The general object of to provide an improved coke oven door for useI in removably closing the ends of horizontally elongated coke ovens.

More specifically, the isto provide an improve 13 Claims.

the present invention is object of the invention d coke oven door of the known so-called self sealing type comprising a rigid metallic outer door element or frame section, an inner refractory plugsection of the door acterized by the n ovel of the end of the corremanner in which the bricks or refractory blocks forming the body yportion refractory plug section of the door, and the means for directly supporting and holding said 4bricks or blocks in place, are formed and ar- .1 ranged. In a preferred vention the refractory form of the present inblock material extends by a metal post as to form a self .sustaining unit, which is detachably connected to the metallic l, outer portion. of the door by metallic parts engaging the top and bottom of said post.

pectively, of the door Figure 9 is a perspective View of the door brick supporting parts of the Figure 6, and,

door portion shown in Figure 10 is a perspective view'oi one of the parts shown in Figure 9, as seen from a different viewpoint. y

The coke oven illustrated in the drawings is one comprising horizontally elongated coking chambers A and heating Walls B arranged side 5 by side in a row in which the coking chambers alternate with the heating walls. The coke oven masonry is reinforced and supported at the sides of the battery by a metallic armor, shown as com prising a flash plate G and a corresponding vertical buckstay D by which the flash plate is held in place. Atl each end of each coking chamber end is a door frame member E. The latter preferably, and as shown, is in the formr of a one-piece casting extending l5 around the door opening, and of substantial horif. zontal depth measured in the direction of the length of the heating Walls and coking chambers, the heating'walls being recessed at their vertical corners as indicated at B to receive inner portions of the corresponding door frame members E, each of which extend intothe oven structure and provides a metallic lining for the corresponding coking chamber end.

As shown, each door frame member Eis anchored in place by adjustable clamping connections between its sides and the adjacent buckstay members D. The clamping connections shown comprise parts d welded to the buckstay members, and clamping levers F and bolts G. Each clamping lever F engages the corresponding door frame member E at one end, and at its opposite end engages a corresponding part d andA is subjected to a` suitable clamping force by means of the corresponding clamping bolt G, which acts between the lever F and the" corresponding part d. In the construction shown, each door frame `member E includes adjustable flange portions e at its sides which abut against adjacent edge portions of the adjacent flash plates G.

In the form illustrated in the drawings, each door comprises a rigid outer metallic frame section, which in the particular form shown, includes vertical channel bar members I-I at the opposite sides of the door, top, bottom,l and one 45 or more intermediate cross frame members H', and other cross frame members I-I2 and H3, the cross frame members being welded at their ends to the side frame members H. The cross frame members H2 provide anchorages for the pivot 50 at each heating wall end, 10

lock the door to and unlock it from said door frame member. The cross frame member H3 is provided for engagement by an operating part of the usual door handling machine (not shown) employed to move the door into and out of its normal closed position in which the door extends into the doorway.

The intermediate exible plate section or element of the door in the form shown in Figures 1-3 comprises a one-piece part K of metal plate, which may be a quarter of an inch or so thick and includes a substantially flat body portion, which in the closed position of the door extends entirely across the door opening, and an integral inturned rim or liange portion K' at the margin of said body portion, which then engages the sealing surface E formed on the corresponding door frame member E.

The plate member K is connected to and suspended from the outer frame section of the door at or adjacent the top of the door by means shown as including a horizontal shaft L, passing through and supported at its ends by heavy plate or lug parts welded to the head portions of the channel bars H forming the side members of the rigid outer door frame section. The shaft L also passes through openings in brackets or lugs K6 secured to the upper portion of the plate K, said openings preferably being horizontally elongated as shown. The lugs K are welded or otherwise secured to a horizontal channel bar K7 secured to the plate K by bolts K8 which pass through the base portion of the channel bar K7 and through the plate K and through a flange M of a casting or other heavy metal part M thereby secured to the plate K. The member M extends into the oven chamber when the door is in its closed position shown in Figure 2.

In order to distort the sealing member K to ensure proper engagement of its sealing edge K with the sealing surface E of the door frame member E, a plurality of screws N are mounted at suitably distributed points along the margin of the rigid outer frame section of the door. The head of each screw N engages a recess in a corresponding small pad or reinforcing part O welded to the outer side of the member K.

