ABSTRACT:
A push-on type lumber stacker utilizes a pivoted conveyor for discharging the boards onto the stack and which starting from the outfeed conveyor level pivots upwardly in correspondence with the increasing height of the stack. The pivoted conveyor at its discharge end incorporates a plurality of remotely operable stick holders which hold the sticks as runners during formation of each layer and then release the sticks to serve as layer spacers. A plurality of rotary driven cams are also mounted on the discharge end of the conveyor to assist in pushing the boards onto the sticks.
