Abstract: The invention relates to a rail fastening on a tie having fastening screws and loop-shaped tension clamps in which the track width can be adjusted horizontally in a stepless manner using wedge elements, the rail being arranged on a ribbed plate, the ribs of which run at an angle to the rail and a wedge that can be moved in the longitudinal direction of the rail being arranged between rail foot and the ribs. The wedge is preferably guided on the support. This makes possible effective horizontal lateral displacement of the rail or modification of the track with the use of simple and inexpensive plastic parts.

Abstract: A rail-to-wood sleeper fastening mechanism in railroads, consisted of a clamp having an upper and middle branch fixed to the lower face of a sleeper, and with a pair of lateral and hinged branches, constituting the clamp, going through the sleeper via chimneys, and presenting upper and bent ends, sliding on the upper face of a foot of a rail, when respective wedges are inserted into said chimneys, that can be optionally configured by establishing a hinged union which is removable between the side branches of the clamp and its lower and middle branch, so that said side branches are easily installed and removed.

Abstract: A rail anchorage has a housing in which is received resilient material for bearing on the flange of a rail that the anchorage is to secure. The housing is formed to exert a wedging action on the resilient material when the material bears on the flange, and preferably also when the material is otherwise unloaded. In use the wedging action increases as the force placed on the resilient member increases.

Abstract: An adjustable rail brace assembly for buttressing the head of a rail includes a rail brace having surfaces for engaging the head and the base of the rail and a vertically extending wedging face, a cover plate for retaining the brace having a vertical wedging face which compliments the brace wedging face, and an interlock for interlocking the brace wedging face and the cover plate wedging face such that the brace and the cover plate can move relative to each other in a vertical plane, but are restrained from moving relative to each other in a horizontal plane, and an elastic fastener for engaging the cover plate to prevent vertical movement of the cover plate.

Abstract: A resilient rail fastener having a clip having a lower leg with a toe at one end and a heel at the other, an upstanding back portion between the heel and an upper leg, and a rectangular locating aperture in at least one of its legs which engages over a rectangular retaining block. The retaining block has pressure imparting means projecting from each side and bearing downwardly on the upper leg of the clip and thereby applies a downward pressure at each end of the lower leg. One end of the lower leg bears downwardly on the rail support and the other end on the rail to impart a toe pressure. The reduced cross-sectional area of the clip where it passes over the retaining block causes high stresses in the legs of the clip as well as at the locality of the clip heel, and the upstanding back portion has less stress than a hairpin clip, and this results in a lower spring rate for the toe clip so that toe pressure is retained upon rail settlement, and stress corrosion is reduced.
