franca Application. med `February "Fhis'iin'vention relatesto tracky liners.

".Oneobject of the invention `is to provide a track Vcarrying lever `adapted .for insert-ion under ,ther rail and movable transversely thei-eoffor shifting the tracklfor ,aligning purposes.

A further :object of the `invention is to effectythe movement of saidvlever throu h the medium'ot a rock arm so' as to `limit t e raising ofthe levcrfWhen` aligning the track to prevent undue lifting ofthe ties from the roadbed tof prevent ballast entering beneath the ties for disturbing the foundation therefor.

\ A furtherobject ofthe invention is toprovidemeans having a ratchet action'to allow for a step by step" application of power for shift-ing the raiIsand ties and retaining the track in its shifted' positio'nsbetweeneach applicationof power. f

A further object of the invention is to obtain this ratchet action:` through Ithe 'medium of an inclined rack on which the levera e applying barhas a stepbyl step action in t e ehittingof the'track Af still furtherwobjectl of the'invention is to havethe' track carrying *lever connected with the2 leverage-applying bar closely adjacent the fulcruni of the latterA1 so as vto increase the leverage applied by the'bar in aligning the track. i *The invention consists further in the `mattersihereinatter described and claimed.

ribs

2, 2 extendialong thevsides of the platel and, as sho-Wn in Fig. 4,have inclined inner sides tohoIdandJpaCk the roadbed between them andthus build up a foundation to resist the downward pressure onE theplate. The ribs 3. 3 extend pcrosswise of theplate 1 and serve to prevent endwise shifting of the base plate in the `useot' thedevice." These ribs, as shown in Figs. 1 and `2,.' are substantially V-shaped y solas tofwedge into the roadbed.

The lowerend of theiarm 7-pivots or rocks on: an axis member 9 extending between and supported by the webs 6, y6,-as Shown. Said lever Lthas a cross-web 10 in itsichannel at i, its outer `end to provide la continuous bearing tori the `roller 5 inl the endwise movement otthelever4.` i

i Tov the rearof the arm 7 is an` actuating lever llpreferably made in socket form to receive an actuating bar12, such as a standa-rddtrackbar. yThe i lever 11 is connected with theffaxis member 8 by a pair of links 13,\\13,` and the forward or fulcrum end of Asaid Vlever .11 actsuonan upwardly inclined rack' means 14' for imparting a step by u step *artionffork lifting andishiftlng a track lrail 1 The forward end of the actuating lever is bifurcated, as shown, so as to have a pair of end portions for engaging the pair of racks 16 and also to receive the pair of links 13, the latter having pivotal connection with the lever 11 by a transverse pin 18.

Pawls

19, 19 are carried by the axis member 8 to co-operate with the steps 17 in the actuation of the device. These pawls are connected together by a transverse web 20 so that they operate in unison.

In use, the device is inserted under the rail 15 until the lever 4'contacts with the adjacent edge of the base flange of the rall, as shown in Fig. 1. If the space between the base flange of the rail and the roadbed is at the minimum, say three inches, the lever 4 is in a position substantially horizontal and with the pawls 19 free of the steps 17 and resting against the vbase plate 1 at the lower ends of the racks 16, as shown in Fig. 1. This will enable the liner to be inserted under the rail so as to bring the adjacent edge of the rail preferably midway between the axis of the roller 5 and the axis member 8. At this time the forward or fulcrum end of the actuating lever 11 is in position to engage the lowermost of the steps 17.

On raising of the bar 12, the lever 11 fulcrums on the lowermost steps 17 and rocks the arm 7 forward to raise the rear of the lever 4 and thereby lift the rail 15 and its attached ties to break contact of the latter with the roadbed to lessen the resistance to the shiftingl of the rail and its ties in the aligning of the track. The pawls 19 ratchet up the first.l steps 17 and hold the lever 4 in yits raised position to retain the rail 15 and itsties'raised. With the pawls 19 retaining the load, the lever 11 is free so that its outer end may be lowered to raise its fulcrum end to engage the next set of steps 17,

Athe links 13 gravitating inward to automatically swing the fulcrum end of said lever into said steps. This allows for another application of power or leverage to the lever 4 to advance it farther forward and carry the rail 15 and its attached ties therewith.

each successive power operation of said lev-y er 11, thereby allowing a single workman to exertconsiderably more leverage or power on the track to shift the same than with track lining devices as^ heretofore made. By holding the track from receding between each power operation of the lever 11, the track is Vretained in its various intermediate shifted positions, thus making the device more effective. Moreover, the track does not spring back to jar and loosen the dirt or ballast of the roadbed to enter beneath the slightly raised ties todisturb the foundation therefor.

As the advance of the lever 4 increases, the lifting of the lever decreases as the arm 7 approaches a vertical position. This is another important feature of the invention because the ties are not lifted high enough to permit ballast to enter between them and the roadbed to disturb the foundation for the track. In the initial application of power to the device when the lever 11 engages the lowermost steps 17. the base plate 1 is forced into the ground so as to obtain a proper seat until sufficient resist-ance vis obtained to lift or support the rail and attached ties in the advanceof the lever 4. Consequently.` by having the track engage the lever 4 in the midway position heretofore mentioned, the amount of lifting given the track is necessarily limited, due to the loss caused by base plate 1 being pressed into the ground. and therefore undue lifting of the track to build up ballast beneath the ties is avoided. The trackis therefore shifted substantially horizontally in the advance of the lever 4 so that no op ortunity is offered for building up of bal ast beneath the ties. i

It will be noted that the forward or fulcrmn end of the lever 11 on engaging the steps 17 exerts a downward pressure on the base plate 1 .on one side of the rail in the upward movement of` the lever, while the weight. of the rail on the lever 4 is exerted downward on the plate 1 on the opposite side of the rail through the roller 5, thereby practically equally distributing the load on the base plate. The pawls 19 engaging the racks 16 adjacent the fulcrumend of the lever 11, also effect an equal distribution of load whensaid lever is free.

