VHITESTONE, NElV YORK.

TROLLEY.

SPECIFICATION forming part of Letters Patent No. 736,721, dated August 18, 1903.

Application filed May 28, 1903. Serial No. 159,071. (No model.)

To ctZZ whom, it may concern:

Beitknown thatl, EDWARD HALL, acitizen of the United States, residing at Whitestone, in the county of Queens and State of New York, have invented certain new and useful Improvements in Trolleys, of which the fol lowing is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a trolley for electric street or other railway cars to be used in connection with the so called overhead-wire system and which is simple and durable in construction and which will not allow the trolley-wheel to jump off the conductor-wire, but will retain the trolley-wheel and conductor-wire in operative connection at all times; and with this and other objects in view the invention consists in a device of the class specified, constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form apart, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which- Figure l is a side view of a trolley device constructed according to my invention and showing also a part of an overhead wire or conductor; Fig. 2, a similar View of the trolley device, but showing the parts in a different position; Fig. 3, a sectional View looking in the direction of the arrow as of Fig. 2, and Fig. it asection on the line 4 4 of Fig. 2.

1n the practice of my invention I providea yoke or fork a, having a socket 00 with which the usual trolley-arm b is connected, and the yoke or fork a is provided with two downwardly-directed arms a which are preferably at an angle of aboutforty-five degrees to the trolley-arm, but which may be at an acute angle, if desired. The arms a of the yoke or fork a are provided with longitudinal spaces w, in which are mounted journal-boxes c, and at the opposite sides of the spaces a are grooves a and the journal-boxes c are pro vided with side ribs or projections 0 which move in the grooves a and between the jourrial-boxes c and the bottom portions of the arms a are placed springs d. The longitu dinal spaces a in the arms a open at the top of said arms in order that the journal-boxes 0 maybe passed thereinto, and secured to the top portion of said arms are blocks 6, which hold the journal-boxes in place and prevent their being thrown out by the springs cl.

The trolley-wheel f is provided with a shaft f supported by the journal-boxes c, and said trolley-wheel is also preferably provided at each side with a short hub f and these hubs bear on the journal-boxes c, and by reason of this construction there is a slight space between the trolley and the separate side members a of the yoke or fork to.

Connected with the separateside members a of the yoke or fork a and at a predetermined distance rearwardly of the journalboxes 0, as shown at g, are yoke-shaped arms h, preferably composed of heavy wire or small rods, and the separate sides ]t2 of the yokeshaped arms h are connected with the parts a of the fork or yoke a at both sides thereof, as clearly shown in Fig. 3, and in order to accomplish this result the separate side portions h of the yoke-shaped arms h are bent to form rings or eyes If, through which the pivot pin or bolt 9 is passed, and each side portion h2 of each of the yoke-shaped arms h is also formed into a projecting finger h at each side of the side members a of the yoke or fork a, and these projecting fingers h are passed through keepers k at each side of the journal-boxes c. As thus constructed the arms h, which project backwardly and upwardly when the separate parts are in their normal position, as shown in Figs. 1 and 2, will rise and fall with the journal-boxes c, and these journal-boxes will rise and fall according to the pressure applied by thetr olleythe trolley-and wire conductor-j are frequently disconnected by reason of violent movements of the trolley-arm I), caused by the motion of the car, and this necessitates the readjustment of the trolley-wheel and the placing thereof in connection with the wire or conductor j; but by means of my improvement the wire conductorj is prevented from leaving the trolley-wheel, the arms h serving at all times to hold said wire or conductor in proper and operative position with relation to the trolley-wheel f. a

It will be understood, of course, that the trolley-arm b is connected with a car in the usual manner and is adapted to swing both in a horizontal and vertical direction, the vertical movement thereof being regulated by a spring; but these parts form no part of this invention, and therefore are not shown and described.

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

1. A trolley device, comprising a fork having downwardly-directed arms, verticallymovable and spring-supported journal-boxes mounted in said arms and by which the-trolley-wheel is supported, and yoke-shaped side arms pivoted to the fork rearwardly of the journal-boxes and extending upwardly and bac'kwardly, and the separate side members of which are provided at their pivotal supports with backwardly-directed fingers which pass through keepers secured to the journalboxes whereby said arms are given a vertical movement by the rise and fall of the journalboxes, substantially as shown and described.

2. A trolley device comprising a fork having downwardly-directed arms, verticallymovable and spring-supported journal-boxes mounted in said arms and in which the trolley-wheel is supported, and guard-arms pivoted to the side members of the fork and projecting upwardly and backwardly and provided at their pivotal supports with backwardly-directed members in operative connection with the journal-boxes whereby said guard-arms are raised and lowered by the movement of the journal-boxes, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 26th day of May, 1903.

EDWARD HALL.
