THIRD-RAIL CONDUCTOR.

SPECIFICATION forming part of Letters Patent No. 7&1,613, dated October 20, 1903.

Application filed March 4, 1903- Serial No. 146,156. (No model.)

To all whom it may concern:

Be it known that we, FRANK T. BAILEY and CHARLES S. MICKEY, citizens of the United States,residin g at Baltimore city, St ate of Maryland, have invented certain new and useful Improvements in Third-Rail Conductors; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in third-rail conductors adapted to be mounted upon ties of a railway and affording means whereby communication may be had electrically between a train having electrical apparatus in connection with tions for the purpose of signaling the ap proach of trains or the location of the same with reference to each other or to stations.

More specifically, the invention comprises a conductor apparatus consisting of a suitable insulated conductor-way and suitable insulating material held by suitable tie-clamps which are adapted to be fastened to the ties of a railway.

Our invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings similar letters of reference indicate like parts in the several views, in which- Figure 1 is a perspective view of a portion of our third-rail conductor shown as held by tie-clamps. Fig. 2 is a perspective view of one of the insulating members in which the conductors are mounted. Fig. 3 is an enlarged detail view of one of the tie-clamps. Fig. 4 is an end view of the tie-clamp. Fig. 5 is a detail view of one of the intermediate clamps, and Figs. 6 and 7 are detail views of one of the intermediate clamps separated.

Reference now being had to the details of the drawings by letter, A designates one section of the conductor-holding blocks, which may be made of any suitable insulating material, as Wood or other fiber, and in the drawings we have shown said block as longitudinally recessed, as at A, to carry two conductors B, although any number of conductors may be used. The ends of said blocks A are supported in the tie-clamp members 0, each of which is recessed out on its top, as at O, and has an aperture D running longitudinally through the member, and a slit D is out through the bottom of the recess G into the aperture D for the purpose of allowing the side walls of said member to clamp more securely the opposite edges of the blocks A when the clamping-bolts E, which pass transversely through apertures in said member, are screwed up. The flanges F of said clamping members are recessed, as at F, to receive spikes, whereby said members may be securely fastened to the ties of a railway.

Intermediate the members 0 are the clamping-jaws K and K, through which a bolt L is passed, whereby the two jaws may be securely held against the opposite edges of the blocks A. One of said jaws K has a lug K projecting at right angles from its lower end and designed to engage a notch N in the block K when the two are clamped together in the position illustrated in the drawings by means of a bolt M, passed through said jaws.

By the provision of the clamping means described it will be observed that the conductors maybe securelyheld by the blocks, which are clamped tightly by said jaws and also by the clamping members which connect the ends of the conductor-carrying blocks.

While we have shown a particular form of apparatus embodying our invention, it will be understood that we may make alterations in the detailed construction of the same, if desired, without departing from the spirit of the invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1. A third-rail conductor comprising a series of channeled insulating-blocks with electrical conductors therein, tieclamps adapted for attachment to the ties of a railway and having recesses to receive said conductorcarrying blocks, and means for clamping said members against the opposite sides of the blocks, as set forth.

2. A third-rail conductor for railways, comprising a series of conductor-carrying blocks with channels therein, tie-clamps having reing members adapted for attachment to the ties of a railway and recessed to receive the meeting ends of the conductor-carrying block, and intermediate clamping-jaws, and means for holding the same opposite each other, and bolts for retaining the jaws in clamping relation with the opposite faces of said conductor-blocks, as set forth.

In testimony whereof We hereunto affix our signatures in presence of two witnesses.

FRANK T. BAILEY. CHAS. S. MICKEY.
