Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
A two row corn snapping header for use in combination with a forage harvester comprising: a main frame including beam extending at right angles to the path of travel of said harvester across both rows; left and right transverse beam assemblies, each of said assemblies having a first end pivotally mounted on said main frame beam for swinging about a generally vertical axis and a second end attachable to said frame beam in one of a plurality of positions, the portion of said beam assembly between said first and second ends being a transverse beam forwardly offset from said main frame beam at an obtuse angle to the path of travel of said harvester; a corn snapping unit mounted on each of said transverse beam assemblies and having a crop passage disposed perpendicularly of said transverse beam for receiving corn stalks, said corn snapping units having means for removing the corn ears from the stalks and for moving them rearwardly to said forage harvester, and means operatively associated with said forage harvester for driving said snapping units.
Claim 2
Dependent Claim
177 words
A two row corn snapping header for use in combination with a forage harvester comprising: a main frame including beam extending at right angles to the path of travel of said harvester across both rows; left and right transverse beam assemblies, each of said assemblies having a first end pivotally mounted on said main frame beam for swinging about a generally vertical axis and a second end attachable to said frame beam in one of a plurality of positions, the portion of said beam assembly between said first and second ends being a transverse beam forwardly offset from said main frame beam at an obtuse angle to the path of travel of said harvester; a corn snapping unit mounted on each of said transverse beam assemblies and having a crop passage disposed perpendicularly of said transverse beam for receiving corn stalks, said corn snapping units having means for removing the corn ears from the stalks and for moving them rearwardly to said forage harvester, and means operatively associated with said forage harvester for driving said snapping units.
Claim 3
Dependent Claim
120 words
A multi-row corn snapping header comprising; a main frame extending transversely across all rows; a transverse beam assembly having a first end pivotally mounted adjacent the end of said transverse frame about a generally vertical axis and a second end adapted to be attached to a laterally inner portion of said frame, the medial portion of said beam assembly being a transverse beam forwardly offset from said main frame at an obtuse angle to the direction of travel, a corn snapping unit mounted on said transverse beam and having a crop passage for receiving corn stalks, said snapping unit having means for removing ears from said corn stalks, and moving said ears rearwardly, and means for driving said snapping unit.
Claim 4
Dependent Claim
120 words
A multi-row corn snapping header comprising; a main frame extending transversely across all rows; a transverse beam assembly having a first end pivotally mounted adjacent the end of said transverse frame about a generally vertical axis and a second end adapted to be attached to a laterally inner portion of said frame, the medial portion of said beam assembly being a transverse beam forwardly offset from said main frame at an obtuse angle to the direction of travel, a corn snapping unit mounted on said transverse beam and having a crop passage for receiving corn stalks, said snapping unit having means for removing ears from said corn stalks, and moving said ears rearwardly, and means for driving said snapping unit.
Claim 5
Dependent Claim
45 words
The invention in accordance with claim 2 and a second transverse beam assembly pivotally mounted at the other end of said frame in the same manner as said transverse beam assembly, and a second corn snapping unit being mounted on said second transverse beam assembly.
Claim 6
Dependent Claim
38 words
The invention in accordance with claim 1 or claim 3 and a single transverse driveline extending laterally across said rows for driving said snapping units, and universal joint means being disposed in said driveline between said snapping units.
Claim 7
Dependent Claim
41 words
The invention in accordance with claim 4 and said driveline extending transversely beyond one of said snapping units to a fixed rotatable mounting on said frame and a universal joint disposed between said one snapping unit and said rotatable fixed mounting.
Claim 8
Dependent Claim
35 words
The invention in accordance with claim 5 and said universal joint between said one snapping unit and said fixed rotatable mounting lying on the pivot axis of said transverse beam assembly mounting said snapping unit.
