KlLN FOR BURNING POTTERY-WARE AND OTHER ARTICLES.

SPECIFICATION forming part of Letters Patent No. 233,230, dated October 12, 1880. Application filed March 4, 1880. (No model.)

To all whom it may concern:

Be it known that I, WLLLIAM FRENCH, a subject of the Queen of Great Britain, residing at New York, in the county and State of New York, have invented new and useful Improvements in Kilns for Burning Pottery-Ware and otherArticles, of which the following is a specification.

This invention relates to a kiln which is composed of a circular burning-chamber, a series of fire-places arranged on the periphery of a circle below the bottom of the burning-chamber, a central flue opening into the burningchamber, a series of radiating-fines extending from the fire-places to the central flue, a circular flue situated beneath the bottom of the burning-chamber, a series of vertical fines extending from the burning-chamber to the circular flue, and a smoke-flue leading from the circular flue to the chimney, so that the heated gases which rise from the tires in the fire-places pass through the central flue up into the burning-chamber, and after having circulated through said burning-chamber they escape through the central flue to the chimney, and thereby the articles in the burning-chamber are heated uniformly and with great economy in fuel.

With the parts above stated are further combined a series of fire-bags, one for each fireplace, and communicating with the same through vertical lines extending up close to the circular wall of the fire-chamber, and an opening in the top of said fire-chamber, which can be opened or closed by a damper for the purpose of regulating the heat in the burningchamber.

This invention is illustrated in the accompanying drawings, in which- Figure 1 represents a vertical central section. Fig. 2 is a horizontal section in the plane a: .r, Fig. 1. Fig. 3 is a similar section in the plane 3 y, Fig. 1. Fig. 4 is a similar section in the plane 2 z, Fig. 1.

Similar letters indicate corresponding parts.-

In the example shown in the drawings, the letter A designates the burning-chamber of my kiln, which is built, by preference, in a circular form, but which may be polygonal or of any other form suitable for the purpose. A door, B, gives access to the burning-chamber, and below the bottom of said burning-chamber are a series of fire-places, G, which communicate, by radiating-flues a, with a central line, I), leading up through the bottom of the burningchamber, and below the radiating-fines a is a circular flue, c, Fig. 4., which communicates with the burning-chamber through a series of vertical fines, d, extending up between the radiating-fines, as shown in Figs. 2 and 3, and from said circular flue 0 extends a smoke-flue, e, to the chimney D.

From the bottom of the burning-chamber rise a series of fire-bags, E, one over each of the fire-places O, and situated close to the inner wall of the burning-chamber, as shown in Figs. 1 and 2 of the drawings. From each fireplace rises a vertical flue, f, into the corresponding fire-bag E, and in the top of the burning-chamber is an opening, 9, which can be closed or opened by means of a damper, h, Fig. 1. After the articles to be burned have been placed into the burning-chamber A the door B is firmly closed and fires are started in the several fire-places (l. The heated gases from the fires pass up into the burning-chambers, partly through the central flue, b, and partly through the fire-bags E, and after striking the top of the burning-chamber they are turned downward, and escape through the vertical fiues cl, circular flue c, and smoke-flue 0. By these means the heat is uniformly distributed throughout the burning-chamber, and the articles contained therein are burned uni- .formly, with great economy in fuel. It must be remarked that in order to accomplish this purpose the fire-bags E and flues f might be closed or omitted, since a uniform distribution otheat in the burning-chamber will be effected by the cooperation of the radiating-fines a, central flue, b, vertical flues d, circular flue c, and smoke-flue e.

If the heat in the burning-chamber rises beyond the desired point, I open the damper h, and

the heated gases pass straight up from the fire 5 10 ing-chamher through vertical flues intermediate of the radiating-fines, substantially as and for the purpose specified.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.

WILLIAM FRENCH.
