ABSTRACT:
This improved cattle stanchion discloses an essentially coplanar and rectangular frame for automatically locking and manually releasing the heads of cattle. The frame unit consists of three vertical bars and two essentially horizontal bars, the top of which being slightly arched upwardly to form an apex over the center of the frame while the bottom bar is slightly arched downwardly to form a nadir under the center of the frame. These arches define an arc of travel for the central pivotally mounted vertical bar with an annular ring extension around the top arch of the frame. The annular ring cooperates with a locking mechanism consisting of pairs of elliptical latching sleeves mounted linearly apart and above the frame unit on a horizontal bar which may be operated by an attendant to either lock or unlock the stanchion.
