Abstract
This invention is a drop-lock adjustment used on automatic feeders to adjust the feed gates either up or down and includes shielded drop locks connected to control rods that pass through a channel. An adaptor plate mounted on the channel has a downwardly projecting flange spaced from the channel with an elongated slot in the plate to prevent the animals being fed from tripping the lock to cause either more or less feed to be dispensed.
