Abstract
A conveyor system for delivering feed to a plurality of animal cages arranged in rows said system comprises an endless conduit extending along a conduit run past at least one of the rows of cages and through a feed trough disposed adjacent the faces of the row of cages. An elongate, continuous, endless material moving element extends through the endless conduit run and is longitudinally movable therethrough, and a driver element advances the endless material moving element along and through the conduit run. The material moving element comprises an elongate helical member defining a longitudinal helix axis and bendable about this axis for following the endless conduit run. Cooperating structure on the driver element and on the helical member rotates the helical member about the helix axis thereof while simultaneously axially advancing the helical member along and through the conduit run.
