BRICK-KILN SPECIFICATION forming part of Letters Patent No. 775,047, dated November 15, 1904.

Application tiled July v18, 1904.

Be it known that we, JOSEPH SONKA and ROBERT A. METZNER, citizens of the United States, residing at Seguin, in the county of Guadalupe and State of Texas, have invented certain new and useful lmprovementsin Brick- Kilns, of which the following is a specification.

This invention relates to brick-kilns, and particularly to a kiln equally as well adapted for making lime and Portland cement as for the manufacture of brick.

The object of the invention is to provide a kiln of such novel and peculiar construction and arrangement of parts that a more uniform and equal temperature of the Whole interior is effected and over or under heating is avoided.

A further object of the invention is to provide a smoke-consuming kiln of such special construction that no waste of heat is possible, and the heat is held at ahigh temperature throughout the kiln with the same or less amount of fuel comsurnption as any kiln known to applicants.

A still further object of the invention is to provide in a brick-kiln having fire-boxes at each end connected by independant iiues a retracted throat or passage for the furnace heat in the flues and to prevent draft from one fire-box to the other and radial draft passage or ducts from the flues through the walls of the latter. f

The object still further of the invention is to provide a kiln the top of which is flush with the ground-surface, affording a solid permanent floor or driveway, so that loading and unloading may be accomplished without the usual carting or other transportation of the brick to and from the kiln.

Other objects, advantages, and improved results are attainable in our improved kiln, as will be pointed out in the specification, and

Aset up in the claim to follow.

Brick-kilns, as far as known to us, have the upper half of fire-canal ricked up in arch form with inburned brick for each kiln charge, thereby requiring expert workman to prepare the kiln, and the brick of the arches which receive the heat direct are afterward worthless. Other kilns require a continued injury to the brick.

Serial No. 217,094. iNo model.)

heat for burning the brick; but according to our invention no such arch is required. The fire-arch being permanent and entirely below the Hoor-surface permits close approach of wagons or trucks. This smoke-consuming kiln permits the fire to be drawn at will without No special or expert workman are required, and greatsaving of brick and time and labor in handling the same is accomplished.

In the accompanying drawings, forming part of this application, Figurel is a perspective view of part of a kiln embodying our invention and partly broken away. Fig. 2 is asection on the line aj 90, Fig. l. F ig. 3 is a section on the line y y, Fig. 1. Fig. 4 is a section on the line a a, Fig. 3.

The same numeral references denote the saine parts throughout the several views of the drawings.

The kiln is composed of the usual number of fire-boxes and iiues and may be of any desired size or proportions, but for purposes of illustration only one pair of re-boxes and iues are shown. The fire-boxes lhave ordinary grates Q, doors 3, and iiues 4, leading from the said boxes and terminating in a contracted throat or passage 5, which prevents thelieat-currents from entering the iiues 4 too suddenly, retards the draft, and holds the heat-currents in the ues longer than if the flues were of the same size throughout or if the heat-currents were permitted to enter the flues in full volume from the fire-boxes. The iues as Well as the fire-boxes are separated by partition-walls 6, extending from one end to the other of the kiln, and with the arched top of the lu'es support a permanent kiln-licor 7 which is adapted to have the vehicles driven upon it in transporting brick to and from the kiln. The floor 7 is provided with heat-discharge apertures 8, between which the brick is stacked upon the ioor for drying and baking. Two sets or rows of the apertures 8 are connected with each of the iues 4 by radial ducts or channels 9, leading from the flues through the arched top of the fines, so as to distribute the heat-currents throughout the floor-surface. Theducts or channels may be of any desired number or inclination; but we Ioo prefer to arrange them at about an angle of forty-live degrees relative to each other and in rows extending through the ioor of the kiln. lt will be observed that the furnace is below the ground-surface, that the floor 7 is permanent, that the brick to be treated are not used to form any part of the kiln, so that the usual loss of brick is obviated, and that the kiln consumingsmoke and all particles of combustion will permit the fires to be drawn, as desired, during the process of cooking the brick without injury to the brick. l

1t is obvious that the iues are built in pairs lengthwise side by side, so that the walls thereofl support a continuous top surface or permanent floor, and that the furnaces have the usual smoke-stack or chimney and are provided with suitable regulating' devices.

lt will be seen that the heat will be distributed equally throughout the kiln, that the brick are cooked or burned from bottom to top with perfect uniformity, that the arrangement of the heat and draft passages are such as to reduce loss of heat, and that the ducts terminating in a flat level surface will admit of improved facilities for handling the material.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is@ i In a brick-kiln, the combination, with the walls forming separate flues each of which terminates in a contracted passage central of the flues, and the permanent floor forming a driveway Hush with the ground-surface and having adjacent double rows of apertures arranged in pairs central of the said walls, of the ducts or channels inclined upwardly and outwardly from each other and connecting the top of the said iiues with said apertures.

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