CURVE RAIL PLATE.

' l ppicaticn led May 7,

To all 1/fiom i may cof/warn Be it known thatl l. ll'lnrxrnn H. KIRK- nrunn, a 'citizen' ofthe United States, residing at Palo Alto, in the county ot' Santa Clare and State California, have invented certain new and useful Improvements in Curve- Rail Plates, oi' which the following is a. specification.

vMy inyention'relates, in general. to laste'ning Ineens by which railway-rails nre secured to cross-ties,'and, in particular. it-relates to and consists in a novel assemblage 0r combination of the several members of a fastening comprising as one oi seil` menibers :i supplementary plate, which from its especial use on curves properly be termed s. curve rail-plate, though it is to be understood that it may also he used at other points as for example on tangent tracks, or Wherever conditions may develop e necessity for its presence. y

One object of my invention is to prevent the Widening of. the track-guage., a tendency to which is especially noticeable on curves due to the outward pressure'on the rail.

Another object is to lessen 'the tendency to injury to the fibres of the ties next to the spike holes, by e more even distribution to the tie or the rail-pressure.

Another object is to protectfthe tie from occasional flange cutting due to dernilment.

Another object is to check any tendency of the standard tie-plate to work outwardly under trellis and thus widen the @auge oi track.

' Another object is to relieve 'the excessive pressure on the spikes and thus tie from mechanical wear.

In the accompanyingdrawings, to which reference is hereby made, .illustrate and she/il now fully describe my invention, itl being understood that changes in forni and detail may be made Without 'departing from the spirit of the invention-nsk deiined in the claims hereunto appended.

ln the drawings, Fig. l is e in section of a railway rail fastening embodying my invention, the curve rail-plate being in its simplest form..

Fig. 2 is a plan of the same.

Fie. 3 is e side elevation.. the rail being in cross section, ofl a fastening' embodying my invent-ion, the curve rail-plate being in its morefdeveloped form.

Fig. e'. is a plan of the same.

Fig. is e plan of the metal blank from` protect. the

passing throug l -a supplementary plate underlying the tie view partly/ 192:1.. serial no. 711,823.

which the developed curve rail-plete Figs. 3 and 4 is mede. y.

l is a railway-rail; 2 isa cross-tie; Sistlife ordinary or standerd'tieplate; and l `the spikes, the heads of which engage the foot.

flanges orbese of the rail and the (bodies of which pass down through the tie-plete and penetrate the tie. l I

is s supplementary'plate placed between the tie and the 'tie-plate. ln its simplest forno, as shown in Figs. l and 2, this plate 5 is n flatsteel pla-te. The rail-engaging spikes s which pass through the tie plate 8, also vpass through this plate 5 and said plate is additionally secured to the tie bynieans independent of said rail-engaging spikes, as for example, by screw spikes, orby the leg screws 6 as here shown. ln its .more developed form, When-greater security is'degsirecL- the supplementary plate 5 sss'nnies ...f

Widening rearwardly, fit over the sides of the tie., and are fastened thereto by e through bolt 7. This developed curve plate 5 is also further fastened by means independent of therail enga-ging spikes as .for example by the spike 8.

I' claim:

1. ln e railway-rail fastening, in combination ,with a rail, e tie, a tie-plete vunderlying the rail, and spikes engaging the rail and the tie-plete into the tie,

plate and resting ont-he' tie, the rail engeging spikes passing through said supplementary plate; and means for securin said supplementary plate to the tie indepen ently cf the rail-engaging spikes.

2. In e. railway-rail fastening, in combination with e rail, a. time tie-plate underlying the rail, and spikes engaging the rail and' Y passing through the tie-plete into the tie, a supplementeryA pl te underlyhigthe tieplate and resting on the tie, the rail engaglng spikes passing through seid supplementary plate and said supplementery plete having a step et its outer end zig-einst which the outer edge of the tie-plete shuts; and ineens for securing said supplementni'yplne to the tie independently of the reihengeging spikes.

3. n a, rsilWey-rail fastening, in combination with e mil, e tie, a tie-plaie underlying the rail, and spikes engaging the rail und passing through the tie-plete into the tie,4

a supplementary plate underlying the tieplete and resting on the tie, the ruil engaging spikes passing through said supplementary plate and seid supplementary plete having side members engaging the sides of the tie; and ineens for securing said supplementary plate to the tie independently of the rail engaging spikes.

4. In. e reilwnyreil fastening, in Combination with n rail, a tie, n tieplete underlying the rail, and spikes engaging the mil and passing through the tie-pluie inte the tie, a, supplementeiy plete underlying the tie plaie and resting en'the tie, Jche rail engaging spikes passing through said supplementaiy plate end seid supplementary plate having side members engaging the sides ei" the tie; a belt passing through seid side members and tie; and othei` fastening ineens, independent of the rail-engaging spikes, for securing said plate to the tie.

5. In e railway-rail fastening, in combinamemes tien with e rail, a sie, a tie-plete underlying che mil, and spikes engaging the rail end passing through the tie-plate into the `tie, n,

supplementary plete underlying the tie-l plate and resting on the tie, the rail engegN ing spikes passing through said supple# nientury plete and said supplementary plete having a stop et its outei' end engaging'the ouieil edge of the tie-plate, and having else side members engaging the sides of the tie; und means foi' securing seid supplementary plate to the tie independently of the mii-engaging spikes. i

6. In n, railway-ruil fastening, in combine,` tion with a, mil, a tie, a tie-platfe underlying the mil, end spikes engaging' the mil and passing thmugh the tie-plate info the tie, s supplementary plate underlying the tie plate und resting on the tie, the rail engaging spikes passing throughA seid supplementary plate and seid suppleinentniy plaie having :i step at iis @nier end engaging the outer edge of he tie-plate, and having else side members enga-ging the. sides ef iihe tie: a holt passing through seid side ineinbers and. tie; und other festening nies-ns, independent of the rml-ei'igeging spikes, for securing said plate te the tie.

In testimony whereof I have signed'niy name to this specification.
