ABSTRACT:
A conveyor for sorting logs is pivotably mounted on a support structure and is rotatable about an axis parallel to the direction of log transport. The apparatus includes double chamber pneumatic cylinders which may be selectively actuated to pivot the conveyor to dump logs therefrom to either side of the support structure. Limit switches on the conveyor are operatively connected in a control circuit arrangement to prevent the piston within the cylinders from reaching its limit of travel, thereby providing an air cushioned, shock absorber effect. The conveyor drive mechanism acts as a counterweight to return the conveyor to a level orientation.
