To all ila/tom tmc/y concern Y Be it known that I JOHN E. ALLsTEADT v 3 l 3 c itizenfof the United `States, residing at y Hastings in the coiiiity of Adams and State of-Nebraska, have invented certain new and useful Improvements in Vh etallic Storage- Y Bins, of which the following is ayspecication. vMy,invention vrelates to metallic structiires, and

bins.

Other objects will appear in thecourse of the following description. .r My inventionis illustrated in the accom'- panyiiig drawings, whereing- Figure lis a vertical. Central section 'of a Abin constructed in accordancewith' my in?,

Referring to Figs; y1 and2 it kv villbe seen that the bin iscircularin cross-'section and comprises upstanding sfide walls, a conical roof, made in sections, and a bottom made in sections. The sides ofthe bin 'are formedof sheets of `metal 2, the s he'etsfbeing fastened to lap` over the upper edgeoifthe next adj acentseetion 2. As shown, the bin is constructed of three tiers of 4metallic sections, tliefiipper 4tier being ,designated U2?, the next tier belQW .being designated@ and the third or lowestte being' designate/'C192 It willfof course, be nnderstood that any ninnber ofsections orlteis may be i ised, depending upon ,the heghtef 'the structure- Theeveriappins margine ef Qnesetfin or' eislieldto Athe upper niarginQ thenext .section being designated 7.

adjacent section by means of bolts or rivets 5, disposed at suitable intervals and for the purpose of supporting one tier upon another until the sections have been riveted or bolted to each other bythe bolts 5, I provide upon the inside face of the upper section at the lower margin thereof the downwardly projecting cleats 5a which are preferably made of metal. These cleats extend downward below the lower edge of' the upper section and are slightly curved to conform to the bead 3 of the upper section and then extend downward and outward. lll/*hen an upper section is placed upon the lower sections these cleats act to support the superjacent section While the rivets or bolts are being put in place. This permits one man to place the sectionsone upon another and to rivet or bolt them together without the necessity of' having the sheets otherwise supported while the rivets or bolts are being put in place. This construction adds very much to the ease with which the parts may be assembled. The uppermost tier of sections designated 2, is braced, and held rigidly to a circular fo in by a sectional angle iron, the vertica flange of each angle iron extending downward on the inside of the sheet metal side section and horizontal flange' extending outward over the top edge of the section. There may be as many sections of the angle-iron 6 as required, but preferably there are two, each semi-circular in form and of such site that the adjacent extremities of the angle irons overlap so that the angle'irons may be bolted or riveted to each other as well as to the upper margin of the wall of the bin. The bottom of the bin is made in a plurality vof sections, preferably two sections, each of these., sections being segmental in form, each Each section of the floor or bottom may be made of as many pieces or sheets of metal as may be necessary, the sheets being riveted to each other and preferably formed with interlocking joints as at S. The outer margin of each section 7 is reinforced by a seinicircular angle iron section designated 9 which is riveted or bolted to the metal of the section 7- and the inner or diametrical margins of each section 7 are reinforced 'by means of ane'le irons l0 riveted or bolted to the sections. rlhe angle irons 9 have a horizontal flange and a downwardly extending vertical flange and the angle irons l0 have their vertical flanges extending upward. When the sections of the bottom or floor are Vplaced together the vertical flanges of the angle irons l0 abut against each other and the sections are held to each other by means of bolts passing through these verti.

cal flanges. A packing may be disposed between these vertical flanges, if desired. These angle irons 10 therefore not only act to lrevide means'whereby the two sections of a plurality of segmental sections, the sections being detachably connected or jointed lto each other. Each section may be formed of a. plurality of plates or sheets of sheet metal riveted or jointed to each other. rlhe sections of the roof are designated ll and as illustrated are four in number, though of course, more or less of the sections may be used. Each section is formed on one side edge with an upwardl i projecting flange l2 and upon the opposie side edge with upwardly,extending bead 13 approximate y rectangular in cross-section, the upwardly extending flange l2 of one section being adapted to hook under the downwardly extending margin le of this bead, as illustrated clearly in Fig. i. rllhe sections are further connected to each other by means of latching members l5 disposed on one section adjacent the joint thereof, extending across said joint and engaging beneath straps 1G riveted to the adjacent margin of the section, the middle of the strap i6 being open so as to permit the insertion of the end of the latching member beneath the strap 1G. The extremity of the latching member l5 is then turned over as at 17 upon the strap 16, thus holding one section firmlj-,f l

