and ascend to the globep, al d pipe or goose-neck
j, they will, by means of their contact or impinge-
ment against the surfaces of this said globe and
pipe, which, being in the outer air and exposed
relatively to a lower or cooler degree of temper-
ature, to some extent be condensed, and there-
fore divested of a considerable portion of their
heavier or liquid particles, which, by their own
superior gravity, will naturally fall back to the
boiling-chamber, leaving only the uncondensed
or lighter vapors to pass on through the goose-
neck or pipe j to the vessel k. This latter ves-
sel k is provided with condensing-plates, so con-
trived and arranged as to receive the vapors
against their lower surfaces, and, in their pas-
sage, are also forced through an accumulated
stratum of liquid upon their upper surfaces by
means of the inverted cups h placed over their
outlets or perforations, as shown on the drawing.
The contact of the vapors with the pipe jand
the lower suni-eces of the plates above mentioned,
and their passage through the liquid upon their
upper surfaces, as above described, will com-
pletely divest them of all the woody, vinegar,
or pyroligneous acids or other impurities which
they may contain at this stage or condition of
the distilling operation, and the vapors which
remain will pass on to be liquidized by the con-
densing-worm n, which is immersed in cold water
for the accomplishment of this purpose, and
finally be discharged at the terminus of the
worm-pipe by means of the stop-cock o. The
vessel in which the condensing-worm n is placed
is supplied with a constant stream of cold water
by means of an inlet or feed-pipe, s, which ad-
mits the water at the bottom of this vessel, and
as it becomes warm, by reason of its contact with
the worm un, ascends to the outlet-pipe t, where
it is wasted or perhaps used for the supply of
the steam-boiler or boilers, which it is necessary
to use in connection with my apparatus.
The condensed and impure liquid which may
be accumulated in the bottom of the vessel l
may be returned to the boiling-chambergthrough
the pipe a, which is provided with a stop-cock,
s, or it may be drawn off or wasted by means of
the pipe wo communicating with the bottom of
said vessel, and which pipe is also provided with
a stop-cock, shown at x.
It will furthermore beperceived. byreference to
the drawing, that the still H is divided into three
chambers, the objects of the upper or boiling-
chamber of which having been herein partially
described, it remains for me only to mention that
it is further provided with an opening or man-
hole at the top, and with one or more at the sides,
if necessary, both or all of which are provided
with covers tightly fitted and secured in the usual
manner. Through these man-holes are inserted,
when required, chips, knots, wood, or sawdust
of pine, and the turpentine which they contain
is extracted from them in precisely the same man-
ner as herein described for the distillation of the
crude orraw turpentine. The bottom of the chanm-
ber g is likewise provided with a slide-valve, y,operated by the valve-rod c', which serves the
purpose of discharging the residuum or resin
through the middle chamber D to the lower or
discharging-chamber E. The bottom of the mid-
dle chamber is perforated for this purpose. From
this chamber the resin is discharged through the
pipe B, which is provided with a stop-cock, O.
The pipe B aforesaid is provided with a bell-
shaped mouth-piece, as shown, so as to receive
all the liquid resin as it descends from the cham-
ber above it.
It may here be stated that the steam which has
been admitted through the coil-pipei for the pur-
pose of boiling the raw or crude turpentine is dis-
charged at the terminus F of this pipe, where it
will be forced in direct contact with the resin as
it descends from the boiling chamber g. This
pipe is provided with a valve, P, to regulate the
discharge of steam into the chamber D. It is
this contact with a steam-jet which effects the
bleaching and purification of the resin, for which
object I claim my apparatus to be applicable.
Sulphurous-acid gas or the fumes of burning
sulphurmay alsobe introduced into contact there-
with for a like purpose.
The chamber E is provided with a stop-cock,
R, at or near its bottom, which is intended to
serve the purpose of discharging-the condensed
water which will accumulate therei.
A vacuum-valve, S, is provided on the globe
above the still, for the purpose of providing
against accident.
An indicator or eye-glass may be placed on
the still in the usual manner, so as to indicate
the quantity of liquid therein.
It is clearly evident that the different parts of
my apparatus may be constructed in almost any
desired form and dimensions without, in any
manner, changing its general principles or with-
out defeating or injuring the objects for which
it is intended, as herein set forth. It will, I be-
lieve, be necessary, however, to construct all the
pipes to which allusion herein has been made,
of copper, as likewise the vessel k. The shell
of the still, the charger, and condensing-vessel
may be made of wood.
Having described my apparatus, what I wish
to secure by Letters Patent is the following:
1. The still H, divided into the compartments,
as stated, and the pipe i, so combined and ar-
ranged that the latter shall act both in the va-
porizing-chamber g and the bleaching and puri-
fying-chamber D, substantially as described.
2. The receiver and charger A and still H,
each constructed as stated, and the pipes i and
j, the same combined and arranged so as to op-
erate substantially as described.
3. The receiver A, still H. and vessel k, each
constructed as stated, and so conn ected with each
other and the condenser by pipes j i as to oper-
ate substantially as described.
