HEATING-WALL FOR COKEOVENS AND THE LIKE.

Specification of Letters Patent.

Patented Dec. 6, `1921.

Original application filed September 15, 1916, Serial No. 120,351. Divided and this application led January 27, 1919.

To all whom it may concern Be it known that l. ARTHUR ROBERTS, a citizen of the Unit-ed States, residing at Evanston, in the county of Cook and State of illinois, have invented certain new and useful improvements in Heating-Walls for Coke-Ovens and the like, of Which the follovving is a specification.-

The present' invention has todo With certain improvements in heating Walls for coke ovens and the like, although it will presently appear that the features of the invention are in no ivise limited to use in connection with heating Walls, but may be used with equal advantage in the construction of other coke oven Walls.

ln my co-pending application for Letters Patent of the United States on iinprovements in coal distillation retorts, Serial No. 120,351, which was filed September 15, 1916, l have shown a construction of coke oven Wall which is provided on its interior por-4 tion With-a nieshvvork of interconnected gals passages extending in zigzag fashion throughout the desired portion of the wall. The Wall construction illustrated in the said application is one which is built up from blocks notched in a peculiar manner, so that, when said blocks are set together in the construction of the Wall, the aforesaid' notches will cooperate to provide the desired network or ineshwork of interconnected pas sages.

This application is a division of the aforesaid application, Serial No. 120,351, and has to do particularlyvvith the construction of the Wall and the blocks from which it is built. The Wall and block construction to which this invention relates are very Well adapted for use inthe construction ,of vertical retort coke ovens of that type in which the heating gases pass through the heating Walls in a generally horizontal direction.`

lvWhich through the wall from its face 7 to its face A8. The blocks are ordinarily laid up in Serial N o. 273,230.

they are constructed that a similar result will be secured in case the gases are caused to traverse the wall in a generally vertical direction.

Other objects and uses of the invention will appear'froma detailed descriptionof the saine which consists in the features of construction and combinations of parts'hereinafter described and claimed.

In the drawing:

Figure 1 shows a horizontal fragmentatgv section through a portion of a heating wall.

embodying the features of the present in?` vention, being a section taken on theline l-l of Fig. 2,looking in the direction oft'h arrows;` l

Fig. 2v is a fragmentary vertical section taken on the line 2-2 of Fig.

the direction of the arrows;

Fig. 3 is afraginent'ary vertical cross secl tion taken on the line 3 3 of Fig. 2, looking in the direction of the arrows; Fig. 4 is a detail plan view of one of the 1, looking in blocks used in the construction of the wall;

F ig. 5 is a detail side elevation corresponding to Fig. 4; and

Fig. 6 is a cross section taken on the line 6-6 of Fig. 5, looking in the direction of" the arrows.

Referring to the construction shown in thev several drawings, each of the blocks vfrom the wall is constructed extends courses in the manner shown in Fig. 2, and ordinarily said courses will extend in a horizontal direction.

Each block has'thecentral portions of its four corners recessed as at 9, 10, 1l, and 12, so that, when the different blocks are set together in the courses, the recesses of the various blocks will coperate to provide a series of zigzag passageways 13 interconnected in both horizontal and vertical directions.

It will be observed that, when the courses break joints, as is shown in Fig. 2 in particular, the passages 13 are so related that gases traversing the Wall in a generally verf tical direction, are of necessity caused ,to baille or swing backv and forth in a zigzag fashion. In order to secure a similar result in case the gases traverse the wall in a generally horizontal direction, I khave llustrated the following expedient.: That-is,.the

`1 compelled to pass lower central portion of each block is extended down below its lower end portions to provide a tongue 14, the tongue of each block entering the space provided by the upper recesses of the two adjacent blocks of the next lower course. The tongues 14 in this manner make it impossible for gases to traverse the wall in a generally horizontal direction without bailing back and forth so as to cause the gases to impinge with violence repeatedly against different portions of the wall.

While I have herein shown and described only a single embodiment of my invention, still it will be understood that I do .not limit myself to the said embodiment, except as I may do so in the claims.

I claim:

1. A coke oven heating wall comprising courses vof blocks, the courses breaking joints with each other, each block having its four corners' recessed to rovide, in conjunction with the adjoining locks a series of passages extending in zig-zag fashion between the blocks of the successive courses, and each block having in its lower central portion a downwardly projecting tongue entering into the space between the recesses of the two blocks immediately `below it, whereby gases traveling lengthwise of thewall are compelled to passaround said tongues, and are therefore compelled to travel in-a zig-zag fashion, substantially as described.

2. A coke oven heating wall comprisingv courses of blocks, the courses breaking joints with each other, each block having corner recesses coperating with other blocks to provide passages between the adjacent blocks, and each block having a downwardly projecting tongue on its lower; portion depending into the block recess below, whereby ing course, whereby communication is estabgases traveling lengthwise of the `wall are l beneath the tongues, and are therefore compelled to travel 1n azigzag fashion, substantially as .-de'scribed.

3. Aicoke oven heatingf'wall comprising courses 'ofV blocks having their' corners recessed, the recesses fof) the'fiblocks of each rection transversely fashion lengthwise of the wall,l substantially as described.

4. A coke oven heating wall comprising courses of blocks, each block having the central portions of its side faces recessed4 and having in the 4centralportions of its four corners recessesv communicating with the side recesses, the blocks of each course breaking joints with the blocksof the courses immediately above and below, the combined width of the adjoining recesses of the blocks of a course being-greater than the width of the opposing face of the block of they ad joining course, whereby communication is established through the wallina zig-zag manner inthe direction the courses through the medium oftheucorner recesses, and whereby communication is established through the wall ina zig-zag manner in a diofthe course through the mediumof the side recesses, substantially as described.

5. A coke oven courses ofiblocks, eachblock having recesses 'in the, central portions of selected corners,

the end portions of ythe'blocks'of each course being in direct contact with the end portions of thebloeks ofthe adjoining courses,

`the blocks l'of' each course breaking joints with/the blocks ofthe courses immedlately above and below, the combined width of each recessed opening of the blocks of a course being Y,greater than the width of the opposing face of the blocks of the adjoinlished through the wall in a zig-zag manner in the direction o fy the course through the medium of the'corner recesses, substantially as described.
