A wheel supported sweeping machine includes a hopper which is movable between operating and non-operating positions and a conveyor which is adjacent the hopper and is similarly movable between a lower operating position and a raised non-operating position. There is a cylindrical brush mounted on the frame which directs debris into the conveyor, with the conveyor raising the debris for deposit into an opening in the upper end of the hopper, which is aligned with a similar opening in the conveyor. At times, debris may fall into the space between the conveyor enclosure and hopper. A debris collecting ramp is located beneath the hopper and extends upwardly and rearwardly toward the hopper from the conveyor enclosure. There is a seal between the ramp and conveyor enclosure which prevents debris from falling downwardly until the conveyor enclosure has been raised, at which time, the debris will be deposited by the ramp through a lower opening in the conveyor enclosure to an area in the front of the brush.

[What is claimed is:] [1.]a conveyor mounted on the frame in a generally upright position and movable between a lower operating position and a raised non-operating position, said conveyor being located to collect debris swept by the brush and to raise such debris for deposit in the hopper through an opening in the hopper generally in alignment with an upper portion of the conveyor, an enclosure for said conveyor and having an upper opening generally in alignment with the hopper opening, a seal extending at least partially about the aligned hopper and conveyor openings to prevent debris moved by the conveyor to the hopper from falling into a space between the hopper and conveyor enclosure,and a ramp, fixed on the frame and extending from adjacent the conveyor enclosure upwardly and rearwardly toward and beneath the hopper and generally adjacent the bottom of the space between the hopper and conveyor enclosure, a seal between said ramp and conveyor enclosure, a lower opening in the conveyor enclosure, said lower opening being located beneath the ramp seal, said seal preventing debris on the ramp from reaching the lower conveyor opening when the conveyor and hopper are in the lower operating position, said ramp being aligned with the lower conveyor opening when the conveyor and hopper are in a raised non-operating position whereby any debris in the space between the hopper and conveyor enclosure will fall from the ramp into the conveyor enclosure.
