To all 'whom it may concern:

Be it known that We, lnnnnnion EL Ben- DEL, a citizen of the United States, and loma BERGMANN, a. citizen of Germany, both residing in the city of St. Louis and State of Missouri, have invented a certain new and useful improvement in Cohe- VenS, of which the following is a tull, clear, and enact description, such as Will enable others slrilleol in the art to which it oppertains to make and use the saine.

bull: ci

`This invention relates to eolie ovens oi the type in which the chambers that receive the coal which is to be converted into coke are arran 'ed in an inclined position.

v@ne objectionable feature of coke ovens ont the type referred to `that are now in v`general 'use is that the coal chambers ci saine are of such forni that when the coai expands or swells, during1 the operation of driving oii' the gases, the top Walls of the coal chambers are subjectecl to abnorniai strains or pressures,l due to the increasevin the coal contained in the chanibe The main object of our invention is to provide an inclined. coke oven which is so designed that the top Wails of the coal chain bers will not be subjected to undue pressure or strains from the coal in same, during" the operation of converting the coal into coke.

ylilo this cnil wejhave clevisecl a coke oven equipped with one "or` more inclinei coal chambers, each oiwliicliis provided with top Wall which is so designed that the coal in the chamber can eXp-andi or svveli during n the coking operation, Without causing the coal to exert an abnormal or undue prcssrufc on the walls of the coal chamber.

Anti'anotlier object of our invention is to provide an inclined coke oven havingm a coal chamber that is provided with means :tor permitting,A the gases to escape therefrom at one or more points intermediate the ,ends ont the chamber.

on the line iiiw--li of i., the upper right hand portion ci? said View being takenv on the iine GMC oi Fig. i. Referring to the drawings, which illus-j trate the preferred form 'oi3 our inventinni '9 designates the coal chambers of the oven; which are arranged in an inclinedpositioinz. as shown. in lig. i, cach of said chambers being; provicleol at its upper end with a fend opening E); through which coal is introduced into the chamber anci provideci at its lower with a door 3 that normally closes a c scharge opening' through which the coke is reniovc Jlroro the chamber. The top wall oi each of the coal chambers 9, instead of being arrange@ parailel with the bottom wali of chamber, as has heretofore been the etico in inclined coke ovens, r in such a manner that the coai in sairi chamber will not Contact with the top Wall ci? the chamber throughout the entire area otisaicl top Wall when the chami ber ii'ilefl with coal, preparatory to the opera. on of heating the coal toconvert it into colic., Iilie top Wall of `the coal chaincan be formed various Ways Without nrting; iroin the spirit ci' our invention, in practice'we prefer to provide the top Waii of the chamber 9 with one or :more oii'sets G, so to iorin a relief space or spaces above the toti surface et thepile of coal in the chamber. lathe forni of our invention herein shown the portion Bot the top Wall ci@ the chamber 9 adjacent the lower enel (ii l ai chamber is spaced 'farther away from the bottom of the chamber than tv portion i of saicl top wall adjacent the opper endV of the chamber, thus producing the eiiset' ci in the top Wall that forms a reiie'f space above the tog surface of the pile oi' coal in the chamber. VVhen the bulk C coa'i in chamber 9 increases, .diie

parisien or snm of the coal, during le colring; opera the relieii space or' spaces above the top silrincc of the pile of coal permits the coal to shift sniliciently prevent the top Wall of the chamber 9 rein beine; sabjectecl to undue strains i in other Words, when the` coalcx nels, or swelis, some ci? the coal iviil be- 'orced upwith auxiliary gas outlet ports 17. In the form of our invention herein shown, in

which the .top wall of each coal chamber is provided with only a single offset `6, an auX- iliary gas outlet port 17- isy formed 1n the odset portion of the top wall, so as to per- Y mit the gases generated in the lower portion of the chamber 9 to escape therefrom freely. The gases that are generated in the upper portion 0f the chamber 9 escape there- C from through a conduit 1. If desired, the

auxiliary gas outlet port 17 intermediate the ends ofthe chamber 9 can be connected with the main gas outlet port at the upper end of said chamber by means of a gas passageway 5, as shown in Fig. 1.

