To all whom it may concern:

The meeting edges of and useful Improvements in Electric Rail adjacent working conductor sections are se ways, of which the following is a specification. cured together by plates and held by bolts 8, as shown in Fig. 3.

This invention relates to electric railways, having special reference to that class in which will be understood that current is supplied to this third rail to be collected therefrom by the H tlllltl l'itll 01' W orkin conductor is 31'- the trolley 01' SlTOG.

The primary object of the invention is to the equalizing bar indicated at 10. I have provide improved, simple and efficient means shown a wire conductor 12 attached directly to plate 9 and designed to conduct the ourfor supplying current to the car motor from rent from the latter to the car motor.

So far as I am aware, the broad idea to pending from either end of the plate 9 is an which my invention relates has failed of uniarm 13. These arms are connected at their lower ends by a shaft or journal 14 upon versal adoption because of the extensive workmanship required by the means heretowhich are pivoted cars 15 of the trolley supporting arms 16 carrying at their outer ends fore suggested, such as the provision of pedestals or brackets to support the third rall the current collecting shoe 17. Springs 18 are secured to the arms 16 and to plate 9 and in the provision of insulation between the rail and its support, and because the and tend to hold the arms 16 and the shoe above a horizontal position so'as to insure wires or other current conductors leading to the motor have been so connected to the shoe effective contact between the shoe and the working conductor.

In addition to the obvious simplicity of construction and conse- 5. The upright portions 2 of each section spanning the edges sary to remove the shaft 14 in quent cheapness of installation, it will be noted that the invention requires few parts not likely to become broken or deranged. If, however, the shoe or its supporting arms should be broken by accident another may readily be substituted since it is only necesarate the arms 16 from their supports. At the same time, as will be appreciated by trainmen, the conductor wire leading to the motor is not interfered with, or, at least, is not likely to be in any of the commonly occurring accidents causing damage to the shoe.

I claim as my inventionz- In an electric railway, the combination with the way or tracks and the working conductor arranged adjacent the way and. parallel thereto, of a frame designed to be rigidly mounted on a car movable on said way, a conductor wire leading from said frame to the car motor, said. frame having order to sep-' side arms, a shaft connecting said arms, a trolley support having plates or flanges journaled on said shaft and forming engaging lugs or projections, stops on the inner faces of said arms designed to co-act with said lugs to limit the movement of said support, said plates or flanges contacting with the faces of said arms, and a trolley or current collecting shoe carried by said support and engaging said working conductor, all of said parts comprising the trolley support being of conducting material, for the purpose stated.

In testimony'whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this 12th day of May 1906.
