- T at whmn it nuty concern:

Be it known that I, JOHN A. GAREY, a citizen of the United States, residing at Tarkio, in the county of Atchison and State of Missouri, have invented a new and useful Electric Railway, of which the following is a specification.

This invention relates to electric railways, and more particularly to the construction and arrangement of the third-rail supports and the conduit.

A still further object of the invention is to provide for the ready removal of accumulatlions of dirt and foreign matter from the con L uit.

With these and other-objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of con struction and arrangement of parts, hereinafter fully described, illustrated in the ac companying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departingfrom the spirit or sacr ficing any of the advantages of the invention.

In the accompanying drawings, a sectional elevation illustrating a portion of a third-rail system and current-collecting devices arranged in accordance with the invention. Fig. 2 is a transverse sectional View of the same. Fig. 3 is a detail sectional view of the current-collecting wheel, drawn to an enlarged scale.

Similar characters of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

In carryin out the invention a conduitis formed by p acing a pair of spaced sills or beams 10 on cross-ties 11, the latter being of any suitable construction and the sill members being usually formed of wood. At intervals hollow ties 11 are introduced for the reception of dirt and foreign matter which may accumulate in the conduit and which is removed by the action of the plow, and said ties also serve as drains to permit the passage of rain-water, said ties being connected to sewers or sewer inlets, if necessary. The hollow ties are open at both ends, so that by introducing a scraper, such as as, the dirt may be readily drawn out from time to time. In

Figure 1 is some cases where the ties are embedded in the concrete or their upper surfaces are made flush with or below the level of the street suitable doors 12 may be employed, the doors normally closing the ties, but when open permitting the ready removal of the dirt.

The sill members 10 are provided with slotirons 13, which extend some distance over the adjacent edges of the sills to form a contracted slot for the passage of the slot-bar or plow-carrier 14, and the inner faces of said sills are preferably sheathed with metal to resist wear. i

The third rail 16 is mounted on the cross ties and is suitably insulated therefrom, said rail in some cases being elevated on a supporting-base 17 of angular cross-section to permit the ready discharge of dirt, as shown in Fig. 1.

The slotbar 14 extends through suitable guides formed in frame members 18 and 19 and is normally held depressed by a helical compression-spring 20, that tends to force the bar downward in a direction of the third rail. At the lower end of the bar is a plow shaped frame 21, to the bottom of which is secured a brush 22, that is insulated from the frame, said brush being formed of metallic or non-metallic material and being designed to clear'the rail in advance of the engagement of the currentcollector therewith. From the rear portion ofthe frame extend arms 23, having bearing-boxes for the support of a shaft 24, on which 1S mounted a hub 25, suitable ball-bearings being introduced between the shaft and hub to permit the free rotation of the latter. To this hub 25 is secured a wheel formed of a pair of disks 26, the peripheries of the disks being inclined to form a groove that is wedge shape in cross-section and is designed to receive an annular currentcollector 27 of approximately triangular form in cross section. The disks 26 are formed of non-conducting material, so that further insulation of the wheel is unnecessary. Secured to and insulated from the lower portion of the slot-bar is a contact-finger 28, that bears against the periphery of the collector 27, and to the rear end. of this finger is secured a bar 29, conducting wire or wires may lead.

In operation the plow in traveling through the conduit will brush the dirt from the rail, the dirt moving forward until it falls into one from which the current-- of the hollow ties 11, and as said hollow ties are arranged at frequent intervals the conduit will be kept clear, so that good electrical contact with the current-collector will be insured. The dirt may be readily removed from time to time without danger to the workmen.

Having thus described the invention, what is claimed is 1. In apparatus of the class described, third-rail supports including hollow cross ties arranged at intervals, and' means for forcing accumulations of dirt and foreign matter into such cross-ties.

2. In apparatus third-rail supports including hollow crossties arranged at intervals and serving as dirtreceptacles, and means carried by the car or other vehicle for forcing dirt from the conduit into such cross-ties.

3. In apparatus of the class third-rail support including hollow crossties arranged at intervals and forming dirt receptacles, a plow, a current-collector supdescribed, a

means carried by the plow for cleaning the rail in advance of the collector, and forcing the dirt and other foreign matter into said hollow cross-ties.

4. In apparatus of the class described, a third-rail support including hollow crossties arranged at intervals and forming dirtreceptacles, a supporting-sill for the third rail, and means carried by the car or other vehicle for forcing accumulations of dirt and foreign matter from the rail into such crossties.

i 5. In apparatus of the class described, a l third-rail support, and cross-ties or troughs lforming dirt-receptacles arranged at intervals and disposed below the level of the thirdrail support.

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