ABSTRACT:
A sweeping machine has a wheel supported body and a rotatable brush mounted transversely of the direction of machine movement. There is a debris hopper adjacent the brush and a dust collection chamber on the body. A vacuum fan draws dust laden air from the area about the brush, through the debris hopper, and into the dust collection chamber. The improvement comprises a dust control side skirt assembly mounted on each side of the body generally in alignment with the brush. Each such assembly includes a flexible inner skirt and a flexible outer skirt spaced from the inner skirt. A flexible spacer extends between and is attached to the inner and outer skirts, with the spacer and skirts defining a cavity which has an air opening at a lower portion of the side skirt assembly. The air opening is formed by a discontinuity in the spacer. There is an opening in the inner skirt connecting the cavity with the area about the brush whereby the vacuum fan creates an airflow path through the air opening, into the cavity, through the inner skirt opening and into the debris hopper and dust collection chamber.
