cokn-ov 111 citizen of the United States, and resident of New Rochelle, in the county ofWes chester and State of New York, have invented certain new and v useful llmprove ments in Coke-Uven-Wall Constructions,- of whichthe following is a specification.

My present invention relates to coke ovens of the well known and widely used type in which each oven battery comprises a plurality of horizontally elongated coke oven chambers, each adjacent pair of which are separated by a heating wall formed with flue passages through which the heating gases flow. Tn this type of even as hereto-.

fore constructed .it has been found practically impossible to prevent leakage between the oven chambers, and the flue spaces in the end portions of the adjacent heating walls The brick work forming the ends of the heating wall is subjected to temperatures which average lower, and fluctuate more than the temperatures to which the bodies of the heating walls are subjected, and the resultant relative expansion and contraction of the bricks in the end portions: "of the heating walls tends to open the brick work joints. The mechanical stresses to which the brick work at the ends of the heating wall is subjected in discharging the ovens and in removing and replacing the oven doors also tends to loosen and open the joints. The gas leakage thuscaused is objectionable as it involves a wastage of gas and by-products and interferes with the desired uniformity in oven heating.

The general object of the present invention is to provide a special construction at the ends of the heating walls which will eliminate or substantially minimize leakage between the oven chambers and the flue spaces in the oven wall. lln carrying out my invention ll employ metallic flashplates fill or armor and so shape this metallic armor and the adjacent brick work that the armor clamps the bricks forming the end and adjacent side portions of each heating wall together, and thereby prevents the corresponding joints from opening under the normal operating conditions to which they are subjected. The armor employed may also serve the purpose for which armor has heretofore been placed on the ends of the oven heating walls; namely of protecting specification of Letters Patent.

the brickwork from water and mechanical in uriesand to form doorway frames for the oven doors.

The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part ofthis specification. For a better understanding of the invention, however, and the advantages possessed by it, reference should be had to the accompanyin drawings and descriptive matter in which have illustrated and described preferred embodiments of my invention,

@f the drawings:

Figural is an elevation of a portion of a coke oven battery;

Fig. 2 is a section taken on the line 9 of Fig. 1 but on a smaller scale;

Fig. 3 is a partial sectional plan on the line 33 of lEig. 1; and

Figs. 4:, 5, 6 and 7 are sectional plans illustrating modified forms of construction.

Tn the drawings and referring first to Figs. 1, 2 and 3, T have shown a portion of a coke oven structure which, in its general form, is of the type now in most common use in large capacity by-products coke ovens. This coke oven structure is provided with horizontally elongated coking chambers A separated by heating walls in which are formed vertical heating flues B. The sides of the heating walls are formed by the socalled liner bricks C and C and the adjacent fines are separatedby walls formed b%socalled bottle bricks The end flue in each heating wall has its outer wall formed by bricks E. The bricks C and D may be of the usual form, but the bricks C have their outer edges bevcledat C for engagement by the correspondingly beveled shoulders E of the bricks 1E, and the latter are formed with tongue portione E which extend between and are engaged by the flat 1nner sides of the adjacent bricks C". The shoulders C of the bricks C at the two sides of each heating wall end are oppositely beveled so that the shoulders E of the bricks E hold the bricks C engaged by them against the tongue portion E With this arrangement a relatively long joint I is' too I ing action of the shoulder E of the bricks E exerted against the beveled surfaces C of the bricks C. To make this clamping action permanently effective, and to -mini mize the tendency of the brick shoulders E faces of the bricks E and the sides of the shoulders E of the bricks E forming each end heating wall are incased in a trough Yshaped metallic fiashplate or reinforcing member F ordinarily made of castv iron.

against movement away from the oven structure by the usual oven buckstays G. The flashplates form the sides of the doorways at the ends ofthe oven chambers,'and are shaped to correspond to the type of door employed. A

' In the particular door and doorway construction illustrated in Figsl, 2 and 3, the doors H employed are shaped to move freely between the edges of the flashplates, and the metallic frame H of each door and the adjacent flashplate edges are so relatively doorway, and the doors are secured in place by locking bars L engaging brackets Q carshaped as to provide a narrow trough shaped groove J in which the usual joint luting material may be placed. Preferably the doorways are provided with metallic sills at their bottoms, and metallic lintels K connect the flashplates at the tops of the iiedJoy the buckstays G.- The special door construction illustrated and the shaping. of the flashplates to conform to this door construction, although novel with me, is not claimed herein, but. is claimed" in my copending application, Serial No; 437,6 l7.

