'6 Claims. (01. 211-131") This invention relates to revolving :bins'of the kind in which bin-units are providedv one above another upon a common suppor'tingshaft, each with capacity for rotation relativeto the. shaft and to the others.

Bins of .this character havecom-monly been madein the past exclusively of metal. It has recently become desirable because of war cenditions: to find substitutes for metal, and to devise new structures employing. non-,metaliic materials wherever possible as substitutes forold structures inwhich metals were freely used. Theelimination of metal in the principal parts of a bin unit presents new problems, particularly in. the matter of providing; anorganization of adequate-strength and. rigidity for performing theintended service.

It isthe primary object of the present inven tion to provide a revolving. bin. unitin which all the parts, exclusive of joining hardware and bear ingmembers, may be formed of. any suitable non:-

metallic material such, for example, aswood.

Although the present invention is. primarily in.- tended to enable the use of metal to be avoided to .a. large extent, it isalso useful in: a structure in which there is no restriction upon theuse ofmetal.

Other objects and advantages will hereinafter appear.

In the drawings forming. part ofthis specifi cation F g. 1 is a view in elevation; broken awayin'. termeoliate its height, showing a. revolving bin in which features of the invention are embodied;

Fig. 2 is a fragmentary plan view of the structure illustrated in Fig. 1 buton a largerseale thanFig.1;' i

Fig. 3 is a fragmentary detailplan view illustrating particularly the connection of. a permanent divider to the floor member of: abin unit;

Fig. 4 is a fragmentary view in sectional elevation, and partly broken away for compactness,.the section being taken on the line 4-4of Fig. 2 lookingin the direction of the arrows; I

Fig. -5. is. a fragmentarydetail sectional. view taken. upon the line 5-5 of Fig. 4, looking in. the direction of the-arrows; p

Fig. 6 is a fragmentary sectional view taken upon the line 66 of Fig.4, looking inthedirection of the arrows;v and Fig. '7 isa fragmentary view in. sectional elevation, the section being taken upon .thelineel- -l of Fig. 4, looking. in the direction of .thearrows.

The illustrative abin. comprisesza. circular basemember I which carries anaupstanding-.-sha-ft.2 upon which bin. sections 3 are: mounted w-ithlca- Pacityfor-rotation!relativexto the haft andxto one another.

, The base memberl is desirably a m'oldedbase formed of concrete. Theconcrete base is poured in a mold andis caused to set with'the lower endof a tube, which forms part .of' the shaft 2, eme bedded init in, position to cause the tubeto-extend vertically upward from the-center of the base.

The shaft 2 c0mprisesthemetallic' tube re-''. ferred .to. and. a filling of .concrete, .whichtfilling embodies the princiiratelement for imparting strength .and rigidity. to, theshaft. The tube is notv the usual, thick-walled tube which has served by itself asthe central shaftof prior revolving bins. It is a much lighter gauge tubing, chosen of suitable thickness to serve primarilyas a mold for the contained concrete, and as a metallic bearingfaceforthe concrete in service. .The described; construction greatlyrreduces the. quantity of metal required foriuse in. the -.base and in the shaft, this being a particularly, important advan: tage at the'present time.v The concrete of the base maybe of different composition from the concrete of the shaft, but united integrally withit; p

Each bin section 3 is revolubly'mountedon the shaft 2 by means of a central sleeve 4. A'su'pport.

ing pin 5" is passed through holes in the shaft 2 to extend'diametrically through 1 the shaft and protrude at opposite sides thereof. A hearing washer 6 is supported upon'the shaft and. supports, in turn, a ball bearing 1. An; annular, a'n gular bearing member 8 is affixed within the sleeve inearthe lower endof the sleeve, in any suitable manner, for example, by welding it to the sleeve. The member 'fl'rests upon the bearing 11 and carries the weight of the bin section. The

- divideryso that the floor member, which 'is re quired. to carry considerableweight, was sup ported from the central sleeve "4wthi'ough theioermanent dividers. This-construction is not available where the dividers and the floor members are of non-metallic material.

Means are accordingly provided for directly supporting the floor member II in part from the central sleeve 4. To this end a flanged sleeve I3 is fitted within the lower portion of the sleeve 4 and affixed to it as by welding. The sleeve I3 is formed with an-outwardly extending flange I4, and the sleeve 4 is formed with an outwardly extending flange I 5. Prior to the securement of the sleeves 4 and I3 to one another, the floor member II is impaled upon the sleeve I3, and clamped between the flanges I4 and I5. The inner margin of the floor member II is thus securely and permanently clamped and strongly supported by the sleeves 4 and I3.

