Abstract
Abstract An animal feeding station having an improved design to facilitate feeding of the animal. In particular, a manger that has a bottom portion approximating a hemispherical shape, side wall portions extending upward from the bottom portion as a conical tangent of the hemisphere, a front wall portion which extends vertically upward and is tangential to the aforesaid hemispherical portion and a rearwardly, upwardly sloped flat surface portion which generally conforms to the position of the animal's lower jaw when ingesting its food. Further, a shroud is provided over the manger which has a top wall sloped and disposed in a manner which restricts the vertical movement of the animal's head until the animal moves rearwardly. Another feature of the stall is the provision of slidably removable side panels, which permit the animal to eat in relative isolation and without the eye distraction caused by being able to see animals outside the stall. Further, a bar shaped in the form of an arch extends over the rear portion of the animal so as to preclude mounting of the feeding animal by stable mates. For use with electronic automatic feed control systems, there is provided a front panel through which the animal extends it head, which houses an encapsulated antenna having a metal reflector.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
98 words
In an automatic feeding station having an interrogator for receiving and responding to a transponder disposed on the animal feeding in the stall, said stall having a front panel through which the animal extends its head and a manger disposed outboard of said front panel, the improvement which comprises housing an antenna having a metal reflector in the front panel and encapsulating said antenna in a suitable dielectric so as to amplify the range of the transmitting component of the interrogator and concomitantly shield the antenna from conducting signals of transponders located outside the stall to the interrogator.
Claim 2
Dependent Claim
98 words
In an automatic feeding station having an interrogator for receiving and responding to a transponder disposed on the animal feeding in the stall, said stall having a front panel through which the animal extends its head and a manger disposed outboard of said front panel, the improvement which comprises housing an antenna having a metal reflector in the front panel and encapsulating said antenna in a suitable dielectric so as to amplify the range of the transmitting component of the interrogator and concomitantly shield the antenna from conducting signals of transponders located outside the stall to the interrogator.
Claim 3
Dependent Claim
187 words
In an animal feeding station having a stall with side rails supported by stanchion members, a front panel at one end of the stall through which the feeding animal extends its head, and a manger outboard of the front panel, the improvement comprising a manger having a bottom portion substantially hemispherical in shape, which bottom portion forms a cavity for receiving and containing the feed, said manger further including a conduit for introducing the feed to the bottom portion, which conduit is disposed outwardly and rearwardly of the bottom portion, whereby the introduction of feed into the manger is at a place to the side of and toward the rear of the animal's jaw when the animal is in feeding position, and an interrogator for receiving and responding to a transponder disposed on the animal feeding in the stall, an antenna having a metal reflector housed in said front panel, said antenna being encapsulated in a dielectric so as to amplify the range of the transmitting component of the interrogator and concomitantly shield the antenna from conducting signals of transponders located outside the stall to the interrogator.
Claim 4
Dependent Claim
187 words
In an animal feeding station having a stall with side rails supported by stanchion members, a front panel at one end of the stall through which the feeding animal extends its head, and a manger outboard of the front panel, the improvement comprising a manger having a bottom portion substantially hemispherical in shape, which bottom portion forms a cavity for receiving and containing the feed, said manger further including a conduit for introducing the feed to the bottom portion, which conduit is disposed outwardly and rearwardly of the bottom portion, whereby the introduction of feed into the manger is at a place to the side of and toward the rear of the animal's jaw when the animal is in feeding position, and an interrogator for receiving and responding to a transponder disposed on the animal feeding in the stall, an antenna having a metal reflector housed in said front panel, said antenna being encapsulated in a dielectric so as to amplify the range of the transmitting component of the interrogator and concomitantly shield the antenna from conducting signals of transponders located outside the stall to the interrogator.
Claim 5
Dependent Claim
99 words
In an animal feeding station, the combination of a stall and a manger at one end of the stall, said manger having a bottom portion substantially hemispherical in shape and only slightly larger than the muzzle of the animal for which the feeding station is designed, said bottom portion forming a cavity for receiving and containing the feed, and means disposed laterally and rearwardly of said bottom portion for introducing the feed thereto at a place to the side of and toward the rear of the animal's jaw, but under the jaw, when the animal is in feeding position.
Claim 6
Dependent Claim
99 words
In an animal feeding station, the combination of a stall and a manger at one end of the stall, said manger having a bottom portion substantially hemispherical in shape and only slightly larger than the muzzle of the animal for which the feeding station is designed, said bottom portion forming a cavity for receiving and containing the feed, and means disposed laterally and rearwardly of said bottom portion for introducing the feed thereto at a place to the side of and toward the rear of the animal's jaw, but under the jaw, when the animal is in feeding position.
Claim 7
Dependent Claim
60 words
The combination of claim 3, comprising also a shroud disposed above the manger and having a surface sloping downward and forward from a region overlying the rear of the manger, said sloping surface being positioned to limit the vertical head movement of the feeding animal so that the animal, on raising its head, will be forced rearward from feeding position.
Claim 8
Dependent Claim
61 words
The combination of claim 3, in which the stall has opposite side members supported by vertical members, the combination comprising also a bar rigidly secured to the stall at the rear portion thereof and spanning opposite side members, said bar being arched upwardly and positioned to preclude a stable mate outside the stall from mounting the animal feeding at the manger.
Claim 9
Dependent Claim
101 words
The combination of claim 3, in which the stall has opposite side members and a pair of front vertical members, the combination comprising also solid, opaque forward and rear panels on each of the opposite side members, there being limited spacing between the forward edges of the forward panels and said front vertical members, respectively, and there being limited spacing between the forward and rear panels on each of the opposite side members, so as to enable the animal in the stall to have eye contact with the area outside the stall as the animal moves rearwardly away from the manger.
Claim 10
Dependent Claim
75 words
The combination of claim 3, in which the manger also has a rear flat portion sloping upwardly from said bottom portion and with opposite side edges which converge toward said bottom portion, said flat portion being disposed at a level and angle to accommodate the normal position of the lower jaw of the feeding animal, the location of said feed introducing place allowing feed to flow to said bottom portion unobstructed by the feeding animal.
Claim 11
Dependent Claim
60 words
The combination of claim 7, comprising also a shroud disposed above the manger and having a surface sloping downward and forward from a region overlying the rear of the manger, said sloping surface being positioned to limit the vertical head movement of the feeding animal so that the animal, on raising its head, will be forced rearward from feeding position.
Claim 12
Dependent Claim
239 words
