Abstract
A drain-cleaning device adapted to unclog drains and pipes having various sized openings and toilet bowls having various outlet configurations, the device comprising an inverted flexible and resilient cup defined by a dome-shaped inner wall surface and an outer annular wall surface which includes a plurality of contiguous annular rim members, each being formed with a predetermined diameter to fit a corresponding drain or pipe opening when placed thereover, the cup being adapted to receive water therethrough under pressure, and the device further including a bulbous plug fitting adapted to be secured to the central opening disposed in the cup member so as to protrude outwardly therefrom in order to be directly received in a corresponding opening, whereby the opening can be sealed by the plunger as water passes therethrough.
Claims3
A water-pressure, drain-cleaning device in combination with a water hose comprising:
- a cup-like body member having an outer ringed wall and an inner arcuate domed wall;
- an inner cup chamber defined by said inner arcuate domed wall and an annular lip member formed at the terminating annular edge of said inner arcuate wall;
- said outer ringed wall defined by a plurality of annular rim members arranged contiguously to each other, each having a different size diameter defining sealing means when disposed over a corresponding opening of a drain;
- wherein each of said annular rim members includes a flat sealing surface and an inclined sealing surface for positive sealing engagement with said drain opening;
- said cup-like body including a central bore communicating with said cup chamber, said bore having a threaded sleeve member affixed therein to removably receive said water hose therein from either side of said sleeve member;
- and
- a removable plug fitting having an inlet port and an outlet port, said inlet port being adapted to be secured to said threaded sleeve member of said cup body, said plug fitting being formed from a resilient material so as to expand under water pressure, whereby said plug fitting conforms to the configuration of said adjacent drain opening.
