GAS-FURNACE.

SPECIFICATION forming part of Letters Patent No. 620,052, dated February 21, 1899.

Application filed October 27,1898. Serial No. 694,722. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES W. RICE, of Columbus, in the county of Franklin and State of Ohio, have invented a new and Improved Gas-Furnace, of which the following is a full, clear, and exact description.

My invention relates to an improvment in gas furnaces and stoves used for heating purposes, and comprises the novel features hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of my furnace on the line 1 1 in Fig. 2. Fig. 2 is asectional plan taken upon the line 2 2 in Fig. 1. Fig. 3 is a sectional elevation on the line 3 3 in Fig. 4 of a stove built upon the same principles. Fig. 4 is a sectional plan taken upon the line 4 at in Fig. 3. Fig. 5 is a sectional elevation on the line 5 5 in Fig. 6 of a slightlymodified form of stove, and Fig. 6 is a sectional plan on the line 6 6 in Fig. 5.

My stove or furnace is designed for use in connection with gas, and contains a central combustion-chamber A, made in the form of a cylinder, preferably slightly reduced in diameter at its upper end and having a gasburner E located in the lower. part thereof and supplied with gas through pipes E, which extend laterally outside of the furnace or stove. An opening is made in the lower part of the combustion-chamber for the introduction of air and to permit examination of the.

burner. I This opening is connected by means of a pipe a with the outer casing O and is provided with any suitable door by which it may be closed when desired.

The combustion-chamber A extends up ward through the bottom of the body B of the furnace, which consists of a cylinder extending a short distance above the upper end of the combustion-chamber A. From the roof of the main chamber B is suspended, by means of bolts 9, a deflecting-plate G, which is of somewhat greater diameter than the upper end of the combustion-chamber and deflects the current downward and about the combustion-chamber. It also forms an easilyrenewable member, which receives the most intense heat of the flame, and thus protects the top or crown sheet of the furnace proper. When this plate has been destroyed, another may be cheaply substituted. Above the up per end of the bodyB is a drum F, which, as shown in Fig. 1, is supported a short distance above the end of the body B by means of short legs f, so as to form an air-space between the two. As shown in Fig. 3, the upper end of the main chamber or body B forms the lower portion of the drum. Said drum is connected with the lower portion of the body of the furnace by means of pipes D, which extend outside of the body and are disposed about the same in any convenient manner. The number of these pipes will vary according to the capacity of the furnace. In Fig. 5 these pipes are shown as directly connecting with the smoke pipe or flue H, the lower end of which, H, rests upon the top wall of the body B, so as to receive heat thereform by transmission, said lower end H being thus an equivalent of the drum F. In the other cases the smoke-pipe H is shown as connecting directly with the upper portion of the drum F. The smoke-pipe H is provided with a damper h by means of which the circulation may be regulated.

As shown in Figs. 1 and 2, the entire furnace is surrounded by a casing O, which is provided with openings J in its lower portion for the admission of air and has pipes I connected with its upper portion for conveying the heated air to any point desired. In the forms shown in Figs. 3 and 5, which are designed more for use as stoves, the body of the furnace is supported upon legs L, which rise to a short distance above the floor. This form of stove or furnace will extract a large proportion of heat from the gases and is very economical in the use thereof. In Fig. 1 is shown at K a reducer, placed in the smokepipe near the chimney and consisting of a cone of sheet metal, its larger end being toward the furnace and filling the pipe. The product of combustion in furnaces using natural gas or other similar fuels is largely water, which is in the form of steam in the furnace. A comparatively very small pipe is sufficient to carry this away, but a somewhat larger pipe than actually necessary is desirable for its increased radiation and better appearance. By using the above reducer the larger pipe may be used and the reduction of size be accomplished, which keeps the pipe hot and prevents the steam condensing and dripping from the joints, which otherwise would be a cause of much trouble.

It will of course be understood that the reducer K may be used in the smoke-pipe H of any one of the stoves or furnaces shown.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the combustionchamber tapering toward its upper end, the main body surrounding said combustionchamber and communicating therewith at the top only, the drum located on top of the main body in metallic contact therewith so as to receive heat by transmission, the pipes connecting said drum with the lower part of the main body, and the smoke-pipe connected with the drum.

2. The combination of the upright combustion-chamber, the main body having a closed top and surrounding the combustionchamber at a distance so as to form an annular cham her, the two chambers communicating at the top only, and the side wall of the main body being apert red circumferentially near its bottom, the drum located on top of the main body in metallic contact therewith so as to receive heat by transmission, said drum being apertured peripherally, pipes connecting the apertures of the main body with those of the drum, and the smoke-pipe connected with the drum.

3. The combination of the upright combustion-chamber, the main body having a closed top and surrounding the combustion-chamber at a distance so as to form an annular chamber, the two chambers communicating at the top only, and the side wall of the main body being apertured circumferentially near its bottom, the deflector depending from the top of the main body and extending outwardly beyond the upper end of the combustionchamber at a distance therefrom, the drum located on top of the main body in metallic contact therewith so as to receive heat by transmission, said drum being apertured peripherally, pipes connecting the apertures of the main body with those of the drum, and the smoke-pipe connected with the drum.

4. A furnace having a cylindrical main body, a cylindrical combustion-chamber extending upward within and to near the top of the body, a deflecting-plate suspended from the crown of the main body and covering the upper end of the combustion-chamber and at a short distance therefrom, said deflectingplate having its edges curved downward, a drum supported above the furnace-body, but out of direct communication with the upper part of such body and a series of fines connecting the drum with the lower part of the furnace-body, substantially as described.
