TROLLEY FOR su -:ormo CARS.

srncrrrcarxon forming part of Letters Patent no. 591,oe2, dated October 5, 1897.

Application filed October 2,1 89 6- To all whom it may concern:

Be it known that 1, WILLIAM L. HARVIE, a citizen of the United States, residing at Newton, in the county of MiddleseX and State of Massachusetts, have invented certain new and useful Improvements in Trolleys for Electric Cars 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in trolleys for electric cars and it has for its objects, among others, to provide a simple and cheap attachment to a trolley whereby the wire can be more easily found and engaged by the trolley and when once engaged therewith it is almost impossible to lose the same or for the trolley to become disengaged therefrom. I provide the trolley with hinged portions upon each of which is carried a revoluble pulley or wheel, the hinged portions being urged outward below their pivots or hinges, so as to throw the upper ends inward toward each other, the said hinged portions being drawn down against the outer faces of the trolley-fork by the trolley-line which is connected therewith. The guard is under the control of the conductor or other person on the car, and can be quickly engaged with the wire.

Otherobjects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically define by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the let-. ters of reference marked thereon, form a part of this specification, and in which-.

Figure 1 is a side elevation showing my improvement. Fig. 2 is a face view with the grip ready to grasp the wire. Fig. 3 is a similar view with the grip engaged with thewire. Fig. 4. is a vertical section of the same.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the trolley-pole, B the fork, and O the trolley-wheel, mounted on an axle supported in the fork, as shown.

D are arms or plates one upon each side of the fork and hinged at their upper ends to Serial No. 607,678. (No model.)

the upper ends of the fork, as seen at (I, so as to fold down against the outer faces of the fork, and to the lower ends of these arms or plates are connected in any suitable manner the cords or Wires E, which pass through suitable guides or on the fork and to which is con neoted the end of the trolley-line G.

H are grips in the form of wheels mounted on axles 11, supported in the plates or arms D, as shown, and these wheels have their inner edges slightly concaved, as seen at 0, so that when the grips are thrown into their operative position these concaved edges will form, with the groove in the trolley, nearly a circle, as seen in Fig. 0.

I are springs arranged between the outer trolley-wire is pulled upon, which will compress the springs as the arms or plates are pulled toward the sides of the fork and the upper ends of the grips are opened, as shown in Fig. 2, making an extended surface to aid in more easily finding the trolley-line wire, and then the wire is released, when the springs will force the arms outward and the grips together, so that they grasp the wire and form with the trolley-wheel almost a complete circle from which the wire cannot easily escape. The springs keep the upper ends of the grips together.

Upon the arms upon which the rotatable trolley-wheels are mounted I provide a check X to prevent the arms from flying outward too far when the trolley is jumping a joint in the trolley-wire. This may be provided in various waysfor instance, by simply making a knot in the trolley-line just under where it goes through the pulley or eye under the trolley. It will be understood that this trolley-fixture will do away with all trouble 011 account of the accumulation of ice on the wire in winter, as said ice will be removed by the means hereinbefore described.

What is claimed as new is- 1. The combination with the fork and the trolley-wheel mounted therein, of plates, one upon. each side of the fork andhinged at their upper ends to the upper ends of said fork, cords connected to the lower ends of said plates, and grips rotatably mounted on said plates and extended beyond the upper ends thereof, substantially as described.

2. The combination with the fork and the trolley-wheel mounted therein, of plates, one upon each side of the fork and hinged at their upper ends to the upper ends of said fork, cords connected to the lower ends of said plates, and grips rotatably mounted on said plates and extended beyond the upper ends thereof, and-springs arranged between the outer faces of the fork and the inner faces of said plates, substantially as described.

3. The combination with the fork and the trolley-wheel mounted therein, of plates, one upon each side of the fork and hinged at their thereof, springs arranged between the outer faces of the fork and the inner faces of said plates, and guides on the outer faces of the fork through which said cords pass, substantially as described.

' 4. The combination with the fork and the trolley-wheel mounted therein, of plates, one upon each side of the fork and hinged at their upper ends to the upper ends of said fork, cords connected to the lower ends of said plates and grips rotatably mounted on said plates and extended beyond the upper ends thereof, the journals of said grip-wheels be ing disposed at right angles to the plates, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

upper ends to the upper ends of said fork, cords connected to the lower ends of said plates, and grips rotatably mounted on said 3 plates and extended beyond the upper ends WILLIAM L. HARVIE. WVitnesses:
