t fur her consi ts of other novel fea ur of construction, all as will be hereinafter fully set forth.

The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, such detail construction being one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings Figure 1 represents a perspective view of a portion of a silo embodying my invention.

Fig. 2 represents a vertical section of the wall of the silo, the section being taken on line 22 of Fig. 1. I

Fig. 3 represents a section on the line w-w in Fig. 2.

Fig. 4 represents a perspective View of a block from which the silo is constructed.

Fig. 5 represents a side view of a block.

Fig. 6 represents a sectional view through a solid block, as shown in Fig. 5.

Fig. 7 represents a detail sectional view of the upper portion of the wall and a part of the roofor cover.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, the reference numerals 1 indicate base-blocks which are supported upon the foundation of the silo in a circular or other desired or required configuration. Said blocks have flat bottoms, 2, and tops, 3, and plane and slightly curved inner walls, 4, and outer walls, 5,

' place.

'theupper and outer corners, 6, being beveled'. The blocks are hollow and have the ends of their interiors, 7, open to register 7 with the ends of the adjoining blocks. The outer walls of the blocks, 8, forming the sill of the silo-door, have openings, 9, into the interior of the blocks. The base blocks are curved upon circles corresponding to thecurvature of the base. The staves of the silo are composed of blocks, 10, the lower ends of the lower set of whichjrest upon the base-blocks and have their hollow interiors, 1l, communicating with the interiors of the base-blocks through openings, 12 in the tops of the same. The uppermost blocks of the wall are open, as at 21, and spaced from the cover or root, 22, of the silo, so that. each stave formed by the hollow blocks will form an air-flue open at its top and bottom. drawings the blocks are formed at one side with corner flanges, 13, and upon the other side with a tongue, 14, which fits between the fl ge f h adj ining bl k, s that he sides of the blo s interlock w en n w t a Pa i 5, lon i ud na o he h low interior and bracing the inner and outer Wal s of each o and said W l s a e trans versely curved to form segments of the circular outlines of the assembled structure. The ends of the blocks are formed with shouldered rabbets, 16, and tongues, 17, which fit into each other to form continuous overlapping joints between the ends of the blocks and thus form a continuous inner and outer surface of the wall of the silo.

The sides and partition of one tongue at the end of each block have longitudinal slots, 18, through which a hoop 0r tie, 19, is passed circumferentially through the blocks when assembled, and has its ends locked by nuts or heads, 20, at the jambs of the doors openings, thus retaining the blocks of a circumferential group of blocks in place and laterally clamped together. Such hoops may be formed from plain metallic rods, twisted metallic rods or wire-rope or any other metallic annular tie, and the ends of the hoops can be secured by any suitable means which will prevent movement of the hoops.

sllo.

In the construction shown in the The blocks are preferably formed- The meeting faces and edges of the blocks are If desired, the blocks can be solid and Without cavities, as illustrated in Figs. 5

and 6. i

, By constructing the silo from hollow blocks,'lightness is combined with strength in the structure, and, as the ends of-the hollow blocks are vertically connected, a cylindrical and vertically spaced hollow wall is formed, taking in air at the lower ends of its contents will not get either overheated nor freeze byextreme changes of temperature.

' The silo is fireproof and, the joints between the blocks interlocking, said joints require i comparatively little cement to hold the blocks together and to render the joints air and waterproof. The blocks may be made from clay or similar substances,-burned' or baked to be solid, and impervious, or they-may be formed from concrete composltlon suitably blocks here shown as the tongues which are molded and dried, and treated to be air and waterproof.

As the hoops pass through or are embedded in-that portion of the'superimposed exterior of'and overlap the [tongues of the adjoining blocks, the overlapping outer tongues will beheld by the hoops against displacement from outward pressure of the '-contents offthe silo, and confine the overlappedv adjoining tongues of the adjoining blocks and so form a firm and positive joint.

While the sides of the blocks are disclosed H as forming tongue and groove j oints, and

"'such construction is preferable on account of My! 0!; this patent may bpobtained for strengthand tightness of joints, the sides may be formed in any suitable manner to accomplish the desired results. By embedding the hoops or ties on the blocks they are not exposed to the elements and are not only less liable to rust and other damages, but also will not expand and contract to such an extent, thus insuring more positive action and serving to properly hold the joints in position.

Other modes of applying the principle of my invention may be employed for the mode herein explained. Change may therefore be made as regards the mechanism thus disclosed, provided the principles of construction set forth in the following claim are employed.

Having thus desoribed'my invention what I claim as new and desire to secure by Letters Patent, is

A silo having its walls formed of hollow blocks having their inner faces curved and their adjoining sides fittedtogether and with their meeting ends formed with overlapping shouldered rabbets and tongues respectively interlocking with each other to form joints forming a continuous inner and outer sure face of the wall of the silo, said tongues having apertured slots, cement uniting the meeting faces of the ends of the blocks forming an air and watertight joint, and tie rods transversely extending through the tongues of said joints to reinforce them.
