Abstract
Abstract A mobile carriage has vertical bush engaging frames in opposed relation to engage opposite sides of the bushes as the carriage advances along a crop row. The frames are divided horizontally into upper and lower sections. The frames are further divided vertically into leading and trailing sections. The frame sections are vertically pivoted at their leading ends and have rearwardly extending vertically spaced flexible bush engaging rods. Each pair of opposed sections has one section that is spring biased inwardly toward the side of the bush, while the opposed section is vibratorily oscillated about its pivot to engage and shake the opposite side of the bush. The leading sections on one side of the machine are oscillated, while the trailing sections on the opposite side are oscillated. Separate and independent drive motor oscillate the driven frame sections on opposite sides of the machine; while the upper and lower driven frame sections can be oscillated in different and variable phase sequence.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
145 words
In a mobile harvesting machine adapted to be advanced along a crop row in straddling relation with crop engaging assemblies arranged to simultaneously engage opposite sides of the crop and extending vertically to act on the major portion of the crop, a driven crop engaging frame having its leading edge pivotably mounted on one side of said machine with its trailing edge swingable laterally away from said one side, drive means connected to said driven frame for oscillating said driven frame about its pivot towards and away from said one side, a second crop engaging frame opposed to said driven frame and having its leading edge pivotably mounted on the opposite side of the machine, and yieldable means connected between said second frame and said machine and biasing the trailiNg edge of said second frame inwardly of said machine and away from said opposite side.
Claim 2
Dependent Claim
145 words
In a mobile harvesting machine adapted to be advanced along a crop row in straddling relation with crop engaging assemblies arranged to simultaneously engage opposite sides of the crop and extending vertically to act on the major portion of the crop, a driven crop engaging frame having its leading edge pivotably mounted on one side of said machine with its trailing edge swingable laterally away from said one side, drive means connected to said driven frame for oscillating said driven frame about its pivot towards and away from said one side, a second crop engaging frame opposed to said driven frame and having its leading edge pivotably mounted on the opposite side of the machine, and yieldable means connected between said second frame and said machine and biasing the trailiNg edge of said second frame inwardly of said machine and away from said opposite side.
Claim 3
Dependent Claim
145 words
In a mobile harvesting machine adapted to be advanced along a crop row in straddling relation with crop engaging assemblies arranged to simultaneously engage opposite sides of the crop and extending vertically to act on the major portion of the crop, a driven crop engaging frame having its leading edge pivotably mounted on one side of said machine with its trailing edge swingable laterally away from said one side, drive means connected to said driven frame for oscillating said driven frame about its pivot towards and away from said one side, a second crop engaging frame opposed to said driven frame and having its leading edge pivotably mounted on the opposite side of the machine, and yieldable means connected between said second frame and said machine and biasing the trailiNg edge of said second frame inwardly of said machine and away from said opposite side.
Claim 4
Dependent Claim
145 words
In a mobile harvesting machine adapted to be advanced along a crop row in straddling relation with crop engaging assemblies arranged to simultaneously engage opposite sides of the crop and extending vertically to act on the major portion of the crop, a driven crop engaging frame having its leading edge pivotably mounted on one side of said machine with its trailing edge swingable laterally away from said one side, drive means connected to said driven frame for oscillating said driven frame about its pivot towards and away from said one side, a second crop engaging frame opposed to said driven frame and having its leading edge pivotably mounted on the opposite side of the machine, and yieldable means connected between said second frame and said machine and biasing the trailiNg edge of said second frame inwardly of said machine and away from said opposite side.
Claim 5
Dependent Claim
32 words
A harvesting machine as defined in claim 1 in which each of said frames comprises a plurality of vertically spaced crop engaging rods that are freely self supporting at their rear ends.
Claim 6
Dependent Claim
37 words
A harvesting machine as defined in claim 2 in which said crop engaging rods are individually flexible and yieldable to pressure against the crop created by the combined actions of said drive means and said yieldable means.
Claim 7
Dependent Claim
59 words
A harvesting machine as defined in claim 1 in which said crop engaging frames on both sides of the machine are divided horizontally into upper and lower crop engaging sections, there being two drive means connected to separately oscillate the upper and lower drive frame sections, and two yieldable means connected to yieldably bias the two opposed frame sections.
Claim 8
Dependent Claim
109 words
A harvesting machine as defined in claim 1 in which said crop engaging assemblies on both sides of the machine are divided vertically into leading and trailing tandem sections, there being a driven crop engaging frame at the leading end of one assembly and another driven crop engaging frame at the trailing end of the opposite assembly, there being two crop engaging frames each opposed to a different one of said driven frames, two drive means connected to separately oscillate said driven crop engaging frames on opposite sides of the machine, and two yieldable means connected to separately bias the opposite crop engaging frames opposed to said driven frames.
Claim 9
Dependent Claim
59 words
A harvesting machine as defined in claim 5 in which said crop engaging frames on both sides of the machine are divided horizontally into upper and lower crop engaging sections, there being two drive means connected to separately oscillate the upper and lower drive frame sections, and two yieldable means connected to yieldably bias the two opposed frame sections.
Claim 10
Dependent Claim
32 words
A harvesting machine as defined in claim 6 in which each of said frames comprises a plurality of vertically spaced crop engaging rods that are freely self supporting at their rear ends.
Claim 11
Dependent Claim
37 words
A harvesting machine as defined in claim 7 in which said crop engaging rods are individually flexible and yieldable to pressure against the crop created by the combined actions of said drive means and said yieldable means.
Claim 12
Dependent Claim
29 words
A harvesting machine as defined in claim 4 in which said two drive means are connectable to oscillate said upper and lower driven frame sections in different phase relation.
Claim 13
Dependent Claim
56 words
A harvesting machine as defined in claim 5 in which said crop engaging frames comprise vertically spaced and longitudinally extending rods that are freely self supporting at their trailing ends, the trailing ends of the rods in the leading frame sections extending rearwardly into lateral overlapping relation to the leading edges of the trailing frame sections.
Claim 14
Dependent Claim
67 words
A harvesting machine as defined in claim 1 in which said drive means is arranged to oscillate said driven crop engaging frame at an amplitude which will swing its trailing edge of the frame across the center longitudinal plane of the machine, said yieldable means being arranged to yieldably bias the trailing edge of said second crop engaging frame across the center longitudinal plane of the machine.
Claim 15
Dependent Claim
81 words
A harvesting machine as defined in claim 11 in which each of said crop engaging frames comprises a plurality of vertically spaced and longitudinally extending crop engaging rods that are self supporting and unconnected at their trailing ends, said crop engaging rods being individually flexible and yieldable to pressure against the crop created by said drive means and said yieldable means, said drive means being arranged to oscillate said driven crop engaging frame at between 100 and 400 cycles per minute.
