COKE-OVEN IRON WORK.

Speeication of Letters Patent.

Patented Nov. et, 1919.

Application filed May 27. 1938. Ser-iai No. 236,71.

1T 'o all whom t may concer/a:

Be it known that I, Lotus Vvniror'rn, a subject of the King of Great Britain, and a resident of New Rochelle, county of 1i/Vestchester, in the State of New York, have invented certain new and useful improvements in Coke-Oven Iron vl/fork, for which the following is a true and exact descriptipn, reference being had to the accompanying drawings, which forni a part thereof.

My present invention relates to the ccoiistruction of coke ovens and comprises iin-- provenients in 'the iron frame worlr or sectionalized armor commonly applied to the sides of by-product coke ovens having horizontally elongated cokingchambers running transversely to the length of the battery, with door closed ends at the opposite sides of the battery.

The general object of the invention is to provide a simple and effective frame work which will facilitate the operation of luting (sealing with clay) the joints at the margins of the removable doors closing the ends of the colring chambers, and which tend to insure joint loting of a desirable form, and to minimize the evil effects on the iron work and oven structure of sach failure of the joint seals as may be expected to occur from time to time in regular operation.

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

0f the drawings:

Fig. 2 is a partial section on the i ne 2-2 oi Fig. l. I u

Fig. 3 is a section taken similarly to Fig. 2 through one of the flash plates adjacent the end of the battery.

Fig. d is a partial section taken `on the line 4 4 of Fig. 1.

Fig. 5 is a plan view of apertion of the oven frame wjork.

F ig. 6 is an elevation of a portion or the apparatus shown in Fig. 5, and

Fig. 7 is a sectional elevation of a portion o f the iron work, the section being taken similarly to Figf, but on a larger scale, and snowing only a portion of the apparatus appearing in F ig. 4.

in the oven construction illustrated in the drawings, A represents the masonry oven structure proper which is formed with alternate horizontally elongated eoking chambers A', and intervening ue heating walls A2. The ends of the eoking chambers are normally closed by doors D, each of which comprises a metallic frame work D', and a body D2 of tire brick. At its sides each door is provided with ribs or flanges D3, which project beyond the margin of the door proper and abut against portions C of metallic parts C commonly called flash plates, which cover the ends of the hollow heating Walls A! and are interposed between the masonry ofthe oven structure and the vertical beams or buck stays B and B', which form major parts of the metallic frame work or armor of the battery. The two buck stays Band B in front of each heating wall are connected together by crossbraees B2, and the buck stays at the opposite ends of the heat ing wall are tied together by metallic tie rods running transversely to the length of the battery.

In so far as above mentioned, the construction shown does not eli-iler from construction well known and in general use. The flash plates C, as shown, diier from those heretofore used in that they are formed at their edges with outwardly projecting lips .or ribs C2. yThe ribs or lips C2 are shown as forming outer extensions of' transverse flanges which also extend outwardly from the flash plate bodies, and at their .inner edges, are odset in the usual manner at C to,l provide seats for the inner sides of the flanges D3 of the door. Preferably the transverse flanges of the flash plates and the ribs D3 of the door are shaped and proportioned to provide a comparatively narrow but deep tapered groove or channel at each side of the door in which the luting or joint sealing material H is packed. The lutng material H is ordinai-ily formed by clay a' 'f 'iedwhile in a moistened mortar like com" ion.

ing channel deep enough to receivev the proper vamount of luting .material and involves an economy in the use of the luting material inasmuch as they form an effective check against the tendency of the Workmen applying the, luting material to plaster the latterover a portion of the flat outer face of the flash plates C, Which is' commonly experienced With the construction hereto fore employed in which the flash plates are not-provided With the lips C2. The reduction in t e amount of luting material necessary to secure good join't seals, made possible by the use of the present invention, 1s of value in that it reduces the labor required for the luting operation, and reduces the amount of the baked luting clay to be removed in breaking the joints and preparing them for resealing when the coke is discharged from vthe oven chambers and the latter. are there- An even more important advantage obtained by the use of the flash plate lip C2 arises from the fact that When the luting joints fail, as they frequently do in use from the baking and cracking of the clay as the coking operation proceeds, the issuing gas which ignites as it enters the atmosphere, is prevented by the ribs C2 from wroking along the face of the flash plate, so that the gas flames do not come in contact with the adjacent b'uck stays. The impingement against the buck stays of the flames resulting froln the combustion of the gas issuing through cracks in the luting material itself, or other joint opening between the dried luting material and the ad- I jacent liash plate surfaces, which is avoided with the present invention, has been a frequent source of injury to the buck stays of coke ovens as heretofore constructed. With the present arrangement the gas llames, resulting from leaks through the sealing material, can do comparatively little damage, and moreover the cracks themselves may be easily located and closed, when serious, by the application of fresh luting material.

