______.____ ______ __.______ _______________________ 1'he invention concerns an appara-tus for preventing the escape of gases when charg:ing coal cakes, into hori~ontal colcing chambers, said coal cakes produced in a ramming mould o:E a ramming, charying and pusher maehine outside -the coking chamber and standing on -the travelling ramming bo-ttom of the ramminy mould, in whieh ease the apparatus is desiyned as a tunne:L, surroundi.ng the enterincJ eoal eake and whose front encl, on the oven sicle, f:i.ts aga:inst tl-lc door framc of the coking chainber.
DE 28 21 169 describes a sealing frame which surrounds the oven opening and the entering compressed eoal eake and whieh, from a posi-tion nex-t to the ramming mould, can be placed in front of -the head of the coal eake to be eharged by means of a swinging boom. The swinging boom, on the o-ther hand, is arranged on a carriage travelling parallel to the oven axis so that it can be driven up to the oven opening. This known frame does not bridge the complete distance between the coking chamber and the ramming mould. Ra-ther, sealing on the side of -the ramming mould is aehieved by means of elas-tic sealing elements arranged on the sealing frame and lying direetly adjaeent -the entering eoal eakes.
I-t has been shown, in praetiee, -that these sealing elements, lying directly adjacent the eoal eake, have important disadvantages and lead to shut downs, in the first place because of the relative mo-tion between the coal cake and the sealing elements, and also because of the high opera-ting temperature to :, :

which ~hey are subjected due -to their posi-tion immediately be:~ore the openecl coking chamber ar-d which lead to elTIbrittlement of the sea1ing elements.
Ano-ther disadvantage of the sealing elements which fit by friction against the coal cake :Ls tha-t, when the coal cake gets s-tuc]c ancl there:Eorc can vn1y be charged partially, the re~iaining cake cannot be ~isposed of, i.e. cannot be returned to the ramming installation. When moving the coal cake back, against the direct:ion oE charging ~or which the frict:ion seal is designed, the result is an accumulat:ion of coal on the friction seal s:ince the coal cake :Ls de:Eormed by getting s-tuck in the coking chamber and does not form an exact square block anymore.
From -the point o:E view of construction, this known arrangement is very expensive. Over and above -tha-t, the arrangement of the sealing frame, which is swung back and retracted next to the ramming mould, leads to important space problems since in this area, on both sides oE the ramming mould, other elemen-ts are also provided such as -the mobile front door of the ramming mould, the charging stand s-top, the movable lifting device for the coking chamber door as well as the door frame cleaning device.
Therefore in DE 29 43 319, it was already addition-ally suggested to arrange the sealing frame immediately in front of the ramming mould door, in which case a s-ta-tionary frame is attached before the ramming mould while the actual sealing frame can be swung forwards and downwards by means of a parallel mechanism. Apart from the fact that also here sealing occurs directly on the en-tering coal cake, the passage for the operator, the distance between ' : .

the anchor supports of -the coking chamber and the ramming, chargi.ng and pusher machine, the so-called RCP mach:ine, are g:reatly reduced by -the stationary part of the arrangement. ~n order to prevent harrn to the opera-ting personnel during the operation of the RCP machine, a sufficiently wide passage, however, has to be ensured and in addition has to be pro-tected by a railinc~. On the o-ther hand, the total dlstance between the coking chamber and the ramming mould, :i.e. -the d:istance the coal cake has to travel wh:ile free standing should be kep-t as small as possible.
An object o:E the present invention is to provide a simple, practical arrangement to prevent the escape of gases duriny -the charging oE coal cakes into hor:izontal coking chambers, which avoids the above disadvantages.
With an arrangement o:E the type mentioned above, this problem can be solved by moving the side walls of the tunnel into the side walls of the ramming mould which on the oven side are designed as hollow walls, forming the tunnel bottom Erom the travelling ramming bottom and providing the tunnel cover with tele-scoping design and guides for the sliding side walls, in which case a levelling device which smoothens the surface of -the coal cake, with a disposal device for -the scraped off coal, is arranged on the stationary part of the tunnel cover.
Suitably, grippers, e.g. spring loaded friction contact members, are provided between the side walls of the tunnel and -the telescoping tunnel cover to move the -telescoping part in and out together with the side walls of the tunnel, so that a separate drive for the tunnel cover is unnecessary.

