Abstract
A head gate mounted on a cattle squeeze chute through a series of spring-type shock absorbers allows the head gate to move a limited distance in the longitudinal direction from the squeeze chute when impacted by an animal as the pivoting doors on the head gate restrain the animal's forward movement through the chute.
Claims5
An improved head gate on a cattle-squeeze chute, the chute having a longitudinally extending box shaped structure with entry and exit ends on the structure, the head gate being attached to the exit end of the structure;
- the head gate comprising:
- a rigid frame having horizontal top and bottom members;
- a pair of doors pivotally mounted to the bottom member of said frame, the top member of the frame including a slot means which receives the upper ends of said doors, guiding their opening and closing movement within the plane of said head gate frame;
- actuating means attached to said doors for opening and closing the door around the head of an animal;
- biasing means attaching the head gate frame to the squeeze chute structure permitting the head gate frame to move a limited distance in the longitudinal direction from the chute structure whereby the impact and injury of an animal moving longitudinally through the chute with the head gate doors is diminished.
