ARCHIBALD K. LEE, OF GALVESTON, TEXAS.
IMPROVEMENT IN APPARATUS FOR DISTILLING TURPENTINE.
Specification forming part of Letters Patenl; No. 117,549, dated August 1, 1871.To all 'whom it may concern:
Be it known that I, ARCIRBALD K. IEE, Of
the city of Galveston and State of Texas, have
invented a new and improved Apparatus for
Distilling Turpentine and for Bleaching the Rles-
in or residuum thereof, of which the following
is a correct, clear, and full description and spec-
ification, reference being had to the drawing an
nexed which constitutes a part of said specilica-
tion and description.
My invention has for its primary object the
production, in as cheap, simple, and as effectual
manner as possible, from the chips or pieces of
pine wood or sawdust of the same material, or
from the crude turpentine obtained in the usual
manner from pine trees, a perfectly pure, limpid,
and as perfect an article of the spirits of tur-
pentine as can beproduced by anyknown means;
and secondly, thebleaching, purification, and def-
ecation of the resin or residuum thereof, so as
to produce, in the highest degree, the most de-
sirable, marketable, and profitable article fior the
requirements of commerce, and, therefore, of the
greatest benefit to the manufacturer.
My device is of simple construction, and does
not materially differ in its general principles,
arrangement, and operation, from an ordinary
distilling apparatus, such as is now almost uni-
versally used in practice; but it possesses feat-
ures, and peculiarities, and advantages which,
in the result of its operations, place it in the
most eminent degree far above anything of the
same character of mechanism hitherto devised
and brought into practical use, not the least im-
porta.nt of which is, the production, as above
stated, of an article of turpentine perfectly pure
and free from the pyroligneous acids and other im-
purities which usually pertain to the spirits of tur-
pentine produced in the usual and ordinary man-
ner. That the resin or residuum which remains
after the process of distillation should likewise
be perfectly and entirely free from all feculent
or foreign matters or impurities which diminish
or depreciate its value for the purposes of the
arts 'or manufactures is furthermore a consid-
eration of the highest pecuniary importance to
the producer.
The production of a good. and valuable ar-
ticle in commerce, manufactures, or the arts, es-
pecially of the character to which we allude, be-
gets economy in the cost of the vessels intowhich it is to be retained or stored, as well as
economy in the cost of handling and transpor-
tation to a market. Besides, the manufacturer
or producer has the extreme satisfaction of hav-
ing made available to the utmost extent for the
production of a profitable result all the means
at his command. A good article likewise meets
with ready sale and quick returns, while an in-
ferior article may remain, especially in a dull
market, upon the hands of the producer to his
great injury, detriment, and possible loss.
My device accomplishes all the good and de-
sirable results sought to be attained, and there-
fore avoids all the evil ones to which allusion
herein has been made, and will be more readily
understood and appreciated when its mode of
construction, arrangement, and operation has
been made familiar by the drawing annexed,
wherein the letters refer to the different parts
thereof, and in which-
A represents the receiver or charger, divided
into two compartments, the upper one of which is
for the reception of the crude or raw turpentine,
and in which it is to some extent partially or com-
pletely liquidized by means of the heat of the
vapor - pipe j, which passes through it. The
opening of the slide valve b by the means of the
valve-rod c admits the liquid and warmed raw
material into the lower or charging-chamber d,
where it is further heated by a continuation of
the vapor-pipe j, above mentioned, preparatory
to its reception through the pipe e, which is pro-
vided with a stop-cock, fJ'into the boiling or va-
porizing-chamber g of the still IH. The boiling
and vaporizing process is effected y5 means of
the pipe i, into which steam is introduced from
the boiler or generator which it is not neces-
sary for our purpose to describe or to show on the
drawing. The vapor which is generated by the
boiling process aforesaid is immediately passed
to the condenser through and by means of the
pipe j, vessel k, and pipe 1, a continuation of the
latter forming the condensing-coil or worm n,
provided at its outlet with a stop-cock, o. At
this outlet the spirits of turpentine, in a per-
fectly pure state, is discharged into barrels or
other vessels prepared for its reception.
It will now be perceived that as the vapors
are generated from the raw or crude material in
the boiling-chamber g by means of the steam-
pipe i, to which allusion has already been made,
