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. A mechanically linkage mechanism moves the gates between their first and second positions, such that the gate disposed diagonally opposite one another rotate in the same direction and the gates disposed adjacent one another rotate in opposite directions.