Additional support is provided for the floor member II through the permanent dividers I2 by means of light gauge sheet metal connecting brackets I B, I I and I8, which may desirably be duplicates, or substantial dupplicates, of one another. The structure is most clearly illustrated in connection with the bracket I8, and will, therefore, be described in connection with that bracket. The bracket I8 is a piece of sheet metal folded to provide parallel walls I9 and which are placed in embracing relation to the outerlower corner portion of the divider I2.

Each wall I9, 20 is formed with an outturned flange 2| having an opening 22 through it. The flanges 2| are secured to the floor member II by suitable fasteners such as rivets 23. The

.bracket I8 is also permanently secured to the per- The bracket I'I extends around the upper edge I of the permanent divider at the inner end thereof and is secured to the permanent divider I2 by rivets 24. The'fianges 2| of the bracket I! bear against the sleeve 4 and are permanently attached to it as by welding.

The bracket I6 extends around the lower-edge of the divider I2 at the inner end thereof and is permanently attached to the divider by rivets 25. The flanges 2| of the bracket I6 bear against the sleeve 4 and are permanently secured to the sleeve as by welding.

It will be seen that the principal elements of the bin unit have .been replaced by non-metallic members, and that a strong, rigid and permanent structure has been provided through the employment of a single short sleeve I3, for each bin section, and the three corner brackets I6, I1 and I8 in connection with each permanent divider.

The outer wall of the bin, which was formerly made of metallic wall sectors, is in the present construction replaced by non-metallic ,wall'sectors 26. Each of these wall sectors 26 carries at its opposite sides an angle bracket 21 which is secured to the wall member by rivets 28 and which includes an inwardly extending web 29 adapted to extend alongside the bracket I8 and to be removably attached to it. A headed bolt 30 is passed through adjacent webs 29 of adjacent brackets 21, and through the wall members I9 and 20 of the bracket I8 as well as the interposed divider I2, and the parts are'clamped together by a nut 3| threaded onto the [bolt 30. The

. bracket I8 may additionally be secured to the permanent divider I2 by a rivet 32.

While the attaching means'just described for the wall members 25 may be practically employed, I prefer to use the connecting means described and claimed in my pending application Serial No. 461,848, filed concurrently herewith, now Patent No. 2,311,130, and illustrated in Figs. 4 and 6. In this construction the bolt 39 and the nut 3| are replaced by a rivet 33 which passes through washers 34, spacer sleeves 35, bracket I8 and divider I2, and holds the parts referred to rigidly together in fixed relation to one another. Each web 29 is formed with a horizontally extending slot 36 for receiving one of the spacer sleeves 35. A latch 31, pivotally mounted on the web 29 by means of a rivet 38, is adapted to be swung down between the web 29 on which it is carried and the adjacent washer 34 to assure that the web 29 will bear continuously and firmly against the adjacent wall of the bracket I8 when the parts are in assembled position. The bracket I8, unlike the brackets I6 and I1, is formed with outwardly extending bosses 39, and each boss is adapted to fit into an opening 40 of the adjacent web 29. The parts are thus firmly and rigidly, but separably secured to one another.

The bin is also provided with removable dividers 4| by means of which the compartments defined by the permanent dividers lz maybe subdivided at the Will of the user. The removable dividers 4| are formed of non-metallic material with the exception of small pieces of joining hardware. Each removable divider 4| has secured to the inner end thereoflby means of rivets 42, an offset plate 43. I

The tail portion'44 of each plate 43 extends beyond the inner end of the divider 4| and forms a tongue suitable to be inserted in any one of a series of slots 45 which are formed in the sleeve 4 between the upper extremities of the brackets I6 and the lower extremities of the brackets II. Each removable divider 4| also includes a pair of opposed angle plates 46 near the outer end thereof which are secured to the divider 4| and to one another by suitable through-fastening means such as rivets. Each angle plate 46 includes a horizontal flange 4'! which is adapted to bear against the floor member II, and which has an opening formed through it. Holes 48 are provided in the floor member I I, being circularly arranged, so that a removable divider 4| may have its tongue 44 thrust through any one of the slots 45, and may be attached to the floor member in radial alignment with the slot which is used, by means of bolts passed downward through the horizontal flanges of the angle plates 46 and through the appropriate holes 48 of the floor member. 7

It will be evident, of course, that the described construction makespossible a very substantial reduction in the quantity of metal employed, and that it provides a strong and rigid bin section capable of performing heavyservice.
