UNITED STATES PATENT OFFICE.
SAMUEL IH. SPANGLER, OF PALESTINE, TEXAS, ASSIGNOR OF ONE-HALF TO
L. LEWENTIIAL, OF SAME PLACE.
APPARATUS FOR DISTILLING WOOD.
SPECIFICATION forming part of Letters Patent No. 417,752, dated December 24, 1889.
Application filed June 20, 1889,. Serial No, 314,948, (No model.)To cell whaon it 7inu cocerio:
Be it known that I, SA IMEL H. SPANGLER,
a citizen of the United States, residing at Pal-
estine, in the county of Anderson and State
5 of Texas, have invented certain new and use-
ful Improvements in Furnaces and Apparatus
for Distilling Wood; and I do declare the fol-
lowing to be a full, clear, and exact descrip-
tion of the invention, such as will enable
1o others skilled in the art to which it appertains
to make and use the same, reference being
had to the accompanying drawings, and to
the letters and figures of reference marked
thereon, which form a part of this specifica-
15 tion.
My invention has relation to improvements
in furnaces and apparatus for distilling wood
of that class wherein the liquids of the wood
are extracted by subjection in a closed heated
20o chamber or retort and carried by vaporization
through the process of distillation to conden-
sation.
The improvements involved in my inven-
tion are fully illustrated in the accompany-
25 ing drawings, and hereinafter I have specifi-
cally described the same, so as to distinguish
my invention from other inventions.
In the drawings, Figure 1 is a front view, in
elevation, of the furnace. Fig. 2 is a rear view,
30 in elevation, of the furnace, a portion being
shown removed to illustrate the retort-pipe.
In this figure are also shown the receiver, the
dome with the deflector, and the exhaust-
pipe. Fig. 3 is a longitudinal central section
35 of the furnace and retort and vertical section
of the retort-pipe, the receiver, and dome,
a car being shown in position in the retort.
Fig. 4 is a view of the water-box and con-
densing-pipes with the discharge-pipe.
40 A designates the brick-work of the furnace
having end walls and side walls to properly
inclose, surround, and support the retort.
In the front of the furnace are openings 1
and 2, the former leading into the fire-cham-
45 ber of the furnace, and are closed by doors
3, properly mounted and closing tight, and
the latter openings 2 leading into the ash-pit
and provided with doors 4 to close them. The
fire-chamber is provided with grate-bars 5, ar-
50 ranged over the ash-pit 6, with one end rest-ing in the front wall of the furnace and the
other or rear end resting on the bridge 7, the
lower part of which forms the back wall of
the ash-pit, and the bridge being built to a
proper height in the furnace to throw the 55
flames upward and into the combustion-cham-
ber 8 at the rear. Transversely arranged
across the furnace are a sufficient number of
supporting-bars 9, having their ends fixed in
the masonry of the furnace, and these sup- 60
port the retort.
B designates the retort. This consists of
a chilled-iron-plate bottom 10, resting on the
supporting-bars 9, and a fire-clay body 11,
having vertical sides and arched top or roof, 65
substantially as shown. This clay body 11may
be molded and built of plastic material or
composed of fire-clay bricks laid up to suit
the construction, with iron end facings 12 13
at front and rear bracing the masonry of the 70
retort and furnace and having the ends closed
by doors 1415, fitting gas-tight over the open-
ings of the retort. The retort is arranged in
the masonry with a draft-space about its
sides and top, to which the draft of the fur- 75
nace communicates through flues 16, located
at the rear of the furnace. At the front is
the stack 17. The stack or flues are provided
with suitable dampers to control the draft of
the furnace. At the front of the furnace is 80
arranged a pyrometer 18, from which the
condition of the heat in the retort may be
ascertained. In the center of the retort is
fixed the vertically-arranged escape-pipe 19,
through which the escaping gases are carried 85
into a cylindrical receiver 20, located on the
top of the escape-pipe. The escape-pipe ex-
tends up in the reservoir, as shown, with its
open end arranged directly under an inverted
cone-shaped deflector 21, which deflects and 90o
distributes the rising fumes or gases about
in the reservoir, causing precipitation of any
solid or tarry matter which may be carried
forward by the gases. At each end ,of the
reservoir is a hand-hole 22, through which 95
access to the reservoir may be had for the
purpose of removing the deposits. These
hand-holes are covered by caps or doors 23.
In the bottom of the reservoir is a spigot 24,
through which the liquid deposits may be ioo
