To all whom it may concern:

Be it known that I, Srnrnnn Nnwcoiunn \VELLiNcroN, a subject of the King of Great Britain and Ireland. residing at 3!) Mincing Lane, London, E. (,1, England, have invented. certain new nd useful Improvements Relating to Apparatus for Discharging and Quenchin Coke, of which the following is a. specification.

This invention relates to apparatus for discharging and quenching high or low temperturc coke or the like from vertical retor s, and is more especially applicable for the discharge of the residue of distillation at comparatively low temperatures. The invention has for its object to effect the discharge of the coke from vertical retorts so as to avoid waste, to improve the coke, and also to effect the quenching of the coke in a simple and effective manner without con tai't of the coke with the water used. and generally to provide an apparatus simple in construction and cfl'cctive in operation.

According to the invention I provide receptacles for the reception of the whole charge from the retorts, and I mount the receptacles upon a carriage torun on rails mounted immediately beneath the retort set ting, so that thus -the receptacles mounted upon the carriage can he brought beneath the respective retorts of the battery or setting in succession. I provide gear for the purpose of lowering the charge into the receptacles, the gear being niounted advantageously upon a separate carriage and mounted to run beneath the carriage upon which the receptacles are mounted. According to the invention also the gear comprises one Or more ram adapted from beneath to pass through the receptacle 51* receptacles to take the weight of the bottom 'cover plate or door and to lower the bottom cover plate or door withthe charge into the receptacle; the gear advantageously comprises an electro-motor and controller with a clutch conveniently provided. by which the motor may be employed for driving the carriage upon which the gear is mounted to run on rails. or in the alternative for lifting or lowering the rams, while the gear also comprises means manually operated by .wluoh fi e ad u men of the p ion i oi -side and beneath ram'or rams and carriage may he climbed, or if necessary also of the carriage upon which the receptacles are mounted.

The invention comprises the constructional features which are hereinafter described in an apparatus provided according to the invention. 4

1n the accompanying drawings is illustrated, by way of example, an apparatus according to the invention.

Figure 1 is a side elevation partly in section of a modified construction of the apparatus.

Fig. 2 is an end elevation of the apparatus shown in Fig. 1.

Fig. 3 is a plan view of the gearing w l -2 ating the I'lillli to an enlarged smile.

Fig. 4 is a sectional elevation of thr ge'iring corresponding to Fig. 3 taken on lin: of spindle j.

Fig. 5 is a front elevation of the illustrated in Figs. 3 and 4.

In carrying the invention into effect as illustrated in Figs. 1 and 2 in the construction of u quenching machine provided ac cording to the invention. I provide two receptacles d mounted upon a carriage frame 8 in SllGlLPOSlliOIi that two alternate vertical retorts of a battery may be discharged multaneously and I provide each receptacle. with a sliding cover plate 1 provided on each the plate with toothed racks adapted to mesh with pinions 2 mounted each upon a spindle 3 carried immediately beneath or at the side of the outwardly flaring upper end of each receptacle. A chain wheel and chain 4 (Fig. 2) serve to cause the rotation of the spindle 3 and to cause the cover plate 1 to slide to or fro for closing or opening the top of each rece tacle. Upon the carriage frame 6 a tan 5 is mounted adapted to contain the water 'for quenchingthe coke in the respective recep- The lower ends of the receptacles tacles. pass 'into the tank so that at their lower ends the receptacles are completely surrounded hy the water contained inthe tzmk. Holes 6 are formed in the top of the tank 5 in a, position corresponding to the respec: tive receptacles and of a larger diameter than that of the receptacles so that thus 0:! the ater be ng pray fr m he upper end of the receptacles on to the outer surface thereof the water returns to the tank.

I mount a pump and motor equipment, n a position above the tank as illustrated in Figs. 1 and :2 with the suction pipe 7 ex tending to near the bottom of the tank and with its upper end connected to the pinup S which is operated hythe motor 9. 121m pump outlet discharges into the water pipe 9 by which water is supplied to the spray pipes 10 which completely surround the re spective, receptacles, the spray pi ms 10 heing provided with orifices throng iout their length by which water is directed inwardly toward the outer surface of the receptacle. A platform 11 serves for access by the attendant to the up ier part of the receptacles.

