LEVELING-RAM F033. 'COKE-OVEN S.

Specification of Letters Patent. lPatented Jan. 17, 1911.

Application ld'ocmber 15, 1310. serial No. 587,174.

To all 'whom it may concern:

Be it known that I, LOUIS WILPUTTE, a

subject ofthe Kingdom of Great Britain,

resi-ding in Joliet, in` the county of Will andV State of Illinois, have invented -a new and useful Improvement in LevelingeRams for Coke-Ovens, of which the following is a specification.

The object of this invention is to provide for lessening the loss of gas during the operation of leveling the charge in coke ovens, and relates to the means for accomplishing this result, consisting in general terms of a housing, or containing the leveling ram, to be joined in a gas-tight manner to the opening in the ovenwhile such leveling opera--4 tion is going on, so that t-he leveling ram operates in an inclosure of which the oven 1s a part, thus greatly diminishing the escape of the gas toy the outer air and its consequent loss during `this time; and it yfurther consists in the novel devices and parts, and

` combinations of parts and devices, substany ing forms a part of this specification.

tiallyas hereinafter described, and shown in the accompanying drawing,which draw- In said drawing Figure l is a plan View of an apparatus embodying my invention; Fig. 2 is a side elevation of the same; Fig. 3,-upon a somewhat larger scale,is a plan view of'a portion of the leveler ram indieating its construction more in detail; Fig. et

is an elevation of the same; and Fig. 5 is a cross section. thereof.

Like letters of reference indicate like parts wherever employed in the several figures.

The modern cokeovens, as iswell known to those skilled in the art, are built in proximity to each other, a number side'by side, for convenience of operation and other economiesl Along both faces of this multiple structure are built tracks upon which to run cars or locomotives; at one face` the cars into which the finished coke is discharged and quenched, and at the other face a track for the locomotive staging upon which is mountl ed the pushing ram for discharging the coke from the oven,and, sometimes also, the levelingram whichisrn'n into and reciprocated along the .uppenpart of the oven to level the freshlyzdeliveredgcoal which, as it is fed in .atseverall openingspintheroof, lies in heaps,

thusgto,-bringtthenppersurface: of said 'coal tok a comino';n horizontal plane to facilitate and-'equalize the coking. This leveling ram may however, be mounted on a separate locothe better way', especially where the ovens are numerous. These locomotive ystagings are usually provided with a cab toprotect the driver from the weather, and are moved from pointto point on the track bymeans of an electric motor controlled by the driver from within said cab. Theyare also fitted With such motors for reciprocating the pushing ram and the leveling ram, one or both as the case may be. In the facevof the oven at this side is the large opening `through which the head of the pushing ramis admitted to pass into and V,through the oven chamber to push out the finished coke, and which opening during the coking is closed witha gas-tight or luted door. Above this large opening and near the upper part of the oven chamber is a' smaller opening or leveling hole to permit the entry into the oven ofthe leveling ram, closedk during the coking by a' gas-tight or luted door. This smaller door to admit the ram is necessarily opened after the coal has been fed Ato the oven 'chamber and the coking begumftrnd consequently at a time when the gases are being freely and abundantly evolved and standing injthejupper part of said oven so thatiwhenthe door lis opened to admit the leveling ram and vall during the operation of leveling 1 the.,` gas rushes continuously gout into theatmosphere and a large amountnof it is., thus lost@ And as will be remembered theffutfilizatin of theseV gases as a, v'aluable-by-produjct of the coking is, and has been the chief things soughtan modern-lcoking. 'Io remedy this 'co'nditiorrg;.IyA have t devised my gas-tight', or practically gas-tight,-hous ing .orl casing for 4the levelingf rami 'llli'efffeal` tures of such a housing-@asdeveloped,`f-are the following :-It inclo's'es or ;hous"esth'e entire ram, in` a practicallyy gasetightchar ber, at `least `-while the operationrof; leveling is being performed. It is-v capable `of ready application; tothe leveling hole tomake'a reasonably tight-jbint-there; cIt embodies 3a pocket to receive the dislodged coalgpulled. out of the, oven'by the act'ionfofihe ram-@or by its withdrawal. The structure' 3doesnot interfere with theoperation ofy the: ,ov-en* or the closing andv opening of the doors thereof. These ,are the principal advantages or re'- quirementsg-sot-hers of lesser .note will appear as the description lis lhereinafter further given. It?l xvliiljlwbe understood, b v those skilled in the art, that the making of an ab- Solutely gas-tight removable chamber to contain the leveling ram' and to beapplied to and removed from the leveling hole 4of the.

'of the oven;' 11 the opening to admit the' passage of the" discharge or pushing ram; 12 the leveling hole to permit the passage into the upper part'of the oven ofthe leveling ram; 13 the-doorl for closing the said levelingI hole; 14 is the platform or walkway for the workmen who' attend to the opening 4and closing of the openings 15 is the overl head track for carrying the-clay for luting,

' etc.; 16 thetrack on which runs the locomotive staging carrying the leveling raml and its mechanism at the will 'of the driver from oven to oven; 17 'isjthe locomotive staging; 18 the cab =carried .thereon for sheltering the driver 19'the electric motor for driving the llocomotive staging and'controlled from within the-eab. Upon the locomotive staging is erected the frame-work 20, for supporting l the leveling ram and` itsl housing.'

