ABSTRACT:
A cattle stanchion which has posts (24) supporting a top and bottom rail (20) and (22) with spacing bars (26) in between. A number of head openings permit animal feeding through the stanchion. Each head opening includes a side bar (36) and a swing bar (46) which is supported by a pivot bar (38). The swing bar has a yoke (40) on the top aligning and retaining one end onto the top rail. A guide block (54) attached between the forked fingers (42) of the yoke slidably receives a floating locking latch (62) that interfaces with notches (72) in a drawbar positioned above the top rail. An optional lever arm (88) slides the drawbar from an open to a closed position fop each head opening and individual locking latches may be disengaged for sorting animals or if an animal is down. A rotating handle (84) permits the drawbar to be manually pivoted disengaging the locking latches from the notches providing a free feeding position for the stanchion.
