Abstract
Abstract The packaging machine is provided with a dumper shaft which includes material receiving chambers which can be adjusted in size to receive and measure varying amounts of material. Each material receiving means is made up of a pair of coaxial discs and radiating plates between the discs, the discs being held in place by locking collars. Outlet nozzles from the hopper above the dumper shaft are disposed to empty into a respective chamber while being disposed within the plane of the chamber. As the dumper shaft is rotated, the hopper and the outlets are raised to permit rotation. The upper edge of each plate has a lip or ledge directed in the direction of rotation of the dumper shaft to retain the material during rotation.
