A further object of the invent-ion is the provision of an improved tie plate/[which maybe l,used asa Splice connection for at` the top surface of oneside of a rail base flange., The overhanging flange 14:, in fact, f

Figure 1 is a -perspectiveviewof portion-.of a wooden tie, having the improved tie plate assembled in position thereon, a

3o rail section being` shown in dottedv linesjto demonstrate the relative position 'the same" will assume when connected;

Figure 3 is a longitudinal cross sectional view taken on the line 3 3 of Figure 1, and showing the manner in which the plate cooperates with a tie to prevent lateral shift- ,ino' of the same.

40 Figure 4 is a bottom plan view of the improved tie plate, showing the novel construction thereof. i

In the drawings, the letter A designates a tie, which'may be of wood or any approved material having the tie late B mounted thereon to receive a rail said tie plate B and rail C having the ordinary spikes D for secure attachment of the tie plate andk rail section to the tie.

The tie plate B includes the body plate 10, which is greater in length than the transverse dimension of the rail flange, and which feature has been provided in order that a portion of the body plate 10 may Aproject frorneach marginal edge ofr a rail base flange. vlt is preferred that the inside lmarginal edge`- 12 of the body portion 10` be less in thickness than'fthe thickness'of the portion ofy said body 10,'upon which the-rail j base rests, a bevelled upper surface 1.3 adjacent saidmarginal edge'p12 being provided` 'to facilitate entranceof the tie'plate B be-y neath a rail section C. Theadvantage in this formation can readily be seen, since therebythe body portion 10 of the tie plate flange of a rail sections a,

The 'outside part ofthe bodyvportion 10'is QB may be easily forced beneath the basekk provided with an overhanging fiange 14,"

preferably formed integral with the body portion 10, and which isy provided with the under flat surface 15 adapted for engaging forms a. rocket like' o enino` 16 for snuff the overhanging flange 14: being so formed as to engage the base flange of a rail section throughoutthe width of the tie plate B, the

' portion of a rail member C.' n c AThe bottom surface of the tie plate Bis of unusual formation, and is provided with the depending transverse ribs 25 upon the marginal edges of the plate B, and the dependingribs 26 upon the longitudinal marginaledges ofthe plate B. The intersect-v ing transverse ribs'28'and longitudinal ribs 29 are provided upon the bottom of said tie plate B, which cross each other substantially at right angles, and thusfproviding a. plurality of rectangular or polygonal shaped pockets ork depressions 30 extending upwardly from the bottom of the tie plate B, said depressions or pockets 30 being all of substantially the saine dimensions. It is preferred that the ribs 28 and 29 be substantially U-shaped in cross section, and whereby the extreme lowery surfaces 81 of said ribs are flat, having the sides 32 thereofl bevelling upward in diverging relation to 'the bottom surface 31, as is illustrated in Figures 2, 3, and 4L of the drawings. It can thus be seen that the pockets 30 decrease in size from their entrance, the marginal edges of said pockets 30 all converging upwardly. It is likewise preferred that the marginal depending ribs 25 and 26 have their inside edges bevelling upwardly similar to the sides 32 above described. n

The tie plate B is preferably provided with spike receiving apertures 2O and Q1 disposed transversely through the bony portion l() of said plate, said apertures being so positioned as to effectively retain the plate in conjunction with a rail. lt is preferred that these openings 20 and 2i be elongated and disposed in intersecting alignment with the longitudinal ribs 29, substantially as is illustrated in Figure fi of the drawing. Each of these slots 20 and 2l also includes a straight spike engaging surface which is, of course, disposed transversely of the plate i0.' For the opening 2l which is merely disposed tl'irough the thickness of the body portion l0, it is preferred that this straight portion 35 directly intersect through a transverse rib 28 for reinforcing purposes. In view of the fact that the opening :2O is partially disposed through the overhanging flange portion 14;, and at the juncture thereof with the body portion l0, the straight portion 35 of said opening 20 has ample reinforcing surface independent of extension of the same through a transverse rib 28. However, it is a feature of this invention that the apertures 20 and 2l are directly disposed at a point of intersection of a trans verse rib 28 with a longitudinal rib 29, so that the attaching spikes l) may have su'l'licient reinforcement insofar the tie plate is concerned. ln View of the fact that the longitudinal ribs 29 are disposed at right angles to the run of a rail C, and since the openings 20 andQl are directly disposed through said ribs 29, it can readily be understood that during attachment of the rail upon a tie plate, the said tie plate will not be liable to become chipped or split incident to the driving of the spike D therein,y since should the workman miss the spike D during driving of the same, the driving tool will hit the plate just above a. longitudinal rib 29, as can be understood. ln this manner, the plate B is constructed in the most favorablemanner for the effective recept-ion of rails.

rlhe advantage of providing the ribs Q5, 26,. 28 and 29 is apparent, since when the tie. plate B is disposed upon its tie A, the fibers of said tie A will swell upwardly into the pockets 30. ln lieu of the ordinary wood tie A, a composition tie may be provided with cert-ain intersecting channels. for the reception of the depending ribsof the `tie plate B. However, it is obvious that when the rails C are@ disposed in proper manner upon'the tie plates B, and after the rolling stock has settled thev tie plates B, the fibers will swell 'upwardly into the pockets 30. ln this manner, thel tie plates B will be more securely attached to the tie A, preventing any lateral creeping thereof, such as is ordinarily incident to wheel thrust and other exterior causes. ltcan readily be seen that it Will be almost impossible to shear off the bulging of the tie A which extend into the pockets 30. y v p From the foregoing, it is apparent'that tie plate hasbeen provided, which will be positioned upon a tie in a more secure relat-ion to seat the rail sect-ions thereon for maintaining aproper railway gauge.

Various changes in the shape, size and arrangement of parts, may ybe provided, without departing from the spirit of the 'invention or the scope' of the claim.

l claim:

As an article of manufacture, a tie plate for rails embodying a plurality of 'right angled intersecting longitudinal and trans. verse ribs, said platel having slots extending therethrough in direct intersecting align'-r ment with longitudinal ribs thereof, said slots having certain spike engaging surfaces thereon arranged in direct intersecting relation with transverse ribs thereof.
