i IMPROVEMENT IN ORE-ROASIINGI'URNAGES.
TO ALL WHOM 14T M AY SCNCERN: i
- Be it known that we, DAVID C. COLLIER, SAMUEL CUsnMAN, and NnwnLL E. FAnnELL, of Central City, in
the county of Gilpin, Colorado Territory, have in'venteda new and useful Improv'ernentl in Ore-Furnaces; and
we do hereby declare that' the following is aiull, clear, and exact ,description `thereof, which will enable oth-ers skilled in the art to make and use thc same, vreference being had to theaccompanying drawings, forming 'part ofthis specification. i V
' This invention relates to a new andV improved method of constructing furnaces for the wasting and ehloridining of ores, wherebythe same is moreeii'ectually and economically done. i
In the aecompanyingplates of drawings;- l Figure l isla sideview of onr'invention. `Figure represents a central longitudinalsection of the same, taken inthe 4line-:1: zc, fig. 1. VFigure 3 ifs u detail view-ofv the partition-tiles, showing 'the manner offjointing and supporting the same in the centre. l y' 'Y Y Figure 4 is a detail view of the same, showing also the tiles by which the supporting-rods are protected against the fire. y i i Figure 5 in an'end view ofour invention. t Similar letters of reference indicate corresponding parte. llh'e'cylinder A is made of boiler-iron, of the thickness of about three-sinteeuths of an inch, and'may be -of any convenient length, according tothe quantity of ore to he treated; but we have found the length of, ten
feet, orthereabouts, to answer all the requirement, the diameter of the sanneV being 'aboutve feet, and is provided withsuitable heads P, to which are rigidly attached the tubes F and G.
The cylinder Af 'is' lined .upon the inside with irebricks or tiles, or other suitablehmaterial, so as to fbrm a re'fproof lining, d. Said lining'a may be of any convenient thicknesaas of the thickness of about three inches. Said cylinder A is providethnear one endiof the same; on thesidelv further from the tube G, with a. man-hole, H, and`near the other end of the same, on the oppositel side, or the side further from the tube F, with a manhole, I, by means of which the charge to the cylinder A ispbothA admitted and discharged. Said man-holes H and I are provided .with suitable covers, the joints around the saine being'luted for' closing said man-holes.
Extending across the cylinder A, from one side to the other, is a partial partition, iormed of iron orl other' suitable material, or of the tiles D, as showninthe drawing. v l
Thertiles D', commencing at about sixteen inches from one end of the cylinder Agfare lapped one upon the other, extend tonithin sixteeninches ofthe other end of said cylinder A, as sbowii in the drawing, fig. 2, and so that said tiles Dfo'rma partition in a-plane, passing through and coincident with. the rotating axis of the cylinder A, and so as to be at right angles to aline drawn from either'of the man-holes H and I to said partition. The tiles D` may he made of clay, or other fire-proof substance, in two parts, masoned by one lend into the lining a of the cylinder `Aganclvlapped together inthe centre of the-same, one end of-each part of said tiles D being bevelled off for that purpose, or thesame'may bearranged in any other way, so as-to form a' partition f through the grated part of the cylinderA, as shown in the drawing. The tiles.D are supported by the ironbolts a', passing through' said tiles D, in the centre of the same, and the outside ol" the cylinder'A; said bolts4 tilesl'D. Y v
The tiles E are made of any of the ordinarylre-proof materials for that purpose, 'are square linform, or may be of any convenient foi-m, providedwith a'holethrough the same longitudinally to receive the bolts a a being protected against the heat by acasing'offre-proof tile, Efwhich saidcasing E also supports the nnd r naybefor'med, 'of one piece, or of any convenient number of pieces, in'which latter ase-they arelcss liable Ito be cracked or broken by the unequal ekpans'ion'of the parts.
-The bolts a aro'provided on each` end with nuts, by means of which the tiles D are firmly held dO'Wn upon large as to resist the inuenec 4of the same.
The object of the partition above described is to receive and hold the oro deposited or falling 'upon the same at each semi-rotation of the cylinder A, so as to receive the full actionof the heat upon tho same, the ila-me being divided by said partition, and thereby coming more immediately incontact with the particles of ore hold-for atime upon said partition, .the ore, at every rotation of the cylinder A, by the 4alternate elevation the tiles E7; the nuts on the inside oftheoylinder A 'being either protected against'iircby claypor made lso and depression' of each end of the same, hereinafter'more fully described, being shil'tednearer tothe end of the cylinder.` v
Intocaoh end of thev cylinder are rmly bolted cast-iron heads P, in the ordinary way. The heads P `are formed of arms or spokes, so as to receive fire-brick or other re-proof substances to vcomplete the cylinder Al To the 'heads P, either a part of titel-same, or rigidly secured thereto, are short metallic ilatted or oval tubes F and G. Said tubes F and Gr are made of cast iron, and are each provided, upon onesidc of vthe same,
with a iiange, which, with the tubo itself; forms a circular plate or ring, whose centre is the centre of rotation ofthe cylinder A, and which isso far removed from the centre longitudinal line of thc cylinder A as to give to each end of the cylinder A an alternate elevation and depression, at each revolution of the same, equal to ltwice the distanceI from the said centre of rotation to the said centre line of the cylinder,vwhich willbe abd'ut fifteen inches or one-fourth vof the diameter of the cylinder A; the object of said tubes being to afford a con venient means of opening a communication with the tire in the fire-box J by the tube F, and with the iiue K by the tube Gr, While rotating within the masonry of the same, and so as to4 pgevent the escape of heat from the furnace J except through the cylinder. i v -v The said tubes E and G may be of any diameter sucient lto allow the heat to pass from the dre-box J through vthe same, as ofthe longer diameter .inside of about three feet, and of the shorter diameter of about two feet. v l I l v Said tubes -F and Gare lined in like manner as the cylinder'A with the lining a.
