UNITED STATES ROBERT A. BRADLEY, OF MERRITTON, ONTARIO, CANADA.

RAIL TIE PLATE.

Original application filed October 8, 1925, Serial No. 61.347, and in Canada April 23, 1926.

1,593,423, dated July 20, 1926. Divided and this application filed May 10, 1926.

This invention relates to an improvement in tie plates and the present application is a division of my co-pending application for rail. tie plates, filed October 8, 1925, Serial No. 61.347, Patent 1,593,423, granted July 20. 1926.

The object of the invention is to provide a tie plate ot' simple. durable and comparatively inexpensive construction and which is adapted to be organized with the tie in such manner as to resolve the pull on the rail spike (due to undulation caused by passing train or in any other way) into a lateral pull instead of the usual vertical pull. words the forces tending to pull the tie plate away from the tie are exerted transversely oi the spikes and are resisted by the solid cross section of spike and tie and are not applied to the spike in such a way as to tend to pull the spike from the tie.

A further object is to combine with the tie plate an anti-creep device or wedge in a simple and practical yet highly effective manner.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will. be hereinafter more fully de scribed and particularly pointed out in the appended claim, reference being had to the accompanying drawings forming a part of this specification, and in which:

Figure l is a fragmentary plan view of a blank from which the tie plates are formed;

Figure 2 a plan view of a tie plate;

Figure 3 is a fragmentary perspective view showing the tie plates associated with the rails and ties;

Figure 4 is a perspective view of the anticreep wedge employed; and

Figure 5 is a similar view of type spike.

Referring to the drawings and more especially to Figure 1 the numeral 1 designates a blank from which the tie plates designated generally at 2 are formed, the plates 2 being cut from the blank along the lines shown.

Each tie plate 2 has a body portion 3 on the bottom of which ribs 4 are formed. The ribs 4 are adapted to be embedded in the tie to prevent transverse movement of the plate on the tie. On the top of the body portion the special In other Patent No. Serial No. 103,146.

a curved flange 5 is formed and is adapted to engage over one edge of the rail base. Spike receiving openings 6 are also formed in the body portion. Either ordinary spikes or spikes 7 having grooved heads 8 may be employed and as shown in Fig. 3, the spikes driven through the openings 6 are engaged with the edge of the rail base opposite the edge thereof engaged by the flange 5. The grooved heads 8 facilitate removal of the spikes. The openings 6 may be provided at diilerent distances from the flange 5 to adapt the plate for use with rails having bases of difierent width. At diagonally opposite corners of the body portion wings 10 are integrally formed with the plate and are adapted to be extended down along the sides of the tie so that spikes 11 may be driven horizontally into the tie through openings 19. in the wings. These spikes 1.1 take the vertical pull exerted on the tie plate by the rmdulations caused by passing trains and such pull being exerted transversely of the spikes 11 is effectively resisted. The plates are constructed of metal having sufficient resiliency, bendability or flexibility to permit the wings to be bent down along the sides of the tie.

An anti-creep wedge shown at TV in Figure -l may be employed and when user. is driven in between the base of the rail and the overlying rail base engaging flange 5. The flange 5 is made of such size as to be adapted to be snugly fitted against the upper face of the rail base, or it is of such size as to engage the anti-creep wedge thereon or a rail splice if the latter be employed.

I claim:

A tie plate having a substantially rectangular body portion adapted to fit on the top out the tie-and wings integral with the bony portion and located at diagonally opposite corners of the body portion and uniformly offset laterally for their entire extent from the sides thereof, said wings being adapted to be secured to the tie by horizontally extending" spikes, the body portion having an upstanding rail securing flange extending along and inwardly spaced from one side and also having spike receiving openings along and inwardly spaced from its other side.
