Abstract
Apparatus for attaching conveyor chains and flights utilized in shuttle cars are disclosed. The flight attachment design includes an attachment link with male members extending from the roller links to which the flights are to be attached. The roller links have slots which allow the engagement of each of the roller links by the drive sprockets. A specially designed flight has female ends which are positioned around the male extensions of the roller links. Retaining pins inserted in cooperating holes secure each of the flights to the male members of the roller links. The roller links of each conveyor chain are connected by side plates and pins positioned on each side of the roller link such that a slot remains between the roller links which may be engaged by the drive sprockets.
