' The present invention relates to improvements in non-clogging bin structures.

More particularly the present invention relates to improvements in bin structures such as, are used for supplying materials to scale cars such as used in connection with blast furnaces or anal ogous structures. The bins are ordinarily elongated parallel to the direction of movement of the scale cars and are provided with a plurality of gates spaced along the width of the bin struc tiir'e for controlling the delivery of 'material to the cars. It is desirable that each bin gate be of only moderate length for convenience in discharging measured quantities of material and also for convenience in operation and control. The full width of the bin is divided into perhaps four gates, more or less. Difficulties have arisen in bin structures in common use due to the fact that the sloping iioors of the bins have been provided with hinge structures for the gates, forming relatively wide obstructions, rather closely spaced from one another, permitting the arching of material between the obstructions; This arching adds to the difficulty of discharging the materials, requires manual labor, and is unde-' sirable. "An object of the present invention is to provide a gate-controlled bin structure presenting a minimum of obstruction to the flow of material there from. .A further object is to provide a bin structure having a swinging gate, the fulcrum means for i said gate being located out of the path of ma-'- teriai in the bin structure.

Figure 5 is a sectional view taken on the same the bin gates;

Figure 6 is a sectional view somewhat similar to Figure '2 but illustrating a modified construction.

Figure 8 is a view in elevation taken in the: direction of the arrows 8-8 of Figure 6, the liftj ing member on the scale car being located, however, at a level Where it strikes a yielda'ble proture.

Referring first to Figures 1 to 5, the numerals l0" and II indicate the sloping walls of a bin i leading to a throat indicated by the numeral i2.

The outer boundary of this throat, adjacent to the .wall I0, is defined by the rail I3, which is shown in inverted position. Spaced downwardly and outwardly from the rail i3 is the rail l4. Both'of said rails are fast with respect to the walls in and II. ..The space between the rails; l3' and i4 permits access to the interior of the bin from the outside thereof. The angular relationship between the locations of the rail [3 and therail l4 will be such that there will be no tendency for material within the bin to escape 3 therethrough. However, the space between the rails I3 and I4 may be closed, if preferred, by a closure means, preferably removable.

Disposed along the width of the bin, that istransversely of the bin structure as illustrated in Figure 1, are a plurality of housing members or fulcrum protecting members l5-l5 having the side walls [6-16 and the top walls IT. Thetop walls Illl of the housing members are securely fastened to the bottom portion of the;

rail M.

The housing members I5-I 5 provide receptacles for the swinging arms of the bin gates, and,

also accommodate fulcrum means. forsaid swing-.

controlled by a double gate mechanismincludi ng the inner swinging gate l9 andthe outer swinginggate 20. These two gates l9 and have a common aXis of swing, indicated by the numeral 2|. Preferably the axes of swing of all of the pairs of gates l9 and 20 cooperating with the same sloping wall II will be disposed in line.

The two gates I9 and 20 associated with each opening I8 cooperate with each otherto perform the well known function of double gate structures, of insuring the stoppageof flow of material even though one Of the gates should be closed upon a lump of material and should therefore be held partially open, as explained in the patentjto Hayes No. 1,525,236.

The inner gate I9, whichis of arcuate crosssection having its axis coincident with the axis 21, includes two swingingarms 2 2'22. the. outer gates 20 includes two swinging arms 23-23. A swinging arm 22 of one inner gate. [9 and a swinging arm 22 of the next adjacent inner gate [9 are located to swing within the'same home ing. member l5. A swinging arm23 of one outer gate 20 and a swinging arm 23 of the next adjae cent outer gate 20arealso located within the same housing member l5. This is clearlyillustrated in Figures 1, 4 and 5. The adjacent swinging arms 22-2.2 of adjacent inner gates I 5 and'the adjacent swinging arms 23-23 of adjacent outer gates 20 are swingingly mounted upon a 'cylindrical member 24, bushings22a and 23a. being provided to reduce friction. Each member 24 is;

carried by a pair of-lugs 25-25 fast to the supporting structure of the adjacent sloping wall II. A keeper 26 is provided for securing thecylindrical member 24 against either longitudinal or rotative movement relative to the lugs 25-25,

Each inner gate I9 is provided, adjacent to each of its side extremities, with a reinforcing angle 26 and a lug 21. The lugs 2'!,21 at the two extremities of each inner gate I9-are adapted to be engaged on their under sides by the swing-j.

ing arms 23 of the corresponding outer gate 20;, Said lugs 2l2T, as shown in Figure 2, are dis:

posed at a materially higher level thantheplane, bounding the upper extremities of the swinging arms '2323 of the corresponding outer gate 20, so. that when an outer gate20 is raised the lifting of the corresponding inner gate [9 will occur after Each. of

the outer gate 20 has risen through a material distance. When the outer gate 20 is lowered, the inner gate 19 will close before the outer gate 20 closes.

