RAILWAY-TIE PLATE.

SPECIFICATION forming part of Letters Patent No. 777,253, dated December 13, 1904.

Application filed October 2, 1903. Serial No. 175,443. (No model.)

.To all whont it may concern:

Be it known that I, WILLIAM F. GOULD, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa,have invented certain new and useful 1mprovements in Railway-Tie Plates, of which the following is a specification.

This invention relates to that class of tieplates in which the rail-engaging surface is tapered or inclined from its outer to its inner end for the purpose of tilting the top of the rails inwardly.

My objects are to provide a railway-tie plate of this class having longitudinal railrests elevated above the surface of the plate and so arranged that after considerable use and Wear has taken place a new rail havinga wider flange may be placed on the plate and lie flat upon the top of the raised rail-rests. When a rail is placed on top of asmooth-surfaced tie plate and after considerable wear has taken place, a rail with a wider flange placed on the same plate would partially overlap the unworn portion of the plate, and hence would not lie flat upon the whole rail-supporting surface of the plate. v

A further object is to provide a tapered plate susceptible of being changed from one rail to the other of a track and of being used either beneath the angle-bars at the railwayrail joints or throughout the length of the rail itselfthat is to say, a single plate is pro- Vided having only two spike-openings, which may be used for any of the above-described purposes.

A further object is to provide a tie-plate having ribs on its under surface to enter a tie and shaped to interlock with the wood fibers in suchaway as to prevent upward movement of the tie-plate relative to the tie; and a further object is to provide an invertible tieplate having raised rail-rests on each side so shaped as to sink into a tie and to cover and protect the broken fibers of the'wood of the tie at the points Where they turn'upwardly at the edges of the rail-rests.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of the tie plate whereby the objects above contemplated are of same.

attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in Which Figure 1 shows a sideview of my preferred form of tie-plate resting upon a tie and having a rail supported thereon and angle-bars connected with the rail and spikes for holding the rail and tie-plate to the tie and also by dotted lines showing the position of the various parts when a rail having a wider flange is placed on the same tie-plate. Fig. 2 shows in perspective my preferred form of tie-plate. Fig. 3 shows in perspective a modified form Fig. 4c shows a side view of the plate illustrated in Fig. 3, the ribs thereon being provided with openings to receive the fibers of a tie. Fig. 5 shows an edge view of the form of another modified form of my improved tie-plate with a rail and anglebars resting thereon and held in position by spikes. Fig. 6 shows a similar view with the plate inverted and the angle bars omitted; and Fig. 7 shows a plan view of a part of a railway-rail resting on ties, showing two of my improved plates supporting the rail and the angle-bars at the ends of two abutting rails and also showing a similar tie-plate inverted supporting the rail itself.

Referring to Figs. 1 and 2 of the accompanying drawings, my preferred form of tieplate comprises a flat body portion having on each surface two parallel raised rail-rests extending longitudinally of the rail. The outer rail-rest (indicated by the numeral 10) is of greater thickness than the inner one, 11, and between theserail-rests is a longitudinal channel 12. At the outer edge of the outer railrest is a curved inwardly-inclined shoulder 13, and at the inner end of the inner rest is a similar shoulder 14:. Beyond the rail-rest 10 that is to say, at the outer end of the tieplate-is an extension 15, having a tapered edge 16 and a spike-opening 17 the inner edge of the spike-opening being flush with the outer edge of the rail-rest 10. At the inner end of the tie-plate is an extension 18, having a tapered edge 19 and a spike-opening 20. This spike-opening is materially longer than is necessary for an ordinary spike, so that a spike may be driven through the opening 20 close to shoulder 14 or at some distance from said shoulder.

In practical use with my preferred form of tie-plate 1 preferably provide a rail having a flange wide enough to completely cover both the inner and the outer rail-rests. These plates are then placed upon a tie, and the rail-rests on the under surface thereon are forced into the tie, resulting in the breaking of the tie fibers at the edges of the rail-rests and also at the ends of the plate. These broken fibers usually stand at or near a vertical position, leaving a broken spongy mass of wood. At these points the extensions 15 and 18 obviously serve to cover the broken fibers at the outerand inn'er corners of the rail-rests, and the tapered ends 16 and 19 serve to cover the fibers at the ends of the plate, thus serving to protect the broken and spongy mass of wood, so that it will not easily rot or decay. Assuming that the rail has a flange just wide enough to cover the railrests; it is obvious that angle-bars may be placed on the rail and the spikes may be driven through the notches in the angle-bars and through the openings in the plate into the tie, and these spikes willrest against both edges of the rail, thus firmly holding the rail against lateral movement. Obviously this tie-plate may be readily inverted, and the upper surface will present a new wearing-surface to the rail. If it is desired to use a rail having a wider flange, the rail is placed in position, and the elongated spike-hole 20 provides means by which the inner spike may be set close against a rail of any ordinary width, and even though considerable wear has taken place on the railrests there will be no shoulders left upon the rail-rests at the edges of the rail, as would be the case if the rail rested upon a smooth-surfaced tie-plate. Furthermore, by thus providing two parallel longitudinal rail-rests with a comparatively wide channel between them the central portion of the rail-flange may spring downwardly when a heavy train passes over the rail, thus allowing a considerable elasticity or' spring in the rail itself without effecting or having any tendency to spring the tie-plate. I

In the modified form illustrated in the remaining figures of the drawings I have shown a tapered tie-plate having at its top a longitudinal rail-rest 21 near its outer end, and in the outer edge of said rail-rest is a rib 22, projecting upwardly above the rail-rests. the inner end of the tie-plate is a second railrest, 23, parallel with the first, and a channel 24 is provided between them. At the outer edge of the plate is an extension 25, in which the spike-opening 26 is provided, and on the inner edge of the plate is an extension 27, having a spike-opening 28 adjacent to the inner edge of rail-rest 23. The opposite surface of the tie-plate is smooth and flat, and the opposite surfaceof the extension is provided with alongitudinal rib 29 near its outer edge Near that is to say, beyond the spike-opening 26. The ends of this rib 29 are inclined inwardly toward the plate at 30, and near the central portion thereof is a transverse opening 21. In practical use with this form of my tie-plate and referring to Fig. 5 of the drawings it is obvious that the plate is attached for use under a rail-joint having angle-bars. When applied at the angle-bars, the plate is used with its flat surface uppermost, and in this position the outer edge of the angle-bar rests against rib 29, and the spike passes through the notches in the outer edge of the outer angle-bar and against the rail. Obviously these plates could be used on either one of the two parallel track rails and either of the rails would be inclined inwardly. Assuming that it is desired to use the tie-plates upon the rails proper without the angle-bars, I then invert the ti e-plate, so that the longitudinal rail-rests are uppermost in this position. The outer edge of the rail rests against shoulder 22, and the spike passes through the spike-hole 26 and engages the edge of the rail.
