  • Patent number: 5289798
    Abstract: An improved livestock handling apparatus and method include a frame mounted on wheels having a plurality of stanchions arranged in side-by-side relationship along sides thereof such that livestock can place their heads through the stanchions in a first position, and reach feed placed in troughs and bales placed on rails spaced interiorally to the apparatus. Locking mechanisms, each comprising a pivotally mounted latch abutting an upper end of a pivotable sidebar of each of the stanchions, automatically lock the sidebar in a second position such that an animal cannot pass its head into, or remove its head from, one of the stanchion. A deactivator, including an axially rotatable rod having nubs spaced therealong, interacts with the latches to deactivate the locking mechanisms such that the livestock can pass their head through and remove their head from the stanchions.
