Abstract

Abstract Apparatus for grinding both baled hay and small grains including a rotor having a combination of swinging hammers and fixed knives, a housing for the rotor with an opening at its forward side to admit material thereinto, a material-receiving chamber on the front side of the housing having a bale opening at its front side and a grain opening at its top side, a conveyor selectively operable to convey a bale rearwardly through the chamber and into the rotor housing, and a partition removably positionable in the chamber to extend downwardly and rearwardly from a point forwardly of the grain opening to the lower edge of the opening in the rotor housing, the partition when so positioned being operable to deflect grain deposited through the grain opening downwardly and rearwardly through the chamber and into the rotor housing. A vertically adjustable gate is included at the upper edge of the housing opening to control the height of the opening, the gate being raised for grinding bales and lowered for grinding grain. A shaft having a plurality of radially extending fingers thereon is mounted forwardly of the upper edge of the housing opening and is operative to engage and feed rearwardly through the opening the upper portion of a bale as the latter is conveyed rearwardly through the chamber.

Claim 3
Dependent Claim 156 words
The invention defined in claim 1 wherein said partition means includes a member pivotally connected to said chamber for swinging movement about a transverse horizontal axis disposed adjacent to the front edge of the grain opening between a lowered, grain position wherein said member extends generally between the side walls of said chamber from a point adjacent to the front edge of the grain opening downwardly and rearwardly toward the lower edge of the opening in said housing, said member when in its lowered position being operative to deflect grain deposited through said grain opening downwardly and rearwardly tHrough said chamber toward the opening in said housing, and a raised, bale position wherein said member extends generally between the side walls of said chamber from a point adjacent to the front edge of the grain opening rearwardly beneath said grain opening, said member when in its raised position being operative to substantially close said grain opening.
Claim 4
Dependent Claim 76 words
The invention defined in claim 2 wherein said partition member, when in its lowered position, has a lower edge terminating short of the lower edge of the opening in said housing, and wherein said partition means comprises a second member releasably positionable in the chamber to extend generally between the side walls thereof downwardly and rearwardly from the lower terminal edge of said first-mentioned partition member to the lower edge of the opening in said housing.
Claim 5
Dependent Claim 54 words
The invention defined in claim 1 including bale feeder means mounted to rotate about a transverse horizontal axis adjacent to the upper edge of the opening in said housing and operative to engage and feed rearwardly through said opening the upper portion of a bale as the latter is conveyed rearwardly through said chamber.
Claim 6
Dependent Claim 72 words
The invention defined in claim 4 wherein said bale feeder means comprises a rotatable shaft extending transversely between the side walls of said chamber, and a plurality of transversely spaced wheels with radially extending fingers mounted on said shaft for rotation therewith, said fingers being operative to engage and feed rearwardly through the opening in the housing the upper portion of a bale as the latter is conveyed rearwardly through said chamber.
Claim 7
Dependent Claim 191 words
The invention defined in claim 5 wherein said partition means includes a member pivotally connected to said chamber for swinging movement about a transverse horizontal axis disposed adjacent to the front edge of the grain opening between a lowered, grain position wherein said member extends generally between the side walls of said chamber from a point adjacent to the front edge of the grain opening downwardly and rearwardly toward the lower edge of the opening in said housing, said member when in its lowered position being operative to deflect grain deposited through said grain opening downwardly and rearwardly through said chamber toward the opening in said housing, and a raised, bale position wherein said member extends generally between the side walls of said chamber from a point adjacent to the front edge of the grain opening rearwardly beneath said grain opening, said member when in its raised position being operative to substantially close said grain opening and being disposed in underlying relation to said bale feeder shaft and above the lowermost extent of said radial fingers, said member having a plurality of slots formed therein through which said fingers are movable.