locked to the next adjacent sectionand preventing any disengagement of the joint between the sections. Art the center of the roof the sections `l1 are cut-away to provide an opening 18 for the Ventilating flue. Extending radially from this central opening are a plurality of rafters 19, each rafter, as shown. in Fig. l, being angular in cross section. These rafters may be made of relatively heavy sheet inetal or of relatively heavy angle iron. Each rafterhas an upwardly projecting flange and a horizontally projecting flange. VEach rafter is disposed in the joint between two adjacent sections ll,

the horizontal flange of the rafter being disposed beneath the margin of the section ll whichis providedY with the upwardly extending flange l2, while the vertical flange 20 of the rafter is disposed between the flange l2 and the side of the bead 13, as shown clearly in Fig. il. rlhe inner end of each rafter is bolted or otherwise attached to a cap-plate 21, as shown clearly in l? ig. 2, bolts 22 passing through the horizontal flanges of the rafters and through said capplate.V The cap-plate is square in plan and concavo convex and is formed with a central opening 23. The cap-plate is so arranged that the corners of the plate are in line with the rafters so that the bolts 22 will (ffl pass through vrelatively wide portions of Furthermore by making vthe plate many.- sided Vand so arranging the rafters with relation to the plate that the rafters' are disposed at the projecting corners of the plate,

a larger bearing will be secured for the rafters on the plate than if the plate were round or circular. Each raftei adjacent its cuter end is formed with a downwardly projecting perforated ear 24, preferably formed by slitting the rafter at its outer end at the junction of the vertical flange with the horizontal flange and bending down the extremity of the horizontal flange. rlhe latches 15, previously referred to, each pass beneath ythe horizontal flange of .the corresponding rafter,= as shown clearly in Fig. 2, thus not only locking the roof sections to each other at the joints but locking the rafters and roof sectionstogether. It will be seen lthat this construction provides for a very easy assembling of the rafters with the roof sections and an easy means of fastening the roof sections together to form a complete roof. Furthermore this arrangement permits the ready removal ofthe roof sections from the rafters-where vrepairs or replacement are required. Each Vroof section is provided at one or more points with downwardly extending ears 25, these ears being vertically slotted as at 26 and these ears 25 with the downwardly turned ears 24 on the rafters are adapted to be bolted vor otherwise secured to the reinforcing angleiron G at the top of the side wall of the bin, as shown clearly in Fig. 1. Preferably, this engagement of the lugs 24 and-26 to the angle iron will be secured by mea-ns of bolts passing through the angle iron and through; the perforations or slots in the ears 24ror 25.

metal plates forming the roof sections.

One of the roof sections is preferably provided with an opening closed by a sliding door 27, this opening being used for the purpose of filling the bin. To this-end one of the sections is cut away to form the doorthe guides thus formed.` lThis door is ,pro- -vided with upwardly'projecting flanges 31 which engage beneath the overturned beads 28 and the side margins of the door rest upon the strips 29. It willthus be seen that By slotting the `ears V25 provision is made for `any buckling or distortion of the| f a perfectly weather proof joint is provided between thereof section and the sliding door and that whenthe door'is closed it is entirely protected from the -entrance of water around the edges Yof the door, the upper end `of-thedoor --projecting into the space-between 'thestrip 30 and thesuperposedlmargin yof the door opening. T he door may be provided with any suitable handle whereby it may bei opened and with any suitable locking means. Y

Inorder tof brace the structure against overturning byy high windsl connect thereto the guy-wires 32, as shown in Fig. 2. Pref- I erably, these guy-wires are attached to therafters 19 and to this end the outer en'ds of the rafters areprovided with pivoted loops 33, as shown inf-Fig. 2 to which the inner ends of the guy-wires are connected. Thesel loops beingpivoted may b e shifted into anyy desired angular relation to the rafters, thusV permitting the guy-wires l to take any desired angular relation. and be attached atany suitable distance from the bin, as circum-V stances may require. It is to benoted that these loops 33 are disposed exteriorly of the lugs 24 and 25 so that the loops will be exterior to the side wall of the bin. It willv also be noted from Fig. l that the onterinargin of theroof projects a considerable distance beyond the side walls, thus preventing lthe entrance of rain. The lugs 24L'and 25V support` the roof sections and permit the roof sections to be so adjusted that a ventilating space may be left between the angle Viron 6 and the roof for the free admission of air into the upper portion of thebin.

