LUTHER W. CAMPBELL, OF AURORA, ILLINOIS.

COAL-STOVE.

Specification forming part of Letters Patent No. 551., [43, dated November 28, 1865.

To all whom it may concern.-

Be itknown that I, LUTHER W. CAMPBELL, of Aurora, in the county of Kane and State of Improved Stove and 1 do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanyin gdrawin gs, and letters ot'reference marked thereon, making apart of this specification, in which Figure 1 is a perspective representation of my improved stove. Fig. 2 is a vertical central section of the tire-box.

The nature of n1y invention consists in providing a'convenient stove for burning coal'or wood insuch a manner as to have the combustion take place on the largest surface possible, or around the outside of the fuel, and in pro iding hot-air flues continuously around the inside of the firebox for consuming the gas rising from the coal; also, in enlarging the [irebox at the bottom andmaking a cone-shaped grate for carrying out the object of the invention. v y

That others skilled in the art may make and use my invention, I will describe the method of constructing and using the'same.

First, as a foundation to which'l attach my improvement, I use any of the common bases or ash-boxes now in common use for the bottoms of stoves, but prefer the square pattern represented in the drawings,as shown at Fig. l by the letter A, and to the top of the ashbox or base of the stove A, I attach, by any of the common methods, the firebox B, and to the top of the fire-boXB, by means of the flange or rim U, I attach the drum (J.

Atl'), Fig. 1, is shown the stove-pipe, which is connected with the ash-box A in the common manner, and to the drum 6 by means of the horizontal pipe E.

At S and R are shown the damperspvhich are used to chauge the current of draft.

P'representsthc crank used in stirring the coal that rests upon the grate, and is used in the usual manner.

' F represents thedoor in the drum Gpthat is used in the same manner as in other stoves when putting fuel in the fire-box G.

The fire-box B, the inside of which is shown at G, I construct'wholly on a new plan, by inclosing the same with a series of hot-air flues, as n n n, 850., represents, and extend them from the top of the fire-box downward one halt' to three-fourths of the height of the same, thus giving a greater distance between the sides of the fire-box below'the flues n, as shown at M M, Fig. 2, than between them.

At t i, 850., Bi g. 1, are shown small grooues or openings leading from the inside of the tireof the fire-box at a: and turnthe same inward through the tines n. r

In constructing the fire-box the outside of the same, as shown at B, is not essential, only' as a matter of ornament or convenience. The, fire-box will answer every purpose without it.

The material used in the manufacture of the tire-box is the same as that generallyapproved in the construction of other stoves, the part M being of cast-iron, and the lines a can be made of the same material, which is preferable; but they can be made ofany fire-proof composition used forsuch purposes. V

Operation: First, any kind of fuel can be used in the same manner as in otl er'stoves, but my improvement is especially adapted to the burningof Illinois coals, or any other kind that gives imperfect combustion. In lighting the fire the outside of thecoal should be ignited first, as the tines will then carryoii" all the gases not possible ,to consume-211i this precaution is taken the fire-box can be filled to the top of the lines without any possibility of obstruct ing the draft. The darts 2 in the enlarged part of the firebox show the direction of the draft through the lines a.

Now, havingdescribed my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

A. fire-box for a stove, containing the flues a, cap XV, parts M, as set forth.
