  • Patent number: 4148392
    Abstract: A closed loop conveyor for viscid material is provided with a plurality of spaced, planar conveying flights within a material conveying conduit. The flights are mounted on an endless transporting chain and are moved from one or more charge stations where material is loaded into the conduit to one or more gravity discharge stations where the material falls out of the conveyor. At the discharge station the planar conveying flights are scraped clean by a rotatable assembly. The assembly preferably comprises a circular plate mounted for rotation in a generally vertical plane adjacent to the conveying path and about a substantially horizontal axis. A number of scraper blades are mounted on the circular plate substantially uniformly, peripherally spaced from one another and extend away from one side of the plate in a generally horizontal direction toward a conveying path defined by movement of the flights.
