TELE PLATE.

Application filed .March To all whom t may coi/cern Be it known that l, AeosriNo Liften, a citi-k zen of the United States, residing at Clearu creek, inthe county of Carbon and State of Utah, have invented certain new and useful improvements in a flie Plate, of which the following is a specification.

My invention relates to new and useful improvements in tie -plates adapted `to be interposed between the base of the rails and the upper surface of the ties, the principal object of the invention being to generally improve the present tie plate in both strength and durability and also the execution of the necessary functions.

An important object of the invention is to provide the tie plate with means for increasing its adhesion to the tie to prevent rails from creeping laterally and longitudinally with relation to the tie.

Other objects and advantages of the invention will become apparent during the course of the following description.

ln the accompanying drawings forming a part of the. application and wherein like numerals are employed to designate like parts throughout the several views.

Figure l is a. top elevation of the invention,

Figure 2 is a bottom plan of the salme,

Figure 3 is a side elevation of the saine,

Figure l is a longitudinal section through the device, a rail and spikes being illustrated in position thereon.

ln the accompanyingl drawings, wherein is illustrated a preferred embodiment of the invention, a fragment of a rail section is indicated by the numeral 5 in F l and et. For the purpose of clearness, the longitudt nal edges of my improved tie plate are indicated by the numeral 6 while its transverse edges are designated by the numeral 7. The longitudinal edges 6 of the plate. extend longitudinally of the cross tie 8 shown in Fig. Ll.

The upper face of the tie plate is inclined as shown at 9, the thickest portion of the plate being adjacent the vouter side of the rail. transversely extending rib 10 is formed upon the highest part of the upper face7 its inner side being vertical to engage the outer edge of the rail base to prevent the rail from creeping outwardly upon the plate. rFhe outer edge of this rib 'is inclined outwardly and merges into an outwardly and downwardly inclined portion 11. A plurality of grooves l2 are provided in this lt). Serial No. 368,314.

inclined portioull and extend longitudinally. Thebottom of thesewgrooves as well of the plate.

ln the inclined upper face 9 a plurality of transversely en ending channels 13 are provided, it being noted that these channels are y adapted to be disposed under the under facey of the rail base, as most clearly shown in Fig. Il. The channels extend entirely across the plate to meet t-he longitudinal edges thereof.

A pair of spaced openings are provided to extend through the rib l0 to receive the usual spikes l5, the heads of which engage over the edge of the rail base for securing the rail to the plate. A pair of spaced openings 16 are. also provided at the opposite side of the plate to receive spikes l5 which engage the opposite edge of the rail base for a purpose well known.

As most clearly shown in Figs. 2 and 4;,

kthe lower face of my improved tie plate is flat is provided with a plurality of spaced transversely extending ribs 17. It is to be particularly noted that the longitudinal sides of the ribs are parallel to each other and are `perpendicular to the bottom of the plate. However, the lower edge of the inner side of each rib is removed and inclined as shown by the numeral 18 whereby each rib is provided with a lower penetrating edge. This particular construction `of the ribs is designed to resist lateral creep' ing of the tie plate with relation to the rails as it is well known that it is the normal tendency of such plates to move in this direction. However, this movement is restricted by the outer fiat sides of the ribs being forced against abrupt shoulders formed in the tie by the ribs entering the same. It is also apparent that there is less possibility of the wood tie acting upon the ribs to wedge them from their retaining grips. It is further to be noted that the two adjacent ribs 17 arranged nearest the thickest portion of the plate are disposed upon opposite sides of the spike openings 14. 'llhere` fore, these two ribs prevent moisture, sand and the like from creeping under the plate towards the spikes and acting thereon to loosen the same.

The lower outside edge of the plate is equipped with a cut away portion 19 in order that a suitable implement may engage under the plate to loosen the same when desired.

The foregoing description and accom panyingdrawings have reference to what might be considered to be the approvedor preferred form of my invention. I desire it to be understood that I may make such changes in construction, combination and arrangement of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claim.

Having thus fully described my invention what I claim as new and desire to secure by i; Letters Patent, is

As a new article of manufacture, a tie plate comprising a body tapering 1n thickness from its larger outer end to `its inner end, transverse rib on the upper` 'face of the plate at the thickest portion thereoi, the

In testimony whereof I ailix my signature 30 in presence of two witnesses.
