s'moRAeE BIN.

Application alga April 2, 1925. serial No. 20,042.

My invent-ion relatesyto storage bins used for holding large quantities of heavy mate-l rial such as coal, "iron orelor the like, and such as, for example, are shown and described'in U. S. Patents Numbers 1,388,482 and 1,338,488 issued to:` me -April 27th, 1920.

In a bin such as is yshown in either of'said patents, the bottom kportion thereof is apro.-

vided with a plurality of reinforcing or stifi0 vide the storage space in such portion into a plurality of laterally arranged compartments. These partitions l have found serve as obstructions which frequently cause the contents of the bin to'form fixed arches in and over. the said compartments, and impede or'stop: the required downward flow of the material, when it is desired to discharge same by gravity from the bottom of the bin.

The object of mypresent invent-ion is to' provide abin structure in which said arching and consequent obstruction to fiow of material by gravity,'is eliminated, and may bve-applied to either the flexible-sided type of bin shown in said patents, Qorfthe rigidsided type of bins which is sometimes employed.

- his object I attainlby providing reinforcing or stiii'ening means for thebottom. portion of the bin of, such a character as will not include said previously described partitions and hence their attendant undesirableeitect. ,I This I accomplishfby securing exteriorly located stiilening means to thebottom portionfof the bin, which are so placed as to counteract the'tendency of the 'front and rear walls of such portion,'to bulge outwardly.

- The annex'edldrawings and the 'following description set orth'in detail certain meansrv embodying my invention, the disclosed means, however, constituting but' one of the ifening diaphragms or partitions which "diand upon a` some- Fig. 2, and viewed in the direction indicated bythe arrows.

Fig. 8 represents a section taken upon the plane indicated by line -VIII-VIIL Fig. 7. Fig.` 9 represents an end elevation of such modiiied form, of bin bottom.

My present'invention, inthe form illustrated bly Figs. 1 to G inclusive, is shown to be applied to the suspended 'flexible-sided type of bin shown in my above-mentioned patents, and in which the front and rear walls converge downwardly as'shown, and \1vhi1ch is provided with'the verticalend walls The front wall consists of a main or upper portion 2 anda bottom portion 3. The lat-k ter terminates a distance above the lower end of the bin to form a longitudinal rectanguiar discharge opening` running the entire length between the twoendv walls 1-l, as shown in Figs. l, 2 and 4. This opening is vcontrolled by a multiplicity of gates 4 laterally juxtaposed as will vbe yhereinafter urvther described. f t

Theback wall consists of a main or upper portion 5 and a bottom portion 6.-

. VThat portion of the end walls 1-1 which formsfthe end walls of the bottom portion of th'ebin, extends beyond the front and rearl walls of such portion as shown in Fig. 8. For the purposes of convenience and assemblythese end wall portionsare made of separate plates .7-7 alined with the lower ends of the main end plates 8 8 by means of riveted flat bars 9-9 as shown in Figs. 2 and3.

Extending between the end plates 7-7,

' upon thel outside of the front and back walls and secured respectively thereto by means ofangles 10-10, lare two horizontal supi ifo porting beams 10-10, of -beam section preferably, the webs of which extend at right angles to said walls, as shown in Figs. 3 and ll. l

The upper part of both the rear and front extensions of the end plates 7'-7 arev made of a width substantially equal to the depth .0f the beams 10'-10.

Also for convenience of assembly and repair, the

bottom wall portions

3 and 6 are each made of a separate plate, the lower ends of

plates

2 and 5 being secured to the upper part of the inner flanges 11 11 of the beams 10-10, and the upper ends of the

plates

3 and 6 being secured to the lower part vof such flanges by means such as the rivets shown, Figs. 2 and 3. 'y l Intermediately of the gates 4l (betwee each adjacent pair as illustra-ted) are a plurality 4of rtensionV members 12,'made of plate and in contact with the .front plate 3. Each of these members is of a shape and size similar to that of the extended portion of the end plates 7-7,'on the front of the bin, and has its upper end secured to the lower side of the front beam 10 by means of suitable angles 12-12, Fig. l.

The front plate 3 may also be secured to the members 12 by means of angles 3, asv

shown in Figs. 2 and 4.

Upon the lower end portion of the extenn sion of end plates 7-4-7 and the member 12, are secured longitudinally alined brackets 13, which support a rod 1li upon which the gates 4l; are pivotally mounted, as shown in Figs. '2 and 3. Each gate may be separately actuated through the medium of a suitable handle Ll attached thereto.

Each member 12 has its lower rear end portion extending backwardly through a slot 15, Figs. 5 and 6, cut in the bottom of the back plate 6, and each such rearwardly projecting portion of said members, is secured to the bottom of a rear tension member 16, of channel section, by meansv of an angle 17, Fig. 6.

