Pipe Coupling Apparatus

摘要

A pipe coupling apparatus adapted to allow for the connection of older, common sewer or drain pipe made of concrete, clay or the like to that of the newer style polymers such as ABS, CPCV, PVC and the like. It accomplishes this through a novel connection method that eliminates having to cut off the bell end of the older sewer or drain pipe and provides for a method of stabilizing the alignment of the two connected pipes. The apparatus incorporates a pipe coupling and a flexible polymer sleeve, and depending on the dimensions of the pipes involved, may require an optional seal ring. The assembly time is greatly reduced over the prior art methodologies and the coupled pipes are less likely to leak.

1. A pipe coupling apparatus adapted for the connection of non-dimensionally standardized pipes to dimensionally standardized pipes comprising:
a linear pipe coupling having an inlet section pipe length with a round inlet end connected to an outlet section pipe length with a round outlet end, said inlet end defining an inlet cross sectional diameter, and said outlet end defining an outlet cross sectional diameter smaller than said inlet cross section diameter, and wherein said inlet section pipe length has an inlet longitudinal axis that passes through a midpoint of said round inlet end, and wherein said outlet section pipe length has an outlet longitudinal axis that passes through a midpoint of said round outlet end, and wherein said inlet end and said outlet end are eccentric, not sharing a common longitudinal axis running though their respective section lengths, wherein said inlet longitudinal axis and said outlet longitudinal axis are not collinear.
