MASONRY SIIiO.

Specification of Letters Patent. Patented June 28, 192LV Application led February 11, 1918. Serial No. 216,474..`

Y such as will enable others vskilled in the art Vsilo shown in Fig. l, but Von a reduced scale;

thel novel devices and combinations of de-V vices hereinafter described and definedfin the claims.V i

My invention is illustrated inthe accompanying drawings, wherein like notations refer to like partsthroughout theV several views. Y v

In said drawings, Y. Figure l, is a perspective view illustrating a silo embodying my invention;

F ig. 2 is a horizontal cross section of the Fig. 3 isa `detail' showing some of the samev parts appearing in Fig. 2, but on a larger scale; n

Figs. l and 5 are perspective views of one of the masonry slabs, of the kind` shown in Figs. l, 2 and 3, detached, and Fig. ibeing an inside view `and Fig. 5 being an outside View, with reference to the positions they occupy, when assembled in the silo wall.

Fig. 6 is a further detail showing some o f theJ same parts appearing in Fig. 3, `but on a still larger scale and as they would appear beforev the hoops werev drawnA together, at their opcn'ends, into their final position; and

F ig. 7 is a viewV similar to Fig. 3, but illustrating a slightlyymodified form of the maf slabs 9; the numeral l0 representsthe split oropenended drawrhoops provided with the customary draw bolt ll, `seated in; the A flanged en ClS of the hoop and adapted 'QQ .plied in Fig. l.

draw. the same together, when in proper working position. The numeral l2 Vrepresents a roof of any suitable structure, applied in any suitable or customary way to cover and close the top of the silo. Of course, in practice, the silo is also provided with suitable doors, not here shown.

The masonry slabs `9 are preferably composed of concrete, but may be made of the same material as brick or tiling; and I prefer to mold the same, so that they will have curved inner and outer faces, as illustrated in all the views, except Fig. 7; for the reason that I c au thereby lget a silo wall formed on a true circle, or substantially true circle,

arcs of the inner faces of the slabs,`as shown in the drawings.- (Figs. l, 2, 3 and 6.) I

may, however, make `the said` masonry slabs with Vparallel straight inner and outer faces, and then set the same, relative to each other, on the chords of comparatively short arcs, so as to thereby get a polyhedral wall, which is approximately circular, as illustrated in Fig. 7, the slabs there shown being marked with the reference 1 The masonry slabs 9 are all rabbeted on both their outer and their inner lvertical ad joining edges toV afford lseatsffa for packing means, which packing means is preferably in the form `ofstrips of wood, or other slightly compressible `heat insulating material 13, of. rectangular form in cross section,

-ing horizontal` edges, to afford seats b for similar packing material 14, as shown ap.-

The seating edgesfof the slabs 49 land 9g. are straight in cross section, at the upper and .lower ends of the slabs, but their vertical seating edges are convex, at one side, and con cave at the other, the `convexv or tenon surface being marked with the reference letter cand the concave surface or groovewithy the reference letter d inthe detached views, ,Figsid and 5.

Y Of course, the concave surface or. groove d of `one slab. is adapted to receive the convex surface or tenen c of the adjacent, slab. These details may be varied. at will. n f

. Havingregard to the relative positionsofi the slabs in the respective courses, if prefer toemploy slabs of unequal ylengthrfor the.

starting courses and have enough .different lengths, so that I can position the slabs of the successive courses, so that they will break Vare all of equal section measuredin the U Yplane of an arc Vof the silo, or on the radiufS thereof, and are so set that't'heir vertical Lrabf` beted surfaces aline with eachother, solas thereby to: afford continuous seats a Vfor the packing stripsl 13. rllhe packingfstrips 13 may, therefore, be of alength equal to the height of the silo, or they may beV made of shorter lengths and placed, one above the other to fill the seats'and pack ythe 'joints toV Vthe full height of the silo.A The slabs may,

Y ofcourse, be set in cement in Vthe customary way, and, after the gpackin'g*stripsl 13 have been placed in their seats, the'draw hoops 10 l are applied and will,.lof course, embrace the outer surfacesV of thefslabs and lthe outer faces ofthe 'outerY Vpacking strips. "Then when the draw bolts l1 `are"manipulated so faste tightenthe hoops, thewalls will be slightly'` contracted in the arc of the circle and this willl have the effect of making `the vertical walls Vofthe inner seats a. pinch the vertical faces A' of the `strips 1'3 seated therein,` and thus secure the said stripsin their, desired working position. This slight 'change in n the positionhof 'the slabs can be 'readilyunderstood by a comparison of the parts/shown in Fig.. 6 with the parts shown "inFigsQS or 7. In Fig. 'the partsy are shown as "they would appear, before'the ends Vof the drawhoop have been drawn tightly together, whereas," in Figs. 3 7, the parts are shown as they Vwould, appearfafter the hoop has beenltightened up. 1 1

Injrespect tothe horizontal ypackin strips 14, shownV inV working position1 infig'. Al, theyare Vapplied to the seatsqn? afforded by the rabbeted surfaces on the outside faces of are placedV in position to build up the wall and reliance is placed upon theweightofthe slabs, `or the thin coating of cement atfthe* slab joints to. hold the horizontal stripslli in their working positions. Whenwood is eni-V ployed as the material'for the packingstrips 13 and l14, and they are intended. toV remain 5 A.' masonry silo, A'constructed as `'above described,`has certain obvious advantages. It

Vis well `known that where masonry silos are j used inV sections of the country subject to eX- crete `foundation is' liable to heave and settle, under the action of the frost and the thawout, and if .the .concrete blocks of the. Ysilo walls'ar'e united solely by cementitious materials, the'change in the foundation, or the heaving and the settling of the walls will crack the cementitious materials and open the joints `between the blocks, or sometimes l even lcrack the blocks themselves. By constructing the slabs withthe rabbeted seats for great ythe change in temperatures from points above to points `below zero. Otherwise stated, if` there is'any heaving or settling of the foundationupon vwhich the silo vwall is set, or expansion or contraction ofthe Vwalls themselves, due to change of temperature, there will be no opening ofv the joints, as the slabs may move relative to eachother and relatively to the packing strips, while, nevertheless, keeping the packing strips `in such :position that the packedair-tight.

The foregoing is vespecially(advantageous 'whena silo ;is iirstbuilt in countriessubject to such change of 'temperature'.KV j

joints will be kept "Whenrthe wooden packing strips areemployed, it is, of course, obvious that thisisilo has the further importantl advantageof be- 'ingpractically' portable; or, in other words,

the same can be readily knockedv down and v- What I `claim is 1. The .combination withmasonry slabs disposed to, afforda I substantially cylindrical rmovedflfrom one place to another, whenever lso desired.' This 1s a .feature of importance 'to renters of farmswho ofttimes are obhged wall structure, said slabsbein'g rabb'e'ted VonV botli theirouter and inner vertical adjoining i H j j l edgesy and `onthefhorizon'tal edges, outer Ithe slabs, atrthe ends thereof, as the slabs and innerwooden joint strips interposed, re-
