Trap and solids removal assembly for drains

In a drain trap assembly of the type having a vertical inlet leg adapted for connection to a plumbing facility to be drained, a vertical outlet leg adapted for connection to an outlet line to a drainage disposal, and an arcuate section connecting said legs, the improvement comprising:

• a cylindrical clean-out section integrally incorporated horizontally within said arcuate section, said cylindrical cleanout section having an axis lying substantially in a common plane with the axes of said vertical legs, said clean-out section extending from said arcuate section beyond said vertical inlet leg,
• means for sealing the end of said clean-out section extending beyond said inlet leg,
• filter means positioned in said clean-out section intermediate said inlet and outlet legs, said filter means being integrally connected to said sealing means,
• said sealing means and filter means being adapted for detachment and removal from said clean-out section, and wherein said inlet and outlet legs, arcuate section, and cylindrical clean-out section are comprised of injection molded thermoplastic.

An improved trap assembly of the type adapted for use on plumbing lines handling flowing liquids which contain solid particulate matter of the type having a tendency to accumulate in the trap and require periodic removal therefrom, comprising:

• a generally U-shaped trap having a vertical leg on each of the inlet and outlet sides of the trap and a substantially horizontal cylindrical base interconnecting said legs, said cylindrical base extending outwardly beyond the interconnection of said base with said vertical leg on the inlet side of the trap;
• a removable unitary sealing and filtering means including a sealing member adapted to seal the end of said cylindrical base which extends beyond said interconnection, a filtering member adapted to fit within said cylindrical base between said vertical legs, and a connecting member connecting said sealing member to said filtering member such that when said sealing member is removed from the trap said filtering member is simultaneously withdrawn outwardly therefrom, said filtering member being adapted to provide positive displacement and removal of any particulate matter which has accumulated between said filtering member and said sealing member when said unitary sealing and filtering means is removed from said cylindrical base, and wherein said cylindrical base also extends outwardly beyond the interconnection of said base with said vertical leg on the outlet side of said trap and wherein there is further included a removable sealing member adapted to seal the end of said cylindrical base which extends beyond the vertical leg on the outlet side of said trap.
