  • 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.

  • Patent number: 4925094
    Abstract: A concrete railroad tie has rail seats defined by plates, which are made from stainless steel or other non-corrodable metal or plastic, cast into the top surface of the tie at the rail seats. The stiffness of the plates should be less than that of the concrete body of the tie and they should have smooth top faces so that they do not cause scuffing of associated rail pads on which the rails rest at the seats. Each plate may have lugs projecting from its underside for providing a mechanical connection with the body of the tie.

  • Patent number: 3957201
    Abstract: An improved anchor structure for use with concrete railroad ties. A modular base plate is cast into the concrete tie with integral upwardly projecting shoulders extending from the base plate which complement it to present a seat to support a steel railroad rail. An anchoring portion is also integral with each shoulder and extends downwardly to anchor the device in the tie. The shoulder also presents an opening for receiving a retaining spring clip. A resilient rubber or fiber pad is disposed on the seat between the rail and the base plate. The pad is characterized by laterally projecting tabs which abut the bridging portion on either side to preclude lateral movement of the pad. The retaining spring clip engages the rail base and also has a leg projecting through the opening. A curvilinear portion of the clip complementally engages an arcuate segment of the briding portion while a second leg is disposed in a groove presented by the bridging portion.
