Abstract: A double central chain belt assembly for a chain scraper conveyor has scraper members arranged at spacings relative to each other. Each scraper member comprises a central portion and two outside portions of the same configuration. Each adjacent pair of scraper members are connected together by a pair of chain portions which are arranged at respective sides of the center line of the assembly. Each end of each chain portion terminates in an end link which serves as a connecting link. The central portion and the outside portions of each scraper member are releasably connected together. Each central portion has engagement surfaces disposed in opposite relationship in the longitudinal direction of the assembly for the engagement of the teeth of a pin gear. On its outside at both sides, each central portion has flanks with oppositely disposed openings for receiving the end links of the chain portions therein. Each flank is arranged to receive, and to be secured, an outside portion.
