TO ALL WHOM IT MAY CONCERN:` v

Be it known that we, FEDEItA-L- GJADAMS and JOSEPn PECKOVER, bothrofCincinnati, Hamilton county, Ohio, have invented certain new and useful Improvcments'in Smoke-Burning Stoves; and wevdo hereby declare that the following is a full, clear, and exact'description of the same, reference being had to the accompanying drawings, forming a part of this specification', in which- I Figure 1 is a. perspective View of a stove containing'our improvements.

Figure 2 is Ialongitudinal sectional view' of the same.

Figure 3 is a perspective view of the bottom section ofthe stove, showing some of the details, and

Figure 4. is'a perspective viewof the plate-and dampers, shown in section at-V, iig. 2.

The object of our improvements 'is to Aprovide various means for the introduction and application of oxygen` tothe smoke and gasesiof coal or wood-burning stoves, so as to securetheir' consumption.

We do not-claim to have. discovered the .principle of applying the oxygen of the atmospheric air`to-this purpose, as Athis is wellknown, but we do claim to have invented variousl devices to eifect the concentration of the smoke andgases, and the application of fresh air to them at thebest point, and in the best'manner to'seeure a thorough consumption. l

These improvements we describe as follows: We place the hollow pipe or chamber A in the middle of 'the fire-pot." The bottom of this pipe is open, and communicates with the space above-the ash-pan B, so that air can enter freely from without, through theash-pan, and pass up the pipe. Above-thetop is a cap:,'C,so placed as-to` deflect the air-and distribute it in an annular current at its circumference. For the purpose of concentrating the smoke and gases, weplace upon the ire-pot a plate, D, having an opening around the pipe This plate may be made of a. single piece, covering the entire {ire-pot, except the opening, or it may be made of two.A

pieces, D and D, so arranged, on either sideof the fire-pot, as to leave aslotted opening extending. entirely across the pot, or these pieces may he provided with sliding doors or lids, E E, so as vto close a portion ofthc space ou each side, as may be desired. The effect of -this cover is to concentrate the. smoke and gases, either in the form of a ring around the pipeA, or in aA narrow current from' side to side, Air may befurther supplied by the holes :c :c :c rv, and also by the tubes F F F, viig.. 2, at the sides of the-refchamber, which tubes are fed with air from a base-chamber, G Gr, extending around the ash-pan on three sides, and provided with openings A H E H, for the'admission of air. n The oxygen, enteringpthe holes H, `pa'sses into the base-chamber, whereit is Vmeasurably heated,'thence upwardthrough the tubes F, and is discharged just under the plate D, coming in contact with `the smoke and gases atA the edge of the plate. p z

Another mode of introducing air and of concentrating gasesis to provide the stove with a plate, I, provided with an inverted conical pot, This pot may be fitted with an adjustable plate or diaphragm, L, to reduce the orifice at the bottom, orthe plateL may be omitted. A sufficient distance above plate I, to produce a space equal to the height of door W, is another:` plate, M, provided with a pot, N, the lower end of which is closed by a diaphragm, O, leaving only the opening P. Air enters through the door W into the space' between plates I and M, passes down between the conical pots, and is brought in contact with the smoke, Ste., at the oriiice P, producing a very perfect combustion.

"U/Another device is the cylinder or pipe Q, introducing air from above. It is very similar in its construction to pipe A in the {ire-pot. Air is fed to pipe Q through the opening at the top, or ,by pipes or iiues R R, and,

by means of apipe, shown by dotted lines at S, 'air may belfed from pipe Q to the space between plates I and M. This flue S extends obliquelydownwad and backward from the pipe Q, and enters the plate'M'just beyondthe edge' offthe pot N. 'To facilitate the combustion of gases, by means of air introduced through pipe Q, a

.concentrating-plate or diaphragm,.T, is placed in thexplane of the lower edge of pipe Q." Aange, U U, extends around the bottom of said pipe, and a cap isplacedjust below theope'ning, so that the 'air'.escapes around the angc U U and comes in contact -with the-gas and smoke in the space between the liange and the diaphragm T. For the purpose of retarding theA draught'or of forming a heating-chamber, the plate V is placed a little way below the top of thestove, and may be provided with the regulating-dempers Z1 Z2, at the front and back,

to open or c losc a spacefor the ascent of the products of combustion, thusvpermitting them to vseek the exit#l pipe directly, or compelling them'to passl over the plato V. The damper in the rear may b'e dispensed with, and' 2 'fasse the plate extended under the exit-pipe lto the back of the stove, leaving only the opening in front, represented:

by damper Z.

It is obvious ithat some of the improvements above described may be used separately, and that all need not necessarily be employed at the same time on the same stove.

' What Xve claim as new herein, and desire to secure by Letters Patent, is-

. 1. The air-heating chamber Gr G, at the base of the stove surrounding the ash-box, but not communicating therewith, with the openings H, for admitting fresh air, as described. 4

2. The pipo or Chamber A, admitting air, through the fuel, to the cap C, in combination with a concentratingplate, D, at the top of the tire-box, substantially as described. e

3. One or more ues, F F F, for conducting air from the base-chambcrto a point just below the plate D, as shown and described.

4.; The adjustable concentrating-plate D D', with the sliding doors E E', substantially as described.

5. The chamber, formed by plates I and L, and conical pots K and M, and forming a descending-llueior the purpose of conducting air downward to the top of the tire-basket, substantially as described.

G. The adjustable diaphragm L, in combination with the bottom of the conical pot K, substantially as described. i

7. The flue Q, in combination with the plate or diaphragm T, substantially as described.

8. The feeding-pipes R R or S, in combination with the fine Q, substantially as described.

9. The plate V, with the openings at the front and back, substantially as and for the purpose described.

10. The plate V, with the opening in front only, in combination with square or circular coal-stoves, sub stantially as described.

11. The plate Vf, in combination with the regulating-dampers Zl Z2, substantially as and for the purposes' described.
