To all whom it may concern: l Y -Be it known `that l, JoinTl KRUZICIQa citizen of the United States, :residing at lVinamac, in the county of Pulaski and State of lIndiana, have invented a new and useful Silo-Mold; and 4I do hereby declare the following to be a full; clear, and eXact description of the invention, such as will enable others skilled in the art 'to which it appertains to make and'use the' same.

This`VY invention relates to an improved mold or form'for molding or constructing cement* or concrete silos, or other plastic similar structures or'cisterns., f

AAs an objectfof the invention it is the aim to provide upper and'lower segmentaljsheet metal :angle ironjoined or' 5united 'in sequence, to form upper and lower substantially circular rings connected by vertically arranged plates, thel adjacent edge portions of which are connected by strips T-shaped in cross section, thereby-forming innerv and outer walls, between which plastic material may be deposited to form a silo or other similar plastic structure.

Another object of the invention is the provision of a silo'mold or form comprising inner and outer walls provided with offset sectional parts to form an oii'set hollow portion to the silo, the inner wall of the offset lsectional part being substantially of apolygonal contour Y andy having reinforcing strips T-shaped in cross section, the upper and lower end portions of said T-shaped strip being slitted or slotted to receivethe upper and lower angular reinforcing strips.

Another feature of the invention isgth'e provision of connecting straps for connectingthe inner and outer walls of the mold, and after the concrete or other plastic material has become set, that is, of therst tier of the silo 'said'v connecting -strips are removed, and additional inner and outer walls, to form the second tier ofthe silo are' bolted as shown to the upper portions of the first inner and outer walls, and so on until the silol has 'been' completed."' fg.:

In practical ields'fthe details of'construotion may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure l is a view in side elevation of the first and second, tiersof the inner and outer walls of the mold.

-forming Va rigid: structure. .ing or uniting strips are constructed of sheet .'Fig. 5. Fig.` 7 is -a sectional viewV on line n l I ,1 7 of Flg. 5. Flg. 8 is a sectional view on line -8-8 of Fig. 2. Fig. -9 isa sectional view Online 9 9 of Fig. 2. Fig. l0 is a detail view of one of'thestrips 5l. Fig. 1l is a'detail view of one of the strips 35. Figs. Hand-"13 are detailviews showing a modified vform of extension walls. Referring more especially to the drawing,.l 'and 2 designate the outer and inner vwalls of the mold, and it may be well to state that the accompanying drawings are merely 'used for the purpose of illustration, and

moreover, the. shape or contour of the mold 'may'be'varied In other words, the walls may be vdrawn exactly circular, instead of polygonal in outline. The inner and outer walls comprise upper. and lower segmental strips 3 and 4, angular in cross section. These segmental sectional strips, angular in cross section are connected by shorter strips 5 and 6 angular in cross section, by means of bolts and nuts 7 and 8.' The upper and lower segmental strips 3 of the outer wall areconnected by the vertical Wall plates 9, also bolted to? the strips 3 by means of the bolts'?, and similar wall plates 10 are bolted by the bolts 8 to the upper and lower strips 4 of the inner Wall. Connected by means of bolts 11 and l2 to the adjacent edge portions of the wall plates 9 and -l0 of the inner and outer walls are connecting or uniting strips 18 and 14 T-shaped in cross section, thereby These' connectmetalbentupon themselves as shown in Fig. l() to f orm the T-shaped contour in cross section, and it will ybe noted that the upper and lower ends of the connecting or uniting strips'- overlap the verticalplarts or iianges of thestrips 3 andv 4, as shown in Fig. 9. It will be observed that the horizontal flanges of the strips and 4; angular, in cross section are provided4 with apertures or holes 16,?-to receive bolts, for bolting super-imposed inlil fill

ner and outer walls upon the lower walls, in order to construct another tier to the silo. .l`he horizontal flanges of the up er strips 8 and 4 of the inner and outer wa ls are connected by metallic straps 17 (Fi 2) having bent'over ends 18 to receive sai horizontal flanges. However, before the inner and outer walls of the second tier of the silo are bolted upon the first inner and outer walls, the straps 17 are removed, but are not removed until the concrete, cement or other plastic` material has become well set.

