' or DOUGLAS, ARIZONA concur1min non nor cont/lineman MATERIAL Application filed November Heretofore, attempts to provide bins or containers which prevent loss of heat from hot materialtherein have resulted in very expensive'installations, as linings of heat insulating materials are costly and maintenance of the same .is often troublesome. For ex- -a1nple,"when brick linings are used for bins for hot calcined ore the ore often sticks to the brick lining and when dislodged by hammering the bin sides or poking through holes in the roof the lining is often damaged. "If heat resisting alloys are used on the inner shell to protect the liningof heat insulating material the cost is even greater.

.0. 1 By the presentinvention b1ns or contalners are made'havingrelatively thin and'inexpensive metal Walls and provision is made so "that some of the particles of the hot solid material'that'are introduced into the bin are caused to form a stationary lining-alongthe inside walls. The stationary lining composed of the particles of material which are introduced prevent escape of heat from the W other portion of the material, as'this lining "forms a heat insulating layer adjacent the inner walls of the container.

The invention will be understood from the description in connection with 'the accom- A panying drawings in which Fig. 1 is a longitudinal section through an illustrative em- "Inthe drawingsreference character 1 indi I s1nelters,'but the invention is not restricted to this particular use.

cates 'a bin or recepta-cle that-may "be provided with an arch-shaped top or cover 2 that may bem'ade of refractory materialwhich is a good' heat insulator. The side walls 3 of the binareindicated as sloping inwardlyand :the'bin-is provided with a curved bottom 4 and also vertical ends5. I

"Queer-more openings 6omay be provided through the cover 2 for introduction of'hot material and one or more similar openings may oe-provided in the bottom for withdrawing 'thehot material.

Lbeams 7 are installed along opposite sides ofthe bin or container for supporting the same. Channel bars 8- may be-connected' along the outsides of the I beamjs 7 for strengthening purposes. Angle bars 9 are connected along the insides of the beams 7 for supporting the roof or cover'.2,1the edges of which bear against inside surfaces ofthe webs of "the "I beams 7. Rivets 1 0 passing through the webs of the I-beam's 'fl flanges of the channels 8, flanges of the angle bars 9,

and the upper edges of the side walls 3 hold these memberssecu'rely together. r

' Channel bars 11 extend across the ends of the bin on'the outside and angle bars-12 are connected to the channels 11 along *the inner sides thereof by means of rivets 13 Y which pass through the channel 'bars 11, flanges of the angle bars =12, and the 'upper edges offthe end Walls "5. of the bin. These members are thus "kept securely este megether. Walls 14 of"refractorybl'ocks such as'briok or tile,-are supported'on the jang le' bars "12 at the ends of the -roof'o1"cov'er' 2 to close the spaces. 7

A series 'of spaced-shelves-I5 which may be in the form oftroughsinade up Of plates with "sides at right angles to each other are-i-nstalled along the inside of the-ends 5 ofthe bin with the plates at 45 to thehorizontal. Metal straps 16 are provided for keepingthe shelves lojin-placeznear the walls 5'i'n position to catch and retainparticles of material that I are introduced into-the bin. The outer ends of the straps 16 a're'bentdownwardly and connected tothe shelves as indiea'ted at 1-7. Theintermed-iate portions of the straps 16 are connected to the shelves 15, as shown at 18, and the upper ends of the straps 16' are bent downwardly as indicated at 19, and lie in spaces between the inner surfaces of the.

portions of the straps 23 are connected to the shelves 22, as indicated at 25v and the upper ends of the straps 23 are bent downwardly, as indicatedat 26 and extend intospac'esbetween the inner sides of the walls 3 and bent-- out portions of the cleats 27 which are riveted to the walls 3, as indicated at 28.

In the modification shown in Figsa3and 4: the shelves 15 are kept in place by being suspended from above with spaces between them, instead of being held in place by means of straps riveted to the walls 5. In this modification bolts 30 having heads 31 at the bottom extend through holes provided therefor in the angle bars 12 and are kept in place and adjusted in position by means of nuts 32 on thebolts 30.- Spacers 33 which arethreaded upon the bolts 30 keep the shelves 15 spaced the desired distances apart. The spacers 33 are provided with'heads 34 at their upper ends having V-shaped grooves therein to fit the outside of the shelves15 and also with v shaped heads 35 at their lower ends to fit.

the inside of these shelves 15. The spacer below the lowest shelf 15 and the spacer above the highest shelf 15 are similar to corresponding parts ofthe other spacers. U-bolts 36 pass around spacers 33 near the lower ends of the bolts 30and are kept in place in the walls 5 by means of nuts 37 to preventthe suspended members from swinging.

In the modification shown in Fig. 511the shelves 22 are kept in place by means of bolts 30 instead of; straps. Spacedbolts 38 may extendfrom the upper flange of theI-beam ,7 through the angle bars 9 to help support these angle bars, the bolts 38 being adjusted in position for this purpose by means'of the nuts 39. Lugs 40 rest upon the angle bars 9.

Holes are provided through the lugs 10. and angle bars 9 through which the bolts 30 pass,

and are adjusted in position, for sustaining the troughs 22 by means of'the nuts 32.

When the bin is used for retaining calcined ore preparatory to introducing it into a re verberatory furnace the hot calcined particles are introduced at the top andare withdrawn fromthe'bottominto-thereverberatoryfurnace without appreciable loss ofheat In View of the. fact that the temperature must be very high in the reverberatory furnace for smelting the ore, whatever heat is retained in the calcined ore as it is introduced is thereby saved, thus effecting a decided economy in the process. The particles which are caught by theshelves form a heat insulating lining for the bin whether calcined ore or other material is stored in the bin, so that the material can be kept in the bin for a consider- I able length of time and then removed while still retaining its heat. r

The above described embodiments of the invention are the preferred ones for retaining a layer of particles of segregated material on the walls of a bin to act as a heat insulator for the retentioncf the heat of the hot material,

stored in the bin. It is obvious that when a layer of the material is retained against the walls, the material so retained in that layer will gradually cool down; therefore any structuredesigned to achieve this end, must be free to expand and contract without causing deformation of the main bin-structure.

Were "it not for the temperature stresses v due to unequal expansion, it would be pos sible to effect the purpose of the invention-by building the bin withtwo shells, an inner shell and an outer shell, the distance between them being equal to the thickness of the material neededto furnish therequired heat insulation, and filling the space between the inner and outer shells with particles of the segregated material. While this would be the simplest possible construction, the result would be that the inner shell would attain V V a temperature only slightly less thanthatof the material stored in the bin while the temperature ofthe outer shell would be only 7 somewhat higher than the atmospheric tem-' perature. The inner shell wouldtherefore expand muchmore than the outer shell. If the double shelled bin were built so as to permit or provide for this unequal expansion, fine material could not be stored in it i 7 without excessive leakage occurring; on' the other hand if the double walled bin were built so as to be tight to fine material, the unequal expansion of the two shells-would cause excessive deformation of the binand ultimate failure. j I It is to be understood that my invention is not limited to the embodiment shown herewith, they being. merely the preferred m eans of embodying the invention but that any structure that comes within the" scope o'fthe claims andretains a layer of the material (against the walls without'atthe same time introducing undue temperature stresses, in

the structure is within this invention.
