  • Patent number: 9702091
    Abstract: A tie plate is formed with a profile defining two parallel protrusions with bores for receiving the respective ends of two clips. The two clips engage the flange of a rail to secure the rail to the plate, and therefore, to tie disposed below the plate. Since the protrusions are made integrally with the the plate, the resulting tie plate is able to support the rail securely even in the presence of large forces and/or twisting moments on the rail resulting from a train passing over the plate.

  • Patent number: 9139959
    Abstract: A system includes a guide plate, a fastening member and a resilient member, for fastening a rail on a solid base. The guide plate serves as a guide for the rail in the horizontal direction and as a stop for movements of the rail in the vertical direction. The guide plate has a contacting surface against which the longitudinal side of the foot of the rail rests. The resilient member which rests on the guide plate exerts substantially no hold-down force on the rail and merely supports the guide plate elastically against the clamping member. The resilient member is of a W-shaped or S-shaped configuration and, in the fitted state, a portion thereof projects sufficiently far over the foot of the rail for it to be retained resiliently by the resilient member if it is moved upwards in the vertical direction.

  • Patent number: 8181887
    Abstract: A device for positional securing and guiding of rails for railway tracks for trains, in particular high-speed trains, includes guide plates. In general, rails are laid directly or indirectly by intermediate assembly of intermediate plates to fixed concrete track beds and guide plates, against which the rail base and possibly intermediate plates lie laterally. Guide plates are embedded on or in the concrete track beds, wherein the guide plates are fabricated of high-strength, form-stable material, preferably reinforced plastic, such as for example glass-fiber reinforced plastic, in particular polyamide. The device according to the invention allows to create guide plates which are overall more wear resistant. Wear resistance is achieved in that the guide plate within the surface area, on which the rail base rests, has an insert or areas provided with inserts, the insert being fabricated of slippable, low-abrasion or friction-resistant, low-wear or wear-resistant and flexibly resilient material.

    Abstract: The invention relates to a guide plate for laterally guiding a rail S for rail vehicles to be fastened to a base 2 by means of a spring element 13 having a front face, against which the rail S is supported in the mounting position, and having an insulator element 19 which can be placed onto the foot F of the rail to be fastened, via which insulator element 19 the spring element 13 in the mounting position acts on the foot F of the rail S. The invention also relates to a system for fastening a rail, which comprises such a guide plate 3. In order to simplify mounting and to ensure reliable, correct positioning of the insulator element even under unfavourable mounting conditions, the invention makes provision for the insulator element 19 to be mounted on the guide plate 3 so that it can pivot.

  • Patent number: 7954727
    Abstract: A shoulder for use in retaining a railway rail fastening clip, comprising two interconnected spaced-apart walls, between which a portion of the clip to be retained is held when the shoulder is in use, and clip-engaging means, supported by the walls, for engaging a portion of the clip to be retained, does not have any feature or surface which engages the surface of that clip portion which faces downwardly when the clip is in use. Alternatively, or in addition, none of the contact regions, at which the device engages the rail clip, can be seen when the anchoring device is viewed from above when in its operative orientation and all of the contact regions can be seen when the anchoring device is viewed from below when in the operative orientation. Alternatively, or in addition, all the contact regions lie substantially at the same horizontal distance from the edge of the rail foot when measured perpendicularly to the axis of the rail and in the plane of the rail foot.

    Abstract: The invention relates to a system for securing a rail, including a guide plate for providing lateral support for the rail to be secured, a spring element supported on the guide plate and having at least one spring arm exerting an elastic retaining force on the base of the rail, and tensioning means for tensioning the spring element. Such a system allows an optimally secure support of the rail even in the case of a level ground having no indentations or stop shoulders, whilst being easy to handle and having only a small number of components to be mounted in each case, by providing a support angle which may be connected to the solid ground and which has a bearing surface against which the guide plate rests on the side facing away from the rail base. According to the invention the support angles are made from a plastic material, in order to facilitate assembly and improve the function of the support angles in practical use.

  • Patent number: 7744010
    Abstract: The present invention provides an isolator particularly adapted for use with a rail anchor utilized in an application where railroad rail is installed on concrete ties. The isolator protects the concrete tie from contact with the rail anchor caused by longitudinal movement of the rail due to train acceleration of deceleration or expansion and contraction due to temperature changes. In one embodiment, the isolator is comprised of a structural plastic material and includes a front face section and a rear face section. The front face section and rear face section each comprise a generally rectangular structure, having a top edge, bottom edge, and side edges. Top and bottom sections join the front face section and rear face section and form part of the isolator. The rail anchor also comprises a support section that extends from an intersection of the rear face section with the bottom section. The rail isolator is designed to be embedded in a concrete railroad tie.

  • Patent number: 7673810
    Abstract: A rail fastening clip is used with a rail clip support having a rail clip slot of the kind used in K plates. The rail clip is formed from a U shaped member made of metal plate having a base and two arms tapered from the base to their tips, with the arms being bent inwardly beyond the base in a large arc and the tips are bent back toward the base and oriented for contact with the foot of the rail. The base is adapted to fit in the K plate slot of the rail clip support. The base of the clip has a leading edge remote from the arms that contacts the upper interior surface of the support slot to form at least a line of contact with the upper interior surface of the slot. The line of contact is about 6 mm. The design overcomes the problem of rotation of the clip within the support slot and is a more cost effective clip than that currently used with K plates.
