To all whom t may concern.

Be it known that l, donn W. Goonwrn, a citizen of the llnited States, residin at Neodesha, in the county of Wilson, tate of Kansas, have invented a new and usetul Metal Form for Constructing Silo and other Cement Walls; and l 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 invention relates to an` improved metal torni. for constructing silo and other cement walls, and one of the objects ofthe invention is to provide a simple, eilclent and practical form of this kind comprising tic material may be deposited therebetween inner and outer sheet metal members, between which sections of 'a silo or other wall may be constructed, each section of the wall being constructed successively until the entire wall isy constructed.

A. further object ot the invention is the provision of improved means for holding the inner and outer sheet metal members in spaced relations, one rigid with relation to the other, whereby the cement or other plasto form the section of wall.

A further, object of the invention is the provision of means for holding the inner and outer sheet metal members in adjusted spaced relation, whereby walls oil did'erent thicknesses may be constructed, or walls thicker at one end than at the other may be constructed..l

A further object oit the invention is the provision of improved means for bowing the inner and outer sheet metal spring members on diderent arcs, whereby walls of dif- :ferent diameters may| be constructed.

lln practical elds the details ot construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further :features and combinations ot parts as hereinafter set forth, shown in the drawings and; claimed.

1n the drawings Figure 1 is a plan view of the inner and outer sheet metal members, bowed so as to construct a curved wall, which may constitute a section ol a silo wall.

Fig. 2 is a horizontal sectional view of said sheet metal form comprising said inner and outer sheet metal plates.

Fig. 3 is a detail perspective view ot the inner and outer sheet metal spring plates or members, showing the means for holdin them in did'erent adjusted positions an spaced trom each other end plates, whereby the end ot the wall lto be constructed may be formed, to constitute a art ot a door jamb.

ig. d is a sectional view on line 4--4 ol which cement or other plastic material is designedto be deposited to form a section of a silo for other wall. Each end of the outer 0plate 2 is provided with an outwardly turne radially disposed flange 3. To the ends of the inner sheet metal plate 1 plates or members t are connected by the hinges 5. The plates d are provided with elongated slots 6. lln order to form either end surtace (which may constitute a door jamb or the like) ofthe wall as shown in Fig. 1, one or the other ot said plates d, is arranged to overlie the dange 3, there being bolts i passing through the flanges 3 and through the slots 6, to receive the nuts 'la to assist in holding the inner and outer plates in dit ferent adjusted spaced relations.

Carried by the outer 8. The arms 9 ot these strips or straps eX- tendthe full height of said outer plate 2 and are riveted thereto as shown at 10, while the arms 11 overlie the upper edge of the plate 2. Pivoted to the are the links 13, which are provided with slots 1t. ldiveted at 15 to the inner plate 1 are the angular brackets 16 and extending through the slots 14: and through the arms 17 ot said brackets 16 are the bolts 18 having nuts 19. By this construction the inner and outer plates 1 and 2 may be held in did'erent adjusted spaced relations according to the thickness ol wall to be constructed'. By means of the long arms 9 of the angular straps or strips (which are rigid with relation to the arms 11 and at right angle thereto) the entire height of the outer plate 2.is held in parallelism with the inner plate 1. The inner plate adjacent its ends and near the upper and lower edges angular brackets 20 are riveted as shown at 21. The

and the hingedly j arms 1l as shown at 12' plate 2 near its ends,

' nected, by passingk their angular end 37 1n parallelism with the outer plate inner plate 1 near its upper and lower edges is provided with eyes 22" through which the rod sections 23 extend. Pivoted to the brackets'20 as shown at 24 are rod sections 25, which are in turn connected to the end rod sections 23' by means of turn buckle sleeves 26. The end rod sections 23 are in turn vconnected to the central rod section 23 by the threaded' turn buckles 27, and it is `to be observed that by adjusting the turn b'uckles 26 and 27 in one direction, the rod sections 23 may be moved axially toward each other, whereby the inner plate 1 may be curved on di'erent arcs. By means of the eyes 22 the rod sections are held, so that the plate 1 may assume a curved sha e concentric with the rod sections, and w ereby a cement wall maybe constructed havin the desired curvature. The outer face o lthe outer plate 2 is also provided with eyes 28,- through which the rod sections 29 ass, there being turn buckle sleeves 30threa ed to and connecting the rod sections 2 9. Additional rod sections 31 are connected to the end rod sections 29 by theturn buckle sleeves 32. Said rod sections 31 (which are adjacent the upper and lower edges ofthe outer plate 2) are pivoted at 33 to the angular brackets 34.

f It is to be noted that by adjusting the turn 30 buckle sleeves 30 and 32 in the desired direction the rod sections 29 and 31 may be axially extended, thereby giving the outer plate 2 the desired curvature,l to conform concentrically with the curvature of the inner plate. The inner plate 1 at its ends near its lower edge is provided with angular brackets 35, to which the rods 36 are conthrough the openings 38. The adjacent ends of the rods'36 are threads, and connecting these threaded ends is a turn-buckle sleeve 39. By adjusting the turn buckle sleeve 39 in the desired direction thereby moving the rods 36 axially away trom each other, the inner plate 1 may be reinforced, and its oposite ends near its lower edge may be he d therebyl preventing displacement of the 2 andplate. In constructing a silo wall substantially as shown in Figs. 1 and 2, starting from one jamb of a door opening of a silo, the plates 1 and 2 (which are constructed of sprlng sheet steel) are arranged with relatlon to each other as shown and curved so as to receivercement o r other plastic material between them. In order to form an end (which may constitute a jamb of a door opening), the plate 4 on the left is arranged as shown in Flgs. 1 and 3, and by means of the bolts 7 the plates 1 and 2 are prevented from becoming displaced, in fact preventedl from spreading. After one section of the wall is constructed said plates 1 and 2 may be moved to another position to form another segment of wall. This is continued, forming the various sections successively annularly, and one tier of sections on the other, until a complete silo may be constructed.

v-The invention having been set forth what is claimed as new and useful is In a metal form for molding cement segment wall sections, inner and cuter sheet metal spring plates, means carried by the outer faces of both plates for giving said plates concentric curvature, angular brackets on the inner plate near its ends and adjacent its upper edge, angular straps on the outer plate near its ends, one arm of each .strap extending the full height of the plate, and adjustable connections between said angular brackets and the angular straps for adjusting the inner and outer plates in spaced relation to each other, a transverse plate hingedly connected to each end of the inner plate and provided with adjustable connections with the corresponding end of the outer plate, whereby the end of the segment wall may be formed.

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