The walls 1 and 2 are provided with offset extension walls 20 and 21 of the shape or contour as shown Figs 2, 3, 4, and 7. The extension wall comprises upper and

lower reinforcing strips

22 and 23, which are angular in plan view, and angular in cross section. As will be observed one of the lates9 on each side of the extension wall20is nt as shown at 23 forming a part 24 (Fig.2) which is bolted at to the downwardly extending flange 26 of the upper strip 22 and to the flange 27 of the lower stri 23, as shown at 2S, (Fig. 1). The part 24 is bent at 29 forming a short flange 30 (Fig. 1). The flanges B0 abut against the flanges 31 of the plate 32, which is bolted at 33 to the downwardly extending flange of the strip 22 as shown at B3. and to the upwardly extending flan e 27 of the lower strip 23, as shown at 34 igs. 1, 2, 3, 4 and 5). Where the fla. as 30 and 3l abut, they are connected by the vertical reinforcing strip 35 T-shaped in cross section which are bolted at 36 to said flanges 30 and 31 (Figs. 2 and 3). The strips 35 are formed with sheet metal, and are bent upon themselves to form the T-shaped contour, and the. upper and lower ends of the flanges 38 of said strips are beveled off, as shown to fit the corners of the u per and lower sii-

ips

22 and 28, as shown c early in Figs. 1 and f-l. thereby rciiiforcin the structure. 'lhc bolts 3G may be inserted through any of the apertures 39. Where the inner wall 2 merges or blends into the extension wall 21 angular pliites 40 are provided, which are boited at 41 (Fig. 2) to the angular strips 4 above and below, and the arms 42 of the platos 4() are bolted at 43 to the strips 44 (liigs. 2 and 5), angular in cross section. llates i5 are connected also at 43 to the upper and lower strips 44, and are provided with angular extending flanges 46 abutting the flanges 47 of the flate 48, which in turn is bolted at 40 to the upper and lower angular strip 44 (Figs. 2 and 5).

Each of the strips 44 is constructed in one piece, and in order that the same may be bent to the shape shown, particularl in Fig. 2, the horizontal flange of each 0f t e stri s 44 is severed as shown, so that parts of t e horizontal flange may overlap, as illustrated. Bolted at 50 to the inner surfaces of the flanges 46 and 47 are reinforcing strips 5l T-shaped in cross section (Figs. 2 and 5i. and similar in construction to the strips 25:3. and the T portions of the strips 5l are interposed between tlie flanges 46 and 47 and the vertical flanges of the strips 44, and in order to permit of this construction the flanges 54 of the T-shaped strips :3l arc slotted or slitted, as shown at 55 (Figs. 2 and 5) to receive the vertical flanges of the strips 44, thereby rigidly reinforcing the ex` tension offset wall 21. onnecting the horizontal flan es of the upper strips 22 and 44 are meta lic straps 56 iaving hooked ends 57, so as to hold the offset extension walls rigid with relation to each other. Connecting the o posite flanges of upper strips l2 is a metalic strap 58 having hooked ends 5f), thereby holding the opposite side walls of the offset extension wall 2O in their proper position. The offset extension walls 20 and 21 may also be constructed by the modified form of plates shown in Figs. 12 and 1:5. which plates 60 are constructed of the angular strips 61, 62 and the troughshapcd strips 63 and the plates 64, bolted together in the i manner shown, as at 66.

As before stated, the various sectional parts of the mold may be made in other shapes, either as shown, or circular or otlier wise.

The invention having been set forth, what is claimed as new and useful is A silo mold comprising inner and outer concentric walls, said walls having correspondingly constructed offset extension walls conforming in contour to each other, dc signed to mold a hollow offset extension wall to the silo, each of the offset extension walls consisting of upper and lower strips angular in cross section, plates connect-ing the upper and lower strips, reinforcing strips T- shaped in cross section connecting the adjacent edge portions of said plate and having their upper and lower ends disposed between the strip and said plates, and a connecting strap between the up er strips of the offset extension walls, the 'F-sliaped strips of one of the extension walls having their upper and lower ends slotted to receive the vertical flanges of the angular upper and lower strips.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
