3 I YEW Patented Apr. 21, 1953 [TED STATS 'LE'E'E' OFFICE The farmer who raises large quantities of grain is often confronted at harvest time with the problem of storage. The need for such storage may not continue indefinitely, so it is desirable to hold to a minimum the expense of providing bins or cribs for such purpose. The use of term porary and inexpensive storage facilities for surplus grain is an acceptable solution of the difficulty. Bins or cribs, to be satisfactory, must have sumcient rigidity to withstand the excessive pressures of large quantities of grain. Also, structures of this character must afford the maximum protection from weather in order to minimize grain deterioration.

The main objects of this invention, therefore, are to provide an improved form of rigid, weather-protecting storage structure in the nature of a bin or crib that especially is adapted for the protection of grain; to provide an improved structure of this kind which utilizes advantageously a fabricated stave construction which, when not erected, occupies butlittle space and is readily transportable from place to place; to provide an improved form and arrangement of a weather-protecting roof for grain bins or cribs of the kind noted; to provide an improved construction and arrangement of a door for such a bin or crib; and to provide a storage structure of this kind which is easily assembled and disassembled, as occasion may require, and which when disassembled is very compact and requires a very limited amount of space for its accommodation.

In the accompanying drawings:

Fig. 2 is a plan view thereof with parts of the roof covering successively cut away to more clearly indicate its complete formation;

tional view of the eave construction in which a modified form of hook is used to anchor the roof supports to the wall, the view being taken on line l-! of Fig. 6; and

Fig. 8 is an enlarged fragmentary detail in section, taken on line 88 of Fig. 6.

The improved form of storage structure herein shown, and embodying this invention, is made up either of one or two sections A and 13 having annular walls comprising strips of wire-connected staves. The ends of the upper section B are directly connected together (see Fig. l), or they may be anchored to a doorway frame D, as in the case of the lower wall section A where side ingress into and egress from the enclosure is desired. Over the top of one or the other of the wall sections A or B, depending upon whether the structure consists of one or two tiers, is spread and anchored a weather-protecting roof B.

Each wall section comprises a plurality of staves It held in parallel relationship by transverse supporting wire bands l5 to which the staves are secured by attaching wires 16. As will be noted from Figs. 1-5, the staves in the bin structure are disposed closely adjacent each other, separated only by a thickness sufficient to accommodate easily a single convolution of the attaching wire it around the supporting wire It (Figs. 1 and 4); in the crib structure of Figs. 6-8 the spacing is somewhat greater to accomiho date several convolutions of the attaching wire it for winding around the supporting wire l5. When the storage structure comprises two wall sections, as shown in Fig. 1, the upper section B may be supported On the lower section A as by means of S-hooks ll. V

The doorway frame D comprises a pair of opposed channel bars 58 connected together top and bottom by cross pieces l9 and supporting angle brackets 2i? whereto are connected the ends of the fencing section forming the wall A. As shown in Fig. 5, the ends of this section of fencing are secured to angle brackets 28 by having bolts extend through the end staves I l and having the supporting wire l5 wound therearound. U- shaped hooks 22 are bonded to the inner upper cross piece as (see Fig. 4) to receive the ends of the staves of the upper wall section B and coact with the S-hooks It for effectively supporting the upper wall section on the lower wall section A. A plurality of panels 23 of wood or the like slide in and out of the channel bars it to provide a closure for the doorway frame D.

The roof R comprises a plurality of truss rods, 24 over which is laid. a covering of weather proofed fabric or paper material 25 and a wire netting 26 the perimetrical portion of which is secured to the wall section A (or B) by a bonding wire 21. The truss rods 24 which may be arcuate shaped are disposed across the wall section A (or B) slightly off-center and extended therebeyond to be doubled back and hooked thereto to form an eave around the supporting Wall section. Near the center of the structure there are numerous points of crossing of the truss rods where tie wires 28 may be applied thereto. The hooked ends 29 may be either vertically disposed and downwardly open, as shown in Fig. 3, or horizontally disposed and outwardly open, as shown in Fig. 7. In the one case (the bin) the rods 24 rest upon the upper ends of the staves l4, and in the other (the crib) the rods are anchored to the supporting wire i at points between the staves.

At least two tie wires 39 may be employed to hold the truss rods 24 is proper spaced relationship at their eave ends and provide support for the roof covering 25 between the rods 24. The roof covering may comprise either a treated paper or fabric 25 over which is laid a wire netting 2B. When paper is used it is preferably a heavy kraft paper treated with asphalt; if fabric, it is preferably a mildew-resisting duck treated with a water-proofing compound and formed with reinforcing grommets.

The wire netting 2B, of course, may be of almost any light construction. However, what is commonly known as chicken wire fencing has been found most suitable. It is light, open mesh, and forms a sufficient protection to the layer of material beneath it, particularly if it is paper.

As shown, the roof covering 25 may extend down below the eaves formed by the doubling back of the the truss rods 24. The perimetrical portion of the roof covering is drawn in under the caves and bound by a wire 27 to the wall section A (or B).

With equipment of this kind a grain storage bin or crib may be quickly set up with the expenditure of very little time and labor. Moreover, it may be set up at almost any point, where the grain is harvested or near a shipping point. When the structure has served its purpose it may be disassembled and removed with equal facility. The fencing and the roof covering may be rolled up and the truss rods stacked. Thus a minimum space is required for storing the equipment until it is again needed for forming a storage bin or crib.

Various other modifications in the details of the structure and arrangement of the parts thereof may be resorted to within the spirit and coverage of the appended claims.
