IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 164,789, dated June 2.2, 1875 appl cation filed March 13, 1875.

" and State of Illinois, have invented certain new and useful Improvements in Combined Cooking, Heating, and Air-Girculatin g Stoves;

and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form a part of this specification.

My invention consists, first, in the constructiori and arrangement of the hot-air lines, so that they may be used not only for heating but also for ventilating purposes; second, in so arranging said fines that two different rooms may be heated or ventilated alternately and, third, in so constructing and arranging the cooking-chamber that it shall-be surrounded on the sides and top by the hot air and products of combustion, all as hereinafter more fully shown and described.

On the drawing, Figure 1 represents a vertical section of my improved stove; Fig. 2 is a horizontal section, in the plane indicated by the line 00 m in Fig. l and Fig. 3 is a horizontal section of the top part of my improved stove, in the plane indicated by the line y y in Fig. 1.

Similar letters of reference indicate corresponding parts in all the figures".

A is the magazine, or fire-chamber, which is provided with a door, a, in front, by which the draft is regulated, and is surrounded, on the sides and back, by a closely-fitting screen, N, by which the intermediate air-chamber M is formed. It will be observed that this airchamber surrounds the magazine, where the combustion takes place on all sides, except the front side, where the door is. Air is admitted into the air-chamber M from the receiving-chamber W, located under the bottom of the magazine,- through an opening, m, back of the magazine. From M the air ascends,

through the openings 0 and 19, (see Fig. 2,) up into an air-chamber which surrounds the cooking-chamber Q on the sides, and then passes up through the triangular hot air flue T, from which it is emitted out into the room where the stove is placed through the valve or register U, which is operated by turning the vase on the top of the stove. The magazine A is supplied with fuel through a door, B, opening into the cookin g-chamber Q, by removing a'plate or cover, denoted by c, which is replaced when the magazine is full. The chamber Q is provided with one or more potholes in the bottom-plate, into which pots, pans, or kettles may be placed, and the door Bmay be left open or closed at will. The products of combustion (smoke, &c.,) pass through the flue D up into the flue S, back of the cooking-chamber, and then up into the fine E. This partofmyimproved stove is constructed by inserting three metallic plates vertically through the cylindrical top, thus forming three fines surrounding the central triangular airflue as shown in Fig. 3. Inthis figure, drepresents the outside casing or cylindrical body of the stove. b b b are the plates, inserted vertically through the body. E, F, and G are the smoke-fines, and T is the central triangular airline, which is surrounded on all sides by the heated plates b b and b From Sthe smoke passes up into the flue E, then through an opening in the top of the plate I) (at so) into the flue F, then through an opening in the bottom of plate b (at'y) into the flue G, and then up through that flue and out intothc smoke-chamber on the top of the stove. By

this arrangement the heat carried ofl in the products of combustion is utilized for heating the air in T, besides warming the surrounding outside cylinder; and no heat is lost in heating up surface or parts that do not come in direct contact with the air to be heated. The smoke, after passing up through G, emerges out into the smoke-chamber I, and

then passes out through the stovepipe K into the chimney.

1 have already stated that the air to be heated is taken from the receiving-chamber W, under the ash-pit b. It finds its way into this reservoir through three different channels. In the first place, if it is desired to heat the air of the room in which the stove is placed without introducing new air from without, the valve L (see Fig. 1) is opened, and the valves 3 and v (the latter in another room) are closed,

,FFIGE.

The cold air in the room, which is alwaysnear the floor, enters W by L, then passes through the hot-air chamber M, as already described; then up and round the chamber Q, by way of the openings 0 and 19 (Fig. 2,) then up through the triangular flue T, and again out into the room through U.

When the room has been heated sufiiciently,

. and itis desired to heat the neighboring room,

outside enters the reservoir W. After being I heated, this air may be'let outin either room,

by opening either at U or at or or the-valves on the top may be so regulated that it may be emitted, simultaneously into bothrooms. Suitable arrangements are made for-carrying off the bad or cold air in the room or rooms thus supplied with fresh air from without.

It will readily be perceived that myinventiou,

in its several bearings, is susceptible of modidrawing; but

What I claim, and desire to secure by Let- -fications,v and I do not, therefore, limit myself to the precise form of stove shown in the ters Patent, is as follows:

1. The combination of the reservoir W, for

the-reception of cool air, with the heatingchamber M, and hot-air flues 0, p, and T, substantially as and for the purpose shown and described.

2. The combination of the triangular hot-air flue T, with the surrounding smoke-conductin'g heating-flues E, F', and G, formed by the :plates 1), b and 12 having perforations at w y, substantially in the manner and for the purpose specified. I

3. In combination with the triangular hotair flue-T, surrounded by the smoke-conductling heating-flues E, F, and G, the valves or registers. U 00, arranged and operating substantial-ly as and for-the purpose. specified.

In testimonythat I claim the foregoing as my own, I have hereunto affixed' my signature in presence of two witnesses.
