-JL 'a Pstenteel "i9 iii@ 26, 1909. Serial No. 489.132.

- eitizen ot' the llnited States, and resident of the borough ot Manhattan, in the eity und State oi' New "York, have invented a new and useful lniprtwenient in Retorts for the ).lanuineture of illuminating-Gas, of which the 'following is a speeifieation.

This` invention eonsists in Certain i1nprovenienteI in the' eonstruction,Y forni und :irrangenientl ot' the several parts ot' un nprip'lit ons retort used tor the manufacture of illuininniing gas 'from bituminousl coal, the retort being` oi' that elass in which there is :i e-onlinuou` earbonizat'ion ina eoinpletely Jr'ull retort', with n Water seul zit the bottom o'l1 the. retort.

This invention particularly eonsists in eert'nin improvements in the Construction of the retort itself nf'hel'eby a step by Step enlargement ot they urea of the retort from the tol) to the bottoni.thereof is provided for aeeoniplishing the purpose o1 forming' an annulnr t'ree ons spin-e under euch step At'roin whit-h space one or inore branch 'fines lead into one or more inain Auns fines in the retort. This step by step enlargement also nlloivsl a sudden expansion of the cool it intervalsy as it passes down through the retort inst' `.ad o'l the gradual -expansion oil t ie coal' as is usual.

.t practical enibodinient of my invention is represented in the ueeoinpanying drawings, whirl: show u bank ot tour retorts, it being understood that the nuniber of retorts muy be varied to nuilfdi tierent requirements.

Figure l is a vertical section taken in the plnnes of the. linesI of Fig'. 2, lookingin the direction of the arrows; Figf is a horizontal set-tion tal-:en in the pinne of the line lfzl') ot Fig. l. lookingl in the direction ol the. arrows; Fig'. :i is a transverse section taken in the pianeo'lf the line C--tl of Fig'. 9., looking' iu the, direction of the arrows; Fig. fi is u plan view of one ot the retort seetions, nud ltig. 5 is a seelion taken in 'the planes ot' the line ll--D oi" Fie'. i., looking in the, di-

reetion oi` the, arrows,.a portion oi? the nentl :nl ioiningr retort seetion being shown in longitudinal vertieul ventral section. f

The tour vertieal retorts l, 2. 3i, 4, :ire nrrane'ed in tivo parallel rows within the Coinbuslion elnnnber 5j. through which ehnlnber, between and around the. said retorts, the 'produets ol' ".oinl'iustion 'from the furnace (i ported by said tioor plate sind by 'tbs strueture of masonry which includes the turnaee Beneath. the Hoor plate l?, l provide i easing 90 into the interior of which project the dip pipes 21 which forni downward eX.- tensions ot the retorts l, 2, 3, 4. rihis easing basan upwzirdlyinelined outlet 22 'for the eoke and is further provided with a double inclined main bottoni 23 and n false bottoni 2l. The space between the main bottom and the false bot-toni Q4 is adapted to re` eeive the tur, und n suitable pipe 525 is provided for removing the tar. Yft/'atei' is introduced into this Casing i2() to a pointslighl'ly above the lon/er ends of .the dip vpipes 21, so as to vtorni a wnterisenl for the saine, the spare between the Waiter level and the lioor plate 1K7, forming a ohnmber. A system of pipinga 2i' lends from the desired point.

on shafts 22) belmv the bottoms ot the severalv retort's. which supports also serve to agitizit-e the Coke at. the. bottoms oi the retorts and onus@ the same to be deposited yon to the aise' bottoni oi` the easing'. rlhe two shafts 29 muy b e rotated at the desired speed from any suitable. source of power, not shown herein. Suitable means, not shown herein,- are provided 'tor feeding' the coni e0ntinuonsly into the tops ot' the several retorts.

The eoke is reinoved little by litt-le up Wardly through the inelined outlet, 22, by means of a ruin 3() reeiproent-ing on the false botton 21%, Whieh rain lis driven by s, suitz'ible engine 3l. f

Each of the retorts inerenees in ares step by step from the top to the bottom thereof, so as to serve the double purpose of permit torvals during its downward movement. and also of providing ons .spaces under the able Columns 19 and the retorts are sup-- gas chalutier' 2G for conveying` the ne to {iny- Revolving supports 28 are tixedly mounted ting a sudden expansion ot the. @oei ut in.-v

vided with one'or more main vertical gas fines; in the present instance two of these gas dues 32 are provided, the lower ends of which' are lopen through the floor plate 17 andilining 18 into the gas chamber 26 and the upperend's of which iues are provided with suitable plugs'33 through which steam may be admitted for preventing the over heating and, consequent decomposition of the gas asitpasses down int-o the gas chamber. Diagonal gas tlues 34 lead upwardly :trom the steps in the interior of the retort, into the main gas iues 32, thus aiording an outlet for the gas whichcollects in the spaces beneath the said steps. This gas passes downwardly through these tlues 32 into the gas chamber 26. The rest of the gas passes downwardly through the, water seal at the bottoni of the retort and bubbles upwardly into the said. gas chamber 26.

qWhere the retorts are arranged in parallel series as shown in the accompanying drawings, the two retorts 1 and 3 nearest to theI furnace, are connected to the furnace Wall and are also connected to the next two re- 'torts 2 and 4, so that. the productsof conlbustion as they pass from the furnace 6 through the iue 7, have to first-pass between the adjacent walls of the retorts and from thence to the chimney branch fiues 9, 10, along the outer walls of the said retorts, thus insuring the utilization of the products of combustion to the best advantage. Furthermore, the secondary air which is/introduced through the openings 14, 15,\16, is introduced at the enlarged spaces in the combustion chamber where the secondary air may be readily mixed with the products of combustion from the furnace to produce the greatestheat at the desired points. Another great advantage of introducing the secondary air directly into the combustion chamber instead of into the furnace iue, is that, the greatest heat of the products of combustion is insured within the combustion chamber and not within the furnace tine where the tendency has been to heat the Walls of the furnace tine to a melting point.

The parts of the apparatus shown and described but not claimed herein form the subject mattei of an application tiled by me the. second day of December, 1908, its

' serial number being 465,602, of which applr cation this present application is a division.

What I claim is 1. In an apparatus of the character described, a hretort having its interior enlarged in steps from the top to the bottom thereof to form gas spaces under-'the steps, said rctort having a main gas Iiue therein and branch flues leading from said gas spa-ces into said main gas flue.

2. In an apparatus of the character described, a retort having its interior enlarged in steps from the top to the bottom ythereof to form gas spaces under the steps, said rctort having a plurality of main dues therein and branch titles. leading from the said gas spaces into the said main gas fines.

3. In an apparatus of the character described, a retort composed of sections, the bores of which increase in the top to the bottom of thtietort to form a step by step enlargement of the interior of the retort whereby gas spaces are formed vunder. the said steps, said retort having a branch iues leading from the said gas spaces into the said main gas fines.

' In testimony, that I claim the foregoing as my invention, I have signed my name 1n diameter' from presence ot two witn esses, this twentieth day ot' February 1909.
