Abstract
Abstract A baler is comprised of a plurality of rollers and two sets of belts supported on the roller and defining a bale-forming chamber for rolling crop material into a cylindrical bale. A guide is mounted on the exterior of the bale-forming chamber and generally parallel to its longitudinal axis. A control wheel is mounted on a support means for mounting the wheel on the guide for movement about an axis perpendicular to the longitudinal axis of the chamber. By movement of the guide, the control wheel may be moved into and out of contact with one set of the belts. The support further carries a twine guide for guiding the entry of twine into the bale-forming chamber during movement of the support to and fro along the transverse guide. The movement of the wheel about the axis perpendicular to the longitudinal axis of the chamber controls the direction of displacement of the support along the guide when the control wheel is engaged with the set of belts.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
134 words
In a binding device for a baler comprising a plurality of rollers and two sets of flexible members supported on said rollers and defining a bale-forming chamber for rolling up harvested products into a cylindrical bale, the improvement comprising: a guide extending generally parallel to the longitudinal axis of said chamber; a rotatable control wheel; twine feeding means for holding said twine and responsive to the rotation of said control wheel, feeding twine toward a bale in said chamber; a support means for mounting said wheel, said feeding means and said guide on said baler (1) for movement of said wheel about an axis perpendicular to the longitudinal axis of said chamber (2) for movement of said wheel into and out of engagement with one of said sets and (3) for guiding said twine.
Claim 2
Dependent Claim
134 words
In a binding device for a baler comprising a plurality of rollers and two sets of flexible members supported on said rollers and defining a bale-forming chamber for rolling up harvested products into a cylindrical bale, the improvement comprising: a guide extending generally parallel to the longitudinal axis of said chamber; a rotatable control wheel; twine feeding means for holding said twine and responsive to the rotation of said control wheel, feeding twine toward a bale in said chamber; a support means for mounting said wheel, said feeding means and said guide on said baler (1) for movement of said wheel about an axis perpendicular to the longitudinal axis of said chamber (2) for movement of said wheel into and out of engagement with one of said sets and (3) for guiding said twine.
Claim 3
Dependent Claim
15 words
The device of claim 1, wherein said support means is slidably mounted on the guide.
Claim 4
Dependent Claim
37 words
The device of claim 2 wherein said support means includes a bracket slidably mounted on said guide and a wheel cover pivotably mounted on said bracket for movement about said perpendicular axis and rotatably mounting said wheel.
Claim 5
Dependent Claim
29 words
The device of claim 3, further comprising stop means for limiting and defining the angular position of the control wheel with respect to the longitudinal axis of the baler.
Claim 6
Dependent Claim
37 words
The device of claim 4, wherein said support means further comprises an over-center tension spring connected between said cover and said bracket for maintaining the control wheel alternatively in each of two positions about said perpendicular axis.
Claim 7
Independent Claim
41 words
The device of any one of claims 1-4 or 5 further comprising means for reversing the orientation of the control wheel about said perpendicular axis when the control wheel reaches the end of its travel adjacent one end of said chamber.
Claim 8
Dependent Claim
36 words
The device of claim 6, further comprising a rope connected to said support means for reversing the orientation of said wheel about said perpendicular axis and for disengaging said wheel from said one set of members.
Claim 9
Independent Claim
50 words
The device of any one of claims 1-4 or 5: wherein said feeding means comprises a pressure wheel for pressing said twine against said control wheel and further comprising means for permitting rotation of said control wheel only in a direction corresponding to the entry of twine into said chamber.
Claim 10
Independent Claim
30 words
The device of any one of claims 1-4 or 5 further comprising means for locking said control wheel in a position out of contact with said one set of members.
Claim 11
Dependent Claim
50 words
The device of claim 9, wherein said guide has a noncircular cross section and is mounted on said baler to pivot about its axis, and said locking means locks said guide in a position corresponding to the position of the control wheel when disengaged from said one set of members.
Claim 12
Dependent Claim
32 words
The device of claim 10 further comprising a knife mounted on said support means for engaging and severing said twine when said control wheel is disengaged from said one set of members.
