To all whomit may concern ")0 it known that I, Josnrrr BECKER, a

citizen of the United States, residing in littsbii' i, in the county or Allegheny and tf'tate o Pennsylvania, have lnventeo. a

new and useful Improvement in Coke-Oven ilmoke-liischurging Means, of which the ibllorsim: is a specification.

This invention relates in general to coking plants and has for its essential obiect thcprovision of an eiilcient means tor taking care of the smoke incidental to the charging of a heated coking oven which permits the smoke oiitake to continue until leveling operation has been eii'ected, therebi' insuring proper discharge or smoke "from a coke even during the entire period or charging and preparing the charge within the oven for coking, with the result that trrip iiing oi smoke within the oven is eliminated I A further highly important ob1ect oi the i is the provision of means tor (llS- the smoke either into a smoke the usual gas collecting main, desired, the valuable by-products main or n so that. 1

carried along" with the gas laden smoke may he recwrered with the gas evolved in the coking of the charges within the several hambers oi" the plant and discharged into collecting main.

Serial No. 330,980.

convenience the present description will be confined to this use of the invention; features 01" construction are however readily susceptible of other valuable applications and consequently it is manifest that the scope of the invention is by no means confined to the specific use and the specific embodiment herein described.

By referring to the drawings, there is indicated at 11 a fragmentary section taken longitudinally through an oven or coking chamber of a coke oven battery, or plant, of the by-product type. It will be under stood that the coke oven battery may be of the usual construction, embodying generally a plurality of coking chambers arranged side by side and extending transversely of the battery and provided with the usual alternating heating walls having plane tlues intermediate adjacent coking chambers. Each coking chamber or oveh is provided with'a set of charging holes 12 and also in the present instance, with a set of smoke outlets 13, the several smoke outlets being each independent of the charging holes. The several charging holes 12 oi each oven chamber are arranged at intervals therealong. as clearly shown in Fig. 1, and the independent smoke outlets 18 are disposed in alternation with the charging holes. According to this arrangement, a smoke outlet is located between each pair oi adjacent charging holes, with the result that smoke may escape from the oven chamber durins. charging and until the leveling operation has been completed, through outwhich are intermediate the several mounds of coal deposited in the oven by the oharg ig ap iiiratus. thereby eliminating trapping oi? smoke in the oven and insuring complete oil-take ot the smoke. during the charging and leveling interval. The charging holes 12 and the smoke outlets 13 respectively extend through the top 14 of the coking chamber or oven and may each be provided with suitable closures, not shown, but of a construction well known in the art, for closing the top of the oven during the coking operation. It will be understood that the closures of the several charging: holes and smoke outlets are removed. during the charging operation. At one side of the coke oven battery, preferably the pusher side, there is provided a collecting main 15, the latter communicating with ascension pipes 16 extending i'ipwardly from gas outlets 17 formed in the top let ot the respective ovens or chambers 11. The gases evolved from the coking oi? the charge of coal in each oven or chamber pass np\.vardly through the ascension pipe and thence into the collecting main 15, through which such gases pass to the by-product recovery up paratus.

