To all whomit may concerns Be it known thatI, GEORGE F. HURT, a

citizen of the United States, residin at New York city, in the county of New orkand 5 State of New York, have-invented certain 'new'and usefulylmpro'vements in Storage Buildings, of'which the following is a specification, reference being had therein to the accompanying drawing a This-invention is a novel storage building, and refers more especially to the structure and form of a building for storingan'd handlin by means of cranes'm'aterials in bulk, of

which fertilizers may be taken as an ex ample. Themainiobjects-of the invention are to afl'ord a storage. building which is economical of structure, ample'fin available storage s ace, well adapted for the opera tions of t e crane'and safe from liabilityto such injury asff'requently occurs tostorage buildi' s from the pressure of the stored m'ateria Other *and"further objects and advantages of the present invention will be made clear-"in the hereinafter following description of a building in which the present invention 'is embodied,- or will be apparent to those skilled inthe art, I

To the attainmentfof such objects and ad vantages the present 'inventioniconsists in the novel storage building and the novel features of structure, arrangement, and 'combination herein described or illustrated. In

the accompanyingdrawings forming a part hereof, the single, figure is a more or less 36 diagrammatic transverse section and elevation of a storage building, embodying the principles of thepresent invention.

It will be'und'erstood that the building maybe of any desired length, the length '40 being increased at will by the adding of units or sections, to each of which the present invention is vapplicable.

Referring tothe "drawings, the main columns 10 at the opposite sides of the buildmg may be multiplied longitudinally as far as desired, according to; the length of the building. Each longitudinal series of upright columns, suitably foundationed'at 9 inv the base or ground, constitutes *part of the to structural frame of the building, giving suportto the roof, walls and mechanical handng apparatus or crane. The columns are shown as supporting outer side walls 11. As will be explained, however, theseside walls or coverings, or the upright portions ll'off themfdo not extend entirely, tothe base,xbut

are supported uprightly in'elevatedflocation at the upper portion of. the longitudinalseries of columns, so'that the space between the lower ends of the columns is open; Ex

tending across from side to side are the roof trusses 12, with any suitable roofing and concomitants,-as may be desired.

At the eppositeinterior sides of the building are thelongitudinal beams or tracks 13, on whichrun the wheels at the ends 'of the' crane girder or bridge" 14. As a partpf the crane is indicated a carriage or trolley 15, which may slide or roll transversely'along the lengthof the girder 14, and from the carriage hangsthe bucket 16, which may be lowered and elevated, and opened 'and closed" in the usual manner. By the up and down,

the transverse, andthe longitudinal movements described, the bucket is capable of reachingevery portion ofthebuilding with the trifling exception hereafter noted. It reaches every point between the opposite up-.

right side-walls 11, and it will be observed that below theo'verhead crane the space be-' tween the side walls and longitudinal column lines is free and unobstructed for the;0pera-' tions of the crane. The columns have no interior diagonal braces obstructing the path of the crane, but are eifectiyely otherwise crane is to serve as an overhead co-nv'eyer, either for introducing the fertilizer or other material'in the form of. a pile or for'removing it, and the particularfform and'operation of theillustrated'conveyer are not herein claimed.

' The side walls'll may be of very cheap construction, "as they are merely protective and receive no strain. These are shown as terminating at a' polnt above the flooring,

whichis approximately half the height of v members or braces 22, extending from the columns 10 to the ground or exterior foundation 23, therefore operating to stiffen the upright columns, as well as supporting the Each vstiffened as will appear. The purpose oftheq W i I adjacent shed wall or covering 17. The shed extensions, as will be seen, receive at each side the"toe of the piled material. It is herein assumed that the piled-up material will'have at its sides a slope of approximately 45. For a substantially different slope or angle ofrepose of the material being stored, the extent of the sidewalls.

