  • Patent number: 6913293
    Abstract: A pipe joint apparatus and method using spiral groove halves formed on the nested surfaces of male and female pipe ends. The exterior half of the spiral groove is connected to an exit port. The interior half of the spiral groove has a proximal end recessed from edge of its pipe. Alignment of the pipes and partial insertion of the spline allows for a threaded pipe connection that may be screwed or unscrewed to overcome the pressure for the gasket seal. Full insertion of the spline to engage the exit port locks the spline in position and the interior half's proximal end prohibits the unscrewing of the pipe joint. The pipe ends may be easily disconnected by pulling the spline out of the exit port to unscrew the pipe sections or fully removing the spline to separate the pipe ends. A gasket is used to form a sealed joint.
