ABSTRACT:
A self-locking cattle head gate assembly is provided for restraining the head of an animal in a relatively immobilized position while medication or other treatment is administered thereto. A pivotally mounted chute gate is positioned at the end of a stall or animal chute so as to selectively effect lockable closure thereof. An animal shoulder-engaging head gate is pivotally mounted within the chute gate so as to be selectively openable therefrom. As the animal moves toward the closed chute gates, the head thereof extends through the closed chute gate and the shoulder thereof engages the open head gate so as to move the head gate to its closed locked position within the plane of the chute gate. As the head gate moves into its closed position within the chute gate, the upper end thereof engages and lifts a downwardly inclined lock latch plate pivotally mounted on and extending outwardly from the upper peripheral edge of the chute gate. When the head gate reaches its fully closed position within the plane established by the outer edges of the chute gate, the lock latch plate disengages from the head gate and drops back into its normal lock position behind the upper edge of the head gate so as to lock it into its closed position within the plane of the chute gate. In its closed position, the outer free vertical edge of the head gate cooperates with the inside surface of the vertical edge of the chute gate proximate thereto so as to restrain the neck of the animal therebetween. Thus restrained, the head of the animal extends outwardly beyond the head gate assembly in a relatively immobilized position so as to greatly facilitate the treatment of the animal as desired.
