Abstract
A headlock stanchion panel has latch and release mechanism situated along the top rail for each release stanchion, and is adapted for individual or gang release. There are a pair of release latches each having a tongue that engages a latch member that extends from the end of the release latch. The latch members are mounted on the outsides of respective latch supports, and pivot on bushings. Finger lift members on the pivot latches facilitate individual release. Ear guards are provided to block access from the head side of the top rail to the pivot latches to prevent self-release of the cows.
Claims15
A multiple stanchion headlock panel comprising:
- a frame that includes a horizontal top rail, a plurality of vertical braces extending to the top and base rail at predetermined intervals, and a plurality of fixed stanchions extending vertically between the top and base rails at a predetermined spacing from the associated ones of said vertical braces to define cow positions therebetween;
- and
- each said cow position including:
- a support member affixed onto the respective vertical brace;
- a vertical release stanchion pivotally supported on said support member substantially midway between said brace and said fixed stanchion and having a portion thereof projecting above said top rail;
- a latch and release mechanism, for releasably holding the vertical release stanchion in a vertical position;
- and
- an ear guard member positioned at one lateral side of the latch and release mechanism above said top rail to block access to said pivot latch from said one lateral side, to prevent a cow from self-releasing from the cow position.

A multiple stanchion headlock panel comprising:
- a frame formed of a horizontal base rail and a horizontal top rail, a plurality of vertical braces extending between the top and base rails at predetermined intervals, and a plurality of fixed stanchions extending vertically between the top and base rails at a predetermined spacing from the associated ones of said vertical braces to define cow positions therebetween;
- and
- each said cow position including:
- a support member affixed onto the respective vertical brace;
- a vertical release stanchion pivotally supported on said support member substantially midway between said brace and said fixed stanchion and having a latch member projecting from an upper end thereof to project above said top rail;
- and
- a latch and release mechanism, for releasably holding the vertical release stanchion in a vertical position, the latch and release mechanism including at least one pivot latch that is pivotally supported on a pivot support member over said top rail, and having a tongue that is normally in a lowered position to engage the latch member of said release stanchion, and can be lifted to a raised position wherein said tongue is out of engagement with the latch member to permit the release stanchion to pivot to a tilted position;
- and
- an ear guard member positioned at one lateral side of the at least one pivot latch above said top rail to block access to said pivot latch from said one lateral side.

- and
- each said cow position including:
- a support member affixed onto the respective vertical brace;
- a vertical release stanchion pivotally supported on said support member substantially midway between said brace and said fixed stanchion and having a latch member projecting from an upper end thereof to project above said top rail;
- and
- a latch and release mechanism, for releasably holding the vertical release stanchion in a vertical position, the latch and release mechanism including at least one pivot latch that is pivotally supported on a pivot support member over said top rail, and having a tongue that is normally in a lowered position to engage the latch member of said release stanchion, and can be lifted to a raised position wherein said tongue is out of engagement with the latch member to permit the release stanchion to pivot to a tilted position;
- and
- said pivot latch having a pivot portion that has lateral sides that extend over outer sides of the associated pivot support member;
- and a pivot member is formed of first and second bushings, the lateral sides of the pivot latch having openings through which an associated on of said bushings passes, such that the pivot member is journaled on said bushings;
- and a fastener member passing through said bushings to hold the bushings onto the pivot support member.
