Closet fitting

Abstract

A water closet fitting including an annular flange, a cylindrical sleeve attached and extending outward of the flange, and a removable seal for temporarily sealing the closet fitting during construction and volumetric pressure testing of a drainage system to which the closet fitting is connected. The closet fitting prevents material during construction of the drainage system from falling into the drainage system and obstructing it.

It is claimed:  
     
         1 . A closet flange comprising: 
 an open upper end, an open lower end and a wall extending between said upper end and said lower end forming a passageway between said upper end and said lower end;    a removable lid having an upper surface and a lower surface positioned in said passageway for sealing said passageway, said lower surface being in direct communication with said lower end and said upper surface being in direct communication with said upper end,    a break-line extending around a periphery of said lid outward of said wall, and    a tab extending from said upper surface with one end of said tab positioned approximately over said break-line,    wherein said tab is constructed and arranged to break said break-line to allow removal of said lid through said upper end.    
     
     
         2 . A closet flange in accordance with  claim 1  wherein said break-line can withstand a pressure of at least 5 psi applied against said lower surface of said lid without breaking and unsealing said passageway.  
     
     
         3 . A closet flange in accordance with  claim 1  further comprising a rim for connecting said lid to said wall.  
     
     
         4 . A closet flange in accordance with  claim 3  wherein a portion of said rim is embedded within said wall.  
     
     
         5 . A closet flange in accordance with  claim 1  wherein said lid is positioned adjacent to said upper end.  
     
     
         6 . A closet flange in accordance with  claim 1  wherein said lid is positioned adjacent to said lower end.  
     
     
         7 . A water closet fitting comprising: 
 a flange having an upper surface and a lower surface,    an opening through said flange defined by a tapered wall extending between said upper surface and said lower surface,    a cylindrical sleeve extending outward from said flange having a passageway therethrough aligned with said opening,    a seal having a top surface and a bottom surface for temporarily closing said passageway, said seal having an outer rim and an inner removable lid separated by a break-line, and    a tab attached to said top surface of said lid and positioned in relation to said break-line so as to allow breaking of said break-line upon movement of the tab.    
     
     
         8 . A closet fitting in accordance with  claim 7  wherein said rim is embedded in said sleeve.  
     
     
         9 . A closet fitting in accordance with  claim 7  wherein said rim is embedded in said tapered wall.  
     
     
         10 . A closet fitting in accordance with  claim 7  wherein said bottom surface of said lid can withstand a pressure of at least 5 psi applied there against without disconnecting said lid from said rim.
