Abstract: An animal feeder has a feed hopper with side walls, end walls, a bottom assembly, and an open top. Moveable gates extend below the lower edge of the side walls and are slidably mounted upon the side walls. The bottom assembly includes a feed trough under the gate in communication with the feed hopper. An adjustment mechanism allows vertical adjustment of the gate relative to the feed trough and includes an upwardly extending rod connected at its lower end to the gate and at its upper end to one end of a crank lever. The crank lever is rotatable about a pivot provided in a bracket extending perpendicularly to the end walls of the feed hopper. A pair of handles extends through a pair of slots provided in an arcuate panel attached to the bracket. Rotational movement of the handle and crank lever cause vertical adjustment of the gate.

Abstract: A counterweighted, crowd gate includes parallel overhead tracks extending from end to end of a holding area for cows. A wheeled carriage extends between and rides on the tracks. An electric motor drives the carriage between the entrance and exit of the holding area. A counterweighted gate pivotally attached to the carriage extends perpendicularly to the floor of the holding area. A latch on the carriage holds the gate in essentially a vertical orientation. An operator trips the latch and the counterweight pivots the gate to a substantially horizontal position, so the gate passes over animals in the holding area upon return to the entrance. The gate is pivotally mounted to the carriage by bushings that electrically insulate the gate from the carriage to prevent harm to animals or individuals that come in contact with the gate. A control panel allows operation of the crowd gate from a remote location.

Abstract: A wet/dry feeding device for the watering of live stock, primarily smaller animals such as baby pigs comprising; vacuum valve with diaphragm, water holding reservoirs, water leveling tube, and double walled feeding tube. The water level is automatically maintained within the holding pans by an adjustable feeding tube which is placed into the water at a perpendicular angle to the water surface. At the top of the feeding tube a vacuum valve with diaphragm is located to allow water into the holding reservoirs until the water level enters the feeding tube sleeve activating the vacuum valve, closing the flow of water.
