  • Patent number: 5333572
    Abstract: A rotary animal feeder that slowly, periodically discharges feed in response to temperature changes. Preferably the feeder is hung from a tree over an animal trail. A cylindrical pail stores a quantity of feed to be dispensed. Feed is drawn downwardly by gravity to an activator assembly comprising a discharge tube in fluid flow communication with the pail interior. A plurality of radially spaced apart discharge orifices are formed in the tube. A convex floor adjustably, coaxially secured within the tube mounts a rotary impeller proximate the discharge orifices. A bimetallic spring beneath the floor torsionally drives the impeller in response to temperature changes. Feed contacting the convex floor is slowly deflected outwardly towards the discharge orifices both by the shape of the convex floor plate and impeller contact. As the temperature changes the impeller slowly rotates, and feed is gently urged toward and through these orifices.
