METHOD AND APPARATUS FOR FORMING A LUMBER STACK AND PLACING STICKS BETWEEN ADJACENT COURSES IN THE STACK Abstract of the Disclosure Method and apparatus for forming a stack of elongate articles, such as lumber, by vertically laying successive lumber courses and providing sticks between adjacent courses includes a conveyor operable for transferring a course to he stacked to a first station, a course positioner disposed adjacent the conveyor openable for selectively elevating a course as a unit and shift- ing it into position above a stacking station and a stick placer disposed above the stacking station operable for selectively depositing sticks generally transversely to the lengthwise dimension of the course at laterally spaced locations thereon. Further, the positioner includes elongate members rotatably mounted on a carriage, the elongate members being operable, during rotation thereof, for selective positioning above and below the riding surface of the conveyor to thereby raise and lower a course relative to the conveyor. The carriage is re- ciprocally shiftable relative to the direction of transfer of the conveyor for selectively locating the elongate members adjacent the first station and the stacking station. The stick placer includes a driven rotary feed operable for periodically receiving sticks and directing them through a predetermined angular dis- placement and periodically releasing them onto successive courses. The rotary feed includes a plurality of rotatable wheel sets disposed above the stacking station adjacent locations where the sticks are to be deposited, and each wheel set is disposed beneath a stick-containing bin and includes a pair of opposed, spaced-apart concentrically mounted wheels operable for receiving sticks.
