  • Patent number: 5119931
    Abstract: An auger apparatus having a first housing for receiving and holding material to be moved has a first auger disposed therein and rotatable about a first axis for moving material within the first housing. A second housing is connected to the first housing and has a second auger disposed therein and rotatable about a second axis for moving material within the second housing, the second axis being disposed at an obtuse angle with respect to the first axis. A flexible joint is attached at one end thereof to the first auger and at the other end thereof to the second auger for transmitting rotational forces from one to the other and thereby forming a flexible joint between the two augers. Helical flighting extensions are attached to each end of the flexible joint and serve as extensions to the flighting of the first and second augers so that there is essentially a continuous flighting across the flexible joint.
