Abstract: A vacuum refuse collecting vehicle has a tank divided into two hermetically sealed compartments by an internal sloped wall. The forward compartment functions as a water tank and the rear compartment as a waste containment tank. The capacity of the compartments can be increased by the addition of spacers to the cylindrical tank to make the tank longer, by changing the angle of the internal sloped wall, or by changing the depth of the concave end walls of the tank. The rear compartment is equipped with an upwardly tilting hinged concave tail gate for emptying the waste therefrom. The airstream which deposits the waste material in the tank is directed out of the tank into one or more bag filter housings, through an air pump, a silencer, and then to the surrounding atmosphere. The bag filters are so mounted and constructed that they may be removed through the bottom of the housings, thereby maintaining the upper portions of the housings substantially free of waste material.

Abstract: A liquid extraction surface cleaning apparatus has an upwardly opening recovery tank and a top for the tank which contains a suction fan having a suction inlet opening into the tank. A wand connects to a source of cleaning liquid and has a dispensing and pickup head that deposits liquid on the surface to be cleaned in response to actuation of a control valve and picks up dirty fluid. A water and air separator has an arcuate surface transverse of the flow path of the air and spent liquid which gently separates them into separate streams by diverting the cleaning liquid laterally away from the air stream. A shutoff valve for preventing recovered liquid in the tank from entering the suction fan is mounted in the recovery tank rather than to the suction inlet to avoid dripping dirty liquid onto the floor when the cover is removed. A handle is mounted internal the tank and additionally serves to strengthen the tank sidewalls.

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.
