TIE PLATE Fled June 18. 1929 M/vENToR Bumm/Inn f: aa'KnAN ATTO and u Patented June 24, 1936 TES lstie TIE PLATE Application filed .Tune 18,

This invention relates to tie-plates for railway rails, its object being to provide a device of that character which shall be economical in manufacture, convenient in its application to the rail and tier and which shall be rigid in its construction, firmly holding the rail in position. Further objects are to make the plate adjustable as to various widths of the base flanges of the rails, and to provide extensive surfaces of contact between the plate and the tie.

In the accompanying drawings I have shown that form of tie plate which is now preferred; but the claims herein are not intended to be limited to the exact structure shown any further-,than their express terms make necessary. f

In the said drawings, Fig. 1 is a perspective view of my preferred form of tie-plate, the same vshowing the two members of the plate separated or spaced apart in order more clearly to illustrate the specific structure; Fig. 2 is a plan view of the said tie-plate on a reduced scale, with the parts assembled; Fig. 3 is a section through the tie-plate of F ig. 2, taken on the broken line 3 3 thereof, and showing the manner in which the elements making up the plate are assembled with reference to the tiev and the railway rail.

That form of tie-plate which is shown in the drawing comprises two members, A and B, which are similar in shape to the letter L. These members are identical in structure and are interchangeable. Each member at the angle of the L may be said to be of double thickness, as indicated in the portion marked 10. As will be seen from Fig. 3, this thickened portion is adapted to rest directly upon the tie, which is indicated at 11. v`The thickened portion extends for substantially half the length of the member A or B, beyond which Vthe member is cut away on its lower side to form a relatively thin extension 12. Extending longitudinally of the rail from the thickened portion 10 is another thinned extension 13. As will be plain from Fig. 1, the thinned portions 12 and 13 are at right angles to each other; and, whereas the portion 12 projects from 1929. Serial 310.371,783.

the upper part of the thickened portion 10,

the thinned portion 13 projects vfrom the lower part of the thickened portion. When the tie-plate is assembled, as shown in Figs. 2 and 3, the part 12-of one member lies upon thc part 13 of the other member. These parts are each of substantially half the thickness of the part 10, so that the assem bled plate is ofuniform thickness throughout, except that, in applying it to rails having base flanges of different widths, `or to ties of greater or lesser widths, the members may be spaced apart more or less, as indicated at 14 in Figs. 2 and 3.

Extending upwardly from the upper-.surfaces of the thickened portions 10 of the members A and B are hooked projections 15, which are adapted to extend over the adjacent base flanges of the rail, which is indicated at 16. In assembling, the mem bers A, and B are applied beneath the rail from opposite sides of the latter until the hooked projections come into substantial contact with the base flanges of the rail.

The thinned portion 13 of each of theV members is provided with an elongated'slot 17, while the thickened portion 10 is provided with a spike hole 18 and the thin portion 12`with a similar spike hole 19. When the tie-plate is assembled, the holes 19 register with the elongated slots 17 so that spikes 2O may be inserted through the holes and slots into the tie 11, as shown in Fig. 3. Because of the elongated slots, the members maybe spaced transversely of the rail more. or less and still permit the insertion of the spikes 20. In thisy way, therefore, the tie plate ismade adjustable for various widthsof base flanges of the rails. vFor holding down the thickened portions 10 ofV the members, spikes 21 are passed through the holes 18 and forced into the tie.

The parts above described may be made out of any suitable material. The portions which engage with the tie have extended areas in contact with the latter so that the hammering incident to heavy traffic results in comparatively little damage to the ties. Ihe holes which are necessarily made in the ties or spaced substantial distances from the rails and the material of the ties beneath the rails and adjacent the edges of 'the base flanges of the latter remain intact and in condition for sustaining the stresses due to heavy tratlic. Further, when the bolts or screws are set down tightly against the tieplate members, the parts which are in contact with the tie are drawn tightly against the latter, thus slightly conipressing the libers of the tie and preventing moisture from reachingtheholes in the tie.

Having thus described my invention what I claim as new is:

l. A tie-plate comprising a pair of niembers which are adapted to be assembled from opposite sides oi the rail, each of said ,members comprising a thickened portion adapted to rest upon the tie, a thinner portion extending from the thickened portion in the direction oi" the rail and also adapted to rest upon the tie, and a second thinner portion extending' from the thickened portion transversely of the rail and adapted to overlap the first mentioned thinner portion of' the opposite member, the lirst mentioned thinnerr portion of each member being provided with an openingl therethrough and the second thinner portionshaving openings therethrough adapted to register with the lirst mentioned openingsV for the reception of means for securing the members to the tie.
