Referring to the (lrmvings:1 designates a tie plate embodying my invention, the

adopted to be interposed between tht; rail 2 and. the lie 3. The upper surface 4 of the tie plate is provided with a shoulder 5 and against which the flange of the rail 2 is adapted to abut. The upper surface 1 preferably inclines or tapers toward the side-6 and in proximity to the side 6 the upper surface is beveled or inclined as indicated at 7.

s designates proportionately wide channels or grooves on the upper surface 4 of the tie plate which begin in proximity to and extend completely across the plate to the side 6 and these channels or grooves 8 preferably incline or slope toward the. face 6 of the plate so that. or other deleterious material will be drained oil, thereby preventing the accumulation of water or other foreign material between the engaging surfaces of the tie plate and the rail.

J designates spike holes one of which is loouted der 5 so that the strain or sheer on the spike will be reduced to u minimhm and theothcr spike hole is referably located as most t-leurlvseeu' in *ig. 2, near the beginning of the beveled or inclined portion 7 of the top surface 4. The under surface Jlate is provided with tra nsversely extendin l anges 10 and 11, the. flange 10 being locate in proximity to the-s ike hole-'9 an preferably runnin paralle with the shou while the thing-e 11 is preferably parallel with the flange 10 and locatedin proximity to the snilje hole on the opposite side of the'plate.

12 designates a flange iocated intermediutely of the flanges 10 and 11, it being noted that the flange IQ is shorter. than the flanges 1.0 and 11 and ll of the in es, 10, 11 and 12, are preferably made wedge sha e in order that theywill piorc easilyenter't'lie fibers of the wood of the tie 3.

13', 14 and 15 designategongitudinally ex-v tending ribs or lu s locate ont-heundersurface of the tie pate 4 referably arranged pnrtllel to each eing noted that the 11; while the rib ll iis'loca'tedin proximity to a longitudinal plane at the end of the interwater. sand of the tie der 5,

to a plane passextending across the tie plate mediate transverse'fianqe-H,while the rib 14 to. l? and 18 designate ribs located between the flanges 10 and 12 and preferably arraiiged parallel with each other, the rib 17 being located intermediately of the ribs 16 and 18, the. rib 18 being located in a longitudinal plane passing in proximity to the end of the tlanges l0 and 11 and located on the opposite side of the tie plate from the rib 13, while the rib it) is located in a longitudinal plane in proximity to the end of the central trans-terse plane 12 and is located on the opposite side' from the rib lb, said ribs l-l to IR being arranged in staggered order with respect to each other, and being preterably wedge shaped and rounded as is indirated in l igst l and il. lt will be seen that by such an arrrurgemeut and disposition of the ribs '13, ll, 15, 16, 17 and 18 and the llang es it), It and 12, such ribs and 'tlanges are 0- eated oat the under side of the rail tie directly beneath the rail so that the weight of the rail and the trallio thereover will cause such ribs to become firmly embedded in the fiber of the tie so that any late a1 or longitudinal movementof the tie with respeet to the tie plate will be positively prevented. It will be evident that after the tie plate is once spiked in place it will be necessary for the whole tie to be removed in order to change the position of the tie plate with respect to' the rail. I

The location of the channels 8 is such that the wate and other deleterious material will be drained from the tie plate and at the same time owing to the location of these channels and the location and arrangement of the ribs and flanges on the under surface of the rail,

the tie plate will have the requisite struc- .tural strength without increasing the amount of material and it has been found in practice that a tie plate embodying my invention can be readily and chea )lymanufactured and i very durable under heavy tratlir.

it is to be noted that in my present eon- 5,st ructiou. the tlaue'es to. it and l) and the rail abnttin' shoulder 5 extends transversely of the tie wllile the lugs on the lower surface of the tie plate extend lmie'itudinally ot the tie.

It will now be apparent that l have de vised a novel and useful (construction of a tie plate which embodies the Features enu-- inerated as desirable in the foregoing, and while I have. in the present instance, shown and described a preferred embodiment there of which in practice gives satisfactor i and reliable results, it is to be understood that the sameis suseentible or" modification in t an angle to sa d shoulder, the lower sui various particulars without departing ron] the spirit and scope of the invention or sacritieing any of its advantages.

Having thus described my invention, '-.'ll1'.l, l claim as no and desire to secure by tors Patent, is
