CONTACT-RAIL APPLIANCEFOR ELECTRIC RAILWAYS.

SPECIFICATION forming partof Letters Patent No. 610,008, dated August 30, 1898. Application filed February 2, ISQSl Serial No. 668,906. (No model.)

citizen of the United States, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Running Contact-Rail Appliances for ElectricRailways, of which the following is a specication.

This invention relates to running contactrail appliances for electric railways, the object of the invention being especially to provide double rail-conductors having the general location of the third rail, as nowwell known, between the ordinary traclcrails and preferably in a conduit below the surface of the railway, the said double conductors being combined and arranged with a common support therefor by which the one is insulated from the other, each being continuous, and also protected against dirt, snow, water, or any substances falling thereupon to interfere with the contact `therewithof a device having double shoes adapted to run on the separated continuous and insulated conduc tors and comprised in a device havinga rolling contact and guiding-support on the top of the aforementioned common support.

The invention consists in the continuous insulated and separated double contact-conductors and the peculiarly-constructed common support therefor, as hereinafter described and claimed, and in the combination therewith of'an underrunning double `trolley or shoe constructed as hereinafter set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, in whicln- Y Figure 1 is a cross-sectional `view of an underground conduit understood as between the two track-rails `of a street-railway and showing the double contacts,the line and return wires in connection therewith, and the double bearing-shoe or trolley. Fig. 2 is a sectional elevation longitudinally of the same.

A represents the underground conduit supporting therewithin between its top and bottom the ties a a, which are arranged crosswise at proper intervals and which support centrally and longitudinally below the top `slot b the rail B,suitably held in place, the same being formed of a hard, durable, insulating material, having its top of inverted-V form and provided with the sections d d, arranged to overhang the sides of the rail in `the manner of eaves7 and having at its apex lthe inVertedV-shaped longitudinally-conltinuous metallic bearing-plate f for the supportingand guiding roller s of the trolley or double-contact-shoe device C.

g 7L represent longitudinally-continuous contact-conductors or supplemental rails having the dovetailed Shanks, these being embedded in the opposite sides and conned ,to the rail B, which constitutes not only the common support for both thereof, but also means for insulating the one from the other. The support-rail B may be constructed of the form substantially as shown, with the said contact-conductors g 7L embedded by their dovetailed portions therein by molding, while the substance from which the rail B is in a plastic condition, such substances being understood finally hardening and holding the sections g h immovably therein.

t' indicates the line feed-wire, and j indicates the line return-wire', both having connection, respectively, with the continuous contact-conductors by the bond-wires i2 j? The trolley device C consists of a body or holder m, whereby it is adapted to be sustained pendentbelow the car-body-or the cartruck, the same having laterally-extending members in pairs, as indicated at 'n n, which are perforated and through which pass the dependent stems or rods o o, the surrounding springs p exerting a downward pressure against the members n of the trolley-support. The said trolley-support is provided with the `forward and rearward yokes q, journaled within which are the grooved rollers s, adapted to run on the angular Wear-plate f on the top of the insulating and supporting rail B, aforesaid. y y l represents the oppositely-disposed shoes or trolley-contacts arranged in the form of beams to bear sidewise against the aforesaid contact-conductors g h, they being respecn tively carried by the depending arms u, pivotally hung in pairs to the lower portion of IOO the trolley-support fm. The said trolley-support has depending below each side thereof, preferably at its middle, the rigid arm between each of which and a portion of the beam-shoe or contact member if is interposed a spring y.

The trolley device is susceptible of vertical movements against a yielding downward pressure, and it has centrally and vertically within the top of the supporting-body m the vertical socket z, in which plays the depending guide-post r, which is sustained by the car-body or truck-frame.

One of the shoes t may be carried upwardly by wire 152 through the center of the trolleysupport m and through the post r, which parts may be tubular,`to connection with the motor, while the return current may be brought by a similarly-disposed Wire t3 back from connection with the motor to the other contact-shoe.

Should anything fall down through conduit-slot onto the top of the support-rail B, it would, by reason of the downwardly-sloping and overhanging guard-sections d d, be downwardly directed and conveyed to fall into the bottom of the conduit, or, in any event, be prevented from lodging on the continuous contact-conductors g or 7i, on which the opposite beam-shoes of the double trolley device have spring-pressure bearing contact.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with the support-rail B of insulating material provided at opposite sides with the contin nous lon gitudinally-ranging metallic contact-conductors, of a doubleshoe trolley device consisting of a depending trolley-support m having a roller-carrying yoke to run on the top of the support-rail and tallic contact-conductors which are bonded to said feed and return wire, and having an inverted -V- shaped top formation with the eaves overhanging said contact-conductors, and provided at its top with the angular wearplate, of the trolley device C consisting of the downwardly spring-pressed support m having at its forward andrearward ends the yokes q q with V-shaped rollers journaled therein to run on the angular wear-plate of said rail and provided with the downwardly-depending rigidly-supported bars a: at opposite sides, the pivoted supporting-bars u u carrying the contact-shoes t t and the springs y y interposed between said depending barsand the shoes, all substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this'22d day of December, 1897.
