Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
169 words
A harvesting machine including a vehicle adapted for advancement across a field having a crop thereon, said vehicle being provided with: a crop receiving body having a bed and a pair of spaced side walls extending upwardly from said bed; a crop pickup unit for lifting the crop off the field as the vehicle is advanced; an assembly including meanS disposed to receive the crop from said unit, direct the same to a level higher than the bed, and feed the crop into said body; and means for spreading the crop evenly throughout the body as the crop is fed thereinto, said body having structure normally disposed to cooperate with said side walls in confining said crop as the latter is fed into the body, said structure being shiftable with respect to said side walls downwardly toward said bed for compacting the crop from time to time in the body as the crop builds up therein to produce a stack conforming substantially in shape and size with the body.
Claim 2
Dependent Claim
169 words
A harvesting machine including a vehicle adapted for advancement across a field having a crop thereon, said vehicle being provided with: a crop receiving body having a bed and a pair of spaced side walls extending upwardly from said bed; a crop pickup unit for lifting the crop off the field as the vehicle is advanced; an assembly including meanS disposed to receive the crop from said unit, direct the same to a level higher than the bed, and feed the crop into said body; and means for spreading the crop evenly throughout the body as the crop is fed thereinto, said body having structure normally disposed to cooperate with said side walls in confining said crop as the latter is fed into the body, said structure being shiftable with respect to said side walls downwardly toward said bed for compacting the crop from time to time in the body as the crop builds up therein to produce a stack conforming substantially in shape and size with the body.
Claim 3
Dependent Claim
31 words
The invention of claim 1, said assembly being shiftable laterally of the body during advancement of the vehicle, there being power means operably coupled with the assembly for shifting the latter.
Claim 4
Dependent Claim
51 words
The invention of claim 2 wherein is provided a support for said unit and said assembly, and hitch means placing the body in tow behind said support, said hitch means being reciprocble transversely of the path of travel of the vehicle, said power means interconnecting the support and the hitch means.
Claim 5
Dependent Claim
29 words
The invention of claim 1, said spreading means including an extensible conveyor overlying the body and running fore and aft thereof; and means for extending and retracting the conveyor.
Claim 6
Dependent Claim
15 words
The invention of claim 4 wherein is provided means for raising and lowering said conveyor.
Claim 7
Dependent Claim
25 words
The invention of claim 4 wherein said assembly comprises an elevator, said conveyor having an endless belt disposed to form a part of said elevator.
Claim 8
Dependent Claim
22 words
The invention of claim 6 wherein is provided means for taking up the slack in the belt when the conveyor is retracted.
Claim 9
Dependent Claim
39 words
The invention of claim 1 wherein said structure includes a pluarlity of press units carried by the body for swinging movement to and from a position engaging the crop in the body and compressing the same toward said bed.
Claim 10
Dependent Claim
