IA" VEN T OR ZZMIFOTE J UNITED TPEAE FF PERRY M. roan, or TONGANOXIE, KANSAS.

12) all t mid y concern Be it known that I, BERRY M. Form, a citizen of the United States, residing at longanoxie, in the county of Leavenworth and State of Kansas, have invented certain 'uew 'a nd useful Improvements in Silos; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanyin drawings, and to letters or figures of re erence marked thereon, which form a part of this specification.

This invention relates to improvements in silos.

The object of the invention is to provide in a silo a convenient, economical, and practical, structure, which will be substantially air-tight and which will prevent the silo as a whole from contracting and expanding under changing climatic conditions.

The :invention also relates to the specific details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in' the claims.

In the drawings: Figure l is a perspective view of a silo constructed in accordance with my invention. Fig. 2 is a horizontal section of the same. Fig. 3 is a detail vertical section of the foundation of the silo. Fig. 4 is an enlarged detail horizontal sec tion of a portion of the silo.

The same numerals refer to like parts in all the figures.

1, indicates a circular bed of concrete em bedded in the earth, and projecting some distance above the same, as indicated at 2. Embedded in the mass of concrete 1, are vertical posts 3, suitably spaced apart, and secured together at their upper ends by intermediate sills 4i, and tied together intermediate sills 4, and the mass of concrete, by a band 5.

Extending from "dj'atent posts, and on the inside thereof, metal sheets 43. The vertical edges of each metal sheet are bent outwardly to provide flanges 7, which fit in vertical grooves 8, formed in the posts 3. Each post 3, is provided with two of the grooves 8, so as to accommodate the flanges 7, of two adjacent sheets 6, as more clearly shown in Fig. 4. The lowermost metal sheets 6, have their lower ed es turned inwardly, to provide flanges 9, which forms an anchor in the concrete. Secured a vertical flange 13.

Serial No. 703,923.

to the outer surface of each of the lower metal sheets, is a strip of metal 10, riveted as at 11, and bent outwardly to form a shelf 12, and then bent downwardly to provide These strips form anchors in the bed of concrete and serve to produce a substantial and rigid structure when the parts are assembled. In assembling the metal sheets, the top of the lower sheets overlap the inner surfaces of the bottom portions of the upper sheets, and then the sheets are riveted, as at 14. After the ositioned, a strip 15, is placed over the side end portions of two adjacent strips, as shown clearly in Fig. 4. These strips extend from the top to the bottom of the silo, and are located opposite each post 3, and their overlapping ends are secured by nails 17. The nails pass through the metal sheets 6, and into the posts so as to secure the parts together and form tight oints.

The bed or mass of concrete extends over the surface of the earth inside the silo, to form a floor 18, the outer edge portion of the floor tapering up to the lining formed by the sheets, and approximately to the level of the extended portion 2, of the foundation.

Doors 19 may be provided at suitable points between the posts 3, and are mounted in frame 20, the sheets 6, being cut out adjacent the frames, as will be understood.

A top may be bent over the silo, but as this forms no part of the improvement, it has been omitted to better illustrate the invention.

The inner surface of the sheets and strips are coated with tar or other protecting agent to fill up the cracks and crevices, so as to make the interior of the silo as smooth ,and as air-tight as possible.

The arrangement of the parts insures of economy in building'and at the same time affords ample stability.

What I claim is:

1. In a silo, the combination of a concrete base, posts having their ends embedded in the base and formed on their inner surfaces with open vertical parallel grooves spaced from the Vertical edges of said posts, metal sheets formin the walls of the silo, the vert"'-.-a.l ends 0 the sh ets being bent outwardly to provide flanges which are seated in the vertical parallel grooves, the horizontal end portions of the sheets overlapping, means for fastening the overlapping ends together, a vertical plate secured to the inner surface of each wertical post and overlapping the vertical ends of adjacent sheets, anchors secured to the lower sheets and embedded in the concrete.

2'. In a silo, the combination of a concrete foundation which extends above the level of the soil, vertical posts having their lower ends embedded in the foundation, sheet metal lining on the inside of the posts to form the walls of the silo, a concrete floor having its edges tapering up to the lining and forming an integral part of the foundation, and anchors secured to the lower portion of the lining and embedded in the foundation.

ends embedded in the concrete foundation,

sheet metal lining secured to the inner surfaces of the posts to provide the walls of the silo, the lower end of the sheet metal lining being bent to form an anchor in the concrete foundation, angular shape strips secured to the lower outer surface of the lining to form an anchor which is embedded in the concrete foundation, and braces for holding the posts against lateral movement.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
