RAlLWAY-TIE PLATE.

'useful Improvements in Railway-Tie Plates,

of which the following is a description.

Referring to the accompauying drawings,

' wherein like reference-letters indicate like or corresponding parts, Figure 1 is a partial perspeetive view showing my improved tie-plate in position upon a tie and with a rail resting thereon. Figs. 2, 3, and 4 are transverse sectional views of my improved tie-plate in line 2 2 of Fig. 1, showing steps in the method of forming the same. Fig. 5 is a modified form, and Fig. 6 is another modification.

The object of my invention is to produce a railway-tie plate ofsimple and economical Construction, which nay be readily engaged with the tie in a manner renderingaccidental disengagement dfficult, and which will also furnish an effective seat for the rail.

To this end my invention' consists in the novel Construction,combination,and arrangement of parts hei-ein shown and described, and more particularly pointed out in the claims.

In the preferred form shown in the drawings, A represents a metal plate of suitable size and material, which in passing through suitable mechanism, such as rollers, has formed upon one of its side surfaces, near the edges thereof, longitudinal ridges a. After having the ridges so formed the sides are turned downward by suitable mechanism until they form side flanges B, as shown in Fig. 4:, in which, in the preferred form, the ridges face inwardly, as shown. The lower edges of these flanges are drawn out to a point or sharpened, as it were, so that they may readily be forced into the wood of railway-ties. a The inclined surfaces of the ribs or shoulders permit the flanges to be readily driven into the tie, while the tops of the ribs, preferably extending substantially at right angles to the body of the fianges, prevent the easy or accidental disengagement of the same. The compressibility and elasticity of the material of which the tie is formed cause the material to conform elosely to the irregular surface of the fianges, as shown in Fig. 1.

accidental withdrawal of the ends of the fianges from the tie, and thus prevents the plate from buckling by reason of the Stress of the rail on the center of the plate.

If preferred, the ribs or ridges a may be formed on both sides of the plate, as shown in Fig. 5. In such case I prefer to offset the ridges on the opposite sides of the plate or flange, as shown, to prevent reducing the flange to such an extent as will weaken the same and render it more liable to break in use or in driving the same. In all cases I prefer to provide the fianges with a plurality of ribs or ridges a, thus securing a firmer connection of the plate with the tie. In the form shown in Fig. 6 the flanges are slightly fluted in a longitudinal direction for the same purpose as above set forth. In practice, however, I find the Construction first described more satisfactory.

By the term wooden tie in the 'claims I wish to be understood as including ties of wood or those eonstrueted of material possessing the qualities of penetrability, compressibility, and elasticity to an extent essential to the successful cooperation of the tie with the fianges of the plate, as described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A railway-tie plate comprising a metal plate provided with suitable spike-holes and with side fianges extending in the same direction from the plate-body substantially at right angles thereto and positioned to be at right augles to the rail, said fianges having formed thereon a plnrality of shoulders for preventing the accidental disengagement of the fianges from a tie composed of conpressible material inte which they may be driven, substantially as described.

2. A railway-tie plate comprising a metal plate provided with spike openings, side IOO fianges extending in the same direction from the piate-body substantially at right angles thereto and positioned to be at right angles to the rail, said fianges having one or more longitudinai ribs or ridges forned thereon, substantially as and for the purpose set forth.

3. A railway-tieplate comprising a metal plate provided With spike-openings and side fianges extending in the same direction from the plate-hody snhstantially at right angles thereto and arranged to be at right angles to the rail, said fianges having a plurality of lon gitudinal rihs or shoulders forned thereon, and also provided With spike-holes forned in the body of the plate, substantially as described.

4. A railway-tie plate eonprising a metal plate provided With side flanges extendng in the same direction substantially at right angles from the plate-body, said fianges having formed thereon one or more longitudinal ribs or ridges whose sides are inelined and whose shoulders extend at substantially a right angle from the face of the fiange, snbstantially as described.

5. A railway-te plote comprising a metal plate provided With side flanges extending in the same direction fron the plate-body substantially at right angles thereto, said fianges having one or more longitudinal ribs or shoulders formed 011 each side thereof, substantially as described.

G. A support for railway-rails eomprisin g a woode cross-tie in combination With a metal tie-plate provided with side fianges seated &32,895

longitudinaliy in the tie, said fianges extendin g in the same direction from the plate-body at substantiali y right angles thereto, and having formed thereon means for preventing the aocidental withdrawal of the same from the tie, and means for seeuring a rail in position upon the plate, substantially as described.

7. A metal tie-plate' eonsisting of a single plate having redueed and tapered edges, corrugated longitudinally to form securing projections in their under faces and bent down at an angle to the piate-body, substantially as described.

8. A tie-plate comprising a bed-plate, a sten, extending longitudinally and from the under face thereof, said stern having a cuttin g edge, longitudinal shoulders on each side thereof and longitudinal grooves between said shoulders and the plane of the under surface of said tie-plate, substantially as described.

9. A tie-plate comprising a bed-plate and a longitudinal stern or extended rib projecting below the same forned with longitudinal` seeuring ribs or shoulders on its opposite sides anda tapered point or edge, substantiaily as described.

10. A tie-plate comprising a bed-plate and a longitudinal sten below the same having a spear-shaped lower edge and retaining shoulders or projections on its opposite sides, substantially as described.
