This burner is mounted upon a stand S and has heut-ath it a gas pipe b to supply thv startinglieat to get the litirnvr B into action.

The retorts R :trv cinistructvfl its seen in Figs. 4 to 7. Thej-` :we cast 'i oi. piece with svrt'e a dcuhle purpose.

holes in the vnd heads are arranged. one oppositif A:ich vnd of each channel. These holes ln the tirst place they )ivi-init of the proper support of the co1 es :it hoth ends in order to render possible the casting of the haliie plate.. and heads in one piece with the sides of the retort. These holes also serre :in important function after the retort put in service. as the)v permit, h the removal of the screw plugs, of the introduction ot- Scrapers for cleaning out the dvposits m" cai-lion and other iesidiuun which accumulati-s front time to time in the retort. A. svvn in Figs. 4, C, and T. the both.v of the .rvtort hetwevn the ends is flat :it tht` top and gradually narrows toward the bottom and i has a rounded bottoni, but, if desiretl, the

approximate-l5Y equal to the thickness of the inasoi'ir)Y wall in which the retort ends :tre carried. .\t the smaller end R of the retort there is :t ci)rrespondiner ril) or flange hut this does not. extend all the tgay to the top of tliv'retort, but tapers to nothingr near the top eoincideutly with the recesses if* fl which reduces the thickness of this end of the retort. The larger end R of the retort descends t. r; below the level of the middle of the retort, :is seen in Figs. 5 and (3, while the smaller end R terminates at the bottom coincidently with the bottom of the middle' of the retort. The construction ofthe retort as thus described, has reference to the setting of the retorts and the removal of any one of them' without disturbing the others. Thus the retorts are set with their ends in the front :md back walls and with their ribs 4r abutting against each other. The space between the large ends oftheretorts formed by the abutting ribs r ris lilled with mortar at ni 'nif".

l., the ribs holding the mortar against fall-v ing into the furnace thus forming a tightly lated joint. In like manner, tue ribs or flanges j', j', at the. small end are abutted together aint the space between these ends out-v side of the llanges f is also lilled with mortar the tlanges serving to prevent the mortar from passing into the furnace. lt will be seen, however, that as the end R2 is both narrower and shallower than the end lt, the i'ctort can, by simply loosening the niortai' at front; and bach, be easily slipped out7 the ,i A l ena lt toieniost, toi any repairs or cleaning ln setting the retorts` and 2^ supply the feed devices 5, of therl burner, which may .be of any desired type. At a point higher up and opposite the lower endslof the lower tier or retorts are two other? branch pipes l" .and 2" which supply the devices for the retorts, the oil passingl through the pipe l" and the air through 2". llach retort has an independent feed device, .the construction and arrangement o' which shown in detail in luig. 25. its relation to the retort being shown in Figs; and 5. 'l'he feed tube Y", Figs. l and .3, is made with an external screw thread if which is screwed into a bushing in the head lt2 of the retort, and terminates: within the retort in a tapered nozzle. rl`he outer end olt the feed tube V, Fig'. Il, is screwed into a T-coupling y2, into the horizontal nipple ol' which is screwed the air nozzle y taking air l'roni the coupling Y which is placid in the length of the air pipe "D, one opposite each retort, and which pipe extends past and supplies all the retorls of `hat series. 'l`he valve f/ has its seat between the coupling Y and the nozzlel ,f so that any retort can be cui oil' l'roiu the air pipe without interfering' with the passage of aiil past that retort to others in the series. ln the upper nipple ol' the T-coupliiig is screwed an upright tubular frame of .special forni which receives oil t'roin the oil pipe lb through valve the coupling- X. placed in the length ol' oil li uliwrs llt f which they may be turned.

coupling X is screwed on to the top of tubular traine l and within the latter is a tapered bushing w which causes the oil in descending to pass down in a centralized stream. 'lo make the passage of the oil risible lor adjustment purposes,A l provide in the tubular traine Il a special forni of sight feed constructed as follows. ()n opposite sides ot' the tubular frame il are formed Circular ll-.uiged openings screw threaded inteiioily and haring circular glass plates c c clamped in the saine by meant-z 0f externally screw threaded rings .s s which are provided with nicks or notches to receive a tool by lly means of these rings the glass platesl are clamped in place on opposite sides ol' the tubular frame lil :o as to forni windows through which the passage of oil in a stream from the tapered bushing .'u may be obse 'ved7 thus enabling the operator' to regulate the vfeed ot' oil and determine whether any one or' the retorts is acting properly, or whether it is clogged.

