"
1, WILLIAM VOGEL of Chicago, in the County of Cook, State of Illinois,
Manufacturer, do hereby declare the nature of my Invention for A PROCESS
AND APPARATUS FOR EXTRACTING CARBON FROM FURNACE FUMES," and in what
manner the saine is to be performed, to be particularly described and ascertained
in and by the following statement :-
My Invention relates to an improvement in apparatus for and process of
consuming smoke, and is designed to be attached to, and operated in connection
with steam boilers, and other furnaces of the ordinary construction.
The object of my Invention is, first, to consume the smoke from the furnace
second, to separate the soot and other products of combustion from the smoke, and
deposit the same in the form of lamp black, of commercial value, in the bottom of
the cylinders; third, to conduct the gas resulting from the decomposition of the
smoke into the furnace, and to use it as an auxiliary to the fuel therein.
The accompanying Drawing represents an apparatus embodying my Invention.
Figure 1 is a vertical section showing the apparatus attached to the furnace.
Fig. 2 is a side elevation. Figure 3 is a horizontal section on the line X-X
Figure 2. Figure 4 is a top plan view.
A, represents a cylinder, that is made of boiler plate or other suitable material,
and has located in it and secured in place, a number of small cylinders B, grouped
around a central cylinder H, as shown. These cylinders are connected together at
their upper and lower ends, as at A¹. An inlet pipe I is connected to one of the
cylinders B at the lower end thereof, and an outlet pipe K is connected to the
upper end of the cylinder H. A water pipe L passes under the cylinder A, and is
connected to the small cylinders, as at M. Cocks N, allow the water to be intro-
duced into or drawn from the group of cylinders. Extending vertically through
the small cylinders, and journaled centrally therein, are the shafts O, which have a
number of radial beaters P, projecting from them. From the inner side of the
cylinders project the arms Q, which are so arranged as to be out of line with the
beaters P. Upon the central shaft O¹, is affixed a spur wheel R, and to the shafts O,
are secured the pinions S, which mesh with the wheel R. By means of a pulley T,
the shaft O¹, is rotated, and its motion, by means of the gear wheels R, S, is
imparted to the shafts O, in the cylinders. Connected to the inlet pipe I, is .a
blower V, and communicating therewith is a cooling chamber W, of any suitable

page_text: construction. In Figure 1 I illustrate a furnace C, of which D, represents the fire
chamber, E, the grate, and F, the ash pit. A pipe G, leads from the flues of the
furnace to the cooler W, and the outlet pipe K, terminates at a suitable point below
the grate E. X; represents water indicators.
The operation of my Invention is as follows: The small cylinders are filled with
water up to a suitable point, as shown. The smoke passes from the furnace
through the pipe G, into the cooling cylinder W, from thence it is acted upon by
the blower V, and forced through the pipe I, into the bottom of one of the
cylinders B, up through the water therein, into the air space Y, from thence
through the opening A', into the adjoining cylinder, down through the water in
said cylinder, and through the opening A', into the next adjoining one, and so on
through the entire group. The smoke during its passage through the water in the
cylinder, is constantly operated upon by the beaters P, and arms Q, and by the
time it reaches the cylinder H, is entirely decomposed. The soot gravitates to
the bottom of the several cylinders, and is there deposited in the form of lamp
black, of commercial value. During the passage of the smoke through the water in
the cylinders, A gas results therefiom, which is fed through the pipe K, to the pit
in the furnace, as previously stated. By means of my Invention, I consume the
smoke collect the valuable lamp black which would be otherwise wasted; and
. produce a gas which is valuable as an auxiliary to the fuel in the furnace.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is,
1. The process of consuming smoke, which consists of forcing it through a series
of vessels filled with water and subjecting it to the action of the beaters or agitators
therein, substantially as set forth.
2. The combination of the cylinders B, water supply pipe L, 'beaters P, and an
inlet pipe, substantially as described.
3. The combination of the cylinders B, H, water supply pipe, inlet pipe 1, blower
V, and an outlet pipe K, with beating devices that are adapted to be operated
within the cylinders, substantially as shown and described.
4. The combination of the cylinders B, H, water supply pipe L, inlet pipe I,
blower V, cooler W, and an outlet pipe K, with beating or agitating devices that
are adapted to operate within the cylinders, substantially as specified.
