Abstract: The apparatus is a remote controlled gate assembly. The rotation is accomplished by rotating a plate with an attached yoke to capture the lower rail of the gate. The yoke arrangement permits the gate to be manually operated by lifting it out of the yoke. The plate is itself rotated by a drive shaft passing through a hole in a device attached to the end of the gate. Multiple gates can be driven by a single cable, which moves around pulleys atop the drive shafts. The gate or the drive cable is driven by a remote controlled reversible motor, permitting the operator to open or close the gates without actual contact.

Abstract: A freestall barn for dairy cattle arranged with a plurality of freestall resting areas with resting stalls, and a feed alley; has a feed drive through for a feed delivery vehicle, with feed alleys of the freestall resting areas adjacent and parallel to the feed drive-through. A cow lane crosses the feed drive through forming an intersection with it. The cow lane connects the freestall resting areas, and permits cows to proceed to and from a milking station. A four-way drive-through gate assembly has four horizontal gates disposed to pivot or swing on vertical axes at respective corners of the intersection. In a first position the gates block the drive-through but permit passage of cows along the cow lane. In a second position the gates block the cow lane but permit the feed delivery vehicle to pass through along the drive-through.
