  • Patent number: 9758933
    Abstract: A base plate includes a lateral support section and a lateral contact surface which delimits a supporting area formed on a top side of the base plate for a foot of a rail. A through-hole leading from the top side to the underside of the support section is formed into an edge area of the support section abutting the lateral contact surface. The through-hole has a basic shape which is angular in cross-section. The surface of the edge area meets with the contact surface in an upper marginal edge. A lateral surface of the through-hole assigned to the contact surface at least over a partial area of its height changes into an inclined surface which rises in the direction of the upper marginal edge of the contact surface and ends at the surface of the edge area.

    Abstract: A system for fixing a rail onto a foundation and a support plate intended for such a system. The system comprises a guide plate, a spring element which can be clamped against the foundation by means of a clamping element, sits on the guide plate and in the final mounted system with its free spring arm exerts a retaining force on a rail foot of the rail, and a support plate which is arranged to compensate for height differences between the guide plate and the foundation concerned. The system proposes dividing the support into two parts along a joint line which runs, starting from the one long side of the support plate aligned transverse to the rail to be fixed, at a distance from the one short side to the passage opening and from there intersecting the passage opening in the direction of the short side of the support plate.

  • Publication number: 20020011526
    Abstract: A steel tie (20) for incorporation in a rail track has a horizontal rectangular plate (21) for connection transversely of the rail (22) to restrain vertical rail movement and has downwardly inclining margins (21a and 21b) to retain ballast. A web member (23) extends vertically on the underside of the plate member (21). Rail fastening devices consist of a pair of opposing longitudinally extending shoulders (51, 52) adapted to accommodate the rail flange (48) between then. Each shoulder (51, 52) has a downwardly facing abutment surface (77), and a resilient rail clip (53, 153) has an intermediate portion (84, 184) that bears upwardly on the abutment surface (77), an end portion (86, 186) that extends inwardly from the abutment surface (77) and bears resiliently on the upper side of the flange (48) for restraining the rail (22) against vertical movement.

  • Patent number: 6305613
    Abstract: A rail tie plate suitable for attachment to a wood tie has a pair of upstanding abutment members to accommodate a rail flange, each having an upwardly facing lower ramp surface inclining from a laterally outer side of the abutment member upwardly inwardly to a laterally inner side to facilitate insertion of a rail clip. The tie plate tapers in thickness and has an upper side canted with respect to the lower side. The lower side is provided with wedge shaped projections that tapers laterally in the same direction as the plate and have an end face making an angle no greater than 90° with respect to the lower side.

  • Patent number: 5823426
    Abstract: A rail fastening plate used to secure a railway rail to a sleeper or other rail foundation uses a spring clip. The plate includes a base section adapted to be secured to a rail foundation by securing bolts passing through each of a plurality of apertures in the base section. A pair of spaced raised ribs upstanding from an upper surface of the base section, the ribs being spaced apart so as to receive a railway rail therebetween. Channels cut across the ribs are shaped to include narrowed outer sections and a wider central section. The narrowed sections act as a gate through which the clip must pass and which serves to retain the clip in position.

  • Patent number: 5449116
    Abstract: A tie plate with posts is designed for easy insertion of the foot of the rail cooperates with pins through the posts to rigidly affix the rail to the tie plate and to railroad ties or roadbed. The posts may be made of flexible material in which case the rails are snapped into the tie plate. Alternatively the posts may be fabricated from hard plastics, ceramics, or metals, in which case the rails slide into the tie plates. The posts restrain the rail from lifting out of the tie plate or shifting laterally in the tie plate. Pins with fluted, or otherwise textured, surfaces are driven through guiding holes in the posts of the tie plate past the edge of the foot of the rail. The fluted edges of the pin serve to grip the rail. The pins are made of rigid or hard materials so that the pin will provide rigidity to the posts and also slightly deform the edge of the foot of the rail and thereby grip or engage the foot.

  • Patent number: 5288016
    Abstract: A rail-tie fastening assembly for connecting a rail to a tie including a rail seat assembly and a rail anchor. The rail seat assembly is connectable to the tie and the rail seat assembly includes a seat hook assembly which extends over a portion of the rail flange. A portion of the rail seat assembly is formed on a first radius to provide a rail seat curved bearing surface. The rail anchor has an anchor hook assembly which extends over a portion of the rail flange. The rail anchor has a portion formed on a second radius to provide a rail anchor curved bearing surface. In the assembled position of the rail seat assembly and the rail anchor, the rail seat curved bearing surface engages the rail anchor curved bearing surface to form a rocking bearing seat.

  • Patent number: 4921168
    Abstract: A support plate, particularly a ribbed plate for fastening rails of railroad tracks and track switches on wooden sleepers. The support plate is connected in the vicinity of its ends, in each instance, with the wooden sleeper by means of screws or the like which engage in the through-holes, whereas the rail flange is supported in each instance in the area of the plate between the fastening points on the sleeper side. On the underside of the plate, shoulders are provided or constructed only in the area of the through-holes for the fastening screws, which shoulders project out of the plane of the plate and have a thickness of approximately 1 mm to 2 mm. As a result of the cooperation between the shoulders and the fastening screws, the support plate has a convex curvature, so that its underside comes in supporting contact with the upper surface of the wooden sleeper.
