BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 463,167, dated November 17, 1891.

Application filed April 30, 1891. Serial No. 391,104. (No model.) i

To 00% whom it may concern.-

Be it known that'we, EDWARD M. PIKE and .IUsTUs CASTLE, of Chenoa, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Tile and Pottery Kilns; and we do declare the followingto be a full, clear, and exact descrip:

-ters and figures of reference marked thereon,

which. form a part of this specification.

Our invention relates to improvements in kilns for burning articles of clay, earthenware, &c.; and it has for its object to so im prove the existing prior state of the art that there willbe produced a kiln which will burn quickly, uniformly, and thoroughly the articles placed therein, combining efficient Work with expedition and economy.

To this end the invention consists in the novel construction and arrangement of the several parts, as will be hereinafter more particularly described, and specifically pointed out in the claim.

WVe have fully and clearly illustrated our invention in the accompanying drawings, to.

which reference is had and which form a part of this specification, wherein Figure l is a central vertical sectional view taken on the line x as of Fig. 2, and Fig. 2 is a horizontal sectional view of the furnace. Fig. 3 isa perspective view showing the floorframe and bands which encircle the kiln. Fig. 4 is an inside view showing the flooraud arching, and Fig. 5 is a section of arching.

A designates a downdraft kiln of ordinary size constructed of the usual materials.

B represents the fire-chambers formed in the lower walls of the kiln equally distant from each other and between any two of which the door may be placed. The walls at the point where the fire-boxes are located are formed thicker than at the top of the kiln.

0 represents flues extending from said fire around the entire kiln on the inside at a.

proper distance from the walls, arched over a distance from the stack side, and connecting with the transverse flue G at both sides of the kiln and with the crossflues F, and thence with the stack.

L represents the door-frame, preferably constructed of iron, and M designates a series of metallic bands designed to strengthen the walls by encircling them on the outside,

and being held together by couplings when they do not quite meet.

Inasmuch as the heat invariably inclines toward the draft side, by arching over the annular flue E and the transverse flue G the heat is thrown in the opposite direction from the stack and secures a perfectequalization and distribution of the drafts, which cannot otherwise be done, and this feature forms a very important part of this invention.

Having thus described our invention, what we claim is- A kiln for burning earthenware material, clay, due, having a series of cross-fines extending the entire width of the kiln, a transverse flue extending the entire width of the kiln diametrically opposite to the cross-fines and partially arched over, and an annular or circular flue extending entirely around the kiln on the inside and partially arched over, all of which flues connect, substantially as described. i I

In testimony whereof we affix our signatures in presence of two witnesses.
