ABSTRACT:
A rail cutting apparatus including a base adapted to be disposed on the head of a rail. Opposed, inwardly directed fingers are located on the base for disposition about the head of the rail and the fingers on at least one side of the base are movable towards the opposed fingers. A clamp is provided to clamp the fingers about the head of a rail and a pair of links having adjacent ends pivotally interconnected for relative rotation about an axis generally parallel to the direction of elongation of the head of a rail are pivotally connected to the base for limited rotation about an axis parallel to the previously mentioned axis. A cutting tool is pivotally connected to one of the links remote from the base such that when the apparatus is clamped to a rail, the cutting tool may be swung to either side of the rail to cut the rail without removing the apparatus from the rail.
