SWlTGl-i FOR SUSPENDED ELECTRIC CONDUCTORS.

SPECIFICATION formingpart of Letters Patent No. 670,274, dated March 19, 1901.

Application filed February 2,1900- SerialNo. 3,720. (No model.)

To aZZ whom it" may concern:

Be it known that 1, JOHN FLOYD, a citizen of the United States of America, residing at Washington,in the District of Columbia, have invented certain new and useful Improvements in Switches for Suspended Electric Conductors, of which the following is a specification.

This invention relates to switches for suspended electric conductors, and more particularly to that class in which the trolley-wheel travels on the top of the conductor.

One object of this invention is to provide a switch for suspended electric conductors which will afford means whereby the trolleywheel when traveling on top of the main conductor may be switched off on the branch conductor without necessitating the removal of the wheel or decreasing the speed of the car.

Another object of this invention is to provide a switch for suspended electric conductors which is neat and compact and will efficiently perform all of its intended functions.

For the attainment of these objects and for other purposes which may hereinafter appear my invention consists in the novel manner of construction, arrangement, and combination of parts, all of which will be described, and specifically pointed out in the claims.

In the accompanying drawings, in which like parts are indicated by the same letters, Figure 1 is a perspective View. Fig. 2 is a modification.

Referring by letters to the drawings, A represents the main conductor, in the body of which is formed a downwardly-projecting U-shaped curve B, through which one flange of the trolley-wheel passes when the wheel is guided off on the branching conductor. Brazed or otherwise secured beneath the main conductor at a point approximately near the curve B is the branching conductor O, which curves outwardly and thence back to the curve B, forming a loop D, adapted to be engaged by the revolving sleeve upon the trolley-pole when it is desired to guide the trolley-wheel to the branching conductor. From the curve B both the main and branching conductors extend for a short distance parallel with respect to each other, yet not in is somewhat lower and eventually curves under the main conductor at the switohiin the track. Brazed to the loop D is a guide-rod E, the free ends of which are brazed on the main and branching conductors, respectively. This guide-rod E is designed to strengthen the construction of the switch and is also adapted to perform the same function as the loop D in guiding the trolley-wheel from the main to the branching conductor.

In Fig. 2 I have shown a modified form of my invention, which consists in abandoning the guide-rod and forming it in the body of the branching conductor F by extending the loop D beyond the curve B, as plainly shown in the drawings.

In carrying my switch for suspended electric conductors into operation I find it necessary to employ a trolley-pole G, having a sleeve H, which will revolve freely thereon approximately near the top, and an adj ustable arm I, adapted to support the trolleywheel J in such a manner thatit will continue on the main conductor or take the branching conductor, as may be desired. When it is desired to continue on the main conductor, the arm is adjusted so as to set the wheel out, and when it is desired to turn off on the branching conductor the arm is adjusted so as to set the wheel in nearer the pole, in order that the sleeve therein may engage the guide-rod E or loop D, and thereby guide the wheel on the branching conductor.

It will thus be seen that I provide a switch for suspended electric conductors which is exceedingly cheap and simple in its construction and one that will be readily understood by all conversant with such matters.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a switch for suspended electric conductors, a main conductor having a downwardly-projecting curve, of a branching conductor brazed to and forming a loop against the main cond uctor,the said main and branching conductors extending parallel, of the branching conductor running under the main conductor, a guide-rod brazed to the loop, its free ends brazed to the main and branching conductors respectively, substantially as shown and for the purposes set forth.
