- 9.
