mu'rronniirnn TIE-PLATE.

Application filed January 21, 1921. Serial No. 438,952.

To all whom t may concern: y

Be it known that I, FREDERICK A. Pmis- ToN, a citizen of the United States or America, residing at yHighland Park, in the county of Lake and State of Illinois7` have inventedcertain new and useful Improvements in Anticreeper Tie-Plates, of which the 'following is a specification. l v

My invention relates to an anticreeper tie plate.

It is common practice in the construction and maintenance of railways to provide metal4 plates on the ties underneath the rails, particularly when soft wood ties are used, in order to provide a seat 'for therails which plates protect the ties from unnec-` essary wear and serve to prevent turning n movement of the rails about their Alongitudinal axes with the consequent liability to cause train derailments and the cutting of the ties by the rail base flanges. It isv also` 4common practice to provide anticreeping devices to prevent longitudinal creeping oi the rails on the ties. The anticreeping devices are embodied in structures separate and distinct from the ordinary tie plates and add considerable to the cost of track lequipment and maintenance. The primary object of my invention is to provide an improved `combination anticreeper and tie plate which isof simple construction and eiiicient in operation or use.

Some attempts have 'been made to pro vide a device of this general type in whichv a jaw is provided adjacent one end of a tie plate of ordinary-width and a spike open-` ing at the other end, the jaw being arranged j so asl to grip one of the base ianges of the rail when a spike is driven through said opening into the tie. The passing of a train over the track results in the rails being subjected.` to a wave-like motion, the eect of which is to tilt each tie plate upwardly in the direction of movement of the train as the wheels approach the tie, and to tilt the tie plates in the opposite direction as the wheels pass over and beyond-the tie. This rip-anddown tilting .or rocking movement ofthe tie plate causes unnecessary wear on the bottom of the rail base and also causes the edges ot the tie plate to cut into the Jface of the tie considerably bruising and damaging it; This tilting action of the tie,

and in enlarging the spike openings. If a tie plate of ordinary width is anchored to the tie in a manner to obviate saidtltin'g or `rocking movement the disadvantages above noted are to a considerable extent` overcome, but in that ycase the wave-like motion of the rail tends to spring thejaw or' the plate to such `an extent that it no longer securely gripsthe rail base flange. Consequently such a tie `plate is ineffective as an anticreeping device. A more specific object of my inventionis towprovide a tie plate consisting of two relativelyV narrow independent members which are` adapted to be placed side by side on `the tie to provide a seat for the rail, each member adjacentv one end having a gripping jawy formed integrally ytherewith .and adapted to fit over tively, engage the opposite rail base flanges,

each member adjacent the other end having a spike opening which extends partially beneath the railbase so that. when a spike is fdriven therethrough `the member is moved transversely with respect tothe rail y base andthe jaw is forced 'into' eiiective holding engagement with vthe adjacent flange.A l l The invention consistsin the novel and improved constructions, arrangements and.

devicesI Pto be hereinafter described and claimed for carrying out the above stated objects and lsuch other incidental object-s as will appear from the following description of a preferred embodiment of the invention illustrated injthe accompanying drawings, in which- Fig; l is a-plan view of a device embodvingthe principles of my invention,

Fig. 2 is a sectional view taken onk the line' 2 2 of Fig. l showing the approximate position oii' the device relative to the rail basejust prior to. driving a spike through the spike opening provided in the device opposite thejgripping jaw, and y Fig. 3 is a view similar toy Fig. 2 showing the yposition of the `device relative to the rail base after the spike has been driven home.

Like characters of reference designate like parts in the several views.

Referring to the drawings it will be seen `that the combination anticreeper and tie plate shown therein comprises a parof Ilatively narrow members 5, 5 placed side by side a short distance apart on the tie underneath the rail G longitudinally with respect to the tie 7 but transversely with respect to the rail. The ' members 5, 5 are each formed from a plate by rolling,- and provided adjacentone end with an overhanging jaw 8 which is adapted to fit over one of the rail base flanges, The members 5, 5 are arranged so that the respective j awsS, 8 thereof en- `sage the opposite' rail base flanges. rllhe jaws 8, S are each formed or shaped so that the aneularit of the bearino` vsurface 8 thereof, before the member is in operative posi-tion under the rail base, is less than that of' the tcp surface of the rail base flange 'with which it comes into contact when the member is in operative position under1 the rail base, consequently said jaws have to be forced' open or sprung,` slightly upwardly when the members are in operative position under the rail base.

rl-he members 5, 5 are each provided in the end opposite the jaw Szwith a spike opening 9 which is located with respect to the jaw 8 vand the width of the rail base,

secure that end of the plate to the tie. The,

openinnll is located far enough away from the aw so that when the spike 12 is driven home there will be notendency to spring the jaw open and thereby loosen or weaken its hold upon the rail base flange.

A plurality of stiflj'ening ribs 13 of any de-V sired shape are preferably provided o n the bottom side .of the plats to prevent dis-` place. nt of them on the tie.

The shape of t-hejaw 8 and the location of the spike opening 9, with respectto the j awy he width'of the rail, result in the pla e Vb firmly anchored to the rail base the `spike 110 is driven into. the tie. The vspikes-10 and 12 firmly anchorv the ate tothe tie= 'lV ith a combination antieeper and tie plat-e` constructed according to. my invention the rails are held at each tie'against creepage in either direction.. rlhe two tie plates being relatively narrow in width and'independent of each other, are

j not subjected to up-and-down or rocking movements, atleast to. anyappreciabl'e eX` tent, when the rolling stock passes: over the rails. Tl'i'erespective jawsV of* the tie plates are not pried up when the rolling ,ose

stock passes over the'i'ails, as is the case when relatively wide tie plates are used, and they do not, there-tore, loose their grip on the rail base flanges.