A central overl low outlet pipe 9 may he, provided in the tank in the position indicated in Fig. 1 and partitions 12' may extend into the tank short of the hottom as a means for preventing the water being spilled on a too sudden movement of the quenching machine or on a too sudden ai'i'estiiient of this movement. I

The motor equipment and gear for causing the movement of the ipienchingr machine upon the rails upon whici. it. is mounted is advantageously provided in the front part of the carriage frame as illustrated in Fig. 1, the motor hcing indicated by 1?). the ontroller by 13'. and the gear he H hy means of which movement is imparted to the axle 15. A contact arm 16 is provided in position beneath the carriage frame r hy means of which current may he passed to the. motor from conductors t? of a three phase circuit mounted near the side wall of the well in which the discharging machine is mounted as illustrated in 'l ig. 2.

Each of the receptacles at its hasc and on each side is provided with a sliding plate 18 and these sliding plates are provided with toothed racks engaging with segments 19, One. of the segments is mounted upon a spindle 2U transversely disposed arrow the carriage frame while an operating itiver 21 is mounted upon the outwardly protruding extremity of the spindle 2t) and this operating lever 21 is extended at one side for the iurposo of connection with the cori'cspoiidmg toothed segment 19 hy means of a link 22, while at The other side of the spindle 20 opposite to thatv upon which the operating lever 21 is mounted a short downwardly e'iz tending tlllll is provided corresponding to the downwardly extending part of the lever 21 for eonnection'with a second link 22 mount,- ed upon the other side of the carriage frame. A link 23 is provided on each side to connect. the respective sets of segments together of each of the receptacles so that the respective sliding latest 18 of each receptacle may be operat by the single operating hand lever 21. The, normal position of the sliding plates 18 is indicated in Fig. l and these, protrude within the receptacle and form ledges on each side for carrying the hot tom door .24 upon which the charge is supported.

The inwardly protruding edges of the sliding plates 18 are formed with curved downwardly Having flanges :25 which serve to lll'lllg the rain 12h on its upward movement into precise coincidence with the. center of the receptacle.

It will thus he understood that the hottom doors of the rctoi'ts to he discharged are retained with the charge in the receptacles. For this purpose the carriage lil'illlit' is extended at one end in order that two spare doors it may he transversely mounted in position thereon coiicsl'ionding to the posi tion of the retorts and these alter the dis charge of the rctoi'ts may immediately he lifted into position to ('lOsc them so that they may he immediately i'c-charged.

(tripping arms :27 may he mounted hencath the carriage t'i'anie w to prevent liahility ot the carriage frame hein g upset on the spare hottoni doors 2'! heing lifted off the ironic. These gripping arms 27 engage the slides of the respectiie rails upon which the carriage frame 1* i mounted to run in such manner that they do not normally contact with the rails hut permit oi freedom of movon'icnt.

in carrying the invention into etlcct in the construction of the discharging: machine as illustrated, l proiidc a liasc'platc 23% upon the carriage l'ranic f il'o hosscs it! suitably provided for the reception f hall hcarings up n which worm wheels may rotate the norm wheels lining prmidcd with an in ternal thread ciirii-spondine to the external thread provided upon the rain spindles 1 i provide a longitudinal shall I: with worms in dctcl'inincd position for engagement with the worm wheels rclcrred to, so that thus the thr aded spindles 5/ of the rains may he moved upwardly or downwardly on the rotation of thc longitudinal shall it in one direction or the other. "lhe worm wheel may he suitahly incascd. as may also the worm. For the purpose of preventing the rotation of the respective threaded rain spindles r/ l mount on each of their lower extremities an arm 3U which is provided with lateral lugs 31 at the end to engage the i'cspcctiic lateral edges of the corresponding arm near its boss 32 by which it is mounted at the end f the threaded spindle. Any other means for the same purposiu may however, he [)lUVltlttl.

The motor 33 is ad 'antageously mounted in direct line with the longitudinal shaft 7:. and one end of the motor spindle j dis posed close to the end of the longitudinal shaft h, and the respective members 34, 35 of a clutch are mount ed on the adjacent ends of the motor spindle and longitudinal shaft, so that thus the longitudinal shaft in may e caused to rotate witlr'the motor spindle j or be disconnected therefrom according to the position of the movable member 35 of the clutch.

Upon the end of the longitudinal shaft h adjacent; or upon the boss of the clutch member 34 carried thereby, a toothed pinion 36 is mounted to engage with :1 corresponding toothed wheel not shown mounted upon a spindle 38 through which movement is imparted to a circuit breaker 39 disposed in an adjacent position so that on the rotation of the longitudinal shaft h on the operation of the motor 33 in one direction or the other, that is to say, in the direction necessary for the upward or downward movement of the ram 26.excessive movenu-nt of the ram may be prevented. The sign 40 indicates a brake of any usual construction, preferably a mag nctic brake, whereby movement. of the spindle of the motor may be checked or stopped. A magnetic brake 40 may also he provided to arrest the movement of the motor 33 and motor spindle.