'These members 16 lie against the .rear` plate 6 and each has its upper vend secured to the lower side ofthe rear supporting beam 10 by means ofl angles 18, Figs. 4 and 5.

The lower extremity of the bottom portion of the bin is reinforced by a horizontal angle bar 19 secured to the lower end of the rear plate 6 and to the channel member 16, bysmeans of angles 20, Figs. i and 5, the lower ends of members 12 ybeing out out for that purpose as shown.

It will be seen from the above described arrangement that each connected set of tension members 'l2 and 16 forms a. saddle or sling which is supported at its upper end by the two beams,l0-10, the latter being supported by the upper part of the bin,

i such

slings reinforcing thetwoplates

2 and 6 and counteracting their. tendency to bulge outwardly when the force due to theweight of the load in the bin, is applied thereto. These reinforcing members being, as described, located entirely upon the outside, the i nnerastora'ge-spaceofl the bottom portion of the bin is free andunobstructed so that the arching previously referred to is eliminated or at leastminimized.

inventionv as applied to a bin of the suspended type and -in which the discharge openings are placed centrally at the bottom. ln this form the front and back walls7 3 and G respectively, of the bott-om portion are each yreinforced by longitudinal horifl zontal -beamsflQl, the uppermost oflwhich,

21, are secured to the lowerend-portion of the main front andback walls, 2 and 5`re`- spectively, the en'dwalls-? being alined with the end walls 1 1, as in the first described structure.

As shown, theseAI-beamsV are allsecured to the exterior of

walls

3 and 6 and their ends secured to the end-,walls 7-7, by means of suitable angles 22, said end walls being extended front and rear for that purpose, as shown in Fig. 9. l

This modified form, therefore, has its front and rear walls exterior-ly reinforced to prevent them from bulging outwardly, but the reinforcing means are not suspended or of sling form as inthe first-described form of my invention. it will also be apparent to those skilled in the art, that the described sling method of reinforcement may be applied to a bin having its discharge openings centrally placed. Fiitlier type of reinforcement may be used in connection with .a bin of the form shown in Figs.,71 to 9, but the sling-type of reinforcement is particularly ,suitable to the type ofibin, shown in Figs. -11 to 6, and "in which the openings yare in the, side rather than centrally at the. bottom, allas will be understood by those familiar Vwith the art. What I claim is: j 1. A storage bin formed with an upper portion and a rigid bottom portion =having front and rear walls, and external rein-force ing means for saidfrontandrear walls suspended from said upper portion. n

2. A storage Vbin comprising an l'upper portion having flexible, suspended front and rear walls, anda rigid bottom portion having front and rear walls, and means suspended from ysaid bin land adapted to veX- Figs'7, 8 fand`9 illustrate a feature of my iso Y the front and rear walls of said bottom porrear walls, said sling acting as a stiffening member for the front and'rear walls of the bottom portion and intermediately of the end vwalls thereof.

5.. A storage bin having .anV upper portion and a bottom portion including two end walls, front and rear walls, and amultiplicity of slings supported by the upper portion oi the bin, located upon the outside of said bottom portion and supporting the 'said front and rear walls. y y

6. A storage bin having main end, front and rear walls and a bottom portion having end, front and rear walls in continuation of said main walls; front and rear longitudinal members secured respectively to the bottom of the said main front and rear walls and having the tops respectively of said bottom front and rear walls secured thereto; and a sling hung from said longitudinal members and supporting the front and rear'walls of said bottom portion intermediately of its ends.

7. A storage bin having main end, front and rear walls and a bottom portion having end, front and rear walls; two longitudinal members located at' the back andv front respectively of the bin and'having their ends secured to the end walls of thebottom portion of the bin and being also secured to the bottoms-of the main front and rear walls; the upper ends of the front and rear walls of the bottom portion of `the bin being secured to said members; and a sling hung from said members supporting'the front and back walls of said bottom portion intermediately of the ends thereof.

8. A storage bin of the suspended type comprising end, front and rear walls forming upper and lower. portions, said bin being provided with means for externally rein oroing the lower portion throughout its vertical length; such means being suspended from the upper portion of said bin.

9. A storage bin of the vsuspended type comprising end, front and rear walls form ling upper and lower portions, said bin` hav# ing a rectangular horizontal crosssection and said bottom portion being externally reinforced to make it rigid.

l0. .AA storage bin of the suspended type comprising end, front and rear walls forming upper and lower portions, said bin having a rectangular horizontal cross-section and having its vbottom4 portion yprovided with externally placed reinforement; the

latter being suspended yfrom the front and rear walls of said upper portion.
