Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
In a baler for crop material having a frame including a bale chamber with a side opening through which crop material is fed into said bale chamber for the formation of a bale, a crop material feeding chamber extending to said side opening of the bale chamber, a feeding unit carried by said frame for feeding crop material in said feeding chamber toward said side opening, and orbiting packer finger means carried by said frame for feeding crop material advanced by said feeding unit into said bale chamber, the combination of means for adjusting the attitude of said packer finger means to alter the orbital path thereof and thereby control bale shape comprising an attitude adjusting link having one end portion pivotally mounted on the frame and another end portion swingably connected to said packer finger means, and an operating handle for changing the effective length of said attitude link between said portions to effect adjustment of the attitude of said packer finger means, said operating handle being located outboard of said feeding chamber whereby it can be operated with safety when the baler is running.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
76 words
A construction in accordance with claim 1 wherein said packer finger means includes packer finger arms provided with a trunnion having a threaded bore therein, and wherein said attitude adjusting link comprises a rod threaded at one end into said trunnion bore, a pivotal mounting for said link adjacent its other end, and an operating handle secured to said link at said other end for rotating said rod to adjust the attitude of said packer fingers.
Claim 4
Dependent Claim
105 words
A construction in accordance with claim 1 wherein said packer finger means comprises a rotatable crank, packer fingers carried by said crank having an extension arm, a trunnion mounted in said arm, a transverse threaded bore in said trunnion, and wherein said attitude adjusting link comprises a rotatable rod threaded at one end into the bore of said trunnion, a trunnion adjacent the other end of said rod for pivotally mounting said rod, a fixed support bracket for said latter trunnion, and an operating handle secured to said rod at said other end for rotating the rod to adjust the attitude of the packer fingers.
Claim 5
Dependent Claim
137 words
A construction in accordance with claim 1 wherein said packer finger means comprises a rotatable crank and crank pin, a packer finger carrier mounted on said crank pin, depending packer fingers secured to said carrier, and an upwardly extending arm secured to said carrier, a trunnion amounted adjacent the free end of said arm and a threaded transverse bore in said trunnion, and wherein said attitude adjusting link comprises a rod having a screw thread at one end threaded into the bore of said trunnion, a trunnion member carried by said rod adjacent its other end, a fixed bracket for pivotally mounting said trunnion member, spaced bearings for said rod carried by said trunnion member, and an operating handle secured on said rod outboard of said trunnion member and bracket for rotating said rod to make adjustments.
Claim 6
Dependent Claim
32 words
A construction in accordance with claim 2 wherein rotation of said rod in one direction decreases its effective length and rotation of said rod in the opposite direction increases its effective length.
Claim 7
Dependent Claim
20 words
A construction in accordance with claim 5 and further including means for limiting adjustments of the rod in said directions.
