ALFRED VALLENTIN, OF CHICAGO, ILLNIS,

SILO'.

application inea Ju'n'e 1o, 1972s. serifu Np. 114,988.

The object of my inventionqis to combine,

the advantages of concrete and stave construction, to secure greater durability; to

Vreduce loss from freezing andV from temperature changes; and to provide a stave silo that shall .always be substantially tight.

In the drawings Fig. Y1 is Va sectional elevation of a cylindrical-silo, of my construction, in aplane laid through the axis of the tail of the ,sectional elevation shown lin Fig.

wall 12;

1,; Fig. 4 is fan enlarged sectional elevation in the plane indicated by line 4 4 in Fig. 1; Fig. 5 is a detail elevation of a portion of the inner, wooden `wall of my silo, viewed fromv the inside of the silo, with parts broken away; Fig. 6 is a sectional plan view taken on line 6-6 in Fig. 5.

Referring'to the drawings, on a concrete base ring` 10, laid on a concrete foundation 11, there'is erected a circular vertical concrete wall 12, provided with door openings 13. Wall 12 is preferably constructed of blocks 14 laid so as to overlap, and preferably tongued and grooved horizontally and vertically.V At suitable intervals, about three feet y distant, vertically, adjoining layers of blocks 14 are provided with dove` tail grooves 15, into which are entered wooden rings 16, made in sections, which protrude from the inner face 17 of concrete wall 12 a distance ofjseveral inches. In door openings 13 there are inserted suitable wooden doorframes 18 which project beyond face 17 a suihcient distance to have their inner faces Hush with the inner faces of tongued and Vgrooved wooden staves 19 which are set up against rings 16, about 2 distant from face 17, in a number of series, separated at suitable intervals by compression springs 20, interposed between the several series of staves. Staves19 are held in place against rings 16 not only by reason of the fact that their inner faces are narrower than their outer faces; the further fact that they are tongued and4 grooved; and the pressure of springs 20; but also by vvertical boards 21, overlapping each pair of staves 19 adjoining springs 20, which boards 21 are drawn against the underlying pair of staves 19 by internally threaded sleeves 22, engaging threaded bolts 23, anchoredin sleeves 22 being provided with numerous preferably squareyheads 24 adaptedto lbe engaged `by av suitable socket wrench, and with outwardly projecting circular `flanges 25, adapted to engageinwardly projecting flanges .26 at the bottom of suitablesockets 27 which are integral with lmetal plates 28, inlaid into the faces of boards 21 so :as vto be flush therewith. Springs 2O 'may befof any .desired construction. Aln the drawings I have shown them as elliptical *,Sprllgs,

entered into suitable vseats 29 in the adjoining faces 30 of 4Steves '29, yand :there further held by horizontal pins 31,1entered into faces `30. and projecting through openings 32 inispringsQO.VV j y .Y

VStaves 19,are preferably,setl onan elevated, peakediidge 33, formed on base lring 10, concentricrwih wall12. )In order-to prevent staves 19 from slipping off this ridge '33, I prefer to provide their lower ends with grooves 34, fitting'V on ridge 33. Between ridge 33 and wall 12 I form a sloping draingutter 34, with its highestvpoints adjoining door openingv 13, and thence pitching downward to a grated opening 35, in wall 12, opposite door openings 13. To close the spaces between wall 12 and stav-es 19 at the top, and at the same time to hold the upper ends of staves 19 in .fixed position with v'reference to wall 12, I provide preferably metallic sectional caps 36, having concentric Vdepending flanges 37 and 38, to receive be'- tween them the upper ends of staves 19, and depending flange 39 to enter groove 40, formed in the upper face of capblocks 41 of wall 12;V Openings 42 are provided in caps 36 to allow passage rof air 'entering through opening 3.5 and circulating upward between wall 12 and staves 19, through th-e spaces between rings 16 and boards 21. Between boards 21 andthos-e staves 19, against which boards arel drawn by sleeves22, I prefer to interpose elastic asbestos insulation strips 43 to exclude more perfectly all leakage of air and moisture. The several doorframes 18 are connected at their inner ends in any suitable wayY so as to make a surface flush with the inner face of adjoining staves 19. A suitable roof 44 and suitable doors 45 are provided, of any convenient construction.

It is manifest that the silo constructionA above described might be deviated from in particulars from the essentials of my invention. All such deviations I` intend "o cover by my claims. j

without departing Ijclaiin- I- y j A v1.1In a silo, the combination of an outer `Wall, preferably made of stony material,

Yhorizontal rings attached to the outer vvall,

on .the inside thereof, and an inner Wooden n Wall,cheld against said rings Without being :attached to said rings. f Y Q ,In a silo, the combination of verticalv Wvooden staves, arranged in a number of series, means for preventing the staves from yielding outvvardly, compression springs Y enteredbetween the several series of staves', boards `togcover the spaces betweenk the several seriesof staves, and means for drawing the boards into tight engagement with the adjoining staves. i

'3, In a silo, the combination of an outer Wall, made of` stony material, an inner Wooden Wall, separated from the. outer Wall so as to form air spaces between the Walls,

anda base supporting both Walls, said base being provided with a peaked Yelevated ridge,

supporting Vthev Wooden Wall, and With a sloping draingroove between such ridge and the outer Wall, leading to a suitable outlet.

' 4; In-.a silo, the combination of an outer ,Y ,Wall of stony material, an inner Wooden l 5.111 a silo, the combination Yof an outer,

Wall of stony material, an inner Wooden Wall separatedfrom the outer Wall so yas to forni air spaces, and n'ieaiis for closing the air spaces at the top, consisting of metal plates having concentric depending flanges, engaging both the npperends of the staves and also a groove formed in the upper face ofV tliefstony Wall.V

6. In 'a silo, the combination of an outer Wall, preferably iii-adeof concrete blocks, made 'so as toforinon the inside thereof,

at suitable distances, horizontal dovetailY grooves; Wooden rings held in these grooves and projecting therefrom; an inner Wooden Wall; and means for holding the inner Wall in contact with the rings, except at suitable-v intervals.
