I, WILLIAM B. COGSWELL of the City of Syracuse, in the County of Onondaga,
and State of New York United States of America, Engineer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the manufacture of bi-carbonates by the columnar process
and relates to the construction of the column, and not to the chemical portion of the
process.
The object of the invention is to partially at least cool the liquid contents of the
column, or reduce their temperature so that they leave the column cooler than by
the ordinary process, where tubular columns are used without any cooling
attachments.
It consists in the use of internal, or partly internal and partly external cooling
pipes, with the exterior internal surface of which the hot, liquid comes into contact,
and which pipes are kept as cool as possible by maintaining a flow of cold water
through them or by any other equivalent means.
The column is tubular in form and provided with flanges, which are secured to the
preceding and following sections, in any ordinary manner, as the column is built up
of successive super-imposed sections until the desired height is reached.
Each section may be provided with rectangular nozzles formed integral with the
body of the column, opening outward, and into the interior of the section, the
openings being usually rectangular in form.
These nozzles are located opposite to each other upon the periphery of the section,
and usually in the same horizontal plane.
To these nozzles may be attached the flue sheets, perforated to receive the flue
pipes, and also provided with holes to receive the bolts by which these sheets are
secured to the outward danges of the nozzles.
The flues are set in these sheets in any ordinary manner.
Chambers are formed at each end of the flues and are arranged in such a manner,
and when water or other cooling liquid is forced into one of the chambers, on one
side of the column, it is caused to pass through one pair of flues to a chamber on the
гр... от

page_text: other side of the column, and from thence back again by the next pair of flues. The
circulation of the water may be preferably further continued by providing additional
flues and chambers, and the water is finally discharged through an exit provided in
the last chamber, through which it is circulated.
Couplings can be used when it is desired to couple by connecting pipes, the
sections (two or more) of the column together, so that the water will flow from one
section through another.
The pipes or flues may be either arranged in pairs, or singly, or in any other
manner desired.
•
By the use of these pipes, the contents of the columns are much reduced in
temperature when they leave it, and the quantity of bi-carbonates produced is largely
increased by the quickening of the process.

page_text: 1, WILLIAM B. COGSWELL, of the City of Syracuse, in the County of Onondaga, and
State of New York, United States of America, Engineer, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention relates to the manufacture of bi-carbonates by the columnar process
and relates to the construction of the column and not to the chemical portion of the
process.
Referring to the accompanying drawings-
Figure 1, is a longitudinal vertical section of one of the horizontal segments of the
column.
Figure 2, a top plan view of same, showing sections of construction at the ends of
the piping systems.
Figure 3, a plan view of the inner face of the pipe heads or flue sheets.
Figure 4, an elevation of the column.
My object is to partially at least cool the liquid contents of the column, or reduce
their temperature so that they leave the column cooler than by the ordinary process
where tubular columns are used without any cooling attachments.
It consists in the use of internal or partly internal and partly external cooling pipes,
with the exterior internal surface of which the hot liquid comes into contact and
which pipes are kept as cool as possible by maintaining a flow of cold water through
them or by any other equivalent means.
I construct my column as follows:-
A represents a section of the column tubular in form and provided with flanges
which are secured to the preceding and following sections, in any ordinary manner,
as the column is built up of successive super-imposed sections until the desired
height is reached.
B. B. are rectangular nozzles formed integral with the body of the column,
opening outward and into the interior of the section, the openings being usually
rectangular in form.
These nozzles are located opposite to each other upon the periphery of the section,
and usually in the same horizontal plane.
C. C. are the flue sheets perforated as at a to receive the flue pipes D. D. and also
provided with holes to receive the bolts by which these sheets are secured to the
outward flanges of the nozzles.
The flues are set in these sheets in any ordinary manner.
E, E', are the covers provided with the partition walls b, b, upon E, and d upon E¹
which walls stand at right angles to the inner faces of the covers, and when placed in
position form the chambers 1. 2. 3. 4 and 5.
F. F¹ are couplings for the inlet and exit pipes for the water or cooling mixture.

page_text: H, H' are couplings which can be used when it is desired to couple, by connecting
pipes, the sections, two or more, of the column together, so that the water will flow
from one section through another.
In figure 4, several sections are shown coupled together, and all taking the water
from a single stand pipe m; e. e representing the connecting pipes and n. n, the exit
pipes.
It is operated as follows-
The water enters the chamber 1 through the coupling F, passes thence through the
flues transversely into the chamber 4, thence through the flues into the chamber 2,
thence across into the chamber 5, and thence across into the chamber 3, from which
it passes out through the coupling F¹.
The drawings show the pipes or flues D, arranged in pairs, but they may be
arranged singly or in any other manner desired.
By the use of these pipes the contents of the columns are much reduced in tempera-
ture when they leave it, and the quantity of bi-carbonates produced is largely increased
by the quickening of the process.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I claim is :-
1. A section for a bi-carbonate column consisting of a body A, nozzles B, flue
sheet C, flues D, cover E, and inlet and exit couplings F, F', constructed and
operating together substantially as shown and described.
2. A bi-carbonate column consisting of a series of super-imposed sections, provided
with transverse flues continuously connected, and having inlet pipes opening into the
flues, and exit pipes coupling the sections together, substantially as described.
Daid this 3rd day of November 1887.
