IMPROVEMENT IN HEATING-STOVES.

Specification forming part of Letters Patent No. 56,979, dated August 7, 18,66.

To all whom 'it may concern.- 4

Be it known that. we, GRANVILLE MooDY and WILLIAM P. HALL, both of Piqua, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in Stoves; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Like letters refer to the same parts of the stove in all the figures. i Figure l is a front view of a stove contain ing our improvements, -with the lower doors thrown open and the upper door removed. Fig. 2 is a cross-sectionthrough the line :c y, Fig. l. Fig. 3 is a view of one end of the stove with the outer plate removed. Fig. 4 is a view of' the opposite end with the outer plate removed.

A is the front outer plate of the stove, A' the back plate, B the bottom plate, and B' the top plate. C C' are two inner plates parallel 'to the outer end plates, and c, c', el, and e3 are partition plates extending from said inner plates, O C', to the outer end plates, and forming ues at each end of the stove.v D D D2 are internal plates extending from the plate C t0 the plate C', and forming a hot-air chamber, E, between said plates C and C'. F, F', F2, and F3 are openings in the inner plate, C', communicating with the end iiues, and f, f', f 2, and f3 are openings in the plate G for similar purposes. G is a horizontal plate extending from the plate C to the plate C', and G' is a movable vertical plate forming the back wall of an oven or hot-air chamber, H. g g' are two rods for. moving the plate G'. I is a damper and scraper, and 'i llare rods for operating, the same. H' is thelront door to theoven or hot-air chamber E, and J J are the furnace-doors. Kis an inclined plate forming the back wall of the re-box'f'or furnace. L is the grate hinged to said in .jeined plate K, and

heated air to the tire, to aid iu the complete combustion of the smoke andgases. A similar row of perforations, n', is madein the front portion of said bent plate as vents forheated beused as an oven to bake or roast in, or as ahot-air chamber from which heated air may be conducted through the exitpipe O to an upper or an adjoining room.

P is an oval opening in the bottom plate of the stove to admit air into the chamber K',

and from said chamber K' the air, after becom-v ing heated therein, passes out at the opening f3, up the flue S', and into the chamber E through the opening fz. ture in the bottom plate, to admit air to the iiue T, whence the air is conducted, through the opening F3, into the chamber N'. R is an opening in the bottom plate to .admit air into the flue S, in which it becomes heated in ascending, and passes -into the oven or hotair chamber H. F2 is an opening in the plate C', through which the heated air from chamber E passes into fine T', and from said iiue, through the opening F', enters the oven or hot-air chamber H.

j By adj ustingthe movable plate G' the heated air escaping from' chamber' E maggr be conducted into the oven H, or maybe conducted off through the pipe O without entering the chamber H.v This will be the case when the plate G' is in the position shown in the draw ings; but if the plate G' be drawn back to the line o all the air escaping from chamber E v must enter the oven or chamber H.

It is manifest that said plate G'may be so adjusted that part of the air escaping from chamber E Will enter the chamber H, and part pass out of the pipe O without entering said chamber.

When the plate GJ is in the position shown in the drawings, and the register M closed, the heated air from chamberH will pass out at opening f and reach the exit-pipe O through Openingf Q is a smaller aper Y hard or soft coal or wood, tbe air in chamber N' will immediately become rarefed and cause an ascending current through the opening Q, up the flue T, and through the opening Finto said chamber N', from which it will escape e through the perforations u into the combustion-chamber above tbe grate; By means of the bail or pawl l and the ratchet Z the fuel in the grate may be brought up nearer to said jets of heated air, or removed farther away from the same, according to the nature of the fuel used. The flame and other products of combustion will pass up the vertical flue w, along the horizontal ne w', and out at eXit pipe O', acting immediately upon the plates D D D2, forming three sides of the chamber E, which will cause the air in said chamber to become highly heated and to escape through the opening F2, ascend through the flue T', and either enter the chamber H through the opening F or pass out of the exit-pipe O, ac

cording as the movable plate G may be adjusted. At the same time the cold air will;

rush in through tbe opening P in the bottomi plate, pass into the flue S' through the open 'f' ing f3, and enter said chamber E through the' opening f2.

Having thus fully described our invention; and the mode of carrying it intoe'ect, what we claim as new, and desire to secure by Letters Patent, is-

l. The lower bot-air chamber,E, in c0mbination with tbe upper betfair chamber or 0ven,l H, with a liuc and air-passage, for conducting heated air from the lower to the upper chamber, substantially as shown and described.

2. In combination with the hot-air chamber N and the perforations n. the hinged adjustableY grate with the bail or pawl l and the ratchet l', substantially as shown and described.

of a'damper and scraper, substantially as described.
