Specification of Letters Patent. Patented Apr. ll, llfi ll fim Application filed November 26, 1915. Serial ltorflfldtfi.

' thecompact grouping of a series of such'r'etorts, and to simplify and cheapen the construction of a furnace having such series of retorts, These objects I attain in themanner hereinafter-set forth, reference being had to the accompanying drawings, in which Figure 1 1s a transverse vcrtlcal section of a furnace constructed in accordance with my.

invention; Fig. 2 isa horizontal section of the same on the line a a, Fig. 1, Fig.3 is a vertical section of one of the retorts and of, the fireplace associated therewith, said section being taken on the line -4), Fig. l,

and Fi 4 is a horizontal section similar to 'Fig. 2 ut'on a smaller scale and omitting "the retorts, this view illustratinga modifica- 'tion of the invention.

I The furnace has a central stack structure 1 containing a stack chamber 2 and providing a seat forthe metal stack 3 when the same is used. Radiating from the central stack structure are a series of fire laces (eight in the present instance) 'each 0 these I fireplaces having 'a'combustion chamber 4,

till

. attachment thereto of the usual condensing I a grate 5;, and an ash pit 6, and crossing each combustlon chamber from back to front is.

a retort 7 whose neck projects throu h the h'ontwall of the combustion chamber or the neck, such as shown by dotted lines in Fig. 1. Each of the combustion'chambers is connected/to the chamberiQ by means of a flue' system comprising a descending flue 8 which is'in counication at the top with the combustion chamber at through a. flue 9 and at the bottom with the stack chamber 2 through a flue 10, the inner end of the retort bei.

eosed to the products of. combustion de-' ecending the flue 8, as shown in Fig. 1, The front wall of the fireplace is inclined backwardly from bottom to tog, so as to-permit the desired projection of t check of can readil tort, and to deflect toward the flue 9 the grod4ucts. of combustion rising in the cham- The descending flue is deflected forwardly in line with the inner end of the retort by means of a projection 11- formed on the stack structure 1 as shown in Fig. 1, hence the products of combustion in each fireplace are caused to pass first around that portion of the retort contained in said combustion chamberand then to descend the flue 8, and

in traversing said flue are deflected into con tact with the inner end of the retort, thus insuring contact of the roducts of combustion with all portions 0 the retort not actu-' ally embedded in the supporting walls, the result being that the contentsof the retort not only have their temperature quickly raised to the distillation point but such distillation process is quickly completed. The

, lower end of each descending flue 8 is also in communication, through a short flue 12, with the ash pit 6 of its correspondingfireplace, and said'flue 12 contains a check draft damper 13 which may be 0 ened when it is desired tocheck the dra through the flue 8 or closed when full draft through said flue 8 is required.

The stack chbcr 2 extends below the flues and the lower portion of said stack chamber communicates with a tunnel 1a through which access may be had to the interior of the stack chamber for cleaning the same, or for other purposes, the inner end of said tunnel being normally closed by a .door 15.

ile I have shown my invention'as applied to a furnace havingthe fireplaces and retorts grouped around acentral stack, and

while prefer this-arrangement because it simplifies construction and reduces cost, the flue system which it havedcscribed can with like good results be employed in connection with a furnace havingbut a single fireplace.

In the construction of the furnaceheretofore described and shown each retort is acted upon only by the products of combustion from its own fireplace but if it is desired to mingle the products'of combustion from the difl'erent fireplaces and then distribute such mixed products of combustion to the various descendin flues 8, this be accomplished providing, at o the separate upper fluent,

9 back flue communicating at the top with the a combustion chamber of said fireplace and chamber, a fireplace at one side thereof, a

' 7 back flue communicating at the top with the combustion chamber of said fireplace and at the bottom with the stackchamber,

and a retort mounted in said fireplace so as to extend across the combustion chamber thereof, the inner end. of said retort being exposed to the products of combustion descendingthe back flue.

2. A distillation-furnace having a stack chamber, a fireplace at one side thereof, a back flue communicating at the top with the combustion chamber of said fireplace and at the bottom with the stack chamber, and a retort mounted in said fireplace so as to extend across the combustion chamber thereof, the inner end of said retort being exposed to the products of combustion descending said back flue, and the latter having therein a projection for deflecting said descending products of combustion for;-

wardly against said inner end of the retort.

3, A distillation furnace having a stack chamber, a fireplace at one side thereof, a

at the bottom with the stackchamber and also with the ash pit of the fireplace, a check draft damper for opening or'closing the latter communication, and a retort mounted in the fireplace so as to extend across the combustion chamber thereof, the.

means inner end of said retort being exposed to the products of combustion descending said back flue.

4:. The combination in a distillation furnace, of a stack chamber, a fireplace at one side thereof, said fireplace having a backthrough the backwardly inclined front wall of the fireplace.

' 5. The combination, in a distillation furnace, of a central stack structure with chamber therein, a series of fireplaces grouped around said stack structure, a series of descending flues each communicating at the top with the combustion chamber of one of the fireplaces and at the bottom with the stack chamber, and retorts mounted in said fireplacesso as to extend across the combustion chambers thereof, each of said retorts being exposed at its inner end to its respective descending flue.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
