Abstract
An improved hog/livestock feeder uses a bump cone on a pendulum swivel as opposed to rotary motion. A support structure suspends a feed hopper directly above a feed pan. A bump cone swings with a pendulum motion within a funnel in the hopper. The lower edge of the bump cone is accessible between the open bottom of the hopper and the upper rim of the feed pan, such that when an animal nudges the bump cone, a gap between the hopper funnel and bump cone widens, and feed falls from the hopper and into the feed pan. The device enabling the bump cone to swing a pendulum motion may be a spring, a multi-axis joint, or a length of flexible material. A raised feed diverter structure may extend upwardly from the bottom of the feed pan, and the bump cone may be perforated to further distribute the feed.
