Abstract
Abstract The draft tongue of a peanut combine carries a gear box adapted to be connected to the power take-off of a tractor and is connected to the tractor drawbar in such a way that the forward end of the tongue operates in a fixed vertical position in relation to the ground. The tongue is connected to the frame of the combine by transversely aligned horizontal bushings through one of which the output shaft of the gear box projects axially. Push-pull cylinders effect pivotal movement of the combine relative to the tongue to raise and lower the pick-up head of the combine relative to the ground surface.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
226 words
In combination with a peanut combine or like machine having an elongate body provided with a crop pick-up head at its forward end which requires drive from the power take-off of an associated tractor, support wheels for the body to allow the pick-up head to be adjusted in a vertical plane about the axis of the support wheels; a draft tongue assembly projecting forwardly from said body and adapted to be connected to the associated tractor in such fashion as allows substantially no movement between the draft tongue assembly and the associated tractor in a vertical plane; pivot connections means between said draft tongue assembly and said body for establishing a horizontal transverse pivot axis connection therebetween to allow vertical movement of said pickup head about said axis of the support wheels; drive coupling means on said draft tongue assembly having an input shaft disposed at a selected height alignment with the power take-off of the associated tractor and having an output shaft coaxial with said transverse pivot axis between the draft tongue assembly and said body whereby vertical movement of said pick-up head has minimum effect on the height alignment of said input path nor does it affect the alignment of said output shaft relative to said body; and power means connecting said body to said draft tongue assembly for vertically adjusting said pick-up head.
Claim 2
Dependent Claim
226 words
In combination with a peanut combine or like machine having an elongate body provided with a crop pick-up head at its forward end which requires drive from the power take-off of an associated tractor, support wheels for the body to allow the pick-up head to be adjusted in a vertical plane about the axis of the support wheels; a draft tongue assembly projecting forwardly from said body and adapted to be connected to the associated tractor in such fashion as allows substantially no movement between the draft tongue assembly and the associated tractor in a vertical plane; pivot connections means between said draft tongue assembly and said body for establishing a horizontal transverse pivot axis connection therebetween to allow vertical movement of said pickup head about said axis of the support wheels; drive coupling means on said draft tongue assembly having an input shaft disposed at a selected height alignment with the power take-off of the associated tractor and having an output shaft coaxial with said transverse pivot axis between the draft tongue assembly and said body whereby vertical movement of said pick-up head has minimum effect on the height alignment of said input path nor does it affect the alignment of said output shaft relative to said body; and power means connecting said body to said draft tongue assembly for vertically adjusting said pick-up head.
Claim 3
Dependent Claim
57 words
In the combination as defined in claim 1 wherein said draft tongue assembly includes a transverse frame member at the rearward end thereof and vertical frame arms at the opposite ends of said transverse frame member, said drive coupling means being mounted on said transverse frame member with said output shaft thereof in parallel offset relation thereto.
Claim 4
Dependent Claim
35 words
In the combination as defined in claim 2 including sensing means carried by said pick-up head for controlling said power means to maintain said pick-up head substantially at a selected level above the ground surface.
Claim 5
Dependent Claim
35 words
In the combination as defined in claim 1 including sensing means carried by said pick-up head for controlling said power means to maintain said pick-up head substantially at a selected level above the ground surface.
Claim 6
Dependent Claim
118 words
In the combination as defined in claim 1 wherein said body includes a pair of spaced, parallel, fore-and-aft extending frame plates at the forward end thereof; said draft tongue assembly including a transverse frame member at the rearward end thereof disposed between said frame plates, vertical frame arms connected to the opposite ends of said frame member in closely spaced relation to respective ones of said frame plates; said pivot connection means being in the form of hollow bearing means interconnecting said frame plates and said frame arms in offset relation to said transverse frame member; said output shaft of the drive coupling means extending through one hollow bearing means to terminate outboard of the corresponding frame plate.
Claim 7
Dependent Claim
35 words
In the combination as defined in claim 5 including Sensing means carried by said pick-up head for controlling said power means to maintain said pick-up head substantially at a selected level above the ground surface.
Claim 8
Dependent Claim
133 words
In the combination as defined in claim 1 wherein said body includes a pair of spaced, parallel, fore-and-aft extending frame plates at the forward end thereof; said draft tongue assembly including a transverse frame member at the rearward end thereof disposed between said frame plates, vertical frame arms connected to the opposite ends of said frame member in closely spaced relation to respective ones of said frame plates; said pivot connection means being in the form of hollow bearing means interconnecting said frame plates and said frame arms in offset relation to said transverse frame member; said output shaft of the drive coupling means extending through one hollow bearing means to terminate outboard of the corresponding frame plate; said power means being connected to said frame arms remote from said hollow bearing means.
