Specification of Letters Patent.

PatentedlMarch 30, 1909.

Application filed January 6, 1909. Serial No. 470,920.

To all whom it may concern:

Be it known that we, GEORGE W. WHITE- MAN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, and HENRY R. LEONARD, a citizen of the United States, residing at Wayne, county of Erie, State of Pennsylvania, have invented a new and useful Tie- Plate, of which the following is a specication.

Our invention consists of a novel construction of tie plate which can be made of rolled or cast metal and is provided with a rib, rolled or cast or otherwise secured to the top surface of the plate, said rib being sheared out or recessed so as to give a proper bearing to the rail base on its underside and edges, the top of said rib being rolled, cast or otherwise shaped so as to cooperate with and substantially conform to the bevel on the underside of the head of the screw spilie or lag screw so that the underside of said head may coact with the contiguous portion of the upper surface of the rail base and the inclined surface of the rib whereby the rail, tie plate and tie may be properly and effectively held in assembled position.

A further object of our invention is in the provision of the center bearing for the rail base to lreep the center of pressure of the rail and its load as near the center of the tie plate and tie as possible, thereby insuring a incre even distribution of pressure on both the tie and underlying ballast, this center bearing feature of our tie plate with its more even distribution of pressure being in practice a very important feature since it lessens the tendency of the tie plate rocking on the tie and furthermore prevents cutting of the tie along the edges of the tie plate 'ri/hereby the life of the tic is greatly prolonged.

To the above ends, our invention consists of a novel construction of tie plate having' a rib preferably centrally located on the upper surface of the tie plate and recessed for the reception of a rail base, the outer edges of the tie plate which extend transversely to the rail base being beveled and adapted to receive fastening devices which are adapted to extend at an angle into the tie and the upper surface of said rib being beveled or shaped so as to substantially conform to the inclination of the underside of the screw spike, lag screw or other fastening device,

1t further consists of other novel features of construction, all as will be hereinafter fully set forth.

Figure 1 represents a side view of a tie plate embodying our invention showing the manner of assembling the rail, tie plate and tie. Fig. 2 re resents a perspective view of our novel tie p ate. Fig. 3 represents an end view of the same.

For the purpose of illustrating our invention we have shown in the accompanying drawing one form thereof which is at present preferred by us, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which our invention consists can be variously arranged and organized and that our invention is not limited to the precise arrangement and rganization of these instrumentalities as herein `shown and described.

Similar numerals of reference indicate oorresponding parts in the figures.

Referring to the drawings, 1 designates a tie plate, the same consisting of the body portion 2, from the underside 3 of which projects the longitudinally extending rib or spur 4, which is adapted to engage the tie 5, which may be of wood or other material.

6 designates the top surface of the tio plate, the latter having the longitudinally extended rib 7 rolled or cast on the top surface of the plate, said rib being sheared out or recessed as indicated at the points 8 in Fig. 1, whereby a recess or seat 9 is formed, upon which the base 10 of the rail 11 is seated, said rail base being prevented from lateral shifting by its Contact with the walls or points 8, as will be evident. The top surfaces of the recessed top rib 7 are rolled or cast or otherwise provided with the upwardly converging surfaces 12, the inclination or angle or bevel of said surfaces 12 substantially conforming to the angle of the underside 13 of the head 14 of the screw spike or lag screw 15, it being noted that the inclination or bevel of the underside 13 of the screw spike is substantially the same as the contiguous surface 12 of the rib 7 and the top 16 of the rail base 10, so that as the spike 15 is screwed into position on opposite sides of the recess 9, as indicated in Fig. 2, it simultaneously secures the tie plate to the tie and also secures the rail firmly into place by the coaction of the underside of the head 14 with the juxtaposed top surfaces 12 and 16 of the rib and rail base respectively. The outer edges of the tie plate are beveled as indicated at 17 and provided with the holes 18 in Which are located the screws, spikes or other fastening devices 19.

The preferred arrangement of the fastening devices 15 and 19 With respect to each other Will be understood from Fig. 2, wherein, it will be seen that the fastening devices 19 are located at opposite corners or ends of the plate and enter the tie plate on converging lines While the screw spikes 15 engage the opposite portions of the rail base and the rib 7 in such a Way that the rail is rigidly secured in position to the tie plate and the latter is rigidly secured to the tie by preferably four fastening devices which are applied in the most effective manner, so as torobtain the most efhcient results.

lt Will be apparent that our novel construction of tie plate may be rolled, cast or otherwise produced, the rib 7 being preferably integral with or simultaneously produced during the process of construction of the plate, or if desired the rib may be Welded or otherwise secured to the body of the tie plate Without departing from the spirit of our invention.

It Will be apparent that various slight changes may be made by those skilled in the art which Will come Within the scope of our invention and We reserve to ourselves the right to make all such changes as are Within the scope of the same.

Having thus described our invention, what We claim as new and desire to secure by Letters Patent, is:-

1. A tie plate consisting of a body portion, having a rib on the upper surface thereof, said rib being recessed and adapted to receive a rail base, the top surfaces of said rib being inclined and converging upwardly and adapted to co-act With the underside of the heads of fastening devices, the Walls of said recess being adapted to prevent lateral movement of said rail base.

V2. A tie plate consisting of a body portion, having a rib on the upper surface thereof, said rib being recessed to the level of the top of said tie plate and adapted to receive a rail base, the top surfaces of said rib on each side of the recess therein converging up- Wardly and the edges of said plate which extend transversely to said rail base being beveled so as to converge upwardly and having openings therein for the reception of fastening devices.
