IIESPERE 'sEEEBRIAKoFn oF PARIS, FRANCE.

SLOW-COMBUSTION STOVE.

SPECIFICATION forming part of Letters Patent No.510,-'714, dated December 12, 189,3.

Application tiled June 12, 1823. Serial No.. 477,346. (No model.) Patented in France October 3, 1892, No. 224,694; in Belgium October 3, 1892, No. 101,585, and in England October 18, 1892, No. 18,636.

To all whom it may con/cern,.-

Be it known that I, HESPERE SEEEBRIA- KOFF, a subject of the Emperor of Russia,'and a resident of Paris, in the Department ofthe Seine, France, have invented a new-andus'eful Improvement in Slow-Combustion Stoves, (for which I have obtained patents in France, No. 224,694, dated October 3, 1892; in' Belgium, No. 101,585, .dated October 3,' 1892, and in England, No.'18,6'36, dated October`18, 1892,) of which the following is a specification,

This invention relates to an improved economical and slow combustion stove which is capable ot' being arranged as a fixture, or may be vmounted upon wheels, so as to be portable, and readily moved about from one room to another.

In order that the invention may be readily understood I have shown,by way of example, in the accompanying drawings, a portable stove constructed in accordance therewith.

Figure 1 is an axial section of the stove taken on the line A, B, of Figs. 2 and 3, and Figs. 2 and 3 are transverse sections of the same taken respectively on the lines C, D, and E, F, of Fig. 1.

. This stove consists -of the'foilowing parts, viz: two vertical concentric cylinders ofv circular or polygonal section, and composed of asbestus iron, the composition of which material will be hereinafter indicated; a fire place composed of refractory bricks; an iron fuel reservoir lined with refractory clay; ani

ash pan or tray having a regulator; a pipe having a regulator.

The cylinders 1 and 2 are made of asbestus iron; that is to say they are each composed of three superposed layers, an inner layer of iron and two outer layers of asbestus, the distance between the two cylinders being at least one-fourth inch.

The tire place 3 is located within the cylinder 2, and is composed of several superposed annular bricks. Its lower portion consists of an annular refractory piece or block 4, the inner walls of which are formed as a truncated cone, and provided with lateral holes or

passages

5, 5, arranged at different levels, and in various directions. A space of at least one twenty-fourth of an inch is left between this annular piece and the inner wall of the cylinder 2. This first ring 4 is surniounted by a second ring 6,which fits closelyagainst the inner wall of the cylinder 2, and is formed, at its lower part, with a deep channel 7 having is upper side pierced withvertical holes 8, 8. The succeeding annular bricks 9, 9, which are thinner, are situated one above the other, and the wall of the last or.. uppermost one is reduced in thickness, on one side, and cut away on the other. A brick 'or asbestus iron partition or diaphragm caps the series.

The inner .cylinder 2 is provided With aseries of holes 11 on a level with, and inl front of, the cnt away portion of the'last or uppermost brick,said holes enabling the gases to enter thespace between the two cylinders 1, 2, byfollowing the course indicated by the arrows. ,i

The fuel reservoir 12 is an iron cylinder lined with refractory clay or bricks and descends as far as the annular piece, block, or

brick 6.

The two cylinders .1, 2, are cutaway at their lower parts for the reception of the ash-pan 13. The outer cylinder receives the pipe 14 through which the gases of combustion escape. These two cylinders are connected and held together by means of two iron or

steel plates

15 and 16 which are lined with alayer of asbestus and clay. The upper plate 15 1s provided with a central hole which is closed by means of a cover '17. Wheels 18 may be itted tothe lower plate.

The ash pan 13 consists of an iron or asbestus case, which,when in place, hermeticallycloses the front opening, and it is fur-y nished with a regulator 19 on its outer face to enable the entry of air to be regulated. The pipe 14 is also furnished witha regulator 20, in the form of a valve, or butteriiy, for

regulating the exit of the gases of combus- IOO in the' regulator 19, into the ash pan, passes throughthe grategand through the holes or passages 5 into the replace, where it supports combustion. The gases of combustion filllng the circular channel 7, rise up through the holes 8, pass through theholes ll into the space between the two cylinders, which they ll, and finally escape through the pipe 14 to the chimney.

What I claim; and desire to secure by Letters Patent of the United States, is

1. In a slow combustion stove, a fire-place formed of superposed sections, or rings, of fireclay, an annular passage communicating with .the upper part of said [ire-place, ahollow casing formed of two concentric cylinders of asbestus iron arranged outside of said annular passage and fireplace, `the inner cylinder having passages for the escape of the gases of combustion from the upper end of said annnlar passageinto the hollow casing, and a pipe tocarry off the products of combustion, substantially as described.

2. In a slow combustion stove in whichvthe fireplace is built up of superposed fireclay sections, or rings, the construction of theV lowerinost one with its upper part enlarged on its interior, and formed with lateral holes or passages, and the section or ring immediately above it formed with a circular groove or channel having vertical holes orperforations through which the gases of combustion pass from the grate to reach the space between the double casing, substantially as described and shown.

3. In a slow combustion stove, the combination withfthe iireplace built .up of superposed fire-clay sections or rings, andsurrounded by a double casing of asbestus iron, of a centrally located fuel reservoir adapted to be lclosed with a tight tting cover and passing through partitions situated above the tire place, said fuel reservoir being so disposed as to leave a space for the ascending gases of combustion to reach openings leading into the space between the casings and, after circulating therein, to reach the chimney, substantially as described'and shown.

4. In aslow combustion stove, a fire-place fornied of super-posed sections or rings of {ireclay, an annular passage for the products ot combustion Vhavingitslower. end inA communication.` with the nre-place, al surrounding hollowcasing formedlot twoiconcentric cylinders of asbestus iron, theinnercylinder'providedl with openings to permitthepassageof the productsof combustion from the top of the annular passage into the-hollow casing, a tight-fitting ash-pan having a` regulator for controlling the entrance` air, and a pipe to carry oit theprodluctsofcombustion, substantially as described.

In testimony whereof I` have signed" this speciication in the presenceiof two subscribing witnesses.
