Abstract
A reversible belt scraper is provided with opposite belt scraping surfaces and is adapted to be reversed by inverting. The belt scraper is formed with a pair of metal side frames, and a transversely elongated body is formed as a block of rubber defining the belt scraping surfaces on opposite sides. A pair of fiberboard backing plates are positioned to support the rubber block against forces tending to bend or deflect the rubber. The fiberboard backing plates wear at a rate faster than the wear rate of the rubber block and assure full contact between the belt and the rubber scraping body. In a further embodiment, ceramic bricks are embedded within the rubber block with wear surfaces at the rubber scraping surface. The rubber, brick and backing plates are formed in modular segments which are stacked end-to-end between the frames and retained by metal slugs which extend through the segments.
