  • Patent number: 4157005
    Abstract: An improved direct-loading crop harvester is disclosed as having an articulated elevator which is retractable into a berth in the harvester. During transportation of the harvester from field to field, the lower leg of the loading elevator is horizontally positioned within the berth upon a slidable support cradle, and the upper leg of the elevator is nestled vertically at a side of the berth. Prior to harvesting, the elevator is pulled from the side of the berth with the lower leg resting on the cradle. The elevator is then connected by pivot and hydraulic cylinder mechanisms to the berth such that the lower leg tilts upwardly at the side of the harvester and the upper leg projects outwardly from the upper end of the lower leg. During the harvesting operation, crops are fed to the elevator by a conveyor and are discharged at a selected position above an attendant trailer, preferably through a detachable decelerator mechanism.
