My invention relates-toa. railway track liner.

An important object or" the invention is to provide a track liner which will haveY a maximum holding action with the ballast,.to prevent slippage of the liner during the operation.

A further object of the invention is to provide a tract: liner having a movableanchoring element or blade carried by the.v rail shifting bar or lever, which blade Will properly coact with the ballast without previously forming a" recess in the ballast to receive the blade.

A further object of the invention is to provide a trackA liner of the above mentioned character having a base of relatively. large area which comer -ses the ballast beneath the base, due to the Weight of the tract; carredby the. base, and.. a ballast engaging anchoring element or; blade which is movable into; the, ballast andcompresses or crowds the ballast horizontally toward the compressed portion of the ballast beneath the base, thus effectively holding the liner against creeping in a direction opposite tothatin which tract; is to be shifted.

A further object of the invention is toprovide liner oi the above mentioned character which.

is a sell contained unit and .is adapted for use with various types ot jacks.

Other objects and advantagesof ythe.invention will be apparent during-the. course of the following description.

in the drawingsv wherein for the purpose of il lustration is v:shown a preferred embcdimentV of my invention a track `liner is shown comprising a relatively large flatvbase lll'. This base may be about eight inches wide and thirteen inches long, although these dimensions may be varied, as found advantageous. The base. is continuous or imperforate to provide the maximum engagement with thev ballast whereby the .base will compress "the layer of vbellnet*beneath.' itl bsrvirtue oiathe y2 fact` that. thebase carriesfgthef, load of the track, whichis veryheavy. At its vouter endy this base. lll carries. an upwardly; projecting flange or stop l l Near its inner end: the base vlill-'.has; apair ol'verticalrapertured' knuckles. t2, formed integral therewith.

Arranged `above the4 base IB.; Ais a vertically swinging lever or bar'v |131, nrfnzided between its endand nearits longitudinal center with a pending apertured knuckle. 141,; integral therewith, and pivotally connectedwitlr the knuckles l2 a pin l5. Formed' integralfwith the lever or bar i3 and' arranged above. itis. a Web lprojecting laterally beyond thelever I3, to, engage. with the 'base of. the rail, iorpforming a contact having a suitablearca..

Arranged atthe .innerend or4 the lever or bar it is a, ballast. engaging: anchoring elementvor blade ll, having-alarga. area. This blade may be eight inches-long and six..incheswide, although these dimensions may vary. Thisblade is, preferably imperforate so that. its relatively' large.` surface is continuous. The blade has. alower sharp beveled edge I8; with its lower point'disposed outwardly with respect to the track or next to the inner end of the base ld. The blade4v |11 is preferably formed integral with the levery or-bar i3v which is positioned at theY longitudinal-center of the blade El and near its-upperend. The blade-` -Il is arranged at an inclined anglewith respect to the lever-or bar I3, such as an agle-oi`25 from the perpendicu lar with respect to. the-leverwg although this angle may be somewhat varied, The blade Il iS vertically' inclined whenrthe lever I3 is in the horizontal rmsitiony and-this bladev extends from the base lil toward the loweredgev or the blade ll. The. lever orbar 13.115 provided. at. its outer end with. a lack. engaging. yokeor. socket i9.. arranged beneath it., andprefrably formedintesral there.- Wi h.

The liner is adapted ior use in connection with a lifting jack 20. ot any Wellimown or preferred type. This lifting jack may heofthe ordinary track type, including a vertioaihousn's 2l vhaving a. base or foot, 22.,whioh isplacednponthe base It and also. engagestheangeor stop il.' This jack includes. a vertically movable. toe- 23, which is raised and lowered bythe usual manually operated means. This toe engagesl within the yoke. I9', Y f

Theoperation of the liner is as.- follows:

When itis-desired to shifter line the track to the right, Fleizresz and 3, the liner would be arranged beneathftheeleft grail; 'lt-fand between -a pair of cross-ties. It is usually necessary to remove some of the ballast so that the implement may be inserted beneath the rail. The lever or bar I3 is in the approximate horizontal position, when starting the operation, and the anchoring blade ll is vertically inclined, and extends to the right toward its lower sharp edge I8 or from the base til. The jack 20 is applied to the base IE and the toe 23 is moved into the yoke or socket is. lThe liner is adjusted longitudinally so that the outer edge 124 of the rail base 25 is near the longitudinal center of the short arm of the lever, which short arm extends from the pivot l to the yoke i9. When the jack is operated to raise the toe 23, the lever or bar I3 is swung vertically upon its pivot, the short arm of this lever rising and moving to the right, Figure 3. As the short arm rises, the weight of the track is transmitted to the base l0, which causes the base to press down upon the ballast beneath it and form a iayer of highly compressed ballast, the aggregates of which are not free to slip. While this downward pressure of the base l 0 upon this ballast layer is occurring, the anchoring blade l'l is swinging downwardly and also moving horizontally outwardly with respect to the track or toward the base l 0. Since the lower edge of the blade il is sharp, it will readily dig into the ballast and will not overcome the downward pressure upon the base I0, and will not materia-lly reduce the compression of the ballast beneath this base IIJ. The blade Il' crowds or moves the ballast between it and the base IQ toward the base I and this ballast is pressed against the compressed layer ballast beneath the base lil. Hence the blade l1 acts against the ballast which it engages and since this ballast acts against the ballast compressed beneath the base il), the blade l1 eiectively holds the base E@ against creeping to the left, or in a direction from the track, which is a tendency caused by the pressure in that direction from the track. As the lever or bar I3 rises, the base 25 of the rail has its edge contacting with the web i6 at the point 2li, and the web does not slide down the inclined lever I3 as it might be expected, but the base 25 and the entire adjacent section of the track is positively `shifted to the right a slight distance, to line the track. The rail and crosstie are slightly lifted, but the lifting is incidental and is slight as it is not desired that the ballast should get beneath the cross-ties and disrupt the level surface of the track. Since the blade I1 is inclined, at the starting operation, its horizontal moving or crowding of the ballast starts immedtravel by the time the blade I'l is moved downf wardly to the vertical position or slightly past such vertical position. It is thus seen that when the lever i3 is inclined and is exerting the lateral pressure upon the base 25 of the rail to shift the track laterally to theA right, the blade ll' will then be in the lowermost position and forced into the ballast, and pressing the ballast horizontally against the compressed ballast, beneath the base lli, whereby the base It cannot creep to the left.

lt is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be referred to Without 4 departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention., what I claim is:
