TIE PLATE.

Application filed June '23, 1924 Serial No. 721,671.

To all whom it may concern:

Be it known that I, Tnnononn \Vnnacu, a :itizen of the United States, residing at Medical Lake, in Spokane County, and State 7E Washington, have invented certain new 1nd useful Improvements in Tie Plates, of which the followingis a specification.

My present invention relates to improvements in tie plates for use in railway con- ;truction and designed as a practical comparatively inexpensive and efficient means for securing the railway rail to its ties. ;As is well known in track laying and railway operations it is imperative that creeping. lateral movement, and tipping or tilting of the rails shall be prevented, and that the tie plate itself be rigidly fastened to the tie. For compliance with these requirements my tie plate'has been especially constructed.

The invention consists in certain com binations and arrangements of features of constructlon in a single, integral, t e plate,

as will be hereinafter more fully set forth v tegral, overhangin inwardly toward t e longitudinal center of and claimed.

In the accompanying drawingsI have illustrated one complete example of the phys ical embodiment of my invention wherein the parts are combined and arranged accordingto the best mode I have thus far devised for the practical application ofthe principles of my invention. I

Figure 1 is a view showing a standard railroad rail in cross section, and a tie plate constructed according to my invention securing the rail in place on a portion' of a cross tie.

Figure 2 is a perspective view ,of the tie plate showing in dotted lines the relation thereto of the rail. I

Figure 3 is a bottom plan View of the tie plate.

For purposes of illustration I have in-w dicated in Figure 1 a portion of a tie T and a standard railway rail with its head H, web W and base B, the latter havingthe longitudinal flanges B and B as usual.

The tie plate 1 is of rectangular shape having on its bottom intersecting ribs 2 which extend longitudinally across the plate in two series, the parallel ribs of one series intersecting the parallel ribs of another series. These ribs are designed to'be embedded in the top surface of the wood tie T and because of their arrangement and disposition on the bottomof the plate, the

,tion with the tie'plate.

.the tie plate, against which shoulder the edge of the flange B of the rail abuts when the tie plate and rail are properly 'positioned.

A plurality of spike holes 5 are provided for the spikes, as S, which holes ex tcnd through the lug 3 and the plate for the accommodation of the spikes, ir 1 order that the lip S of the spike as seen in Figure 1 will project 'over the edge of the flange B of the rail base. "By this arrangement of parts the edge of the rail base is retained in close engagement with the shoulder 4 and the lip of the spike holds the edge of the flange down on the tie plate.

Near the opposite side of the tie plate on its upper surface is fashioned an inflange 6 which extends.

the plate and is provided with an undercut space 7 atits junction with the body of the plate. On its under side the overhanging flange is fashioned with a contact rilxs prevent horizontal movement of the face 8 for frictional engagement with the;

topinclined surface of the. flange B, of the rail. The flange is undercut in order that the space 7 may afford clearance for the rail-flange, and to insure a resilient or 3 spring-like frictional pressure of the flange 8 on the rail-flange without subjecting the flange 6 to strains that would 0therwise tend to break off the flange at its junc- The surface 8 is also inclined to conform to the inclination .of the top surface of the rail flange to insure a wedge. and close frictional engagement of these arts.

A single spi e hole 9 extends through the tie plate at the outer side of the flange 6 for the reception of a spike that is driven therethrough and into the railway tie.

In assembling the plate and rail, the body of the plate is slipped under the rail base with the flange 6 extending over and embracing the flange B of the rail base. Then the plate is driven or forced in'direction transversely of the rail in order that a Wedge action may be secured "between the plate and its flange over the-flange of the railplate are now lowered to the tie and the inside and outside of the rail.

V spikes S are driven through the spike holes to secure the plate and rail'to the tie.

The tie plates are spaced at the required intervals along the rail where hecessary, and

as the plates are interchangeable, the flange I 6 of the'plate may be located at either the insideor the outside of the rail. In some instances the plates may be arranged with the flanges 6 in alternate positions at the When the plates are in use it will be apparent that the railis held in position against lateral displacement ineither direction and against tilting movement, as well asagainst excessive creeping movement.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent is Y A tie plate having on its bottom two series of diagonally extending, intersectin a longidutinally extending integral lugon its upper face and an inner shoulder on said lug perpendicular to the top surface of the tie plate, and a spaced overhanging parallel flange with an undercut clearance at its junction with the top surface of the plate and fashioned with an inclined frictional contact face on its under side.

In testimony whereof I afiix my .signature.
