ABSTRACT:
The space saving double seal uses a lower shoe, an upper shoe and a pair of vapor barriers joining them to a conventional outer rim plate on a floating roof. The secondary vapor barrier extends from the outer rim plate to the top of the upper shoe. A pair of pusher springs maintain the shoes against the tank's inner wall. The invention provides for liquid storage to the full height which the floating roof allows. Additionally an improved primary and/or secondary shoe leaf spring and pusher brace combination improves the seal between the shoe and the inner wall.
