COKE OVEN.

Specification of Letters Patent.

Patented Dec. 31, 1907. I

Application filed May 15, 1907. Serial No. 873.721.

To all whom it may concern.

Be it known that L-ARTHUR OWEN J oNns, a subject of the King of Great Britain, residing at New Brancepeth, in the county of Durham, En land, have invented certain new and usefu Improvements in Coke-Ovens, and of which the following is a specification.

This invention relates to that type of vertical coke ovens in which the material tobe treated is charged through the top and removed through the base when coked, it having a removable sole to close the said base and having heating flues extending around the oven in horizontal planes.

The present invention relates to the construction and combination of parts composing the improved vertical coke ovens hereinafter described and claimed, which can be charged at one operation with the material to be coked and without having to level the top of the material, while the horizontal heating fiues surrounding such an oven are .entirely separate from one another and each separately and .controllably heated, and also all theseparate horizontal flues of each oven open into a vertical outlet flue belonging to that particular oven, while the top part of each oven is'prevented from becoming overheated by means of an air circulation passed around it through horizontal circuitous passa es.

he invention will be fully understood by the following description with reference to the accompanyin drawings which illustrate ovens constructe according to the present invention.

' Figure 1 is a vertical cross section through one of the ovens in a bank or series. Fig. 2- is an elevation of a portion of the front wall of the series. Fig. 3 shows horizontal sections taken in two planes, the upper part of this figure being a section through the ovens and heating flues on the lines X, Y, of Fig. 1,

and the lowerpart of Fig. 3 being a section on the line X, Y of Fig. 1 showing the circuitous air passages.

Each vertical oven 1 is rectangular and oblong in plan as shown at Fig. 3, of consid-- erable length in proportion to its width, and the char ing opening at the top of each oven is of the ull size of the oven, and is fitted with a hin ed or other cover 2 wholly removable,

and t e base of each oven iscapable of being closed by means of a sliding sole plate 3, car-' ried in guides and operated by any suitable means, being generally made to slide beopen top of each oven.

neath the oven, and then to be raised, by means of screws or other devices, into contact with the under-surface of the oven.

A hopper wagon 4 is capable of being traversed upon rails 5 mounted upon the front and rear walls 6, 7, of the series of ovens, outside the fireclay lining 8 thereof, and the size of the opening of the we on for discharging its contents is equal to t e full Since the wagon is made to contain a full char e for'an oven, it will be clear that when it is rought' over the full open top of an oven and the hopper is opened, that oven will receive instantaneously a complete charge, and owing tc the narrow oblong form of the ovens in plan, the inclines of the top surface of the charge will not present such angles as to call for any leveling of that charge.

The separate horizontal heating flues 9 (Figs. 1 and 3) are constructed in the fireclay lining of each oven, and enterin each flue from the front of the oven (see ig. 3) is a burner 10 through which the combustible mixture of air and gas is projected down one side of an oven, passes along the back, along the other side, and over the front, and the front ends of each of the horizontal fines of.

an oven communicate with a common vertical outlet passage 11 for that oven. Each 'of these common outlet passages 11 has a channel 12 (see Fig. 1),controlled by a damper 13, the channels 12 all leadin into an uptake flue 14-common to the who e series of ovens.

.The burners 10 are su plied with gasobtained as usual from-tile product being treatedby means of a gas main 15 an branch pi cs 16 to which each burner is con nected, t e admittance of gas from the branches 16 to each burner being controlled by valves 17. the burners from a main pipe 18'and branch pipes 19, the connections between the branch pipes and the burners being alsofiaontrollable by means of valves 20.

21 are sight apertures.

Circuit-ou's base of the ovens. Into these passages air is admitted, and circulating therethrough, passes up vertical passages 23, formed at lntervals in the front wall of the bank of ovens. The vertical passa es 23 communi cate at their upper ends wit circuitous horizontal passages 24 formed in the lining of the ovens near the to s of the sameas shown at Fig. 3, and circu ating through these pas- Heated air is also supplied to passages 22 are formed in the with whic I the gases evolved,steam from a pipe 26can as set'forth,

length in proportion to its width, having a full open top, having vertical outlet sages, the air is finally conducted to the] heated air supply mains 18 (Fig. 1). The air passing through the passages 24, while thus becoming heated, has a cooling action upon the trips of the ovens, that is, it has a cooling effect sufficient to prevent the tops of the ovens becoming too highly heated and thereby'bringing about the decomposition l of the gases evolved from the material being coked.

Pipes 25 are provided for taking off the gases from the tops of the ovens evolved during coking, and these gases are passed through ordinary by-product recovery apparatus as is common, and are subsequently led to the gas supply main 15. To still further prevent decompositionmf be admitted to the upper portions of" the ovens by branch ipes. The coked product isautomatically ischarged by gravity upon the withdrawal of the sole 3, and falls onto an inclined hearth 2Z which directs it into trucks 28.,

I claim as my invention:

1. In vertical coke ovens ofthat type in which the material treated is charged through the top and renioved,'when coked, through the base, the combination of a seriesof such ovens, each oblong in lan and of great length inproportion to its width, having a full open top, having a series of heatin r flues in the Walls thereof, extending in horizontal planes around each oven, and having a vertical outlet assage in said walls for each oven l ioutlet passage all said horizontal heating fines of said oven communicate, means for supplying heating gas and air sep arately to said heating fiues and means for controlling said supply to each flue, a removable cover for closing the full open top of each oven, a removable sole for closing the base thereof, and rails mounted on the side walls of said series of ovens beyond the fireclay lining thereof'to support a wagon having a hopper opening corres onding to the length of the open top of sai ovens, substantially 2.
