ABSTRACT:
An expansible dry seal gasholder includes a piston disposed within a container side wall and a plurality of generally annular fender structures disposed between the piston and the side wall and spaced therefrom and from each other, with flexible fabric sealing members interconnecting the piston and the fender structures and the side wall and closing the spaces therebetween. Respectively pivotally mounted between the arms of a clevis at the top of each fender structure are generally L-shaped latch members, each having one end thereof connected by a roller chain to the upper end of the next innermost fender structure, with the latch member of the innermost fender structure being connected to the upper end of the piston. The clevis brackets are adjustable effectively to vary the lengths of the chains. Each latch member has an adjustable-length arm which is pivoted by the action of the associated chain into engagement with the adjacent fender structure or piston to which that chain is connected when that adjacent fender structure or piston has been raised above said latch member to the point where the chain is fully extended.