The coal chambers 9 0f the oven are heated by gas generated 'in a gas producer located at the rear of the oven, as shown in Fig. 1, and provided with a fuel chamber 14 to which fuel is supplied through a feed opening 13 at the upper endfof said fuel chamber. Each of the coal chambers 9 of the coke oven is provided at its rear end with a coke discharge passageway 15 that is inclined downwardly, so that coke can escape through same from the chamber 9 when the door 10 at the lower end of .said passageway is opened, the door 10 being normally closed.` When it is desired to supply fuel to the producer, the door 10 of one of the coal chambers is opened, so as to per mit coke to escape by gravity from the chamber and enter a device that conveys or conducts the coke to the fuel feed opening 13 of the gas producer. Any suitable means may be used for conveying or conducting the coke from the coke discharge passageway 15 to the fuel feed opening 13 of the gas producer, such, for example, as a car 11 that .travels on rails' arranged at the rear side of the oven above the gas producer and provided with a hopper 12 into which the coke is discharged from the passageway 15 when the door 10 that controls said passageway is opened. A single car 11 may be used with a battery of coke ovens,`and after the car has been positioned properly with respect to the coal :hamber 9, from which the coke is to be taken, the hopper 12 of the car is filled with coke by opening the door 10 of the chamber, the coke passino; from the hopper of the' car into the .fuel opening 13 of the gas producer." This feature of the oven forms no part of our present invention, how- .we have herein illustrated said top tails of construction of the oven, other than the shape or form of the top wall of the coal chamber, are immaterial, and that whillt.

provided with only a single offset that forms a relief space above the coal, said to wall could be provided with a plurality o such offsets, or could be formed in various ways, without departing from the spirit of our 1nvention. Furthermore, instead of providing 'the coal chamber with only a single auxiliary gas outlet port, said chamber could be provided with a plurality of such ports arranged intermediate the upper and lower ends of the chamber, so as `to permit the gases to escape freely from different zones or sections of the coal chamber.

Having' thus described our invention, what we claim, and desire to secure by Letters Patent, is:

1. A coke oven having an inclined coal chamber that is adapted to be filled .with coal, the bottom wall of said chamber being straight orcontinuous and top wall of said chamber' being provided on its inner side with an offset for the purpose described.

2. A coke oven having an inclined coal chamber whose bottom wall is straight or continuous and whose top wall is rigld and composed of sections, the inner sides of which are located different distances from theA straight-bottom of the chamber.

3. A cokel oven having an inclined coal chamber whose-bottom wall is straight and whose inner top wall is composed of a plurality of rigid malalining sections so that when said chamber is lled with coal one of said sections will be spaced away from the upper surface of the ile of coal in the chamber, thereby providing a relief space that eliminates the liability of said top wall being subjected to undue strains when the bulk of the coal is increased during the coking operation.

4. A coke oven having an inclined coal chamber whose bottom-wall is straight or continuous and whose top wall is provided on its inner side, intermediate its ends, with an oi'set that connects two portions of said top wall whose inner surfaces are located different distances from the bottom of the chamber.

5. A coke oven having an inclined coal chamber Whose bottom wall is straight and whose top wall is rigid and provided on its inner side with an offset, located intermediete the upper and lower ends of the chamber, and a gas outlet formed in the odset portion of said top Wa'll. e

6. A. 'coke oven having a coal chamber 5 Whose bottom wall lies in a. continuous inclined plane, and whose top wall is composed o a plurality of sections lying in inelined planes didering from the plane of the bottom wall, and a substantially horizontally-disposed section joining said upper 10 inclined planes so as to form an offset for the purpose described.
