Adjustable drain control assembly

Claim 2

An adjustable drain control assembly comprising a hollow cylindrical component having an external flange in proximity to one end thereof to divide said component into a long section and a short section, said short section having peripheral notches in the edge thereof, leaving intervening peripheral ridges, segments extending from said peripheral ridges and merging to define openings between them which, with the peripheral notches in the edge of said short section, establish enlarged passageways into said cylindrical component having a total flow capacity of the order of that of said cylindrical component, a cap spanning the end of said shorter section and including a cylindrical flange surrounding said notched rim in sliding relationship thereto, said cap inclusive of its cylindrical flange, having openings simultaneously alignable with the openings forming said enlarged passageways, and means rotatably securing said cap in its position over the end of said shorter section, said means for rotatably securing said cap over the end of such shorter section including a peripheral channel formed externally in the notched edge of said shorter section and an inwardly directed flange on said cap meshing with said channel in slidable relationship with the walls thereof.

Claim 3

An adjustable drain control assembly comprising a hollow cylindrical component having an external flange in proximity to one end thereof to divide said component into a long section and a short section, said short section having spaced peripheral notches in the edge thereof, leaving intervening peripheral ridges, segments extending from said peripheral ridges and merging to define openings between them which, with the peripheral notches in the edge of said short section, establish enlarged passageways into said cylindrical components having a total flow capacity of the order of that of said cylindrical component, a cap spanning the end of said shorter section and including a cylindrical flange surrounding said notched rim in sliding relationship thereto, said cap inclusive of its cylindrical flange, having openings simultaneously alignable with the openings forming said enlarged passageways, means rotatably securing said cap in its position over the end of said shorter section, and means for installing said drain control assembly in a tub drain, said means for installing said drain control in a tub drain, including a thread on the long section of said cylindrical component, and a tool comprising a bar having a pair of depending stubs spaced apart a distance equal to the internal diameter of said cylindrical component and adapted to pass through openings in said cap and into notch openings in the edge of said shorter section, whereby said tool stubs will engage end wall areas of proximate ridges upon rotation of said tool and thus facilitate screwing or unscrewing of said drain control into or out of a drain fitting.

Claim 4

An adjustable drain control assembly comprising a hollow cylindrical component having an external flange in proximity to one end thereof to divide said component into a long section and a short section, said short section having spaced peripheral notches in the edge thereof, leaving intervening peripheral ridges, segments extending from said peripheral ridges and merging to define openings between them which, with the peripheral notches in the edge of said short section, establish enlarged passageways into said cylindrical components having a total flow capacity of the order of that of said cylindrical component, a cap spanning the end of said shorter section and including a cylindrical flange surrounding said notched rim in sliding relationship thereto, said cap inclusive of its cylindrical flange, having openings simultaneously alignable with the openings forming said enlarged passageways, means rotatably securing said cap in its position over the end of said shorter section, and means for installing said drain control assembly in a tub drain, said means for installing said drain control in a tub drain, including a thread on the long section of said cylindrical component, and a tool comprising a bar having a pair of depending stubs spaced apart a distance equal to the internal diameter of said cylindrical component and adapted to pass through openings in said cap and into notch openings in the edge of said shorter section, whereby said tool stubs will engage end wall areas of proximate ridges upon rotation of said tool and thus facilitate screwing or unscrewing of said drain control into or out of a drain fitting.