Adjacent the clutch 34, 35 and immediately beneath the extremity of the motor spindle j gear is prmided by which movement may be imparted to a second longitudinal shaft I through which the rail wheels are rotated for the movement of the carriage frame f from place to place. This gear may consist of two toothed wheels 41, 4:]. the larger 41 of which may be disposed so as to he engaged by the toothed pinion 35 integrally rovided on the movable member 35 of the c utch, while the second toothed wheel 42 may be integrally provided with the toothed wheel 1 1,and this second toothed wheel 42 may engage with a toothed wheel 43 mounted at the extremity of the second longitudinal shaft 1. The second longitudinal shaft l is advantageously mounted beneath the carriage frame 7 and is adapted to cause the movement of one of the axles 44 by which the carriage frame f is supported. For this purpose a wormniay be mounted upon the extremity of the second longitudinal shaft Z to engage with the corresponding worm wheel mounted upon the axle 44. t

The respectiye adjacent ends of the shaft h and spindle j are carried within suitable' hearings upon a support 53 over which a cover 54 is applied and bolted.

I provide the hand lever 46 for operating the clutch 34,. 35 upon a spindle 48 disposed -m a convenient position accessible to the attendant who may stand upon a platform 49. disposed lower than the level of the top of the carriage iramef a: corresponding hole tht mechanism is rendered operable by the hand wheel 52. For this purpose a gear wheel 55 is mounted upon the end of the motor spindle j in a position adjacent to the clutch 34, 35 before referred to, and this gear wheel 55 engages with a corresponding pinion mounted upon a spindle 57 disposed parallel with the motor spindle j. The spindle 57 is at one end carried upon the support 53 and at the other upon the supporting frame 58. This latter serves also to support the motor spindle and to receive one side of the casing or guard 59, which at the other sidcis mounted upon the support 53. At the end of the spindle 57 the hand wheel 52 is mounted in a position accessible to the attendant so that on the clutch 51 intended for permitting operation by hand being caused to engage, the brake magnet is lifted to permit of easy operation of the gear by hand. By such means it will be understood that the hand operated mechanism is avilable for adjusting the position of the carriage frame f in relation to the receptacles d mounted on the quenching machine as well as the position of the rams 26.

A contactlcvcr 60 may be provided to extend above the level of the carriage frame and-pivotally mounted in position thereon in such manner that it may be -displaced on the contact lever 16 of the quenching machine being moved in position over it. For this purpose an arm on the contact lever extends below its pivoting point and is engaged on each side by means of spiral springs which tend to maintain it in its upright central position. The contact arm 60 is advantageously provided-with three contacts where, as is preferred, a three phase electric circuit is used.

It will be understood that the quenching machine is adapted'to run upon rails over a pit within which the discharging mechanism is adapted to run upon rails of a narrower gage than that upon .which the quenching machine runs, the pit being provided centrally sufficiently deep topermit of the complete retraction of the ram spindles. Such an arrangement of the quenching and discharging machines is indicated in Figs. 1 and 2. i

The operation may be readily understood III from the foregoing. I bring one of the carriage frames, preferably frame e, into position over the pit, either before or after I have cooled or quenched the coke in the receptacles. I then bring the lower frame f into position and cause the rams to rise and thus push the coke out at. the top.

The receptacles may he discharged in any conrenien' manner. I prefer to discharge them by lifting the coke after it has been cooled so that it may he deflected on to a. conveycr and then passed away for loading into trucks or harges. the coke being thus hroken into large pieces and without C6D siderahle waste.

It will thus he seen that on the two carriage frames movahle aith respect to each other. I have embodied all the parts necessary for eti'ccting rapid and safe discharge of coke. The lower t'ramc may serve the upper frame 0 or several of them, in any posilionand at any time desired. ()nc upper frame may serve several ovens.

1t will he noted that in the operation of my device. the machine as a whole ishrought. to approximate position with respect to the ovens by means of motor 2%, "1y means of motor 13, the carriage t'rame c is brought to position withrespe t to alternate retorts of a coke oven battery. These retorts are dis-- charged into receptacles n which are closed. The. hot coke is cooled therein hy spray pipes, 10. After cooling it. is discharged preferably at the upper end upon a con veyer. ltleantilme the machine may have heen permitted Ito receive and cool coke from other retorts ot' the hattery.
