Branch tail piece

A waste water drainage system comprising in combination, a sink strainer for draining waste water from a sink, conduit means for conducting waste water from a dishwasher or the like, a trap associated with a waste drain, and a branch tail piece comprising a hollow tubular body portion, a hollow tubular branch member, and a baffle, said body portion having an upper sink strainer engaging end including means for coupling said tail piece to said sink strainer and a lower trap engaging end adapted to engage said trap, said branch member extending outwardly from said body portion and having an inlet port and an outlet port, said outlet port communicating with the interior of said body portion, said branch member including means for coupling said inlet port to said conduit means, said baffle being positioned within said body portion adjacent said outlet port to provide a channeled flow path for directing the flow of the waste water within said tail piece to prevent the waste water from being expelled from said sink strainer, said baffle comprising a planar portion and an arcuate portion, said planar portion extending chordwise across the interior of said body portion, the lower edge of said planar portion extending at least as far as a line projected along the inner surface of said branch member such that said baffle extends at least as far as a line projected along the inner surface of said branch member such that said baffle extends at least across said branch member outlet part, said arcuate portion extending across the interior of said body portion, the lower end of said arcuate portion being attached to the upper edge of said planar portion, the upper edge of said arcuate portion being attached to the inner wall of said body portion between said outlet port and said sink strainer engaging end, whereby said baffle deflects downwardly the hot waste water from the dishwasher and dissipates the heat, thus protecting the body portion of said tail piece from damage.
