4 'Be' it known'that I, EDWARD: POSON, a

aperture 4 extending therethrough in a 'direction transverse of the'rail f5', fwhichfis designed `to rest upon the-tie plate' between the lugs. 81am?,-

'f In orderuto'hold the railin place,"I pro.V

vide wedges 6` designed to be inserted thronghthe apertures 11 in a direction ltrans.-

verse' of therail. Y Each of the wedges is provided with an inclined surface 7, delsigned to conform to the upper surface of the 'rail lbaseS, and is further provided with a downwardly projecting lug 9 designed to rest upon the main body or base plate of the 1 structure.

For the purpose of holding the wedge in its hom'e position, I use preferably the lockingdevice 10 shown in detail in Fig. 6,

which illustrates the lock in its initial condition.- At its inner end, that is, the .end

designed to lie adjacent the rail, the lock l0 l is provided ,with an upwardly' projecting lug '11, designed to rest against thel inner face of the lug 3, as shown in Fig. 1.. At a distance from the lug 11 equal to the Ithickness' of thelug-B, the lock 10 is provided .withfoutwardly projecting shouldersslQ designed to' rest against the outer surface of the lug.' 3. u

In'assembling the structure the -rail 5 is placed upon the tie plate, as shown in Fig. l# OneI ofthe locks 10 is then placed in position against theupper side of the opening 4 in the vlug 3 with its lug 11 resting against the inner face of the lug3,and its lugs 12 against the outer face ofthe lug 3. Ait this time the outer end 13 ofthe lock in. dotted llines in Fig. 1. The wedge 6 is then inserted. injplace. and driven home, thereby causing a; firm' wedging contact between the' surface 7 of the wedge and the up er surfacev of vthe rail base 8. After the weglgef is .driven home, the outer endl of 'the lu'g L10 is bent downwardly to the posi- .tionlindiated in' full lines 'in Fig. 1, thereby irmly'isecuringfthe wedge inposition and preventing -any possibility of displacement. The shoulders 12 upon the lock 10V serve to hold said lock. against inward movement l when the Wedge 6 is driven to-its home posibending upwardly and inwardly apart-of the base plate of the structure. Y M

In the initial assemblage of the parts, the tie plates are. spiked to each tie at such vdistances apart that when the rails are separated to the utmost limit permitted by the outer lugs 3 upon the two tie plates; the proper rail gage will be secured. Referring to Fig. 1, the letter a indicates the inner side of the rail head, that is, the side toward the center of the track. It will be ob,- served that the outer edge Za of the rail base lies in contact with the outer lug 3. As .above stated, the tie plates are so spaced upon the 'ties that when a new rail is mounted upon the tie plates with its outer edge b in contact with the outer lug, the proper gage will result. As the rail head becomes worn from use, and it becomes necessary to set the rails closer together in order to restore the proper gage, the 'rail is moved in# ward, that is,l to theleft, as illustrated in Fig. 1, and a piece of metal or shim 20 is introduced between the edge b of the rail base and the lug The wedge '6 at the 'left 'is then driven home and locked in place, thereby forcing the rail against the shimand the shim against the right hand lug 3. The wedge 6 Vatthe right is then driven home, thus leaving the rail in its new adjustment. The lugs 3 upon the tie plates are spacedapart suiiiciently to permit the maximum adjustment for wear ordinarily needed. As will be noted upon reference lto Fig. 1, I have -shown a clearance space at c, this space representing. the amount which the distance between the lugs exceeds the width of the base rail. eighth of an inch clearance will permitthe adjustment necessary for taking up wear and restoring the standard gage.

In the assembled structure it will be noted that the rails lie over Vthe apertures formed by bending the lugs upwardly. The downward pressure of the wedges on therail base tends to slightly depress the base of the rail into the aperture formed by displacing the lug, thus effecting a slight depression which has a tendency to prevent the rail from` creeping. V

What I claim is- 1. A device of the class described com- Ordinarily an.

prising'a base plate .v adapted tosupport a rail, upwardly projecting lugs adapted to lie at opposite sides of said rail, a wedgel f adapted to pass through an aperture in one of said lugs and having an inclined-lower surface adapted to engage the rail base, a d

. a lock having shoulders engaging theou er end of said wedge and the inner4 and outer sides of said lug. n

2. A device of the class described comprising a base plate having lugs projecting from the upper side thereof, said base plate being adapted to support a rail; between said lugs, one of said lugs projecting upwardly and inwardly t0 conform to the base of said rail,'and the 'other lug having an aperture extending therethrough trans-y versely of said rail, a wedge adapted to pass through said aperture and engagethe base of lsaidrail, and .a lock having shoulders engaging the outer end'of said wedge and the inner and outer sides of said lug.-

- 3. A tie plate comprising a base formed of rolled metal and adapted to support a rail, integral lugs connected with said base at one edge .and formedv by Severin other edges from said base plate and nding said lugs upwardly on the connected edge, said lugs being perforated and adapted to lie at opposite sides of said rail, 'and tions and having inclined lower `surfaces to engage the rail base.l 1 f 4. A tie plate comprising abase formed of rolled metal and adaptedto support a Jrail, integral lugs connected with said base at one edge and formed by Severin the other edges from said base plate and ending said lugs upwardly on the connected edge, said lugs being perforated and spaced apart a distance greater than the width of the wedges adapted to pass through the perforahaving inclined surfaces to engage the rail base, and a lock engagingthe inner face of said lug and the outer end of said wedge. 6. A .deviceof the class described com# wardly projecting lugs adapted to lie-at opposite sides of a rail, wedges adapted :to pass through apertures in said lugs and having inclined surfaces to engage the rail 1 base, and 'a lock .engaging the inner .face

of said lug and bent down over the outer endn of said wedge. l

7. In a device ofthe class described,a tie plate comprising a base formed of rolled 12o prising a base. plate to support a rail, upi rated, and wedges passing through the perforatons in said lugs and engaging the base Vof said rail In testimony whereof, I have subscribed my name. t l
