Abstract
A method and apparatus are disclosed for forming alternating layers of coarse feed elements and fine feed elements when loading a livestock feed storage structure. The apparatus includes a center fill tube and a movable distributor supported from the center fill tube. The distributor includes a pan and a drive to rotate the pan about a central axis. When positioned in alignment with the center fill tube, feed is distributor filled into the storage structure. When positioned out of alignment with the center fill tube, feed is center filled into the storage structure. Alternating between distributor fill and center fill creates the layering of coarse and fine elements.

- and
- a pan secured to said second tube at its outlet end and positioned at an angle with respect to the central axis of said second tube so that when said distributor means is in the first operative position, feed will be directed by the pan radially outwardly from the central axis of said second tube, said feed distributor means is dimensioned to fit within the access aperture of the feed storage structure, said means for rotatably supporting said second tube comprises:
- an annular mounting ring secured to said first tube adjacent its outlet end;
- a channel-shaped ring secured to said second tube adjacent its inlet end;
- and
- a bearing secured to said mounting ring and riding within said channel-shaped ring so that said second tube is rotatably supported from said first tube, and wherein said drive means further comprises:
- means interconnecting said output shaft of said drive motor to said second tube for rotating said second tube as said output shaft rotates, and wherein said apparatus further includes:
- control means operatively connected to said drive motor so that said drive motor may be actuated only when said distributor means is in said first position.

- a drive motor mounted on said mounting ring, said motor having an output shaft;
- and
- means interconnecting said output shaft to said second tube for rotating said second tube as said output shaft rotates, wherein said means interconnecting said output shaft to said second tube comprises:
- an elongated roller chain secured to and extending around the entire outer periphery of said second tube;
- a gear engaging said roller chain, said gear being nonrotatably secured to said output shaft;
- positioning means connected to said distributor means for selectively moving said distributor means between said first operative position at which the central axis of said center fill tube, said first tube and said second tube are essentially aligned and said second inoperative position at which said distributor means is moved away from said center fill tube discharge end so that feed will pass directly into the feed storage structure from said center fill tube;
- and
- control means operatively connected to said drive motor so that said drive motor may be actuated only when said distributor means is in said first position.
