To all whom t may concern.'

Be it known that I, Louis ViLrU'r'rE, a citizen of the United States, and resident of New Rochelle, in the county Ot Vestchester and State of New York, have invented certain new and useful Improvements in Regenerative Coke-Ovens, of which the tollowing is a specification.

My present invention relates to the type of regenerative coke ovens having horizontal coking chambers separated by intervening heating walls formed each, with a series of vertical flues connected in pairs at their upper ends; and thegeneral object of my invention is to provide an improved arrangement of the regenerators and regenerator connections for supplying preheated air alternately to the two lues of each connected pair.

2O The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding oi the invention and the advantageous features possessed by it, reference should be had to the accompanying drawings and descriptive matter, in which I have illustrated and described preferred embodiments of my invention.

i Of the drawings:

Figure l is an elevation in section on the broken line 1-1 of Fig. 5.

Fig. 2 is a partial plan in section on the line 22 of Fig. l. Fig. 3 is an elevation in section on the broken line 3-3 of Fig. l.

Fig. 4; is a partial elevation in section on the line 4-4 of Fig. l.

Fig. 5 is a partial plan in section on the line of Fig. l; andV Fig. 6 is a view taken similarto Fig. 5 illustrating a modiied construction.

In the drawings, and referring first to the construction shown in Figs. le inclusive, the coke oven shown, comprises a plurality of horizontally elongated coking chambers A., separated by heating walls, each of which is divided into a series of lues B and l). As shown in'Fig. 3, each flue B is separated from the adjacent flue l) at its right by a wall B10 whichterminates at its upper end below the tops of the flues B and L, so that the pair ot' lines B and o between which each wall B10 is located, are connected at their upper ends. Each pair of lues B, Z), thus connected at their upper ends, is separated trom adjacent pairs of ues B, b by a wall B11.

Each heating wall is carriedby a supporting or pillar wall C. Below the coking chambers and between the pillar walls C, are series or row's oit regenerator chambers E and c. The chambers Il or e in each row are separated from one another by division walls B10 or (210 lying` in the same plane as 65 the flue division walls B10 and B11. The regenerator chambers E alternate with the regenerator chambers e in a direction 'transverse to the lengths of the heating walls. The row of regenerator chambers E between one adjacent pair of pillar walls C are connected to the lues B in the two heating walls above the pillar walls C by channels or ports II. Similarly the row of regenerator chambers e between an adjacent pair of pillar walls C are connected by ports 7L to the fiues 2') in the two heating walls above these pillar walls. It will be understood that each of the regenerator chambers E and e is connected to a flue B or b lying between the division walls B10 and B11 which are immediately above the side walls B10 or 61 of the corresponding regenerator spaces E or e.

As shown in the drawings, there are a series orf regenerator chambers ea at one end of the battery connected by ports 7L to the tlues Y) in the one adjacent heating wall; and at the other end of the battery there are a series of regenerator spaces EA connected by ports II to the lines B in the one adjacent heating wall. The regenerator chambers EA and ca diter from the chambers E and e in that there are but half as many of these in a row, and in that each of the regenerator chambers EA and @a is conveniently made twice as wide, measured parallel to the length of the oven chambers and heating walls, as a regenerator chamber E or e. It will be understood, of course, that the checker brick (not shown) is piled in the usual manner in the different regenerator chambers E and e.

Beneath each row of regenerator spaces E and EA are located channels or conduits F and G. Eachv channel F preferably receives an iron air supply pipe FA formed with discharge oriiices which register with the brickwork ports F, opening into the lower end of the corresponding row of re- `channel G which serves as a waste heat channel is connected to each of the regenerator spaces above it by a corresponding port G. All of the waste heat channels are connected, each through a corresponding valve casing D10 to a tunnel D running transversely to the length of the coking` chambers at one side ot the battery, and as shown the outer end ot each air pipe FA is connected to the corresponding valve casing' D10 through a. port F2 in the latter. A valve member D11 is mounted in each valve czsing D10 between the port F2 and the corresponding channel G. These valve members D11 areconnected to the usual rc- Versing' mechanism (not shown) and serve, when in their closed positions, to cut off communication between the waste heatchannels G and the tunnel D. Advantageously the valve members D11 are provided with portions D12 closing the corresponding ports F2 when the valve members D11 are moved to permit comxnuiiication between the channels nl and the tunnel D. Similarly, beneath each row oi regenerator chambers c and ea is located a pair of channels f and g which connect by corresponding` ports and g to the regenerator chambers above them. The channels g are connectedby valve casings d10 to a tunnel cl, running lengthwise of the battery at the opposite side ol the latter from the tunnel D. The channels f preferablyv receive iron air'supply pipes fa, similar to the air pipes FA and connected to the valve connections f 1 as the air pipes FA are connected to the valve casings D10; and in each valve casing (ZW is mounted a Valve member D"1 similar in construction and operation to the valve member D11 in each Valve casing` D10. D13 and Z13 represent draft regulating` dampers in the valve casinfgfs D1 and Z111 respectively.

rldrantageously the channels (l and g are' tapered in the direction oi' their lengths to insure an approximately uniform How velocity ot' the waste gases through the channels G andv y at" all points along; the lengths of the channels. The ports G and g aswell as the discharge orifices in the iron air pipes FA and fa. are proportioned to insure the desired distribution of low among' theV different heatingn fines and regenerator spaces.

