Abstract
Abstract A deflector panel is pivotally mounted within the straw hood of a combine and is disposable between a first position wherein residue material emanating from the combine is deflected into a straw chopper and a second position wherein the emanating material is deflected through the residue outlet of the straw hood, forwardly of the straw chopper, and discharged onto the ground.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
In a combine having a hollow residue receiving discharge hood provided with a downwardly facing residue outlet for receiving residue material emanating from said combine and a residue treating means, such as a straw chopper or the like, mounted in the vicinity of said outlet for treating said residue material and discharging the same onto the ground, the improvement comprising: a deflector mounted within said hood above said treating means and adapted to be disposed between a first position wherein said emanating residue material is deflected into said treating means and a second position wherein said emanating residue material is deflected through said residue outlet to thereby bypass said treating means; and means for mounting said deflector for movement between said first and second positions.
Claim 2
Dependent Claim
125 words
In a combine having a hollow residue receiving discharge hood provided with a downwardly facing residue outlet for receiving residue material emanating from said combine and a residue treating means, such as a straw chopper or the like, mounted in the vicinity of said outlet for treating said residue material and discharging the same onto the ground, the improvement comprising: a deflector mounted within said hood above said treating means and adapted to be disposed between a first position wherein said emanating residue material is deflected into said treating means and a second position wherein said emanating residue material is deflected through said residue outlet to thereby bypass said treating means; and means for mounting said deflector for movement between said first and second positions.
Claim 3
Dependent Claim
56 words
In a combine as defined in claim 1, wherein said deflector is a panel with the upper edge of the panel being pivotally mounted on an upper surface of said discharge hood such that the lower edge of said panel travels in an arcuate path as said panel is moved between its first and second positions.
Claim 4
Dependent Claim
54 words
In a combine as defined in claim 2, wherein: said discharge hood includes a pair of longitudinally extending space-apart sidewalls joined by a top wall and a rear wall; said panel is a rigid member extending laterally between said sidewalls, upwardly to said top wall and downwardly to a position above said treating means.
Claim 5
Dependent Claim
22 words
In a combine as defined in claim 3, further comprising fastening means for retaining said panel in said first and second positions.
Claim 6
Dependent Claim
45 words
In a combine as defined in claim 1, wherein said deflector is an upright panel which extends transversely between the sidewalls of said hood and has its upper end pivotally mounted within and to said hood and its lower end extending above said treating means.
Claim 7
Dependent Claim
36 words
In a combine as defined in claim 1, wherein the deflector is generally vertical in one of its first and second positions and is generally inclined in the other one of its first and second positions.
Claim 8
Dependent Claim
20 words
In a combine as defined in claim 6, wherein the deflector is upwardly and forwardly inclined in said first position.
Claim 9
Dependent Claim
88 words
In a combine as defined in claim 1, wherein: said treating means is mounted within the vicinity of the rearmost portion of the outlet of said discharge hood; and said deflector is pivotally mounted at its upper end to an upper portion of said discharge hood and is forwardly inclined in its first position to deflect the emanating residue material into said treating means and is generally vertically disposed in its second position to deflect the emanating residue material forwardly of said treating means and through said outlet.
