SECIFICATION forming part of Letters Patent No. 720,971, dated February 17, 1908.

Application led May 14, 1902. Serial No. 10,355. (No mnf'lel To LLZZ whom it nur/y oon/cern:

Beit known that I, HATHEW E. ROTHBERG, a citizen of the United States, and a resident of Lebanon, in the county of Lebanon and State of Pennsylvania, have made a certain new and useful Invention in Coke-Ovens; and I declare the following to be a full, clear, and exact description of the saine, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to theaccompanyiugdrawings, and to letters of reference marked thereon, which form a part of this specification.

The invention relates to coke-ovens; and it consists in the novel construction` and com# binations of parts, as hereinafter set forth;

The object of the invention is to provide, in connection withhorizohtal open-end coke? ovens having a system of heating or combustion iiues between and underneath the cokingchambers, means for efficiently regulating and distributing the heat in thedifferent tlues,

thereby aording means for heating the different parts of the oven-wall at will, for'recovering the heat from the waste gases to the airsupply, and for utilizing the dead heatin the`- top of the ilues for heating the air before it e'n. ters into the combustion-iin es, whereby it is designed to secure great heat economy, strength of construction, and rapidity of coking action.

The nature of this improvement will be best understood in connection with the drawings illustrating the same, in which- Figure l is a longitudinal section throng a main system of heating and combustion lues, the section being taken on the line H H, Figs. 3 and 4. Fig. 2 is a longitudinal section taken on the line J J, Fig. 3. Fig. 3 shows vertical sectional views taken on the lines A A, B B, and C C, Fig. l, and also shows an end view of oven and line. Fig. 4c shows sections taken on the lines E E, F F, and G G,Fig. l, as well as a top view of the oven and flue. Figs. 5 and 6 are detail sectional views illustrating the valves f and adjacent parts.

The letter A' indicates a suitable foundation for the ovens B', this foundation containing a series of passages H', serving, respectively, as cooling fines for the ovens above them.

The ovens are built in adjacent pairs, as

.fines or passages B4. 'by short transverse deiectingpartitions c.

indicated, and the interval or wall in the strnctn re between the coking-chambers is hollow, its chamber portion or cavity being divided into two compartments byatransverse vertical. wall D. Each of these compartments is traversed by a vertical series of longitudinal horizontal combustion or heating ilues B3, formed by deiectingpartitions b, one above another, having, respectively, alternate'openings at their front and inner ends, such dues communicating at their ends and the series communicating below `with a series of short connected transverse horizontal fines G", the latter fines extending under the oven-chamber. The lower flue B3 communicates with ilues C by means of angular The lues C are formed To the uppermost of the series of iiues B3 extends a pipe H3 from the fuel-gas main G2, andthe heated Vgases pass through the ilues B3, B4, and C to the line C2 in the foundation, whereirom they pass out by means of a suitable stack; In the draft-flue C2 is located an air-pipe D2, in which air is heated by the waste gases passing to the stack, and this heated air is conveyed to the main air-pipe D3, which'communicates with hot-air iiues F3, formed .in4 the structure above the level of thetops of the ovens, byy means.V of a pipe F5, which is provided with a regulatingvalve E2. The pipe H3 from the fuel-gas main `is also provided with a regulating-valve G3. VThe flue F3 is provided with a longitudinal delecting-partition o, whereby the heated air is caused to traverse the structure back and forth to the passage to flue B3. Conneo tion can be made to the gas-main Gr2 by pas sage, pipe, or line E3, and the gas can be conveyed from pipe E3 to lines B3 by means of pipes E4, having regulating-dempers. Provision is also made for supplying the fines B3 with cold air by means of pipes ES'EB, having regnlating-dampers. The products of combnstiou can be made vto 'pass directly from each fine B3 to the next flue B5 without traversing the length of. the ine by means of short-circniting passages F4. The passages F4 are arranged in series under the pipe or flue H3 and in line with each other and are provided, respectively, with valves f, which can be opened or closed at will by removing plugs f in the Wall of the furnace to cut out one or more of the ilues B3, so that the heating may be changed from any part of the oven-Wall to any other part thereof at will. These plugs close openings in the Wall of the furnace, an opening being located adjacent to each such valve. By means of these combustion-ues and air-fines the oven-chambers are encompassed in su ch Wise that their heating can bev quickly accomplished and easily regulated to suit the Work. The flues F3 in the top of the structure serve to recover the dead heat and provide for its utilization in the air-supply.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Inadjacentopen-endcoking-ovens,aholloW longitudinal Wall separating the ovenchalnbers, longitudinal deflecting-partitions forming reverting combustion-fines in the cavity or chamber of said Wall, alternate partitions having openings therethrough forming short-circuiting passages connecting said lues, and provided With sliding valves, the oven-Wall having an opening adjacent to each such valve, and plugs for closing such openings, substantially as specified.

2. In adjacent coking-ovens, having the draft-flue provided With a hot-air pipe therein, a hollow longitudinal Wall separating the oven-chambers, longitudinal deecting partitions forming reverting combustion-fines in the cavity or chamber of said Wall, alternate partitions having openings therethrough forming short-circuiting passages connecting said fines and provided with sliding valves, the oven-wall having an opening adjacent to each such valve and plugs for closing said openings, said ovens having each a chamber thereunder provided with transverse partitions forming communicating flues leading to the draft-flue, and connecting With'said combustion-dues, said ovens having also air-fines above the oven chambers communicating With said combustion-fines, and With said hot- .air pipe, substantially as specified.

3; Inadjacentopen-endcoking-ovens,ahol low longitudinal Wall separating the ovenchambers, a series of longitudinal deflectingpartitions having respectively openings at alternate front and inner ends and forming a vertical series of horizontal reverting combustion-Ii ues .in the cavity or chamber of said wall, a fu el-pipe leading thereto, openings arranged in series in alternate partitions and in lineywith each other, and forming shortcircuiting passages Vconnecting said combustion-fines and provided respectively with sliding cut-out valves, whereby the action of the combustion-'lines is locally adjustable, substantially as specied.

In testimony whereof I affix my signature in presence of two Witnesses.
