The products of comhustion can pass between these casing, L, composed of rooms.

' most apparent by comparing on-each side of the main and up the other two coVers -that is, between thctop of the feeder and under side of the plate X, thus imparting heat, which would be lost if the feeder extended to the said plate X and a single cover only were used.

In fig. 5 the line 5 represents the face of a wall, against which bears the arched plate or frame 6, figs. 1 and 8, and to the rear of this plate is secured a side plate 7' 7 and rearplateB, the side plates meeting the top plate 9, which is made fiat, as shown in the perspective view, fig. 8.

This casin g is fitted into the chimney-place L made in the wall 5, and forms the recess, into which one-half or there-abouts of the stove projects, a chamber being formed between the top plate X of the stove and the top 9 of the casing, for the heated air prior to its dis-. ttibution into the room containing the stove, or into the rooms above.

The pipe P passes through the top 9 of the casing into the due for conveying the products of combustion to the chimney-flue, and in the top 9 of the said casing is also an opening provided with a suitable valve or damper, 10, which may be so adjusted thatv the heated air shall be directed to the passage leading to upper rooms, or excluded from the said passage and projected outward into the room containing the stove; or the damper may be so adjusted that the heated air can be distributed both into the lower and upper When the valve 1: is closed the products of combustion will pass from the fire-chamber through the opening m, fig. 5, into the compartment 74;, thence down the pipe P into the passage F, fig. 3, along the passage F into the passage G, thence through the pipe P into the compartment k, and thence to the chimney. On opening the valve 1), however, the products of combustion will pass directly from the chamber 10, through the opening in the partition n, into the chamber k, and thence to the chimney.

The air admitted through the casing M at the rear of the stove into the chamber N is heated by intimate contact with the outer surfaces of these pipes P and'P', and by contact with the back of the casing I, before it passes oif through the opening X. I

Another and independent volume of air is heated in the chamber W, having been admitted thereto through the opening m in front of the stove, the air thus heated meeting the other volume of air and passing with the same through the said opening X.

Onthe top of that portion of the stove which projects into the room is a plate l-l, made in the form of a section of a hollow sphere, the plate which rests on the top plate X of the stove and against the wall 5 having openings for the passage of heated air into the room.

The main advantages of our improved stove will be it to the ordinary wellknown tire place stove,.of which a view on a small scale is shown in fig. 9.

In stoves of this class there are two pipes, to w, one

body of the stove, the prodnets of' combustion from which pass down one pipe to the chimney.

Owing to these external pipes the stove occupies an extended space, and is frequently too large for an ordinary himney-place; but by constructing a stove in the manner described, and by arranging the pipes for wall above the chimney-piece the passage of the products of combustion to the chimney within the stove itself, the latter may be made of aconvenient'size, and this without any loss of heat. Moreover, our improved stove can bearrangedto project further into the room than ordinary fire-place stoves, and, consequently, the room is more thoroughly heated than when the stove is moved far back into the fire-place.

Another advantage of our improved stove is the situation of the pipe 11' for the escape of the products of combustion, this pipe being conveniently arranged for direct communication, without elbow-pipes, to the flue of the chimney.

' In ordinary fire-place stoves it is usual to supply the magazine with fuel from the front, an arrangement which demands a short magazine.

By introducing the fuel through the top of the stove a deeper magazine may be used, and this long feeder enables us to form an air-chamber, W, which greatly increases the heating properties of the stove.

Another important feature of our invention is the formation of a general hot-air chamber between the top of the stove and the top of the casing, so that this air may pass directly outward into the room immediately above the stove, thereby dispensing with the hot-air register, which has been usually placed in the of a fire-place stove.

The valve or damper I0 is another valuable .improvemeut, whereby the heated air may be directed to or excluded from the upper room without the necessity of going to that room for the purpose of adjusting the registers therein.

Claims. stove inclosing the passages F, and G, arranged and communicating with pipes or passages P and P, substantially as described.

2. Two or more pipes or passages, P and P, arranged within the outer casing of a fire-place stove for conveying the products of combustion to the chimney and for heating the air admitted to the space within the said outer casing, all substantially as and for the purpose herein set forth.

3. The said pipes or passages P and P, in combination with the compartments in and k and the valved partition between the same.

4. The doublecover, consisting of plates 2 and 3, ope for fitting to the top the top of the feeder, and so arranged that the prodnets of combustion can pass between them.

5. In a fire-place stove, a valve or damper, 10, arranged, substantiallyas described, so as to direct the heated air into the passage leading to an upper room or rooms, or" to exclude the heated air from the said passage and direct it across the the room containing the latter, forth.
