ABSTRACT:
A street sweeping machine is incorporated in an industrial vacuum machine. Extending transversely of the vehicle is a center casing in which a brush is rotated by a hydraulic motor. A vacuum intake hose is connected to the casing and leads to the vacuum machine. The casing may be raised and lowered between transport and working positions. On one or both sides of the vehicle are side or "curb sweeping" casings, likewise containing a hydraulically driven brush and connected to a vacuum intake hose. The curb sweeping casing is swivel mounted and spring biased outward to follow the curb on the street being swept. In the main centered casing are a hydraulically raised and lowered flap which improves the vacuum which can be drawn in the casing. Also provided is a stick breaker which breaks up large pieces of debris so that they may be drawn into the vacuum duct.
