<p>The inner end (98) of a snake or drain cleaning cable (70) coiled in a rotatable cable storage drum (14) of drain cleaning apparatus (10) is provided with a torque arm (100) which frictionally engages the outer wall (86) of the drum (14) to restrain sliding of the cable (70) relative thereto during a drain cleaning operation. The drain cleaning apparatus (10) is motor driven, and a cable feed device (122) for axially displacing the cable (70) relative to the storage drum is provided on the outer end of a flexible guide tube (196) detachably mounted on the apparatus (10) to facilitate an operator guiding the outer end of the cable (70) into a drain to be cleaned and advancing or retracting the cable (70) relative to the apparatus without having to physically contact the cable (70). <IMAGE></p> |
