Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
130 words
In combination in a combine harvester having a pivotally mounted thresher housing including a pair of spaced apart sidewalls joined by a floor, a header mounted on the forward end of said housing, a threshing cylinder carried by said harvester, a feeder beater mounted in transversely extending relation to said housing in overlying proximate relation to said floor and in feeding relation to said cylinder, said feeder beater being pivotally supported from pivot members pivoted on transversely aligned stub shafts attached to said sidewalls to provide an axis substantially the same height as the axis of said beater when said heater is in its lowest position for permitting upward swinging movement of said feeder beater in transversely aligned openings in said sidewalls, and power means for driving said feeder beater.
Claim 2
Dependent Claim
130 words
In combination in a combine harvester having a pivotally mounted thresher housing including a pair of spaced apart sidewalls joined by a floor, a header mounted on the forward end of said housing, a threshing cylinder carried by said harvester, a feeder beater mounted in transversely extending relation to said housing in overlying proximate relation to said floor and in feeding relation to said cylinder, said feeder beater being pivotally supported from pivot members pivoted on transversely aligned stub shafts attached to said sidewalls to provide an axis substantially the same height as the axis of said beater when said heater is in its lowest position for permitting upward swinging movement of said feeder beater in transversely aligned openings in said sidewalls, and power means for driving said feeder beater.
Claim 3
Dependent Claim
95 words
The combination recited in claim 1 and wherein said means for driving said feeder beater includes a drive sprocket mounted on one of said stub shafts, a sprocket attached to said feeder beater, a chain tightening means attached to said member, a drive chain connecting said shaft sprocket to said beater sprocket and said contacting chain tightening means, said sprockets, chain and tightening means being so arranged that said beater may be raised up by an overload of material passing thereunder without a change in the driving relationships of said sprockets and chain tightening means.
Claim 4
Dependent Claim
31 words
The combination recited in claim 2 and wherein said chain tightener is positioned to maintain a driving relation between said shaft and said beater in all adjusted positions of said beater.
Claim 5
Dependent Claim
29 words
The combination recited in claim 3 and wherein said chain tightening means moves with said beater about said drive sprocket and thereby retains a driving tension in said chain.
Claim 6
Dependent Claim
25 words
The combination recited in claim 4 and wherein said chain tightening means lowers when said beater lowers to maintain a driving tension in said chain.
Claim 7
Dependent Claim
29 words
The combination recited in claim 5 and wherein a pair of stop members are attached to said pivot members for limiting the raising and lowering of said feeder beater.
Claim 8
Dependent Claim
38 words
The combination recited in claim 6 and wherein one end of said feeder beater can raise up responsive to material being moved under said beater independently of whether the other end of said beater raises up or not.
