I would like to congratulate my client Edward Underhill, president of UNDERHILL INTERNATIONAL CORPORATION, of Irvine, California for obtaining a patent on his “Extender”, a device used in underground water supply systems, for example, for irrigating golf courses, a vertical distribution supply pipe extends vertically below-ground and is coupled at its lower end to a main water distribution pipe. The opposite end of
the vertically disposed distribution pipe is coupled with quick coupler assembly that is at ground level and includes a quick connect valve. The quick connect valve has a cap and a cover. To open the valve to supply water to an above-ground distribution conduit, for example, a hose, the cover is removed and the valve cap is pivoted out of the way.
The patent can be seen here.
