To all whom t may concern: hereinafter full described and pointed out Be it known that I, EUGNE LEcocQ, a in the appendedY claims. sub'ect of the King of Belgium, residing The annexed drawings show by way of at russels, in thc Kingdom of Bel ium, example a coke oven constructed according have invented certain new and usefu Im? to my invention.

It is evident that vthe eration assuring the maximum economy and number of regenerators provlded in a sircilgle 105 diminishing the. heat lost by radiation and group and for each oven can be varied. e conductii. two ducts 9 of two groups of regenerators l ith these objectsin view my invention coperating with a single furnace, ducts essentially consists in the special arrangewhich are arranged in the same axisas that ments and combinations of parts as will be of the corresponding combustion chamber 2, 110

are in communication with the under conduit 15 arranged parallel in the Hoor of the oven and extending the length thereof. Two of these adjacent conduits are connected (as shown in Fig. 4:) to the ducts 9 connected to the regenerators of the same group, e., situated at the same side of` the gallery and also two adjacent conduits 15 are conneoted to the ducts 9 in connnunication with the group of regenerators situated on the other side. ot' the gallery (l. The conduits '15 as required distribute the. air to or collect the burnt gases from the chambers 2 by the ducts 16 connected to the combustion compartments 1T in the chambers 2. The gas is distributed to each chamber by a series of ducts 1.8 connected to a gas pipe v1S).

The working of the Jfurnace can be readily understood. By way of example the passage of the air and of the. burnt ga.C s is indi cated in. the arrangement: dest ibed. The air coming from the gallery l. li lgs. 1 and il, and having passed through the reversing apparatus 14, Fig. 3. puisses into the` collert4 ing flue` 13. Figs. l. and Il in the direction indicated bv the arrows du. .Vig 3, and is distril'luied into the. iarious regeuerators 5, Fig. l. .forsrwslmnding to the heating chain bers 17, Fig. 1. olI the ovens; it is heated up in the three regenerators Il. Il. arranged in series and then passes to the corresponding duct 9 and to one of the two underneath conduits l5. Figs. *2 and l. from which 'it is distributed by the ducts 16 to the various compartments 1T ot" the combustion chambers. The heated air combines in the conv partments 1T with the. gas distributed by the pipes 1S. The 'nurnt passes down the vertical compartments Q1, Fig. l, into the neighboring conduits 'l5 underneath the chamber by the corresponding duct 1G and thence to the regenerators 3, 4, 5 of the seo ond group by the course indicated by the arrows Figs. 1 and 4. After passing through these rcgenerators the gas entersv the second collecting Hue 13, Figs. 1 and 3, and. through the reversing apparatus 14: to the chimney. The passage of the air and gases is then reversed, the air passing in the op posite direction through all the ducts and compartments previously traversed by the burnt gases.

On examining the drawings it is seen that owing to the arrangement of the regeneretors all the structure of the oven is conveniently supported by the moreover owing to the arran ment of the regenerators in the axis O t e combustion chambers the height of the structure is oonsiderably reduced as the lateral space neu-.ssary for the underneath conduits 15 is obtained without adding to the hei ht of this part of the structure. Thel air an the burnt gases canbe easil regulated at will in each combustion cham r as two adjacent undermasonry and neath conduits are used for each oven, in which the air andthe gases move in the same direction (see the direction of arrows Q3 Fig. 4) thus allowing'the possibility otf creating an equal pressure for each compartment in the chamber and so regulating the quantity of air passing into each vertical compartment of the combustion cham-ber.

Finally the described construction with the regenerators arranged in series considerably decreases the heat lost by radiation and conduction.

It is evident that the invention is not liniited hy the construction described and shown and that the details can he varied. Thus for example the number of regcncrators in each group and for cach oven can bemore or less than three and moreover they may be arranged in parallel instead of in series as described. A

lt will he observed that in sulldividing each transverse regenerate!" or group of two transverse. regcneratois cooperating with a single oven into several separate regenerators the axes of which are vertical and which are formed hy rhamliers of masonry forming towers of ma nry the whole struff ture is extremely sola and allows of ay construction much lighter th an hitherto.

Having thus described my invention, what l claim is:

In a regenerator coke oven. the combination with a plurality of ovens and their combustion chambers having their major axes horizontally disposed, of a support ing structure for said ovens and combos tion chambers, forming a plurality of chambers disposed directly beneath said ovens and having their major axes vertically disposed. and a regeneraior formed in each of said last named chambers.
