  • Patent number: 4502189
    Abstract: A coupling for pipe or the like made up of a plurality of spaced generally hollow cylindrical bodies made of sheet material and each having their adjacent ends bent back on themselves forming a pocket along each edge, an outrigger bar extends through the pocket on one edge of each of the bodies and a short bar extends through the pocket on the outer edge of each body. The short bars are connected to the outrigger by means of bolts and a flexible liner is supported inside each of the bodies forming a gasket for surrounding a pipe extending through the bodies. In the second embodiment a basic difference is that the couplings are made up of clamps or outrigger clamps at two halves rather than in a single band.
