ABSTRACT:
A livestock headgate is provided having certain automatic features of operation and capability for adjustment to the size of the livestock. The headgate utilizes two vertically elongated swinging frameworks which are coupled so that when one framework is swung to the forward discharge position, the second framework follows. The frameworks, in their coplanar closed positions, permit the animal's head to pass therebetween. When the animal's shoulder touches one of the frameworks, an upright member under tension is caused to rapidly close upon the neck of the animal. When the frameworks are swung to the forward discharge position, the tensioned member is automatically restored to its starting position.
