T0 all whom it mcy conc-6m:

v'Be it known that L'FREDERIO W. C

SCHN1EWIND,-a citizen of the United Statesf of America, residing' in the clty, county', and State of New York, have invented a' certain new and useful Improvement in Coke-Oven- Discharging Apparatus, of which the following is a true and exact description, refv erence being had to the accompanying drawings, which form a part thereof.

' The present invention relates toapparatus for removing coke from the retorts or ook# .ing chambers of coke oven structures, and4J for receiving and discharging` the coke-rei; moved from theretorts to a receiving sta- '5- tion, where the coke is discharged either. into cars for railway transportation or into "other storing devices. f

The object of-the present inventionis to;

provide apparatus so constructed and arranged that the"cke from each Vretort can be readily and easily. transferredV to ajsuitable cokev receiver without 'undue jarring of the 'coke andv in a gradual'manner so that .the coke will neither jam in the retorty being emptied or be broken up, thus avoiding inv to the oven Walls and unduecrumbling of the coke, with aL consequent material reduction in the amount of coke breeze o r.

The bottom wall of each retort is formed end of a retort, land -is preferably lined with- ;irebriclr C2 to shield it and the adjacent iioorbeams A2 from the heat of the glowing coke when the retort is being emptied. The doors or' bottom, walls B are normally held in 'place by bolts or rackbars B4L operated bypinions B5 and engaging ears formed on stiffening yokes B6 secured to the members B2.

The understiucture A4 1s provided at i different levels with vrails D', E, and F',l on

which run the movable lids or coke Acover carriagesl) A and D B, and coke receiverv carriage E, and bottom door lift carriage F respectively.r Thecoke receiver carriage E vcomprises wheels E2 running on the rails E journaled in boxes Ev3 on which rest the end .beams E4 supporting the body E5 of the /carriage E. The wheels E2 are driven through gears E5 upon .cross shafts E8 which are vin turn drlvenrfrom the sha-ft E5 ofthemotor E13 'secured to the under side of the carriage bottom, the driving connection being formed of pairs of worm wheels E1o and gear wheel E11 inclosed in Vcasing E12. On the body .portion E5 is mounted the coke receiving platform proper G. The

platform Gr` is hinge connected to the platform E5 .at both-side edges to tilt relative thereto about Vone or, the other. of two axes located "one above each fail E.V This arrangement permits lcoke to be discharged from the receiver into cars located at either side of the carriage on-tracks H as shown in Fig; 3. The-hinge connections may be formed by pairs of bearings E14 formed on the -body E5, lv'each supporting a shaft or pintle E15 which is engaged by open ended bearing' members G secured to the under side of the platform G at itsopposite side edges. f Ears G11 are provided at-the side edges ofthe platform G, those at one edge or ythe other being engaged by suitable hoistking mechanism located at the end ofthe batteryto tilttheplatform about the pintles E15 at the opposite edge of the platform when it 1s desired to discharge the coke into the ,Coke

'receiving car or other receptacle located at one side or the other of the track rails H,

Y to receive the upper flanged edges of a pair of beams`G2,'as shown clearly in Fig. 2. At each -end of the *platform G is located an inclined and preferably removable end portion G5, which comprises inclined beams G7 supported at their outer ends on saddle members GD resting on the transverse I-beams JGS, and

having their inner ends directly supported\ by the body of the platform G. On -the rails or beams G6 are secured platform bars G5, like those secured' on. the beams G2. The outer ends of the beams G are faced by end members G1".

lVith the constriftio'iiirshpwii vit will be observed that abrokencr injured platform bar .G3 may be readily removed by sliding out the other bars G2 at one side of it which engage the same pair of beams G2 or G7. Preferably to facilitate the removal of the bars G3 the end portions G5 are secured to the body portion of the platform by readily detachable 4.connect-ions,A not shown. The carriage E'propervm'ay be protected from ,Water employed in quenching by a floor or covering between theA platform E and the bars G7 if thought necessary.

