I TIE-PLATE.

Application filed December 2, 1910. Serial No. 595,218.

Be it known that I, CLIFTON W. SHER- MAN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful rovements in Tie-Plates, of which the Imp folr owing is a specification.

his invention relates to tie plates which are interposed between the undersides of railway rails and the upper sides of ties for the purpose of providing a better support for the rails and reducing the wear on the the tie plate is provided.

v of 2 sheets: Figure 1 1s a top enables the rail to be the rail to creep under ing load on the same.

.bling the tie,

ties.

One of the objects of this invention is to provide a tie plate of this character which secured more firmly to the tie and thereby reduce the tendency of the action of a mov- Another object of this invention is to provide means wh1ch permit of readily assemrail and tie plate and thereby facilitate proper installation of the railway.

My invention has the further object to provide a tie plate which will be reliably interlocked with the tie so as to effectually resist any tendency to move laterally relatively to the rail or to rotate about a vertical axis which otherwise would operate to loosen the rail holding means with which v In the accompanying drawings consisting plan View of a rail, tie and tie plate showing'the manner in which these parts are arranged relatively to each other preparatory to interlocklng the tie platewith the rail and securing the rail and tie plate to the tie. Flg. 2 1s a similar view showing these parts secured together in their relative operative positions. Fig. 3 is a bottom plan view of the tie plate and the adjacent part of the rail.

A re resents a wooden tie and B a rail both of which .are of the usual and well are adapted to receive my improved tie plate.

0 represents the body of the tie plate which is generally of flat form and arranged horizontally between the upper side of the Specification of Letters Patent. v Patented Sept. 24, 1912'. 1

tie and the underside of the base 6 of the e tie plate body ranged opposite one of the fastening hooks.

These spike openings are adapted to receive the shanks of spikes F, F which are driven downwardly into the wooden tie so that the heads thereof engage over the base of the rail andfithereby securely connect the tie, tie

plate and rail.

In assembling the parts the tie late is first placed in an oblique position etween the rail and tieso as to permit of passing the base of the rail downwardly between the bills of the fastening hooks D, D and engaging the undersides of the rail with the top of the tie plate body. The distance between the bills of the hooks is just sufiicient to permit the base of the rail to be passed downwardly between the same, as shown in Fig. 1*. After the rail has been thus deposited upon the tie plate the latter is turned horizontally and about a vertical axis located midway between the fastening hooks so as to carry the bills of the hooks over the adjacent parts of the base of the rail and to engage thebacks or shoulders of the hooks with the opposite edges of the rail base. To permitof thus turning the body of the rail properly the underside of the sameis provided with a downwardly tapering or conical centering spur or pivot 9. After the tie,

rail and tie plate. have been preliminarily assembled preparatory to being fastened to-, as shown in- Fig. 1, the pivot or gether,

spur of the body is driven slightly into the upper surface of the tie by a slight downward blow u on the tie plate and rail,

whereby the tie plate is pivoted on the tie' plate has been thus driven .the tie plate is turned loo upper side of the rail base and the backs of the hooks engage this. base. B tie plate witx with opposite edges of illllSPlVOllilllY connecting the the tie it is possible to turn the tie plate and engage the hooks thereof properly with the base of the rail with facility and without liability of getting these parts out of place relatively to each other and also keeping the tie-iplate on the central cient in supportin. the tie plateand the rail resting thereon. i In addition to thespikes F, the tie plate is fastened to the top of the tie by means of a locking spike F which passes through an opening 6 formed in a lateral enlargement h of the tie plate body which is arranged adjacent to the outer side of the outer'hookD of the tie plate.

In assembling the parts the spike F on the inner side of the rail is first driven home partway leaving the same comparatively loose. The spike F on the opposite or outer side of the rail is then driven fully home into the spike opening a so that its head engages with the adjacent part of the rail base. The relativeconstruction of the rail, spike F and spike opening 6 is such that the outer side of this splke "engages only with the outer side of the spike opening 6 and the inner side of the shank of this spike engages only with the adjacent edge of the rail base, whereby the opposite edge of the rail base is firmly held or pressed against the back 0, the opposing'hook D of the tie plate. The locking spike'F is now driven fully home through the opening e of the tie plate and into the tie so that the head of this spike engages with the top of the, tie plate and only the inner side of its shank engages with the corresponding side of the spike opening whereby the back or shoulder of the adjacent fastening cent edge of the rail base. The driving of the first mentioned spike F is com leted before the driving of the spike F 15 effected so that the head of the spike F bears against the base of the rail opposite to the hook D and the inner side of its shank bears only against the adjacent edge of the rail base and the outer side of its shank bears only against the outer edge of the spike opening -e, whereby this side of the rail baseis held down upon the tie plate, and the back of the hook I) is firmly held against the opposite edge of the rail base. l/Vhile thus driving the several spikes the pivot spur g is forced fully into the tie so that the underside of the tie plate bears fully against the part'otthe tie where the latter is most efiihook D is firmly crowded against the adjatbp of the tie. .The driving of the spikesalso causes the tie plate to turn slightly hori- -7 ontall v on the vertical pivot spur, thereby increasing the grip of the backs or shoulders of the tie plate hooks on the rail base and etl'ectuaiiy resisting the creeping action of the rail.

For the purpose of aiding in resisting lat- 6 eral displacement of the tie plate on the tie in all directions the underside of the body is provided with one or more circular anchoring ribs 2' which are arranged concentrically relative to the pivot spur and arepreferably V-shaped in cross section so that they may be easily driven into the top of the tie. Owing to the ircular form of the ribs 5 the same resist lateral strains in all directions'and thereby reduce to a minimum the possibility of displacing the late later-- ally. The underside of the tie p ate is also provided with a plurality of radialanchoring ribs 3' which preferably connect with the circular ribs, 'as shown. These radial ribs are also driven into the tie and serve principally to resist turning of the tie plate about its vertical axis in a direction'whichtends. to'loosen the engagement of the hooks with the base of the, rail. For the purpose of enabling the radial ribs to offer the greater resistance against movement of the hooks away from the rail base these ribs are made ratchet-shaped -in cross section, in other words the front side is beveled or inclined and the rear sideis straight, abrupt or vertical, as shown inFigs. 5 and 6, which-faces are 50 arranged that the vertical faces receive the thrust which tends. to move the hooks away from the-rail base and thereby most efi'ectually resist this tendency.

It will thus be noted that my improved construction of tie plate not only provides. a substantial bearing for the rail on the tie and reduces the wear on the latter but the same also permits of firmly holding the rail both against lateral displacement when used on curves in the roadway'and also minimizes longitudinal creeping of the rail as the cars run over the same. 1 I i I I claim as my invention: P 1.
