Abstract
Abstract A machine for forming large round bales of hay and the like has a pickup mechanism that removes the crop from the field and delivers it rearwardly between a pair of compresser rolls, which deliver crop material in a mat to a baling zone between upper and lower endless conveyors. The upper conveyor includes a plurality of endless belts trained around a plurality of transverse rollers, one of which is disposed adjacent the rearward end of the lower conveyor and is mounted on a rear gate assembly that is swingable upward and rearwardly to permit discharge of the bale from the baling chamber. As the bale increases in size, its center of gravity moves rearwardly and after its initial stage of formation, it is partially supported on the roller adjacent the lower conveyor, said roller being disposed generally below the center of the bale when the bale reaches full size. An auxiliary roller is provided on the rear gate assembly immediately adjacent to said main bale support roller to help support the underside of the bale and thereby reduce the penetration of the roller into the periphery of the bale, the auxiliary supporting roller being vertically adjustable relative to the main support roller to selectively vary the amount of load carried by the main support roller and thereby selectively vary the rolling resistance caused by the penetration of the main support roller into the bale periphery.

Claim 1
Independent Claim
289 words
In a machine for forming cylindrical bales of crop material and having a mobile frame including a shiftable gate assembly and opposite upright sides forming a baling chamber therebetween, a plurality of transverse rollers including a first roller carried by the gate assembly and a second roller spaced forwardly of the first roller, an endless belt means trained around the rollers and having a lower forwardly moving bale engaging run in the baling chamber between the first and second rollers, crop delivery means for removing crop material from the ground and delivering it to the baling chamber so that it is engaged by the bale engaging run of the belt means and rolled in spiral fashion into a cylindrical bale with the first roller disposed below and at least partially supporting the weight of the bale at least in the latter stages of its formation, the improvement comprising: an auxiliary roller; and adjustable mounting means rotatably supporting the auxiliary roller on the rear gate assembly parallel and rearwardly proximate to the first roller for adjustment of the auxiliary roller between an upper position, wherein the top of the roller is at approximately the same level as the first roller and substantially helps to support the bale, and a lower position, wherein the top of the roller is substantially below the level of the top of the first roller and provides a lesser amount of support for the bale, the auxiliary roller being spaced in a fore and aft direction from the roller a distance than less twice the diameter of the first roller and being disposed so that the auxiliary roller supports a portion of the weight of the bale at least in the latter stages of bale formation.

In a machine for forming cylindrical bales of crop material and having a mobile frame including a shiftable gate assembly and opposite upright sides forming a baling chamber therebetween, a plurality of transverse rollers including a first roller carried by the gate assembly and a second roller spaced forwardly of the first roller, an endless belt means trained around the rollers and having a lower forwardly moving bale engaging run in the baling chamber between the first and second rollers, crop delivery means for removing crop material from the ground and delivering it to the baling chamber so that it is engaged by the bale engaging run of the belt means and rolled in spiral fashion into a cylindrical bale with the first roller disposed below and at least partially supporting the weight of the bale at least in the latter stages of its formation, the improvement comprising: an auxiliary roller; and adjustable mounting means rotatably supporting the auxiliary roller on the rear gate assembly parallel and rearwardly proximate to the first roller for adjustment of the auxiliary roller between an upper position, wherein the top of the roller is at approximately the same level as the first roller and substantially helps to support the bale, and a lower position, wherein the top of the roller is substantially below the level of the top of the first roller and provides a lesser amount of support for the bale, the auxiliary roller being spaced in a fore and aft direction from the roller a distance than less twice the diameter of the first roller and being disposed so that the auxiliary roller supports a portion of the weight of the bale at least in the latter stages of bale formation.
Claim 3
Dependent Claim
262 words
In a machine for forming cylindrical bales of crop material and having a mobile frame including a rear gate assembly shiftable between a raised bale discharge position and a lowered baling position, a baling chamber, means for removing crop material from the ground and delivering it to the baling chamber, and conveyor means defining the periphery of the baling chamber and adapted to receive crop material from the crop delivery means and roll it into a spiral cylindrical bale, the conveyor means including a first support roller rotatably carried by the rear gate assembly axially parallel to the bale axis and adapted to at least partially support the underside of a bale in the baling chamber at least after it reaches a predetermined size, the improvement comprising: an auxiliary roller; an adjustable support means rotatably mounting the auxiliary roller on the rear gate assembly adjacent and parallel to the first support roller generally below the axis of a fully formed bale for adjustment between a first position, wherein it also partially supports the underside of a bale in the baling chamber at least after it reaches a predetermined size, and a second position, wherein it is disposed away from the bale axis a greater distance than the first support roller and provides a lesser amount of support for the bale, the auxiliary roller having its top surface at generally the same level as the top surface of the first support roller in its first position and below the level of the top surface of the first support roller in its second position.
