Abstract
A feeding device placed between an infeed conveyor and two longitudinal lumber conveyors for directing pieces of lumber, e.g., logs, fed thereto to one or the other of the two longitudinal conveyors which carry the logs for further processing. The first unit in the feeding device arrangement is a singlepiece feed conveyor, with a photo cell device, which receives a log from the infeed conveyor. The next station is a vertically swingable flap disposed over a gap which can be bridged by the flap. Under the gap is a stepwise drivable winged wheel or set of wheels which is offset adjacent and above one of the longitudinal conveyors which also has an associated photo cell device. Next in the device and located adjacent the base of the flap is a stepwise drivable transverse conveyor which receives logs passing over the flap and has its discharge adjacent and above the second longitudinal conveyor which also has an associated photo cell device. The swingable flap is operated and controlled by automatic equipment, in which the photo cell devices associated with the single piece feed conveyor and the longitudinal conveyors control the position of the flap depending on which longitudinal con…
