Patent number: 6053811Abstract: An apparatus for use in combination with a combine for sensing the volume of tailings exhausted from a cleaning section of the combine and for providing a visual indication to the operator of the effectiveness of combine operation. The combine includes a mobile frame or chassis having an operator compartment arranged toward a forward end thereof. A threshing section of the combine separates grain from crop material delivered thereto. A cleaning section of the combine functions to remove chaff and tailings from the materials received from the threshing section. A tailings section of the combine is arranged to receive incompletely threshed and separated tailings from the cleaning section. The tailings section comprises a tailings conveyor for forcibly moving tailings toward an elevator that moves the tailings to one of the other sections on the combine for recycling.Type: GrantFiled: October 10, 1996Date of Patent: April 25, 2000Assignee: Case CorporationInventors: Orlin W.

Patent number: 5911673Abstract: An improved row crop header for harvesting crops planted in rows. The improved row crop header has a plurality of row units mounted on a frame such that each row unit has at least one gatherer operating in a gatherer plane that is oblique to a row unit plane that passes through the structure of the row unit. The reduced projected width of the gatherer along the row unit plane reduces the width of a row unit. The adjacent gatherers of two adjacent row units overlap as they operate in offset planes. The overlap permits the row units to be arranged closer together on the frame. The closer arrangement together with the reduced width of the row units allows the row crop header to harvest narrower crop rows than the existing corn heads. A method is also provided that uses the improved row crop header to harvest narrower crop rows than in the past.Type: GrantFiled: December 13, 1996Date of Patent: June 15, 1999Assignee: Case CorporationInventor: Orlin W. Johnson

Patent number: 4660360Abstract: A cutterbar assembly for the header of an agricultural combine having a skid coextensive with the cutterbar but comprising individual skid segments. The knife guard likewise comprises individual segments positioned in aligned relationship with the skid segments, whereby the flexibility of the cutterbar is enhanced so that it is able to follow the contour of the ground without row sensitivity. The skid segments are corrugated to provide a more efficient strength to weight ratio.Type: GrantFiled: October 15, 1985Date of Patent: April 28, 1987Assignee: J. I. Case CompanyInventors: Richard A. Hardesty, Dathan R. Kerber, Orlin W. Johnson, Richard E. Benson

Patent number: 4622805Abstract: A header frame for a combine harvester having a linkage connection between the crop reel and the auger, whereby the auger may be automatically and mechanically raised from the header floor by raising the reel for purposes of unplugging wedged crop material. The linkage includes a lost-motion connection so that the reel can be moved vertically as required during harvesting without affecting the auger, and the auger is also capable of floating action during operation. A sprocket and chain drive for the auger includes a spring-biased idler sprocket for maintaining proper chain tension and uninterrupted operation of the auger at all times. An adjustable wedge is also provided for fixing and limiting the minimum spacing between the auger and the header floor.Type: GrantFiled: July 24, 1985Date of Patent: November 18, 1986Assignee: J. I. Case CompanyInventors: Orlin W. Johnson, Michael P. Larson, Richard E. Benson, Dathan R. Kerber, Jon R. Cross

Patent number: 4599852Abstract: A header for a combine or the like having a cutterbar assembly which is vertically flexible relative to the main frame of the header. Leaf springs are fixedly connected to the header frame and extend forwardly to a sliding connection with the cutterbar assembly to exert a counterbalancing upward force thereon. Longitudinally reciprocable adjustment bars captive on threaded adjustment bolts are mounted on the main frame in association with each spring for varying the upward force being exerted thereby.Type: GrantFiled: July 24, 1985Date of Patent: July 15, 1986Assignee: J. I. Case CompanyInventors: Dathan R. Kerber, Orlin W. Johnson, Richard E. Benson

Patent number: 4227363Abstract: A crop harvesting header for a self-propelled combine. The header includes a "floating" flexible cutterbar movable vertically relative to the header frame to cut a standing crop (soybeans, for example) close to the ground to minimize crop losses. The cutterbar is connected to a plurality of runner structures pivotally mounted on the header frame. A spring system is operative on the runner structures to resiliently counterbalance the cutterbar. Elongated skids are connected between adjacent pairs of runners to effectively extend along the length of the header. The skids are mounted to permit individual movement of the runners relative to each other as the cutterbar flexes over uneven ground across the harvesting path. The skids are selectively shiftable to vary the cutting height of the cutterbar.The combine includes a hydraulic system for raising and lowering the header. An automatic system raises and lowers the header in response to sensing the position of the cutterbar relative to the header.Type: GrantFiled: September 1, 1978Date of Patent: October 14, 1980Assignee: International Harvester CompanyInventors: Dathan R. Kerber, Orlin W. Johnson, Robert D. Week, Richard E. Benson, John L. VandeWiele, James R. Lucas

Patent number: 4206583Abstract: A crop harvesting header for a self-propelled combine. The header includes a "floating" cutterbar which is flexible and movable up and down so as to cut a standing crop (soybeans, for example) close to the ground to minimize crop losses. The flexibility and movement enable the crop to be cut closely to the ground even though the ground is uneven or undulating across and along the harvesting path. The cutterbar is mounted on a plurality of ground-engaging structures including runners upon which a counterbalancing system imposes pre-selected forces to control the ground pressure of the cutterbar as ground and crop conditions vary. The counterbalancing system provides a substantially constant ground pressure throughout cutterbar movement. The effect of the system is to moderate or eliminate the variations which come from spring force changes.Type: GrantFiled: September 1, 1978Date of Patent: June 10, 1980Assignee: International Harvester CompanyInventors: Robert D. Week, Orlin W. Johnson, Dathan R. Kerber

The header includes a "floating" flexible cutterbar movable vertically relative to the header frame to cut a standing crop (soybeans, for example) close to the ground to minimize crop losses. The cutterbar is connected to a plurality of runner structures pivotally mounted on the header frame. A spring system is operative on the runner structures to resiliently counterbalance the cutterbar. Structure is adjustably operative on the runner structures to selectively limit the range of movement of the cutterbar or to lock it against movement. Elongated skids are connected between adjacent pairs of runners to effectively extend along the length of the header. The skids are mounted to permit individual movement of the runners relative to each other as the cutterbar flexes over uneven ground across the harvesting path. The skids are selectively shiftable by crank pins to vary the cutting height of the cutterbar.Type: GrantFiled: September 1, 1978Date of Patent: June 10, 1980Assignee: International Harvester CompanyInventors: Orlin W. Johnson, Dathan R. Kerber

Patent number: T104302Abstract: A crop cutting apparatus having an elongated cutterbar, a plurality of guards, and reciprocating knife disposed in the usual arrangement wherein cylindrical cup-like retainer members are mounted by the guard mounting bolts to the top side of the cutterbar. A hold down clip slips over the retainer members and has a rearward portion contacting the cutterbar, a medial portion displaced from the cutterbar, and a forward portion including a horizontal surface acting against the knife and a vertical surface acting against the front side of the knife back. A single tie down bolt disposed between the retainer cups adjustably hold the clip in position to resist upward movements of the knife assembly.Type: GrantFiled: July 26, 1982Date of Patent: June 5, 1984Inventors: Orlin W. Johnson, Richard E. Benson, Dathan R. Kerber
