W hen the cokiug operation has been coinpleted the whole interior of the oven and the entire mass of the coke block are very hot. Before however the eolie block can be hanv tiled it. is necessary to quench it and reduce its temperature sulliciently to permit handling. This may be done to best advantage by spraying the coke bloei; with water.

ln the structure shown in Figs. l and 2 hook shaped supports 3 are provided on each side of the mouth of the coke oren and these-supports arc'designed to receive the end of a pipe #L which may be made up of a suitable number of tees 1 joined by nipples 5 and terminating at the ends in longer pipe sections sufliciently extensive to rest in the hooks 3. To each tee there is secured a nozzle (i and the structure Vis such that the pipe Acarries a series `of nozzles extending across the opening to the coke 'oven and directed toward the interior of said oven. One end of the. pipe beyond the corresponding hook 3 's rovided with a cap 7. other end ot the pipe beyond the corresponding hook 3 there is provided a union 8 receivingr one end of a hose 9 the other end of `which ma) be connected to a valve l() on the upper-end of a branch pipe 11 rising from a main l2 buried a suitable distance "iu the round and extending along the front of the' ank of ovens.

Fast to the pipe 4 near one end thereof is an arm 13. The free end or' the arm 13 may be provided with an eye. for the reception of the hooked end 14 of an operating rod 15 of sufhcient length so thatthe handle end may be so distant fromthe mouth of the oven that au operator is out of the danger zone caused by the outrush of steam or het gases from the mouth of the oven.

When it is desirable to quench the coke after the burninfT of the charge in the oven has -been complited, 'the closure for the I mouth of the oven is removed and the pipe 4 is hung on the hooks 3 with the nozzles (l directed into the mouth of the-oven and the hose 9 is attached t o the valve 1 0 which latter may then be opened so that there is prt duced a flow of water through the hose 9 into the pipe 4 and from thence in the form of jets from the nozzles into the oven above the coke block 2, and assuming a proper elevation of the discharge end of the nozzles 6 and a sutlicient pressure of water, the jets may reach to the farther end of the coke block. By changing the elevation of the discharge ends of4 the nozzles by rockingr the pipe 4 about its longitudinal axis on the At the,

the other as the operator may desire, the large quantity of water available quickly quenching the coke to a suitable temperature for subsequent handling, the steam generated escaping through the open end or ends of the oven. It will be understood of course,that the battery of nozzles 6 and the pipe -t may be provided at each end of the oven, the arrangement then being a duplicate of'the arrangement shown in Figs. 1 and soon as a coke block iu an oven has been suitably quenched the hose 9 may be disconnected from the valve 1l) after the latter has been closed and the pipe t may therbe carried to the next oven to be treatet. and the process of quenching may then be repeated, the structure being' light enough to be handled by one operator so that much tiine is saved without any increase in the ruimher of operators needed.

' Where tracks-alongY the line of ovens are available, then the battery of nozzles 6 may be mounted on a suitable truck 16 ass-howl; in Figs. 3 and 4 or 17 as shown in Figs. 5 and 6. v

Referrin first to the structure shown in Figs. 3 an 1l the-truck 16 is a small easily handled structure but little longer than the Width of the mouth of an oven and this truck is mounted upon wheels 18 adapted to the track indicated at 19, such tracks being commonly provided for apparatus used in connection with the handling of the coke.

'The platform of the truck may overhang),r toward the oven to bring' the structures carried thereby into operative relation to the oven, the truck being adapted to the tracks already available. At the side of the truck' adjacent to the oven there is mounted a frame 20 which may for convenience of construction be made up of pipesY and pipe littings, but of course any other suitable frame structure may be employed. One long side of the frame 20, the side adjacent to the body of the truck. and therefore in operation the lower side is secured to the truck by bearing blocks 20 in which the said lower side of the frame may turn so that the upper long side of the frame may be swung in an arc about. the longitudinal axis of the lower side of the frame thus permitting the movement of the upper long side of the frame to and from the mouth of an oven. The upper long side 'of the frame is in the form of a pipe 21 so supported in the side members of the frame as to be capable of independent rotative movement about its longitudinal axis. The pipe 21 includes a tee .Q best shown in Fig. 7 and this tee is coupled b v a nipple .23 to another tee 24 introduced into the pipe 4 made up of the nipples ;i and tees 4 with the latter carnvirngy nozzles (i similar to the battery of nozzles shown in the structure of Figs. 1 and 2 except that the terminal nozzles of the battery ot' nozzles are eomieeted lo the pipe l by elbows 5 beyond which the pipe l does not extend.

ln the structure shown in Fig. 'i' the nipple 23 iseonnected to 'the pipe ilmidway the length of the latter while the ends of the pipe i are supported and braced by straps l 26. having eye `ends embracing the corresponding portions of the pipe 4 and of the pipe 21 so that, tlie' battery of nozzles will 'participate in any rotative movement ot' the 'pipe Q1 ni the frame 20, the nozzles moving in an are about the longitudinal axis of the pipe 21 :is a center. Y

