Abstract
Abstract A portable grain bin has a V-shaped botton with right and left hand augers to move the grain to the center of the grain bin where an auger elevator lifts it to be discharged into a truck. A perforated tube immediately above the augers in the bottom of the storage bin is connected to a fan on the storage bin so that dry air may be blown into the grain to dry the grain and keep it from heating. Wheels on the bin permit the bin to be moved from one field to an adjacent field, although when in use, the bin rests upon runners.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
A structure for grain storage comprising: (a) a bin having a length several times the width, (b) said bin supported by runners extending along the length thereof, (c) said bin having a V-shaped bottom across the width, (d) an elevator extending from the V-shaped bottom at about the midpoint of the length, (e) a rear conveyor extending from the rear of the bin to the elevator, (f) a front conveyor extending from the front of the bin to the elevator, (g) elevator drive means attached to the elevator for driving same, (h) elevator activating means attached to the elevator drive means for activating same, (j) front conveyor drive means attached to the front conveyor for driving same, (k) front conveyor activating means attached to the front conveyor drive means for activating same, (m) rear conveyor drive means attached to the rear conveyor for driving same, and (n) rear conveyor activating means attached to the rear conveyor drive means for activating same.

Claim 3
Dependent Claim
63 words
The invention as defined in claim 1 with additional limitations of (o) a perforated tube running the length of the bin (p) within the bin immediately above said front and back conveyors, (q) a fan outside the bin, (r) the fan connected to the perforated tube so that dry air may be blown through the tube and its perforations and through the grain.
Claim 4
Dependent Claim
62 words
The invention as defined in claim 1 with additional limitations of (o) a plurality of wheels, (p) means attaching the wheels to said runners for raising and lowering the wheels whereby said runners may be raised above the ground, (g) a hitch on one end of the structure whereby the structure may be attached to a vehicle and towed by the vehicle.
Claim 5
Dependent Claim
162 words
The invention as defined in claim 1 with additional limitations of (o) a drive shaft extending below the bin from the front of the bin to at least the elevator, (p) said drive shaft drivingly connected to the elevator, thus forming a portion of said means for driving said elevator, (q) a tumble shaft, (r) said tumble shaft being adapted to be attached to a source of power to furnish power to the elevator and conveyors, (s) an elevator clutch, (t) said elevator clutch operatively connecting the elevator and the drive shaft, (u) said elevator clutch forming a portion of said actuating means for activating the drive means for the elevator, (v) a front clutch interconnecting said main drive shaft and said front conveyor drive means, thus forming a portion of said front conveyor actuating means, and (w) a rear clutch interconnecting said main drive shaft and said rear conveyor drive means, thus forming a portion of said rear conveyor activating means.
Claim 6
Dependent Claim
63 words
The invention as defined in claim 4 wherein additional limitations of (x) a perforated tube running the length of the bin (y) within the bin immediately above said front and back conveyors, (z) a fan outside the bin, (aa) the fan connected to the perforated tube so that dry air may be blown through the tube and its perforations and through the grain.
Claim 7
Dependent Claim
23 words
The invention as defined in claim 4 with an additional limitation of (x) each of said clutches being controlled by an electric clutch.
Claim 8
Dependent Claim
68 words
The invention as defined in claim 6 with additional limitations of (y) a platform on the outside of said bin within about 1.7 meters of the top of said bin so that a person standing on said platform may see the inside of the bin, and (z) switches electrically connected to said electric clutches attached to said bin adjacent said platform so that they may be operated therefrom.
Claim 9
Dependent Claim
63 words
The invention as defined in claim 7 with additional limitations of (aa) a perforated tube running the length of the bin (bb) within the bin immediately above said front and back conveyors, (cc) a fan outside the bin, (dd) the fan connected to the perforated tube so that dry air may be blown through the tube and its perforations and through the grain.
Claim 10
Dependent Claim
62 words
The invention as defined in claim 8 with additional limitations of (ee) a plurality of wheels, (ff) means attaching the wheels to said runners for raising and lowering the wheels whereby said runners may be raised above the ground, (gg) a hitch on one end of the structure whereby the structure may be attached to a vehicle and towed by the vehicle.
