ABSTRACT:
A device for sealing the rim space between a floating cover, movably disposed within a storage tank, and the inner wall of the storage tank. The device includes a peripheral sealing ring formed of a plurality of overlapped shoe segments, each segment having a first and second opposed edge to overlap with adjacent segments. Countersunk apertures are provided in each shoe segment, one aperture near the first edge. A fastener extends through each aperture so that a head of the fastener will reside within a recess formed by the countersunk aperture. At least one movable rod extends past the first edge. A clip for each fastener has a space for slidably receiving the rod, each second side free to slidably overlap the first side and the fastener.