The intermediate sealing member or section and the clamping means employed to distort said sealing member form the subject matter of my British patent application No. 115 /36 from which the present invention is divided.

The bricks or refractory blocks Q, Q' and Q2 constituting the body portion of the plug section of the door are stacked up on a rigid supporting member R secured to the inner side of the body portion of the member K adjacent the lower end of the latter. As shown, the member R comprises a horizontal portion R on which the brick parts are stacked, and which, in the normal closed position of the door, rests upon the door sill portion e of the door frame member E. The memn ber R also comprises an uprising portion R2 adjacentthe plate K and detachably connected to the latter by bolts R3. Advantageously also, the member R includes gusset or side plate portions R4 at the opposite side edges of the door between which the brick parts at the bottom of the stack are received. The brick supporting portion R of the member R is formed at its upper side with a recessed seat R for a metallic post s. The latter extends to the top of the plug section of the door and has its upper end loosely received in a recess M2 formed for the purpose in the part M. In the preferred construction shown, the post s is of T bar cross-section with the base of the section at the side of the post remote from the sealing member K.

The brick parts Q, Q and Q2 are suitably shaped to interlock with one another and with the post s which they collectively surround. As shown, one brick part Q and one brick part Q are located at each of a plurality of different levels and constitute the body portion of the plug section briokwork. One of the two parts Q and Q at each level extends from one side of the plug section of the door into overlapping relation with the post S and into abutting relation with the other part of the pair, which is also in overlapping relation with the post S and extends to the opposite side of the door. As shown, each ofthe parts Q and Q includes a portion q at the outer side of the door extending into proximity with the web or leg of T bar section of the post S and extending in front of the corresponding portion of the head of the post section. Each brick part Q' includes a portion at the inner side of the post extending past the latter.

The brick parts Q and Q' are each recessed to receive a corresponding portion of a corresponding brick part Q2 by which the brick parts Q and Q are locked in place about the post S. As shown, the bricks Q and Q in each of two adjacent horizontal layers or courses, collectively form a horizontal channel extending from the inner side of the door to the adjacent side of the post S, and shaped to receive and be filled by a corresponding brick part Q2. Each brick part Q2 is formed with ange portions` or ribs extending horizontally in the direction of the door axis and projecting away from the top and bottom faces of the brick Q2 at the side edges of the latter. Each brick Q2 is thus in effect a tenon dovetail part interlocking with two brick parts Q and two brick parts Q', all of which are thereby held against significant horizontal movement relative to the post S. Since in the normal manipulation and use of such doors the latter are maintained vertically or substantially so, it is not necessary to provide interlocking provisions preventing horizontal movement of the locking brick parts Q2 away from the T bar S, between which and the inner face of the plug door section, each part Q2 extends. Friction is sunicient to hold those parts in place, even though the plug section brick parts are not laid with mortar, which may or may not be used.

The particular door shown in Figures 1, 2 and 3 is a pusher side door, and is provided at its top with a casting h for the usual levelling bar opening or doorway ordinarily provided in pusher side doors. As will be apparent to those skilled in the art, the seat for the upper end of the post S might be formed by a recess in the casting h, but I consider it preferable to provide a special part M as shown, in which the upper end of the post has its seat. In the preferred construction illustrated, the top bricks Q and Q and a portion of the interlocking brick Q2 are above the top of the post S, the bricks adjacent the part M being specially formed or chipped away to provide space for that part. The details just mentioned and the differences in respect thereto between the coke side and pusher side doors are without real significance in so far as concerns the essentials and principles of the present invention.

The brick parts Q, Q', and Q2 are disposed so as not to interfere with some relative movement of the post and brick parts as the door is heated and cooled. To this end, cardboard of suitable thickness may advantageously be interposed between the post S and the adjacent brick surfaces in the initial assembly of the door. To insure suiicient iiexibility and freedom for adjustment of the sealing member part K, the latter is suitably spaced away from the outer face of the plug section of the door, and to this end cardboard o1 suitable thickness may well be interposed between the plate K and the plug section of the .10 door in the initial assembly of the latter.