.As the oil and air are l'ed into the .smaller ends of the lower series of retorts, it beeoines gasilieil as it passes through the prolonged channelway formed by the ballle plates f/and as it issues from the top of each lower retort it passes through a by-pass pipe .i which connects the upper screw' threaded openingr of each lower retort with the lower screw threaded opening of each upper retort, the retorts being thus coupled iii pairs:

.vertically to secure a pirt'ect gasilcation of the oil. 'l'his by-p: .5s is made with a union joint where it connects with the retorts, so that it may be quickly uinzoupled'to permit any one retort to be talien out without disturbing' the others. .\s the newly formed gas issues from the upper tiel' of i'etorts it pit-ses by pipi-s .\l'' into a large manifold vpipe .\l which runs alongl the full length ot the upper tier of retorts and from which an lip-lake pi eli with Valve n leads toa large horizontalltrnnl( pipe 'l` that may connect w ith any number ol' lgenerators and then extend lo the gas holder or point of utilization.

ln the manifold pipe .\l opposite each ontlet pipe ll: is a removable .screw plug mi* Figs. .l and which permits a longseraiier tool to lit passed straight' through the mani fold pipe and through the pipe .\l`' and into the upper cliannelwayv of the retort'to clean out 'of the same any deposite of cai-hon. For thel .saine purpose the manifold pipe has in its' closed end a removable screw plug 1li,g l"i; l` arranged at the bottoni of the inanil'old and in alinement with the outlet pipe m', thus permitting thtI manifold to be cleaned of its deposits. The pipe '//i leading l'roni the manifold is provided with a valve and may he employed for taking oli' gas to any desired point. I

',l`lie llames and hot gases t'roin the burner ll circulate around and between the retorts,

'which hy the spacingr ot' their ahuttineY rihzsl 1' and j', and the shape o1" their middle portions. allow the currents to pass up hetwvvn Q the same. thusl uniformly. and thoroughly;

'l'his gi'rvstgreat ta -cility for thv removal ot' the retorts individ- 30 ually, and constitutes onv ot' thv practically valuahle features of my invention. however, there ma)v he .some leakage of gas past t the heads ot' the retort. or through the numerous plugs in thv ends of thv -atne. l provide at each end of the furnace a housing or hreevhingr l) of heavy sheet metal which extends around and in front ot' hoth tiers of rvtorts. and these housings l connect h r I ott-take pipes D D with the smoke tine. so that no otl'ensire gases may find their: way out to foul the atmosphere for the operatives. These housings' are made in .sections which join on horizontal lines on the level of the inlet and outlet pipes V. and ML'. so that the housing may he conveniently removed when -it is necessary to clean out or remore any one of the retorts.

The roof of the furnace is formed of fire bricks I carried on inverted T-hvanis. as .seen 49 in Fig. 1, with covering plate and cross rods .l connecting the two tace plates A ofthe furnace. These face platesor furnace fronts are cast with nzarginal flanges A to which the housing plates are attached.

The two tiers ot retorts are sustained at their ends upon cross hars of channel iron N X. .The cross hars N which su-taia the large ends of the retorts are of less height than the liars N which .sustain the small ends. 50 so as-to hold the retorts lvvvl. lt will also be seen that hy having` thv large ends of thv upper tier of rvtorts reversed to that of the lat- Jer vnds of the lowvr livr. the saine pa!- tern of retorts serres for hoth tiers. only rvquirinp; that the retorts of thv two tiers he taken out from opposite ends.

In the sides of thv t'urnacv on a level with vthe hottoms of the rvtorts are peep holesl H Il, provided with rotar)y damper doors for ohsel'vin; r the color and temperature of the vretorts.

In defining: my invention more clearly, l would state thatl the ends of the rvtorts are rectangular and upright or with a greater va'tival dimensiomthan the horizontal dirisible through the end wall? of masonnv.

t inension. and have parallel sides which fit close up to the sides ol' the ends of the adjacent retorts with a straight vertical joint' which tillvd with mortar without the clitA ting and tittin;y ot' ln'ivlts between, and the removal of which mortar joint permits the convenient rclnoral of any retort without tvarin;r out ln'ivlt worlt' or disturbing the adf jacent retorts. l: will also he seen that the i plugs which clo.-.e the holes in the heads of the retorts aresiinple imperforate screw plugs with .square ends and are wholly disvonnvvtvd from each other so that an) one j may hv removed to vh-an out an olistruvtcd l channvlwaj' without distal-hing or opening ilthv others.
