To all whom it may concern..-

Be it known that I, EDWARD O. EA Is, a

citizen of the United States, residingat ".lo- .ledo, Lucas county, Ohio, have invented-certain new and useful Improvements in :Metal- 'li'c Grain-Storage Buildings,'of which'the fol lowing is a specification.-

In the storage of grain in buildings in which the walls and bins are constructed of sheet is exposed to atemperature lower than that metal, the following difficulties are encountered: First, when a bin is filled with grain and one or more of its walls is an outside wall,

or a partition wall adjoining an empty bin, thewallthus subjected to strai-n from one side only' will become distorted,'unless themetal is veryheavy, which entails undue weight and expense in construction; second, when the exterior of the metal wall of abin within the bin, moisture will be condensedupon the inner surface of the exposed wall, and the contained grain next to the chilled surface will become wet and damaged. I

My invention relates to and its object is toprovide a method of construction for metallic grain storage buildings which shall overcome the difiiculties above pointed out. 1 I attain these objects bymeans' of the construction and arrangement of parts hereinafter de 30 scribed, and shown and illust'rateddn, the accompanying drawings, made part hereof, in which V Figure 1, isa plan section of a sheet metal bin constructed according to my method; Fig.

- as shown in Figr 1, .though I doQnot limit my invention to this form of bin; In the drawings, the walls of the building and of the bins secured in close conjunction at their vertical edges, bymeans of bolts or rivets, as at b b,

v and curved away from each other so that in horizontal section the two sheets or shells,

present two equal arcs of a circle, reversed to 7 each other and having a common chord. The

sheets a are held rigidly in place and'secure against spreading or-collapse by means of braces,c o, securely bolted or'riveted to and between'the sheets a. In the angles .of the walls or bins are vertical angle-irons d columns built up of angle-irons and-inclosing sectors, e e e' and to projecting lips or flanges of these angle-irons or columns the vertical edgesof the walls, a, are secured as above indicated. The sheets a a may be corrugated or fluted to give them additional strength and rig idity, as in Fig, 3. The interiorsheets'of I the exterior walls may be finely perforated,

as shown in Figs. 2 and 3, so that the temperature of the air space between the double walls and thegrain next the inner wall shall be about thesame, thuspreventing condensation on the inside sheet even when moisture is condensed on the interior of the'ontside sheet. 1 I

The advantages of the.construc'tion here shown are, first, the great strength of the walls, both under tension and'com-pression, in proportion to'the weight of metal used; second, the spaces between the curved walls (which may be .either for dead air, or be packed with mineral wool, or other non-conducting niater ial) tend to prevent, by sudden changes of temperature, condensation and injury to ;the contents of the bins, as when the exterior walls are subjected to an extreme change of weather, or -when a bin contains warm grain and an adjoining bin is then filled with cold grainr What I claim as my invention, and desire I to secure by Letters Patent, is'- 1'. A metallic grain storage building, having the walls and partitions thereof composed of oppositely curved sheets of metal suitably secured together at their vertical meeting edges, substantially as shown and described, for the purpose specified.

2. A metallic grain storage building, having the walls and partitions thereof consisting of oppositely curved sheets of metal suitably secured to and in combination with vertical columns or angle-irons, in the angles of said building or the bins thereof, substantially as shown and described, for the purpose spool-- fied. I

3. A metallic grain storage building, having the bins having walls composed of oppositely curved plates meeting at their vertical edges, sitely curved sheets of metal suitably secured IO in combination with columns or angle-irons together at their vertical meeting edges, the in the angles of said bins, and braces in the inner wall being perforated, substantially as spaces between said curved walls rigidly seshown and described, for the purpose specicured to and connecting said walls, substanfied.

tially as shown and described, for the pur- EDWARDO. FALLIS. pose specified. \Vitnesses:
