ABSTRACT:
This invention is conerned with conveyors using reciprocating flights to convey material along the length of the conveyor. The conveyor consists essentially of a bed of articulated plates, a track constraining a chain adjacent a first longitudinal edge of the bed, spaced flights attached to the chain and located to extend across the bed and means for reciprocating the chain along the track. The chain is preferably made of rigid members of substantially uniform cross-section and the flights are shaped bars having one end adapted to be pivotally attached to the chain and are reduced in their height towards their free ends with the trailing edges of each flight tapered downwardly towards their bottom surfaces and inclined towards the leading edges at their free ends which ends are chamfered. The flights include stops to limit their rotational movement over the bed and reciprocating means comprises a piston and cylinder assembly which may be connected to the chain through a flexible member passed over a system of pulleys to increase the effect of the working stroke of the assembly on the chain.
