Abstract
Abstract In a grain drying bin, drying conduit members are attached to the inside wall and extend to and rest on the foundation to supportively reinforce the bin wall and thereby permit use of lighter gauge wall panels, while also serving the air distribution function of such conduits.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
199 words
In a grain bin having a foundation including a bottom floor, a noninsulated wall supported on said foundation, a perforated subfloor spaced above said bottom floor and forming a chamber between said floors, and means for forcing dry air into said chamber; means for preventing condensation from forming on the interior surface of said wall and for reinforcing said wall comprising: a plurality of upright rigid hollow conduit members positioned about the interior of the bin wall in arcuately spaced relation to one another; each of said conduit members resting at its lower end on said foundation; means providing fluid communication between the hollow interior of each of said conduit members and said chamber when said conduit members are resting on said foundation; each of said conduit members having a closed upper end; each of said conduit members having a plurality of spaced air diffusing perforations formed therein, a predetermined number of which direct air flow laterally along said bin wall; and said conduit members being secured in reinforcing relation to the interior of said bin walls and with said lower ends resting on said foundation whereby said conduit members provide reinforcement and load bearing support for said wall.
Claim 2
Dependent Claim
199 words
In a grain bin having a foundation including a bottom floor, a noninsulated wall supported on said foundation, a perforated subfloor spaced above said bottom floor and forming a chamber between said floors, and means for forcing dry air into said chamber; means for preventing condensation from forming on the interior surface of said wall and for reinforcing said wall comprising: a plurality of upright rigid hollow conduit members positioned about the interior of the bin wall in arcuately spaced relation to one another; each of said conduit members resting at its lower end on said foundation; means providing fluid communication between the hollow interior of each of said conduit members and said chamber when said conduit members are resting on said foundation; each of said conduit members having a closed upper end; each of said conduit members having a plurality of spaced air diffusing perforations formed therein, a predetermined number of which direct air flow laterally along said bin wall; and said conduit members being secured in reinforcing relation to the interior of said bin walls and with said lower ends resting on said foundation whereby said conduit members provide reinforcement and load bearing support for said wall.
Claim 3
Dependent Claim
21 words
The bin of claim 1 wherein said conduit members extend over a substantial portion of the height of said bin wall.
Claim 4
Dependent Claim
19 words
The bin of claim 2 wherein said conduit members are symmetrically arranged about the interior of said bin wall.
Claim 5
Dependent Claim
19 words
The bin of claim 1 wherein each of said conduit members has a plurality of angularly disposed planar surfaces.
Claim 6
Dependent Claim
44 words
The bin of claim 1 wherein said bin is formed of a plurality of rings of panels, said conduit members spanning at least the lower rings thereof, and means securing each of said conduit members to each of the lower rings of said wall.
Claim 7
Dependent Claim
45 words
The bin of claim 1 wherein said bin is formed of a plurality of rings of panels, said conduit members spanning at least the lower rings thereof, and means securing each of said conduit members to said wall at each adjacent junction between said rings.
Claim 8
Dependent Claim
129 words
A grain drying and bin support system for grain bins having a foundation, a bottom floor, a wall supported on said foundation, and a perforate sub-floor spaced above said bottom floor and delimiting a chamber therebetween, comprising a plurality of hollow conduit members extending vertically along the sidewall interior and secured to said sidewall in abutting relation with said foundation, each of said conduit members having a plurality of spaced air diffusing perforations formed therein and each provided with an access opening within said chamber to assure fluid communication between said chamber and the hollow conduit interior, whereby structural support for the bin wall is provided by the secured floor abutting conduits while effective grain drying is assured by the access opening and plurality of perforations in said conduits.
Claim 9
Dependent Claim
129 words
A grain drying and bin support system for grain bins having a foundation, a bottom floor, a wall supported on said foundation, and a perforate sub-floor spaced above said bottom floor and delimiting a chamber therebetween, comprising a plurality of hollow conduit members extending vertically along the sidewall interior and secured to said sidewall in abutting relation with said foundation, each of said conduit members having a plurality of spaced air diffusing perforations formed therein and each provided with an access opening within said chamber to assure fluid communication between said chamber and the hollow conduit interior, whereby structural support for the bin wall is provided by the secured floor abutting conduits while effective grain drying is assured by the access opening and plurality of perforations in said conduits.
Claim 10
Dependent Claim
21 words
The system of claim 7 wherein said conduit members extend over a substantial portion of the height of said bin sidewall.
Claim 11
Dependent Claim
44 words
The bin of claim 7 wherein said bin is formed of a plurality of rings of panels, said conduit members spanning at least the lower rings thereof, and means securing each of said conduit members to each of the lower rings of said wall.