The cylinder A is supported by and rotates upon two'wheels B, around the same, asshown. Said wheels B arc made' of cast iron, and are provided, around the openings to receive the cylinder A, with spokeso'r arms,'
which are a part of the same, whereby the same are made lighter and cheaper. The openings to receive the cylinder A,a.rc a little `larger than the cylinder A, so as that the wheels B may not be injured by the expansion of said cylinder A, and said openings are at one side-oi` the centre 'ofsaidwhe'els B.
Said wheels B are secured to the cylinder A by feet or chippings around the openings in the same, through which pass bolts;` said bolts also passing through the cylinder A, and are provided withsuitable nuts, by means of which said wheels B are firmly secured to said cylinder A. l
Thewheels B may be of any convenientdiameter, as of the diameter oi' six'an'd ahalf feet, and are placed at an average distance of` one-quarter of the-length of said cylinder A from each end of the same,vand so that the cylinder A is nearest to the circumference of one of the wheels B, at one endpfoflsaid cylinder A, and nearest the circumference of the other of said wheelsatthe other endof said cylinder A; thecentre of both said wheels IBI being'in the line of' `the rotation of said cylinder A, each end ofthe same will bealternately elevated 'and Adepressed by the rotating of the wheels B upon the friction-:dllei-s'Ii.
The wheels B are placed upon the cylindei` A, at right angles to `the centre of the rotating axis of the'sume, andare provided with a suitable rim to rest upon the friction-rbllers L, and must be of suflicient thickness to give the requisite' strength. y v Upon any suitable foundation, and rotating in suitable bearings,- on any blocks, so situated as to hold the cylinder A in proper position with respect to the furnace J, are the friction-.wheels or rollers IL, to receive the rims 'of the Wheels B, as shown. t ,f K
Upon the face of the tvhecl B, nearer to the {ire-box J, or u"p`on either of said wheels which may be more convenient, and upon a suitable flange for that purpose, is the spur-gearing C. v l
Upon any suitable support, N, and rotating in proper bearings thereon, is-the/driving-'shal't O, and upon said shaft O, at any convenient p'oint, is keyed a pinion, M, so as to it into the ge'aringvC, by means f which the cylinder A it maan.
The gearing C upon the wheel B, and the pinion M, are to eachother, with'respect to their several diam-v ete'rs, and the number of teeth in each, in such ratio as to give the required speed to the cylinder' A, which -rnust be very slow, or about one revolution each minute.
lWit-hin the cylinders A, upon each of the heads ofthe same, are the shelves e, made of hre-brick, projecting inwards, so as to prevent the ore from falling out into the tubes F and G when the cylinder is rotating or being charged.
Tho fire-box J and flue K are constructed inA the ordinary way of constructing 4ilues and fire-boxes for treating ores; Aa suitable chamber b-eing provided in the ilue K to receive any ore which, by the rotation of the 4cylinder A, might fall into the said iiue- K. l
The operation is such that, by placing the ore to be treated in Athe cylinder A, through the man-holes in,
' each end Aof the same, a suitable iire burning in the fire-box J, tho-cylinder A is made to slowly rotate, when,
by the alternate elevation and depression of each end of the cylinderA, the ore is carried from 'end to end of the cylinder, falling upon and retained a short time at\cach semirotation of the cylinder A, passes entirely around the partit-ion in the same, and is thus subjected in every particle to the great heat from th'e iiretbiox J,
' whereby the sulphur and other impurities` are driven from the ore,
Having thus described our invention, what We claim as new, anddesire to secure by Letters Patent, is- 1. An apparatus for roasting and chloridizing ores, composed 'of av cylinder, A, rotating on an axis inclined to the true axis ofthe cylinder, Within which, inthe line ofthe rotating axis, is a partial partition for receiving moza' 8 and retaining the oro for a short time' at cach semi-rotation of the snid'oyinder A, in eombinntion with a. tirebox, J, and ilus K, 'substantially as sho-wn `and described, and for the purposes set forth.
2. The wheols B, in combination with a, rotating cylinder, A, subtnntiolly as shown und d-e|crb-ed,'ond
for the purposes set forth.`
3. Tho'p'artial partition, in o plane in. the centre of the' rotation of tho cylind-er A, :md` plialeed 'at right anglo to a. line, drum from ltho man-hole H or I to said partition, or its equivalent, and in combination therewith, und with anyre-box, J, onbsthntially as shown unil described, and, for the purposa set forth. 4 El.lua above speoication of our invention aign'od by un, this day f y, 1867,