' vThe mechanismfor dropping and raising vmountedal vertically movable hoisting shaft F5, having its lower 4end threaded and carrying at its upper end a` head F'7 adapted to engage the. door; The heads FG of the two hoisting devices shown are connected by bars F7 which prevent rotation ofthe shafts F5. l/Vithin casing F2 is located a nut for the corresponding shaft F 5, the nut having'y i a thrust bearing F10. YVithin each casing also is located a worm gear meshing with the teeth formed on the nut FK The worms F 11 ai'e carried by the shaft F12 which may be geared to,.or, as shown, may be the shaft of motor F5. f

In the construction shown in Figs. 1 and 'EZ the carriages E and F are entirely independent. As it is .desirable however that each door B be dropped to a definite level,

viz: that on whichthe upper edge of the `door is flush with the upper ends of the inclined platformV portions G5, an arrangement maybe employed with advantage in which the door is dropped down on to the platform E. Such an arrangement is shown `1n Fig. 4, where the beamsE4 of the carriage ,Ehre extended to form supports on whichr the doorl B may be dropped by the hoisting device FW As it is desirable that the carriages E and F shouldk move together during certain stages of the discharging o eration,'an arrangement'may be employe` for detachably coupling the Atwoearriages to-v gether. In the arrangement .for this purose shown in Fiffg'f the carria e E -is`ro- P s P Y i vided'with downwardlyxtending arms or brackets E16, .which of course should be so n arrangedas to clear the hoisting mechanism, and the carriage F 1s .rovided with similar upwardly lextending rackets F13, which, when the two carriages are in the position in'which they should be coupled together,` are located immediately ybeneath the brackets E1 so that the two carriagesmay be secured together by thefpin E11 passing through suitable apertures formed in the brackets E1 and F13.

' The means for covering the coke on the platform.- Gr and thereby -protecting the under oven structure proper from the heat of the coke comprise, one or more lids or covers in the form of carriages ruiming on the track rails D.k In -the\ arrangement shown in the drawings there are two of these covers D A and D B employed in discharging each. retort. Each of these carnages, which may both be identical in construction, has wheels D2 running 'on Vthe track rails D. .The body ofthe carriage is provided at its under side with a series of I beams running parallel to the rails D.

The I beams D11. support plates D3, which may be similar to the platform bars G3, thus forming the lid or cover proper for the glowing coke. To Aprotect the carriages proper against the heat conducted from the faces D3, which are preferably made of castl iron, a suitable non-conductin material like mineral wool may be packed a ove the faces of the bars`D3.. -To prevent the coke from spilling off the sides of the receiver` and also to protect-the adjacent portions of the Asup- I porting structure A1 each side edgefnf each I cover is providedA withan apron or depend-4 ing shield. This apron or shield is formed bv" metal ieces D which are rovided at their upper ends with grooves receiving the base of the side I beams DH. For the purpose of connecting carriages A D B to the carriage E, the body portion of the latter may be provided with posts E13 arranged in the same vertical planes withv posts orV brackets D3 depending from the sides of the cover carriages. By this arrangement the 'corresponding posts D and E13 may. be4

readily connected iis-by ia'ipin D1.1 or the like.. In discharging each retort A,the carthe drawings, the carriages D-A' and D B are provided at their ends with depending guides D1. Adjacent guides D7 of the two carriages employed thusunite to form a chute through which the coke passes. With the apparatus operating as shown in Fig. 1, 2 1t is of course necessary to hold the left hand cover carriage D A stationary in' order to prevent its being displaced by the thrust ,ofy

the coke as the carriage E moves to the left.

The carriage-mayof course be held stationvary in any lsuitable manner as by locking it to the track rails D .or to the overhead ovenbeams A3.l It is also desirable in somecases to regulatethemovement of thecoke on to .the receiving platform. This may be obtainedl by'providing an arrangement whereby the guides D7, may serve inv eect. as

clamping jaws, 'and' be moved relatively to each other in order to clamp and release the coke cake. For the purpose of holdingl the carriages D A and D B stationary and of adjusting them as desired, as `well as for the purpose of obtaining 'the clamping ac-4 tion referred to between the guides D", the

arrangement shown particularly in Figs. 5

and 6 may be employed, although it will be understood that the mechanism shown in these figures is merely. illustrative of one of many arrangements which may be employed. In the construction shown best in Figs.

5f and .6, each cover carriage D A or D ,B

is provided at itslside between the wheels' D2 `-with spur gears D15 which mesh rack bars D3 secured to the overhead oven. beams yA3, and extending parallel tothe rails D.

