"www m y1,000,981'. `1.\SRll'l`()lt'l` lili.' lll. llaa- Max Bnaoi, Springfield, Mass., assignor of onehalf to Charles ilenry 'l`eniiey, llart-ford, Conn. Filed May lf'i, 1908. Serial No. 433,180. To u-ZL whom it may concern.' .13e it known that I, Hamam Buaci, acitizen of the United States of America, re-i ,siding at Springfield, in the county off ,Hampden and State of li'iassaehnsetts, have'- pnvented new and useful Improvements in Gas-Retort Benches, of which the followingI lis a specification. l M invention relates to improvements in` beneies used in the distillation of illiiiiiinafing gas, in which I provide moans forl directing and controlling in a positive and certain manner the gas, carhoii inonoxid {(CO), which is generated below what is commonly known as the oxid flue and whichV grises into such flue, as said gas leaves them selves when remotely located relative to the openings at the top of the aforesaid flne aie old, but the application of s 'ncli plates directly to such openings for which they in reality forni slnitters is striictnrally as well yas functionally new and novel` The baflleplates could not be applied in this way, however, were it not for the presence of the aprons.- The aprons are provided wherever there are no other walls to separate the inouths of the passages leading from the top of the oxid flue and assist in foriniiig such passages, so that there is ai'iopportiiiiity for the baille-plates to be utilized to advantage in admitting the carbon monoxid to said passages. In a bench thus constructed the products of combustion. in the oxid flue are definitely directed or admitted to the several passages leading from said ilatter to pass upward to the chamber where the retorts are located, as hereinafter se i iforth. l lleretofore ninch difliciilty has been ex-i tperienced in maintaining an approxiinatelyi even heat throughout the entire areas of?! theretorts which coiitiiin the coal troni which the illniiiinatiiig gas is irodnced. owing to the fact that the distri intimi ofi the c alorific iiiedinin froni the niain or oxiil" flue is uneven; and-thc object. of my inven-i tron is to overcome this diflieiiltv bv providiiig a bench in which such disti-ibptioni |can be properly directed and regiiliited, tol Ithe end that an increased qnantitv of il-i `luniinating gas can be produced .from aa 'given aniount of' coal, and this with the con-.1 'snniption of less coke to snpplv the heat re-t uired for the distillation of 'the as fronii t ie coal. I attain this object by t ie ineansl illustrated in the accompanying drawings, in which- Figure'l is a vertieiil cross-section of so'.y inu'ch of a gas-retort bench as is reipiiredi to illustrate my invention which is eiubodiedl therein, auch view being taken on lilies l-#L 4looking in the. direction of the arrow, inf glfig. 2, and, 1 ig. 2, n longitudinal vertical ,eeetion on lines .2--.. looking` in the direel tiou of the arrow Fig. l.

Similar fignresl refer to siniilar parts,l throughout the several views. f

lutt inv invention is equally applicable to u tbeneh in which the i'etorfs lie horizontally l and the passages from the oxid flue are not l stepped.

(lenerally speakiiw this invention eonl sists of iiproii walls, hereinafter termed simply aprons, across the main or oxid flue between the branch passages leading from flue instead of being permitted to escape f`roni the flue in a more or less haphazard inanner.

ln the drawings a portion of a bench is shown in which appear a chamber 3 atthe top having therein a plurality of gas reltorts 4 inclined downward froml back to l front, a central vertical flue ."i which is the niain or oxid flue, a plurality of Y-sliapcd ',pnssages leading froin said flue info said chainber, euch of said Y-shaped passages i consisting of a vertical piiit or passage G and two lateral oblique branches or passages 7, side passages 8 for air, and pther side passages t) for the spent-gases, both sets of said l air and spenbgas passages and said passages 7 openingr at the top into the chaniber between I transverse vertical Valls or partitions .20 lwliieh assist in supporting said i'etorts and divide, all but the upper portion of` the chainber into flame passages that. are in the saine vertical planes with the Y passages. The aforesaid Y-slia icd passages are grouped together on diflerent levels in the usual ,mannen With the exception of the lower terminals 6 of said Y passages, the above mentioned members are old and well-known l as is also the slunting generator-apron wall .l lf) af the front. 'l`he passages ti are f'oinied by nieunsI of aprons ll which depend troni i the top of the, flue 5 to serve as front and rear walls for said passages except where. i the usual ninsonry of the bein-li answers for 2 this purpose.

l Arranged'directly under the a irons tl I und the passages (t, on supporting ledges or ,brackets l2 lwhich projectI into the flue Ii l from both sides, are, baflle-phites 13, there E being one such ilate generally for each of' 1 i .aid passages. 'lhe baille-plates` are adapted l l to be moved forward and backward on the brackets 12 so as to leave openings l-'l be Itween the biiflle-plates theinselvcsand be- |tween them and the sides of' theI passages said flue, and'of ha flle-plates'at the entrances g to such passages. Batlle-plates in themli both sides of the longitudinal center thereof.

