Abstract
Abstract A stacking implement picks the precut crop off the ground, elevates the crop and blows it into a wagon. The crop is periodically compressed in the wagon, a crop-distributing deflector in the wagon is tilted in response to actuation of the compressor, and a stack unloading ramp is also raised and lowered by actuating the compressor.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
144 words
In a farm implement: a combination crop pickup and conveying unit having an open bottom housing, an upright delivery tube extending upwardly from the housing, and a pickup rotor mounted within said housing for lifting a crop from the ground through said open bottom and projecting the same into said tube; a container separate from the tube and shiftable relative thereto for receiving the crop from the tube; and a deflector shiftably secured to the container therewithin for distributing the crop within the container as the crop is fed thereinto, said contaIner being sectional, including a first, hollow, open top section and a second vertically reciprocable, hollow, open bottom section, said sections receiving the crop when the second section is raised, said deflector being shiftably attached to the second section therewithin for movement to adjusted positions in response to reciprocation of the second section.
Claim 2
Dependent Claim
144 words
In a farm implement: a combination crop pickup and conveying unit having an open bottom housing, an upright delivery tube extending upwardly from the housing, and a pickup rotor mounted within said housing for lifting a crop from the ground through said open bottom and projecting the same into said tube; a container separate from the tube and shiftable relative thereto for receiving the crop from the tube; and a deflector shiftably secured to the container therewithin for distributing the crop within the container as the crop is fed thereinto, said contaIner being sectional, including a first, hollow, open top section and a second vertically reciprocable, hollow, open bottom section, said sections receiving the crop when the second section is raised, said deflector being shiftably attached to the second section therewithin for movement to adjusted positions in response to reciprocation of the second section.
Claim 3
Dependent Claim
144 words
In a farm implement: a combination crop pickup and conveying unit having an open bottom housing, an upright delivery tube extending upwardly from the housing, and a pickup rotor mounted within said housing for lifting a crop from the ground through said open bottom and projecting the same into said tube; a container separate from the tube and shiftable relative thereto for receiving the crop from the tube; and a deflector shiftably secured to the container therewithin for distributing the crop within the container as the crop is fed thereinto, said contaIner being sectional, including a first, hollow, open top section and a second vertically reciprocable, hollow, open bottom section, said sections receiving the crop when the second section is raised, said deflector being shiftably attached to the second section therewithin for movement to adjusted positions in response to reciprocation of the second section.
Claim 4
Dependent Claim
144 words
In a farm implement: a combination crop pickup and conveying unit having an open bottom housing, an upright delivery tube extending upwardly from the housing, and a pickup rotor mounted within said housing for lifting a crop from the ground through said open bottom and projecting the same into said tube; a container separate from the tube and shiftable relative thereto for receiving the crop from the tube; and a deflector shiftably secured to the container therewithin for distributing the crop within the container as the crop is fed thereinto, said contaIner being sectional, including a first, hollow, open top section and a second vertically reciprocable, hollow, open bottom section, said sections receiving the crop when the second section is raised, said deflector being shiftably attached to the second section therewithin for movement to adjusted positions in response to reciprocation of the second section.
Claim 5
Dependent Claim
41 words
In a farm implement as claimed in claim 1 wherein said deflector is swingable up and down about a horizontal axis and is provided with means operable to swing the deflector upwardly relative to the second section as the latter ascends.
Claim 6
Dependent Claim
31 words
In a farm implement as claimed in claim 2; and means for limiting the extent of downward swinging movement of the deflector relative to the second section as the latter descends.
Claim 7
Dependent Claim
45 words
In a farm implement as claimed in claim 1 wherein said container is elongated and the crop is projected into one end thereof normally toward the opposite end thereof, said deflector being movable to a position for deflecting the crop downwardly toward said one end.
Claim 8
Dependent Claim
30 words
In a farm implement as claimed in claim 4 wherein said deflector is provided with means for distributing the crop laterally of the container as the crop engages the deflector.
Claim 9
Dependent Claim
51 words
In a farm implement as claimed in claim 1 wherein said pickup and conveying unit is operable to provide an air blast for projecting the crop into the container and said deflector is provided with means for exhausting the air from the crop as the latter is distributed by the deflector.
Claim 10
Dependent Claim
49 words
In a farm implement as claimed in claim 1 wherein is provided cable means anchored at one end thereof to the first section, attached at the opposite end thereof to the deflector and operably coupled with the second section for effecting said adjustment during reciprocation of the second section.
Claim 11
Dependent Claim
50 words
In a farm implement as claimed in claim 1 wherein said second section has an upper corner at one end thereof, said deflector being disposed for movement into said corner in response to pressure thereon by the crop in the container as the second section descends to compress the crop.
Claim 12
Dependent Claim
118 words
In a stack forming implement: a mobile container defining a chamber for receiving crop to be formed into a stack; pickup and delivery means disposed adjacent said container and operable to direct a stream of projected crop into said chamber; mechanism for periodically compacting crop collecting in the chamber and including a compressor reciprocable vertically on the container; a shiftable deflector mounted for movement into and out of a position for deflecting the projected crop toward one part of the chamber; and structure coupled with said deflector and operable in response to actuation of said mechanism to effect said movement of the deflector when the compressor is disposed at a sufficient height to receive the crop stream therebeneath.
Claim 13
Dependent Claim
118 words
In a stack forming implement: a mobile container defining a chamber for receiving crop to be formed into a stack; pickup and delivery means disposed adjacent said container and operable to direct a stream of projected crop into said chamber; mechanism for periodically compacting crop collecting in the chamber and including a compressor reciprocable vertically on the container; a shiftable deflector mounted for movement into and out of a position for deflecting the projected crop toward one part of the chamber; and structure coupled with said deflector and operable in response to actuation of said mechanism to effect said movement of the deflector when the compressor is disposed at a sufficient height to receive the crop stream therebeneath.
Claim 14
Dependent Claim
29 words
In a stack forming implement as claimed in claim 9, wherein said structure is inoperable to cause said movement of the deflector when the compressor is below said height.
Claim 15
Dependent Claim
38 words
In a stack forming implement as claimed in claim 10, wherein said deflector is provided with limit means for precluding further movement of the deflector beyond said crop deflecting position thereof when the compressor is below said height.
Claim 16
Dependent Claim
55 words
In a stack forming implement as claimed in claim 11, wherein said structure includes a cable connected to said deflector for lowering of the deflector into said position as the compressor is lowered, said limit means being disposed to relieve the load of the deflector from said cable when the compressor is below said height.
Claim 17
Dependent Claim
18 words
In a stack forming implement as claimed in claim 12, wherein said deflector is mounted on said compressor.
Claim 18
Dependent Claim
35 words
In a stack forming implement as claimed in claim 13, wherein said cable is connected at its opposite ends to the deflector and to the container, said compressor engaging the cable intermediate its opposite ends.
