IMPROVEIIBNT IN BXTRACTING SPIRITS QF TURPBNTI'NE FROMPW WOUD.

meeneem :em-maremma um nmz ma mien; pandora sma- To allwhom ttm/ i1 Be it known thaty I, IAMus'D. STANLEY, of Wilmington, in the county dfNew Hanover, in the State 'ofNorth Carolina, havefflnvented a new and improved Mode of Extracting, Purifying, and Separating, by one andthe same Process, from Pine Wood, White Spirits cf Turpentine, Oil, Tar, and Iuflammable Gas, leaving a. residuum of charcoal;l and I do hereby declare that the following is a ihll and exact description thereof,

dt=oth6t Silitable, substanceor. substances,4

thrcughswhich-the spirits of turpentine, oil, tar, 8vo.,

are passed in-,theform vapor, and so puried, and ieuce carried to the ccndensers X E, iixedin cisterns or cast-iron, or other suitable substance.

The door T is closed air-tight, by means of screw b and bracket l. l

P is a disk-valve, opened or closed by means of rod E and handle o.

Z is a stop-cock. Y

The top of grate-bars O is six inches abovethe bottom of retort G.

Wireuae supports, i i, are stretched across purifier to sustain or separate purifying-substance or substances. v

Purliier K has, at one end, the perforated sheet of iron F, and wire gauze stretched across it at Y, to retain in 'place the purifying-substance L.

The condensers E and X are of copper, or other suitable material, and of the form of a hollow cylindrical ring, and xed. in cisterne O and D, which are kept full of wie water.

Condenser X has oneeock, near its bottom, for running oii its contents.

Uondenser E has theeock d for running oii oil, tar Sto., and cock o for escapo cf inllammable gas.

Oock f is fm' any residue of tar, .Sta

Gauge-cook o is for regulating the amount of water, introduced into the retort through pipe s while distillation ci white spirits is going on.`

The retort G, having been filled o1; charged with pine wood, and water introduced to the depth ci top of grateand D. The retort G andpuriers 11 and K may be of wrought bars O, the doorT cltsed, cock Z closed, and valve P opened, heat is applied, either as shown in accompanying drawings, by fire in the furnace underneath the retortthe draught passing through fines W W, over the retort and oii' through smoke-stack H, or by the introduction of superbeated steam into the retort.

The white spirits of .turpentine now pass off in vapor through valve P, purifer I, and pipe V, into condenser X, and are thence drawn oli purified and free from As sconas these s'pirits begin to show color, valve colored.spiritsoil. tar pag I puri lier K, into condenser lh.,

Thel pyroligneous and acetic acid retained in the pm'ifyingsubstances L and M, rated from them with less tmuble and expense than by the ordinary method.

The advantage this method of obtaining white spirits from wood has over any other heretofore known or used is, that byclosing the valve P,'as soon as the spirits .passing through it begin to show color, the purilier I and contents, pipe V, and condenser X, are kept clean, so that white spirits can be run through them from subsequent charges; whereas, if coloredspirits were suered to pass through themonce, they would have to be carefully cleaned (a' very diiiioult matter) before they could run white spirits again, and colored spirits white, or nearly so.

fore required several.E

What I claim as my invention, and desire to secure by Letters Patent, isv A new method of extracting, separating, and purifying, by one and the same process, ilom' pine wood, white spl 'ts of turpentine, oil, tar, and inflammable gas, byapplying to a retort two purifiers connected with two condensers, in the manner and with the appliances herein described, or any other substantially the same, and which will produce the intended etiect.