In the modification shown in Fig. 4 each I of the bricks E of the construction shown inF'igs. -1, 2 and 3, "is replaced by two bricksEA and EB each of which is formed- -with one shoulder E, and a portion of the tongue E In Fig. 4 I have illustrated a GA externallv modified form'of door HA, and 'a flashplate shaped to provide a shoulder Gr againstwhich a ortion of the metallic frameof the door' A abuts, at the inner or bottom edge of. the trough provided to 7 rece ve the luting material. f Y

- In the. modification shown in Fig. 5, the

' bricks E'Oforming the outer walls of the end fiues B are rectangular blocks which fit between the liner bricks G, and the latter are-recessed at theirouter corners as indicated at C to receive the sides of the trough shaped flashplates GB which, in this construction,- not only abut directly against the recessed sides of the bricks C but also against the outer edges of those bricks.

The construction illustrated in Fig. 6. differs from that shown'in Fig. 5 in that the blocks project out beyond the outer above.

I wall bricks between them.

edges of the bricks C and small rectangular bricks ED- are interposed between the ends of the bricks C and the flashplates GG,

-which are shaped to fit against the outer .struction, howeveiythe outer faces or edges Ihe flashplates F are engaged and held,

of the bricks C and the shoulders E are beveled, not as shown in Fig. 3 but 1n the opposite direction, and the bricks C are rectly sealed by the flashplates GD. The I differentiated-from the forms shown in Figs.

3, 4, 5 and 6 are claimed in my co-pending application, Serial N0.437,64:7, referredto In the normal contemplatedmode of constructing a coke oven comprlsing the improvements disclosed herein, the flashplates are set in place before the heating walls are built, and the bricks at the ends of the heating' walls are laid against the flashplates thus insuring the proper initial relative arrangement of bricks and flashplates. When thereafter theovens are heated up and the parts contract and expand with the varying,

temperatures to Which'they are subjected in operation, the buckstays at the opposite ends of each heating wall which are connected by .the' usual tie rods (not shown) hold the flashplates at all times snugly against the ends of the'heating wall. In consequence of this and the special shaping and arrangement of the flashplates and adjacent brick work, the flashplates at all times positivel hold the liner bricks at the sides of cum endflue B against the portion of the end leakage between the end flues and the oven chambers since the leakage paths are comparatively long, and with the bricks at the opposite sides of theq'oints held firmly together the joints, in .case leakage develops, are quickly rescaled by dust or residue carendwall-bricks. This practically eliminates raeaeea ried into the joints by the gases leaking therethrough.

While in accordance with the provisions of the statutes 1 have illustrated and described the best form of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed without departing from the spirit of my invention as set forth in the appended claims, and that certain features of my invention may sometimes be used to advantage without a corresponding use of other features.

Having now described my invention what claim as new and desire to secure by Letters Patent, is: v

1. In a coke oven structure comprising coking chambers and interposed hollow heating walls, the improvement which consists of brickwork forming the outer end.

and the side walls of the flue spaces ,in the ends of the heating walls and metallic armor for the ends of the heatingwalls', said armor and brickwork being so relatively arranged and disposed that the armor positively holds the side wall bricks against spreading.

2. In a coke oven structure comprising coking chambers and interposed heating walls formed with vertical heating flues, the combination with bricks forming the side walls of each heating wall end flue,: of bricks interposed between the side wall bricks of each end flue to form the outer end wall oi? the flue, and metallic armor for the ends of the heating walls arranged to positively hold the sidewall bricks against the interposed bricks.

3. In a coke oven structure comprising coking chambers and interposed flue heating walls, the improved heating wall end construction "comprising spaced apart liner bricks having their outer ends oppositely beveled and end wall bricks comprising tongue portions interposed between the liner bricks and laterally projecting shoulders undercutxto fit against the beveled ends of the liner bricks and a trough shaped metallic member incasing the outer faces and the side edges of the shoulders of the end wall bricks.
