  • Patent number: 6997419
    Abstract: An adjustable gage plate assembly having a pair of gage plate ends each with rail seats that are connected at their inner ends to swivel slide plates of an adjustment assembly which enables the gage plate ends to be moved laterally and angularily relative to each other such that the gage plate assembly may be adjusted to a specified lateral distance and angle between the gage plate end rail seats.

  • Patent number: 6517008
    Abstract: A rail brace assembly provides positive support for a stock rail mounted on a switch brace plate. The assembly includes a rail brace having a generally central opening that it is installed over a fixed clip housing attached to the brace plate. The clip housing accepts a resilient clip that secures the rail brace in position on the brace plate and against the stock rail. The resilient clip provides spring force directly to the rail brace in both a vertically downward direction and a lateral direction. The rail brace has a lug to prevent the clip from being removed from the clip housing due to vibration. The clip housing prevents the brace from moving laterally even if the clip breaks or becomes disengaged. The brace assembly includes a stop that is secured to the brace plate and a tapered wedge that is disposed between the stop and the rail brace. Upon driving the wedge longitudinally of the rail, lateral force is applied to the rail brace and the rail.