Each spur gear D13 has a shaft carrying at its inner end a clutch member D-9 which cooperates with a clutch lmember D10' carried by a shaft D11. The shaft D11 is, by motor lio D13, driven through the spiral gear D13 carried 'by the shaft D11 on a worm wheel on the shaftof'the motor.

Then the clutch members D9 and D10 are released, theV spur gear D15v is free to rotate lizo .I

when the carriageD A or -DB is moved on the track D and does not interfere with the movement of the carriage. Vhen, however,

`the clutch members p? and D1 are locked together the carriage is effectively locked.

to the stationary oven structure through the spiral and 4worm gear connections to .the motor D13. Such movements of the carriagev ments by the coke receiver carriage.

as is necessary in adjusting the position of the carriage and particularly for obtaining the clamping action between the guides D7 of adjacent' cover carriages may be obtained by operating motors D13. It will of course be understood that the motors D13-may be used to propel the carriages D A and D B along the entire length of the track formed by rails D if desired, but this is not the primary purpose of the motors in the particular construction illustrated, since, the cover carriages may be given large move- The clutch members D9 and Dlo vmay be controlled in any suitable manner, for instance, they. may unite With suitable electrical connections to form an electro magnetic clutch.

It will be understood that the rails D', E and F yall extend at least to the end 'of the battery to Which they belong, and that the rails D extend beyond the battery., and that a suitable quenching apparatus is located beyond `the end of'the battery for spraying `Water on the coke and cooling it before discharging it from the coke receiver into the cars or other lcoke receptacles.

Each retort may be discharged asl follows The cover carriages D, the coke .receiver y carriage E, and the door opera-ting carriage lEand the carriage F are then moved slow y and gradually to the lft to allow' the coke to descend on tothe cokeplatform GrA of the carriage E. On -account ofthe gradual up- Ward inclinationkof the advancing end G6 of `the receiver platform, the coke cake may be transferred With 'little or no crumbling from the top of door B to the body of the platform Gr'. Further `advancing movement of `the platform G on account of the greater friction on the horizontal portion of the platform causes the lower end of the cake to break up butin relatively large pieces.

The descent of the coke and thereby the manner in.\vhich it is broken up may be regulated as before described by the adjustable, clamping action exerted on the coked rake by the guides D7. To increase the friction between the guides and the coke the forium' may be roughened as indicated at -`pled to the carriage E.

D X in Fig. 4:. When the coke from `the retort being discharged has all been placed upon the coke receiving platform the carriage E is moved to theleft.- as is also the ycarriage F, which has preferably been cou' The carriages E and F arethen uncoupled and the clutches are operated to release cover carriages D, and the left hand cover carriage D is moved to the left to get it outofthe road; at the same time the right hand cover carriage D is coupled to the carriage E as by the coupling connection D6. After the door B and carriage F are disengaged from the carriage E the latter is moved to the right to the quenching station located at the end of the battery,`and the hoisting apparatus on the carriage F returns the door to the normal position-Where it is secured by the-bolts B4. If, as may be desirable to obtain the necessary clearance, the tracks D do not. extend beyond the end of the battery, the right hand cover D B Will be disengaged from the carriage E when `the former arrives at the end of the battery, and the coke carriage will then be moved on to the quenching station, where after the coke is quenched it is discharged either into the right hand car or the left hand car as .desired by the chains H of the stationary hoisting mechanism, not

shown, which engages the ears G11 at the left or right hand edgevrespectively of the platform Gr.

Aprons or guides H2 are provided for insuring that .the coke reaches the cars. Vhen the guides H2 are suitably perforated rthey serve as sieves permitting the coke -breeze to .drop through them. It will of course be understood that Where there are more than one battery or unitary coke oven structures'in a single plant, the hoisting and receiver tracks may be .extended to permit the'receiver and hoist to operate under all the batteries.y The tracks for the covers may also 'be so extended though in case of such extension some modification would be necessary as otherwise the cover tracks would interfere with the operation of discharging betweenv the batteries. It will be observed that With the apparatus disclosed the varihighly advantageous in its'general operation.y All of the devices employed are located on one side beneath the furnace where their operation can be observed and conl View of the present state of the arl of controlling motors from a distance. Because of these conditions the labor cost of dis- 'charging the furnaces is reduced to a minimum, the operator or operators work under favorable conditions and are notexposed to oppressive temperatures and the various devices are properly timed.
