CA 2237813

An improved drain cable apparatus (10) is provided which facilitates clearing of clogged drainpipes (16) while providing a way to readily determine whether the drainpipe (16) has been cleared, without the necessity of withdrawing the drain cable (70) from the drainpipe (16). The apparatus (10) includes a tubular main body (12) adapted for connection via a sleeve (34) to the drain pipe (16); the main body (12) is equipped with internal drain cable-cleaning sponge elements (32), as well as an apertured end cap member (18) permitting insertion of the drain cable (70). Structure (20) for determining when the drainpipe (16) has been cleared includes a water inlet (48) and a spaced water outlet (54) arranged so that water delivered to the main body (12) passes outwardly through the outlet (54) while the drainpipe (16) remains clogged, but allows such water to pass through the drainpipe (16) when the latter is clear. In this fashion the user can readily determine when the drainpipe (16) is inclogged by visually observing water flow from the outlet.

L'invention porte sur un appareil (10) à câble pour conduit d'évacuation amélioré facilitant la désobstruction de conduits d'évacuation bouchés (16) tout en donnant la possibilité de vérifier aisément si le conduit est désobstrué sans devoir retirer le câble (70) du conduit (16). L'appareil (10) comporte un corps principal tubulaire (12) conçu pour être raccordé, à l'aide d'un manchon (34), au conduit d'évacuation (16), ce corps principal (12) étant équipé d'éléments spongieux (32) internes de nettoyage fixés autour du câble pour conduit d'évacuation, ainsi que d'un obturateur d'extrémité (18) pourvu d'un orifice autorisant l'insertion du câble (70) pour conduit d'évacuation. Une structure (20), destinée à vérifier si le conduit d'évacuation (16) s'est désobstrué, comprend une admission d'eau (48) et une sortie d'eau (54), distinctes et agencées de manière à ce que l'eau amenée dans le corps principal (12) s'évacue par la sortie d'eau (54) tant que le conduit d'évacuation (16) reste bouché, mais passe dans le conduit d'évacuation (16) lorsque celui-ci est désobstrué. L'utilisateur est, de la sorte, en mesure de constater si le conduit d'évacuation (16) est désobstrué en voyant l'eau s'écouler ou non par l'orifice de sortie.
