ABSTRACT:
An apparatus dislodges material from a rotating brush having a brush axis and elongated bristles extending outwardly therefrom. The apparatus includes an obstruction device for temporarily obstructing free rotation of the bristles about the brush axis such that the bristles are placed in spring tension as the brush rotates. The obstruction device releases the bristles when sufficient spring tension exists therein.
