IMPROVEMENT IN DISTlLLIN-G PINE WOOD.

Specification forming part of Letters Patent No. 105,019, dated July 5, 1870.

.To on whom it' may. concern.-

Be it known that I, THOMAS W. WHEELER,

of New Berne, in the county of Craven and State of North Carolina, have invented certain Improvements in Process of Distilling Turpentine from Pine Wood, 820., of-which. the fol-=- lowing is a specification, reference being had tot-he accompanying drawings.

My invention relates to processes for distilling turpentine and other substances from pine wood; and it consists in the construction and arrangement of a novel apparatus [by which, during the process, and at one and the same time, the lighter oil or turpentine, the heavy oils, and a tarry residuum, maybe drawn fromdifferent points of the same.

- In the drawing, Figure 1 is alongitudinal vertical section of my apparatus. showing a portion of the same in side elevation.

In the construction of my apparatus 1 make a retort, A, of any 'size desired, and of any suitable form, with a perforated floor or plat-'= form, B, on its inside, and at some little distance from its bottom,.as shown-iiithe figure, and also-with a lid, 0, attached in any of theusual per side an upright cylindrical projection, a,

with a pipe, b, communicating with the retort,

extending up through its center; -'Over this:

pipe b is placed a coveredflcylindrical tube, a, of the requisite size to leave some-space between it and the tube or pipe I) on the one side,.and' the cylindrical projection on the other, as clearly shown inthe figure. Overor near the retort is placed a cold-water cistern, F, provided with a cock, d, and so arranged that the water may be allowed to drip on the top of the tube 0 when desired. To the side of the tube 0 is connected a pipe, f, which runs to a worm-tub, G, .within which it is.-

coiled, and afterward passes out at thel'side near the bottom of the tub, as shown at g. f

The rear end of the retort maybe made square or cone-shaped, as shown in the drawing. 1 In either case a pipe, h, extends fromitsicenter to a worm-tub, H, within which it is coiled,

and afterward passes out at the side, near the bottom of the tub, as shown at hand is provided with a trap, k, between the retort and the worm-tub, as shown. From the bottom of the retort is another pipe, Z, leadinginto a tight receiver, L, with a pipe, m, -extending from it, provided with a trap, n, and also with a-pipe, 0. rising from its upper end, all as shown inthe figure. j

' Underneath the retort is arrangeda furnace, M, with gate N,- in the usual manner. j "111 operatingth'e apparatus thus constructed the retort A is first charged with the pine wood, and the lid 0 firmly secured. Steamis. then introduced through the 'steampipe' E,

.when it'thoroughly fills the retort and dis I solves all the soluble components of the wood. The vapors arising from this distillation pass up the pipjeb. As they reach its top, the heavy oilthe'reinis at; once condensed by the coldness- 'produced under 'theuppe'r end of thcyl inder by means of the'cold water runningpr dripping thereon from the cold-water cistern;

F,.and is'thrown into the retort, while the vapors containing the lighter oils pass'up over the end of the pipe b, then out through. the pipe f, and into its w'orinfin the tub G, which is iull of cold water,.and condenses the .vaporinto' a liquid, which is drawn froin the pipe at g', 'andwhich consists, principally, of

turpentine, though, in a further distillation, .it'is found to'contain paraifine, naphtha,

;At the same timethe vaporsthatare mainly j cha'rged with the heavy oils pass along'th e.

pipe h to the worm-tub H, which is also full of cold water, and in like manner condenses the" vapors into oil, which is drawn from the pipe at c, the trap kin the pipe preventing any of the lighter gases from passing over at the, Whilethe light and heavy'oils are thus being drawn simultaneously from the re'-' tort, the residuum of the distillation of .the wood passes down through the perforatedfioor B, and out through the pipel, into the receiver L, from which it is drawn by a pipe, m, prosame time.

vided witha trap, n, to prevent any escape of gas, The receiver L is also provided with apipe, 0, which is. kept closed during the process, but serves at other times to afford access to the interior. v It ordinarily-takes from fifteen to twenty- I have found that the turpentine prodiiee'd inithis way is of an excellentand useful qual ity, While what Ihave termed the residuum, is found especially useful as a substitute for a coarse varnish.

Having thus described mv invention, what I claim is 1. The apparatus consisting of the retort A,

with pipe E, for the introduction of steam, the

cylindrical projection a, tube 12, covered cylindrical tube 0, with cold-water cistern F, and the pipes f, 7:, and Z, with the connecting-tubs for condensing, when arranged substantially as herein described, and for the purpose set forth.

2. The process, substantially as herein described, of distilling from pine wood turpentine, heavyoil, and tar residuum, separately and at the same time, in the manner set forth.
