vide a construction including a sub-support beneath the ties and extending longitudinally of the rails and embedded in the foundation or road bed, and coupled to the Vrails through the ties. n

The marked increase inthe weight ofthe struction requires a corresponding increase in the strength and stability-voftheroad bed, including the rails, ties andfthenjsupports therefor, and the improved structure herein disclosed isl designed togeiectually"accomv plish the above resultsand preventany tendency of the rails andties vto settle or work loose under the severe strains to which they are subjected. Y n Y 1 ,n y l lVith the usual' construction of trackage, the constant pounding or hammering of the rolling stock, especially of the very heavy locomotives now used,soon produces anuneven surface over which the vehicles move, and thereby caused to quickly destroy the lroad bed units and materially-iV increase the cost of maintenance.y l In the usually constructed road bedwincluding the single wood tie at spacedinter-v vals, theties are liable to be embedded in' the ballast, especially where soft spots 'oc cur,y and cause 4the rails to settleand the trains thereby to run unevenly ,and materially increasing the severity of the pounding action. Because ofthe lightnessof the usual sizeof tie, the heavy locomotiveand the cars that follow, cause the unevenness of the trackto be accentuated and the locomotive and carsY tosway 'fromside to side, thus ma.- terially increasing the tendency of the rails and ties to be misplaced both vertically and transversely. To prevent the swaying of the rolling stock'due to theuneven track, the

method comprising thisginvention is to pracc i925. s'eriai'nb. 42,539., n

'Ihe improvedftie and its supports herein Idisclosed will` effectually overcome the objectionsfabove noted, andA hold the rails lin position Vand effectually resist any ,tendency to displacementeither laterally or vertically. The improved device is best illustrated in Figure l is-a planview of a section o'f-a Figures 4 and 5 aredetached perspective .A c the vaccompanying drawings, in which:V n Another objectV ofthe inventionis to prorailway track constructed in accordance with views from aboveand from beneath,yoffone of thevimproved tie plates.y

The upper rails are the foneson which the,v

rolling stock moves, while the lowerrails are embedded in a oundationor bedding, pref- .5 erablyof lrock ballast, gravehhard clay, or

By this means the transverse areaof the increasing the lengthof .theties v he widespread secured; bythe staggered arrangement of the doubleseries Vof ties materially increases the ground footing or spread, equal to nearly four times the ordi- 10o:y tie support is materiallyfincreased without los nary arrangement with the single tie, `and Will carry a'material increase of Weight of the rolling stock'without deflection. f

creases the stiffness and stability of the structure and helps to carry the heavy lead of the train without vibration and holds up the top rail and relieves the bearing down load and strainv on the upper vrai-l at any one point, and inaddition holds up and supports the joints and ties of the upper rail, besides.

distributing the weight along the track in a similar manner to a truss carrying a load.A

The joints of the single track .rail as or-r dinarilyconstructed are liable to deflection -u-nder heavy loads, and require constant adjustment. Y I Y The lower rail materially increases the stillness and maintains the track in alignment, and' prevents it from lateral displacenien-t or working out of line, Vas" the lower rail being embedded in the foundation and firmlybolted to the ties and to the upper rail, eflectually prevents any lateral; displacevine-nt or creeping of the rails.

The whole track is firmly' tied together .and its weight materially increased which is essential, and the bearing surface oftheties also materially increased and maintains the bearings lfor the ties uniform andcarrying the load equally as the train passes over.

No single tie or pair of tiesca'n become embedded in the ballast at a' soft spot, nor to give way undery the load. y Y

After the ties and rails are bolted together, the ballast will be'tainped under the ties. and between and under the rails and outside of the same, as illustrated inlfigurev, andthe track levelled up to line.

The lower supporting rails 11 may be old worn out rails, the two sets o'f-ra'i-ls being u-nited by clamp bolts 14 and clamp plates 15, as shown. y

The jo-ints between the upper rails are reinforced by the usual fish or clamp plates lWhat is claimed and desired to be secured by Letters Patent is z Y 1. In railway construction the ties arranged in spaced pairs, the unitsl of each.
