ABSTRACT:
An automatic headgate for animals has a rigid, vertically standing frame provided with an opening permitting an animal to pass through the frame. A gate assembly forming a traffic funnel for guiding animals into position for retention by the headgate is mounted on the frame for selective movement between an open position and a closed position in which the gate assembly forms a stanchion restraining an animal from movement. Connected to the gate assembly is a force-applying arrangement disposed for biasing the gate assembly toward its closed position, while a trigger mechanism is connected to the gate assembly for releasably retaining the gate assembly in its open position and releasing the gate assembly to its closed position when pressure lateral of the vertical is applied to the gate assembly from within the opening of the frame as by an animal attempting to pass through the headgate.
