Abstract
Abstract An inclined grain auger conveyor provided with first and second upper and lower vertically registered auger assemblies. Both of the auger assemblies include sections therein wherein the auger screw is provided with circumferentially spaced and longitudinally extending bars and the housing portion includes removable grate sections in lieu of the more conventional screening sections which generally extend substantially the full length of each auger conveyor outer housing. The forward end of the auger conveyor is provided with an auger extension for disposition in a pile of grain and to convey grain to the lower end of the grain cleaning portion of the auger assembly. In order to mount the cylindrical bars on the auger screw portions of the auger assemblies adjacent flutes of the auger screw are provided with sets of longitudinally spaced and aligned notches spaced circumferentially about the auger screw and the cylindrical bars are secured within these notches. In each section of each auger assembly where the cylindrical bars are used, the usual screen portions of the housing of the auger assembly are replaced by grates wherein the grain auger and cleaner may not only clean but also thresh the cut grain being handled by the auger and cleaner.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
213 words
A grain auger conveyor including inclined upper and lower vertically spaced and registered elongated and generally parallel screw auger assemblies, each of said assemblies including a driven auger screw journaled in a casing, the lower periphery of the casing of the upper assembly including screening portions spaced therealong, the casing of said lower assembly opening upwardly toward the screening portions of the upper assembly, said lower casing also including screening portions spaced along the lower periphery thereof, said conveyor including an elongated shroud extending along and enclosing the outer, upper and lower sides of a zone disposed to one side of and extending along the areas defined between the assemblies and opening laterally into said area, a plurality of airflow regulating slides spaced along said assembly and supported therefrom for guided independent variable shifting laterally of the auger screw assemblies in a plane generally paralleling the plane containing said assemblies between closed side-by-side positions closing the side of said zone adjacent said area from the latter and at least partially open positions establishing at least partial direct communication between said zone and said area, means operative to supply air under pressure to said zone for variable lateral discharge therefrom into said area past said slides, the other side of said area being open.
Claim 2
Dependent Claim
213 words
A grain auger conveyor including inclined upper and lower vertically spaced and registered elongated and generally parallel screw auger assemblies, each of said assemblies including a driven auger screw journaled in a casing, the lower periphery of the casing of the upper assembly including screening portions spaced therealong, the casing of said lower assembly opening upwardly toward the screening portions of the upper assembly, said lower casing also including screening portions spaced along the lower periphery thereof, said conveyor including an elongated shroud extending along and enclosing the outer, upper and lower sides of a zone disposed to one side of and extending along the areas defined between the assemblies and opening laterally into said area, a plurality of airflow regulating slides spaced along said assembly and supported therefrom for guided independent variable shifting laterally of the auger screw assemblies in a plane generally paralleling the plane containing said assemblies between closed side-by-side positions closing the side of said zone adjacent said area from the latter and at least partially open positions establishing at least partial direct communication between said zone and said area, means operative to supply air under pressure to said zone for variable lateral discharge therefrom into said area past said slides, the other side of said area being open.
Claim 3
Dependent Claim
54 words
The combination of claim 1 wherein said conveyor further includes longitudinally extending air regulating plates supported therefrom on the side of said area remote from said zone and adjustably shiftable into and out of at least partial registry with said open side of said area for partial throttling of said discharged laterally outwardly therefrom.
Claim 4
Dependent Claim
50 words
The combination of claim 1 wherein the casings of said upper and lower screw auger assemblies include longitudinally spaced grate portions, the flutes of the auger screw of said assemblies registrable with said grate portions including circumferentially spaced longitudinally extending bars disposed about the outer peripheral portions of said flutes.
Claim 5
Dependent Claim
20 words
The combination of claim 3 wherein said flutes are notched and seatingly receive the adjacent portions of said bars therein.
Claim 6
Dependent Claim
10 words
The combination of claim 4 wherein said bars are cylindrical.
Claim 7
Dependent Claim
38 words
The combination of claim 5 including means supporting said grates and said screening portions from said casings for adjustable shifting of said grates and screening portions generally radially of the axes of rotation of the corresponding auger screws.
Claim 8
Dependent Claim
17 words
The combination of claim 6 wherein the radial outermost edge portions of said flutes are transversely enlarged.
Claim 9
Dependent Claim
118 words
A grain auger conveyor including inclined upper and lower vertically spaced and registered elongated and generally parallel screw auger assemblies, each of said assemblies including a driven auger screw journaled in a casing, the lower periphery of the casing of the upper assembly including screening portions spaced therealong, the casing of said lower assembly opening upwardly toward the screening portions of the upper assembly, said lower casing also including screening portions spaced along the lower periphery thereof, the casings of said upper and lower auger screw assemblies including longitudinally spaced grate portions, the flutes of the auger screws of said assemblies registrable with said grate portions including circumferentially spaced outer peripheral bars extending longitudinally of said auger screws.
Claim 10
Dependent Claim
118 words
A grain auger conveyor including inclined upper and lower vertically spaced and registered elongated and generally parallel screw auger assemblies, each of said assemblies including a driven auger screw journaled in a casing, the lower periphery of the casing of the upper assembly including screening portions spaced therealong, the casing of said lower assembly opening upwardly toward the screening portions of the upper assembly, said lower casing also including screening portions spaced along the lower periphery thereof, the casings of said upper and lower auger screw assemblies including longitudinally spaced grate portions, the flutes of the auger screws of said assemblies registrable with said grate portions including circumferentially spaced outer peripheral bars extending longitudinally of said auger screws.
Claim 11
Dependent Claim
20 words
The combination of claim 8 wherein said flutes are notched and seatingly receive the adjacent portions of said bars therein.
Claim 12
Dependent Claim
10 words
The combination of claim 9 wherein said bars are cylindrical.
Claim 13
Dependent Claim
40 words
The combinAtion of claim 8 including means supporting said grate portions and said screening portions from said casings for adjustable shifting of said grate portions and screening portions generally radially of the axes of rotation of the corresponding auger screws.
Claim 14
Dependent Claim
52 words
The combination of claim 8 wherein the outer peripheral edges of the flutes of the auger screws of said assemblies include transversely enlarged head portions whose outer surfaces are corrugated so as to function more thoroughly in threshing the grain between the head portions and the grating bars of the corresponding grates.