The charging of the individual coking chambers or ovens of a coke oven battery is, in the present instance, effected by means of a lorry car adapted. to run on tracks 17 extending lengthwise across the top of the battery or series of ovens, whereby the lor y car may be moved into charging position with respect to any of the chambers or ovens to be charged. In its construction, the lorry car embodies a suitable suppor ing frame work for the several. instrumentalities mounted on the car, the entire frame and other mechanism being supported upon wheels 18 journaled in suitable bearings 19 supported by the bottom of the frame. The lorry car or truck, in the present instame, provided with four coal hoppers 19 of general funnel shape and supported by the framework in any suitable manner. The bottoms of the hoppers are located at spaced intervals and are adapted to be positioned directly over the tour charging holes 12, as shown more particularly in Fig. 1. Each hopper is normally closed at its bottom by a slide 20 beneath whh h is located a depend-- ing chute 21 provided with an encircling extensible sleeve 22 adapted to be projectezl into registry with an appropriate charging hole 12 of a coking chamber or oven 11. lVhenever a slide 20 is moved from closed position, the charge within the corresponding hopper is emptied through the chute 21 into a coking chamber 11. In order that the hoppers 19 of the lorr v car may be opened severally, an individual control is provided for the several slides 20 ot the spective hoppers. This indi idual control includes an operating lever 23 for each slide 20 and independently-operable gearing connections, indicated diagrammatically at 2st in Fig. 2, between the several operating levers 23 and their corresponding slides 20. If desired the levers 23, as well as the other control parts of the lorry car, may be grouped within the cab 25, in which the attendant in control of the car stands. The controlling lever 26 for the extension sleeves 22 of the several chutes 21 is also mounted in the cab 25 the motion of said lever is transmitted by means of appropriate gearing connections 27 between said lever and the several extension sleeves 22 for the purpose of elevating or lowering said sleeves in unison, it being understood that the operation of all the sleeves 22 is dependent upon the operation of the single slecve-controiiing lever 26 In addition to the gas collectinpmain 15, a smoke main 28 is mounted on suitable sup ports 29 along the side of the battery opposite to the collecting main 15. Preferably this smoke main extends clear along the battery of ovens and is provided with an inlet 30 opposite each coking chamber or oven 11. The construction of the sevv 'al inlets 30 is designed to close these inlets automatically, when not in use for permitting smoke to enter the main 2S, and will l e explained he 'naiter.

M unted on the lorry car or truck, pro erably extending laterally tliereer {O pip-e or line 31 which may sired, be n'ovided. with explosion caps respe tively located the opposite ends u: said pipe Ihese explosion caps are convt-znicntly constructed of hinge: ooors adapted normally to close the opposite onus of the smoke pipe but which readil open the accumulation oi? an undue r, in said pipe. I

In accordance with the present invention meats is provided for permittii ti snickel I i a coke oven or chum .r r, ii-

on to pass through ling in nuznl ,c with the s oi a chamber or oven and lead downwardly from the smoke pipe or tine 251.. The d or pipes o are, disposed in alternation with respect to the charg; ng devices or coal hog) )c rs. in Fig. l, to cooperate with the altecnaie smoke outlets .13 of an oven chamber and to permit the smoke which collects oetween the mounds of coal in the oven chamber to pass Ireely to the smoke pipe 9' from which it can be dis harged optionally into the sm ke main 28 or thecollectinn' main At their loner end the several branch pipes 3 are provided with encircling sleeves or extensible parts 2734 which are adapted to be lowered in unison into smoke conveying position with respect to the t-(nresi ionoin smoke outlets 13 of a coking chamber oven whenever said sleeves 34; are in rceistry with smoke outlets. For this nuriiose each sleeve 2% is pivotally connected: by means of vertical links 35, see Fig. 3, with arms fixed on a rock shaf 37, the hitter jourualed in suitable bearing 38 supported by the frame of the lorry car. Also, fixed on the shaft 3'? is a crank arm 39 pivotally connected at its upper end to link 4-0, the latter in turn being pivotally connected at its opposite end to an operating lever ll preferably located within the cab 25. With this construction the operation of the lever ll will rock the shaft 37 and through the connections 36, eiiect a lowering or elevating movement of the several sleeves 3 in unison. may be retained normally in elevated position by means of arms 42 also fixed on the shaft 37 but projecting oppositely from the arms 36 and provided adjacent their outer extremities with counter weights 43.

