ABSTRACT:
A self-indexing exit gate for a side-by-side milking parlor has a yoke member that is cantilevered on a sleeve that is journaled on an overhead rotary pivot bar. A latch member affords a limited amount of play between the sleeve member and the pivot bar. A pneumatic cylinder rotates the pivot bar between the first and second positions, which correspond to lowered and raised positions of the exit gate yoke member. The yoke member has a center of gravity positioned somewhat distally of the rotary shaft, which provides a small amount of play, that is, about six inches, at the point of contact with the shoulders of the cow. The latch member permits individual release of a cow from her stall without affecting the exit gates of the other stalls in the dairy parlor.
