ELECTRICAL CONNECTION FOR RAILWAY-RAILS.

SPECIFICATION forming part of Letters Patenthl'o. 285,494, dated September 25, 1883. Application filed February 12, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that l I, WILLIAM XV. LE GRANDE, a citizen of the United States of America, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Electrical Connections for Railwa -Rails; and I do hereby 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.

This invention relates to means for forming metallic connection between the adjacent ends of rails in a line of railwaytracks, its object being to connect said rails for the purpose of forming a continuous line of conductors for conveying electrical currents for actuating railway-signals and for railway telegraphic purposes. I

The invention consists in a metallic spliceplate adapted to lap the joints between the ends of two rails, in combination with one or more metallic plates having laterally-proj ecting spring-spurs arranged upon the inner side of said splice-plate, and suitable bolts passing through said splice-plate and spurred plate or plates, so that when said splice-plate is used to join two rails together the metallic plate having the spring-spurs will be clamped between the splice-plate and the web of the rail or rails, the lateral] y-proj ectin g spurs, owing to the movement of the rails by the action of the cars, scrape the I metallic surfaces against which they are pressed and prevent the accumulation of rust thereon, and thus insure effective electrical connection.

In the accompanying drawings, Figure 1 is a perspective view of the ends of two railwayrails connected as when in aline of track. Fig. 2 is a longitudinal section through the webs of the rails, splice-plates, and spur-plates. Fig. 3 is'a cross-section of a rail, splice-plate, and the spur-plate on the line 00 00, Fig. 2. Fig. 4 is a side view of one of the spur-plates detached, and Fig. 5 is an edge view of the same.

The letters A A indicate two railway-rails with their ends adjacent, as when in a line of track.

Bis the spliceplate, chambered, as shown at b, on its inner surface, so that while the margins of said inner surface may be in contact with the webs of the rails an intermediate space is left open.

0 C are the spur-plates, in the present instance being metallic disks, having bolt-holes through their centers and spurs c c projecting from their peripheries, these spurs being bent obliquely alternately in opposite directions. The splice-plates are provided with bolt-holes in the usual manner, and are secured to the rails by means of the bolts D. The shape of the spur-plates is not material, as they may be oblong, square, or of any other geometrical figure, and may have the spurs arranged to projectfrom their surfaces or peripheries in any desired order instead of regular alternating series, and, in fact, any metallic spring having laterally-proj ecting spurs maybe used. The spur-plates C C are arranged between one of the splice-plates and the adjacent webs of the two rails, respectively, said spur-plates being located in the chamber formed by the recessing of the splice-plates, and each of said spurplates has one of the fastening-bolts passed through its center for holding it in position.

It will now be observed thatwhen the parts are in position, as indicated in Figs. 1, 2, and 3 of the drawings, and the bolts properly tightened up, the spurs 0 will be pressed in contact with the webs of the rails and with the inner surface of the splice-plates. It will be understood that the spurs c of the spurplates are spread or bent laterally to such an extent normally that when they are clamped between the rail-webs and splice-plate they will be compressed and put under a consider- I to the almost continual motion of the rails under the travel of the cars the spurs c are caused to perform a scratching 0r scraping ac tion, which removes and prevents the accumulation of rust or extraneous matter upon the surfaces with which they are in contact, and which would impair the electrical connection between them and such surfaces.

I am aware that metallic springs have been arranged between splice-plates and rail-webs, and that bowed-spring spliceplates have been used in railway-joints, and I lay no claim to such joints, broadly.

\Vhat I claim is.

1. An electrical connection for railwayrails, consisting of a metallic splice-plate having arranged upon its inner surface a metallic plate provided with a series of laterally-projecti'ng pointed spring-spurs, arranged to bear against the rails, substantially as described.

2. The combination, with a metallic spliceplate and one or more bolts passing through the same, of one or more metallic spur-plates arranged upon the inner side of said splice plate, and having the belt or bolts thereof which bear against each rail, substantially as described, and for the purpose set forth.

5. The combination, with the rails A A, chambered or recessed splice-plate B, and bolts D, of the metallic spur-plates 0, sub stantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