The smoke discharged through the smoke outlets 1.3 of coking chamber or oven 11 into the smoke pipe or flue 31 of the lorry car may. in accordance with the invention, be discharged either into the smoke main 28 or the collecting main 15, or into both of said mains simultaneously as desired. When sunoke is discharged into the collecting main 15, the latter not only functions as a smoke main for permitting oil-take oi the smoke, but also permits the smoke to pass, before its final discharge, through the usual byproduct recovery apparatus, where recovery may be had of valuable by-prodnets carried off with the smoke. In order to accomplish this highly desirable control of the discharge of the smoke, the smoke pipe or line 31 is provided preferably at its opposite ends with coupling elements re spectively adapted to connect the collecting main and the smoke main with said smoke pipe indepenuently oi each other. At its end adjacent the smoke main, the smoke pipe is provided with a branch pipe i l extendir therefrom in a horizontal plane and prov .ed with an outlet surrounded by a seat 4:6. Pivotally mounted at l? on the seal; i6 is a coupling member or pipe union 48 having a vertical passageway 1-9 adapted to communicate with the said outlet and a horizontal passageway 50 adapted to communicate with one of the inlets 30 of the smoke main. Each outlet 30 of the smoke main consists essentially of a short pipe section 51 projecting within and with out said main and provided with an inclined inner edge against which a pivoted closure is adapted normally to gravitate into position for closing the outlet of the smoke main. The closure 53 is pivoted at its upper end, as shown at 54, within the smoke main and is'shifted from its normally closed position, indicated by dotted lines in Fig. 4:, into an open position, indicated by full lines in said figure, by means of the following mechanism. Pivoted at its upper end, as shown at 55, beyond the outer edge 56 of the pipe section 51 is a ring 5'? provided with an inwardly projecting cam 58 adapted to engage the closure 53 and shift the latter into open position on movement of the ring 57 toward the outer edge 56 of. the pipe section 51. Normally the ring 57 will gravitate away from If desired the several sleeves 3i the edge 56, into the position shown in dotted lines in Fig. 4:, thereby permitting the closure 53 to gravitate into the closed position hereinbeiore described. The opening movement of the ring 57 is accomplished by the vertical edge 59 of the coupling member 18, which when the latter is lowered into coupled position with the smoke main, as indicated in full lines in Fig. l, will engage said ring to shift the same inwardly and open the closure Thus a positive and automatically operating means is provided for preventing escape of smoke through any of the outlets 30, when the latter are not in use.

The coupling member 4.8 is pivoted to the end of a link 60 extending to and pivoted at its opposite end to an operating lever 61, preferably located within the cab 25. If desired a crank arm 62 may be pivoted at 63 on the link 60. The crank arm 62- is pivoted at its opposite end at 64 and is provided with a counterweighted arm 65 for shifting the link 60 to normally throw the coupling member 48 into its inclined or inoperative position, as indicated by dotted lines in Figs. 1 and l. This construction insures movement of the coupling member into an inoperative position when the smoke discharging operation has been co npleted and prevents its striking the pipe sections 51. during the movement of the lorry car on its track.

At its opposite end the smoke pipe 31 isprovided with a coupling member adapted to make connection with the collecting main 15 in the event it is desired to discharge the smoke from the pipe 31 into said collecting main. The pipe 31.is provided with a short branch 66 on the outer end of which is pivoted the horizontal portion 6? or" a discharge pipe 68. Said pipe 68 is "further provided with avertical portion 69 the outer end of which is turned down, as at 70, so

that it may make proper connection with 1 an inlet 71 of the ascension pipe 16 of an oven. The inlet 71 of such ascension pipe may be normally closed by a pivoted cover 72. When it is desired to direct the smoke from the pipe 31 into the collecting main, the cover 72 of an ascension pipe adjacent which the lorry car is stationed, is opened and the pipe 68 is swung into position in which the turndown portion covers the inlet 71 of the ascension pipe. This operation of the pipe permits the smoke to pass into the collecting main and any by-prod ucts contained in the smoke will be recovered along with the gases discharged into said main from the other ovens for the battery.

Suitable valves, 73, '74-, are provided for shutting oil the coupling member 48 or the pipe 68 from the smoke pipe 31 whenever said member 48 or pipe 68 is not in use.
