Abstract

An anti-spill, self-righting animal feeder particularly suitable for horses comprising a hollow bowl-shaped vessel with means on the top rim of the vessel to limit the degree of tipping from the vertical including a radially outwardly extending flange mounted on the top rim and an internal inwardly and downwardly extending flange integral therewith defining a trap for feed at the top of the bowl together with weight means on the bottom of the vessel such that the center of gravity of the feeder rises when it is tipped from the vertical.

Claims

1. An anti-spill, self-righting livestock feeder for granular feed, the livestock feeder comprising:

a) a hollow vessel for placement on a support surface defining an open top, a flat and generally horizontal bottom and a side wall, the side wall being arcuate outwardly and upwardly along at least a portion thereof extending from the bottom;

b) a rim at the top of the vessel, said rim defining a plane substantially parallel with the generally horizontal bottom;

c) an anti-spill ring comprising a radially outwardly extending flange, a radially inwardly and downwardly extending flange and a plurality of holes located there around,

said outwardly extending flange limiting the degree of displacement of said plane when the vessel is tipped by engaging with the support surface thereby preventing significant spillage of feed as the vessel is tipped, and

said radially inwardly and downwardly extending flange extending inwardly from said side wall and downwardly from said rim and defining an opening for permitting an animal to insert a portion of the animal'"'"'s head within the opening to consume feed from the feeder;

d) a blind trap defined between the upper portion of the side wall and the radially inwardly and downwardly extending flange to trap significant quantities of granular feed from being ejected from the opening as an animal is feeding;

e) a weight for urging the plane toward its original position when the vessel is tipped from resting on its bottom;

f) said rim of the vessel having a radially extending mounting lip provided with a plurality of holes for aligning with the plurality of holes of the anti-spill ring;

g) a plurality of fasteners extending through said holes of said rim and said anti-spill ring so as to detachably secure said anti-spill ring to said vessel; and

h) a fluid discharge means positioned within the sidewall of the vessel in the area of the blind trap such that fluid within said vessel may drain from the interior of the vessel while preventing the escape of granular feed therefrom.

2. The livestock feeder of claim 1, further comprising the weight being located on the exterior of the bottom of the vessel, said weight being sufficient to cause the vessel to right itself so as to return the plane substantially parallel to the surface on which the bottom is resting.

3. The livestock feeder of claim 2, wherein said bottom of the vessel is provided with an annular recess and wherein said weight is annular in shape such that said annular weight is detachably secured within said annular recess of the vessel.

4. The livestock feeder of claim 2, wherein said weight is mounted flush with the exterior bottom of the vessel and, the interior surface of the vessel is continuously smooth and the bottom merges arcuately with the arcuate and upwardly extending side wall.

5. The livestock feeder of claim 1, wherein said fluid discharge means comprises a grated water drain, said water drain located immediately proximal to the rim and consists of a generally U-shaped opening and a pair of spaced-apart, upstanding posts.

6. The livestock feeder of claim 1, wherein the inwardly and downwardly extending flange depends from the rim at an angle of about 45 degrees from the plane.

7. The livestock feeder of claim 1, wherein said radially outwardly extending flange is provided with a downwardly extending lip.
