15 Claims. (Cl. 189-3) This invention relates to prefabricated structures and more particularly to cribs for corn and the like.

The primary object of the invention is to provide a corn crib of demountable construction having improved means for connecting the several elements thereof.

Another object of the invention is to provide a corn crib having a demountable side wall and roof, wherein the side wall is formed of a plurality of panels so connectable with each other and with a roof as to provide a self-sustaining structure.

An additional object of the invention is to provide a corn crib having a side wall of panelled construction, in which wire mesh forming the main portion of the side wall is effectively locked in supporting frames without fixed attachment thereto.

A further object of the invention is to provide mesh wall panels having novel means for interlocking the mesh and their supporting frame.

Another object of the invention is to provide a mesh wall of panelled construction, in which adjoining panels cooperate to lock the mesh in its supports.

Other objects and advantages of the invention will appear hereinafter in the detailed description, be particularly pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Referring now in detail to the drawings in which like reference characters designate like parts, the improved corn crib of the present invention, while it may take various forms, has been shown as circular. If the crib is .to -be a permanent structure, as in the illustrated Patented June 5, 1956 embodiment, it is preferably mounted on a permanent base such as the illustrated concrete base, platform or floor 1. The structure may be anchored to this base by anchor bolts 2 embedded in the concrete, to which the crib is attached by suitable means such as the illustrated angle plates 3.

ice

Apart from its base, the crib is comprised of a circular side wall 4 on which is supported a conical roof 5. The

side wall, in turn, is formed of a plurality of wall panelsv 6, each comprised of one or more mesh or foraminous sheets 7 mounted in, carried by, supported on or connected or attached to a supporting frame 8.

Forming the frame 8 are a pair of spaced angle .irons 9, each serving as one lateral side of the panel and preferably extending the full height of the side wall 4. As shown in Figure 6, both angle irons are disposed with their inner legs 10 substantially parallel to the mesh or body 7 of the panel and their outer legs 11 disposed normal to and extending across the ends of the mesh. After the individual panels have been assembled, the adjacent sides of adjoining panels are readily connectable through their confronting or contiguous, normally disposed legs 11 to form the side wall of the crib, the angle irons 9 then serving as the posts, columns or uprights by which the crib is supported.

The side members or angle irons 9 of each panel are connected at either end and, depending upon the height of the panel, at intermediate points, by transversely extending bands or straps 12 which overlie and are bolted or otherwise connected to the inner or parallelly disposed legs 10. These bands are offset adjacent their connected ends so as also to overlie or lie outwardly of the longitudinal or vertical rods 13 of the mesh, this interlacing of bands and mesh, by strengthening the mesh, enhancing or increasing its resistance to bulging under pressure of the contents of the crib.

As previously mentioned, the mesh sheathing of the crib is in the form of mesh sheets connected to the angle irons. The initial width of the sheet is such that its transverse or horizontal bars, rods or strands 14 project substantially beyond the normal legs of the side members. To accommodate this length, each of these legs is slotted in correspondence with the longitudinal spacing of the transverse bars to provide a series of spaced slots, apertures or openings 15 in which the projecting ends of the transverse bars are received. After the ends of the bars have been inserted through the openings, they are crimped or bent transversely along the outer legs 11 normal to the inner legs 10 of the side members to hold the mesh in place, the side members, after the mesh is in place, then being joined by the aforementioned straps 12. If these straps are connected by bolting, as in the illustrated embodiment, it will usually be necessary to cut corresponding gaps in the end bars of the longitudinal bars or rods 13 of the mesh to provide space therefor.

