| Number | Title | Issue Date |
| 4653515 | Self-propelled harvester thresher A self-propelled harvester thresher has a threshing mechanism operating in accordance with a radial flow, a separating mechanism operating in accordance with an axial flow, and a transfer drum located between the threshing mechanism and the separating mec... | 03/31/1987 |
| 4611605 | Axial flow rotary separator In the axial flow rotary separator of a combine harvester spiral propulsion of the crop material mat is achieved through the cooperation of helical guide vanes in the separator casing and rotor fingers free to swing axially. The rotor is eccentrically mou... | 09/16/1986 |
| 4611606 | Feeding arrangement for an axial flow rotary separator The axial flow rotary separator of a self-propelled combine employs dual side-by-side rotors sharing a common infeed opening. Finger-like crop engaging elements of the rotors are propelled in orbits both oblique and eccentric with respect to the separator... | 09/16/1986 |
| 4574815 | Rotor for an axial flow rotary separator In an axial flow rotary separator, each radially extending finger-like crop-engaging element of the rotor is individually and obliquely journaled on a fixed eccentric shaft. Push bars spaced 90 degrees apart rotate about the axis of the separator to drive... | 03/11/1986 |
| 4408618 | Axial flow rotary separator In a combine harvester axial flow rotary separator, crop material is propelled in a generally spiral path as a relatively thin mat, maintained in contact with the inner wall of a cylindrical separator housing due to centrifugal force from the motion impar... | 10/11/1983 |
| 4373536 | Mobile corn harvester A mobile corn harvester comprises a chassis on which is mounted an upwardly and rearwardly inclined casing. The forward end of the casing is formed as a hopper into which fall corn stalks cut by cutters at the front of the casing. A rotor rotatable in the... | 02/15/1983 |
| 4284086 | Threshing and separating apparatus A threshing unit is arranged in a concentrically spaced relation within a perforated rotatable grain separating cylinder. An elongated axially fluted impeller located below the threshing unit and within the separating cylinder accelerates the speed of tra... | 08/18/1981 |
| 4208858 | Isolated pneumatic cleaning system In a harvesting and threshing machine utilizing at least one cooperative cylinder and rotatable rotor to achieve axial flow threshing and separation of grain bearing crop material there is provided an improved grain collection means underlying the auxilia... | 06/24/1980 |
| 4198802 | Axial flow rotary separator for a combine In a rotary separator, cylindrical threshing, frusto-conical separating, and centrifugal fan sections are arranged coaxially and in tandem. A fixed grate including threshing and separating portions surrounds and generally conforms to a rotor profile. A fr... | 04/22/1980 |
| 4178942 | Apparatus for agricultural machines An apparatus is provided for receiving, separating, distributing, and conveying mixture of materials, such as a mixture of grain, straw and chaff, in a manner that separates small particles of one kind, such as grain, from the rest of the mixture. Inner a... | 12/18/1979 |
| 4178943 | Rotor for an axial flow rotary separator Material control elements carried by the rotor of an axial flow rotary combine separator include inclined blades as well as conventional rasp bars. The inclined blades take various forms but common features include their downstream inclination, (that is i... | 12/18/1979 |
| 4149360 | Axial thresher and straw walker means for combine A combine harvester having crop cutting and elevating means at the forward end of the combine to deliver crop material to be threshed to a threshing compartment in which axial rotor and concave means thresh and axially move the crop material to straw walk... | 04/17/1979 |
| 4087953 | Combine crop feeding system A combine has a feeding system, for conveying crop material from a harvesting unit to the infeed rotor of a longitudinal axial flow rotary crop processing unit, including a feeder house employing a pair of augers, mounted side by side in an enclosed housi... | 05/09/1978 |
| 4075823 | Combine harvester A combine harvester comprising two side-by-side generally cylindrical crop handling units each having tandem threshing and separating sections. A conveyor is provided for receiving crop material from a forwardly positioned crop header and delivering it ax... | 02/28/1978 |
