Letters Patent No. 104,962, dated July '5, 1870.
HOT-AIR FURNACE.
The Schedule referred to in these Letters Patent and making part of the sam'c To all whom. it may concern: I
Be it known that I, BEXJAMINE S. KOLL, of the city of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Hot-air Furnace; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accom panying drawing, in two sheets, making a part of this specification, in which-- Figure 1 is a front elevation,'partly in section, illustrative of my improvement;
Figure2, by a like view, further illustrates it in a somewhat modified form;
Figure 3 is a plan view of the indicator;
Figure 4. is a perspective view of the beariug-rin g, on which operates the gratingshown in Figure 5;
Figure 6 is a sectional view oftig. 1, in the line a; x; and
Figures 7 and 8 are enlarged face and sectional views of the indicator.
Like letters of reference indicate like parts in each.
My invention relates to that class of furnaces known as warm-air furnaces, for heating dwelling-houses,
public halls, churches, and other structures, and the nature of it consists in an improved construction and arrangement of parts, whereby the ends in View are more perfectly and economically attained.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and mode of operation.
A cylindrical casing, A, or a series of such, one above another, constitutes the sides of the fire-chamher, into which the fuel B is fed through the coalchute B, which latter is closed by a door in the usual way. I
he casings A I prefer to make corrugated inside and outside, in order to increase its lieatflradiating power.
Surrounding this, is a chamber, C, for heating air, formed by an outer casing, 0', made and attached in any of the ways known to the art, and is provided with apertures c in any desired number, at or near its lower end, for the reception of cold air, and hot-air flues c at or near its upper end, for conducting the air which is heated by passing up the chamberO, thence into the apartments to be warmed.
Such furnaces have heretofore been put upon a foundation of brick, stone, or other like support, so as to make an ash-pit in such foundation, which had no connection with the furnace other than that of juxtaposition.
For the purpose of securing increased cleanliness, and a construction more convenient in putting up and changing location, I have combined with such a turn'ace a portable ash-pit, D, made of cast iron or other suitable material. This ash-pit D is closed in front by doors D, and from at or near its rear side an ash and dust-flue, d, leads to the chimney.
When the fire is to be raked out or cleaned, a damper of the ordinary construction, arranged in the flue d, is opcned aud the draught then through the doors .D will cause the dust and lighter ashes to be carried into the chimney instead of escaping at the open front :of the ash-pit, as heretofore, into the room or cellar .in which the furnace is put up.
Around thcnpper part of the inside of the ash-pit D, is a series of ledges, (Z, in any desired number, on which I- arrange a bearing-ring, F, of the form substantially as shown in fig. 4. This ring is made which, fitting into or engaging some fixed part of the furnace, shall prevent it from rotating. In its upper face I arrange, in any suitable way, a series of frictionrollcrs, f, preferably of chilled iron, on which I rest the outer rim 6 of the basket-grating E, which latter, (of the form shown'in fig. 5,) constitutes a part of thebot-tom of the fire-chamber. This grating is made with a radial series of grate-bars, c, converging downward from the outer rim 6 to an inner ring, c.
A skeleton frame-work e is attached to the inner ring 0, and the outer extremity of the main arm is turned up to form a book, 0 at or near the center of the ring c and such skeleton e is arranged at such a level that the inner grating E, when hung on the hook e by its central socket or hole, as shown, and is brought to a horizontal position, its upper face shall be even, or nearly so, with the upper face of the ring 0. The object of this arrangement is to provide a convenient means of emptying the lire-chamber.
. The grating E is kept closed by a pivoted arm, f, operating in the end of a rigid arm, f, of the ring F.
The grating, when closed, rests on the arm f and, by swinging this arm back by means of a rod, f, the grating E is at liberty to be turned to the position shown in fig. 5. For convenience in turning it, it has a handle, 0 A similar handle, e forms the means of .giving to the 'whole bottom of the fire-chamber an intermittent rotary motion, therim c rolling on the rollers f.
