FREDERICK PEITER, OF CLEVELAND, OHIO, ASSIGNOIR, TO THE GAS MACHINERY COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO RUPTURE-PREVENTING STRUCTURE.

Specification of Letters Patent.

Application filed April 23, 1913. Serial No. 768,155.

which heat-is applied, and in which the amount of contraction and expansion of the walls or arts affected by the heat varies. The ob ect of the invention is to provide I a structure of the above described'eharacter,

which 'will be so arranged as to prevent rupturing of the parts such as would produce leakage or other deleterious results.

The said invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawing and the following description set forth in detail certain means embodying my invention, the described means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.

In said annexed draWingz-Figure 1 is a transverse section of a fra mentary portion of a coke-oven embo ying my invention. Fig. 2 is a longitudinal section of said fragmentar portion of said oven,

taken upon the plane indicated by line I II in Fig. 1. Fig. 3 is a fragmentary lon gitudinal section taken upon the plane indicated by the line III-III in Fig. 1. Fig. 4 is a fragmentary horizontal section taken upon the plane indicated by line IV-IV in Fig. 1.

The illustrated structure comprises a plurality of vertical and longitudinally extending cokinghambers 1 intermediately of which are located the heating or combustion- I erence chambers 2. These combustion-chambers communicate with fuel-ducts 3 into which the gaseous fuel is discharged through suitable nozzles 4. Suitable air-ducts 5 are provided for 'supplyin the necessary air for combustion. In so ar as concerns the above described elements, any desired or suitable structure may be adopted.

As shown in the drawing,'the cokingchambers 1 extend upwardly beyond the upper ends of the heating or combustionchambers '2. Brick walls 6 separate the coking-chambers from each other as shown and extend upwardly to the top of the structure. each coking-chamber is a closure-structure which consists of a lower silica-brick element 7 above which is the brick element 8 on top of which is the brick element 9,

Between these walls and above,

upon which rests the uninclosed red-brick element 10. The sides of the silica-brick element 7 are separated from the brick walls by longitudinally and vertically extend: ing spaces 11, Fig. 1, as are also the sides of the elements 8 by similarly extending spaces 12, staggered with refto spaces 11. The red-brick element 9 is divided and the two parts separated by a longitudinally and vertically extending space 13, which, as is seen, is staggered with reference to the spaces 12. In thus staggering these elements liability of leakage is reduced to a minimum. In constructing this closure-structure, sheets of paper 14 are placed between the element 10 and the element 9, between the element 9 .and the element 8, and between the elements 8 and 7 .as'shown in Fig. 1. Similar sheets 15 are also placed between the element 7 and the brick wall as shown in the Fig. 1. Similar sheets 16 are also placed between the brick walls 6 and the sides of the elements 9 as shown; These sheets of paper exclude the cement or mortar used in constructing the brick work and prevent the adjacent elements from adhering to each other, as will be understood. This paper burns out after the oven is in operation and leaves these elements free to move relatively to each other while practically in contact and making a substantially gas-tight joint. That portion of the brickwork of the wall 6 above the horizontal plane of the top of the chamber is integrally united with the lower portion thereof, but is divided transversely and vertically into a plurality of parts, sheets of paper 17, Fig. 4, being used c uring construction, as described in connection with the closure-structure to form slipjoints as in the case of the closure-structure. It will therefore be noted that the wall-structure which forms the laterally inclosing walls for the closure-structure is divided into a plurality of elements which are separated from each other by transversely and vertically extending spaces.

During the operation of the oven and as is well understood by those skilled in the art, the variation of the degree of heat to which the parts of the structure is subjected, is such as to cause a variation in the degree of expansion and contraction. Those parts near the hottest zone of course expand to the greatest degree, and this degree of expansion decreases upwardly away from this zone. The greatest amount of expansion takes place longitudinally in the walls immediately adjacent to the heating or combustion-chambers. The least amount of expansion takes place in that part of the closure-structure which is closest to the outer atmosphere and from which heat is therefore more readily radiated and conducted. Of the closure-structure, the element 10 expands the least, the element 9 is subjected to the next greatest amount of expansion "and the elements 8 and 7 then follow, the element 7 expanding most. Since these elements are all separated as shown, slip-joints are formed and this difference of expansion does not effect the integrity of the structure and rupture is thus prevented This closurestructure expands not only longitudinally but'also laterally. The provision of spaces 11, 12 and 13 permits this lateral expansion without causing the closure-structure to bind on the wall-structure above the plane of the upper end of the coking-chambers, andtherefore also permits the divisions of the said wall structure, formed as previously describede to readily move longitudinally as a result of the longitudinal expansion-of the Wall-structure immediately adjacent to the coking-chambers and heating-chambers, without interference from said closurestructure. Perfect freedom is therefore permitted all of these parts, even under condi tions of Widely varying expansion and contraction and I am therefore enabled to 0perate an oven embodying the above described arrangement of parts without effecting rupture and therefore without producing leakage as a result of such rupture.

Having fully described my invention, what I claim and desire to secure by Letters Patent is 1. In acoke-oven or the like, the combination of a pair of adjacent coking-chambers; a vertical intermediate wall-structure; and a closure-structure above each such chamber and consisting of a plurality of relatively movable elements; that portion of said structures lying in planes above the tops of said chambers being divided transversely into a -plurality of separated parts; one element of said closure-structure being capable of'yielding in a transverse direction.

2. In a coke-oven or the like, the combination of a pair of adjacent coking-chambers; an integral briclmvork wall-structure separating said chambers; a closure-struc ture above each such chamber consisting of a plurality of relatively movable elements; and a wall-structure, divided into a plu- .rality of parts separated from each other transversely, and forming a lateral wall for said closure-structure; one element of the latter being capable of yielding in a transverse direction.

In a coke-oven or the like, the combination of a pair of adjacent coking-clnnnbers; a vertical intermediate Wall-structure and a closure-structure above each such chamber; that portion of said structures lying in planes above the tops of said chamber being divided transversely into a plu rality of separated parts; said closure-structure being divided into a plurality of parts separated from each other longitudinally.

4. In a coke-oven or the like, the combination of a pair of adjacent coking-cha1nhers; an integral brick-Work wall-structure separating said chambers; a closure-strncture above each such chamber; and a wall-structure united at the bottom with the top of said integral Wall-structure, divided into :1. plurality of parts separated from each other transversely; and forming a lateral wall for said closure-structure; the latter being divided into a plurality of parts separated from each other longitudinally.

5. In a cokeoven or the like, the combination of a pair of adjacent coking-chambers; an intermediate wall-structure; and a cl0sure-structure located between the plane of the ends of said chambers and the plane of the outer corresponding extremity of the even; said wall structure forming walls for said closure-structure; the latter being disconnected from said wall-structure, whereby the latter may expand longitudinally and independently of said closure-structure.

6. In a coke-oven or the like, the combilongitudinal movement independent of said closure-structure.

Signed by me, this 10th day of April 1913.

FREDERICK PEITER.
