TROLLEY FOR ELECTRIC LINES.

SPECIFICATION forming part of Letters Patent No. 733,496, dated July 14, 1903. Application filed March 5, 1903. Serial No. 146,406. (No model.)

To all whom it may concern.-

Be it known that I, KENNEDY LYONS, a citizen of the United States, residing at New Ru mley, in the county of Harrison and State of Ohio, have invented certain new and useful Improvements in Trolleys for Electric Lines, of which the following is a specification.

This invention relates to means for holding the trolley to and preventing its flying. olf from the line-wire.

The means devised for attaining the desired end consist of two springs firmly attached at one end to the members of the harp or trolley frame and having their opposite ends bent to extend over the edge of the trolley-wheel and normally hold the line-wire in the peripheral groove thereof, said ends being slightly downwardly converged toward their inner extremities to direct the line-wire into the space formed between them when fitting the trolley to the line and to retard the exit or escape of the line under conditions which usually edect a displacement of the trolley, but which will admit of the disengagement of the trolley upon application of suificient pulling force to the operating-cord.

For a full description of the invention and the merits thereof and also to acquirea knowledge of the details of construction of the means for efiecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a trolley embodying the invention. Fig. 2 is a section about on the line X X of Fig. 1. Fig. 3 is a detail perspective view of a spring-guard.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The trolley harp or frame lmay be of any type of construction and is applied to the trolley pole or arm in any accustomed way.

The trolley-wheel 2 is mounted upon an axle or pin supported at its ends in the sides or fork members of the harp. These parts may be of any structural design.

. The guards 3, constituting the vital feature of the invention, are secured at oneend to the sides of the trolley-harp and extend along the sides of the trolley-Wheel and have their opposite ends bent inward, as shown at 4, to extend across theedge of the wheel, so as to confine the line-wire and prevent displacement thereof under ordinary usage. The guards ,3 are preferably formed of spring metal, and the bent ends 4 are converged toward their inner terminals in a direction toward the center of wheel 2, which in practice may be designated as being in a downward direction. The extremities of the bent ends 4 are spaced apart to facilitate the passage of the line-wire between them. The bent ends 4 possess a spring action and yield independently of the body or main portion of the guard, thereby admitting of the line-wire readily passing between them when placing the trolley upon the line-wire. Any force tending to effect a casual displacement of the trolley from the line-wire will be counteracted by the bent ends 4 of the guards, which serve to hold the trolley in place upon the line-wire under usual conditions attending upon practical operation of the device. When the trolley tends to fly from the line wire, the latter will be engaged by one or the other of the bent ends 4 and directed into the angle formed between said ends and body of the guard and resist considerable displacing force, thereby holding the trolley in place. However, when it is required to remove the trolley from the line-wire the application of sufficient pulling force to the operating cord or line will overcome the retaining influence of the spring-guards and cause them to yield and permit escape of the linewire. It will thus be seen that a trolley embodying the invention may be fitted to and disengaged from the line-wire in the accustomed way, while at the same time it is prevented from casual displacement when acted upon by usual force or other cause commonly tending to cause the trolley to fly from or leave the line-Wire.

Having thus described the invention, what is claimed as new is 1. In a trolley for electric lines, and in combination with the frame and trolley-wheel, guards of spring metal secured at one end to the members of said frame and having their opposite end portions extended up along the sides of and across the edge of the trolleywheel, and having their terminal portions downwardly converged and adapted to yield inward and outward in the plane of the trolley-wheel and the extended end portions to move laterally, substantially as set forth.

2. In a trolley for electric lines, and in comtions to move laterally, substantially as specified.

In testimony whereof I atfix my signature in presence of two witnesses.
