Abstract
A railway track in which a rail is supported within a groove of a rail bed. The groove has outwardly sloping shoulders each spaced from the sides of the rail. Continuous clamps extend along each side of the rail. The clamps are secured by spaced apart hold-down assemblies positioned vertically between the clamps and the respective sloping shoulders to secure the track against both vertical and lateral movement. Elastic material pads completely isolate a rail from both the bed and the clamps.
Claims12
A railway track support and fastening arrangement comprising, for each rail, a substantially continuous rail bed for supporting a rail of the track, said rail having a bottom face;
- said bed having a longitudinal groove presenting an upwardly facing support surface and sides presenting lateral shoulders outwardly sloping facing each other and on opposite sides of and spaced from a rail;
- a substantially continuous pad of elastic material within said groove and between said support surface and the bottom face of the rail;
- substantially continuous clamp means on each side of the rail for securing the rail vertically and transversely, each clamp means being within said groove and comprising a plurality of clamp elements in adjacent end to end relation along the length of the rail, a substantially continuous lining pad between each clamp means and the rail;
- said pads and said lining pads comprising means for isolating the rail from the rail bed and from the clamp means, fastener means within said grooves at each side of the track for fastening said clamp means to secure the rail vertically and transversely, said fastener means comprising a plurality of spaced apart hold down elements extending downwardly between said clamp means and a lateral sloping shoulder of the groove, said hold down elements being supported laterally by said sloping shoulder to retain the rail laterally, and means securing said hold down elements to the rail bed.
