. This invention relates to means for protecting railway ties from the wearing effect of rail anchors and has for one vobject the provision of means for preventing the rail anchor from abrading the face of thetle.

A'further object is the provision of means for receiving the pressure of the rail anchor and preventing the pressure from being transmitted to the rail spikes. Other objects and advantages will appear from the following description. I d

The invention isexemplified in; the com.- bination and "arrangement of parts shown in the accompanying drawings and described in .thefollowing specification, and itis more particularly pointed out; in. the appended claims.-

Inthe drawings I r v Fig. 1- isan elevation of a portion of. a railway rail showing the present invention applied thereto, the railway tie being shown in. section; r

Fig. 2 is a section on 1i1 1e 2 2of Fig. 1; Fig. 3 is a perspective View of the bearing plate shown in Figs. 1 and 2;

F igs, 5, 6, 7, 8, 9. and lOare all perspec- 'tive views "of modified forms of bearing plates. a ,7 i Y The railway tie 11, shown in Figs. 1 and 2 is provided with the usual tie plate 12 which supports the rail 13 and through which the spikes 14: are driven for securing therail to thetie. A rail anchor 15 of any suitable or approved form is clamped to the rail 13 for preventingjlongitudinal vmovementof the rail upon its supporting ties. A bearing plate 16 is interposed'between the anchor 15 and the lateral face of the tie 11 to prevent the rail' anchor; from abrading the face of the tie where it engages, the same.

In the present practice wherearail anchor is permitted to bear against the lateral face of the tie, the relative movement of the railand tie soon wearsaway' the wood fibers so that the anchor either becomes"ineffective or engages the edges of the tieplate. Where the anchor contacts with the tie plate, pressure exerted thereby is transmitted to the tie plate and throughthe tie plate to the spike s. This has a tendency to loosen the spikes so thatthey become ineffective for holding the rail in place. This thrust against the track spikes has the effect of en .is large.

larging the spike holes, thus permittingwater and moisture to enter the untreated ce'nter of the tracktie and acceleratingthe decay of the tie. It'often also causes splitting off the track ties and because of the pulling elfecton the spikes necessitates frequent re-d'riving' of spikesone ofthe causes of so called spike killed ties. I It also has the effect ofkeeping thetie plate loose on the tie which accelerates the mechanical i wear of they tie. Under present practice the rail anchor moving upward anddownw'ard with the wave motion of, the rail under me fic, tends to out and weartheftrack tie; A wide bearing surface on the 'f lateral face of the rail anchor is of little service in overcoming this evil for the reasongthat there is-a' certain amount of. vertical movement of the rail relative to the tie and this vertical movement will wear away the. fiber. of the wood even though the bearingsurface Increasing the bearing surface merely, postpones for a short time the evil day when the anchor will reach the edgeof the tie plate. 1 To provide a flange on theltie plate arranged to extend between the tie and the rail anchor also fails to 'overcomeffthe difliculty for ifthe flange isrigid with the tieplate, the pressure against the'flange will be, transmitted to the spikes because the metal of theftieplate forms. a'more rigid strut for transmitting the forceto the spikes 7 than does the wood against which the flange would rest. Furthermore, any shrinking or wearing ofthe tie between'the plate'and spike would transfer the pressure from the tie to the spike. 1

In the present invention, thefbearing plate 16 is entirely separate both from. the rail anchor and thetie plate. The plate maybe heldin place in a n-umberof different ways the form shown in Figs. 1, 2 and 3 being provided with a laterally extending relatively' thin flange 17 which is driven between the tie plate 12 and the upper face of the tie, as shown in Fig. 1. The fian'ge 17 may be driven in until the plate 16' bears-tightly against thelateral face of thejt-ie. The an-. chor 17 is then placed in position closely against the bearing plate 16 sov that the bear-v ing plate is retained in place and the rail anchor is providedwith a metalb'earing surface which transmits ltspressureto the surface of the tie without interfering With the tie plate or spikes. Any abrasion caused by the movement of the rail will be borne by the surface; of .tlie bearin plate, thus fpro tecting the face of the "tie iroin wear.

In the form of the invention shown in Fig;

4, the laterally projecting flang 18 is made narrow so that it forms a narrow tongue to be inserted between the tie' plate and tie. This permits a larger range-of lateral adjustment transversely ofthe rail than "does the broader flange shown in Fig. 3. In'some forms "of rail anchors, it'is desirable to have e be Pl t e en b y n h a s flangeof the rail in the directionot "the length of the tie; The comparatively na'r-j row tongue 18 of the'f ormshowninFig.4

will permit the" bearing plate to eXten dbeybnd the rail flange at eitherv side ofthe rail; In the form of the inventionshown in igi 5, the bearing plate 16 isfprovidedwith spaced tongues 1 9 "lVith thisfor'm of the invention, the tongues may be driven on op p ses/ides Q a pike at i f he ai pbsi ion ne' he r s" P e at 2s side of the rail flange and providing a firin attachment because of the two tongues ex tending" between the tie 'plateand the tie.
