SWEEPER DUST SEAL ABSTRACT OF THE DISCLOSURE This specification discloses a roller-type dust seal for use in a sweeper of a type including a dust receiver or bin having an open end spaced from a brush and from the surface being swept. A generally U-shaped axle having an elongated base is positioned transversely of the brush and supported adjacent the inlet opening of the dust receiver. The legs of the axle are secured to the bin so that the base portion is generally free floating. A plurality of generally hollow, cylindrically shaped, abutting roller segments are received on the axle. The roller segments have a relatively hard inner peripheral surface and a relatively soft outer peripheral surface. -1-
