Application lled July 3,1906. Serial No. 324.591.

To all 'whom it 'may concern:

Be it known that I, FREDERICK ALBIN WEIGEL, a citizen of the United States, residing at Johnetta, in the county of Armstrong and State4 of Pennsylvania, have invented certain new and useful Improvements in Burning-Kilns; and I do 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a new and useful improvement in down draft kilns for the burning of brick, sewer pipe, or any article formed from ear-thor clay.

The primary object of my invention is the construction of a kiln in which a regular heat may be obtained throughout the entire burning chamber, thus being able to burn the contents to a uniform hardness and by means of the arrangement of Hues and draft passages being able to deflect the heat to any desired point.

Another feature of my invention is the method of drawing off the heat from the burning chamber and effecting a gradual cooling off of the contents, also thel convenient and practical method of cleaning the kiln alter each burning process.

In the accompanying drawings, in three sheets, forming a part of this specification, I have shown several detailed views of my invention, Figure l being a longitudinal section on line 1 1 of Fig. 3. Fig. 2, Sheet 2, is a plan view showing draft flues leading to stack. Fig. 3, Sheet 3, is a cross sectional view on line 3 3 of Fig. l. Fig. 4, Sheet l, is a plan view of a section of the checker Work flooring before the nal layer of brick is put on. Fig. 5, Sheet 3, is a similar view showing one-half complete with the final layer of bricks. Fig. G, Sheet 2, is a modified form for connecting the circular draft passage with the stack.

Throughout the drawings the numeral l indicates the structural work of what is familiar-ly known as a bee hive oven, or burning kiln. At stated intervals around the oven are arranged heating furnaces 2 and at one side, any convenient distance from the oven, is a draft stack 3.

Extending from side to side of the oven is an arched passage-way 4 one end built abruptly against the side of the oven and the opposite end communicating with an air-well, or man-hole 5. Communicating with this passage-way 4, which it enters at right angles midway between the ends thereof, is a vflue 6 leading to the draft stack 3, and located in this flue is a damper 6. Through the top of the arched passage-way 4 at stated intervals are arranged a plurality of openings 7 7.

nilt at right angles with the arched passage-way 4 between the openings 7 7 and parallel with the flue 6, are the solid brick walls 8 8, Fig. 3, the ends thereof ending a short distance from the wall oi the oven, shown Iby dotted line in Fig. 2, leaving a circular passageway 9. v

The floor of each air space l0 formed between these 1 walls 8, is inclined from the circular passage-way 9 to where it communicates with the openings 7 7 formed in the arched passage-way 4, allvexcept the central passage-way above the draft flue 6, which has a flat floor. The object of having these sloping floors is to facilitate the cleaning of the oven, as the scale from the burning brick and sand used in setting layers of brick will sift through the floor into the passage-ways l() and can readily be drawn into the arched passage-way 4 and from there hauled away.

The walls 8 8, before referred to, are built to a predetermined and uniform height and upon these walls, and at right angles therewith, are courses of brick ll-ll; leaving air spaces between each course. Upon these courses of brick, and running at right angles therewith, is the floor l2, which consists of a series of brick v laid in strips; leaving a space between each two strips,

A dividing wall 13 separates the ends of the circular passage-way 9, and each end of said passage-way communicates with an opening 14 into the flue 6. Located near each end of each passage-way 9 are the dampers 15-15. As a modified form of construction, the ends of this circular passage-way 9 may be led directly into the stack, shown in Fig. 6.

Arranged in the walls of the oven at each side of the furnace 2, and adjacent thereto, are air passages 1G and 17 to prevent buckling or bulging of the walls of the oven; the passage-way 17 communicating with the interior of the oven.

One or more doors 18 are arranged through the wall of the oven for filling and removing brick.

In the operation of my improved burning kiln, the green brick, or other clay material, is hauled into the oven through the door 18 and piled upon the iioor l2 in a well known manner. rl`he heat from the furnaces 2 entering the oven is drawn down through this green material and upon reaching the floor l2 it escapes through the space between the strips of brick, and is then deflected to the right and left, passes down between the supporting columns Il ll, thence into the passage-way l0 between the walls 8 8, and is then drawn into the arched passage-way 4 through the openings 7 7 and from there into the flues G; where it escapes out of the stack 3. It being a well known fact that atmospheric conditions have a great deal to do with the burning of brick and that often times one side of the kiln will burn faster than the other. I have provided a means whereby a portion of the heat in the kiln can be drawn to either side and thus by equalizing the same, cause a more even burning of the green material. This particular feature that I have providedv consists in the circular passage-way 9, which acts as an auxiliary flue in accomplishing the above result. As an example we will suppose that owing to certain atmospheric conditions one side of the kiln is discovered to be hotter than the other, all that is required is for the man in charge to raise the damper 15 in the Aend of the passage-way 9 at whatever side of the kiln he desires to draw the heat. A portion of the heat, which ordinarily will rush toward the center of the kiln where the draft is strongest, will thus be deflected to whatever side the operator desires and where the burning has been slowest heretofore. In this manner the distribution of heat in the kiln can be equalized to overcome any change in the atmospheric conditions.

In the cooling off process necessary before removing the bricks from the kiln, the ports 19 formed through the roof of the kiln are opened, thus admitting cold air to the burning chamber. Cold air will also be admitted through the passage-ways 17 formed in the wall of the kiln, and as an additional means for furnishing cold air to assist in carrying off the heated atmosphere in the kiln, have provided the air well 5 which communicates with the passage-way 4. In this manner a sufficient volume of cold air can be drawn into the kiln to insure the rapid and efficient cooling off of the burned material. The air well 5 also acts as a man-hole in obtaining access to the passage way 4 when it becomes necessary to clean the kiln of the scale and sand, but is kept covered during the burning process.

An additional air well can be provided at the opposite end of the passage way 4 in case the conditions and nature of the construction would Warrent the same being done.

Other minor changes in the detailed form of construction may also be made Without in any manner changing or departing from my original idea.

Having therefore fully described and shown my'invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In a device of the character described, a suitable burning kiln; a covered passage-way extending from side to side of the kiln; means, communicating with said passage-way, for drawing cold air into the kiln and for cleaning said kiln; a draft ilue intersecting said passageway and extending to a draft stack; a damper in said flue;
