  • Patent number: 4108477
    Abstract: A waste drain connection for independently-supported plumbing fixtures including a pipe with two open ends and a pair or radially-extending arms having open portions therethrough secured to the outside of the pipe intermediate the open ends thereof. A receptacle mounted to the plumbing fixture drain outlet is adapted to receive a fluid sealing gasket. Mounted to the plumbing fixture about the receptacle are two, oppositely-disposed threaded studs. The studs are arranged to be alignable with the pair of open portions in the arms of the pipe. A pair of nuts threadably engaged over the ends of the studs following mating thereof with the open portioned arms to move one of the ends of the pipe into sealing engagement with the gasket. A standard no-hub connection is used to couple the other end of the pipe to the plumbing drain.
