Year: 1854

page_text: LETTERS PATENT to John Manley, of Chacewater, in the County of Corn-
wall, Mine Agent, for the Invention of "AN IMPROVEMENT IN VENTILATION,
AND IN TREATING SMOKE SO AS TO PREVENT THE ASCENT OF THE DENSER
PARTICLES THEREOF INTO THE ATMOSPHERE."
Sealed the 20th October 1854, and dated the 4th May 1854.
PROVISIONAL SPECIFICATION left by the said John Manley at the Office
of the Commissioners of Patents, with his Petition, on the 4th May
1854.
I, JOHN MANLEY, of Chacewater, in the County of Cornwall, Mine Agent,
do hereby declare the nature of the said Invention for "AN IMPROVEMENT IN
VENTILATION, AND IN TREATING SMOKE SO AS TO PREVENT THE ASCENT OF THE
DENSER PARTICLES THEREOF INTO THE ATMOSPHERE," to be as follows:-
My Invention consists in leading air from any place requiring to be ventilated,
or the products of combustion, into a bent pipe, tube, or flue; near the top of the
bend, and on the side opposite to that at which the air or smoke and products
of combustion enter, I introduce a stream of water, and cause it to descend
the pipe through a rose or distributor. The air or smoke will be drawn over
by the descending streams of water, will be carried down with the water, and,
in the case of smoke and the products of combustion, will have the denser
particles thereof either carried away entirely by the water or collected in a

page_text: suitable receptacle, while such portions as may not be collected may be carried
directly into drains or allowed otherwise to pass off. By this means no blacks
or other like impurities arising from imperfect combustion can escape into the
atmosphere.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Manley in the Great Seal l'atent Office on the 4th
November 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MANLEY, of Chacewater, in the County of Cornwall, Mine Agent, send greeting.
.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the. Fourth day of May, in the year of our Lord One.
thousand eight hundred and fifty-four, in the seventeenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Manley, Her special licence that I, the said John Manley, my executors,
administrators; and assigns, or such others as I, the said. John Manley, my
executors, administrators, and assigns, should at any time 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 Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "AN IMPROVEMENT IN VENTILATION, AND
IN TREATING SMOKE SO AS TO PREVENT THE ASCENT OF THE DENSER PARTICLES
THEREOF INTO THE ATMOSPHERE," upon the condition (amongst others) that I,
the said John Manley, by an instrument in writing under my hand and seal,
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 Seal Patent Office within six calendar months next_and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Manley, 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
thereof; reference being had to the Drawings hereunto annexed (that is to
say)
My Invention consists in leading air from any place requiring to be venti-
lated, or smoke and the products of combustion, into a bent pipe, tube, flue,
or shaft; near the top of the bend, and on the side opposite to that at which the

page_text: air or smoke and products of combustion enter, I introduce a stream of water,
and cause it to descend the pipe, tube, flue, or shaft through a rose or distributor.
The air or smoke will be drawn over by the descending streams of water, will
be carried down with the water, and, in the case of smoke and the products of
combustion, will have the denser particles thereof either carried away entirely
by the water or collected in a suitable receptacle, while such portions as may
not be collected may be carried directly into drains or allowed otherwise to pass
off. By this means no blacks or other like, impurities arising from imperfect
combustion can escape into the atmosphere.
The Drawing annexed represents a sectional elevation of an arrangement
suitable for treating smoke according to my Invention, as applied to a cement
kiln. A, A, is the kiln; B is the furnace door; and C is the kiln door. D is
the flue leading from the kiln; E is a horizontal flue, which connects the flue
D with the water shaft F; G is a cistern for supplying water to this shaft;
and H is a pipe with a rose, by which the water is introduced in a shower.
I, I, are sloping boards or shelves fitted to the sides of the shaft F, for the
purpose of spreading or distributing the water falling on them. J is a tank
or receptacle at the bottom of the shaft F, which serves to retain the matters
intercepted by the falling shower of water; and K is a drain or conduit
through which the superfluous water is conducted to a sewer. L is a pipe with
a bell mouth M, through which the combustible portions of the purified smoke
return to the furnace, to be there consumed. This pipe may be dispensed with,
and the purified smoke allowed to pass off through the drain or conduit K, or
it may escape into the atmosphere. The matters collected in the tank or
receptacle J may be periodically removed from it, and applied to any purposes
for which they may be suitable. The foregoing description will be sufficient to
enable my Invention to be applied to furnaces or fire-places of any construction,
the smoke of which is required to be purified.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, as an improvement in ventilation, the employment of a stream or
streams of water, introduced in a shower and descending through a pipe, tube,
or shaft, communicating with the place to be ventilated, so as to produce a
current of air from such place, and thus effect the removal of vitiated air
therefrom.
And second, as an improvement in treating smoke so as to prevent the ascent
of the denser particles thereof into the atmosphere, the employment of a stream.
or streams of water introduced in a shower, and descending through a pipe, tube,

page_text: or flue, communicating with the furnace or fire-place wherein such smoke is
produced, for the purpose of purifying such smoke by intercepting and absorb-
ing. the denser particles thereof, whether such smoke so purined is allowed to
escape into the atmosphere, or is conducted into a drain or sewer with the
superfluous water, or whether it is returned to be consumed in the furnace or
fire-place, as herein-before described.
In witness whereof, I, the said John Manley, have hereunto set my
hand and seal, this Thirty-first day of October, One thousand eight
ing. the denser particles thereof, whether such smoke so purined is allowed to
escape into the atmosphere, or is conducted into a drain or sewer with the
superfluous water, or whether it is returned to be consumed in the furnace or
fire-place, as herein-before described.
In witness whereof, I, the said John Manley, have hereunto set my
hand and seal, this Thirty-first day of October, One thousand eight
hundred and nity-four.
JOHN MANLEY. (L.S.)
