TIE -PLATE Application filed. June 13,

To all whom it may concern:

Be it known that I, FRANK A. PIPER, a citizen of the United States, and a resident of Redlands, in the county of San Bernardino and State of California, have invented a new and Improved T iePlate, of which the following is a full, clear, and exact description.

This invention relates to railway tie plates, and more particularly to that class of tie plates which serves to support rails upon the tie and at the same time to prevent the spreading of the rails.

The object of the invention is to provide a simple, strong and inexpensive tie plate, formed preferably from sheet metal, and having at the ends shoulders to engage the outer edges of the rail bases.

A further object of the invention is to pro vide a tie plate having rail-engaging shoulders near the ends, openings for the passage of spikes at both sides of the rail, and laterally-disposed flanges constituting spurs to be forced into the tie to secure the tie plate thereupon.

A still further object of the invention is to provide a tie plate having a portion folded upon itself at the end, to constitute a shoulder for engaging with the outer edge of the rail base, and having an opening through the plate at the shoulder for the passage of a spike to engage the rail whereby the spike at the outer edge engages a double thickness of metal.

The invention consists in the construction and combination of parts to be more particularly described hereinafter and fully set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which Figure 1 shows. a section of track with my tie plate applied thereto; Fig. 2 is a transverse section of the same; Fig. 3 is a perspective view showing the end of the tie plate; Fig. 4 is a perspective view showing the under side of the end of a tie plate; and Fig. 5 is a perspective view of the end of a modified form of tie plate.

Referring more particularly to the drawings, 1 represents a cross-tie, of wood, of the usual kind employed in railway track construction. Mounted upon each cross-tie 1 Patented Oct. 27', 1908.

1907. Serial No. 378,766,

is a tie-plate of my invention, having an elon gated body portion 2 extending substantially from one track-rail 3 to the opposite parallel track-rail. Near the ends, the tieplate is arranged under the track rails and supports the same. The end or bearing portions 4 of the tie-plate are laterally extended to present a wider bearing surface for the rail base. The ends of the tie-plate are folded back upon the body to form shoulders 5, for engaging the outer edges of the rail bases to prevent outward movement of the rails upon the tie-plate. Openings 6 are formed in the tie-plate near the ends for the passage of the spikes 11, used ordinarily for holding the track-rails in position, and serving to hold the rails upon the tie-plates against upward displacement. The inner edges of the openings 6 are flush with the inner edge of the shoulder, the openings being arranged underneath the shoulder. Each shoulder 5 has at the inner edge, recesses 7 registering with the openings 6 of the tie-plate. In this way the opening through the tie-plate has walls of double thickness at the sides and at the outer face; consequently, the spike has a surface of double width to bear against in resisting the outward movement of the rail, and thereby the danger of shearing off the spikes-due to lateral pressure upon the railis minimized. The extended portions 4 of each tie plate have further spike openings 8 therethrough, located inwardly from the shoulder 5. The openings 8 receive the spikes 12, to engage the inner edge of the rail base and hold the rail against inward lateral movement.

The extended portions 4 of the tie plates serve as bearing members for the rails, and are fashioned by suitably bending or folding the blanks from which the tie plates are made. In the blanks each of the extended ortions 4 has at the opposite lateral edges, ,fiat V-shaped indentations 9. The side edges of the indentations 9 are downwardly disposed to form spurs 10, the edges of which are preferably sharpened. The spurs 10 have sharp apeXes 13 and are formed by bending the blank along lines running from the'apeXes 9 of the recesses to points 141 which represent the corners of the bearing ortions when the tie plate is completed. The lines of plicature from the apexes of the l indentations to the points 14 run somewhat inwardly toward the center of the tie plate whereby the inclination of the edges of the spurs is increased as is shown most clearly in Figs. 2 and 3. It will be understood that the points 14 lie inwardly from the corners 13 of the blank which subsequently become the apeXes of the spurs. The spurs 10 adjacent to the outer ends of the tie plate include the folded over part constituting the shoulder, whereby these outer spurs are stiffened and strengthened.

In Fig. 5 is shown a modified form of tie plate, in which the lateral edges are not indented and in which there is but a single spur at each edge, formed by bending over a substantially rectangular portion of the plate. I prefer the mutually inclined spurs at each edge, as shown in the form illustrated in the other figures of the drawing, as these spurs more strongly resist lateral pressure upon the tie-plate.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent 1. A tie-plate having an end folded upon itself to form a shoulder to engage the outer edge of the rail base, an opening located inwardly from said shoulder for the passage of a spike to engage the inner edge of the rail base, and a laterally located and downwardly disposed portion including a part of said folded end and constituting a spur for engaging a tie.

2. A tie-plate having an end folded upon itself to form a shoulder to engage the outer edge of the rail base and having an opening therethrough under said folded portion to re ceive a spike, said folded portion having a recess registering with said opening, whereby the opening through the tie-plate has a face of double thickness at the outer edge, and a laterally located and downwardly disposed portion including a part of said folded end and constituting a spur for engaging a tie.

3. A tie-plate having an end folded upon itself to form a shoulder to engage the outer edge of the rail base, an opening located inwardly of said shoulder for the passage of a spike to engage the inner edge of the rail base, and an opening having the inner edge flush with the inner edge of said shoulder, for the passage of a spike to engage the outer edge of the rail base, said shoulder having a recess at the inner edge registering with said open ing under said shoulder, and a laterally lo cated and downwardly disposed portion including a part of said folded end and constituting a spur for engaging a tie.

4. A tie-plate having an end folded upon itself to form a shoulder to engage the outer edge of the rail base, and presenting an indentation at a lateral edge, said tie-plate being laterally located and downwardly dispos'ed adjacent to said indentation and including a part of said folded end to form spurs to engage a tie.

5. A tie-plate having an end folded upon itself to form a shoulder to engage the outer edge of the rail base, and presenting projections at the lateral edges, said tie plate having portions adjacent to said'projections and including a part of said folded end downwardly disposed to constitute spurs to engage a tie, the line of the bend of each downwardly disposed portion being at an angle with the line of the bend of the adjacent portion.

6. A tie-plate having an end folded upon itself to form a shoulder to engage the outer edge of the rail base, an opening located inwardly from said shoulder for the passage of a spike to engage the inner edge of the rail base, an opening having the inner edge flush with the inner edge of said shoulder, said shoulder having a recess registering with said opening adjacent to said shoulder, and projections at the lateral edges of said tie plate, the portions of said tie-plate adjacent to said projections and including parts of said folded end being downwardly disposed to constitute spurs to engage a railway tie, the spurs at each lateral edge being mutually inclined.

7. A tie plate, comprising a body adapted to be arranged upon a tie and to extend from rail to rail of a track, and bearing portions rigid with said body and adapted to be arranged under the rails, said bearing portions having the ends folded upon themselves to form shoulders to engage the outer edges of the rail bases, and having openings located inwardly from said shoulders for the passage of spikes which engage the inner edges of the rail bases, said bearing portions having laterally located and downwardly disposed parts each including a part of said folded ends and each constituting a spur for engaging a tie.

8. A tie plate, comprising a body adapted to be arranged upon a tie and to extend from rail to rail of a track, and bearing portions integral with said body and adapted to be arranged under the rails, said bearing portions having the ends folded upon themselves to form shoulders which engage the outer edges of the rail bases, openings located inwardly from said shoulders for the passage of spikes which engage the inner edges of the rail bases, and laterally located and downwardly disposed portions including parts of said folded ends and constituting spurs for engaging a tie.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANK A. PIPER.
