Abstract
Abstract A corn header for combines wherein the combine moving into a corn field acts first to cut the corn stalks and direct them onto a draper roll. The corn stalks are then moved in a generally longitudinal direction into engagement with snapping rolls, which pull the stalks therethrough, snap the corn off and deposit it onto transversely moving gathering chains which direct the corn into a centrally located conveyor which carries the corn into a storage area.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
250 words
A corn header for use with a combine for delivering ears of corn from standing stalks to the combine, said header comprising first and second longitudinally extending rearwardly moving conveyors arranged in end-to-end relation with said first conveyor having a transverse dimension substantially greater than said second conveyor, said second conveyor being centrally disposed relative to said first conveyor to define open areas rearwardly of said first conveyor on opposite sides of said second conveyor; first and second pairs of snapping rolls on opposite sides of said second conveyor and extending transversely substantially the width of said open areas for receiving ear bearing portions of stalks to be harvested; first and second vertically spaced cutters disposed below and above said first conveyor and being coextensive with the transverse dimension of said first conveyor; and transversely moving conveyor means disposed below said snapping rolls and rearwardly of the rear end of said first conveyor for receiving ears severed by said snapping rolls and for delivering the ears to said second conveyor, said first cutter severing corn stalks to be harvested below the ear bearing portion and the second cutter severing the nonbearing top portions of the stalks with the ear bearing portion deposited on said first conveyor and deLivered to said snapping rolls for severing the ears from the stalks and delivering the several ears to said second conveyor by said conveyor means with all of the stalk being deposited into the open area on opposite sides of said second conveyor.
Claim 2
Dependent Claim
250 words
A corn header for use with a combine for delivering ears of corn from standing stalks to the combine, said header comprising first and second longitudinally extending rearwardly moving conveyors arranged in end-to-end relation with said first conveyor having a transverse dimension substantially greater than said second conveyor, said second conveyor being centrally disposed relative to said first conveyor to define open areas rearwardly of said first conveyor on opposite sides of said second conveyor; first and second pairs of snapping rolls on opposite sides of said second conveyor and extending transversely substantially the width of said open areas for receiving ear bearing portions of stalks to be harvested; first and second vertically spaced cutters disposed below and above said first conveyor and being coextensive with the transverse dimension of said first conveyor; and transversely moving conveyor means disposed below said snapping rolls and rearwardly of the rear end of said first conveyor for receiving ears severed by said snapping rolls and for delivering the ears to said second conveyor, said first cutter severing corn stalks to be harvested below the ear bearing portion and the second cutter severing the nonbearing top portions of the stalks with the ear bearing portion deposited on said first conveyor and deLivered to said snapping rolls for severing the ears from the stalks and delivering the several ears to said second conveyor by said conveyor means with all of the stalk being deposited into the open area on opposite sides of said second conveyor.
Claim 3
Dependent Claim
28 words
A corn header as recited in claim 1 including the further improvement of means preventing the nonbearing top portions of said severed stalks from engaging said snapping rolls.
Claim 4
Dependent Claim
51 words
A corn header as recited in claim 1, in which said conveyor means comprises a pair of gathering chains, said gathering chains being positioned to engage said ears of corn severed from said stalks by said snapping rolls and oppositely directed to carry said ears of corn to said second conveyor.
Claim 5
Dependent Claim
36 words
A corn header as defined in claim 1, including the further improvement of a beater engaging said stalks as they are severed by said first cutter to move said stalks toward engagement with said first conveyor.
Claim 6
Dependent Claim
38 words
A corn header as recited in claim 4, and having an interconnected driving means for driving both of said cutters, said conveyor, said first and second conveyors, said snapping rolls and said beater from a single power source.
Claim 7
Dependent Claim
69 words
A corn header as recited in claim 1, in which said first conveyor comprises a pair of parallel belts in laterally spaced relationship, and said pairs of snapping rolls are respectively aligned with the ends of said parallel belts, the improvement of first guide means above the space between said parallel belts for directing the cut stalks toward one of said pairs of snapping rolls, and second guide means.
Claim 8
Dependent Claim
32 words
A corn header as defined in claim 1, in which said conveyor means comprises a transversely extending auger conveyor having left and right hand flights on opposite sides of said second conveyor.
Claim 9
Dependent Claim
150 words
In a harvesting machine having a crop treating section, a corn header for feeding ears of corn to be harvested to said crop treating section and comprising first and second end-to-end rearwardly moving conveyors with said second conveyor having a transverse dimension substantially less than said first conveyor and having opposite edges transversely spaced from adjacent edges of said first conveyor; cutter means above and below said first conveyor for severing stalks of corn above and below the ear bearing portion with the ear bearing portion deposited on said first conveyor; first and second pairs of snapping rolls respectively located on opposite sides of said second conveyor and transversely aligned with the end of said first conveyor for receiving the ear bearing portions of said stalks and removing the ears therefrom; and transversely moving conveyor means for receiving the ears of corn and delivering said ears to said second conveyor.
Claim 10
Dependent Claim
150 words
In a harvesting machine having a crop treating section, a corn header for feeding ears of corn to be harvested to said crop treating section and comprising first and second end-to-end rearwardly moving conveyors with said second conveyor having a transverse dimension substantially less than said first conveyor and having opposite edges transversely spaced from adjacent edges of said first conveyor; cutter means above and below said first conveyor for severing stalks of corn above and below the ear bearing portion with the ear bearing portion deposited on said first conveyor; first and second pairs of snapping rolls respectively located on opposite sides of said second conveyor and transversely aligned with the end of said first conveyor for receiving the ear bearing portions of said stalks and removing the ears therefrom; and transversely moving conveyor means for receiving the ears of corn and delivering said ears to said second conveyor.
Claim 11
Dependent Claim
58 words
A corn header as defined in claim 8, including guide means comprising first guide members disposed between adjacent ends of the respective pairs of snapping rolls for guiding the ear bearing portion of said stalks to said snapping rolls and second guide members for guiding the upper nonear bearing portions of said stalks away from said conveyor means.
