| 20090090790 | APPARATUS AND METHOD FOR REPAIRING WORN RAIL SHOULDERS - In a railroad system a track is formed of ties positioned at predetermined intervals along the right of way, and supporting a pair of rails. Shoulders are disposed in pairs adjacent to the sides of each rail and are partially imbedded in the ties to limit the lateral movement of the rails and define the track gauge. Between each pair of shoulders there is provided a pad disposed under the respective rail. Insulators are provided between the sides of the pad and a respective shoulder. Over time, friction between the insulators and the shoulders may cause excessive wear. This wear is compensated by one or more shims attached to the shoulders by a strong adhesive. | 04-09-2009 |

The insulator includes a bottom plate having a first side and a second side and a pair of side plates attached to the bottom plate. Each side of the bottom plate defines a notch therein. The side plate includes a longitudinal extending body having an upper surface and a lower surface and defining a recess on the upper surface and a protrusion on the lower surface, wherein the protrusion of each of the side plates is received within the notches of the bottom plate. | 04-30-2009 |
| 20130168460 | System for Fixing a Rail onto a Foundation and Support Plate for Such a System - 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. | 07-04-2013 |
| 20130206854 | System for Fastening a Rail and Method for Renovating a Rail Fastening Point - A system for fastening a rail to a solid foundation, and a method for renovating a rail-fastening point. The system and the method allow a fastening point for a rail to be easily and economically renovated in such a way that a permanently reliable function of the renovated fastening is then ensured again while the worn support section remains. The system for fastening a rail to a solid ground foundation includes: a layer formed by a compensating mass applied to the support section; a base plate resting on the layer and extending over the support section, upon which the rail is supported in the finally installed state; a spring element for exerting a resilient elastic retention force on the rail; and a clamping element that can be anchored in the solid foundation for clamping the spring element. | 08-15-2013 |
| 20130284820 | Combination of a Guiding Plate and a Wedge Element and System for Securing a Rail for a Rail Vehicle to a Substrate - A combination of a guiding plate for laterally supporting a rail and a wedge element for adjusting the position of the rail relative to a counter-bearing, on which the guiding plate is supported. The guiding plate has an end face which is associated with the wedge element and which extends in the longitudinal direction and a lower side associated with a substrate. Between the guiding plate and the wedge element is a positive-locking guide along which the wedge element can be displaced in the longitudinal direction of the end face of the guiding plate. The guide between the wedge element may act as one joining partner and the guiding plate may act as another joining partner wherein, in one of the joining partners, there is formed a slot-like guide orientated along this joining partner and the projection of the other joining partner engages in a positive-locking manner. | 10-31-2013 |
| 20140124588 | RAILWAY RAIL SUPPORT PLATE - This invention relates to a support plate for supporting a railway rail on a rail support member, said support plate comprising a lower surface for directly or indirectly contacting a mounting surface of the rail support member, an upper surface for directly or indirectly supporting the rail, and an intermediate region interposing the upper and lower surfaces, for reducing support plate weight. | 05-08-2014 |
| 20140144999 | RAIL SUPPORT ASSEMBLY WITH IMPROVED SHOULDER - A rail support assembly for mounting and supporting the rail of a railroad system, the assembly including a plate disposed under the rail and including a shoulder hole, a shoulder arranged and constructed to fit in said shoulder hole without rotation with respect to the plate, and a clip having an end received by said shoulder and arranged to bias the rail toward the plate. | 05-29-2014 |
| 20140231534 | END RESTRAINT FOR TURNOUT - An assembly for securing at least one rail to a substrate has a longitudinally extending rail plate extending across and secured underneath the rail and having a pair of opposite ends. Respective end restraints at the ends of the rail plate each have a jaw fixed to the respective end of the rail plate and each formed with a vertically throughgoing passage. A respective rigid anchor hood is fixed to the substrate in each of the passages with an outer surface of the anchor hood spaced inward from an inner surface of the respective passage and forming an annular space therewith. A respective rubber bumper mass fills each of these spaces so that forces transverse to the rail are transmitted through the bumpers to the anchor hoods. | 08-21-2014 |

| 20160017545 | System for Fastening a Rail on a Subsurface - A system for fastening a rail on a subsurface, includes a support plate having a contact surface, and at least one guide plate that is seated on said support plate and has a passage opening for a clamping element, which leads from the free top side thereof to the bottom side thereof. The clamping element is guided through the passage opening and is fixedly connected to the subsurface. A latching connection between the support plate and the guide plate is formed in the region of the passage opening by at least one latch arm. The latch arm engages through said passage opening and has a latch projection which interacts in an interlocking manner with a stop formed on said guide plate. A recess is moulded into the circumferential surface delimiting said passage opening of said guide plate, in which recess the respectively associated latch arm is seated. | 01-21-2016 |

| 20140217192 | ADJUSTER FOR TRACK-MOUNTING ASSEMBLY - A mounting plate fixed to a longitudinally extending rail is secured by a plurality of bolts in a substrate. The mounting plate is formed at each bolt with an array of ridges. An adjuster plate formed with a vertically throughgoing transversely elongated slot through which the respective bolt extends has a lower face formed with an array of downwardly projecting generally complementary to the ridges of the mounting plate and an upper face formed with a central recessed seat defined between two longitudinally extending and parallel edges at a predetermined transverse spacing. A gauge plate formed with two parallel outer edges spaced apart by a distance substantially equal to the transverse spacing of the seat edges and with an eccentric circular hole of a diameter substantially equal to an outer diameter of the shank of the respective bolt that extends vertically through the circular hole fits in the seat. | 08-07-2014 |

| 20160160450 | Base Plate and Rail Fastening Arrangement - 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. | 06-09-2016 |
