IMPROVED COOKING-STOVE.

ESpeciiication forming part of Letters Patent No. 45,432, dated December 13, 1864.

To ctZZ whom, it may concern:

Beit known that I, MosEs POND, a resident ot' Boston, in the county of Suffolk and State ot' Massachusetts, have made a new and useful invention of certain Improvements in Cooking- Stoves; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 denotes a longitudinal and central section of a stove provided with my invention. Fig. 2 is a transverse section taken through the fireplace. Fig. 3 is a transverse section taken through the oven. Fig. 4 is a transverse section taken through the back tlue dovetail plate or partition, and representing the arched slantin g plate at the bottom thereof. Fig. 5 is a front end elevation, and Fig. 6 a side elevation, of the stove. Fig. 7 is a transverse section of the fire-place audits lire-brick lining, such section being taken through one of the air heating and receiving chambers applied to the front plate. Fig. 8 is a rear view of one of the end parts of the fire-brick lining.

The nature of my invention consists of an improved lire-proof lining or linings to the replace, the same having a channeled, recessed, or chambered back, substantially as hereinafter described; also, in the arrange ment and combination of a separate air-heating chamber with the tire-place and oven of a cookingstove in such manner as to surround the fireplace and be capable of receiving air from the external atmosphere and heating it and afterward discharging it into the oven, the said airlheating chamber having not only one or more air-induction passages leading into it, but one or more aireduction passages leading from it into the oven also, in the combination and arrangement of one or more air-,heating chambers with the front plate ofthe stove, and with the oven and the chambered lining or main airheating chamler, and the passages for leading air into and through the said chamber or chambers and li dug and into the oven; also, in the combination of a slanting arched plate at the bottom ot' the dividing back iiue plate with such ilue plate, and the curved partition leading underneath the oven, as hereinafter described, the purpose of the slantin g arched plate being to enlarge the oven-tlue, so as to increase the l B the grate, O the ash-chamber, and D the oven, ot' a stove, they being arranged together as shown in Fig. l.

The fireplace has a lire-brick, stone, or other suitable lining, E, which in its rear surface is to be chambered or recessed, as shown at a, the chamber a being horizontal, and extending throughout each side and end portion of the lining. One or more air-holes, b, made through the front plate,c,of the stove lead air into the chamber a of the lining, which, after having circulated about the lining or between it and the plates of the stove, will escape into the oven by or through one or more orifices, c', made through its front side. The holes b are covered by, one or more guard-plates, d, which are so applied to the front plate of the stove as to form between it and such guard plate or plates one or more auxiliary air heating chambers or channels, c, open at bottoln. The air rushing upward into such auxiliary chamber or chambers e will become more or less heated therein before passing into the induction hole or holes b. Thus, while these auxiliary chambers c serve to heat the air, the plate or plates d act as guards for the induction-holes and to prevent heat radiated from the front plate ot' the stove from being an inconvenience to an attendant while standing or stooping immediately in front or close to the stove.

Over the top plate of the oven there is a line, F, which also descends in rear of the oven, as shown at F', and opens into ues G Gr, which course directly underneath the oven and from the rear to the front thereof, such tlucs being formed in part by an arched plate, IzI, which is extended underneath theoven and rests at its two opposite edges on the bottom plate, I, ot' the stove. With such bottom plate the arched plate forms a return-due, K, which at its rear leads into an ascending discharge-line, L, (formed by the back plate, f, of the stove and a dividing back line plate, 9,) and at its front opens out of the flues G G.

The junction of the plates H and g is effected by a slanting arched plate, k, arranged as shown in the drawings, such slanting plate k serving the purpose or purposes hereinbet'ore stated. An opening, l, in the upper inclined part ofthe plate g is provided with a damper, m, suoli opening being for the purpose of dis- I charging the smoke into the escape-flue Without rst causing it to circulate against the rear and bottom of the oven.

In the operation ot' the above described stove the air which goes through the recesses or chambers of the lining serves to `absorb heat from the lining, and thereby prevents such lining from becoming overheated.

I claiml. The improved stove as madewith the nir- Witnesses:
