TROLLEY-GUIDE. f

SPECIFICATION forming part of Letters Patent No, 781,681, dated March 14, 1905. Application filed December 21, 1904. Serial No. 237,845.

To ar/Z 11/71/0722, it may concern:

Be it known that L'JoHN F. J AMESON, a citizen of the United States, residing at Plimpton, in the county of Holmes and State of Ohio, have invented a new and useful Trolley-Guide, of which the following is a specification.

In overhead electric-railway systems considerable difiicultv is experienced in preventing the trolley from jumping from the trolley-wire or conductor when rounding curves, due to the lateral pressure upon a trolley, and the same difiiculty is met with in crossing a railway-track or other track, Where the shaking and jarring movements of the car cause the trolley-pole to oscillatelaterally, and thereby displace the trolley-wheel from the wire.

The object of the present invention is to overcome the objections aforementioned in a simple and effective manner and to embody the invention in the nature of a guide for trolley-wheels which is complete in itself and capable of being erected in the path of trolleywheels at curves and railway crossings to maintain the trolley-wheel in proper contact with the trolley-wire or conductor, so as to prevent displacement thereof by lateral strains upon curves and by the jarring and shaking movements of cars when passing a railway crossing.

\Yith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a perspective view illustrating an embodiment of the present invention supported directly upon a trolley wire. Fig. 2 is a cross-sectional view thereof. Fig. 3 is a plan view showing the device used upon a curve. Figs.

'4 and 5 are detail sectional views showing preferred methods of supporting the guide independently of the trolley-wire.

l l i r Like characters of reference designate corresponding parts in each and every figure of the drawings.

The present device has been arranged for city and inter-urban use, the general construction of the guide being the same wherever located, and it is also constructed to be supported from a single row of trolley-poles in inter-urban use, between two rows of poles or other supports, and also directly upon a trolley-wire without extraneous supporting means when it is necessary to locate the guide between the usual trolley-poles.

The present guide includes a pair of substantially parallel rails or track members 1, provided at their lower edges with inwardlydirected substantially horizontal flanges 2, from which it will be understood that each rail is in the nature of an angle-bar of substantially L shape in cross-section. At suitable intervals corresponding standards or hangers 3 rise from the outer sides of the rail members, with their upper ends connected by the individual cross-bars at, there being longitudinal frame-bars 5 connecting the tops of the standards or hangers at each side of the device. As best illustrated in Fig. 1 of the drawings, it will be noted that the ends of the rails are bowed downwardly, so as to insure an easy entrance of the trolley into the guide. It will of course be understood that the space between the tracks or rails of the guide is entirely open and unobstructed by the free passage of the trolley-wheel therethrough. The general features of the guide are always substantially the same as thus far described without regard to the location thereof; but the manner of supporting the guide of course differs slightly according to its location.

\Vhen it is necessary to locate the guide between a pair of trolley-poles and it is not desirable to erect a supplemental support for the guide, it is proposed to mount the latter directly upon the trolley-wire, as shown in Figs. 1 and 2 of the drawings, wherein 6 designates an ordinary trolley-wire or conductor, upon which the present form of guide is supported by means of downwardly-tapered seats 7, which hang from the respective cross-bars 4, with their lower ends recessed or to receive the trolley-wire, upon which the seats rest, and thereby support the guide.

In interurbau use, as indicated in Fig. 5, wherein the trolley-wire 6 is supported upon the usual arm 8, extending outwardly from the trolley-pole 9 and supported at its outer end by a brace 10, inclined downwardly from the pole, the hanger-fran'ie of the guide is hung from the arm 8, to which it is secured, as at 11, in any suitable manner, with the trolley-wire located midway above the interval between the rails 1 and 2-.

\Yhen the trolley-wire is supported between two series of poles 12, as in Fig. t, the guide is hung from the cross bar or member 13, which extends between adjacent poles and to which the trolley-wire is connected, the guide of course following the direction of the trolley-wire, whereby it may be used upon curves, as shown in Fig. 3, as well as upon straight portions of the trolley-wire.

Any ordinary or preferred form of trolley will cooperate with the present guide, as clearly indicated in Figs. 1 and 2, wherein 14 designates a trolley pole or arm having the usual harp 15, with an ordinary trolley-wheel 16 supported within the harp and capable of traveling against the under side of the trolley-wire in the usual manner. In order that the trolley may engage the present guide, guide-rollers 17 are mounted upon opposite sides of the harp upon extended portions of the spindle or axle of the trolley-wheel, the flange 2 of the guide-rails 1 being spaced to recei e the guide-rollers upon the upper sides of said flanges, the upstanding portions of the rails ODOIiIiLIDg to prevent lateral displacement of the guide-rollers "from the track, and thereby to retain the trolley-wheel in proper engagement with the wire so long as the guide-rollers remain upon the guide. It \Vlll now be understood that the ends of the guiderails are bowed or inclined downwardly to insure the guide-rollers engaging with the upper side of the guide as the trolley-wheel enters between the guide-rails.

\Yhen the device is supported solely upon a trolley-wire, as in Figs. 1 and 2 of the drawings, it is proposed to brace the same against lateral swinging movements by means of guys or braces 18, preferably in the nature of cables running from the lower portions of the terminal hangers 3 and with their outer ends anchored in the ground in any suitable manner (not shown) at a distance suliiciently remote from the railway-track to prevent inter :ference with the cars.

From the foregoing description it will be understood that the present guide may be assembled upon the ground. and then elevated and bodily supported upon the trolley-wire or upon a suitable support, as desired, and

socketed I therefore it is proposed to construct the device comparatively light, but of sufficient strength to withstand the lateral strains of the trolley-pole. \Vhen the device is assem i bled in con unction with the trolley-wire, it

l l l does not interfere with the passage of trolleywheels and does not require any particular form of trolley-wheel beyond the addition of guide-rollers upon opposite sides of the harp and concentric with the trolley-wheel.

Having fully described the invention, what is claimed is w 1. In an overhead-trolley system, the combination with a trolley-wire, of guide-rails located at opposite sides of the wire and provided with corresponding inwardly-directed substantially horizontal flanges, and a trolleywheel having guide-rollers at opposite sides to run between the guide-rails and upon the flanges thereof.

2-. A guide for trolleys consisting of a pair of spaced substantially parallel guide-rails, hanger members rising from the rails, crossbars connecting opposite hangers, and longitudinal bars connecting the hangers of the respective rails.

23. A guide for trolley-wheels comprising a pair of spaced substantially parallel guiderails having corresponding inwardly-dirccted flanges at their lower edges with their opposite ends inclined downwardly, corresponding hangers rising from the rails, cross-bars connecting the hangers, and longitudinal bars connecting the hangers of the respective rails.

t. An overhead-trolley system, the combination with a trolley-wire, of a pair of guiderails located below and at opposite sides of the wire, hangers rising from the rails, crossbars connecting the corresponding hangers of the two rails across the top of the wire, and seats pendent from cross-bars and engaging the top of the wire to support the guide.

5. In an overhead-trolley system, the combination with a trolley-wire, of a pair of guide rails located below and at opposite sides of the wire and provided with corresponding inwardly-directed flanges, hangers rising from the rails and extending above the wire, crossbars connecting the hangers above the wire, seats depending from cross-bars and resting upon the top of the wire, and a trolley-wheel for engagement with the under side of the wire to run between the rails and provided at opposite sides with guide-rollers to run upon the flanges of the rails.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

JOHN F. J AMESON.
