Application filed July 26, 1916. Serial No. 111,521.

To all whom z' may concern:

Be it known that I, PIERRE PLANTINGA, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Coke-Ovens, of which the following is a speciiication, vthe principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to coke ovens and particularly to coke ovens having side walls which diverge from the charging toward the discharging end, certain features thereof, however, being particularly adaptable to and advantageous in connection with coke ovens in which the side walls of the coking chambers diverge and in which such chambers incline downwardly from the charging toward the discharging end.

The object of the invention is to provide a coke oven which will be economical of construction and etticient in its operation.

The annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of Various mechanical forms in which the principle of the invention may be employed.

In said annexed drawings z- Figure 1 represents a section of a frag-v mentary portion of a coke oven installation embodying my invention, taken upon the planes indicated by lines I-I in Fig. 5, the greater portion of such planes being parallel with the tioor of the retort.

Fig. 2 represents a fragmentary transverse vertical section taken upon the plane indicated by the line II-II in Fig. 1 and viewed in the direction indicated by the arrows.

Fig. 3 represents a fragmentary longitudinal vertical section taken upon the plane indicated by the line Ill-1H in Fig. 1 and viewed in the direction indicated by the arrows.

Fig. et represents a transverse vertical section taken upon the plane indicated by the line V--IV in Fig. l and viewed in the direction indicated by the arrows.

Fig. 5 represents a transverse vertical section taken upon the plane indicated by the line V-V in Fig. 1 and viewed in the direction indicated by the arrows.

Fig. 6 represents a longitudinal vertical Section taken upon the plane indicated by the line VI-Vll in Figs. l and 5 and viewed in the direction indicated by the arrows.

Fig. 7 represents a longitudinal vertical section taken upon the plane indicated by the line VII-Vil in Fig. 2 and viewed in the direction indicated by the arrows.

The illustrated embodiment of my invention comprises an outer casing or housing 1 of the required dimensions, such dimensions depending upon the number and size of the @cking-chambers, as will be readily understood. Formed within the casing is a plurality of coking-chambers 2 whose sides, top and bottom are formed of suitable tile la abutting and joined wit-h each other, the joints formed by the tile elements ruiming in the general direction, that is parallel with the direction, of inclination of the chambers, and at right angles thereto, as shown in Figs. 4 and The upper end of each such coking-chamber is closed by means of a suitable removable closure 3 and communieating with such upper or rear end is a charging duct 4 closed by a suitable closure 5, as shown in Fig. 4;. Each coking-chamber is furthermore provided with a vertical gas take-oil flue 6 connected with a suitable pipe 7 for conducting the gases formed to the desired point.

The lower or front. end of each chamber is closed by means of a suitable removable closure 8, as shown in Figs. 1 and el.

The coal is charged through the charging duct 4. into the chamber and when the' coking operation is complcteil, the closures 3 and 8 are removed and the contents removed by pushing same from the rear out through the front end, as will he readily understood.

Adjacent. to each side ofeach cokingchamber is a set of parallel combustionchambers 9, these chambers also zinclining and having a direction of inclination parallel with that of the general direction of inclination of the cokinchambers as shown in Fig. 5. The upper or rear ends of each of the combustion-chambers comprising a given set, communicate with a vertical iiue 10 which in turn communicates with a horizontal flue 11 which leads to the stack (not shown). This flue receives and takes off the gases of combustion formed in the combustion-chamber. Opposite the upper end of each con'dmstion'chaiaber 9 a shelf l2 and side ledges 13, this shelf and ledges supporting a valve 14 which may be reached through an opening 15 normally closed by means of a removable closure 16, F ig. 5. The efflux of the gases of combustion through the lues 10 and 11 are capable of regulation by means of these valves, as will be readily understood.`

A. longitudinal air duct 17, Figs. 2, l and 5, is provided and communicates by means of horizontal passages 18 with a vertical duct 19. The air duct 17 is usually connected with a recuperator (not shown) such as is ordinarily provided in this class of devices, as will be readily understood. One such duct 19 is located between the front ends of each two adjacent sets of combustion-chambers, as shown in Fig. 1, and communicates with a plurality of air inlets 20, one of which is located adjacent to the lower end of each combustion-chamber, as shown in Fig. 5. These air ducts are controlled by valves 21, Fig. 2, which are located in passages 22 normally closed by closures 23 and through which they may be reached for adv justment. The influx of air at these points is hence capable of regulation. An additional air inlet 24 isprovided, as shown in Figs. 2 and 5, and also controlled by means of a valve 25 located in a passage 26 and closed by a closure 27. This last-named air inlet communicates directlyT with the horizontal passage 18, as shown.

Opposite the lower ends of each set oi combustion-chambers is a vertical flue 28 whose lower end communicates with a gas duct 29 which itself is connected with a suit-- able source of fuel gas (not shown).

rlhe device as above-described operates as follows:

The gas from the duct 29 flows upwardly into the duct 28 and becomes mixed with air from the inlet 24. Additional air from the inlets 20 is mixed with the mixture of air and gas first formed, and is then burned. These gases of combustion pass up through the combustion-chambers 9 and llow out through the lues 10 and 11. During such passage they heat the sides of the cokingchambers and effect the coking operation.

By arranging the apparatus, however, as described, that is, by permitting the initial combustion to take place at the lower or wider end of the coking-chamber, the maximum temperature will be applied at this Wider end where it is required, a larger mass of coke being located at this point and hence a higher ,degree of temperaturebeing required. As the gases of combustion travel through the chambers or heating flues 9, and part with their heat, they are required, as they progress, to heat a volume of coal which grows smaller in the direction of travel of such gases, so that the mass of coal decreases as the gases become cooler. By suitable regulation ot the valves resaca? the combustion-chambers lie in planes which intersect one another, the arrangement therefore being such that the adjacent joints break with each other. By means of this arrangement the cracking of these adjacent walls is minimized, as will be understood.

The side walls of all the coking-chambers diverge in the same direction, as will be seen in Fig. 1. Fart of the partition walls 30, as is shown in said figure, are rectangular in horizontal section, but certain 'of these walls, as for instance wall 31, are built so that their sides will diverge in the direction opposite from that of the direction of divergence of the coking-chambers, as shown.. By providing such a wedge-shaped partition wall at suitable intervals, the rectilinear form of the entire installation may be preserved.

In the above-described manner, therefore, l obtain a coke oven installation which may contain any required number of cokingchambers, provide means whereby these coking-chambers and hence their contents are uniformly heated, and reduce cracking of the adjacent walls which expansion and contraction tends to produce, to a minimum. l am also, by means of the above-described 105 construction, enabled to incorporate in the installation, the diverging or wedge-shaped form of coking chamber, but still preserve the general rectilinear form of the entire installation.

Having fully described my invention, what l claim and desire to secure by Letters Patenty is 1. lin a coke oven,l the combination of an inclined coking chamber; a set of parallel 115 combustion chambers arranged one above the other and adjacent to one side of said coking chamber; avertical duct adjacent to the lower ends of the combustion chambers of said set; a gas suppl for supply- 120 ing fuel gas to said duct; a p urality of air 1n e ts, one such inlet being locatd adjacent combustion chambers and adapted to control ihe exit of gases through said upper vertical uct.
