Abstract: A mobile apparatus for cleaning sewers, catch basins and the like includes a debris collection chamber mounted on the rear of a vehicular chassis. A vacuum conduit communicates with the chamber and is adapted to be lowered into the sewer. A vacuum fan also communicates with the chamber and draws air through the conduit and chamber thereby picking up debris from the sewer. As the debris enters the chamber, the configuration thereof creates a rapid decrease in the air flow velocity and otherwise interrupts the flow so that material entrained in the air is deposited in the chamber. The configuration of the chamber also permits facile discharge of the debris out of the bottom of the chamber in that one end wall of the chamber is swingable to open the bottom thereof. This same end wall also carries a hose reel for use in flushing the sewer. Because the debris which is picked up may well include water, means are provided to drain the water from the chamber.

Abstract: A hose reel, particularly suitable for use with a mobile sewer cleaner, includes a cylindrical drum rotatable on a generally horizontal axis. A plate is affixed to each end of the drum to form the hose reel which is divided generally centrally by a third plate thus defining two hose receiving areas. Two hoses, preferably of differing diameters, are coiled on the reel, one hose in each hose receiving area. Fluid under pressure is provided internally of the reel through a pipe on the axis of rotation of the drum and is selectively channeled to at least one of two hoses coiled on the drum. In this manner, a single hose reel can be operated with different volume outputs dependent on the particular job being accomplished.
