SPECIFICATION forming part of Letters Patent No. 288,874, dated November 20, 1883.

Application filed September 26, 1883. (No modelfl' Patented in France September 24, 1881, No. 145,007; in England January 13, 18S-2, No. IE6; in Austria-Hungary January 16, 1382, No. 2,996 and No. 12,981 in Spain January 24, 1882, No. 2,652,- in Denmark January 30, 1852, No. 335 3 in Norway February 2, 1882, and in Sweden February 14, 1882.

To all' whom t 11mg/ concern.-

Be it known that l, Gnonens SEIBEL, of Cransac, France, have invented a new and useful Improvement inCoke-Furnaces, (for which l have obtained Patent in France on September 24, 1881, No. 145,007 5 in Austria-Hungary No. 2,996, and No. 12, 981, on January 16, 1882; in England, No. 186, on January 13, 1882; in Spain, No. 2,652, on January 24, 1882; in Denniark, No. 335, on January 30, 1882 5 in Sweden on February 14, 1882, and in Norway on February 2, 1882,) of which the following is a specifica-tion.

My invention relates to the manufacture of coke from coal, especially from bituminous coal, and is based on the fact, observed by me, that the hydrocarbon gases produced by the distillation of coal, and passing at a high temperature through a mass of coal which is being converted into coke, yield a portion of their carbon to the spongy material through which they are passing, and that the quantity of carbon thus given off increases with the thickness of the coal stratum through which the said gases are filtered.

My invention consists of a peculiar combination of ues and tuyeres in a coke-oven, which dispenses entirely with a grate, land is heated by the gas arising from the distillation of the coal, and will be fully set forth in the description below,aud pointed out in the claims.

In the accompanying drawings, which represent a series of furnaces embodying my invention, Figure 1 is a vertical section across the cokechanibers, ta-ken at different parts of their length, the planes of section being indicated in Fig. 3, and designated with l Il lll IV V VI. Fig. 2 is a longitudinal section of a coke-chamber, taken along the plane H H of Fig. 1. Fig. 3 is a vert-ical section along the plane L L of Fig. 1; Fig. 4., ahorizontal section of a furnace along the plane M M of Fig. 3; Fig. 5, a section along the plane N N', and

Fig. 6 a sect-ion along line It Il. Fig. 7 is a,`

front view of a furnace, the line x y indicating the sole of the coke-chambers.

The coke-chamber A, covered by a vault, is about 1.98 meters high, 0.700 meters wide, and six meters long. 7`With these dimensions the quantity of coal in one chamber is about live thousand kilograms. It should be charged with coal to a height of at least 1.700 meters.

'The partitions which separate the furnaces are provided with three horizontal flues, B, B', and B2, communicating with two fines, C, under the sole ofthe furnace, leading through a vertical flue, D, to a large collecting-gallery, E. This gallery passes along the front of the furnaces at a lower level than the sole, and carries the gases of combustion from all furnaces to a chimney. Before arriving there the hot gases may be utilized for heating boilers.'

In order to obtain the desired result-that is to say, the deposit of a part of the carbon contained in the gaseous products of distilla tion in the pores of the coke which is in course of formationit is necessary to commence the carbonization of coal at the top. For this purpose gas is introduced at one end of the upper ilues, B B, through suitable tuyeres,F F, and ignited, the air necessary to aid combustion being admitted through the center of said tuyeres and controlled as to amount by suitable dampers. (See Fig. 3.)

By this construction the grate used in other coke-furnaces heated by gas is dispensed with. The gases of combustion formed in the upper ue pass downward through the central and lower iiue to the sole of the furnace, and from there to the chimney, heating during their passage the walls and base of the furnace.

After the chamber A has been charged with coal, its walls are nearly cold; but the gas ignited in the upper ilue heats rapidly the top of the furnace, where the distillation of coal begins. The tempera-ture soon rises also in the lower part of the furnace and causes the distillation to extend to the whole mass of coal. The gases formed in the lower part give oft' a part of their carbon to the material in the upper part, whereby the production of coke in this furnace is considerably increased. The gas produced in the chamber A is drawn out at P by an aspirator, which presses the gas directly into the furnace after it has been puriiied from tar and ammoniacal water. From the delivery-pipe l lead a branch pipe to a gasholder. As soon as an abundance of gas is produced in the furnace the pipe leading to the latter is closed' for some time and the gas I conducted to the gas-holder, from where it may which case a greater supply of gas is required for rapidly heating the furnace.

Instead of three superposed flu'es, as shown j in the drawings, two or more than three may 'be used.

What I claim is- I. In a coke-oven, the combination of the iiues B, having` the tuyeres F,With the flues B B2, provided with the supplementary tuyeres which divides said flues B B2, the partition deiiecting the ame equally into each to rapidly heat the lower part of the oven, as set forth.

2. In a coke-oven, the combination of the iiues B, having the tuyeres F, and the flues B B, provided with the supplementary tuyeres G, entering directlyopposite to the partition which divides them, with the iiues C D and the gas-reservoir E, as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
