Feed bunk structure

Feed bunk apparatus having an upper side and a lower side the upper side of which includes means defining a trough having a base feeding surface merging at its margins with upwardly projecting walls and the under side of which includes surface portions for seating thereof to a ground surface, post means having a slip fit releasable connection with said means defining a trough and mounting in connection therewith means defining a containing enclosure, said enclosure forming a substantially continuous wall structure forming a feeding fence about the trough through which animals may feed, elements of which wall structure are displaceable to provide access for loading the trough with large bales of hay or other feed material.

Feed bunk apparatus including means defining a trough which is "H" shaped in transverse section, said "H" shape having an upper portion and a lower portion, the upper portion of said "H" providing said trough, the lower portion of said "H" providing a base for said trough and adapting said apparatus to seat directly to a ground surface and the bar portion of said "H" having a series of apertures therein adjacent its lateral extremities, and post means having portions received in said apertures, said post means being free of connection with said apparatus and positioned and maintained thereby to project upwardly therefrom and being adapted to mount a superstructure in an elevated relation to said trough.

Feed bunk apparatus having an upper side and an under side the upper side of which includes means defining a trough having a base feeding surface merging at its side margins with upwardly projecting walls and having through passages accommodating the slip fit insertion of post elements to stably mount said elements, by virtue of their insertion, in a vertically projected relation to said trough, said trough being H-shaped in cross section and said passages being incorporated in the horizontal bar portion of the H shape to position said post elements to project upwardly from said trough in closely adjacent relation to inner surface portions of the said upwardly projecting walls.

Feed bunk apparatus having an upper side and an under side the upper side of which includes means defining a trough having a base feeding surface merging at its side margins with upwardly projecting side walls and the under side of which includes surface portions for seating thereof to a ground surface, said means embodying, within the limits of the outer surfaces of said side walls, means for receiving and mounting post-like structures in a slip fit relation therewith, said means defining said trough being formed to position said post-like structures, by virtue of their slip fit, in a vertically projected relation to said trough.
