Universal adjustable feeder

A universal feeder, comprising:

• a container having at least one side wall with an inner-facing side defining a storage space, the at least one side wall having an upper end, a lower end, a feed access side, and a non-feed side;
• a feeder tray having a sloped portion and a flat portion, the sloped portion comprising at least one triangular sloped face with an uppermost apex positioned above the flat portion and the at least one triangular sloped face having a lowermost end positioned within the storage space when the lower end rests on the flat portion of the feeder tray adjacent an intersection of the flat portion with the sloped portion;
• a telescoping support leg having a bottom end connected to the feeder tray and a container end attached to the at least one side wall;
• a removable lid sized and shaped to cover the upper end of the at least one side wall;
• an inner wall inside the storage space, the inner wall having a bottom end attached to the sloped portion and the uppermost apex, such that the bottom end approximates an inverted V-shape, and an upper end in slideable relationship with the inner-facing side of the container on the non-feed side;
• a wall adjuster having a top end and a bottom end, and a moving tube in telescoping, rotatable relationship with a fixed tube via mating threads;
• a horizontal element attached to both the moving tube of the wall adjuster and to the container end of the telescoping support leg such that the horizontal element is perpendicular to the wall adjuster;
• wherein the bottom end of the wall adjuster is attached to the uppermost apex and a bottom end of the sloped portion is immediately adjacent the flat portion of the feeder tray, such that the bottom end of the sloped portion meets the flat portion of the feeder tray at an angle facing the feed access side of the at least one side wall;
• wherein the top end of the wall adjuster is further comprised of a handle end adapted to receive either a crank handle or a motor with a power supply and controller for actuating the motor, the crank handle or the motor adapted to rotate the moving tube of the wall adjuster clockwise or counterclockwise;
• and
• a feed dispensing slot between the lower end of the at least one side wall of the container and the flat portion of the feeder tray;
• whereby the feed dispensing slot is opened when the at least one side wall of the container is lifted above the feeder tray and closed when the at least one side wall of the container rests on the feeder tray.
