Abstract:

A toilet water-line filter ( ) that is designed to protect a toilets fill valve ( ) from the intrusion of potentially damaging debris such as rocks, vegetation, etc. The filter ( ) is comprised of a housing ( ) and an internal filter ( ) which consists of a mesh staining element ( ). The filter ( ) is attached between the toilets fill valve ( ) and a typical, flexible, water line ( ). Debris that would normally pass into the fill valve ( ) becomes trapped in the mesh staining element ( ), from where the debris is easily removed.

Abstract:

A piston flush valve (10) that is installed in a toilet tank (150) and that operates in combination with a ballcock supply valve (152), a trip lever(154) and a refill tube (158). The piston flush valve (10) includes an upper section (12) which is movably attached to a lower section (72) that is attached to a water egress port (160) located on the bottom of the toilet tank(150). The upper section (12) includes an overflow tube (14) which has a vertical series of outwardly extending slots (24). The slots (24) function in combination with a flush-volume spring clip (58) that is attached to a float (44). The spring clip (58) has a notch (60) sized to fit into one of the slots (24). Depending on which slot (24) the notch (60) is inserted will determine the amount of flush water the toilet tank (150) delivers to the toilet bowl (162).

International Classification:

E03D 106

US Classification:

4344

Abstract:

A universal replacement toilet tank (10) that incorporates within a toilet tank (12) a piston flush valve (40) that functions in combination with a ballcock (22), a water closet (30) and a pressure increasing riser (120). The valve (40) is designed to be easily adjusted to allow a selected volume of flush water to flow from the toilet tank (12) into the water closet (30). The pressure increasing riser (120) consists of a hollow pipe (122) and a decorative sleeve (140) that are positioned between the toilet tank (12) and the water closet (30). The riser allows the toilet tank (12) to be elevated above the water closet (30) to provide an increase in the pressure of the water that is used to flush the water closet (30). The invention also includes a threaded adapter (100) having upward internal threads (102) and downward external threads (104). The internal threads (102) are threaded into the threaded section (96) on the flush valve attachment structure (84) and the external threads (104) are inserted through a water egress port (24) on the toilet tank (12).

International Classification:

E03D 500

US Classification:

4344

Abstract:

A dual power-flush toilet (20) which has a water closet (22), a water tank (24), a ball cock (26), and a first lever arm (28). A dual acting flush valve (30) is disposed within the tank and modified to incorporate an overflow opening (44), a refill elbow (46) and a beveled washer (32). A second tank lever arm (50) is installed into the tank and lifts the flush valves vertical tube (36) causing a partial flush of the water in the tank. The first tank lever arm is attached to the flush valves float assist arm (38) beneath the second lever arm lifting both the vertical tube and float assist (40) delaying the opening until a complete flush of the water from the tank is achieved. A pressure increasing riser (56) is added between the water closet and the water tank to boost the water pressure and more efficiently flush water from the tank into the water closet.
