Abstract
Drain cleaning apparatus comprises a housing in which a drain cleaning cable is coiled and from which the cable is displaced for introducing an outer end of the cable into a drain to be cleaned. The housing is stationary and the cable is rotated about its axis relative to the housing by a drive motor coupled to an inner end of the cable. A manually operable cable feeding device can be coupled with the housing for feeding the cable outwardly and inwardly relative to the housing.
Claims53
Drain cleaning apparatus comprising, a housing having a cable opening, a drain cleaning cable coiled in said housing about a coil axis and having a cable axis transverse to the coil axis and first and second ends, said second end extending outwardly through said cable opening, and a motor in the housing operatively connected to said first end of said cable for rotating said cable about said cable axis relative to the housing without rotating the housing.
Drain cleaning apparatus comprising, a housing having a cable opening, a drain cleaning cable having a cable axis and first and second ends, said second end extending outwardly through said cable opening, means for feeding the coiled cable outwardly and inwardly through said cable opening in response to rotation of said cable and means for rotating said cable including said first end about said cable axis relative to the housing, wherein said cable is coiled in said housing about a coil axis transverse to said cable axis and wherein said housing includes an outer shell having a shell axis and an inner wall spaced inwardly therefrom, said cable opening being in said outer shell, and said cable being coiled about said inner wall.
Drain cleaning apparatus comprising, a housing including an annular cable housing having radially spaced apart inner and outer walls providing a cable passageway therebetween having lower and upper ends, said outer wall having a cable opening therethrough, a drain cleaning cable having a cable axis and an inner end in said housing, said cable being coiled about said inner wall and extending outwardly through said cable opening, and a motor in said housing coupled to said inner end of the cable for rotating the cable, including the inner end thereof, about said cable axis relative to said housing without rotating said cable housing.
Drain cleaning apparatus, comprising a housing having a base and a cover, said base having a first base portion including an annular wall extending upwardly therefrom and a domed wall extending upwardly and radially inwardly from said annular wall, said base having a second base portion extending laterally of said first base portion, said cover having a first cover portion including an annular wall and domed wall respectively radially spaced from and overlying the annular wall and domed wall of said first base portion, said cover further including a second cover portion overlying said second base portion, an electric motor between the second portions of the base and cover, a drain cleaning cable having a cable axis, said cable being coiled about said annular wall of the first base portion and having an inner end coupled to said motor for said motor to rotate said cable about said cable axis relative to said housing, said domed wall of said first cover portion having a cable opening therethrough, and said cable extending outwardly through said opening and having an outer end spaced therefrom.
