Abstract
Abstract Disclosed is an automatic horse-feeding system in which a measured amount of feed is supplied to one or more horses at frequent intervals during the feeding day of the horse. The system is characterized by a central hopper and a feed-distribution system comprising a motor-driven shaft which provides the multiple functions of agitating the feed within the hopper while driving an impeller distribution assembly which apportions the feed into one or more chutes in the predetermined measured amount. An improvement is also disclosed wherein a free-floating daisy wheel agitator is driven by the impeller to agitate the feed within the hopper. A manually-controllable damper assembly allows for simultaneously feeding different horses at different rates from the same feed hopper, while an adjustable-control circuit provides for presetting of both the interval between feedings and the amount of each feeding.
