Abstract
An expansion joint for ducts for high temperature gases has upstream and downstream members to be secured to spaced apart ends of corresponding duct sections. Each member has an outer flange, the outer flanges disposed towards each other and having a fabric cover secured thereto. The upstream member has an inner flange disposed towards the downstream member. A floating seal has right angular portions of which one overlaps the outer surface of the inner flange and the other overlaps the downstream member. Clips back each portion of the floating seal to hold them to provide a maximum clearance between the boundaries thereof. Resilient seals carried by the floating seal slidably engage the overlapped boundaries of the clearance.
