  • Patent number: 6443169
    Abstract: The present invention 10 discloses a portable apparatus for rotatably maintaining a length of conduit 12 on an incline to allow an operator 16 to easily and thoroughly clean the conduit as he sprays a jet stream of liquid 24 into the conduit and rotates it manually to ensure the circumferential cleansing of the interior of the conduit. A pair of rows of rollers 14 are mounted on the top surface of the platform 36 surface upon which the conduit 12 revolves. The platform 36 is hingedly pivoted 42 at its midsection for folding. Multiple legs support the platform 36 on an incline, having a longer leg 26 having an A-frame shape and a shorter leg 58. Both legs 26, 58 are foldable and leg 26 is height adjustable. A rotatable pylon stop member 44 is positioned on the lower end of the platform 36 to retain conduit 12 on the platform 36. A slidable tray 46 is disposed on platform 36 for accepting longer conduits 12. A drive system 78 may also be provided to mechanically turn the rollers 14 and thereby the conduit 12.
