    Abstract: A conveyor chain assembly with upper and lower chain runs separated by a deck has scraper bars each attached to the outer two links of a three link chain run. The outer links can rotate relative to the center link to allow the chain to negotiate a sprocket. Each scraper bar is formed with two frame members pinned together to form closed slots which house the outer links. The attachment may be duplicated to connect a bar to two parallel chains if required.
