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.

A shielded drop-lock adjusting means comprising:
- a support channel;
- at least one control rod means passing through at least one opening in said channel;
- a handle means pivotally mounted on one end of said control rod means and having at least one angularly disposed end;
- and an adaptor plate mounted on said channel and having at least one flange downwardly projecting therefrom in spaced relation to a side of said channel, said plate including an elongated slot running parallel to the space between the at least one adaptor flange and the channel side whereby when the at lest one angularly disposed end of said handle means is pivoted away from said support channel, such handle can be used to manipulate said control rod means and when said angularly disposed end is pivoted downwardly into engagement with said slot-like opening, such handle will be locked and cannot manipulate said control rod means.
