GEORGE WV. PERRY, OF PEORIA, ILLINOIS.

TROLLEY.

SPECIFICATION forming part of Letters Patent No. 652,039, dated June 19, 1900.

Application filed February 6, 1900. Serial No. 4,290. (No model.)

T all whowt it may concern.-

Be it known that I GEORGE W. PERRY, a citizen of the United States,residin g at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Trolleys; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in trolleys by means of which many of the objectionable features attendant upon the use of the ordinary trolley and wheel are overcome without cumbering the mechanism and without adding materially to the cost of the usual appliances.

The object of my invention is to provide constructive means in connection with the trolley appliances that will serve as a guide and an aid in the adjustment of the trolleywheel in contact with the wire and when so adjusted the same means serving to prevent clislodgment of the trolley from the wire, and incidentally the providing of a guard-wheel for contact with crossing wires along a trolley system.

My invention consists in the formation of the trolley-wheel support with vertical extensions from the body thereof in pairsone on each side of the trolley-wheeland carrying between the members of each pair a small roller or smooth -surfaced wheel journaled therein. The main function of such projections is served by those next adjacent to the trolley-wheel, which extend close alongside of the edges thereof and somewhat beyond the same and are curved over the edges of the trolley-wheel, forming a rib on each projection, which approach each other, leaving just I space enough between and just above the trolley-wheel to permit the entrance of the trolley wire, the upper edges of the projections being tapered toward the rib formation and leading to the opening over the trolleywheel, which tapering faces serve to aid in ing frame formed with my devices and made a part thereof. Fig. 2 is a side elevation of the device. Fig. 3 shows side and front views, respectively, of guard-lugs, showing the detailed formation thereof.

In carrying out my invention I have sought to provide an improved and more efficient trolley structure without adding to the cost, and for that reason I purpose to narrow the trolley-wheel down to just sufficient thickness to carry the wire and to dispense with the usual very much extended flanges and to provide a simple and shallow concaved bearing for the wire. By dispensing with the deep flanges, which are in practice so destructive to the Wire on account of frequent contact therewith, I protect the trolley-wire system to a great extent. Also by providing small rollers at the head of the trolley-wheel and on either side thereof I am able to pass crossing wires with great ease and with little attendant jar, as the small rollers or wheels when striking the wires turn readily and do not catch,as is usual with the ordinary trolley appliances, and, furthermore, the small rollers or wheels greatly facilitate in traveling curves that lead from a continuous line, as the rollers pass readily from the straight line-wire to the curved trolley-wire.

In the drawings, A is a ferrule projectio from the trolley-frame B, which is purposed to connect with the trolley-pole. In the trolley-frame B is journaled the trolley-wheel O.

D D are upwardly-projecting fingers bearing close up alongside the trolley-Wheel and extending beyond it a short distance, and as they pass beyond the outer edge of the trolley-wheel they are curved inwardly, forming the ribs a a, which approach each other as they arch over the trolley-wheel, leaving only a small open space between. The upper edges of the fingers are tapered inwardly, as shown in the drawings, and particularly in Fig. 1. The fingers D D, thus projected at the sides of the trolley-wheel and arching over it, serve to prevent dislodgment of the trolley-wire, and the tapered upper edges of the fingers serve to guide the wire to its seat upon the trolley-wheel. E E are also fingers projected in the same line and parallel with fingers D D and a short distance therefrom and serve, in conjunction with fingers D D, as a sufficient size to clear the upper edge of the fingers D D and serve to present a freelyturning contact-surface adapted to carry the trolley clear of obstructions, relieving it from any dragging or entangling contacts and serving greatly to aid in the smoothness of the running of the trolley and in the protection of the trolley-wire system.

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

1. In a trolley-Wheel, the combination with a frame structure supporting the trolley-wheel, of projecting fingers bearing close alongside of the edges of the trolley-Wheel and extending a short distance beyond the same provided with inwardly-bearing rib projections and tapered upper faces and corresponding fingers adjacent to and parallel therewith, and autifriction-whcels journaled between the fingers, substantially as described and shown.

2. In a trolley, the combination with a frame structure carrying a trolley-wheel and provided With a ferrule extension adapted to connect with the trolley-pole, of integral fingersprojecting from the axis of the trolleywheel and bearing close alongside thereof and a short distance beyond the same provided with inwardly-extendin g ribs and tapered u pper faces and antifriction-wheels, suit-ably supported in the framework and the circumferences thereof bearing a short distance beyond the ends of the fingers, substantiallyas and for the purpose described.

3. In a trolley, the combination with a frame structure supporting a trolley-wheel and provided with a ferrule extension adapted to connect with the trolley-pole, of integrally-connected fingers bearing close alongside of the trolley-wheel and provided With inwardly-projecting ribs and inwardly-inclined upper faces, and a corresponding pair of fingers a short distance therefrom and in parallelrelation therewith forming a pair of fingers on each side of the trolley-wheel and antifriction-whee1s journaled between each pair of fingers, the peripheries thereof bearing a short distance from the outer ends of the fingers, substantiallyas specified.

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

, GEORGE WV. PERRY.