In order to provide for a proper ventilation of grain contained within the binl so that any moisture in the grain may be carried off, I provide the Ventilating iue designated 35, as shown inFig.v 1. At its upper end the flue projects through the opening 23y in the plate 21 and' through the open- ,ing 18 in the roof,thisv openingl being cen- Atral. As illustrated in Fig. 1, an open ended l thimble 37 is riveted or otherwise attached to the sheet metal formingthe floor sections 7, this vthimble having a1 flange to permit ofv this attachment. A sleeve 36 extends partly into this thimble and partly into the lower end of the low-er section of the' flue and holds the lower end of the flue in registry Vwith the opening and securely but detachably connected to the thimble 37 ,l do not wish to be limited to 'this manner of connecting the lower end of the flue 35`to the floor Vor bottom section 7 as itgwill be obvious that Vother means might be arranged for supportingl the lower end of the flue and making a close jointbetween'the Vfloor section and the flue and preventing ingress of mice ory rats into the bin.V The upper end of the flue, as

before stated, passesup through the opening 18 and projects slightly above the roof. f The downward and outward a disk 41, and supported above this disk 4-1 on brackets 43, and in spaced relation thereto isthe conical cap 42. lt will be seen that the angle of the disk 41 is more acute'tlian the angle of the roof and hence that the margin of the disk 41 will rest on and fit snugly against the roof' and thus prevent the entrance of rain into the openingl 18. The Ventilating flue 35 is constructed of sheet metal and may bein one piece or inV sections,`as desired. It is provided along its length with openings permitting the outward passage of `air but so arranged as to prevent the passage of grain.

ln order to connect the side wall of the bin to the bottom thereof, the lower margin of the lowest tier l2C of the metallic sections forming Athe wall is bent underneath the vertical flange of the angle-iron 9 andthen bent upward inside this flange as at 52. By

this construction it will be seen that the lower edgel of the side walll is caused to overlap the downwardly turned margin 7u of the metal forming the floor section 7, thus entirely closing the oint between the meta-l of the floor section and the angle iron and forming a joint which will not permit the entrance of insects or small animals of any kind. Of course, the inwardly turned lower margin of the side wall may be riveted or bolted to the vertical flange or angle iron 9, but I have not found that this is necessary in practice.

l/Vhilc the door 27 is Yfor the purpose ofl loading the bin or permitting access'to the upper portion thereof l also provide a loading door opening 53, as shown in Fig. 1. The margin of this door opening is strengthened by angle irons 54 having outwardly extending flanges forming the door, frame. The outwardly extending flanges of the upper and lower angle irons 54a are laterally extended at one side to form a support for the pivots upon which the door 55 is hung. rlhis door 55 may be ma de of sheet metal provided at its margins with inwardly turned flanges 5G which are so disposed that when the door is closed the kflanges will fit over and have snugv engagement with the outwardly projecting flanges. of the angle irons 54 and 54u. I rlhe upper and lower flanges 56 are extended beyond the inside margin of the door for engagement with the ears formed bythe extensions of the flanges 54a and are pivoted to these extensions kby means of bolts 57 or other suitable pintles. The door is provided with any suitable hasp 58 engaging with the keeper 59 on the body of the bin and permitting the door t0 be locked when closed. Interiorly of the door opening 53 there is attachedto the wall of the bin the plate GOhaving inwardly inclined Side edges riveted to the wall of the bin, this plate being provided with the cen- 70 tral opening 60@L closed by'a. sliding'door G0", and having an integral grain cap G1, as shown in Fig. 1. Below the opening 53 the side wall of the bin is formed with a discharge opening closedrby a door 62. The door 'opening is relatively long and as illustrated, extends across the'two tiers 2b and 2U, the lower portion of the door opening being disposed only about two inches above the floor section 7. This door opening is framed on the exterior by angle irons G3 and G4 which are riveted to the sheet metal forming the wall of the bin, these angle irons having outwardly projecting flanges. The angle irons 64 are extended laterally at one end to form ears 65., rlhedoor 62 is also framed by: outwardly projecting fianges GG and G7 so'fdisposed that when the door is closed the flanges will have snug engagement with the outwardly projecting flanges of the angle irons G3 and 64 and the angle irons @Bare extended laterally to form ears 68 through which pintle bolts 69 pass. The door is provided with a hasp 70 adapted to engage with the keeper 7l whereby the door may be locked to its closed position. Above the door frame is a weather cap 72 which projects out far enough to extend entirely beyond the upper angle iron 64and beyond the door when the door is closed, thus preventing rain from dripping down upon the door and possibly entering the bin in this manner.

