` coking chambers 1 ing channels 12 (Figs. 3 aiid 5). The other chamber 27 of each regenerator 20 is connected at the bottom by means of a channel 31 (Fig. 6) containing a cut-ofi valve 32, with a flue 33v leading to a reversing valve 34 (Fig. 1) located at the left hand side of the oven adjacent to one of its ends.

Inan analogous manner the chamber 28 of cach let hand regenerator 21 is connected at the bottom by a channelv 35 with one oi the vertical collecting channels 13, While the other regenerator chamber E29 communicates at its lower end by means of a channel 37 controlled by a valve 36, with a flue 38 likewise leading to the reversing valve 34. This reversing valve is secured to a shaft 39 which by means of a lever 4() (Fig. 2) can be turned from the position indicated in Fig. 1 to the reversing position, in the well-l nown manner. According the valve 34 occupies one or the other position, .it either connects the flue ivith an air inlet 41 and the tine withv a smoke line 42 leading to the stack', or the flue 'lfwith the smoke flue 42 and the fluo 38 with vthe air inlet 41. To regulate the total amount of air required by the bench vof ovens, I provide a valve 5G secured to ascrew spindle 49 and `located above the air inlet 41, said valve being adpistable vert1- cally by means of a hand lever 51 secured to the spindle, to vary the effective cross sectio'n of the air inlet 41.

The coking chambers are'filled with coal through top opening normally closed by covers or 'plugs 43, while the colte is removed. throughopenings at the bottom, normally closed by plates 44. The gas produced in the passes through the conduits 45 (Fig. 6) at the left of the ovens to the condenser 46. At the right hand of the ovens there are conduits 53, which may be .blosed by means of removable covers 52 and which serve for the escape of the gases at the termination of the colring operation and at thetirne of filling the oven chambers 1.' The ovens rest upon pillars 4i' (Fig. 1) be tween which is left a space 48 (Fig. (i) for the passage of the cars used to carry away the coke. The partitions 2 are supported by beams 19 resting on the foundation.

The operation of the oven is as follows: W hen the coking chambers 1 are heated from the riv lit-hand side ofthe oven, as indicated in tie drawings by arrows, the gas valves 7 (Fig. 6) are open and the gas valves 10 closed, the reversing valve 34 being in theposition indicated in Fig. 1. ln this case gas enters each of the heating (lues 8 through the corresponding burner 4 (Fig. 4) While the air for supporting combustion is eonveyed to both sets of heating flues 3 of each .partition 2 from the common collecting channel 12 through'the branch channels '1 4'.

The combustion ga.. travel through theA "i heating lues 3 but once, from right. to le tion.

and in so doing give olf most of their heat to the coking chambers 1. The still considerable heat then remaining in the combustion gases is then carried away with them through the branch channels 15 tothe respective collecting channels 13 and thence through the short channels 35 into the corresponding upright regeneratorsr 21 arranged immediately adjacent to the individual coking chambers 1. lt will be 'seen that the heating gases do not have' to pass through .any long connecting channels on their way from the heating flues to the ie'generators, so that l avoid losses o'f heat which would result from the employment of such long channels. Thus that portion of the heat contained in the heating gases which has not been absorbed by the coking chambers will be delivered almost in full to the regenerators and by them transferred again to the incomingr air intended to support oombus tion, after the direction` of` the gas and air currents has been reversed;

ln each regenerator the combustion gases travel upward in the inner chamber 28 and downward in the outer chamber Q9. By subdividing each regenerator into two chambers I provide for the combustion gases a long path of comparatively small cross-sec- In passing through the regenerator chambers 28, v29, the combustion gases 've olf the heat contained in them to the chec erwork of the regenerators, with the exception of a remnant such as is required to insure a proper draft in the stack. The waste gases traveling through the regenerators 21 do not heat the coking chambers 1, but simply main tain the temperature prevailing within the oven. In order not to interfere with a uni form operation of the oven, the hot waste gases enter at the bottom of each of the inner regenerator chambers 28, that is the chambers nearest to the cokng chambers, so that duringY their upward travel in said chambers, they will lose heat., corresponding to the upward decrease of heat `wit-hin the oven. The waste gases, after passing through the outer regencrator chamber 29 from top to bottoni, reach the flue 38 throu h the channel 37 and finally travel through t 1e smoke lue 42 leading to the stack.

At the same time, the air for supporting combustion enters throughthe inlet 41 into the flue 33 and then passes through the channels 31 into the regenerators 20. Through each of these regenerutors the air passes in a direction opposite to that of the passage of the waste gases through said regenerator during the operation period immediately preceding. During its travel through the rcgenerators, the air absorbs the heat stored therein. The highly heated air then passes from each regenerator 2U to the corresponding collecting channel 12 through the channel 30.

thus the Lesina? Reversai oi the operation is eti-ected by throwing the valve 34 into its other position and by closing the gas valves 7 and opening the gas valves l0. This will cause the heating gases to travel through the ues in the direction opposite to that indicated by the arrows in Fig. a, While the regenerators 21 serve to preh-eat the air intended to support combustion and the regenerators 20 are heated by the Waste gases.

ery important advantages secured by certain features in the relative arrangement of the coling chambers. 'the heating fines, and the regenerators. Thus, the regenerators are loc-ated at the end of the oven (adjacent to the short sides oi the reotangnlar ooking chambers) While the (horizontal) heating fines are disposed between the colring chambers (adjacent to the lone" sides of said chambers). I ain thus enabled to place the colina-chambers very close together, since the' partitions between theni contain only the heating iiue Another advantage resu ts from the fact that regenerators and heating,` fines are not adjacent to each other, but located in different walls; y walls et the heating iiues are not likely to crack, but even if they should, the combustion gases escaping through suoli Cracks would have to travel a. comparatively ong distance in order to reach the. regenen ators. The heating Walls or partitions are noty attested by the periodical heating and cooling ot' the regenerators. and tlias the eating of the colting chambers is very uniform. In my improved oven, each of the heating Walls has its own set ot regenerators and it is therefore a very simple matter to regulate the heating;T action of each Wall individually, or even to stop the heat- .ing action entirely for any one ot the' heating Walis, which is a great convenience in making repairs. in order that individual regenerators may be provided for each heating Wall, the upright arrangement has been adopted for such regenerators-- The regencrators 20, 2l may be Inodied by omitting the partitions 2a, 25, that in this case each regenerator wiil have a single chamber. The collecting channels l2, 13

would then be connected with the upper ends of the regene ators 20, nels 3i. would 2l, While the Chain be connected with the f nerators, as described. f on7 tte air for supporting coin-bastion would pass through the regeneratoi but @noe from the bottoi l the tot), and after reversal the Water would pass through the regenerators but once, from top to bottoni. This inodiiication and others may be niade Without departingtroni the nature of nay invention as defined in the appcnded claims.