The swinging arms 2323 of the gate 20 preferably take the form of channels. The closure portion of the gate 20 is .made up of the channel 28v and the angle 29. Mounted upon the inner side of the channel 28 is the bracket 30, which includes the two arms 3l-3l spaced apart and supporting the roller 32.

Thenumeral'33 indicates an arm which may be.. carried by-a scale .car or other receptacle for receivmg. material from the bin. The arm 33 may be raised or lowered by mechanism not illustrated. Such mechanism is well known to those s'killedin' the art'and need not be described in .detail.

ing arms 23-23 thereofgwill engage the lugs 2T-2'l' of the inner gate tflywhereby furtherliiting movement of the arm 33 will result in the raising of both gates. The gate'f9, as'shown in dotted lines inFigure 2, maybe raised up to a region where the upper edge of said gate l9 is in.

proximity to the rail [3. Material from the bin will fiowdown through the openings l8-l8 be-' tween the housin members l5. The top walls; l|..l1 of the housingmembers |5l5 will not',

be. effective to retain any considerable amountol' material flowing down from the sloping wall H,'

and will not provide effective abutments for arching of material thereac'ross; In the event, however, that any such arching should occur, it would be a simple matter for a wqrkm'amatter thegates have been lowered, 'to insert a tool through the space between the rails l3 and H to break such an arch.

The fulcrum'means for each of the gates l9.

and 20 .is located out of the flow of .material in the bin, so'that said fulcrum'means will "not become clogged with such material, andgof "course, present no obstructions for theundesirable arching'of such material. The. gate means move in, an arc disposed entirely above said slopingbota tom wall but said gate means are fulcrumed upon means disposed belowthe sloping'bottom wall;

The arrangement'is su'c'h'tha't there is no interruption in the floor of the bin or passage, since the fulcrum is disposed at the two' sides 'of each gate i in an intermediate region between adjacent gates.

According tothe construction illustrated-in Figures 6, 7 and 8.,Ithe' bracket on theonter gate is 'yieldable longitudinally of the bin structure, that is-a1o'ng theline of. movement of the scale car.

Referring to Figures 6, '7 and 8, a scale car is in-- dicated by thenumeral 350,, which scale car is provided with the lifting arm 38. Saidjarm takes the form of a bracket carryinga short roller iif, theirollertl' being adapted to engage the under side of the bracket Edwhena lifting force is; to be exerted'upon' the' outer'gate 26a. Said bracket (H After the outer gate 20 has,

has a portio'ri'38 adapted to have a sliding movement against the rear side of the channel 28. Said channel 28 is provided with the arcuate slot 39 for receiving a pair of outstanding studs40-4IJ carried by the portion 38 of the-bracket 34. A pair of nuts 4 l--4| are carried by the studs 40'4fl and are adapted to frictionally hold the bracket 34 in right-angular relationship with the adjacent portion of the outer gate 20, as illustrated in Figures 6, 7 and 8. r p

The structure illustrated in Figures 6, 7 and 8 has the advantage that if the bracket 34 should be in position to be struck by the bracket 36 carried by the scale car when said scale car is moved, no destructive effects would result, the bracket 34 merely yielding in a swinging movement about the pivot line 35 to allow the passage of the bracket 36. The bracket 34 may then be moved back to its proper right-angular position with respect to the channel 28, the nuts 41- being turned down to yieldably hold the bracket 34 in this position.

The construction illustrated in Figures 6, 7 and 8 has the further advantage that the lifting force will, in practice, be applied to the outer gate 20a always in the same position symmetrically disposed with respect to said gate for the reason that the bracket 34 will be located symmetrically with respect to said gate. This will occur without careful spotting of the scale car carrying the bracket 36. It is more important, generally, to have this lifting force symmetrically disposed with respect to the outer gate 20a than to have the region of contact symmetrically placed with respect to the roller 31.
