EAIL R-OAD TIE.

Application filed July 7, 1822. Serial No. 573,395.

To all whom it may concern: which the rail rests. The rail is held on the Be it knownthat I, SIDNEY S. SMITH, a tie by means of a retaining spike of which 55 citizen of the United States, residing at 5 is the head and 6 the shank.

On the back side of the lower end of the spike is a projection 18 formed opposite the projection 7, the upper end of said projection terminating in the shoulder 17 Inclined edges or the projections 7 and 18 are preferably parallel so that as the spike is lifted, the'lower end will slide out from the inclined portion of the slot which is formed with parallel, opposing surfaces.

From the lower end of the spike, the opening in the tie is continued through the bottom oi the tie so that the entire opening can be cleared out before the spike and its keeper are inserted and whenever it is necessary to do so. The spike and the keeper are locked together to hold them in posi tion by double pin 20 extending through a suitable opening, halt oi which is in the spike and half in the keeper.

By the removal oi the pin 20 the keeper may be lifted by a bar under the projection 13 and having thus loosened the spike the latter may be readily pulled out from the recess in the tie.

It will be seen that my means of securing the rail and the tie together are extremely simple. The rail is held downwardby the strength. of the spike securely locked in the body of the concrete and whatever jar may come by the use of the track the spike is held solidly in place, although easily reinoved when d sired.

The vertical opening through the tie is, 1 course, carefully formed so as to exactly contain the spike and its keeper and when they are in place a solid body is formed,

firmly secured to the rail so that it cannot,

be disturbed by any jar or motion which may take place by the movement of the rail when in use. p

The device is designed to be used on both sides of the rail.

I claim a 1. A rail support including a concrete tie having a vertical recess extending therethrough, one of the walls of said recess being substantially coincident with the edge of the rail flange, said wall having a outunder portion, a retaining spike having its head overlapping said flange and having a lateral projection engaging said cut-under portion and having a ledge or shoulder formed atits lower end,'a keeper for said spike between the same and the rear wall of said recess, said keeper having inclined surfaces for "forcing it into contact with said spike, the lower end of saidkeeper contacting with said shoulder.
