Abstract
A four-bar linkage mechanism for a material transfer device includes a center driving linkage, a center interconnecting linkage, right and left hand support linkages, and right and left hand main linkages. The present invention further includes the method of transferring material using a material transfer device incorporating the four-bar linkage by loading the material container into a dumper frame, positioning a pour hood over the material container, activating a hydraulic cylinder thereby rotating the material container and pour hood about 180 degrees, and releasing the contents of the material container.
