Abstract
Abstract This device consists primarily of a coupling sleeve for a sewer pipe, and on the interior of the coupling sleeve is supported a cup or well, and on the interior of the cup is supported, a funnel tube beneath a water strainer. The water flows through the strainer, down through the funnel tube, upwards out of the cup portion, and finally, down the open end of the coupling sleeve, into the sewer pipe.

Claim 1
Independent Claim
287 words
A basement sewer trap, comprising in combination, a cylindrical coupler sleeve, a radially inwardly flange on an inner face of said sleeve located along an intermediate portion of said inner face, a portion of said inner face below said flange fitting around an upper end of a sewer pipe, a portion of said inner face above said flange fitting an outer periphery of a cylindrical ring of a plastic cup which is supported on said coupler sleeve inward flange, said plastic cup including a cylindrical side wall, a circular bottom wall at a lower end of said cup side, and said ring being concentrically spaced around an upper edge of said cup, said plastic cup depending downwardly into a center of an upper end of said sewer pipe, said cup ring being joined with said cup side wall by a pair of diametrically spaced apart webs therebetween, a funnel tube of cylindrical shape being concentrically within said cup, an upper edge of said funnel tube being integral with a radially outwardly conically-shaped flange which at its outer periphery fits said inner face of said coupler sleeve and rests upon an upper edge of said cup ring, and an upper end of said coupler sleeve having a circular recess in which is fitted a circular water strainer having a plurality of openings therethrough, for drain water to pass therethrough, then down through said funnel tube, then up in said cup around an outer side of said funnel tube, then over a top of said cup and down through spaces between said cup side wall and said cup ring so as to flow down around an outer side of said cup side wall and down into said sewer pipe.