Fast to the pipe 21 is one end of au arni 27 and to the other end of this arm there is connected a linl; .28 extending and connected to a hand lever 2l) i'nonnted on the. truelc I of which the. frame may its .supports 20' to :in iT desired position and near the side thereof remote from the ovens, the lever 29 being of :in ordinary type capable of being locked in adjusted liiosiiion.

lhe frame 20 is shown as provided with a central cross bar 30 which may also be made of pipe and this bar is coin-noted by a linlt or rod lll to a manipulating lever 32 by means be rocked about there locked, thus {,ierinitting the movement of the pipe. 21; toward or from the nioutli of the oven as the operator rocking of the freine, E20 toward the oven being sutlieiently extensive to permit the introduction of the nozzles (5 to aconsdviable distance into the mouth of the oven if such be desired.

Fast to ilie eross har or pi )e iO'is a shield 33 having the edge. remote roiii the har 30 .secured to the lower member of the traine 2() by brace bars 34 so thatwlien the traine 20 is in operative relation to the mouth of the oven with 'the nozzles'tl introduced thereinto the shield 33 will extend across the lower portion of the i'noutli of the oven with the lower edge of the Shield below the. lower edge of the mouth of the oven and the body of the shield slopingr in an upward direction away from the mouth of the oven toward the cross har 3P.

Piroted at the lower edge to the eros-s har 30 is another shield 235 eonstitutin a eontinuation of the .shield 33 and this shield 35 is connected by a rod or link 3G to a manipulating lever 37 by means of which the shield 35 may he looked in adjusted positions.

Mounted on the truck 11" is a valve 38 liaving a hose 9 attached thereto for coupling-r I of the valves l0 e the valve 3S to any one posed along the line of ovens :it the upper ends of the branch pipe 11 coming from llnl main 1 2. The valv 38 is eonnvfrted by a flexible pipe o." hose 39 lo one end ot the ipe 21, the other eud thereof being clos-od.

eientli lou;r to iin-lode more than one oven at the end connected b The battery'of nozzles 6 of each frameQO i is so located as to^be introducible into the end. or mouth of a corresponding oven, but these ovens wild be separated by an intervening oven to which the structure is inactive whenoperating upon the separated ovens. The rest of the structure is similar -to that of Figs. 3 and 4 except that the valve 38 to which the hose 9 connects is included in a pipe44 on the floor of the truck and this pipe 44 is in turn eonnectedto an intermediate point oi another .pipe 45 extending from one end to the other of the truck and respective flexible pipes S9 to. the outer ends of the pipes :'21,

In the pipe 45 between che point o connection therewith to the pipe 44and the end 'of the ipe 45 'connected by a fieirible pi e 39 to t e pipe 21 at one end of the trucs, there is introduced a. valve 46. Also 'the le- Vver 32 for controlling the position of 'the frame is connected to a rock shaft 47 which in turn is connected at one end by a rod or `link 31 to the corresponding Irarne 2O so that the two frames may be moved simultaneously b means of the one controlling lever 32. Trie shaft 47 may be made hollow `and another rock shaft 48 extends 'therethrough and beyond the ends thereof, this last' named shaftbeing connected at one end .to thelever 3'( for operating the shield 35 While the other end of the shaft 48 is connected by a. link or rod 36 to the corresponding shield at the other end of the truck. By

this means a single operator may spray two ovens simultaneously, thus correspondingly facilitatin the operation. If at any time it be advisab e ,to spray but one oven at a time with the structure of Figs. 5 and 6, then the ialve 46 may be closed' and Water admitted to the pipe 44 throu h the valve 38 will. pass to but one battery o nozzles 6.

During the first part of the operation of ruenching the coke, it is not necessaryY that tie o erator should watch the proce and there ore the screen may be in its most elevated position to protect the operator from the ou'trushing hot gases ,or steam.

` As the operation progresses the screen or 5f? be repeated.

Since the Mitchell type of coke oven admits of the rapid expulsion of the coke, many ovens ma be discharged one after the other by a single nusliing apparatus. in

5 a comparatively brief period of time, but

evase? unless the quenching of the coke to a temperature at which the coke may be handled .rceps pace with the possible rapidity oi operation of the usher, the advantage of the oven for facilitating rapidity of operation is lost. But the present invention provides a means for quenching the coke with such rapidity that a`serics of ovens ma)y be prepared for the act-ion of the pushing apparatus as rapidl)7 as th, latter can operate to expel the coke, and this preparation not only requires a minimum oi time but a n1i"-inium of labor since a single operator may cause the quenching of the ovens as or more rapidly than the mechanism used for discharging the coke from the oven 'can be made to operate.
