which the following is a specification.

The present invention relates to improvements in silos.

The primary object of the invention is to construct a silo that is capable of being increased or-diminished in its capacity for holding ensilage, and also in providing j means by whichsections of the silomay be handled in order to increase or diminish the size of the silo.

The invention consists essentially in'providing a silo made up of-sections or units, and in means for raising and lowering these units as will be described.

It further consists in certain novel combinations and arrangements of parts whereby the sections or units of the siloare supas will be more fully hereinafter set forth.

In the accompanying drawings I" havev illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of the invention.

Figure 1 is a side elevation of a silo showing the complete embodiment of my invention. Fig. 2 is a side elevation of the mast, the silo being omitted, showing the cover lifting means, and the hoisting devices for the units or sections of the silo. Fig. 3 is an enlarged view showing the cover for the silo, and a slidable sleeve in section, and showing also two of the silo units and the means for lifting said units. Fig. 1 is an end view of one of the cam bolts used in the construction of the silo. Fig. 5 is,a side elevation of the bolt of Fig. 4.

In the preferred embodiment of my in-. vention, I employ a central mast or pole 1, which is illustrated as a metal tube, formed with a concrete base 2, and a concrete foun- Specification of Letters Patent.

they are.connectedto the upper end of the sleeve 4, and a rigid relationship is thus established between the bars and the sleeve.

At the end of'each bar a bracket 8 is provlded to support a pulley 9, and by means of the brackets 10 integral with the hub 5, a

pair'of pulleys 11 are journaled close in to the sleeve 4. At the lower end of the hub 5, a flange 12 is formed, and about this flange. the conical cover 13 of the silo is secured by means of rivets 14. y

- The sleeve, hub, radial bars and. cover, are allrigid with each'other and are movable with relation to the rnast 1, the sleeve and hub being slidable on the mast. Thus the cover may be raised or lowered as desired, and to accomplish this result a pair of pulleys 15 are permanently located near the top of the mast and supportedby means of the bracketed sleeve 16, which is fixed to the mast in a suitable manner. At l717 the hoisting:L ropes 18'18 are secured to the mast. ach of these ropes is then extended down and under one of the pulleys 11, and then up overone of the pulleys 1-5, and as shown in the drawings the end of the hoisting rope is tied to a post or stake 19. By means of these two hoisting ropes 18, it will be apparent that the cover may be raised or lowered on the mast 1. The silo is built up around this permanent and fixed mast 1. Itis made up of a multiplicity of rings or bands 20, and as 'clearlyseen in Fig. 1, these bands or rings increase in diameter and are superimposed one upon another. Referring to Fig. 3, two of these rings are shown in section, and they are illustrated as metallic bands bolted or riveted together at 21. Each of the bands is provided with four diametrically arranged bolt holes 22 adapted to receive the threaded bolts 23, and each of these bolts is provided with a cam head 24 and flattened faces 25. After the bands or sections have been lifted to position, the bolts are passed through the openings 22 with the bolt heads outside, and by means of nut 26 and washer 27, these bolts are clamped through the rings 20. Then by turning the cam heads, successively, the section or ring 20 may be further lifted, although but slightly, and thus forced into closer frictional engagement with its next lower section'or band. A tool applied to the Hat places 25 will turn the bolts and as they are turned the cam head frictionally engages the lower edge of the upper section and lifts the section as described. Each ring is sup ported upon the bolt heads 24 clamped in 'the next lower ring as shown in Figs. 1 and 3.

In increasing or decreasing the capacity of the silo the ropes 28 and hooks 29 are employed. There arefour

ropes

28 and 29; and'from the drawings it will' be apparent that these ropes are passed over thepulleys 9, and the hooks are adapted to'engage in the bolt holes 22 on the rings or sections 20. Thus when a section 20 is to be moved, its bolts 23 are removed and the four hooks 29 on the ropes 28 are attached to the ring, and

after the ropes are disengaged from the stake 19, the ring or section may be lowered. All the bolts 23 on the next lower ring, are now removed, and the upper ring may be lowered to the ground passing down over the entireheight of the silo fromtop to bottom. This is accomplished by reason of the fact that each upper ring is greater in Gopies of this patent may be obtained for stance, .when loading the silo; the ensilage is piled into the silo to its top ring.- Then another ring is added; and the ensilage "packed, and the rings are added and ensilage alternately packed until asufficient capacity has been reached. The movable cover l3 is aslarge as the greatest diameter of the largest ring, and consequently'th cover is morestable, but if desired, guy ropes or braces may be utilizedtOsupport the'mast whenever necessary. a

- It is evident that silo constructed as above 1 set-forth is facile in manipulatiomefficient in operation, and economlcal n performing the functions for which it is intended.

I claim:

adapted to close the silo at all possible heights. The ensilage packed in the siloand about the mast, renders the structure A silo comprising a multiplicity of taper j ing perforated metallic ring sections .of 1ncreasing diameter superimposed one upon another,;and each section having bolts w1th cam shaped heads thereon for raising the next uppersection into closer frictional contact with its lower section In testimony whereof I aflix my signature in presence of two witnesses.
