Abstract:
A poultry feeder comprising:a) a feeder bowl having a peripheral portion and a central portion extending upwardly from a bottom of the bowl; b) a feeder tower including an upper feed inlet, an open bottom and at least one feed opening between the upper feed inlet and the open bottom; c) at least one feeder tower protrusion extending outwardly from the feeder tower, the at least one feeder tower protrusion having a shoulder; d) a collar mounted around the feeder tower, the collar having an outer surface with a plurality of upwardly open, axial notches, bottoms of adjacent notches being at different distances between uppermost and lowermost edges of the collar, at least one collar protrusion extending from the collar toward the feeder tower, the collar being axially movable relative to the tower between a first position, wherein the at least one collar protrusion is axially displaced from the at least one feeder tower protrusion permitting free rotation of the collar relative to the feeder tower, and a second position wherein the at least one collar protrusion contacts the at least one feeder tower protrusion to prevent relative rotation between the collar and the feeder tower; and, e) a grill having a hub through which the collar passes, a rim releasably attached to the peripheral portion of the feeder bowl and a plurality of spaced apart arms extending between the hub and the rim, the hub including at least one hub protrusion releasably engaging one of the plurality of axial notches in the collar, the grill being axially movable relative to the collar between a first position wherein engagement of the at least one hub protrusion with the axial notch of the collar prevents relative rotation between the grill and the collar, and a second position wherein the at least one hub protrusion is disengaged from the axial notches of the collar, thereby permitting relative rotation of the grill relative to the collar, whereby when the collar and grill are in the first positions, the collar, the grill and the bowl may rotate as a unit relative to the feeder tower.
