  • Animal feeder
    Patent number: 5069164
    Abstract: An animal feeder having a rotatable feed plate. A spacer is carried by the feed plate to limit the amount of feed carried by the plate and further prevents accumulation of feed on the central portion feed plate. Limiting the amount of feed on the plate reduces the weight of feed to allow rotation of the plate by a smaller feeding animal. The spacer of this invention further reduces feed spoilage caused by static feed typically collected on the feed plate central portion. The feed plate is spaced from the feed trough by a central raised portion of the base to isolate feed carried on the plate from that in the trough. Isolating feed on the feed plate in this manner prevents the wicking of moisture from the trough into the hopper.
