Abstract
Abstract Six panels are hinged together at adjacent ends to form a haystack feeder. The hinging allows the feeder to collapse inwardly into two triangular configurations as the cattle eat away the haystack.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
153 words
A haystack feeder comprising six panels hingedly connected to provide an enclosure having two end panels and four side panels; each panel including first and second end posts, upper and lower members connecting said end posts and therewith providing a frame, and means carried by the frame and defining openings for receiving the heads of feeding animals; each first end post having a cantilevered end; and hinge means interconnecting each first end post with the second end post of the adjacent panel and arranged to allow each pair of side panels to swing inwardly so that the enclosure collapses generally into two triangular configurations, and the hinge means including a collar slidably mounted on the second end post and arranged to selectively receive the cantilevered end of the first end post of the adjacent panel in a hinged position, and means for releasably holding the cantilevered end and collar in said hinged position.
Claim 2
Dependent Claim
153 words
A haystack feeder comprising six panels hingedly connected to provide an enclosure having two end panels and four side panels; each panel including first and second end posts, upper and lower members connecting said end posts and therewith providing a frame, and means carried by the frame and defining openings for receiving the heads of feeding animals; each first end post having a cantilevered end; and hinge means interconnecting each first end post with the second end post of the adjacent panel and arranged to allow each pair of side panels to swing inwardly so that the enclosure collapses generally into two triangular configurations, and the hinge means including a collar slidably mounted on the second end post and arranged to selectively receive the cantilevered end of the first end post of the adjacent panel in a hinged position, and means for releasably holding the cantilevered end and collar in said hinged position.
Claim 3
Dependent Claim
38 words
A haystack feeder as set forth in claim 1 wherein each first end post has cantilevered ends at both top and bottom; and there is a collar at both the top and bottom of each second end post.
Claim 4
Dependent Claim
28 words
A haystack feeder as set forth in claim 2 wherein each collar has a cross-section in the shape of two contiguous rings, each ring circumjacent one end post.
Claim 5
Dependent Claim
56 words
A haystack feeder as set forth in claim 3 wherein at least the second end post is square in cross-section, the means for releasably holding the cantilevered end and collar in said hinged position is in the form of a fastener releasably mounted on the second end post and overlying the collar at the top thereof.
Claim 6
Dependent Claim
123 words
A haystack former and feeder comprising: a plurality of panels connected to form an enclosure; each panel including first and second end posts, means interconnecting the end posts to provide structural rigidity to the panel and defining openings for the passage of heads of feeding animals, the first end post having a cantilevered end at the top, a collar slidably mounted on the second end post between a raised position and a position circumjacent the cantilevered end of the first end post of an adjacent panel to form a hinge connection therewith, locking means for holding the collar in said circumjacent position, and interfitting means at the bottom of the first and second end posts to form a hinge connection between adjacent panels.
Claim 7
Dependent Claim
123 words
A haystack former and feeder comprising: a plurality of panels connected to form an enclosure; each panel including first and second end posts, means interconnecting the end posts to provide structural rigidity to the panel and defining openings for the passage of heads of feeding animals, the first end post having a cantilevered end at the top, a collar slidably mounted on the second end post between a raised position and a position circumjacent the cantilevered end of the first end post of an adjacent panel to form a hinge connection therewith, locking means for holding the collar in said circumjacent position, and interfitting means at the bottom of the first and second end posts to form a hinge connection between adjacent panels.
Claim 8
Dependent Claim
28 words
The combination of claim 5 wherein the interfitting means includes a cantilevered end at the bottom of one end post and a collar on the other end post.
Claim 9
Dependent Claim
25 words
The combination of claim 5 wherein the enclosure is formed by six panels, and the hinges allow the panels to collapse into two triangular configurations.
Claim 10
Dependent Claim
106 words
A haystack feeder comprising six identical panels of equal length hingedly connected to provide a rectangular enclosure having two end panels and four side panels; each panel including first and second ends, upper and lower horizontal members, and a plurality of inclined bars extending between the upper and lower members and spaced apart to define canted openings for receiving the heads of feeding animals; and hinge means interconnecting each first end with the second end of the adjacent panel and constructed and arranged to allow each pair of side panels to swing inwardly so that the enclosure assumes the general shape of two equilateral triangular configurations.
Claim 11
Dependent Claim
106 words
A haystack feeder comprising six identical panels of equal length hingedly connected to provide a rectangular enclosure having two end panels and four side panels; each panel including first and second ends, upper and lower horizontal members, and a plurality of inclined bars extending between the upper and lower members and spaced apart to define canted openings for receiving the heads of feeding animals; and hinge means interconnecting each first end with the second end of the adjacent panel and constructed and arranged to allow each pair of side panels to swing inwardly so that the enclosure assumes the general shape of two equilateral triangular configurations.
Claim 12
Dependent Claim
42 words
A haystack feeder as set forth in claim 8 wherein the lower horizontal member is spaced above the boTtom of the panel, and each panel includes means at the bottom below said lower horizontal member for retaining the hay within the enclosure.
Claim 13
Dependent Claim
67 words
A haystack feeder as set forth in claim 8 wherein each panel has an end post at each end, the upper and lower horizontal members extend between the end posts and therewith provide a frame, and the lower horizontal member is spaced above the bottom of the panel; and including a hay-retaining substantially imperforate barrier depending from the lower horizontal member to the bottom of the frame.