11 and the shape of the sheds 17 might be correspondinglyaltereda i By rough l1ne 18, I have indicated the 5 5 proximate form of the sides ofthe pile-of storedmaterial, which can be accommodated :in thedescribed stora e building, and by lQthe preferredform 0 the top of such pile, it. being shown truncated. In some. cases the ,pile might be continued to a central apex, as. indicated bythe dotted lines 20, but this would require the roof, the crane,

and therefore the building as a whole to be that extent higher, with relatively small gain of storage volume, disproportionate to i the added cost of the structure. I prefer the I building and the stored pile to be substantially as shown in full lines, this giving a substantially greater volume of storage for the cost of the structure than any building heretofore, known with which. I quainted. 1 v r i v In fact, the practical height of the stored pile is in many cases limited by the fact am acthat excessive height ives excessive pressure at the base of the p' e, which is known to be injurious to many materials. given height of pile, which may be designated 0;, the present invention gives the maximum volume of storage, especially in proportion to the amount and cost of the building structure itself. For the purposes of explanation the width of the building maybe; designated b,'and this. as shown is.

preferably approximately twice the height ofzthe pile of stored material, that is, b:2a. At least the. width is materially greater than the height of the pile, so that b the use of the extension sheds the pile will ave atrun crane itself.

cated .form.

The importance of the shed extension .17

will now be explained. Without these, and

assuming the side walls ll to, extendstraight to the ground, these being of. light and cheap construction wouldnot suflice to serve as a retaining wall. In other words, the material could not be piled up to. thefheight indi-v cated by the lines 18cv The dotted lines '21 indicate a triangle which is approximately 4 the maximum storage space that Would be available. 1 Under the assumed dimensions this would be tax?) cubic .feet per foot" of length ofuthe building. 'With such a building the only mode in which the storage volume .could be increased would be to re,-

place the side wallsll bysolidand expen.--

sively constructed retaining Walls. 'Many stored materials tend to expand laterally,

For a not merely from mechanical pressure, but from expansion within themass, or equivalent action. Fertilizer has been 'known to expand to such an extent as to cause walls to diverge, to the"permanentqinjury ofthe building. It is one of the advantages of the present invention that the necessarily heavy retaining'walls to avoid this, are Wholly dispensed with, and a structure .whi'chislight, inexpensive, or even temporary will adequatelyserve. it

By the employment of the shed A extension 17 this result isattained, because the material'may now be piledup to thepoint indicated by the lines 18, 19 and 18. This is .the' natural form. that .thewpiled material will take. The material extends outwardly. beyond the columns l0, and into the sheds 17, as. indicated. The pile 'beingof natural form, the sheds, and'in fact the side walls, are required to take no pressurewhatsoever.'

It will readily be seen that the storage volumesby the present invention .will be approximately @Xb cubic, feet. per foot of building length, that is, twice the volume available with an ,ordinary building in which the material is. piled,as indicated by the. dottedlinesQl. Moreover, this practlcally' double storage capacity is 'at relatively no additional expense, as the -shed, walls-l7 are cheap and easily. constructed, and they substantially merelyreplace the omitted lower portionsof the side walls 11, while the inclined frame members 22 of the shed effectively brace the columns,fenabling. the, latter to be of relativelyv light-weight. Moreover, every part of. the stored material will. be readilyfaccessibleto the crane buckets, with! the exception. of a portion of the material beneath the shed walls 17 ,1 and this is of very small proportionate amount, and easily madeaccessible by other-means. The increased volume accessible tothe crane,

it will. be noted, "is, afforded without any 0 increase whatsoever in the travel of. the

It will thus be seen that I have described,

portions supported by suchcolumns, one or ing open spaces between the lower ends of crane located above the pile'and arranged to operate longitudinally and laterally to give access to all points between the opposite side walls for introducing and removing material, and an external shed extension at the foot of one or both of the opposite side walls to receive the toe of the pile, consisting of inclined brace members extending from the said wall columns to the ground and an inclined shed covering adjacent said brace members.

2. A building for the storage and mechanical handling of bulk material, such as fertilizers, the same comprising, in combination: an overhead mechanical handling apparatus operating longitudinally and laterally within the building both to introduce terial, a structural frame giving support to the roof and to said material handling apboth of which terminate above the floor leavthe columns, an interior overhead bridge in the form of a pile and to remove the maparatus and including longitudinal series of foundationed upright columns, and constructed to give free unobstructed space for the full width between the column lines for the operation of'the material handling apparatus, and generally upright inclosing walls, at least one of the longitudinal inclosing walls having a substantially upright portion supported in elevated location upon the longitudinal column line and terminating substantially above the floor, and having its lower portion disposed exteriorly beyond the column line, extending outwardly and downwardly to form a longitudinal shed to receive the toe of the piled material, with a longitudinal series of foundationed frame members extending from the several columns outwardly and downwardly, supporting the shed wall and arranged to brace the column line.

In testimony whereof, I have afiixed my signature hereto. I