Were the slots 15 each of substantially the same diameter as the transverse rods 14 which they receive, it would be necessary to stagger the slots of each side member relative to those of the confronting side member of an adjoinng panel to accommodate the crimped ends of the rods of both panels therebetween. Not only would this result in corresponding staggering of the lateral rods of adjoining panels, unless the gap between the side members was sufficient to accommodate both crimped ends in vertical alignment, but it would also introduce difficulties in manufacture. Accordingly, an important feature of the present invention is the configuration of the rod-receiving slots 15 relative to the rods. As shown in Figure 7, the slots of adjoining side members are aligned, but each in longitudinal dimension is substantially twice the diameter or thickness of the associated rod. Consequently, the end portion of each rod is enabled to be flexed, deformed or bent longitudinally of the panel so thatthe rod can occupy one or the other extremity of 'the elongated slot. If then the end portions of the mating or, corresponding rods. of all-adjOinlng seeion are, fiexed towards the opposite. ends of their slots, the crimped endsof bothtwill be, accommodated side by side longitudinally of the panels in the space therebetween,,thereby bothminimizing this space and enablingthecrimped ends to be clamped between the adjoining side members by bolting, of the latter. It is not intended to, bend the end portions of therods prior to connection of adjoining panels. Instead, the mesh initially will be able to slide longitudinally of its side rails'by virtue of the elongation of the slots. This, whenthe first two panels of the crib are connected, will'displace: the mesh of one up and the other'down vertically of the crib. However, by so lapping the crimped, ends of thetransverse rods of each of these first panels with those of a succeeding panel that the opposite end portions of the rods of each panel are caused to flex or deflect in opposite directions, the inherent resiliency of the transverse rods will bring the intermediate portions. of the corresponding rods of all panels into horizontal alignment. At the same time, the stress so applied between abutting lapping crimped ends will effectively interlock the mesh of all panels against relative longitudinal movement.

It will be. seen from Figure 4 that the side members or rails 9 have their lower ends spaced above the base 1, the opening therebelow being closed by the lowermost of the connecting bands 12. This spacing is to make use of the 2 aforementioned angle plates 3, which are anchored to the anchor bolts 2, as footings, the plates having their outer ends bolted to the lower ends of adjoining pairs of the side rails between the normally disposed legs 11.0f the latter.

The conical, roof 5 with which the crib is covered is supported on the side wall 4 through the angle irons 9 forming the supporting posts. For securing the roof in place, there may be attached to the inner leg 10 of one of the. adjacent angle irons of each cohnected pair a center clip or bracket 16, the outer end of which is bolted to the roof sheet 17 intermediate the ribs 18 of the latter. For further rigidity of connection, the ribs may be secured to the side wall 4 outwardly of the clips 16 by a hook bolt 19 having its hook clinched about one of the transverse bars 14 of the mesh sheathing.

While the roof 5 is provided with the usual removable cap 20through which the crib is filled and may also be provided with one or more manholes 21, it is desirable to have access to the interior of the crib through the side wall, at different levels, to facilitate emptying of cribs usedfor storing ear corn and like produce which will not readily flow through a single bottom outlet. The wall panels 6, while individually removable, are not adapted.

for this purpose, since they preferably extend, the full height of the side wall 4. Accordingly, it is proposed to adapt the crib, for use as a corn drying crib by providing, between a pair of adjoining wall panels, an access opening 22 extending thefull height of thelside wall and closable by a plurality of, superposed gates or gate panels 23, eachcovering a particular portion or level of the crib. These gate panels are, each wall panels in miniature, differing; therefrom only in outside dimensions, and formed of. like side rails 24, connecting bands 25 and mesh 26. The gate panels are bolted to the adjoining wall panels through'the normally disposed flanges 11 of the side rails 9ofthe latter, with the crimped ends of the transverse bars or strands 27 of the mesh 26 of each gate panel lapping the contiguous crimped ends of the transverse rods 14 ofthe adjoining wall panel to provide the same resilient interlock therebetween. To afford the necessary lateral strength in the clamped structure after one or more of the gate panels have been removed, the wall panels adjoining the. access opening 22 are connected. thereacross by tie 4. bars or braces 28 which are spaced longitudinally or vertically of the opening to accommodate the gate panel's therebetween.

It has been mentioned that each gate panel is a wall panel in miniature. In practice, it will be found advantageous for the gate panels to be slightly less than half as wide as the wall panels. By maintaining this size relationship, it is feasible to cut the eight gate panels required for two cribs, such as that illustrated, from a single sheet of wall panel mesh, thereby enabling the mesh sheets to be procuredin a standard size and reducing waste to a minimum.

From the above detailed description, it will be apparent that there has been provided an improved corn crib of mesh panel construction in which the mesh is eltectively interlocked with the supporting members without fixed attachment and the panels, when connected together, form a self-sustainingside wall, the mesh interlock, while illustrated as applied to a corn drying crib, being of wide application in mesh panel construction. It should: be understood that the described and disclosed embodiment is merely exemplary of the invention and that all modifications are intended to be included which do not depart either from the spirit of the invention or the scope of the appended claims.