In orderv to providey for the removal of grain from-the bin by means of a spout so that when sufi'icient grain is in the bin the grain may be conducted to a wagon and allowed to run by gravity thereinto,'l mount upon the inside face of the bin the casing 73, as illustrated in Fie'. 4. vThis casing consists of a sheet of metal 74 extending approximately parallel to the wall of the bin, the side margins of the sheet being inwardly bentas at 75 and then laterally bent as at 7G and riveted to the wall 2 by rivets 77. rlhe sheet metal 74 forming the back of the casing 73 is formed with a central opening 7 8 and on each side of this opening there are provided guides 81 'between which slides a door 82 having a handle 83 whereby it may be readily raised and lowered. This door 82 constitutes a cut-oli" which permits a regulated quantity of grain to pass through the opening 78.y The lower edge of this cut-off when the cut-oftn is closed, abuts against a strip 85 (see Fig. 1) which extends across the outer face of the plate 74 at the bottom j of the door opening.A This strip 85 is out- Awardly flared along its upper edge so as to ginof the strip andthe 74, andthe lower margin of the strip is outwardly bent to extend beneath a pivoted chute or YVspout 86, when the latter isopen. AThis chute or vspoutis also made of sheet metal and has upwardly extending sides 87 formed Vattheir upper ends with'laterallydeflected ears 88,

these earsbeing pierced for the receptionofl the pivot pins 89 .projecting inwardlyl `from brackets 90 riveted' Orotherwise securedto the Vouter face ofthe lplate l74, as shown clearlyin Figs. 2 and 4. The space between Y the plate 7 4 and the outer wall ofthe -bin is Vof vsufficient depth to permit the spout to Vbe rest'against the inner face of the bin wall.

The grain cap is preferably formed integral with the plate 74.

Immediately beneath the lower edge `of the plate 74 there is disposed a downwardly .and y inwardly extending plate 91 lwhich forms the top of a passage 92. This plate 91 is downwardly bent` at the sides as at 93 and rests upon the bottom or floor 7 of the bin. The' downwardly and inwardly in' clined top y91"of this`,passage 92 will cause.

any grain which may be resting `upon this top to slide off into the bottom of the bin,

'when the level of the grain in the'bin is V end of the spout reduced below the level of this 'wall 91. At the same time the passage 92 permits the grain in the lower portion of the bintobe shoveled out and discharged through this passage 92 after thelevel ofthe grain has fallen below the level of the discharge opening which is closed by the slide l82. While ordinarily, when the bin is full, grain will be discharged through the opening closed by the slide 82 or cut-off, yet it is always possible to enter the passage 92 and shovel the grain out from the bottomof the bm, as

the roof of this passage will support any grain and prevent the filling up of this passage with grain. The strip 85 is for the purpose of preventing grain from leaking through the Vjoint between the upper rear 86 or chute and the outer face of the plate 7 4 and thus preventing the lodgment of grain upon the outer projecting end of the roof 91 of the passage.

