Abstract
Abstract A hopper for use with grain elevators is the subject of the present invention. Two components are separable but are held together by a friction coupling. The first component comprises a trough which partially encloses the auger and receives the second component which presents a hopper for receiving grain. The holding area of the hopper empties into an opening which is in alignment with the open area of the auger for feeding grain to the latter. A pair of side flaps extend from the holding area down into the trough to present a coupling to hold the two components together.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
A hopper for use with a grain auger comprising: trough means partially enclosing said auger, said trough means presenting an opening for receiving said auger and having a cross-sectional dimension equal to the diameter of said auger plus sufficient clearance to accomodate turning of the auger therein; means for defining a holding area for a quantity of grain, said holding area being disposed above said auger; means for presenting an opening in said holding area of a width corresponding to the width of said trough opening; and opposed side flaps extending downwardly from said holding area defining means into said trough means and on either side of said auger for coupling said holding area defining means with said trough means.
Claim 2
Dependent Claim
120 words
A hopper for use with a grain auger comprising: trough means partially enclosing said auger, said trough means presenting an opening for receiving said auger and having a cross-sectional dimension equal to the diameter of said auger plus sufficient clearance to accomodate turning of the auger therein; means for defining a holding area for a quantity of grain, said holding area being disposed above said auger; means for presenting an opening in said holding area of a width corresponding to the width of said trough opening; and opposed side flaps extending downwardly from said holding area defining means into said trough means and on either side of said auger for coupling said holding area defining means with said trough means.
Claim 3
Dependent Claim
30 words
The invention of claim 1, wherein said trough means comprises a first separable component and said holding area defining means together with said coupling means comprises a second separable component.
Claim 4
Dependent Claim
31 words
The invention of claim 2, wherein is included support means coupled with said trough means for holding the latter at an angle corresponding to the angle of disposition of said auger.
Claim 5
Dependent Claim
116 words
A hopper for use with a grain auger comprising: a first separable component comprising: trough means partially enclosing said auger, said trough means presenting an elongated opening for receiving an auger; and a second separable component comprising: (a) means for defining a holding area for a quantity of grains disposed above said grain auger, (b) means presenting an opening in said holding area of a width corresponding to the width of said trough opening, and (c) means for coupling said holding area defining means with said trough means, said coupling means consisting only of opposed side flaps extending downwardly from said holding area defining means into said trough means and on either side of said auger.
Claim 6
Dependent Claim
116 words
A hopper for use with a grain auger comprising: a first separable component comprising: trough means partially enclosing said auger, said trough means presenting an elongated opening for receiving an auger; and a second separable component comprising: (a) means for defining a holding area for a quantity of grains disposed above said grain auger, (b) means presenting an opening in said holding area of a width corresponding to the width of said trough opening, and (c) means for coupling said holding area defining means with said trough means, said coupling means consisting only of opposed side flaps extending downwardly from said holding area defining means into said trough means and on either side of said auger.
