RAILWAY TIE PLATE.

No. 535,963. Patented Mar. 19, 1895..

U ITED STATES PA ENT ()FFICE.

JAMES T. STEWART, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE SHOULDER TIE PLATE COMPANY, OF NEW JERSEY.

RAl LWAY-Tl E PLATE.

SPECIFICATION forming part of Letters Patent No. 535,963, dated March 19,1895.

Application filed July 11, l 8 9 2 My invention relates to railway tie plates and consists of certain improvements which are fully set forth in the following specifica- .10 tion and are shown in the accompanying drawings, which form a part thereof.

More particularly my invention relates to metallic tie plates which are designed to be arranged between the wooden ties and the rail to relieve the wooden ties of the wear due to the direct action of the rail upon them. Such plates may also serve to brace rails and hold them in place and to relieve the strain from the rail spikes. In tie plates of this kind the great strain upon the central or rail bearing portion due to the downward pressure of the rails from the passage of railway trains tends to cause the outer portions which extend beyond the rail to bend or turn upward; and

myinvention is designed to overcome this defeet by strengthening the plate at these parts by means of diagonal ribs which may be formed upon the under surface of the plate and may be driven into the wood of the tie so as to more firmly hold the plate in place and relieve the fastening spikes of strain.

The particular construction of the tie plate in other respectsis not material to my invention. In the accompanying drawings, how

ever, for purposes of illustration I have shown a tie plate of the general construction shown in Letters Patent of the United States to Louis Blackstone, No.413,609, dated October 22, 1889.

In the drawings:-Figure 1 is a perspective View of a portion of a railway tie, rail and tie plate. Fig. 2 is a transverse sectional view of the same on the line 00- 0:: of Fig. 1. Fig. 3 is an inverted plan view of a tie plate embodyingmyinvention. Fig.4isaperspective view of the same with the plate inverted; and Fig. 5 is an inverted plan view of a tie plate illustrating a modification of the invention.

A is the wooden tie.

B is the rail.

O is the tie plate which, may have upon it Serial No. 439,625- (No model.)

upper surface one or more brace pieces 0 adaptedto bear against the flange of the rail to receive the side thrust. These brace pieces c may be arranged upon either or both sides.

D are rail spikes which may be driven into the tie through slightly offset spike holes d so as to relieve the spikes of side thrust.

E are fastening spikes for securing the plate 0 to the tie.

F are ribs upon the tie plate extending diagonally across the portion of the plate which extends beyond the part which receives the rail base. These diagonal ribs maybe continued entirely across the plate as shown in dotted lines in Fig. 3, but their presence under the part which receives the rail base is not necessary. I prefer to arrange these ribs F as shown in Fig. 4 upon the under side of the plate running from the corners toward the center. A different arrangement is shown in Fig. 5.

The number of diagonal ribs employed is not essential. One or more may be used. The

diagonal arrangement of the ribs serves to' strengthen the plate throughout and effectively prevents the turning up or bending of the sides. As the ribs extend diagonally it will .be seen that they brace the plate both longitudinally and transversely, not only preventing the bending of the sides in a longitudinal. direction, but also preventing the turning up of the corners of the plate. The plate is thus preferably braced with a minimum expenditure of metal for the purpose. By employing these ribs it is possible to em ploy much lighter plates than could otherwise be used so that a great saving of metal is obtained.

When the ribs are located upon the under side of the plate they may be buried in the wood of the tie as is shown in Fig. 2, thus serving also to hold the plate in place and relieve ceive the rail base provided upon its under surface with a diagonal strengthening rib extending diagonally beyond the portion which receives the rail base up to the outer edge of the plate.

5 2. A railway tie wear plate adapted to receive the rail base provided upon its under surface on each side with a diagonal strengthening rib extending diagonally beyond the portion which receives the rail base up to the 10 outer edges of the plate on each side.

3. A railway tie wear plate adapted to receive the rail base having its under surface provided upon each side with ribs extending diagonally across the plate on either side he- I 5 yond the rail spike holes.
