c. T. MATTHEWS ET AL TIE PLATE Filed May 19, 195 0 III r J z HK Mallhews ww Patented Jan. 5, 1932 res PATENT o-FFicE CARLTON T. MATTHEWS AND HARQLD K. .I'IATTHEWS, 0F GREEN BAY, VJ'ISGGNSIN TIE PLATE Application filed. May 19,

This invention relates to tie plates and one object of the invention is to provide a plate adapted to rest upon a tie beneatlra rail in order to serve as a support for the rail, the under face of the plate being so formed that the weight of the rail will cause portions of the plate to bite into the tie and prevent the plate from having movement transversely or longitudinally of the tie. 7

Another object of the invention is to so form the upper face of the plate that a rail secured thereon will be pitched inwardly a slight extent and thereby reduce likelihood of a rail spreading or the wheels of a train jumping the track.

Another object of the invention is to pro vide the plate with improved means for securing a rail thereon including cleats for engaging opposite side portions of a rail base and a filler strip adapted to be disposed between the rail base and one cleat and held in place by heads of spikes employed to secure the rail and plate in place.

Another object of the invention is to so form the tie plate and rail-engaging means that a rail may be easily and quickly set in place or removed and very firmly secured when fastened to the plate.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view showing the improved tie plate in use,

Fig. 2 is a view showing the rail and tie plate in elevation,

Fig. 3 is a sectional view taken on the line 33 of Fig. 2, and

Fig. 4 is a bottom plan View of the tie plate.

The improved tie plate, indicated in general by the numeral 1, may be formed of steel or any other desired metal and is of sufficient length and width to rest upon a tie 2 with end portions of the plate projecting from opposite sides of the base 3 of a rail 4:- The under face of the plate is formed with end recesses 5 and intermediate recesses 6 which extend longitudinally of the plate in alinement with each other, and it should be noted that the ends of the intermediate recesses terminate in spaced relation to the 1930. Serial 'No. 453,828.

'has'firm engagement with the upper face of 69 the tie but at the same time the weight of the'rail will cause the edges of the ribs 7 and .8 to bite into the tie and prevent the plate from moving upon the tie. Therefore,

the rails will be prevented from creeping and also prevented from spreading. One of the transversely extending ribs 7 is disposed a shorter distance from the adjacent end of the plate than the other transverse rib and attention is called to the fact that the upper face of the plate slopes from directly above 'thelast-mentioned rib towards the opposite end of the plate. This is clearly shown in Figure 3, and referring to this figure it will be seen'that, when the rail is set in place upon the plate, it will be disposed .slightly out of-a perpendicular position and lean inwardly. By this arrangement force exerted as a train passes over a track will 'be'less likely to cause the rails to spread.

- In order to secure the rail in place, there have been provided cleats 9 and 10 formed integral with the plate and extending upwardly therefrom in such spaced relation to each other that the inwardly extending flangesll and12 of the cleats may overlap sideportions of the rail base. The flange 12 of the cleat 10 is of greater length than the flange of the cleat 9, and it should be noted that the distance between the inner faces of these cleats is slightly greater than the width of the rail base. Therefore, when the rail is set in place upon a plate, it maybe first engaged beneath the flange of the cleat '10 and then moved into position for the other side edge of its base to bear against the inner face of the cleat 9 with the flange 11 overlapping the rail base. After the rail has been moved into engagement with the cleat 9, a filler strip 13 is driven into place between the cleat 10 and adjacent edge of the rail base, and this strip not only bears against the side edge of the rail base but also overlaps the rail base and fills the space between the rail base and the under face of the flange 12. formed through the plate in spaced relation to each other longitudinally of the transversely extending ribs 7 and it should be noted that these openings are disposed at opposite sides of the cleats in spaced relation thereto. filler strip 13 is of suficient length to project from opposite sides of the cleat 10 but of such length that, when it is in place, its ends terminate in spaced relation to the openings. Therefore, when spikes 15 are driven through the openings into the tie with their heads 16 overlapping and bearing against the rail base, the portions of the spike heads which project transversely, as shown in Figure 2, will bear against ends of the filler strip, as clearly shown in this figure and prevent the filler .strip from slipping longitudinally out of place. It will thus be seen that the spikes not only serve to secure the plate and rail in place but also constitute means to retain the filler stripin place. If, for any reason, it is necessary to remove a rail, it is merely necessary to extract the spikes at opposite sides of the cleat 10 and the filler strip can be easily driven out of place, thereby releasing the rail and permitting it to be easily and quickly lifted from the platewithout entirely releasing the plate from the tie.

Having thus described the invention, We claim: 7

A tie plate, openings being formed in'the plate to receive securing spikes, rail-engaging cleats extending upwardly from the plate between sets of spike receiving openings and having flanges extending towards each other to engage over side portions of a rail base, the cleats being spaced from each other a distance greater than the width of a rail base and one cleat being disposed in spaced relation to spike receiving openings between which it is located, and a filler strip driven into place beneath the last-mentioned cleat to engage a rail base, the filler being of less length than the distance between the openings'at opposite sides of the cleat beneath which the filler extends, but of suflicient length to have its ends engaged by side edges of the heads of spikes driven through the openings into a tie, whereby the heads of the spikes may engage the filler and serve to hold the filler against slipping longitudinally out of position after being driven tightly into place.

In testimony whereof we affix our signatures. V CARLTON T. MATTHEWS. [L.S.] HAROLD K. MATTHEWS. [1 s] Openings 14 are It should also be noted that the
