TO ALL WHOM IT MAY QON CERN: Y

Be it known that I, ISAAC H. Grnounsnnuvs, of Whitewater, county of Walworth, and State of Wisconsin, have invented a newsnd useful Improvement in Bose-Burning, Gas-Consuming Coal-Stoves; and I do hereby declare that the following is `u full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of'this specifica.- tion, in which- Figure 1 is a perspective view.

Figure 2, vertical sectional view.

Figure 3, view of the upper side ofthe lower halt` of the grate. *t

Figure 4, sectional view of the bottom of the stove, draught-pipes, and grate.

Similar letters of reference in each of the guies indicate corresponding ports.

The object of my invention is to produce a stove with a magazine for coal, the burning of which shall be at the base,ewitl1 a downward draught, and so arranged that the re shall be easily and expeditiously kindled, and the gas escapingfromthe cool be entirely consumed, obtaining a. perfect combustion of fuel.

A, base of the stove; B, the outer shell 0,'inner shell; D, cover Ato the opening in the top of the outer slrell'; E, cover-'to Athe'op'er'in'gjiu th'e'top'of ythe inner shell, leading to the coal-magazine I, smoke-pipe; G,- door to the inner shell; H, door to the outer shell; I I, doors to the ash-pit, with openings for mica windows; K, re-pot; L, coal-magazine, with a. contracted opening at the bottom over theire-pot; M, dre-grate, made in two parts, with openings in its'several arms und rings for air to pass through to keep it cool, and to supply oxygen to the gas escaping from the coul, .to make perfect combustion. N1 N, air-pipes. Their lower ends open at the bottom of the stove for the entrance of air, and their upper ends open into the space between the inner shell and the tire-pot, for the aiuto pass through to support combustion ofthe coal. O, hollow pipe, its ends connecting with air-pipes N N. P, a. hollow thimble von pipe O, over which the grate M sets. At the buse of this thimble are'openings on each side of it, through which air passes from pipe O into and through the several air-passages in the grate. Q Q, dampers with which to close and open tho lower ends of pipes NN, to regulate the draught.. R, ash-pit; 'S S S S, openings for mica windows in the ash-pit door; T T T T, openings for mica. windows into the ash-pit from the back of the stove, These windows are for the purpose of showing .the blaze of the re as it descends below the grate. U, scrrationsin the periphery of the grate, to relieve thegrate when coal or clinkers get between the grate and the bottom of the fire-pot. V, an annular air-space in the grate Operation.

Coal is poured into the magazine M through the openings-in the top, which, passing down through itscontracted bottom, fills the fire-pot K. Coal may be poured'in till the magazine is filled, the coal at its bottom; resting on the coal in the iire-pot. Kindlings are the'n put-on the coul in the fire potaround itsedge, under the slope of the'maga'zino, and re applied tothem. This is done through doors G and H. Then doors G and H are closed, and dnmpers Q, Q are opencd';' air then Ypasses up through :tir-pipes NN to the lire, as indicsttedy by the arrows, andas there is no escape for it except down through the coal, to and through the grate, it takes that course, and passes out around the bottom ofthe inner shell C, and up between tho two shells, and escapes through. pipe F. This ignte's the coal, and il; burns from the top of the fire-pot to the bottom.

Air passes from pipes N N, through pipe O and thimble P., to the interirof the grate, and out through the openings therein, coming in contact in jets with the gas escaping from tlieburning coal, supplying oxygen enough to support combustion, and thus the gas is'consumed, und complete coinbustion obtained.

This cold air passing through tho grete keeps it suiciently cool to prevent it from being rapidly burned out by the beat. A

What I clairns my invention, and desire to secure by Letters Patent, is-

`from the coal, and to keep the gra-te from burning out, substantially :1s described.

A stove, consisting of base, A, outer shell B substantially as described.

2. Grate M, when made with air-spaces for air to innor shell C, pot K, magazine L, grate M, and pipes NN,

pass througl1,-for the purpose of consuming the gasos 3. Grate M, with a. serrated rim, substantially as doscribcd.