In order to prevent the possible lodgment of grain in the joint between the side wall of the bin and the floor in a position where it is difficult to remove the grain I preferably attach to the inner face of the side wall a downwardly and .inwardly extending strip tends over the joint `'between thebo'ttom or suitable foun'dation, j a'ndfthisVv foundation,

may be so constructed asto permit the inl `gress of .air beneath thebin so that the ai-r Amay 'pass' up Athrough 'thecentral Ventilatingl flue. A 1I have @shown for lthis'purpose trans-vv verselyl extendingl wooden 'l sills :9 5 upon which the bin' rests,I these sills; being in turn supported uponsuitablelfoundation sills 96 or other suitable foundation, it beingdesigned to lift the structureV sufficiently from the ground to permit air to freely pass beneaththe structure. 1 v 7 While I have'shown in Fig. 41, a joint which I have found to Vbel particularly pracj tical andsuflicient for the purpose `of con- `necting'one tier of the sections forming-"the side wall'to the `next tier, I do not wishjto y be limited to this lasother formsof joint mightbe used.

yIn Fig. 6 I- show. another manner of connecting the adjacent sheets.l In this figure the sheet2a is lapped over the sheet 2b and a batten -102is attached tothe sheet 2EL by arivet 103. This batten is 'formed Vwith a folded margin 104 so astoformfthe batten of `three thicknesses at one end. Thel rivet 103 is passed through these three thicknesses.

VA socket isthus formed between thedownwardly extending portionof the hatten- 102 f and the adjacent face of the plate'2a within which the upper margin of the plate 2br is inserted. A bolt 106'is; passed through the plates 2a, 2P and the downwardly extending margin of the batten V 1021. l

-v'Ihe angle irons 63 are perforated atintervals to permit a brace 103 to be trans' versely i through which the spout 86 operates and positioned f across. the `.opening thus hold the spout-in its raised position and Y prevent any unauthorized tampering with the cut-olf slide 82.

As before remarked, this device is parn ticularly intended to be shipped in sections yand setup bythe purchaser at any desired location. It is for this reason that the parts are made of sheet metal so as to be light, and so formed asto be conveniently connected to each other. The bininay be set up in any suitable location and is readily transportable to some other location whenever desired. lVhen set up it is thoroughly strong and is proof against the inroads of rats, mice and insects. The grain is ordinarily discharged either into the receiving door yin the roof of the bin or into the upper door 53.' The upper door 53 is found particularly convenient for spouting the grain into the bin directly from a threshing machine. As the bin is filled, boards are disposed across the .opening so as to prevent" pressure of the grain from forcing the doors u of the bin.

When the bin is filled to capacity there will l/Vhen it is .desired to remove the contents.

of the bin the grain maybe discharged either throughthe opening controlled by the cut-olf S2 or through the passage 92, as desired. Irhave found the cut-offk and spout of great convenience in filling wagons from the bin and also for using the grain for feeding purposes, it being possible to allow a very small quantity of grain to pass out from the bin and then to close the slide again. It will be noted that when the door 62 is closed it is impossible fo-r stock to accidentally open the doorv and thus get at the grain within.

Vith reference to Fig. Vl it will be seen that the roof projects sufficiently beyond the side wall to prevent any possible entrance of rain and yet that the vroof may be so ad,- justed as to permit air to enter beneath the eaves and passinto the bin, as desired. It will further be seen that no rain can enter around the Ventilating flue because of the close contact between the margin of the plate 41 and the roof sections. The same care has beentaken in forming the joints o-f the roof sections and the joints between the roof sections and the doors to prevent any possible entrance of moisture or prevent the entrance of animals, and it is also obvious that insects or small animals cannot enter the'bin through the Ventilating flue inasmuch as the lower end of this iue is raised above the ground and further, inasmuch as the Hue is made of sheet metal.

My improved storage structure is simple, easily assembled, easily transportable,

and has been found 'vertical flange in contact with'the depending rim thereof, said body having its lower edge portion bent inward beneath the said depending rim and the vertical fiange of the angle iron, thence upward and against the inner face of the said vertical flange, with its upper edge' in contact with the horizontalflange of the angle iron.

2. A sheet metal structure comprising a body, a bottomr having a depending rim arranged in contact with the lower edge portion of the body, an angle iron disposed beneath the bottomv with its horizontal flange in contact with said rim thereof, said body having its lower edge portion bent inward beneath the said depending rim and the vertical flange of the angle iron, thence upward and against the inner face of the said vertical flange, with its upper edge in contact with thek horizontal iiange of the angle iron, and a metal strip attached at its upper edge to the body and having its lower edge portion bent inward to overhang the outer portion of the bottom and in contact therewith to confine the same upon the horizontal flange of the angle iron.

In testimony whereof I afliX my signature in presence of two witnesses.
