Abstract
Abstract Disclosed is an apparatus for dispensing hay from large cylindrical bales formed of layers of hay spirally wound around a central axis. The preferred embodiment is comprised of a U-shaped frame detachably mountable on a three-point hitch of a tractor. The frame supports two rotatable, cylindrical rollers so oriented that a bale is supportable thereon. Powered rotation of one or both of the rollers causes the bale to rotate about its axis and the outermost layer of hay to be unwound from the bale and discharged between the rollers.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
156 words
A portable apparatus for dispensing hay from a cylindrical bale formed of layers of hay wound about a central axis comprising: first and second generally cylindrical, horizontal rollers, said rollers being substantially parallel to one another, rotatable about their cylindrical axes and so positioned relative to one another that a bale is supportable thereon with the cylindrical axis of the bale generally parallel to the axes of the rollers; support means for supporting said rollers above ground level; reversible motor means for selectively rotating said rollers in either direction about their axes independently of movement of said apparatus to thereby effect axial rotation of a bale supported on said rollers; power means for moving one of said rollers relative to the other to vary the spacing therebetween, and positioning means for positioning the support means near ground level to facilitate loading of a bale on the rollers by engagement thereof with the underside of a bale.
Claim 2
Dependent Claim
156 words
A portable apparatus for dispensing hay from a cylindrical bale formed of layers of hay wound about a central axis comprising: first and second generally cylindrical, horizontal rollers, said rollers being substantially parallel to one another, rotatable about their cylindrical axes and so positioned relative to one another that a bale is supportable thereon with the cylindrical axis of the bale generally parallel to the axes of the rollers; support means for supporting said rollers above ground level; reversible motor means for selectively rotating said rollers in either direction about their axes independently of movement of said apparatus to thereby effect axial rotation of a bale supported on said rollers; power means for moving one of said rollers relative to the other to vary the spacing therebetween, and positioning means for positioning the support means near ground level to facilitate loading of a bale on the rollers by engagement thereof with the underside of a bale.
Claim 3
Dependent Claim
256 words
A portable apparatus for dispensing hay from a cylindrical bale formed of layers of hay wound about a central axis comprising: first and second generally cylindrical, horizontal rollers, said rollers being substantially parallel to one another, rotatable about their cylindrical axes and so positioned relative to one another that a bale is supportable thereon with the cylindrical axis of the bale generally parallel to the axes of the rollers; support means for supporting said rollers above ground level, said support means including a generally U-shaped frame having an open end, said rollers extending between the legs of the frame, said first roller being positioned between said second roller and the closed end of said frame and said second roller being movable between a first location adjacent said first roller and a second location adjacent the open end of the frame; reversible motor means for selectively rotating said rollers in either direction about their axes independently of movement of said apparatus to thereby effect axial rotation of a bale supported on said rollers; power means for moving said second roller between said first and second locations; said second roller being so mounted on said frame that when the open end of the frame is positioned substantially at ground level, said second roller when at said second location is engagable with the underside of a bale resting on the ground, and positioning means for positioning said frame near ground level to facilitate loading of a bale on the rollers by engagement thereof with the underside of a bale.
Claim 4
Dependent Claim
256 words
A portable apparatus for dispensing hay from a cylindrical bale formed of layers of hay wound about a central axis comprising: first and second generally cylindrical, horizontal rollers, said rollers being substantially parallel to one another, rotatable about their cylindrical axes and so positioned relative to one another that a bale is supportable thereon with the cylindrical axis of the bale generally parallel to the axes of the rollers; support means for supporting said rollers above ground level, said support means including a generally U-shaped frame having an open end, said rollers extending between the legs of the frame, said first roller being positioned between said second roller and the closed end of said frame and said second roller being movable between a first location adjacent said first roller and a second location adjacent the open end of the frame; reversible motor means for selectively rotating said rollers in either direction about their axes independently of movement of said apparatus to thereby effect axial rotation of a bale supported on said rollers; power means for moving said second roller between said first and second locations; said second roller being so mounted on said frame that when the open end of the frame is positioned substantially at ground level, said second roller when at said second location is engagable with the underside of a bale resting on the ground, and positioning means for positioning said frame near ground level to facilitate loading of a bale on the rollers by engagement thereof with the underside of a bale.
Claim 5
Dependent Claim
21 words
The apparatus of claim 2 wherein said second roller is of a diameter substantially less than the radius of a bale.
