ABSTRACT:
A vacuum operated refuse collecting vehicle includes an air-tight container mounted on the chassis of the vehicle and having an outlet communicating with means for generating a vacuum within the container. A suction conduit is provided for each side of the vehicle, each suction conduit extending at one end into the interior of the container and being provided at the other end with a nozzle which may be disposed at a short distance from the ground. Brrush means are provided. Means are mouned at said one end of each conduit which are operable from outside the container, for separately closing off said one end of each suction conduit to prevent refuse entering said one end of the conduit when it is closed. Said one ends of said suction conduits communicate with the container in positions one on each side of a central longitudinal plane of the container and adjacent one end of the container. Said outlet is positioned in the upper part of the container adjacent the other end of the container and continuously curved deflector means are provided above said one end of each suction conduit. The arrangement is such that, in use, with one suction conduit open and the other closed, air entering the container through said one of the suction conduits is diverted by the respective deflector means up around the upper part of the container and down towards the central lower part of the container before passing out through the outlet, to prevent refuse being deposited on and around said one end of said other suction conduit.