Combustible gras is supplied, when re` quired, to the lower end ot each i'iue B through a port I1 and the usual removable gas nozzle therein fromv a corresponding gas gun or gas supply passage lf', there bei'n'g'one of these supply channels l in the upperportion ofeach pillar' wall'C. Similarrly each'lue 7;' receives'comlmstib'le gas at the properV times through a corresponding port i' and the usual removable gas nozzle froma gas gunJ or chan-nelz'f 'located inthe upper' portion of the corresponding` pillar wall C.

ln the arrangement shown in Figs. l and 5 all the gas guns l and t" are connected through corresponding valved connections, one of which, marked i2, is shown in Fig. 3, to a gas supply main In located at one side of the battery. ln the construction partially shown in Fig 6, the gas guns l all project at one side ot the battery and are connected to a gas main at that side of the battery, while the gas guns z" project from the opposite side oi the battery and are connected to a gas main lying at that (opposite) side of the battery. rllhe `different arrangements oi th'egas guns shown in Figs. 5 and 6,result in certain difference in' the arrangement of ports l and in construetions shown in Figs. 5 and 6. TheseA arrangements are clearly shown, and will be readily understood by those skilled in the art, from the drawings and need not be described in further detail.

lAir and gas are suppliedto the lower ends ot allot the Various [lues B during one period or stage of operation, while during the following stage of operation air and combustible gas are supplied to the lower ends of all the fines The vahfesDm and d10, the Valves controlling the supply of gas to the gas guns l and t, and the valves (not shown) controlling communication between the tunnels D and (Z and air blower or fan, and a stack or other suction creating device being' manipulated in the usual way to bring;V about a reversal ot flow at the usual intervals of, say one-halt hour each.

In the condition of the apparatus shown in the drawings air and gas are beingsupplied to the lower ends of the fines B. The tunnel D is then disconnected' from the stack, and receives air from ay fan or blower, While the tunnelti is disconnected from the source of air supply and is connectedfto astack or other draft suction creating device. The Valves D11 in the Valve casings D10 are set to close communication between the tunnel D and the waste heat channels G and to permit air to pass 'fromV tunnel D through ports F2 into the air' supply pipes FA; In this condition ot the apparatus the valve members D11 in the Valve casings 0310 are in the position in which they open communication between the waste heat channels g and tunnel (Z, and in'which they close communication between tunnel d' and the air pipes fa. Thel air thus permitted to pass into the air supply pipes FA is discharged from the latterthro'ughthe ports F into the lower ends of the various regenerator chambers E and EA.l The air passes upward through the regenerator chambers E and 'EA and is thereby heated. The heated air passes out of the chambers E and ea into the fines B-through the ports H. The preheated' air loro thus entering the lower ends of the liue B ignites the combustible gas then being supplied to the lower ends of the iue B through the ports I from the gas guns I which then receive their gas from the corresponding external gas supply main. In this condition of operation the gas guns z" are disconnected from the gas supply main. The burning ases ignited at the lower ends of the flue pass upward through the latter, thence over the tops of the iue walls B10 into the flues b, following downward through the latter and out through the ports. 7L. The hot products of combustion leaving the lines through the ports 71 enter the regenerator chambers e and @a and after imparting a large portion of their heat to the checker brick in those regenerator chambers issue from the latter. through the ports g into the channels g, through which they pass to the valve casing d10 and through the latter into the tunnel d.

It will be apparent from the previous description of the apparatus, as well as from the arrows on Figs. 5 and 6 that each row of regenerator chambers E between an adjacent pair of pillar walls supplies preheated air to the lues B in the two heating walls at each side of the row of regenerators, while each row of regenerators e receive the products of combustion from the flues Z9 of the two heating walls at the opposite sides of the row of regenerators e. lmien the direction of the flow is reversed, air is supplied from the tunnelV d to the air supply pipes fa, passes from the latter to the regenerator chambers c and ca, is pre-heated therein, and passes out of these chambers through the ports it into the iues b, while combustible gas is then supplied to the lower ends of the iues b by the gas guns i.. The burning gases ignited at the lower ends of the flues b then pass upward through the latter, downward through the lues B, and from the latter through the Y ort's H to the regenerator chambers and A and out of the latter through the ports G, channels G and valves D10 into the tunnel D.

Since each of the flues B and b is connected to but one regenerator chamber, it is only necessary to insure the proper supply of air to each on regenerator chamber, and the proper supply of gas to the lower end of the flue to which each on regenerator chamber is connected to insure the proper distribution of flow among all the iues and regenerator chambers. The supply of combustible gas may be regulated in the usual manner by the use of interchangable nozzles of proper size, and the supply of air to the reGenerators is primarily regulated by the sizes of the discharge orifices in the iron air supply pipes FA and fa. When a change in the distribution of air is desired these iron air supply pipes may be with-7 drawn and the discharge orifices restricted orv enlarged as required. To avoid undesirable pressure diiierences in the various flues and passages,`the olf-take channels Gr and g are preferably tapered, as previously described, and the ports G and g should be properly proportioned. In addition to the simplicity and positive control, of the dis tribution of air and gases, obtained with the present invention it is to be observed that the oven and regenerator construction is simple and compact, and that the oven brickwork may be constructed in accordance with accepted and tested principles of design and construction.

While in accordance with the provisions of the statutes I have illustrated and described the best forms of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed without departing from the spirit of my invention as set forth in the appended claims, and that certain features of the invention may sometimes be used to advantage without a corresponding use of other features.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. In a coke oven comprising horizontal coking chambers, intervening heating walls divided into vertical fines connected in pairs at their upper ends and provision for periodically supplying gas to the lower end of one flue of each pair, and at alternate periods to the lower ends of the other flues, the improvement which consists in a separate regenerator chamber connected to the lower end of each flue.
