Abstract
A self-propelled apparatus for dislodging and collecting materials from a surface and having particular use in removing roofing from a roof deck. The apparatus includes a small tractor-like vehicle having a frame and a blade extends forwardly of the frame and is adapted to move along the surface. A brush is mounted adjacent the forward edge of the blade and is adapted to sweep the dislodged material up the blade to an endless conveyor which is mounted on the frame. The brush includes a series of rigid fingers which are located within the bristles and act to move heavy materials up the inclined blade to the conveyor.

A self-propelled apparatus for dislodging material from the surface and conveying the material for collection, comprising a self propelled vehicle including a frame, a scraping member extending transversely of the vehicle and mounted forwardly of the frame, said scraping member comprising a blade having a relatively sharp edge disposed to engage a surface as the vehicle is propelled to dislodge material from the surface, conveying means mounted on the frame and located to the rear of the scraping member in position to receive dislodged material from the scraping member and convey the dislodged material rearwardly to a position for collection, a brush having a plurality of flexible bristles and mounted adjacent to the forward edge of the scraping member, and means for rotating the brush whereby the brush will sweep dislodged material rearwardly across the scraping member to the conveying means.
A self-propelled apparatus for dislodging material from a surface and conveying the dislodged material for collection, comprising a self propelled vehicle including a frame, a blade extending forwardly of the frame and disposed to scrape material from said surface, an endless conveyor mounted on the frame and located to the rear of the blade in position to receive dislodged material from the blade and convey the dislodged material rearwardly to a position for collection, a brush located adjacent the forward end of the blade and having a series of bristles disposed to rotate in contact with said blade and sweep dislodged materials across the blade toward the conveyor, means for rotating the brush, said brush comprising a shaft and a plurality of generally flexible bristles extending outwardly from said shaft, said brush also including a plurality of generally rigid members extending outwardly from said shaft and disposed among said bristles, and mounting means connected to the brush for positioning the outer extremity of the rigid member with respect to said blade.
