Abstract
A conveyor comprises laterally spaced apart lifting/holding slats () and laterally spaced apart conveying slats () between the lifting/holding slats (). The conveying slats () are advanced in a first direction for conveying a load and are retracted in a second direction for returning them to a start position. The lifting/holding slats () have lower portions () which reciprocate and upper portions () which move up and down. Cams () operate in response to longitudinal movement of the lower slat members () to raise and lower the upper slat members (). One end of the upper slat members () is connected to a fixed structure (') by a pivoting link () which pivots to permit up and down movement of the slat member () while preventing lengthwise movement of the slat member (). The cams () are adapted to lift the upper slat member () when the lower slat member () is slid lengthwise towards the fixed ends of the upper slat members (), and to permit a downward movement of the upper slat members () in response to movement of the lower slat members () in the opposite direction.
