Tool for removing and tightening screw-on drains

A tool for inserting and removing a drain flange comprising:

• first means for driving a cam in both a counterclockwise and clockwise direction, said first means having a round shaft portion that has a predetermined diameter and a square shaft portion at a first end of said driver that has a diagonal, corner to corner measurement that does not exceed said predetermined diameter, and a square receptacle at a second end of said driver that is adapted to receive a socket wrench;
• second means for transferring a torque from said first means to said drain flange, said second means having an upper main body flange and a lower main body flange that are coupled via a main body support to form a slot between said upper main body flange and said lower main body flange, said upper main body flange having a round opening in which said round shaft portion of said driver fits and rotates, said main body having teeth disposed along predetermined portions of an outer surface of said main body;
• third means for transferring said torque from said first means to said drain flange, said third means having a thickness that allows said cam to be inserted and rotated in said slot, said cam having a square opening that is offset from a center point of said cam, said square opening being adapted to engage said square shaft portion of said driver so that said round shaft portion of said driver rotates in said round opening of said upper main body flange and rotates said cam between a closed position and an extended position relative to said main body, said cam having teeth to engage said drain flange in said extended position;
• fourth means for engaging an arm of drain flange and transferring said torque from said first means to said drain flange through said arm, said fourth means attached to said lower main body flange that is adapted to engage an arm of said drain flange and exert a clockwise force on said arm whenever said driver creates a clockwise torque so that said cam is forced against said main body support and said main body rotates in a clockwise direction in said drain flange around said nub until a smooth section of said main body portion rests against an inner surface of said drain flange, and exerts a force on said arm in counterclockwise direction whenever said driver creates a counterclockwise torque so that said main body portion rotates in a counterclockwise direction in said drain flange around said nub until said teeth on said main body portion engage an inner surface of said drain flange and said cam is rotated to said extended position so that said teeth on said cam engage said inner surface of said drain flange.

A tool for inserting and removing drain flanges comprising:

• a driver having an upper rounded portion and a lower rounded portion;
• a main body having an upper main body flange and a lower main body flange that are coupled via a main body support to form a slot between said upper main body flange and said lower main body flange, said upper main body flange having an upper rounded opening that is sufficiently large to allow insertion and rotation of said upper rounded portion, said lower main body flange having a lower rounded opening that is sufficiently large to allow insertion and rotation of said lower rounded portion, said main body having a functional surface disposed at least along predetermined portions of an outer surface of said main body;
• and,
• a cam having a thickness that allows said cam to be inserted and rotated in said slot, said cam attached to said driver in a position that is offset from a center point of said cam so that said cam rotates between a closed position and an extended position relative to said main body, said cam having a frictional surface that engages said drain flange.
