Claim 1
Independent Claim
211 words
A portable adjustable angle auger apparatus for conveying bulk materials comprising: a conveyor duct having an end beveled to project at the bottom and recede at the top and a discharge end; a supply duct having an end beveled to project at the bottom and recede at the top and a supply intake end; a conveyor auger disposed within said conveyor duct; a supply auger disposed within said supply duct; means for coupling said supply auger to said conveyor auger so that said augers rotate together and the axes of said augers are pivotable relative to each other; means for connecting said conveyor duct and said supply duct at the projecting beveled ends such that each duct end diverges upwardly from a convergence point formed by the connected projecting ends so that the slope and discharge end height of said conveyor duct can be varied by pivoting said conveyor duct relative to said supply duct about said duct connecting means; and a movable flexible covering for said ducts at said convergence point, said auger coupling means disposed within said ducts and said duct connecting means while said apparatus is conveying bulk materials; wherein said movable flexible covering is displaceable from said convergence point so as to facilitate disassembly of said apparatus.

A portable adjustable angle auger apparatus for conveying bulk materials comprising: a conveyor duct having an end beveled to project at the bottom and recede at the top and a discharge end; a supply duct having an end beveled to project at the bottom and recede at the top and a supply intake end; a conveyor auger disposed within said conveyor duct; a supply auger disposed within said supply duct; means for coupling said supply auger to said conveyor auger so that said augers rotate together and the axes of said augers are pivotable relative to each other; means for connecting said conveyor duct and said supply duct at the projecting beveled ends such that each duct end diverges upwardly from a convergence point formed by the connected projecting ends so that the slope and discharge end height of said conveyor duct can be varied by pivoting said conveyor duct relative to said supply duct about said duct connecting means; and a movable flexible covering for said ducts at said convergence point, said auger coupling means disposed within said ducts and said duct connecting means while said apparatus is conveying bulk materials; wherein said movable flexible covering is displaceable from said convergence point so as to facilitate disassembly of said apparatus.
Claim 3
Dependent Claim
15 words
The apparatus as recited in claim 1, wherein said duct connecting means comprise a hinge.
Claim 4
Dependent Claim
27 words
The apparatus as recited in claim 1, further comprising a supply hopper coupled to said supply duct such that said supply auger extends into said supply hopper.
Claim 5
Dependent Claim
17 words
The apparatus as recited in claim 1, further comprising a transport hitch fastened to said conveyor duct.
Claim 6
Dependent Claim
44 words
The apparatus as recited in claim 3, wherein said supply auger is mounted within said supply hopper by means of a telescoping shaft disposed within said supply auger said telescoping section being rotatably mounted on a telescoping shaft bearing attached to said supply hopper.
Claim 7
Dependent Claim
16 words
The apparatus as recited in claim 1, wherein said auger coupling means comprise a single U-joint.
Claim 8
Dependent Claim
28 words
The apparatus as recited in claim 3, wherein said supply hopper has a rectangular configuration and is formed with an aperture to which said supply duct is joined.
Claim 9
Dependent Claim
76 words
The apparatus as recited in claim 2, wherein said hinge comprises a first stationary member attached underneath said projecting beveled end of said conveyor duct, a second stationary member attached underneath said projecting beveled end of said supply duct and an insertable pin for connecting said first and second stationary members, wherein said first and second stationary members are formed with complimentary projections which intermesh to define an aligned aperture into which said pin is inserted.
