ABSTRACT:
This invention relates to rail anchorages that are used with all rails, but is particularly concerned with adjustable rail anchorages, which allow rail alignment to be adjusted, and which are installed on rails used by cranes. To reduce this rail movement and to help limit vertical uplift of the rail, pressure is applied to the rail flange by resilient material attached to the part of the rail anchorage that overhangs the rail flange. The object of this invention is to provide support to the resilient material in a way that its length can be increased from the bonded surface or outside of the pocket in which it is installed. The invention allows for a greater variation in rail size and rail elevation that can be accommodated with one rail anchorage type and differing lengths of the resilient material. Please refer to FIG. 12 in the accompanying drawings.