"Ihele'velingv ramj is shown at 21. f' It is` made of two long side pieces 211, 212, conf "nected together bythe zig-za bracing strip 21,3 riveted at alternate ang es to one and to the other of the side pieces, as will be better understood by reference to the detail Figs. 3, 4 and 5 pf thel drawing. The side pieces' 211, 212,' at'theirl forward ends are showntapering/from below upward 'so that the portion that y.first enters the oven shall be Vthe smaller. And, below #the zig-zag brace 213ithe said ram is. provided with a seriesfffross-bai's 214, each having a friction l'sleeve' Aor roller 215,the series forming a rack' to, be engaged by the driving pinion 2.2,'` constituting 4a means by which said ram may be .moved'in and out of thefoven and rec1procated while within the oven chamber. Th'p'inion 22 is driven in either direction by the electric motor 23, through gears, and controlled froxnwithin the cab. That the driver may? knowwhen to reversethe mechanism so that. the leveling ram shall not be run in or drawiimt too far, an indicator device to be ,observed,"`-`may vbe employed, such for ex ample as the bell 221 to be'struck and sound "ed in both `directions byx the projections 222, 223, which may also preferably be so placed as to beseen by the eye of the driver to indicate to him the position of the ram in case the bell does not sound or is .removed for any cause. That the ram may move freely, and

p withoutbi'riding, friction rollers 224 are provided for supporting the same above and below.

The housing or extensible chamberfor inl closing the leveling ram is shown at 24. .It is supported preferably labove the cab on `riding upon the surface ofthe ram, and

when the ram is moved forward toward the oven far enough to enterv the same yit gets out from under the door which thus closes of its own weight and Amakes the housing or chamber at' this end practically lgas tight. To-prevent-wear and facilitate this action, the door 25is provided with friction roller 251 that rides on the surface of the ram during the movement of the latter. In front of the cab and nearer the front end ofthe housing it will be seen that the housing or chamber is provided with pocket. 26, having an inclined floor 261 near the lower end ofj which is. a door 262. AI portion 263 of the ioor at the front is inclined in the other direction. The purpose of. this pocket is to catch whatever coal may be incidentally and un'- intentionally pulled out of vthe oven",l and into the housing by theI action of the level- 7o l v4the framework of the locomotive staging,

`ing ram, either in its leveling reciprocation withinthe oven or'in its withdrawal therefrom, and to retain said incidental coal until after-the ovens have been leveled, when itmay convenientlybe discharged from said pocket by the opening of the door 262 ,above referred to. The front end of thisfhousing is so contrived that it may be moved or exaccommodate its application and removal from the oven .and to permit the locomotive lthe-:front end of the stationary part and. the

rear end of the movablepart of lthe housing,

Itended to a certain amount, suiicient to both open, are made inclined with opposite inclines 244, 245, and that a wedge-shaped intermediate section 246'is movably interposed betwcenthese two inclined ends. The result is that when the wedge-shaped intermediate section is lifted out of place. the extensible .part of the housing may be moved freely .aback and farai; anaehat when the housing is fully extendedv the Wedgeshaped intermediate sectionfmay be lowered intohplace andgjivedginghomer a practically gas tight continuation of the housing passage is produced. This construction is such 'as will be understood 'by those skilled in the art that the operation is not materially interfered With by the deposit of gastar which takes place in appliances used in this relation. To extend and Withdraw the movable part of the housing racks 247 and pinions 248 are Provided, the latter operated by a crank 249 Within the cab connected bv pulley and chain with the pinions 248. Anch to raise and lower the Wedge-shaped intermediate section a chain 2461 is carried from the'pulleys 2462, 2463, to a crank 2464 in the cab, a counter WeightA 2465- on said chain tendingto counterbalance the Weight of the said intermediate section. vand thus render the operation of lraising and lowering thev framing around Asaid levelinghole and makes a practically close joint; then by the aid of -the other crank he lowers into place the wedge shaped intermediate section thus making a continuous close housing from the oven 4back tothe rear end 'Where 'the inclined door still' remains open; but immediately and as soon4 as vthe joining is thus complete the driver starts the leveling ram motor to going which rapidly moves the forward end of i said ram into the oven and runs .the rear end Within 'the housing permitting the inclined lvalve door to close said rear end of the housing. lVhenl the front end of the ram has gone in far enough-the bell rings and e. driver then reverses the-motor and runs it back and forth in the 'oven with a reciprocating stroke of about five' feet, more or less, until the coal is perfectly leveled, the zig-zag braces serving to rake the coal and distribute'it evenly in the oven top into proper shape for even and regular coking. The leveling having been thus accomplished, the ram is quickly withdrawn and run back lto its limit, the intermediate section lifted,

andthe extensible'section Withdrawn, leav ing theleveling hole clear so that the asslstvant on the oven plat-form may close the same. Such coal as may be Withdrawn aceidentally by the action ofthe ram falls into the retaining pocket and by its inclined bot-- torn is discharged ata convenient time and Although some glas operation. itl will be seen that by the .use of l .as

place throughthe. discharge door in the bota tom thereof. Vhen the 'housing lis" Witl1 drawn the driver may immediatelyfstart the` locomotive moto-r and move the staging into position forthe next out the series. l t w is lof course losty inffthe this apparatus much escape of gas is "prevented. i
