of which the following is a full, clear, andexact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to that type of electric railway in which a third. rail or other continuous current transmitter or conductor is employed.

The object of the invention is to provide a new modeof support for the conductor that will insure peri'ect insulation, safety from accidental contact, protection from rain, snow, ice, and dirt, and economy in installatron.

In the drawings: Figure 1 is a perspective View of one of the track rails, the conductor, the suspension device for the latter, a part of a car-truck and a contact device suspended therefrom and engaging the conductor; 2 is a transverse section of one of the track rails, the conductor, the devices for suspendingand securing the conductor, and a part of the contact device; Fig. 3 is a transverse sectional view of a modified construction; Fig. 4 is a detail sectional view of the suspension device of the modification; Fig. 5 is a detail perspective view of one of the hangers.

is one of the main track rails.

11 is a strip of non-conducting material, preferably that known commercially as fiber. These strips are secured to the track-rails and abutted end to end to form, like the track rails, a continuous structure designed to both support and .protect the The strip 11 is conductor.

Theweb of the track-rail is provided, at suitable intervals, with bolt holes into each of which is inserted a bushing 12 of non-con ducting material forming a boltreceiving orifice corresponoing to a bolt-receiving orifice in the strip 11. Through this orifice extends a bolt 13 provided with a washer 14. of nonconducting-material and a nut 15. secured to the outer face of track-rail and is preferably of shape in cross -section, the strip pwardly and at its outer wardly. The upwardlythe web of the curved edge somewhat do and State of Penn'- through curved part of the strip contacts with the lower outer edge of the head of the trackrail, thus enabling the track-rail itself to re sist the upward strain upon the conductor to which the latter is subjected.

At the highest part of is provided with bolt-receiving orifices to receive the hanger that directly supports the conductor. This hanger consists of the clamp 16 and bolt 17, the hanger being split the longitudinal centers of the clamp and bolt into two parts or halves. The upper part of the bolt the strip the latter 17, when the two halves of the latter are brought together, is.

circular in cross-section and screw threaded, while, the lower part of the bolt is tapered, the end of greater diameter adjoining the clamp 16. The bolt-receiving orifice in the strip 11 is'also tapered, the walls of the orifice converging from bottom to top.

The clamp 16 is of approximate semicylindrical shape in cross-section and is provided, at its lower side edge, with inwardly extending flanges 18 each having a Hat bottom and a convex inner face The conductor 20 is of approximately circular crosssection except that it is provided with two oppositely located grooves 19 having flat bottoms and concave sides; the grooves 19 corresponding in .size and shape with the flanges-18 of the clamp.

0n the bolt 17, between the bracket 16 and strip 11, is a washer 21. Surrounding the bolt 17, and above the strip 11, is an open-topped box-shaped washer 22 of nonconducting material, within which is a nut 23 engaging the threaded upper end of the bolt and passing down upon the washer 22.

To suspend the conductor 20 from the strip 11, the two parts or halves of'the j hanger 16*]? are engaged with the orifices 1 9 inthe conductor 20 and brought together and the bolt 17 carrying the washer 21 insorted from beneath through the orifice in the strip 11. The washer 22 and nut 23 are then applied and thelatter is tightened up until the bolt is securely wedged in the strip orifice. After the conductor is thus secured in position, non-comlucting material 24 is poured into the box-shaped washer 22 until the top of the bolt 17 iscovered, thus enabling the top of the strip'll to he handled without possibility of receiving current from the c onductor, holding the nut from rotation, and preventing any attack by moisture A modification adapted for surface roads and I against the connection between the hanger and strip.

, The contact device is composed of a frame 25, a pair of trolley wheels 26 journaled therein, and a supporting rod 27 suspended from the truck in any suitable known way. In the drawings, the rod is shown as extending through an orifice in. a lug; 28 on the truck 30 and is pressed upwardly by means of a spring 31 coiled about the rod and confined between said lug an d. a nut 29 on the top of the rod.

The foregoing construction is well adapted for use on ele ated railways, but for surface roads it is ordinarily desirable to elevate the conductor some distance from the ground.

also for a double track on which cars run in opposite directions is shown in Figs. 2, 3 and 4. For this purpose an inverted. T-bar 34 is supported between and at some distance above the two tracks and the strips 1. are secured to both sides thereof by means of a bolt 32 and nut The conductors are suspended from the strips 11 by means the same as those hereinbefore (l6SC1-ill)6(l, except that, in place of the washers or boxes 22, is substituted a cross bar 36, composed of non-conducting material and provided, like the washers or boxes 22, with recesses 37, 37 to receive first the nut 23 and then the nonconducting material 24. The cross-bar 36 serves also as a reinforcing strip or brace to take the upward thrust of the trolley. The contact device is the same as that hereinbefore described so far as the frame and wheels are concerned; but a horizontally extending lever 37 pivoted on the truck and pressed by the spring 38, may be substituted for the spring-pressed rod 29.

The T-bar 34is supported from pairs of standards 35 secured at intervals to the tics of the two tracks. The Tbars are abutted end to end to form a continuous bar.

Having now fully described my invention. what I claim'and desire to protect by Letters Patent is:
