GEORGE COPE, OF DETROIT, MICHIGAN, ASSIGNOR TO THE ART STOVE COMPANY, OF SAME PLACE.

COAL-STOVE.

SPECIFICATION forming part of Letters Patent No. 569,176, dated October 13, 1896.'

Application filed October 16,1895.

To 62% whom it may concern:

Be it known that I, GEORGE W. Corn, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement is a Base-Burner Coal-Stove; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention is designed to provide an improved base burner coal stove especially adapted and designed to provide a larger cold-air-heating-surface capacity than in previous stoves of this class, whereby more cold air can be taken into the stove and heated to a higher degree than in any baseburner heretofore on the market. I accomplish these results by a novel construction and arrangement of flues, enabling an extra large volume of cold air to be taken in at the bottom, to heat the same to a high degree of temperature, the air so heated being passed out at the top of the stove into the room. a

My invention also contemplates other features included in the general'construction, combination, and arrangement of devices hereinafter specified and claimed, and illustrated in the accompanying drawings, in

which- Figure 1 is a view in perspective, illustrating my invention, showing portions of the shell and other parts broken away to disclose the interior construction. Fig. 2 is a vertical cross-seotion through the base of the stove through the sides thereof. Fig. 3 is a partial rear elevation showing portions of the flues removed, parts also being in section. Fig. 4 is a partial horizontal section on the line 4 4:, Fig. 3. Fig. 5 is a horizontal section on the line 5 5, Fig. 3. Fig. 6is a longitudinal section on the line 6 6, Fig. 3.--\

I carry out my invention as follows:

A represents the outer shell of the stove.

B is the fire-pot within the combustionchambeT B.

The rear of the stove is provided with a' Serial No. 565,858. (No model.)

smoke-chamber C communicable with an elbow D and with the comb ustion-chamber, the smoke-chamber being provided with a damper C, which when closed divides the smokechamber C. I Communicable with the smoke chamber C are two smoke-fines E and E.

The base A of the stove is formed with a fiue E passing from the rear of the stove at one side around to the front portion of the base and rearward. The base of the stove is preferably cast with a dividing-wall A proj ectin g upward to and supporting a base-plate A There is thus formed a continuous flue in the base of the stove between the outer shell, the bottom, the wall A and the baseplate A from the rear of the stove around about the front portion of the base to the rear on the opposite side of the wall A The flue E leads downward from the smoke-chamber C, adjacent to the combustion-chamber, diversing to the right handof the stove, as viewed in rear elevation, and communicates with the flue E at the base of the stove. The flue E leads from the flue E on the opposite side of the wall A upward into the smoke-chamber C.

It will be observed that when the damper C is closed the products of combustion will pass from the combustion-chamber into the smoke-chamber C in front of the damper C, v

and thence downward through the flue E and about the base of the stove through the flue E thence upward through the flue E into the smoke-chamber C on the opposite side of the damper, and escaping through the elbow D.

Practically the flues E, E and E form one continuous flue downward from the smokechamber in front of the damper and about the base of the stove, and thence upward into the smoke-chamber at the rear of the damper. I

pass, if desired, directlyfrom the combustionchamber, through the smoke-chamber, into By opening the damper C the products of combustion may the elbow. The sin gle-headed arrows will indicate clearly the path or course of the products of combustion when the damperis closed. Above the base-plate A is the ash-pit, the ash-pan A being supported upon said plate.

A indicates a damper controlling communication between the ash-pit and the smokeflue E. The flues E and E are spaced one from another and from the side walls of the shell A adjacent thereto, affording an air passage or flue, as indicated at F, through which project the smoke-flues E E. The base of the stove is constructed with an opening A, communicating into the base of the air flue or chamber F.

At the upper portion of the stove the shell thereof is spaced from the magazine G to form a continuation of the air-passage F, said passage opening through the shell at the top of the stove to permit the exit of the heated air from the flue F to pass therethrough into the .room. The passage for the cold air entering into the flue F at the base of the stove and circulating upward in proximity to the flues E E, the back ash-wall A and about the magazine portion is indicated by the doubleheaded arrows. It is Well understood that heretofore the back ash-wall of the baseburner, as commonly constructed with the heat on both sides thereof, is liable to burn out quickly. In my improved stove, however, the back ash-wall has the air-passage F on one side thereof, by which the burning out of the ash-wall is prevented. By providing a large opening in the bottom a stove so constructed may take the cold air in thereat and pass it, as above explained, around and between the heated smoke-flues and about the magazine, whereby it comes in contact with a very large heating-surface and is passed out of the stove at the top thereof in large volume heated to a high degree of temperature.

It will be seen that the two smoke-flues E E depend from the smoke-chamber, the one to the rear of the other, leaving space between them and the shell laterally to form the flue F.

It will be seen that the shell of the stove extends rearward to embrace the smoke-flues and to form the flue F, already described.

What I claim as my invention is- 1. In a base-burner stove, the combination of a shell, a base provided with a flue E passing from the rear about the front and again to the rear, a combustion-chamber, a smokechamber connecting with the combustionchamber, a smoke flue leading from the smoke-chamber adjacent to the combustionchamber downward into one end of the flue E and an additional smoke-flue communicating with the other end of the flue E and with the outlet for the products of combustion, said smoke-chamber provided with a damper between the adjacent ends of the smoke-flues, said shell extending rearward to embrace said smoke-flues, said smoke-flues and shell spaced the one from the other and forming an air-flue between the flues and between the flues and shell, substantially as and for the purpose set forth.

2. In a base-burner stove, the combination of a shell, an ash-Wall, a base formed with a. flue E passing from the rear about the front and again to the rear, a combustion-chamber on one side of the ash-wall, a smoke-chamber, a smoke-flue separated from the ash-wall communicating with the combustion-chamber and with one end of the flue E and an additional smoke-flue communicating with the other end of the flue E and with the outlet for the products of combustion, said shell extending rearward to embrace the smoke-flues, said smoke-flues separated one from another and from the shell of the stove to form a hotair flue between the smoke-flues and between the smoke-flues and the shell, substantially as set forth.
