Abstract
A connector member for coupling flexible cylindrical tubular duct to the wall of a fibrous duct is comprised of a pair of parallel metal strips, the opposed marginal edges of which are connected to a flexible central strip. A clamp and a slip joint are provided on the respective strips for maintaining the metal strips in a cylindrical configuration, with the ends of the strips overlapping. One said strip including outwardly facing gaskets disposed at opposite sides of the wall of the fiber duct, the other strip including an inwardly facing gasket clamped about the flexible cylindrical ducting.
Claims4
A connector member for coupling a cylindrical flexible tubular duct to a wall of a fiber duct installation comprising an elongate band including a flexible central web assembly, a pair of sheet metal strips clampingly connected to the side marginal edges of said web assembly, said strips having an upper surface, an under surface and distal ends, said strips being disposed in parallel spaced relation, one said strip including on an upper surface thereof a spaced parallel pair of compressible gasket members extending upwardly beyond said surface, the spacing between said gasket members corresponding substantially to the thickness of said wall of said fiber duct, said one of said strips including at its distal ends interengageable complemental slip joint means for slidably connecting said distal ends in overlapping relation, the combination including complementary clamp means adjacent the distal ends of the other said strip for retaining said connector member in a cylindrical configuration.
