Patent attributes
A rotary broom assembly is provided for use with a vehicle to reduce the accumulation of ice and snow on the rotary broom assembly when clearing paved surfaces, such as airport runways. The rotary broom assembly includes one or more wiper assemblies that are mounted for reciprocating movement along a broom hood. The broom hood includes a generally flat top surface and the wiper assemblies move along the top surface to clear snow and ice from the top surface of the broom hood. During forward movement of the wiper blade, the scraping edge of the wiper blade contacts the top surface of the broom hood to remove accumulated ice and snow. During the reverse movement of the wiper blade, the scraping edge of the wiper blade is lifted from the top surface to reduce removal of accumulated ice and snow during the reverse movement.