~03'~9'~
'l'he side wa~LI.s oF the tunne:L can be coupled clireclly with the travellincJ ramming bottom or -the ramming bottom drive so that also here a separate drive is not needed.
To the exten-t -that a ramming bottoln support is present, which is moved ou-t be~ore the coal cake is charged and which rests on a bracket in the oven chamber, the side walls are advan-tageously moved out when coupled with -the ramming bottorn support. This arrangement has -the advantage tha-t the side walls o:E
the tunnel and w:ith tllese the tunnel cover are already moved out and flt against the door frame of the cokirlg chamber before -the coal cake itself is charged. In this way the gases which already form when -the coal cake gets close to the hot coking chamber, are saEely disposed of, also helped by the chimney ef~ect which is setting in.
., I'he disposal o~ the gases can be carried out in known manner via a gas outlet, arranged in the cover of the coking chamber, and a gas collecting pipe, installed above the colce oven battery, as par-t of a gas cleaning installation. If the drawn off gases are burned in a gas combustion carrier travelling on -the coke oven ba-ttery or by passing same into an adjacen-t occupied coking chamber, the tunnel which surrounds the entering coal cake has, apart from preventing emission, the further advantage that air is not sucked along in uncontrolled condition wi-th the gases through the opened coking chamber, which can greatly influence the ignition characteristics of the gases and prevent an optimal combustion of the gases. By sealing off the entering coal cake, -the quantity of supplied combustion air can be adjusted specifically in accordance with the actual requirement.

3'7~..q3~7 In the case of the arrangement acco.rdiny to the inventioll, no frlction seals which fi.t again.st the enter:ing coal cake itself are requi.re~. ~rlle seali.ng on the sides is obta:ined here by Inear-ls o:E scaling s-trips arranged inside the side walls o:E the rammi.ng rnould and which ~it agains-t the -tunnel side walls The ~ownwar~ sealing is provid~ b~ ~he :ramm:ing bo-t-tom. On the surface of -the cake, -the seal:iny is obtained through -the coal bead formed by the coal which is scraped off by the levell:ing device.
E'o:r sealiny against -the door frame of -the cok:ing chamber, spring loaded cutting edges are` suitably provided which can also consist of cutting edge segmen-ts which, if necessary, can adapt -to the unevenness of -the door Erame.
In a moving-in position, neither the space between the coking chamber and the RCP machine nor -the space beside the RCP machine is adversely affected in any way by the arrangement according to the invention.
In the joined together position the telescoping -tunnel cover projects over the passage for the opera-tor, in front of -the ramming mould, however, depending on the heigh-t of the cake, a-t a heigh-t of 4 - 6 m, so that there is no adverse effect here either.
A static tube is provided on the tunnel cover to control -the charging operation which, under the influence of the pressure exerted by the accumula-ting coal, s-tops the charging operation in the case of blockage of the coal cake to be charged.

An arrangemen-t to prevent the escape oE gases duriny the charglng of a coal cake 15, produced in a ramming lnstallation 1 outside the eo]cing chamber 20 and standing on the travelling ramming bottom 14 of the ramming mould, eonsists of a tunnel 3 whieh bridges the distanee between coking ehamber 20 and RCP
machine 1 and which completely surrounds the entering coal cake 15.
To assist in the expelling of the gas exhaust from colcing ehamber 20 itselE, the gases retained in -tunnel 3 can be disposed of via a separate gas exhaust S which can be coupled to the tunnel via a closeable connection 25 and which, as in the example shown in Figs. 1 and 2, can be coupled via connee-tions 6 to a stationary gas eollecting pipe 7, the so-called gas off-take main, installed above the coke oven battery. Instead of stationary connee-tions 6 above every coking chamber 20, a travelling gas conneetion 19 can, however, also be provided, as shown in E'ig. 3. However, it might also be suitable ~7--:: .. . .

