  • Stacking of materials
    Patent number: 4339220
    Abstract: A stacking assemblage fed from a conveyor which transports materials to a staging area. The materials are formed into a tier on a movable platen of the assemblage in accordance with a prescribed pattern. The platen can be raised or lowered to a desired level and then shifted to deposit each tier on an outboard conveyor until a desired multi-tier stack is formed.

  • Method and apparatus for transporting materials
    Patent number: 4008890
    Abstract: Method and apparatus employing serially positioned conveyors which are reorientable relative to one another in order to position an incoming stack of materials for transport and automatic stacking at an output position. Two of the conveyors are tiltable to upset the stack and provide initial shingling. Further shingling is achieved using an inclinable shingling conveyor in conjunction with a stripper unit.

  • Method for transporting and reorienting a stack of materials
    Patent number: 3982750
    Abstract: Method employing serially positioned conveyors which are reorientable relative to one another at a common position in order to position an incoming stack of materials for transport and automatic stacking at an output position. The speeds of the conveyors are variable and reversible, and the motive power for both operating the conveyors and reorienting them and associated elements is supplied hydraulically. Transport to the output position is over an inclinable shingling conveyor and a retractable output conveyor.