In the door construction illustrated in Figures 5 to 10 the intermediate section or plate KA has welded to its edges a sealing flange or strip K having its inner edge bevelled off at K11 and a '1'5 plurality of adjustable clamping devices N10 are provided which connect the flexible door element KA to the rigid outer frame section I-IA.

In the construction of Figures 5-10, the iiexible element is suspended from a shaft L carried by the outer frame member, exactly as in the construction first described, but preferably the flanged bar K7 carrying the hinge lugs K0, is welded to the plate KA, or is secured to the latter by bolts or rivets separate from the bolts M11, which are employed to detachably connect to the plate the part M10, shown in Figure 8, which replaces the part M previously described. The plate member KA carries at its lower end a rigid brick supporting member R10, similar in its general 30 purpose, and shown as generally similar in form, to the part R of the construction first described. In the construction shown in Figures 5-10, however, the bricks forming the refractory portion of the door, do not bear directly against the horizontal lower portion of the member R10, but on a removable casting plate T. The latter, as is plainly shown in Figures 9 and l0 is formed with a notch T receiving the bar S in the assembled condition of the plug section of the door. The plate T is also formed with notches T2 in its opposite side edges which, in the assembled door, receive lugs or projections R0 of the member R at the bottom of the latter and thereby hold the plate T against horizontal movement relative to the supporting casting R10. While the notch T is shaped to permit free movement of the plate transversely of the bar into and out of its normal relation therewith in the assembled condition of the plug section, the plate T is interlocked against movement relative to the bar by a transverse plate or foot part S10 welded to the lower end of the bar and normally received in a recess T3 formed in the underside of the plate T. rEhe brick parts of the plug section shown in Figures 6 and 8 comprise brick parts Q10 and Q11 which may be exactly like the brick parts- Q and Q2 previously described, and are similarly interlocked by brick parts Q2. As shown in Figure 7 a specially shaped head brick Q13 forms the top of the plug section of the door being recessed at its end side to receive the upper end of the bar S. The previously mentioned metallic part M10 is interposed between the head brick and the subjacent bricks which are recessed to receive the plate and the latter has welded to its outer edge the previously mentioned bolts M11 by which the plug section of the door is detachably secured to the intermediate exible section or element of the door.

As will be readily apparent, the plug section of the door, except for the head brick Q13, may be readily assembled to form the unit shown in Figure 9 with the bar S vertically disposed, or, conveniently in some cases, with the bar S horizontally disposed in an assembly rack or cradle not shown, but adapted to facilitate the assemblage of the brick and metallic parts. The unit thus formed may be transported bodily as by means of a crane or hoist having a hook adapted to enter the hole S12 formed for the purpose in the upper end of the bar, the foot portion S10 then preventing down movement of the refractory blocks and plate T, relative to the post S. The plug section unit may thus be readily moved into and out of its normal position at the inner side of the member KA. In they normal condition of the door, the plug section is held against horizontal movement relative to the casting R10 by the projections R6 of the latter received 'in the notches T2, while the top of the plug is anchored in place by the part M10, through which the bar S passes, and the bolts M11 by which the part M10 is detachably secured to the member KA. `The head brick may be readily put into place or removed to expose the hole S12 in the bar S when occasion requires.

The door shown in Figure 5 is intended for use at the coke side lof the battery at which the coke is discharged, and hence does not include provisions such as the casting h of the pusher side door construction first described, for a levelling bar or poke hole. As those skilled in the art will understand, the special features of each of the door constructions illustrated, may be used equally well in a pusher side door, as shown in Figure 2, or in a coke side door as shown in Figure 5.

Certain novel features of coke oven door construction and arrangement disclosed, but not claimed herein, are disclosed in one or the other of my prior applications, Ser. No. 977, filed Jan. 9, 1935, and Ser. No. 52,995, filed Dec. 5, 1935,' the present application being in respect to a portion of its subject matter, a division of one of said prior applications and being a division of the other of said prior applications in respect to the remainder of its subject matter. Accordingly, the present case may be termed a continuation-in-part of each of the two above mentioned applications.

While in accordance with the provisions of the statutes, I have illustrated and described the best forms of my invention now known to me, it will bei 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 in some cases advantageous use may be made of some features of the present invention without a corresponding use of other features.
