Abstract
Abstract Auger apparatus includes a drive portion, a connector portion and a flight portion. The drive portion includes an elongated rigid shaft member including a longitudinal axis disposed along the path of material being advanced by the auger apparatus. The connector portion includes a continuous stub section affixed to and extending outwardly from the periphery of the shaft member, the stub section being spirally disposed around the shaft member along the length thereof. The stub section includes a surface extending outwardly from the shaft member and substantially perpendicular thereto. The flight portion includes a plurality of radially cut elongated disc members, each of the disc members having an internal opening substantially equal in diameter to the outside diameter of the shaft member. An internal section of each disc member surrounding the internal opening thereof is in full contact with and affixed to the perpendicular surface of the stub section. The disc members are arranged sequentially in contact with the perpendicular surface of the continuous stub section along substantially the entire length thereof with radially cut edges of adjacent disc members butting against each other along planes oriented diagonally to a major surface of the disc members. The disc members are disposed on the side of the stub section adjacent the material being advanced by the auger apparatus.
