Abstract
Abstract Apparatus introduces particles of feed to fowl on a controlled basis. The apparatus includes chain link means disposed in a closed loop and movable in the direction of the loop. Means such as discs are disposed at spaced intervals in the loop for moving the particles of feed along the loop and for inhibiting the removal of the particles of feed by the fowl during such movement. Storage means receive the chain link means for holding the particles of feed and for guiding the movement of the chain link means. Such storage means may comprise a trough open at the top and dimensioned to hold the discs in a nested relationship. The discs may have an annular shape and the trough may have a semi-annular shape. The closed loop defined by the chain link means may have straight sides and rounded corners. The storage means may be closed and enlarged in section at the rounded corners. This enlargement may be defined by an oval-shaped configuration of the storage means in section. Means may control the introduction of the particles of feed to the storage means. Such means may include a hopper having an opening whose size may be controlled by a manual adjustment in the positioning of a plate. Means drive the chain link means at a relatively high speed in the direction of the loop. Means discontinue the operation of the driving means after a limited, but controlled, period of time.