not to vent the gases clrawn orr ~rom tunrlel 3 together w:Lth lhe gases drawn o.EE frorn thc coking chamber 20 via tllc gas o:Efta]ce main 7, ~ut to ~:ispose of -them in a separate combus~ion chamber provided on the RCP machirle 1.
Tunnel 3 consists of the movable tunnel cover 9, side walls 10 and rarnrning bottom 14 portions, which in the moving-out state form a unlt, more specifically a tunnel.
For the operation oE -the RCP machine 1, tunnel 3 has to be moved back sufficiently Ear so -that a sufficiently wide passage between the anchor supports ~G of the colce ovcn hattery and the ~CP machirlc 1. i8 provided ~or ~he safe-ty of -the operating personnel.
Mo.reover, in the case of the arranyement according to the invention, the side walls 10 of the tunnel 3 can be rnoved in-to the side walls 4 of the ramming mould which in this area are constructed as hollow walls.
The -tunnel cover ~ is telescoping and, in the moving-in situa-tion above the ramming mould door 21, is a-t a height of about 4 to 6 m above the passage provided for the operator 23. The movable ramming mould door 21, the charging stand stop 22 as well as the movable door li:Et off device and door Erame cleaning device for the coke chamber door are not adversely aEfected in any way (Fig. 4).
The side walls 10 of the tunnel 3, are coupled with the ramming bot-tom support 12 and can thus jointly be moved in and out wi-th the latter (Figs. 5, 6, 9 10).
In so far as no ramming bottom support 12 is provided, the side walls 10 of the -tunnel 3 can also be coupled, e. g. via driving rollers 13 (Figs. 12, 13), to the travelling ran-lming bottom 14.

3~7~3~7 The telescopillg tunnel cover 9 is of U-shape construction It consists of a narrow stationary part 32 and a wldcr telescrop.ing par-t 31. The resulting lateral slot on both side.s serves as a guide for the movable side walls 10 of tunnel 3.
When moving out, the side walls 10 of tunnel 3 slide out together wi-th -the -telescoping part 31 of tunnel cover 9 by means of grippers 16 arranged in the slots 29. In -the embodi.rnent illustrated in Fig. 14, the grippers 1~ are designed as spring loaded friction elements. If the tunnel cover 9 fi-ts against -the door frame 2, the side walls 10, overcoming the frictional forces of the gr:ippers 16, move on up -to a s-top 27 arranged at the front end of the tunnel cover 9 so as to ensure tha-t the tunnel cover 9 seals with sufficient tension against door frame 2.
The side walls 10 of tunnel 3 are moved in the side walls 4 of -the ramming mould by rneans of rails mounted rollers and are guided by means of sliding guides 30. The small slot between -the side walls 10 of tunnel 3 and the side walls 4 of the ramming mould is sealed with adjustable strlps~ The sealing of the tunnel 3 against the door frame 2 of the coking chamber 20 as well as oE the side walls 10 against the ramming bottom 14 is carried out by means of spring loaded cu-tting edges 11 which are divided into segmen-ts 1.7.
The surface of the entering coal cake 15 is smoothened out by means of a levelling device 8 placed on the tunnel cover 9. The sealing on the -top side of the cake is obtained by the coal bead 15 which is formed during the process. Excess, scraped o:Ef coal is disposed of via a pipe 28.

In the case of a coal cake 15, wh:ich is stuck and can no more be charged, the charging operation is :intcrrupted by Lhe pres~sure resulting rrorn the coal whicll accumulates in the tunnel 3 and which acts on a sta-tic tube 24.
To charge ca rammed coal cake 15, a side wall 4 of the ramming mould mus-t be moved by a few millime-ters so as to release the coal cake 15. The side wal:L 10 of the tunnel 3, arranged in the movable side wall ~ o:E
the ramming mould, thus ends up in front of the slot 29 o.E the appropriately matched tunnel cover 9. On tlle side of the sLde wall 4 of the rarnming mould, mounted firmly on the RCP machine 1, -the upper part of the correspondlng side wall 10 of the tunnel 3 is engaged permanently by means of a guide nose 33 in the slot 29 of the tunnel cover 9.

An arrangemen-t to prevent the escape oE gases duriny the charglng of a coal cake 15, produced in a ramming lnstallation 1 outside the eo]cing chamber 20 and standing on the travelling ramming bottom 14 of the ramming mould, eonsists of a tunnel 3 whieh bridges the distanee between coking ehamber 20 and RCP
machine 1 and which completely surrounds the entering coal cake 15.
To assist in the expelling of the gas exhaust from colcing ehamber 20 itselE, the gases retained in -tunnel 3 can be disposed of via a separate gas exhaust S which can be coupled to the tunnel via a closeable connection 25 and which, as in the example shown in Figs. 1 and 2, can be coupled via connee-tions 6 to a stationary gas eollecting pipe 7, the so-called gas off-take main, installed above the coke oven battery. Instead of stationary connee-tions 6 above every coking chamber 20, a travelling gas conneetion 19 can, however, also be provided, as shown in E'ig. 3. However, it might also be suitable ~7--:: .. . .

