Abstract
Abstract A chain driven conveyor apparatus. A drive end and a tail end, sprocket wheels at the drive end and wheels at the tail end having peripheries of greater width than the chains and of uniform circumferential and transverse continuity over which the chains travel. A plurality of flights pivotally connected at each end to a chain, and means at the tail end of the conveyor limiting transverse movement of each flight as it reverses its direction of travel at the tail end of the conveyor.

A conveyor apparatus including, in combination, a conveyor bed on which material may be moved along a substantial horizontal plane a drive end and a tail end, a pair of spaced apart chain drive sprocket wheels at the drive end of the conveyor and a pair of spaced apart wheels at the tail end and thereof, a pair of drive chains, one extending between and over a chain drive wheel of the pair of chain drive wheels and a wheel of the pair of wheels, and the other chain extending over the other chain drive wheel and the other wheel, the sprockets of each chain drive wheel extending into the interstices of each chain whereby each chain is driven by the chain drive sprocket wheels, and the wheels at the tail end of the conveyor having peripheries of uniform circumferential and transverse continuity and the peripheries of the wheels at the tail end of the conveyor being of greater width than the width of the chain, and a plurality of generally rectangular elongated flights are provided having longitudinal and transverse edges and being connected at each transverse edge to a chain and extending therebetween, the flights being spaced apart longitudinally with respect to the chains and the flights being so connected to the cHains providing substantially one-half of each flight extending in a plane below a projected horizontal plane between the chains, and each of said wheels at the tail end of the conveyor being provided with a portion in the same horizontal plane as that in which said onehalf of each flight is positioned, each transverse edge of each of said one-half of each flight being normally spaced from said portions, one transverse edge of a flight being engageable with one of said portions upon lateral movement of the flight in one direction, and the other transverse edge of the flight being engageable with the other of said portions upon lateral movement of the flight in the opposite direction, and the greater width of the peripheries of the wheels at the tail end of the conveyor being substantially equal to the distance each transverse edge of a flight is normally spaced from each portion of each wheel at the tail end of the conveyor.
