Flexible joint for augers
First Claim
1. Auger apparatus comprising:
- a first rigid housing means for receiving and holding granular material;
a first auger means disposed in said first rigid housing and rotatable about a first axis for moving granular material within said first housing;
a second rigid housing means immovably connected to said first rigid housing for receiving and holding granular material;
a second auger means disposed in said second housing and rotatable about a second axis for moving granular material within said second housing, said second axis being disposed at an obtuse angle with respect to aid first axis;
a flexible joint means at the vertex of the rigid housing means, and comprising an elongated metal cable attached at one end to a first cap connected to said first auger means and at the other end thereof to a second cap connected to said second auger means for transmitting rotational forces from one of said first auger means to the other of said second auger means;
a first at least partially helical extension flighting disposed in said first rigid housing means and attached to said first auger means for rotating therewith and extending both radially outwardly and projecting over at least a substantial portion of the elongated metal cable of the flexible joint means thereby moving granular material over said flexible joint means during rotation thereof; and
a second at least partially helical extension flighting disposed in said second rigid housing means and attached to said second auger means for rotating therewith and extending both radially outwardly and projecting over at least a substantial portion of the elongated metal cable of the flexible joint means and toward said first helical extension flighting thereby moving granular material over said flexible joint means during rotation thereof.

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.
