WEAR-PLATE FOR RAILWAYETIES.

Be it known that I, SIMON CLARY, a citizen of the United States, residin at Carnegie, in the county of Allegheny all? State of'Penn- 'sylvania, have invented a certain new and useful Improvement in Wear-Plates for Railway-Ties, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention metal Wear plates for railway ties, and has for its object to provide a plate of this character which shall be sim le and economical of production, and one wl fich shall be so constructed that, when installed in lace between the bottom flange of a rail and the subprevent the creeping of the rails and will also practically eliminate the shearing of the s ikes by the thrust of the rail flanges either directly or indirectly thereagainst.

Generally speaking, the invention may be defined as consisting of the combinations of elements embodied in the claims hereto annexed and illustrated in the drawings forming part hereof, wherein Flgure 1 represents a perspective view showing my p ate applied to a rail; Fi 2 represents an end elevation of said p ate with parts broken away to show the arran ement of one of the laterally extending r1bs with reference to the corresponding spike hole; and Fig. 3 representsa top plan View of said plate.

Describing the parts by reference characters, 1 denotes a rail to which my late is applied, the plate bein substantlal l tangular in outline and fleing provided with a central flat rail-receiving portion 2 bounded at opposite edges thereof by upwardly extendlng shoulders-3 and having on its under side a pair of downwardl" extending ribs 4. The shoulders and ribs are shown as extending the full width of the plate.

As will ap ear from the drawing, the inner faces 3 of t e shoulders are abrupt or vertical and, from the'upper ends of said shoulders the plate diminishes gradually in thickness toward its outer edges. The under surface of the plate comprises two flat or plane portions 5 each extending inwardly from the outer edge of the plate beyond a rib 4, the central under surface of the plate being recessed at 6.

As will appear more particularly from Figs. 2 and 3, the ribs 4 are located just within or Specification of Letters Patent. Application filed January 11, 1908. Serial No. 410,332.

toward the center of the plate from the shoulders 3 and are each provided'with a tapered edge 4" to facilitate the insertion of the rib into a tie, and with an outer vertical face 4, which forms, in effect, an extension of the vertical inner face of the shoulder 3. Each shoulder is provided with a spike hole 7 mter osed between the lon itudinal center all an end of'the shoulder, t e spike holes in the two shoulders being diagonally op osite each other. As shown, this spike ho e extends entirely through the inner vertlcal face of each shoulder and, in the constructlon of the plate, the vertical faces4 of the I'lbS 4 are inset very slightly with reference to the nner vertical faces of the shoulders so as to 1nsure that the tool which is em loyed for punching the spike holes througlthe late will cut through the inner face of each s oulder and will ust clear the outer vertlcal face of each rib. The outer face of each rib forms, in effect, a continuation of the inner face or wall of the spike hole.

The advantages of a plate constructed as described are as follows:

1. The provision of the two shoulders se cures the proper facing of the plates on the rails and on the ties, as the space between the shoulders is substantially the width of the bottom flange of the rail, whereby the shoulders will be parallel with the edges of the rail flanges and in substantlal contact therewith throughout the width of the plate.

2. The provision of the two shoulders prevents the creeping of the rails as, should the tie tend to twlst in either direction, the rall flange will be gripped by the opposlte ends of the shoulders respectively.

7 3. The location and construction of the ribs increases the bearing surfaces of the spikes, whereby liability to shear off the s ikes by the thrust of the plate 1s practically e iminated. The inner face of each s ke will bear not only against 'the metal of w lch the body of the plate is composed but also against the vertical face 4 of each rib. Whilethe vertical faces 4", for the purposes of my invention constitute an extension of the vertical inner faces of the shoulders thereabove, the slight inset given to the outer faces of these ribs with reference to said shoulder accommodates the slight variations in wldth which occur in the flanges of standard rails of the same weight.

4. The construction and arrangement of the ribs also provide guides for the spikes which keep them straight while being driven the plate, each rib being provided with a vertically extending surface forming a continuation of one of the faces of the corresponding spike aperture.

2. A wear plate for railways having spike apertures extending therethrough and having a plurality of ribs on its under surface said ribs extending continuously across the late transverse to the grain of the tie and aving a vertically extending 'outer face forming a continuation of the inner face or Wall of said spike aperture.

3. A. wear plate for railways having a air of ribs on its under surface and exten ing transversely thereof, each of said ribs having a vertically extending outer surface along the entire length of the rib said plate having spike holes extending therethrough and each having its inner face in substantial vertical alinement with the vertically extending surface of a rib.

4. A wear plate for railways having on its upper face a pair of transversely extending shoulders, each shoulder having an inner vertical face, a pair of ribs on the under surface of said plate, each rib having an outer vertically extending surface in substantial alinement with the inner vertical face of a shoulder, said plate being provided with a spike hole extending through each shoulder, each s ike hole extending through the inner face 0 a shoulder and having its inner face or wall forming in effect a continuation of the vertical outer surface of the subjacent rib.

5. A wear plate for railways having on its upper face a transversely extending shoulder,

said shoulder having an inner vertical face, a

rib on the under surface of said plate, said rib having an outer vertically extending surface in substantial alinenient with the inner vertical face of said shoulder, said plate being provided with a spike hole extending through said shoulder, said spike hole extending through the inner face of the shoulder and having its inner face or wall forming in eflect a continuation of the vertical outer surface of the subjacent rib.

6. A wear plate for railways having on its under surface a transversely extending rib, said rib being provided with a vertical sur face, said plate having a shoulder on its upper surface in substantial alinement with the vertical surface of the subjacent rib, said shoulder having a spike hole extending therethrough and through the inner face thereof, the inner face or wall of said spike hole being in substantial alinelnent with the said ver tical surface of the subjacent rib. W

7. A. wear plate for railways having a s ike aperture therethrough, a projection on tile under surface of the plate, said projection extending past the aperture and having a vertically extending surface that forms substantially a continuation of the inner face of the spike aperture.

In testimony whereof, I hereunto affix my signature in the presence of two witnesses.
