An improved cattle stanchion has a frame supporting animal restraint mechanism having a moveable restraint wand and moveable wand support bar that cooperate in moving to various operative positions. The restraint wand is hinged between its ends to the knee of the support bar. The upper end of the restraint wand cooperates with a pin moveable in an arcuate slot in the upper horizontal frame, which slot pin may also be set by hand, and the upper end of the support bar is hinged in the upper frame while the bottom end of the bar is manipulated in an oscillating, dipping movement, controlled by movement of a bus bar that may be extended to control a long row of such sections. The upper end of the support bar may also be released manually to widen the space to release a downed cow. The positions may be set for free feed, self-catch, lock-out and various permutations by movement of a control for the bus bar, or manually. |