not to vent the gases clrawn orr ~rom tunrlel 3 together w:Lth lhe gases drawn o.EE frorn thc coking chamber 20 via tllc gas o:Efta]ce main 7, ~ut to ~:ispose of -them in a separate combus~ion chamber provided on the RCP machirle 1.
Tunnel 3 consists of the movable tunnel cover 9, side walls 10 and rarnrning bottom 14 portions, which in the moving-out state form a unlt, more specifically a tunnel.
For the operation oE -the RCP machine 1, tunnel 3 has to be moved back sufficiently Ear so -that a sufficiently wide passage between the anchor supports ~G of the colce ovcn hattery and the ~CP machirlc 1. i8 provided ~or ~he safe-ty of -the operating personnel.
Mo.reover, in the case of the arranyement according to the invention, the side walls 10 of the tunnel 3 can be rnoved in-to the side walls 4 of the ramming mould which in this area are constructed as hollow walls.
The -tunnel cover ~ is telescoping and, in the moving-in situa-tion above the ramming mould door 21, is a-t a height of about 4 to 6 m above the passage provided for the operator 23. The movable ramming mould door 21, the charging stand stop 22 as well as the movable door li:Et off device and door Erame cleaning device for the coke chamber door are not adversely aEfected in any way (Fig. 4).
The side walls 10 of the tunnel 3, are coupled with the ramming bot-tom support 12 and can thus jointly be moved in and out wi-th the latter (Figs. 5, 6, 9 10).
In so far as no ramming bottom support 12 is provided, the side walls 10 of the -tunnel 3 can also be coupled, e. g. via driving rollers 13 (Figs. 12, 13), to the travelling ran-lming bottom 14.

3~7~3~7 The telescopillg tunnel cover 9 is of U-shape construction It consists of a narrow stationary part 32 and a wldcr telescrop.ing par-t 31. The resulting lateral slot on both side.s serves as a guide for the movable side walls 10 of tunnel 3.
When moving out, the side walls 10 of tunnel 3 slide out together wi-th -the -telescoping part 31 of tunnel cover 9 by means of grippers 16 arranged in the slots 29. In -the embodi.rnent illustrated in Fig. 14, the grippers 1~ are designed as spring loaded friction elements. If the tunnel cover 9 fi-ts against -the door frame 2, the side walls 10, overcoming the frictional forces of the gr:ippers 16, move on up -to a s-top 27 arranged at the front end of the tunnel cover 9 so as to ensure tha-t the tunnel cover 9 seals with sufficient tension against door frame 2.
The side walls 10 of tunnel 3 are moved in the side walls 4 of -the ramming mould by rneans of rails mounted rollers and are guided by means of sliding guides 30. The small slot between -the side walls 10 of tunnel 3 and the side walls 4 of the ramming mould is sealed with adjustable strlps~ The sealing of the tunnel 3 against the door frame 2 of the coking chamber 20 as well as oE the side walls 10 against the ramming bottom 14 is carried out by means of spring loaded cu-tting edges 11 which are divided into segmen-ts 1.7.
The surface of the entering coal cake 15 is smoothened out by means of a levelling device 8 placed on the tunnel cover 9. The sealing on the -top side of the cake is obtained by the coal bead 15 which is formed during the process. Excess, scraped o:Ef coal is disposed of via a pipe 28.

In the case of a coal cake 15, wh:ich is stuck and can no more be charged, the charging operation is :intcrrupted by Lhe pres~sure resulting rrorn the coal whicll accumulates in the tunnel 3 and which acts on a sta-tic tube 24.
To charge ca rammed coal cake 15, a side wall 4 of the ramming mould mus-t be moved by a few millime-ters so as to release the coal cake 15. The side wal:L 10 of the tunnel 3, arranged in the movable side wall ~ o:E
the ramming mould, thus ends up in front of the slot 29 o.E the appropriately matched tunnel cover 9. On tlle side of the sLde wall 4 of the rarnming mould, mounted firmly on the RCP machine 1, -the upper part of the correspondlng side wall 10 of the tunnel 3 is engaged permanently by means of a guide nose 33 in the slot 29 of the tunnel cover 9.