The axis member 9 has a fixed position on the base plate 1 and does not change inthe actuation of the device.4 The roller or bearing 5 is also in a fixed position on the base plate and vdoes not change`l as the lever 4 advances or recedes over the same. This pro# vides a fixed distance between the bearing 5 and axis member 9 so that the distance between tlie outer end of the lever 4 and the axis member 9varies in the rocking of the arm 7. As the arm 7 rocks or swings forward, that is, toward the" rail 15, the latter carried by the lever 4, and as the rail approaches closer to the fulcrum 5 of said lever the axis member 9 so that thelever 11 cannot move the arm 7 beyond asubstantiall up-Y ri ht or vertical position, as shown in `ig. 2 T is prevents the lever 4 fromcarrying the rail beyondthe bearing 5 to overbalancev the device and canse the leverageA exerted through the same to beeorneinefl'ective.

With a device of the general size. show-n in the drawings, a single workman `inayexert a leverage as follows. The distance between` ly opposite so as to effect [proper shifting `to place.

theraxismember 18 and the fulcru'm endLof the lever 1'1 is approximately 1% inches'. A standard .trackY bar, such as 12, is about 66 inches long, and with three inches'between the pointed end of this bar and the fulcrum end `of the lever makes an overall length y.of 69`inehes. This providesa leverage exerted through the lever 11 and bar"12 (the latter being an extension of the former) of 46 to 1. When the lever 4"engages the rail 15midway between the roller 5 and axis member 9,A as heretofore stated, the lever" 4 has aratio of 2 to 1`so` as `to donble the ef-` fective leverage 'of the lever 11. Thisfinitial ratio of lever 4 increases yto 2% tolas the rail approaches" the fulcrum 5, thusrcoin`- pounding the leverage exerted by the device in the shifting of the rail'.- In this present device the maximum shiftoftherail'is approximately "five inches; In' ractice, two of the devices willvbe employe 'at the same time, oneV foreach rail, andl arranged directof the track. .y y

` In the firstapplication of power,a lar e portion of the leverage exerted through the levers 4 and 11 is generally employed to lift the dead load of the-rail and` its attached ties. `As Athe rail approaches closer` tothe fulcrum 5 in the `movement of the lever 4, this dead load is transferred closer'to the fulcruni to lighten the load on the lever 11 sol as to increase the` power effect `of the latter for shifting' the track.` j

A loop handle 21 is provided' at the pawls 19 so that the latter may beV manuallyraised up theracks 16 to adjust the lever`4 upward under therail for contact therewith to ac.A commodate for varying distances between the road bed and the rail. This handle may be made integralwith f the pawls and vin` cludes the cross-Web 20: f

Thishandle also allows the device as a whole to be lifted and becarried from place

atthe upper `ends of the racks 16to facilitate insertin'glthedevice under a rail and pulling stepped drown the rack 16 on'the lowering tl1e`lever`4 from contact-with the rail; `To accomplish this, the fulcrumend of the lever 11 is firstengaged with the steps 17 on which the pawls restfand then by raising upward yon' the `lever the load -is transferred from 4the pawlsto the lever 11, whereupon thepawls may be `stepped `down to the next steps 17 belowhby swinging them out by the handle 21. To ste the lever '11 down the racks 17, ak grip han le 23 is rovided at the outer end l andle being grasped to swingthe `fulcrum end of said lever outward from" the steps. n i n i y i.

' To use the device as a jackfor lifting the railV vertically and not *shifting the same laterally, an attachment is provided for the f1ee`end of the lever 4. `This attachment isin the fo'rrnof` a block `24 having anin-` clinedunder surface 25 to ride on theroller 5, asshown in F ig. 6." The block has a` projection 26 on its top to enter an openling y27 at the forward end of the lever 4.

This opening is provided by the web 10,113 shown.

lgThe roller` 5 is grooved, as shown in Figs.

7 and `8,`soasto provide a guide for the block to" hold it from lateral displacement. The block when engaged with the lever 4 disposes thesame substantially horizontal and main-` tains the lever in substantial "parallelism withv the base plate las the arm 7 is rocked to ,raisel `or lower the member 4 for jackin purposes. LThe pawls 19 act as before an hold the member 4 in its elevated positions.

. Theracks 16may `be providedwith u l,

right guide ilanges`28l along theirouters'i e edges, as shown, to prevent the pawls shift- Thefront of the plate 1 is notched, as `at 29to'freceivethe forward or free end of the lever 4 when shifting a rail, as shown in Fig. 2.k The web 10 may be setup into the lever 4 so that the side flanges of the bar embrace Ythe roller 5""as shown in"Fig. 8,to guide the bar. As shown in Figs.. 2 and 6, the

roller 5 and the lower end of `the arm 7` work inadepressions or recesses l, lb in the base 1, so `as to reduce the overall height ofthe device especially when collapsed, `as shown in Fig. 2, to be insertedunder a rail. The details of structure shown Vand i described may be variously changed and modied without departing fromlhe spirit and scope of the invention. y r