Advantageously, the pair of flash plates C, at the opposite sides of each coking chamber, are connected in an oven of the type illustrated by a metallic part or lintel E above the coking chamber and forn'xing the top portion of the door frame. Preferably the lintel parts should beconnected to the flash plates b v joints having sufficient flexibility or capacity for lost motion to accom.- modate the relative movcn'lents of the two flash plates at the opposite sides of a coking chamber resulting from the thermal eX- passion of the oven structure. The flexibility or l st1notion thus j )ermitted should. not be great enough, however, to permitany substantial movement of a lintel member relative to the other parts of a door frame under the forces to which it is subjected in the apparatus, lies in the plane of. the lips C ofthe adjacent Hash plates, and comprises pintlelike portions E5 at opposite ends, which are received in u notches C* formed in the "edges of the adjacent flash plate lips C. Each part E is also formed with lugs E6, which bear against ,the inner face of the corresponding flash plate lips C when the parts are assembled. The notches C4 of the flash plates and the pintle extensions E5 of the members E are so proportioned that the members E may be swung into and out of place as indicated in Fig. 7. The oven masonry is recessed as indicated at A4 to receive the body portion of the member E, and being further recessed as shown at A3 to/receive the lugs E and an 'inner stiffening fla-nge or rib E7 formed at the bottom of each member E. Each member E also comprises a portion E2 outwardly inclined from the body portion of the member and forming the upper wall of a luting channel )rovidcd between the member E and the ri oroutwardlyextendinglip l)4 at the top of the metallic portion ofthe corresponding door D. Each member `E is formed, as shown, with lugs E3 at the back of .the inclined portion E2 of the men'iber, and each lugr is notched as indicated at E4 4to receive a locking bar F, the ends of which' are also received in notches C formed in they transverse lianges of the corresponding flash plates C, the adjacent notches E4 and CG- registering when the member E is in its normal position. Each flash plate is formed with an inclined portion C5, which may be re* garded as an outturned portion of the corresponding flash plate lip C, and these flash plate portions C lie in the same plane with the portions E2 of the member E in the assembled condition 'of the apparatus. Advantageously as shown appreciable clearance is provided between the vertical and top edges of the notches C'i and the adjacent edges of the member E and between the lat ter and the registering edges of the flash plates above the notches C4 to give the desired joint flexibility. After each memberv E is put in place and secured by the corresponding bar F, the portion of the recess A4L above the member A is filled with moist clay or other similar luting material H. The material H is, of course, broken awayu and replaced by fresh material whenever a member E is replaced. The clay H`l prevents gas lcaka p c out of the oven chambers along the mem ersE.

The members lE \contribute to the formation of desirable joint seals at the top of 'age resultin Those skilled in the art will understand that the expansion of the oven parts may cause appreclable relative movements of the two flash lates C at opposite sides of the coking cham er. For instance on the expansion of the oven` brick work the flash plate at one side of an oven door may move up with the upper portion of the brick Work with which it is in contact for an inch or so while the other flash plate may not lift at all or may move to an appreciably smaller extent. The expansion of the oven mayalso cause a greater outward movement` of the upper end of one flash .plate than of an adjoining fiash plate. With the described method of one side.

connectin the lintel members to the flash plates s'uc relative movements of the upper ends of the flash plates may occur without resulting in any breakage of the flash plates, lintels or connecting-means. lt will be undel-stood of course by those skilled in the art that afterathe initial heating up of the ovens is completedand thereafter from time to time vas required the recess A4 is repacked with clay to .eliminate gas leakage and to more or less firmly anchor the lintel member in place though not holding the lintel in place with sufficient rigidity and strength to cause breakage on normal subsequent relative movements of the upperends of the flash plates. The flash plates CA adjacent the ends of the battery are made with a single transverse fiange with lips C and C2 at but Itwill be understood, of course, that the. fiash plate GA, shownA in Fig. 3, is for use at the Ileft hand end of the side of the battery shown in the drawings, and that a flash plate differing therefrom only in having its door frame edge reversed is employed at the opposite end of the same side of the battery. While in accordance with the provisions of the statutes I have illustrated and described the bestform of my invention noviT known to me, it will Abe 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 set forthin the appended claims, and that certain features of my invention may sometimes be used with advantage without a corresponding use of other Ifeatures.
