RAILWAY-TIE PLATE.

Speciication of Letters latent.

Patented Dec. 21, 1920.

To all whoa t may concern:

Be it known that I, WARREN M. OsnoRN, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, having invented certain new and useful Improvements in Railway-Tie plates. for which I filed application for patent in the Dominion of Canada on March 22, 1920, Serial Number 239,053, do hereby declare that the following is a full, clearI` and exact description of the same,

My invention relates to railway tie plates.` its object being to provide new and irnproved means for utilizing the same plates for rails having bases of different or varying cross-sections or widths.

The invention consists of the matters hereinafter described and then pointed out in the claims.

In the drawings, Figure 1 is a cross-sectional view of the plate and an associated rail having a base of relatively small width with the spikes in the outer ends of the spike-holes and the spike-plugs between the spikes and rail-base, parts being in perspective and broken away for convenience of illustration;

Fig. 2 is a sectional view showing the same arrangement of parts as Fig. l and :in alternative form of plug;

Fig. 3 is a sectional view on the line t', I3 0f Fig. 1, and

Fig. 4 is a sectional view on the line irl of Fig. 2.

In the drawing the reference letter Av represents the head of a rail, B its base, and the web uniting the head and base.

The tie plate consists of the usual wily 5 provided near one side with an overhanging iiange 6 which extends the full length of the plate to engage the corresponding side of the rai] base, and with spiktI holes 7 outside the base of the flange to receive the spikes for that side of the plate. the flange preferably making a drive-lit with the rail base. The plate also is provided near its opposite side with an abutment S which is interrupted by the spike holes 9 to receive the usual spikes 10 which are driven into the underlying tie to assist in holding the }plate on the tie and the rail on the plate. ach spike hole 9 is preferably provided at its outer margin with a heelinglug 11 a ainst which the heel or back por tion of me spike abuts when the spike is driven to place, so that the spike is buttressed against the strains arising from the tendency of the rails to spread or tip sidewise, and the inner faces of the lugs 11 are inclined inwardly and downwardly. When the plate is not provided with the lugs the spikes bear against the outer ends of the holes.

The spike holes 9 are elongated in the cross-sectional line or width of the plate so that spikes may be driven through them into the underlying tie at different points or locations according to the differences in the width or cross-section of the rail base to hold it in position on the plate. The distance between the abutment 8 and the inner vertical wall of the flange 6 is suiiicient to accommodate the base of a large or heavy rail of any standard size or cross-section, say a 90 pound rail, and when such rail is in position its base fills the space between these opposite parts and the spikes for the holes 9 will pass through the outer portions of these holes and abut against the heeling lugs which wedge them against the ra il-base and with their heads overlying the rail base. When a rail is used having a narrower base, say a pound rail, the spikes for the holes 9 will be supplemented by spike-plugs 12 located between the spikes and the rail-base.

The spike-plugs 12 are individual pieces of metal adapted to be inserted in the elongated spike holes 9 and are of sufficient cross-sectional area to fill up the gap that otherwise would exist between a spike 10 and the rail-base, it being obvious that they will be made of different sizes in this respect so that such gaps of varying widths may be iilled according as the size of the rail base may vary. In the drawin for illustration, I show a spike-plug 12 a apted to fill the gap caused by the decrease 1n width of the base of a 65 pound rail in comparison with the width of a rail base that itself would fill the space between the parts 6 and 8. Preferably the spike-plugs interlock with the plate 5, and for this purpose each plug may be provided along the inner and lateral edges of its lower end with suitable langes 13 and 14, respectively, which rest in correspondingly countersunk portions of the inner and lateral walls of the lower ends of the spike holes. The inner ange may be omitted, as the side flanges lock the plug to the plate in effective manner. The plugs are inserted into the spike holes from below, and their flanges prevent them from being dislodged upwardly, While their lower ends are flush with the bottom of the plate and rest on the underlying tie, so that they are held against accidental displacement. The plugs are provided at their upper ends with inwardly directed Wings 15, which overlie the rail-base; When the spikes l() are driven to place the wedge action of the lugs 11 Causes the spikes to crowd the plugs against the rail base and to force the Wings dovvn upon the upper face of the base. Also, in the form shown in Figs. and 4 the inner wall of the body of the plug between its flange 13 and Wing 15 is recessed or cut back as shown at 16 to form a cross-channel eorrespoiuling in height to the end oi the rail-base and in which the end rests, thereby interlockin r the plug and base when the parts are assenibled. Tn both of' the forms Shown the rail cannot more up and down on the plate; even if the spike rises under the strains to which it is subjected by the traffic on the rail the plugl remains in its original and intended position as it is looked under the plate 5, and the rail remains in its corresponding position on the plate as it is interloeked between the plug and plate.

ln using the plugs they are placed in position in the splke-holes, after the rail base is positioned under the flange 6, and the spikes 10 are then driven to place, and are heeled up by the lugs and abut against the plugs to Wedge the rail base in place beneath the flange.

I claim:

l. A tie plate for rails comprising a body having elongated spike holes extending transversely thereof, a lug extending above the outer end of each hole to heel the spike therein, and spike-plugs fitting between the spikes and rail-base, each plug interlocking with its plate and having a Wing overlying the base.

2. A tie plate for rails comprising a body having elongated spike holes extending transversely thereof to receive a spike in the outer end of' each hole, and a spike-plug tting between the rail-base and the spike and having a Wing overlying the base and a cross-channel to receive the base, the lower end of the plug being Hanged, and the lower end of' the spike-hole being countersunk to interlock therewith.

3. A tie plate for rails comprising a body, an overhanging flange to engage one side of the rail base, the body having elongated spike holes extending transversely thereof, a lug extending above the outer end of each hole to heel the spike therein, and a spikeplug lifting between the rail-base and the spike and having a wing overlying the base, the lower end of the plug having lateral flanges, and the lower end of' the spike-hole being couutersunk to receive the flanges.

ln testimony whereof I afiix my signature in the presence of' two witnesses.
