  • Patent number: 8814058
    Abstract: The invention relates to a plastic screw plug (6) for attaching a rail to a sleeper, in particular concrete sleeper, having an essentially cylindrical plug body which has at the head end a stem region (7) which preferably adjoins a plug crown (8) toward the bottom, and in the continuation of which stem region (7) has an outer thread (9) with which it can be turned out of or into the sleeper, and is provided with an inner thread (10) underneath the stem region (7) in order to receive a sleeper screw. The intention is to improve such a plastic screw plug, in particular, with regard to its operating properties such as uniform application of force into the sleeper, simpler mounting and replaceability, reduction of the risk of fracturing, and additionally to permit it to be used in a variable way.

  • Patent number: 5332153
    Abstract: The retention value of a screw previously inserted into a wooden railroad tie is increased by an axially extending sleeve ( 20 ) having an external thread ( 24 ) and an internal thread (25). The thread revolutions of the internal thread (25) are offset axially by half (h) the thread pitch (H) of the external thread (24). Due to this offset of the threads, the screw is positioned in the sleeve so that its threads are located between the external thread revolutions affording a new retention, while the external thread (24) seats within the thread previously formed in the wooden railroad tie by the screw.

  • Patent number: 5096118
    Abstract: A toggle tie plate rail fastening system is described for securing rails to wood cross-ties. A wear plate is secured to the upper surface of each of the cross-ties adjacent each end thereof. Each of the wear plates has a plurality of tubular toggles secured thereto which extend downwardly therefrom and which are received by openings formed in the cross-tie. A tie plate is positioned on each of the wear plates and has a rail supported thereon held thereto by a pair of hold-down plates. Bolt members extend downwardly through the hold-down plates and the tie plates and are received by the toggle members. Tightening of the bolts causes the toggles to compress and to move in to gripping engagement with the cross-tie.