:i air from the passages 8 mixes with the earj bon iiioiioxid and this mixture is lnirned in the spaces between said partitions to heat l, the retorts t and cause the gas in the coal il contained in said retorts to he liberated. t; The spent ases in the cluiiiiber 8 escape 2| therefrom tirough the passages ti.

j; three 6 for the escape, of the carbon monoxid from i the flue 5, such openinfrs being beneath said passages of course.

, y of anyl opening 14 the volume of carbon monoxid which is permitted to enter the,

iassafve above is accordinfflv varied and iti 1 l f b of gas to and through a chamber of small is in this way that I am able to completely control the supply of heat to the retort chamber. The baille-plates 13 at any level-j are shifted in the usual manner by means of a suitable implement introduced into the tlue 5 through a correspondinfv opening 15 in the rear wall 16 of said tue, after re-.l` moving a closure 17 from such opening. In practice, assuming that the baille-plates 13 have been pro erlay arranged to start with and that tieir positions will be chan ed from time to time as may be found expe( ient, the products of comnistion in tho flue 5 find their way into the chamber varying the size 3 through the openin s 14, the nissages G, and the passa es 7 wiicli brancli otl` from the latter an open at the top into said chamber, between the partitions Q0 therein,

In the chamber 3 between the partitions 20 I ain aware t at a gas retort bench luis separate supplementary er and the supplementary rs. I have found, however, from ed do not give the desired result for the,

reason that the retort chamber is necessarily arranged 'at an angle and there is a ditl'erenre in vaeuuiii between the lower and upper ends of the. retort chamber of one-half extending to the point of gicutest vaeuuni, i

and when thc volume of gas is not sullicicnt tu till all the individual coiuliiits such gas as [lows through these conduits will pass;

through those opening in the. retort cliaiuher at the lowest level. This results in creating a iartial vacuum in the supplemeiil tary gas c iainliers causing a down-tlow of f5 air from the. mixing chamber resulting in a mixture of gas and air in the supplementary gas chambers, which'mixture burns and produces an extremely high degree of heat i causing fusion of the structure. I am also aware that an ellort has been made to overcome this ditliculty by the omission of the supplementary gas chambers constructed as above described and providing for a tlow area from which the individual conduits extended to the retort chamber. Tithsuch construction, however, a similar difliculty arises because of the fact that a partial viiciiiiiii is produced as above described and a down-tlow of air throuf'h some of the conduits results because of` the difference in 'l vacuum between the lower portion of the retort chamber and a higher point, so that with such constructions it luis been found impossible to iiiaiiitiiin gas retort' benches ieriiianently as the mixture of gas and iiii in the siippleiiieiitaiy chamber, whether it i be one or more, results in the production of chamber through each conduit may be controlled without reference tothe lowthroiigh any other conduit.

I aiu able, therefore, with my construction, to so regulate the bench as to avoid the disastrous heating` which luis heretofore resulted and nin euabled to iiiaiiiifiictiire gas of a uniform quality at less expense than has been possible heretofore by the. old style of construction of gas retort bench.

It. will thus be clearly seen that. this invention enables me to direct in greater or less volume the heating medium from the main tlue to any particular part of thev chamber in which it is to be consumed, with the result that IV niniiitnin un even lient. luirii less coke, und obtain more illuminating yas.

'I'lic eonstluctioii und arrangement of the baille-plates are such that any oall of the passages ('i can lic closed thereby.

'l`herc is more or less ditl`erenec in tht` eoiistruction of benches, and it is to be uiiderstood that. I do not. confine my invention to the particular constructionherein shown and described, it being applicable and adaptable to all benches in which the same general characteristics are to be found, and tor this iciison I seek to claim said invention broadly.

What I claim as iny invention, and desire to secure by Letters latent, is-

1. In a device of the class described, the

y combination with a retort, of ii series of combustion chambers of approximately the.

same length extending across said retort at intervals having as inlets adjacent said retorts, separate adjustable dampers for said g inlets, means for adjusting said dampers, j and means for supplying air to said conil bastion chambers.

2. Inn a device of the class described, the

combination with a retort, of a series of coxny bastion chambers -of approximately the same, length extending across said retort at inter.

' vals havin gas inlets adjacent. said rctorts,

said inlets, means for adjusting said dampers, and means for supplying air to said combustion chambers, whereby the heat in the various combustion chambers may be controlled and rendered uniform and will he concentrated on said retort.

Il. In a device of the class described. the' combination with a series of elongated retorts, of a gas supply extending aloner said retorts, a wall of approximately uniform thickness se )arating said retorts from said gas supply iaving passages therein extending transversely of said retorts at intervals constituting combustion chamlwrs, a separate adjustable damper for the inlet to each of said passages whereby the combustion in said passages may be controlled and rendered uniform, means for operating said dampers, and means for supilying air to said combustion chambers, the llength of said passages heilig such as to bring thel point of iighest heat at said retorts whereby it will be absorbed.
