IMPROVEMENT IN G-RAIN-S'IOREHOUSES.

The Schedule rei'en'ad to in these Letters Patent and making part of the same.

To all whom 'it may concern Be it known that I, GEORGE CLARK,- of the city of Buiialo, county of Erie, and State of New York, have invented certain new and useful Improvements in the "Construction of Graih-Storehouses, or elevator-building's"; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, making a part of this =speoification, in which- Figure I is a vertical section of ,the lower portion of a grain-bin.

Figure VI is a vertical section, showing a modification 'in the construction of the wall of the grain-bin,

' Figure VII isa cross-section of the binder, shown.

in Fig. VI.

Figure VIII isa cross-section of the corner-post used with the modification represented in Fig. VI.

Figure IX is a vertical section, showing another modification in the construction of the wall of the grain-bin.

, Figure X is a cross-sectionof a corner-post.

. The nature of this invention consists-'- First, in supporting the bins of a grain-storehouse upon hollow columns, placed centrally underneath the .hopper forming the bottom of each bin, in such manner that the grain may be discharged from the bin into the top of the hollow column, and thence carried Zofi' through an aperture upon one side thereof.

Second, in the combination, with said hollow supporting-column, of a cast-iron hopper, which is provided 7 with strengthening-ribs, and the upper edges of which are so constructed as to form a suitable support for the walls, or partitions, between the bins.

Third, in supporting'each bin of a grain-storehouse upon an iron column placed centrally underneath the hopper composing the bottom of the bin.

Letters of like name'and kind refer to like parts in each of the figures. I

In the accompanying drawings- A represents the hollow castiron column, upon which the grain-bins are supported.

It is provided with a discharge-spout projecting from one side thereof, as shown at B, and with a hopperplate, 0, for the purpose of guiding the grain as it passes down the hollow column from the top, into the said discharge-spout B.

. A vertical slide, or gate, b, may be used and operated by means of a lever, if, or other suitable device, for the purpose of opening or closing .the dischargespout B. l

D represents the hopper, which forms the bottom of the bin; and is made of cast or wrought-iron.

A sleeve, or circular flange, d, at its lower extremity, fits over the top of the column, in a manner to form a firm and secure connection of the two parts.

In lieu of the hollow column A, two or more solid columns may be used as a central support of grainbins, the discharge-spout B being made part of or connected to the hopper D, and the columns grouped around the same, and connected thereto in any convenient and practicable manner.

The under side of the hopper D is provided with a series of strengthening-ribs, d, which may be arranged radially, as shown by dotted lines in Fig. V, or in any other manner to insure sufficient strength to support any weight which may be placed upon it.

The upper edges of the hopper, which are rectangular, are provided with one or more projecting flanges In Fig. I, where a single-plank wall is represented, there is only one flange, and the planks are held between the flanges of the two contiguous hoppers. In Fig. VI, there are two flanges upon the edge of each hopper, on account of there being a double-plank wall;

' and in Fig. IX, which represents the old and wellknown manner of planking bin-walls, as applied to my improvement, only one flange is required, the same as in the single-plank wall.

E represents a rim, projecting downwardly from the topedges of the hopper. Each side of the rim of each hopper rests against the rim of the hopper next adjoining, and may be secured-thereto by means of bolts, which should be passed through slots made in the rims,

so as to allow for settling of the walls.

Upon the edges of these cast-iron hoppers, the walls of the bins are erected. .As above indicated, I contemplate building them up in three difi'erent ways:

The first, shown in Fig. I, shows the planks set upon end, edge to edge, the lower ends being held between the flanges 11 while the upper ends are secured by .means' of the horizontal binders, or .flanged sills, F.

Upon the top of these, a second tier of upright planks. is erected, and their upper ends again secured by a second line of binders, and so on until the required height of the bin is-reached. The binder used in this first mode of constructing the walls of the bins is shown like the first, but held by one common binder, a crosssection of which is shown in Fig. VII. This second mode of construction admits of a circulation of air between the separate walls of the contiguous bins, that portionofcthe binders which is located between the two walls being perfo'rated,'to extend the circulation of air through all the tiers, from top to bottom. The special advantage gained by this construction consists in preventing the grain in one bin from being spoiled by a lot of heated or unsound grain in the bin adjoining, which is liable to occur in single plank bins.

The third mode of construct'gig the walls is well known, and represented in Fig. IX. It consists of the planks being laid flat, one upon the other. The hinders, or sills, are, in this case, dispensed with entirely.

At the point where the walls of a group of bins intersect each other, as well as at the corners of the outside bins, east-iron posts G are erected in. sections extending from thebottom to the top of the bins. These posts are proyided with longitudinal flanges, or ribs, between which the planks composing the walls are titted. The shape of these posts must, of course, depend upon the shape and construction of the walls. Figs. IV, VIII, and X, represent cross-sections of the posts used in the three difierent modes of construction of the walls, shown in Figs. I, VI, and IX, respectively. I

in order to give additional strength to the structure, either kind of walls, but more especially the doubleplank wall, may be provided with vertical or horizontal tie-rods, or both. They are represented by red lines in Figs. VI, VII, and VIII.

The object of this invention is to render grain-stores houses and elevator-buildings comparatively fire-proof at a less expense than has ever been done heretofore.

The first story of the building consisting of a stone or brick floor, a cast-iron ceilings, formed by the hoppers, and a number of cast-iron columns between both, the place most exposed to the various causes of conflagration is thus effectually protected, and rendered fireproof, While the simplicity and economy displayed in the construction of its parts, permit the erection of fire-proof grain-storebouses at a less expense than has ever heretofore been efl'ected.

What 1 claim as my invention,'a nd desire to secure by Letters Patent, is-

1. Supporting grain-bins upon one central column, in the manner substantially as and for the purpose described.

2. The hollow cast-iron column A, with the dischargespout B and hopper-plate G, constructed in the manner and for the purpose substantially as herein set forth.

3. The hopper D, constructed substantially as described, in combination with one central supporting-column; for the purposes herein set forth.
