GEORGE HOWES, OF KANSAS CITY, MISSOURI.

KILN FOR BURNING SEWER-PIPES.

' SPECIFICATION forming part of Letters Patent No. 374,678, dated December 13, 1887.

Application filed May 31. 1887. Serial No. 239,75s. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE HoWEs, a citizen of the United States, residing at Kansas,

Oity,.in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Kilns for Burning Sewer- Pipe; and I do hereby 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.

My invention relates to an improvement in kilns for glazing and burning sewer-pipe and the like; and the objects of the invention are to economize fuel and at the same time produce a better quality of pipe as regards both glazing and burning than has heretofore been possible, and at the same time provide a kiln which shall be simple in its construction and thoroughly durable.

With the above objects in view the inven tion consists in the features of construction and combinations of parts, as'will be hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a horizontal section ofa kiln embodying my invention, and Fig. 2 is a detail vertical section.

Corresponding parts in both the figures are denoted by the same letters of reference.

Referring to the drawings, A represents the kiln, which, as shown, is substantially circular in form. The outer walls, B, of the kiln are preferably constructed of red brick, with an inner lining of fire-brick, and are provided at suitable intervals with fire arches or pockets a.

Orepresents an inner wall,which is arranged a short distance from the outer wall, 13, thereby leaving a fire-space, G, which is subdivided, so that there is a separate space for each 'firearch a. The walls which divide the space 0 also serve to support the walls B O.

The floor or bottom of the kiln may be constructed of fire-clay, brick, or other suitable material. v

D represents a well-hole which iscircular in form, and which is located in the center of the kiln and extends from the bottom thereof to the upper portion or floor, b, of the same.

This well -hole has communication near its lower end with a flue, E,which communicates with a stack. (Not shown.) The well-hole D is, as shown, divided into a series of compartments, (2, by means of walls 6, and the upper ends of said compartments are closed by means of brick,f, having concave sides,so that a practically open or perforated flooring for the wellhole is provided.

F represents a series of walls which extend from the inner wall, 0, and converge toward the well-hole and extend nearly to the latter, said walls being adapted to form the flooring for supporting the pipes to be glazed and burned. As the walls converge, and as it is essential that a space of about four inches should be left between each wall in order to accommodate the brick constituting the flooring, some of said walls are shorter than others and terminate a greater distance from the wellhole. may be readily laid and an even and uniform flooring provided. The brick employed for the flooring have concave sides similar: to those employed in the well-hole, so that a practically perforated flooring is provided.

The crown or dome G of the kiln is built on the outerwall, B, in any suitable manner, and extends about sixteen feet above the well-hole.

Entrances H are provided, and of which there may be any desired number; but when the pipes are in place for burning said entrances are bricked up.

In operation the fires are started in the several arches, and the heat ascends through the fire-spaces O to the flooring, over the wall 0, and reaches the highest point in the crown or dome and heats the latter. It then gradually distributes itself downward, performing its functions, and finally passes down through the center well-hole and out through the flue. this construction a great saving in fuel is effected and the pipe evenly and thoroughly burned.

Having thus described my invhtion, what I claim as new is- I 1. A briok-kilncomprising a circular outer wall, an inner wall, 0, connected with the outer wall at suitable intervals, a well-hole located in the center of the kiln, a series of Walls, F,

By this arrangement the fire-brick G extending inwardly from the wall 0 and conhole, and brick having concave faces and converging toward the well-hole, and a flooring meeting said walls, substantially as set forth. IO

connecting said walls,substantially asset forth. In testimony whereof I affix my signature in 2. A brick-kiln comprising a circular outer presence of two witnesses. 5 wall, an inner wall connected therewith at in GEORGE HOWES.
