  • Patent number: 5884359
    Abstract: A pavement sweeping apparatus includes an angled, counter-rotating transverse roller broom followed by a high pressure/high velocity and full-width blast of air to remove particles too small for the broom to sweep up. The roller shaped broom has auger wound bristles causing dynamic propulsion of objects that come in contact with the surface of the rotating broom. The objects are forced by mechanical action, both by the windrow effect of the transverse angle of the broom and, additionally, by the augering action of the helical wound broom bristles to propel object toward an exhaust port of the powerhood for further transfer into a storage bin.
