Abstract
A flight attachment is provided for a drive chain comprised of a plurality of overlapping links pivotally connected by pins so that stress loads transmitted through the chain by flight are transferred through the chain pivot pins and not through the chain side bars. The flight attachment comprises a pair of flight brackets, one located on each side of a link of the chain and connected to the chain in cantilever fashion by elongate, laterally extending pivot pins. The flight brackets are constructed and arranged to accept a collector flight securely mounted thereon.
