IMPROVEMENT IN PUDDLlNG-FURNAC ES.
Specification forming part of Letters Patent N 0. 169,047, dated October 19, 1875; application filed April 17, 1875.
Britain and Ireland, manufacturing chemist,
have invented an Improved Furnace for treating iron and other substances, of which the following is a specification:
My invention relates to that class of furnaces in which the metal is subjected to treatment on an annular rotating bed; and the object of my invention is to facilitate and render automatic the discharge of the metal after treatment, a further object being to render the rotating bed less liable to injury from the excessive heat. These objects I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of my improved furnace. Fig. 2 is a plan. Fig. 3 is avertical section to an enlarged scale in the line A B of Fig. 2. Fig. 4 is a similar section in the line 0 D of Fig. 2. Fig. 5 is a section in the line E F of Fig. 3. Fig. 6 is a section in the line G H of Fig. 4.. Fig. 7 is a cross-section through one of the standards for supporting the stirring apparatus. Fig. 8 is a side elevation of part of one of the standards, with raising and lowering gear of stirring apparatus.
a a is the annular bed or receptacle, which is shown as being made of iron, at lined with fire-brick or fettling a. It is arranged to rotate about its own axis, and travels on antifriction wheels I), carried by iron standards I).
c and c are two annular walls, supported by iron plates d 01, carried by iron pillars e e. The walls 0 c form an annular space or chamber, 0 which is covered by the brick roof supported by the side walls.
The annular bed or trough a may be made either of sheets of wrought-iron riveted together, or of cast-iron made in sections with suitable flanges, and bolted together.
It travels within the annular chamber 0 on anti-friction wheels I), on which rest the annular rails g, supporting the bottom of the annular bed. The bed is guided by wheels 0*",
carried by sliding journal-boxes arranged under the inner wall-plate and made adjustable;
by screws 0", as shown. it is a reverberatory fire-place, situated at the side of the annular chamber 0 so that by the use of the annular bed a a, in combination with the stationary wall 0 c and annular roof 0 an annular flue is formed, of which the rotating bed or receptacle a, a constitutes thebottom, the wallsc c the sides, and the roof 0 the top. The bed of this annular flue, so formed, contains the materials onto which the flame and intenselyheated products of combustion from the fireplace are reverberated or caused to impinge. The exits for the products of combustion, from the annular flue are at it". They lead into another flue, h, so that the flame and heated products of combustion on entering the annular flue are split up or divided into two streams traveling in opposite directions along the annular flue, as indicated by the arrows in Fig. 2, and meeting and leaving together by the exit h as .shown. 2' 41 are annular gutters or channels carried by the walls 0 c and containing pulverized ore or other granulated luting material or liquid sealing, into which dip the flanges or feathers 'i' t", carried by the rotating annular bed.
By this arrangement I prevent the escape of the heated products of combustion and the access of cold air between the sides of the rotating annular bed or trough a a. and the walls 0 c c is an openingformed in the, annular r00 0 for the insertion of instruments for mixing, turning over, and otherwise manipulating the substances under treatment.
The apparatus I employ for this purpose is constructed as follows: At each side of the rotating annular bed I fix two stationary standards, k, of the cross-section shown in Fig. 7. Between the flanges k of each standard works a rack, l, in gear with a pinion, m, carried by a cross-shaft, n, to which rotatorymotion may bev communicated, when required, by any well-known arrangement for the: purpose. The racks l carrya cross-frame composed of two bars, 1 l between whichwork, in gear with each other, anumber of spurwheels, 0, whose spindles 0 .have their bearingsin the bars Z P, as shown. One of these wheels gears with a spur-wheel, 0 formed rers shall be brought in to action before touchand lowered into position for operating upon with a short hollow spindle or elongated hollow boss, 0 Through this hollow spindle ,or boss passes the upper part of an actuating spindle or shaft, 0, driven by suitable gearing. The upper part of the spindle or shaft and the hole in the hollow spindle or boss 0 are of angular section, or feathered, or otherwise arranged, so that the hollow spindle or boss, and its spur-wheel, are left free to move up and down independently of the actuating I spindle or shaft 0 but cannot rotate without turning it when in position for work. 0 is a bevel-wheel fixed on the actuating spindle or shaft, in gear with a similar wheel, .o on a horizontal shaft, 0", driven in this case through miter-wheels 0 o by another shaft, 0", provided with fast and loose pulleys o 0 so as tobe driven by a strap or band. *This driivw ing arrangement may obviously be modified tosuit circumstances. The spur-wheel 0%,; driven by the actuatingspindle or shaft of, as l' abovedesoribed, communicates motion to the l, train of spur-wheels o in gear with it. The f gstipringimplements parecarried -by1the'1owerl endsof the spindles 0 of the wheelsoso as to dip into and agitate the materials contained; inthe annular bedof the furnacewhen the said-spindles are rotated by theirwhelso.
