  • Patent number: 4130216
    Abstract: A novel peripheral seal for sealing a liquid storage tank of the type having welded, riveted, or bolted, cylindrically shaped side walls includes a floatable pontoon, and a plurality of seal support arms successively and radially disposed about the pontoon periphery. Each support arm is pivotally connected to a pontoon side. A plurality of arcuately shaped primary seals span from one support arm to the next successive support arm and are biased raidally outwardly to sealingly engage the riveted sidewalls. A fabric membrane spans from support arm to support arm and extends from a primary seal to the pontoon to form an annular cover. The support arms are interconnected by flexible connection means to provide stability, and limited circumferential movement thereof. The flexible connection means also allows each support arm to move radially inwardly and outwardly, by itself, to a certain degree.
