Chain and flight conveyor

Abstract

A chain and flight conveyor adapted to be driven by a toothed sprocket comprising a pair of spaced apart, parallel driving chains, each of the driving chains comprising roller links having at least one end surface which may be drivingly engaged by the teeth of the sprocket. The roller links also have internal apertures defining drive surfaces which may be drivingly engaged by the teeth of the sprocket. The driving chains further include connecting links coupled to and interconnecting the roller links; and pins pivotally connecting the connecting links to the roller links. A predetermined corresponding number of the pins on each of the chains comprises extended flight attachment pins having pin extensions facing the opposite chain. A plurality of conveying flights are connected between the corresponding number of the pin extensions, the flights comprising a bar member having two opposite ends, four sides and a bottom surface. The bar member bottom surface has at least one indentation provided on the bar member ends, each of the indentations being adapted to receive its respective pin extensions. The flight further includes a bolt extending through the flight sides forming the indentation, the bolt being secured to the flight so that the pin extensions are held in the indentations.