I place the stirring apparatus between the exit-openings h of the annular flue, as -shown, the temperature there being comparatively low, "in consequence of the heat being mainly j drawn away by the exits h and *I for-m the thereof-c with a-ldip or screen running. as it were, across the annular flue at =eachgside of the openings, so gas to protect "the "stirring apparatus from the :direct actionof the-products oficouibustion. The screens do not dip into the materials contained in {the rotating annular bed.
Portions of #the flanges k i of the standards near their upper parts are removed to enable the frame I l with the wheels 00-, spindles 0 and the agitators, when raised by the racks l, to be withdrawn and replacedfor a duplicate set of apparatus substituted.
Insteadof the hollow boss 0 1 may use a clutch-box, the segments of the box being made sufliciently deep to insure thatthe stiring the material required to *be stirred.
The standards are formed with projecting "partsor brackets la k ibrming tables or supportsyso that when one frame, I i, 'with its Wheels, spindles, and stirrers, "has been raised, it :may be idrawn out from the racks alon-gthe ione pair of tables or supports,'say, k, and an other similar setof apparatus kept in readimess on the :other pair of tables or supports, sayflc may be thereupon 1 slid along )the said tables or supports into gear with the racks Z,
thematerials under treatment in the annular bed. The apparatus withdrawn will be supportedby the tables or supports k and,ifnec essary, its stirring implements 10 may "be removed and others substituted. i
In this way two sets of apparatus maybe used alternately, in such manner as to cause,
practically speaking, no interruption in the stirring of the materials under treatment.
To enable the materials that have been treated in the rotatingannular bed to be readily removed, I construct thefurnace so as to ileavea space at one side between the upper edge of the annular side of the rotating .bed and the roof, as shown at 0 Fig. 3, for
whichpurpose, in the arrangement illustrated,
I provide a small archway, c", projecting in a radial direction from the annular roof c. This archway is provided with a sliding door, lGOll-StI'UCtGd of iron, 0", lined with fire-brick c and arranged to be raised and lowered or held in any required position by means of a lever, q, having its fulcrum at ganu; pro- -vided witha slidingweight, The inclined *bottom of the opening tconsists of an iron 31 ris a frame, having groovesor guidesr jijin which slide the respectiye eudsiof a deflector, s, constructed in the present instance: of iron. This deflector, as will be seen by the plan view, *Fig. -2, is arranged in ,a direction tangential or at an angle to the lateral rpart ior sideof the annular bed. Itismade adjustable vertically by means of 1a chainysfiand difl'erential pulleys 8 By this arrangement the deflector s-caube adjustedtoan y required height in 'the due ,0. "When the deflector is lowered it dips into and forms a partition across the bed of the ifurnace in sueh manner as that the materials req ired to be removfid {from the said bed being,-by the rotating action of the bed, broughtflagainst the saiddeflector, are thereby accumulated'and deflected or thrown aside andcaused topass over the side ;of the rotatingannular bed through thge opening (flout of the furnace into anysuita- *ble receiver. Whenthe annnlar bed "is tolerably full the deflector may,iin somewcasesybe advantageously lowered, so as to dip gat 'first "only slightly into the contents fthe bed,
thereby, as it were, skimming the same :at afirst, and after aportion of the contents mew beeuremoved from the bed the deflector may be gradu-allylowered until it finallyassumes its lowest position toward *the conclusionjof the emptyingoperation. i "When removing iron in apasty state I cause it to accumulate by meansof the defleetor, and I remove theaccumulated balls byfmeans of shovel, tongs, orotherwise. p
The water chamber'or vessel t consists of an annular tan'kyconstructed of wrought-iron This tank extendssome distance up the sides of the annular rotating "bed; The walls 00 forming the sides of the annular flue c, are caused to overlap the upper edges of the annular sides of the bed. The chamber 2? is provided with an inlet, t for cold water, and an outlet, t for water that has taken up heat from the annular bed. I place a wall or division across the chamber t, and arrange the inlet near one side of such division or wall, and the outlet at the other side of the division or wall. By this arrangement, as will be seen, the water is caused to circulate in contact with the outer sides of the lateral portions of the annular bed, as well as in contact with the outer side of the bottom of the annular rotating bed, and the bearings of the anti-friction wheels b are kept well lubricated.
Having described the nature of my said invention, and having explained the manner of carrying the same into practical effect, I claim as being novel and originaltaining water, and having an inlet and outlet for the same, with the rotating annular bed a a substantially as shown and described.
