TIE-PLATE.

SPECIFICATION forming part of Letters Patent No. 717,819, dated January 6, 1903.

Application filed August 16, 1902.

To all whmn it may concern:

Be it known that I, J OHN HENRY CROWLEY, a citizen of the United States, and a resident of Duluth, in the county of St. Louis and State of Minnesota, have invented a new and Improved Tie-Plate, of which the following is a full, clear, and exact description.

This invention relates to improvements in railway tie-plates or rail-chairs, the object being to provide a tie-plate of simple construction that may be manufactured at acomparatively low cost and that may be quickly placed in position and when in place will prevent spreading or rolling of the rails.

I will describe a tie-plate embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a plan view showing tie-plates embodying my invention. Fig. 2 is an end view thereof, and Figs. 3 and 4 are perspective views of the plate.

Referring to the drawings, 1 designates the body of the tie-plate, and on the upper side of the plate are the transverse ribs 2 and 3, which are sufiiciently spaced apart to receive the basaflange of a rail. The flanges extend from opposite edges of the plate and terminate somewhat inward of the opposite edges. The space between the ends of the ribs and the edges is provided with spike-holes 4 and 5. These spike-holes4 and 5, as will be seen, are so placed that the heads of thespikes will engage over the base-flange of the-rails, as indicated in Fig. 1. The plate is also provided with other spike-holes 6, through which spikes may pass into the wooden ties. The rib 2 has its upper edge curved inward to en.- gage with the top surface of the inner or outer portion of the rail, as may be desired. The rib is formed in this manner during the casting or making of the plate. The rib 3, however, is left in vertical position and is designed to be turned down upon the outer edge of the rail-base by any suitabe means. As one rib is turned as described it is obvious that the plate may be quickly inserted Serial Nox 119.930. (No model.)

between the rail and a tie and the rib 3 quickly turned down.

As railway-rails are slightly convexed on their under sides, which is done in the rollingprocess, I concave the upper surface of the plate 1 between the ribs2 and 3, as clearly indicated at 7. This will permit the rail to rest firmly with its base edges upon the plate and prevent any possible rocking motion as might occur if the concave or rounded surfaces were allowed to rest directly on a plate. The inner end of the plate is provided with a slot 8 to receive a head 9 of a tie-rod 10, and extended over a restricted outward opening of the slot 8 is an arched member 11, under which the tie-rod passes, and the inner surface of this arched member engages against the head of the tie-rod. These tie-rods are to be made of a length to suit the required gage.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-.-

1. A railway tie-plate, and upwardly -extended parallel ribs on said plates, said ribs being extended from the opposite sides of the plates nearly to the other sides, the plate being provided with spike-holes at the ends of the ribs, and the plate being concaved between the ribs.

2. A railway tie-plate and upwardly -extended parallel ribs on said plate, one of said ribs having its upper edge curved to engage the base of a railway-rail while the other rib is adapted to be turned down upon the base of the rail.

3. A tie-plate devices on the plate for engaging with a rail-base, the plate being provided near its inner edge with a slot having arestricted outward opening, an arched member extended over the restricted opening, and atie-rod provided with heads for engaging in the slots of opposite plates, the said rod being of alength to conform to the railway gage.

"In testimony whereof I have signed my name to this specification in the presence of two subscribing witneses.

JOHN HENRY CROWLEY.
