ABSTRACT:
Cattle locking apparatus in which a plurality of fixed and release stanchions are located adjacent one another to define a row of head openings for the animals. Each release stanchion is pivotally supported, and is also pivotally connected at its upper extremity to a horizontally reciprocable release rod for simultaneous movement of all of the release stanchions between open positions, in which the cattle can place their heads in the head openings, and closed positions in which the cattle are locked in the apparatus. Decouplers are operative upon movement of the release stanchions to their open positions to permit the release rod to be moved back to its previous position independently of the now open release stanchions. The release stanchions each include an actuator located below the release stanchion upper portion, and also located in the head opening in the open position of the release stanchion. In this position the actuator is engageable by the neck of an animal with its head in the head opening and the release stanchion is pivotable to its closed position by the animal as it dips its head in the opening to feed. In their closed positions the release stanchions re-engage the master rod and thereby automatically lock the cattle in place. Means are provided to disable the self-locking mechanisms, when desired, so that the cattle cannot lock themselves in the apparatus until the release rod is moved by an operator.
