GRAIN BIN.

Laissez.

Application filed May l5,

To all whom t may concern Be it known that l. ALLEN lV. JOHN- soN, a citizen of the United States, resident oi YAnoka, county of Anoka, State oit Minneseta, have` invented certain new and useful Ylmprovements in Grain Bins', oit which the following is a specification.

The object ot my invention is to provide a grain bin of concrete block construction,

l() divided interiorly into a series of triangular bins, so arranged that the lateral pressure of the grain will be transmitted to the outside walls of the bin, provision also being made for delivering the grain from the bins to a l5 chamber beneath them or to a wagon on the outside ot the structiue.

A further object is to provide a bin of inexpensive durable construction and one which will be lireprootl and easily accessible at the top or bottom.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims. n

ln the accompanying drawings forming part of this specification,

Figure l is a vertical sectional View through a grain bin embodying my invention.

Figure 2 is a horizontal sectional view on the line 2-2 oit Figure l,

Figure 3 is an elevation of the lower portion of the bin, showing the means for admission to the chamber beneath the bins,

Figure 't is a sectional view on the line i-Jl of Figure 3.

In the drawing, 2 represents a suitable toundation and 3 the lower walls olf the bin, composed preferably of concrete blocks laid one upon another in the usual way and provided with an interlocking joint lbetweentheir longitudinal abutting edges. These lower walls are carried a suitable distance above the ground line and support a slab 5 of concrete, suitably reinforced in any pretei-red manner and forming the tloor of the bin proper. The upper walls 6 of the bin formed in the same manner as the lower walls, rest upon the floor 5 and are carried to the desired height to form a circular bin which is closed at the top by a suitable roof 7 having a central opening 8 that is normally closed by a hinged cover 9. Through this opening access may be conveniently had to` the inside of the structure. The space within the upper wall 6 and above the tloor 5 is divided by partitions l0, 10a, 10b, and lOc.

1920. Serial No. 381,693.

These partitions extend across the I space above the floor 5, dividing it into a series of bins ll, each bin being` in the form et the sector of a circle, a portion oit the outer wall ot the structure forming one wall oit the bin and two oit the partitions 'forming the other walls. Each inner wall of a bin is laterally braced by the walls oit the other bins so that when a bin is filled with grain, the lateral thrust or pressure thereof will be transmitted through these partition walls to the curved outer walls or the structure and will be braced and supported thereby. The bins are provided with bars 12 at intervals having their ends embedded in the partition walls and forming steps :for ascending the rails of the bins or to enable a person to enter the opening in the root of the structure and descend to the bottom of any one of the bins. The floor ot each. bin is provided with a vertical discharge spout 13 leading to the chamber la beneath the bins and each spout is provided with a suitable valve 1.5 by means of which the iiow oi grain from the bins may be regulated. Access to this space beneath the bins is readily obtained through the door opening 16 in the lower walls of the structure.

l also prefer to provide inclined spouts 1T in the walls of the structure above the iioo-r 5 so that the material in the bins can be spouted out to a wagon box or other suitable receptacle, it desired, these spouts being equipped with suitable regulating valves 18. This structure is made in various sizes and in various ways the details of construction herein shown and described may be inodiiied and still be within the scope of my invention.

l claim as my invention:

l. A structure of the class described having a foundation and lower walls and a horizontal floor supported thereby above the lower portion of said walls forming a chamber in the base of the structure, the upper walls of said struct-ure encircling a-chamber adapted to receive grain, said grain chainber having vertical partitions extending from the walls to the center thereof and dividing the interior space into a series of triangular bins, said iloor ormin the bottom oit' said bins and said partition transmitting the lateral pressure of the grain in one bin to the outer walls of the structure, the floor of said bins having vertical olischarge spouts therein leading to the chamber beneath said floor and said chamber having a door in its wall for access thereto. and the outer walls of said bins near said loor having outwardly and downwardly inclined spouts communicating respectively with the bins :for delivering` the contents thereof outside the structure to a wagon or other receptacle.

2. A structure of the class described having a foundation and lower walls and a horizontal floor supported thereby above the lower portion ot' said walls torining;- a chain ber in the base olf the structure, the upper walls of said structure encircling a chamber adapted to receive `grain7 said grain chamber having` vertical partitions extending 'troni the walls to the center thereof and dividingv the interior space into a series oil triangular bins, said floor loriningr the bottoni ot said bins and said partition transmitting the lateral. pressure oi. the grain in one bin to the outer walls of the structure, the 'Hoor of said bins having vertical discharge spouts therein leading to the chamber beneath said floor and said chamber havinga door in its wall for access thereto, and the outer walls of said bins near said floor having outwardly and downwardly inclined spoiits communicating; respectively with the bins for delivering the contents thereof outside the structure to a wagon or other receptacle, bars mounted in said partitions in the angles between thein for ascending the bins on the inside and said structure having a roof and a central opening and cover therefor through which access may be had to said bars and bins.

3. A structure of the class described coniprising a cylindrical wall having a icounda tion, a flat horizontal floor supported by said wall and forming therewith a comparatively large chamber in the bottoni ot' the strncture, the upper portion of said wall having a. roof and a central opening` therein7 and a space between said roof and floor havinc :i series of diagonal partitions dividing;- it into a plurality of vertical triangular shaped. bins, said horizontal `floor having` spouts tor conductingthe contents of said bins to the chamber beneath said floor and the outer walls of said structure having spouts near said door for delivering the contents of said bin on the outside of said structure, said vertical partitions intersecting at the center of the structure and transmitting' the load in said bins laterally to the outer walls thereof.

In witness whereof, I have hereunto set niy hand this 4th day of May 1920.

ALLEN D. W. JOHNSON.
