  • Metal pipe coupling to accommodate a desired angle of connection between drainage pipe sections
    Patent number: 4865357
    Abstract: A rigid metal pipe coupling for joining pipe sections comprises a sheet of metal having opposite edges for rolling into a generally cylindrical rigid sleeve. The metal sheet has an integrally formed expansible and contractible means formed intermediate the ends of the sheet, said means is adapted after rolling into said sleeve and under the action of a predetermined force to expand and contract thereby allowing said sleeve to permanently bend and accommodate a desired angle of connection between pipe sections.
