WEAR-PLATE FOR RAI LROvAD-Tl ES.

SPECIFICATION forming part of Letters `llatent No. 249,407, dated November 8, 1881.

l Application filed April 6, 1881. (No model.) Y

To all whom it may concern:

Be it known that I,DAvrD SERVIs, of the city, county, and State of N ew York, have invented anew and useful Improvement in Wear- Plates for Railroad-Ties, of which the following is a specification.

Figure l is a plan view of my improvement, illustrating its use. vation of the same, taken through the line .r x, Fig. 1. Figs. 3 and 4 are Aperspectiveviews of modiiications of the improvement shown inverted.

Similar letters of reference indicate corre spending parts.

The object of this` invention is to increase' the durability of railroad-ties.

In the accompanying drawings, A represents a railroad-rail, and B is a tie, sleeper, orother timber upon which the rail A rests.

C is au iron plate of any convenient width, and of such a length as to pass beneath" the base of a rail, B, and project at both ends 4beyond the said rail, as shown in Fig. 1., Upon the lower side of the plate C are formed one or more ilanges, D, which are made thin, so that they can be driven into the tie or sleeper Blengthwise of the grain of the wood without splitting or otherwise materially affecting the timber. The plates C are designed to be made of such a widththat they will pass between the spikes E, that secure the bases of the rails to the ties or sleepers 5 or the plates (l can be made wider, as shown in'Fig. 3, in which case slots or notches F can be formed in the said plate (l, as shown in Fig. 3, to receive the spikes E. i When the plates Gare to be applied to the Y ties or sleepers B before they are laid or be- Fig. 2 is a sectional elefore the rails A are spiked to them the lian ges D can be made rectangular or wi th square ends,

- plates C prevent the base ofthe rail from Wearing and cutting the grain of the Woodand thus destroying the ties or sleepers, so that soft wood can be used for ties and sleepers, and Will last until destroyed by decay. With this construction, also, the flange or ilanges D strengthen the plates C, so that the said plates can be made light, and so that a pressure upon the rails will not bend or curve the plates, the said pressure putting the said ianges under a tensile strain, which firmly resists thetendency of the plates to bend.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent- In a Wear-plate for railroad-ties, the flange or flanges D, formed upon the lower side of the plate G, and beveled or rounded at one end, substantially as herein shown and described, to adapt the wear-plate to be driven in between a rail and a tie or sleeper Without` displacing the said rail, as set forth.
