Abstract
A conveyor chain includes a first link, a second link, and a coupler link. The first link includes a first sprocket-engaging portion and a second sprocket-engaging portion, each protruding laterally away from one another. The second link includes a first sprocket-engaging portion and a second sprocket-engaging portion, each protruding laterally away from one another. The coupler link couples the first link to the second link, and the coupler link is positioned laterally between the first sprocket-engaging portion and the second sprocket-engaging portion of each link. The coupler link includes a first joint pivotably coupled to the first link and a second joint pivotably coupled to the second link. The first joint permits pivoting movement of the first link about a plurality of axes, and the second joint permits pivoting movement of the second link about a plurality of axes.
