Beit known that I, CHARLES?. COOPER,

a citizen ofthe United` States, residing at .Rutlan d in the county of Rutland and State y of Vermont,have invented'certain new and,`

useful` Improvements `in Bins, `of which` theA following is a specification.`

j or silos constructed from Wooden sta-ves is `that by reason of the'fact that they are made of substantial height and are subjected to severe strains both from internal pressure and from `external or wind pressure, theyV are apt, after the silo has been in `use for some time, to lean, twist, blow in, or Otherwise become misshapen and distorted.

The object of the present invent-ion is to `provide aconstruction for theV binor silo which is capableV of effectively overcoming such difficulty, andthis is` accomplished by providing` a specially formed base, of concrete or the like, to which the staves are individually ancho-red e so as e to be held against movement either laterally or vertlcally whereby effectively to resist all lateral strains upon the structure whether internal or external; e j f In the .accompanying drawings forming' parthereof, l have illustrated a preferred embodiment of my invention. Thus, Figure l is` a. front view of the lower portion of the improved bin partially broken away and in section, and showing the forms in place by means of which the concrete foundation or base is formed. Fig. 2 is a fragmentary vertical sectional view showing,l a. portion of the completed bin having van inner cove formed of concrete and constituting the annular npstanding portion to which the peripheral side wall of the bin is secured. Fig. 3 is aV perspective view ofthe lower end of oneot the wooden staves showing one form'cf anchoring socket. f

lllhiile the drawings illustrate but one embodiment of the invention, it will be understood that various changes in form, arrangement and construction may be adopted without departing from the spiritand scope of the invention as expressed in the appended claims.

The silo comprises a foundation or base it annular in form and supporting the pe 1921. Serial N0. 472,762.

. ripheral wall structure consistingof a plurality of staves 5. 6 designates an upstanding annular portion of t-he base Ll, to which the lower ends of the staves are rigidly fastened.` This is accomplished through the inediiun of radial projections 7 enteringsockets or recesses: 8 provided in the inner sides of the staves at their lower ends. Said projections are held in engagement with Vsuch recesses by Vmeans of hoops 9.

The base 4 is preferably constructed of concrete, the annular` portion 6 thereof being preferably made integra-l with the lower or main portion as shown in Fig. l. The annular portion 6 is formed of somewhat smaller diameter than the lower portion to pro-vide a shoulder l() upon which the lower ends of the staves 5 rest. In forming the base t with the annular portion 6, suitable formwork is employed in conjunction with the st-aves themselves. Thus 1l indicates the inner formwork having suitable bracing' means 12, and 13 designatesthe outer form# work which is secured in place in any suitable manner` (not shown) and terminates at .its upper end substantially flush with the shoulder 10.

The stavest are of ordinary construction, having parallel interfitting edges, and are recessed at their lower ends prior to being; assembled, to provide the sockets or recesses 8., Obviously these recesses may be of any suitable or desired shape and preferably two recesses are provided in each stave at a substantial distance apart longitudinally of the stave.

The projections 7, it will be understood, are formed by the concret-e entering the recesses 8 as it is being poured,to form the annular portion 6, care being taken that the concrete completely fills said recesses. llhen, Y therefore, the lower -ends of the staves are clamped snugly around the annular portion 6 by the hoops 9, the projections 7 serve to resist vertical movement of the staves, and the latter, being snugly bound together, coact effectively to resist any tendency o-f the bin to lean or sway laterally. To enable lthe hoops 9 thus firmly to clamp the lower ends of the staves to the annular base portion 6, and thereby enable the projections 7 to?l resist lateral strains, the hoops 9 are preferably made adjustable in anysuitable way. Thus, clampinglugs 14 may be employed to which the opposite ends of the hoopsgare adjustablyfsecured as by;V

means of Anuts 15.

When the bin is employed as a silo,"it is s desirable to provide vazconcave.bottom or` will -be obvious, however, 1that the cove may 'be made integral, if desired, and ofV any preferred for which is of avery-practical character. .The construction `is exceedinglyvsimple `and'yet -is exceedingly effective as a ineans'for :over- It will be yapparent that I have provided anYimprovedconstruction for a bin or silo,

coming theyobjection 'to stave siloshereinbefore pointedcut.' vObviously'the interengageinent of each ofthe staves .with the base, and lespecially l*with longitudinally spaced project-ions on the 'annular portion which extends upwardly a vsubstantial disftance' into the bin, serves to `resist .lateral pressure upon the bin lin a 'directio'iit perpendicular to the stave, so that with all of the rstaves-firinly bound together, pressure upon any side of the bin is ve'ectively resisted.

I claim as my invention:

l. A bin comprising, in combination, a base, a'` wall structure-*formed from a plu- Aiality of staves :ha-ving their rlower ends lsupported by the base,` saidbaseihaving a portion rising therefrom to 4a substantial 'height within the wall structure, and means foi'- rigidly securing -the lower ends of the staves-to said annular vportion including interlitting projections 'andrecesses in the anfnulai" portion and staves respectively, and means such as hoops foryholding said project-ions and recesses ininterengageinent.

2. A bin in the nature of a Ysilo comprisfing a 'base lia-ving van upwardly Eextending portion, and a 'wall 'structure 'formed from La plurality of wooden staves and surrounding atiits `lower end said lupstaiidingportion ofthe 'base,\said -staves being shaped for inter-locking engagement with integral parts of said upstanding portion of the base whereby to resist lateral strains upon the wall structure.

3. A bin comprising an annular upstanding basev portion, a wall structurecomposed ofa .plurality of staves,vineans firmly bind- ]ing "the strives; together and around said base portion,"said basey portion being formed of concrete'andisaid*staves each 'having a plurality of Arecesses therein" spaced apart longitudinally 'of the stave', which recesses become vfilled `Witlrthel concret'ewhen the `latter is being Vpoured to"'formV the base whereby to provide radi'alpiojections"tendiing to resist lateral strain Aupon the bin.

`f4'. In -a bin, the fcoin'bination of an upright base-portionand a wall structure lia'vinga stave formed of'wood land 'having a recess 'in itslower end, said base being formed of concrete so asto cause a 'portion thereof to enter the recess in'said stave, and

Vmeans for firmly ybinding the stave tosaid base portion.

5.` Theinethod lof makingI a wooden stave bin which consists in arranging suitable forms whereby to'zprovide a `base of concrete with an'upstanding annular portion 'rising a' substantial distance into vthe wall structure formed by the 'staves, and anchoring the wall structure to thebase by tampingiportions of 'theconcrete as the latter ispoured to 'form the upstanding base portion, into-'recesses provided in the lower ends of .the staves and by binding the Vlower ends of the stavestogether and around'said upstanding base portion.

In testimony whereof, I `haverhereunto set my h'and.
