County of Middlesex, Water Filter Manufacturer, for the Inven-
tion of "IMPROVEMENTS IN THE TREATMENT OF NOXIOUS VAPOURS, AND
1.
PROVISIONAL SPECIFICATION left by the said Frederick Lipscombe at
the Office of the Commissioners of Patents, with his Petition, on
the 16th August 1872.
I, FREDERICK LIPSCOMBE,. of 233, Strand, in the County of Middlesex,
Water Filter Manufacturer, do hereby declare the nature of my said
Invention for "IMPROVEMENTS. IN THE TREATMENT OF NOXIOUS VAPOURS AND
IN APPARATUS OR APPLIANCES IN CONNECTION THEREWITH," to be as follows:—
. I compel the salt fumes which emanate; from a pottery kiln during
the. salt glazing process to pass in the midst of a shower of water,.
whereby they become condensed and prevented from polluting the
atmosphere.
In carrying out my Invention I connect the chimney of a pottery
kiln with one or more condensing flues, through which flues when the

page_text: said chimney is wholly or partly closed smoke must pass to the outer
air, and while so passing through the said flues during the salt glazing
process I cause a shower of water to flow in the midst of the smoke,
thereby condensing the salt fumes, the liquid falling into a receptacle
below. The said shower of water may be produced in various ways, as
for example, by having a cistern with a perforated bottom fitted inside
the flue above the inlet of the salt smoke or fumes from the kiln, so as
to allow the water to fall down the flue and through the salt smoke in
the form of a shower. Or a perforated tray may be substituted for the
cistern, on to which water may be allowed to flow from a pipe, or one or
more jets of water connected with pipes may be situated in any part of
the fluo which will enable the water to be dispersed in the form of a
shower into the salt smoke or fumes as they enter or pass along the
flue. The condensed salt vapour may by subsequent evaporation or
other treatment be utilized for commercial purposes. The said con-
densing flue or flues may be in connection with one or more kilns, and
the salt fumes which emanate from them be condensed in the manner
before mentioned as occasion may require.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Lipscombe in the Great Scal Patent 2
Office on the 13th February 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
LIPSCOMBE, of 233, Strand, in the County of Middlesex, Water Filter
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of August, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Frederick Lipscombe, Her
special license that I, the said Frederick Lipscombe, my executors,
administrators, and assigns, or such others as I, the said Frederick
Lipscombe, my executors, administrators, or assigns, should at any
tinio agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great :

page_text: Britain and Ireland, the Ohannel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN THE TREATMENT OF NOXIOUS VAPOURS AND IN APPARATUS
OB APPLIANCES IN CONNECTION THEREWITH," upon the condition (amongst
others) that I, the said Frederick. Lipscombe, my executors or adminis-
trators, by an instrument in writing under my hand and scal, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to
be filed in the Great Scal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
"
NOW KNOW YE, that I, the said Frederick Lipscombe, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawings, and to the letters and figures, marked. thereon, that is to
say:
My said Invention consists in compelling the salt fumes which
emanate from a pottery kiln during the salt glazing process to pass
in the midst of a shower of water, whereby they become condensed and
prevented from polluting the atmosphere.
In carrying out my Invention, I connect the chimney or upper part
of a pottery kiln by means of branch flues with one or more condensing
flues through which latter fluos, when the chimney of the kiln is wholly
or partly closed, smoke must pass to the outer air, and while so passing
through the said condensing flue or flues during the salt glazing process
I cause a shower of water to flow in the midst of the smoke, thereby
condensing the salt fumes, the-liquid falling into a receptacle below.
The said 'shower of water may be produced in various ways, as for
example, by having a cistern with a perforated bottom fitted inside the
condensing fluc above the inlet of the salt smoke or fumes from the
kiln, so as to allow the water to. fall down the flue and through the
salt smoke in the form of a shower. Or a perforated tray may be
substituted for the cistern on to which water may be allowed to flow
from a pipe, or one or more jets of water connected with pipes may
be situated in any part of the condensing fluc,.which will enable the
water to be dispersed in the form of a shower into the salt smoke or
fumes as they enter or pass along the flue. The condensed salt vapour
may by subsequent evaporation or other treatment be utilized for
commercial purposes. The said condensing flue or flues may..bc.in.

page_text: connection with one or more kilns, and the salt fumes which emanate
from them be condensed in the manner before mentioned as occasion
may require.
And in order that my said Invention may be fully understood I shall
now proceed more particularly to describe the same, and for that
purpose shall refer to the annexed Drawing which represents in partial
section and elevation the application of my Invention to two ordinary
pottery kilns.
A and B are the two kilns in connection with one condensing flue C;
the connection between the kiln A and the flue C is shewn closed by
the damper D; the damper E on the top of that kiln is shewn open;
these two dampers D and E have each an arm which is capable of
moving freely in a slot in the rod F, so that when the rod is moved
upwards or downwards the damper connected therewith that was
previously closed then opens, and that also connected therewith that:
was previously open then closes, the rod being thus made to work both
dampers simultaneously through pressing upon the arm of each damper.
The dampers may be opened or shut separately if desired by each being
provided with a sliding rod of its own, but I prefer that one rod should
work both dampers at the same time.
In the Drawing the kiln B is shewn in communication with the con-
densing flue C; during the salting process the damper G is shewn open,
while the damper H at the top of the kiln is shown closed, both dampers
have each an arm which are worked by means of a sliding rod I in the
manner before described. I do not confine myself to this mode of
working the dampers, as it is obviously capable of several modifications,
but I find this method answers the purpose intended.
The salt smoke or fumes are represented in the Drawing as carried by
the draught out of the kiln B during the salting processes into the
flue C into the midst of a shower of water, which is supposed to have 3
fallen from a cistern or tray K fitted into the flue and having its bottom
perforated, and which has been supplied with water previous to or at
the time of or shortly after the commencement of the salting process by
turning a tap opening a valve or other contrivance in the supply pipe J,
or otherwise opening a communication between the said perforated 3
cistern or tray, and another cistern containing water or with a force
pump; the effect of the shower of water upon the salt smoke or fumes
being to condense them into a liquid which falls with the water to the

page_text: lower part of the flue C, whence it is withdrawn in any convenient
manner; the uncondensed coal smoke and uncondensed salt smoke or
fumes, if any, pass out of the flue O by a lateral passage in the direction
of the arrows into the open air. When the salting process is completed
the rod I may be drawn down, thereby closing the damper G and
opening the damper H, thus restoring the direct draught out of the top
of kiln chimney, as shewn in the kiln A.
Having now described' and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured to
me by the herein-before in part récited Letters Patent is,-
First. The condensation of the salt smoke or fumes from pottery
kilns by means of a shower of water substantially as herein-before
described.
Second. The combination of one or more pottery kilns with a
condensing flue through which a shower of water is caused to fall sub-
stantially as and for the purpose herein-before described.
In witness whereof, I, the said Frederick Lipscombe, have to this
my Specification set my hand and seal, this Eleventh day of
February, One thousand eight hundred and seventy-three.
