TROLLEY MOUNT.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application'filedJune 2; 1913f Serial N6: 771,190;

alinement with the wire so that in turning corners, passing onto and off from side tracks, etc, the trolley will be perfectly free to follow all. changes in the alinement ofthe wire without lateral wearing pressure upon. either trolley or wire, thereby effecting a great saving in the cost of maintenance, and eliminating the danger of the trolley running off from the wire.

With these and other objects in view I have devised the novel structure which I will now describe, referring to the accompanying drawing forming a part of this specification and using reference characters to indicate the several parts.

Figure 1 is a side elevation of my novel trolley pole as in use; Fig. 2 a plan view corresponding therewith; Fig. 3 an inverted plan view; Fig. 4 a plan view of the crossed arms and carrying plate, the pivot bolt being in section and the pole and extension removed, and Figs. 5 and 6 are plan views corresponding with Fig. 2 illustrating changed positions of the parts corresponding with changesin the alinement of the wire.

10 denotes the pole, the upper end of which is bent to the horizontal plane and carries a hinge member 11.

12 denotes anextension of the pole which lies in the horizontal plane and carries at its inner end a hinge member 13 which is pivoted to the yoke by means of a vertically disposed bolt 14. The bolt extends below the hinge and has pivoted thereon crossed arms 15 which rest upon a carrying'plate '16 through which the bolt also passes,-the

parts being shown as retained in place by a nut 17. The crossed arms are shaped not unlike scissor members-and are shown as recessed into eachother like scissor members, the end walls of the recesses, indicated by 18, serving as stops to limit the opening move ment of the arms. Ropes 19 are attached to the inner ends of thearms, are passed downward through an opening20 in the carrying plate and are connected together as at 21 so that a single rope passes down to the car platform by which both arms and the pole manipulated. The carrying plate is provided with an upturned flange 22 provided with a notch 23 which receives the pole and thus holds the plate against movement independently of the pole. At the forward ends of the arms are upturned ends or lugs 24 which lie on opposite sides-of extension 12. At the forward end of the extension is a head 25.

2G denotes the trolley which is journaled in a yoke 27 having a shank 28 which extends through head and is free to oscillate therein. The shank is provided with a collar 29 which rests upon the head. Below the head and rigidly secured to the shank is a lever 30 which is adapted to engage either of the lugs 24 on the crossed ,arms. The portion of shank 28 which passes through the head of the lever is made Fangular to lock the lever against rotation on ithe shank and the parts are secured in place :by a nut 31 engaging the threaded lower end ;of the shank.

The operation will be readily understood from Figs. 5 and 6 in connection with Fig. 2. It will be noted that the shank of the trolley yoke is free to oscillate in the head on the extension and the extension itself is free to oscillate in the horizontal plane relatively to the pole. I thus provide for any possible variation in the position of the wire and changes in alinement as in turning corners. The result is that the flanges of the trolley will automatically retain their parallelism with the axis of the wire and thus avoid any tendency of the trolley to run off from the wire in turning corners or takingside tracks upon the flanges of the trolley is practically jeliminated. Should the trolley run off the- ;wire when the parts are in a position approximating the position shown in either Fig. 5 or Fig: 6, a pull upon the rope will icause the lugupon one of the crossed arms to engage the lever, the effect of which will be to swing the lever and trolley into alinement with the extension and the extension into the vertical plane of the pole, as in Fig. 2. As the pull of the rope is now upon the pole, the pole may be manipulated thereby and furthermore wear upon the wire and and the trolley reengaged with the wire in precisely the same manner as with the poles 111 (20111111011 use.

Having thus described my invention 1 claim:

1. The combination with a trolley pole and an extension pivoted thereto, 01' a trolley yoke pivotally mounted on the extension, a. rope and means adapted to be operated by the rope for swinging the yoke and the extension into the vertical plane of the pole.

2. The combination with a trolley pole and an extension pivoted thereto, of a trolley yoke pivotally mounted on the extension, a lever rigidly secured to the shank of the yoke and pivoted crossed arms having lugs engaged by the lever and adapted to engage the extension, whereby the yoke and the extension may be swung into the vertical plane of the pole.

3. The combination with a trolley pole having its upper end bent to the horizontal plane and an extension pivoted thereto and adapted to swing in the horizontal plane, of a trolley yoke pivotally mounted on the extension and means for swinging the yoke and the extension into alinement with the horizontal portion of the pole.

4. The combination with a trolley pole and an extension pivoted thereto, of a trolley yoke pivotally mounted on the extension, a lever rigidly secured to the shank of the yoke, pivoted crossed arms having lugs at their outer ends adapted to be engaged by the lever and to engage the extension, and ropes connected to the inner ends of the arms whereby the yoke and extension may be swung into the vertical plane of the pole.

5. The combination with a trolley pole and an extension pivoted thereto and having a head atits outer end, of a trolley yoke having a shank pivoted in the head, a lever rigidly secured to the shank, pivoted crossed arms having lugs at their outer ends adapted to be engaged by the lever and to engage the extension, and ropes connected to the inner ends of the arms, for the purpose set forth.

6. The combination with a trolley pole having its end bent to the horizontal plane and provided with a hinge member, an extension having a corresponding hinge member, a pair of crossed arms having lugs at their outer ends, a carrying plate on which said arms rest and which is provided with an opening and an upturned flange having a notch which receives the pole, of a pivot bolt passing through the hinge members, the arms and the carrying plate, a lever rigidly secured to the shank of the yoke and engaging the lugs on the arms and ropes connected to the rear ends of the arms and passing through the opening in the carrying plate, whereby the yoke and the extension may be swung into alinement with the pole and the pole as a' whole may be manipulated.

7. The combination with a trolley pole, an extension pivoted thereto, a trolley yoke having a shank pivoted in the outer end of the extension and a lever rigidly secured to the shank, of crossed arms pivoted concentrically with the extension and having lugs engaged by the lever.
