Abstract:
An assembly for supporting a reversible belt scraper blade on the support arms of a belt scraper and providing for renewal of the belt scraping surface by rotating the scraper while supporting the blade on the belt scraper arms, in which the blade is formed with non-circular axially extending mounting studs on the ends thereof by which the blade is mounted and secured against rotation on the belt scraper arms, comprising:an elongated base piece having a plate-like body and an inner end adapted to be received and mounted on an arm of the belt scraper and having an outer end, said outer end having therein a generally circular opening therethrough adapted to receive the support stud of a belt scraper blade therethrough permitting rotation of the blade with respect to said base piece, said base piece intermediate said ends having a pair of laterally spaced upstanding bosses defining with said body, generally a U-shaped space, said bosses being apertured to receive a linch pin extending transversely of said space,a retainer plate having an inner end and a remote end, said retainer plate inner end being dimensional to fit within said U-shaped space between said bosses on base piece bosses, said retainer plate remote end having formed therein a shaped opening corresponding to the shape of a blade mounting stud and in axis alignment with said opening in said base piece, such that when such stud is extending through the said openings in said retainer plate and base piece, that rotational torques applied to the blade are transmitted by the blade stud to said retainer plate,said retainer plate, on an outer surface thereof in said U-shaped space, having an inclined wall positioned as a bounding surface against such retainer pin, preventing withdraw of said retainer plate from said base piece when a linch pin is inserted in said boss apertures.
