To all whomvit may concern:

Be it known that I, FREDERICK PEITER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement' in Gas and Air `Controlling Means forv Coke-Ovens, of which the following is a full, clear, and exact description, reference being had to the accommethod or process' of coking coaljordinarily employed and I have alsodescribed my novel f method4 whereby these objections are overcbme, said. process v'or -method consisting broadly in supplying to the combustion flues at the beginning of the 'coking operation, va/n amount o'combustible gas and air sufiicient ste produce allofA the heat which can be safely and eiiicientl transmitted to the coal `mass to be cokedw ereby the preheating of the -eoal and ktlie;ini'tial coking operation is ateriallyexpedited, the supply of combussc ti lagases and`aif 'being gradually reduced l as the coking operation continues until at the end'fof the coking period the amount is about the same, or slightly less Ythan has been heretofore. used during the whole operation, thereby avoiding the overheatin of the brick work during the latter part o the coki-ng operation, Adecreasing the amount of cauliflower colte produced and producing a betterygrade of coke in ashorter space of The isothermal method oficoking coal r above described, and means for practising IOVreVerSin/g the flow of air and waste gases through the checkers, it being arranged, as "it is,"solelyfor the purposeofcontrolling Ythe uantity lof" gasndair being delivered 4to 4means that Ihave devised the present opvtype of mechanism which may be employed be done. The vfirst means suggesting itself would be to open the reversing valve a less amount each time, but as all of the ovens of a battery are controlled by one reversing mechanism and as some of them'would be nearlyv coked while others would be just .starting it would seem tounneeessarily complicate the equipment and it is with the View of producing a simple and highly efcient erative means.

It is the underlying principle of my in vention to control the temperature in the lues so as to produce the best quality of coke from available materials, and in the shortest time consistent therewith, regardless of whether this control shall be such :as to maintain vthe maximum temperaturefsafely l.attainable throughout the entire operation, `or such variation of this maximum 'asmay 7.5 be found most ,fdesirable. ,I Iii-the drawings forming a part of this specification, yFigure 1 is /a sectional view partly in elevation of one end of a coke oven to which my improved operative means is connected; Fig.- 2 is a detailview partly in. section of the gas valve and reversing mechanism; Figj is a plan view ofthe same; Fig. 4 is a sectional View partly in elevation on the line 'l1-4 ofFig. 3; Fig'. 5 is an enlarged'sectional view of the damper controlling the air duct; and 6 is a plan View of the same.

Fig. 7 is a diagrammatic plan viewof a for synchronously throttling the gas and air Supplyt Fig. 8 isa Vertical sectional View thereof on the line 8-8 of Fig. 7

Fig. 9 is an'end elevation of the structure illustrated in Fig. 7. i

In the general View `of Fig. 1 I have shown `but one end of an oven, and it will be understood that the opposite end of the oven iis equipped with means substantially the same 10o as that shown in Fig. 1.

In practice I prefer to use a separate valve or throttling device in the .air and gas pipes or ducts Abetweentlfie reversing valveand 'the oven burners and in carrying out thisv idea 105 I employ a shaft 10 mounted 'in a bracket 11 vat a point adjacent the gas valves, and upon this shaft is mounted the reversngjarm k12 adapted to alternately engage the stems 13 ofthe valves w14 controlling the inlet of gas 11o.

Thus We have the supply of gas and air progressively and gradually reduced after the iirst period of iiring. The push rod 30 can be pulled out by hand whenever it is desired to open the duct 29. The cam 25 is constructed upon the same lines as the cam 2l so that the throttling of the air will be in synchronism with the throttling ofthe fuel gas.

The apparatus herein shown and described is the preferred construction for accomplishing the operations herein set forth but 1t Wil be understood that certain changes and:Y modifications can be made Without depart-? ing from the broad principle of the invention and within the scope of the appended claims.
