VVithin the vaporizing-chamber of the still B is arranged au ordinary coil, B',l and around the outer curved surface of thestill is a jacket, C,

which is so arranged in connection therewith as to leave or furnish a superheating steamchamber, C1. Steam from a boiler suitably arranged is, by means of the pipe (l2, supplied to this chamber G1, and after passing under and around the lower section ofthe. still B gy means ot the pipe U3 is conveyed tothe coil By rcicrcnce to the drawing it will be seen that,y in consequence otzmy arrangement of the still B and jacket (l in connection with the fire-pot of the furnace, while the jacket entirely protects the still-B from the direct action of the heat, yet the same is itself so` acted on as tofinsnre the super-heating of. all steam. admitted through'the pipe (32 as it passeslhrough the chamber (31, and,y consequently, under and in direct contact with the still 'B,in which superheated condition through the pipe Cs it is fed to the coil B.

From this reserv voir E, by means ofthe valve E1 andjacketed pipe E2,th' e lquillized crude turpent-ine is fed, as occasion may require, tothe eva'poratingf chamber of the still B. This valve E1 is operated'so as to be opened and closed at pleasure, by means ot' a valve-rod and lever, E3.

N'Yithin the liquidizing-chamber D1 is secured, on a vertical shaft, F1, the rake or stirrer F. The shaft is secured so as torevolve freely in suitablelbearings on the upperand lowersurfaces of `the'chamber and atthe centers .theref of, while ythe rake or stirrer F is constructed of any suitable` material', and is lof the form clearly 'shown'on the drawing. Around the interior wall of this chamber D1 is a perforated coil, Ffwhieh isv designed to emit jets of steamthro'ugh the mass of crude turpentine,

it aids in liquidizing the crude inaterial.-l The sections of this pipe" Gr, which arewithiuthe reservoir E andchamb erl)1, are perforated, as "clearlyf's-hown at G1 G?, "H iS lib separator, and consists cfa 'column' hay? series ctraysforpartitions 'E1 H1, having cpr-.nin gs" at vtheir centers, over which are dedectingcaps Hz H2. Immediately below these caps are openings or orifices leading into the inte-4 rior chamber of the separator, which allow of the free passage of all the products of evaporization which are driven into the separator.`

Through an opening infeach of the trays H1- H1 is secured a pipe, H1, the upperv section of which is immediately below the orificev through which the caps H2 H2 deflect the vapors, acid,

From the center of thesdome of the separator leads a pipe, L, which communicates directly with the condensing- Worm L1, and which is ot' ordinary construction, and iucased in a water-tight tank or vessel, L2, in the usual manner."

a( the apparatus will be readily understood. 'lhe crude material is poured into the chamber D1, and steam is supplied to the perforated coil F2. Motion is then imparted to the shaft F1, which revolves rapidly the rake or stirrer F. This rapid agitation of the mass by the rake, in connection with the jetsof steam and the heatffrom the section G2 of the pipe G, in a at the desired temperatureby means ofthe section G1 of the pipe G. Thecoil B1 i-s `con-v tinually supplied'with superheated steam .from the chamber C1. The valveV E1is now. opened by means of the valve-rod; and-'1e verE 3, and through the jacketed pipe E is su-'ppli'edto the still Bthe llipiidizedturpentine, r--tvfhere,

- at an exceedingly'low temperature, its evaporization is insured. By means off-the y'steam-4 chamber O1, coil B1, and the 'lower 'section of the pipe G, as rapidly -as the evaporization takes place the vapor is fed, by means cffthe pipe I, to the separator H, as visalso any vapor which may be generated in the-liquidiz'- ing-chamber D1,'by means of the pipe l1. En-

tering the chamber of theseparator, it passes up through the opening in the lowertray H1, and, striking against the cap H2, is deflected and escapes by the or-ilice immediatelybelow the cap again out into the chamber and up through the next, and so on throughout the entire series. But in the passage of the vapor through each of thse partitions .or trays H1 and "under the deflectors Ilz it is robbed of more or less of .its` pyroligneous-y acid water, and other impurities, which, being heavier than the vapor, falls and accumulates on theptrays, while the vapor continues its as- But this acid wat-er and the other impurities canonly accumulate to a certain depth, because so 4soon as they reach a point ushwith-.th'e upper openings of the pipes Hf H theybegi to flow down from one tray to another 'untilthey reach. the bottom of the separator H, fromwhich they are conveyed by the pipe` K1 tothe vessel K, to be drawn odas-wanted by means of the cock K2. vThe vaponthusnow comparatively free from vthe acid ater, is conveyed by the pipe L to the wenn .'L1, where its condensation Vtakes place. Butin the process of condensation of the turpentineconsiderable steam or moisture has also been condensed, of which it is most `dei siable to free the v turpentine, therefore, from-- the Worm L1 the turpentine and condensed steam are conveyed together to the vessel M by means of the pipe M1, which pipe'enters at the llowersection of the vessel. The water, being heavier than the turpentine, remains at the bottom, and the turpentine rises until it reaches the opening through which enters the pipe'N1, by which pipe, in a pure. state,'the

turpen'tine is conveyed to the vessel N, and

from which it is drawnoff into barrels. The liquid resin from the still, thepyroligneous acid Water from the vessel K, and the condensed Water from-'the vessel are all drawn oil, as clearlyfshown. o

From the foregoing description it will readily bei seen that each and everystage of the v process is carried on in the apparatus at one and the same time.
