Abstract: A closet flange with a body portion having a tapered end and a plurality of grooves circumferentially disposed about the tapered end. The grooves increase in diameter in the upstream direction and are configured to receive an elastic O-ring. As the closet flange is inserted into a drain pipe the O-ring travels from groove to groove providing an increasingly tighter fit. The flange is installed without tools by pushing the flange into the end of the pipe until the desired tightness is achieved.

Abstract: A ratchet type closet flange for replacing broken cast iron closet flanges in old buildings or in new construction in place of conventional cast iron closet flanges. The patented invention comprising a flange body, a cup, a rubber seal, and a means for applying pressure. After removing the broken closet flange, the ratchet type closet flange is inserted into the existing pipe. A compression seal is formed between the flange body and the inside of the pipe by applying pressure to the flange body and the cup, forcing a compression seal between the rubber seal and the pipe. The ratchet type closet flange may slide up and down inside the pipe to achieve the desired height.

Abstract: A reusable concrete spacer sleeve comprises a substantially cylindrical body having a plurality of inwardly extending fins. The sleeve is placed over a vertical drain pipe prior to pouring a concrete floor. After the concrete has set, the sleeve is removed, leaving an annular space around the pipe for accommodating a flange. A lid may be fitted onto the sleeve to prevent debris or other foreign matter from entering the pipe or the annular space around the pipe.

Abstract: A street compression closet flange for replacing broken cast iron closet flanges in old buildings comprises an upper cylindrical section, a lower cylindrical section, a rubber seal, and three sets of nuts and bolts. After the broken closet flange has been removed, the street flange is inserted inside the existing pipe. A compression seal if formed between the street flange and the inside of the pipe by tightening the nuts and bolts. The street flange may be slid up or down to achieve the desired height. The street flange may also be used in new building construction instead of conventional closet flanges.