In fig. 2, I have shown the cover A of the firechamher of a conical form, and corrugated. From its chimney. The air passing up through the chamber The chamber 0 extends to thefurnacc-top G, as in with projecting corners f, or other similar device,
upper part a horizontal smoke-flue; a, leads olI" to the I arrange in the chamber I), on that side, a diaphragm, s, having perforations s. The form of this diaphragm is shown in-fig. 6, and its arrangement in the chamber b, a short distance above the pipes a, is shown in fig. 1. Its cfi'ect is to check the draught up that side of the furnace, and compel a portion of the: smokegheated gases, &ic., to traverse the smoke-fines and chambers on the opposite side of the furnace, so as the more effectually to impart heat to the currents of air in the air-passages.
The intensity of the fire controlled by a sliding damper device, n, of any dejsired form. The spring n, operating against a pin, 1',
or other fixed part of the damper-slide, closes the damper and shuts off the draught.
A wire, on, extends from the pin 'i' to one arm of a pivoted bent lever, i, such as is'used in bell-hanging, aridanother wire, rod,'or chain, m extends up to any of therooms above. There it is connected with an indicator, such as is shown in figs. 3, 7, and 8. This indicator consists of a frame or base-plate, p, by which it is attached to. the wall. It has slots o made like the slots of a sliding damperyaud over these slots 0 is arranged a sliding plate 1), having like slots 0'. To this plate 1) the rod or chain m is attached.
A hand-wheel, .q, on the end of a threaded bolt, g", which latter plays through a threaded hole inthe end of the plate 11, furnishes themea-ns of raising and lowering the plate-p.- The length of'th'e rod or chain at is such that the draught-holes of the damper me the holes '0 0' of the plates 1) p, shalhiwhen the chain is merely taut, be opened or closed the samein each. Then, by raising thefplate 1) so as to open wholly or in part the slots 0 o, the draught-holes in the damper n will be opened ,toLtbe same extent, and by lowering the plate 1) both will be closed together. An examination of the indicator will then alwaysish'ow whether or not, and how much, the-furnace-damper n is open, and atford the means ctr-regulating the heat without going to the cellar or basement, where the furnace is usually put up. But for greater convenience in adjusting the length of the chain m, and in keeping it always to the proper adjustment, I attach to the plate 10 a ratchet-wheel, l, and pulley, l, passing the chain ym' around the pulley, as in .fig. 8. By the use of a key on the square pin it the slack of the chain is wound up, and a pawl of the usual construction keeps 1 But to prevent too strong a draught on 1 the side of the chamber 7), next to the smoke-flue b,
I side the chamber is" it there. Should the chain need to be slackcned, th operation is reversed.
Thesmokc-flu'e a, (fig. 2,) it will be observed, not only extends out horizontally from the cone-A, but its inner end enters the cone and extends to ornearly to its center. By this arrangement, the smoke and gases of combustion are caused to act more uniformly on all parts of the cone, and also escape less rapidly from'the cone, so that a more perfect combustion is secured, with a consequent increased evolution of heat.
What I claim as my invention, and desire to secure by Letters Patent, is-- l. A bearing-plate or ring F, arranged on ledges d, inside the casingof a hot-air furnace, with devices substantially as described for preventing its rotation, as a support for a vibrating grating.
2. In combination with the bearing-plate of last .claim, a. series of friction-rollers, f, arranged therein, substantially as described.
3. I The dumping-grate E, hung on a toggle or book, 0, in combination with the surrounding vibrating basket-gratin'g-E, arranged substantially as described.
4. The lever j, pivoted to an arm,- f, of the bearing-plate F, in combination'with the dumping-grate.
E, arranged and operative substantially as set forth. 5. A coneshaped top, A, for a furnace, arranged -with a smoke-flue leading horizontally from at or near its center, substantially as described with reference to fig. 2.
6. A series of horizontal air-tubes,'a 41., arranged around the base of the cone A, and leading into the warm-air chamber 1), when combined with an annular smoke-fluc, b, all placed directly over the fire-chamher A, and surrounded by the outer warm-air chain-- her 0, substantially as described. '7. A perforated plate or diaphragm, 3, arranged un derthe throat of the smoke-pipe b and in the annular 10; In connection with a warm-airfurnace, an indi cating device consisting of two plates p 1), having apertures 0 o, the one furnished with a screw-shaft, or its equivalent, and so arranged that the damper-openings shall be shown by the indicator-openings, snbstantially as described. In testimony whereof, I, the. said BENJAMIXE S. KOLL, have hereunto setmy hand. i
