  • Publication number: 20100101446
    Abstract: A railway anchor applicator for applying an anchor to a rail includes a frame configured for movement along a track, an anchor input for sequentially delivering an anchor to a workhead assembly, where the workhead assembly is movably mounted on the frame for movement toward and away from the rail. An anchor receiving arm is configured for movement between a first position receiving an anchor from an anchor input and a second position placing the anchor away from the anchor input. A main pivot arm is configured for movement between a first position generally away from the rail and a second position generally adjacent the rail. A bar clamp arm is operatively linked to the main pivot arm and is configured for movement underneath the rail, then upwards and towards the rail. An operator station is located on the gage side of the rail which the anchor is being applied.

  • Patent number: 7647871
    Abstract: A railway anchor applicator for applying an anchor to a rail includes a frame configured for movement in a specified direction of travel along a track, and a workhead assembly movably mounted on the frame for movement toward and away from the rail. Also provided is an anchor receiving mechanism configured for movement between a first position receiving an anchor from an anchor input and a second position placing the anchor away from the anchor input. An anchor positioning mechanism moves between a retracted and extended position for positioning the anchor adjacent to the rail at either the field or gage side of the rail. An anchor clipping mechanism engages the anchor onto the rail by applying pressure on the anchor from the side of the rail and compresses the anchor between components of the anchor clipping mechanism so that compressive forces act on the anchor transversely across the rail.

  • Patent number: 7104200
    Abstract: A rail fastener driver apparatus for driving fasteners into ties of a railroad track includes a fastener driving mechanism with a reciprocating element for engaging a fastener and driving it into a tie, a fastener magazine configured for accommodating a plurality of rail fasteners and feeding them sequentially for driving by the element, a fastener feeder mechanism including a fastener holder configured for movement between a first position sequentially receiving one fastener from the magazine and a second position placing the fastener in a driving position for engagement by the driving element and the fastener feeder mechanism configured for lowering and axially rotating the fastener from the first position to the second position. An obstacle accommodation device, and a method of driving rail fasteners are also provided.
