Sealed the 26th July 1859, and dated the 28th January 1859.
PROVISIONAL SPECIFICATION left by the said Ignazio Zacheroni at the
Office of the Commissioners of Patents, with his Petition, on the
28th January 1859.
I, IGNAZIO ZACHERONI (Native of Italy), residing at Liverpool, in the
County of Lancaster, Artist, do hereby declare the nature of the said
Invention for "AN IMPROVED MODE OR METHOD OF PREVENTING THE ESCAPE OF
SMOKE INTO THE ATMOSPHERE, AND IN THE CONSTRUCTION OF CHIMNEY 'POTS' OR
⚫ TOPS' FOR CURING SMOKY CHIMNEYS," to be as follows:-
I prevent the smoke arising from the furnaces and other fires in manu-
factories and large works from diffusing itself into the air, by completely
covering or closing up the chimney at the top or elsewhere, as most con-
venient; below that covering attaching one or more tubes or flues opening
into the chimney, and carrying them downwards near to the bottom of the

page_text: same, the smoke will ascend the chimney, pass down the tubes or flues, which
have valves opening one way only, and shut itself into a compartment at the
bottom, and be there deposited; the substance deposited can be used as a
fertelizer. I prevent back draughts, and cure smoky chimneys, by dividing
the chimney a certain length downwards from the top and the "pots or
"tops" into four compartments, so that in whatever way the wind blows, three-
fourths of the whole area will allow of free vent.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Ignazio Zacheroni in the Great Seal Patent Office on the
28th July 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, IGNAZIO
ZACHERONI (Native of Italy), residing at Liverpool, in the County of Lancaster,
Artist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of January, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Ignazio Zacheroni, Her special licence that I, the said Ignazio Zacheroni,
my executors, administrators, and assigns, or such others as I, the said
Ignazio Zacheroni, 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
IMPROVED MODE OR METHOD OF PREVENTING THE ESCAPE OF SMOKE INTO THE
ATMOSPHERE, AND IN THE CONSTRUCTION OF CHIMNEY POTS OR TOPS FOR CURING
SMOKY CHIMNEYS," upon the condition (amongst others) that I, the said
Ignazio Zacheroni, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Ignazio Zacheroni, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following,
statement (that is to say):-
My improved mode or method of preventing the escape of smoke into the
atmosphere consists in constructing the chimney without an opening at the top,
in two or more shafts, to allow the smoke to ascend one or more, and descend
by the others, which have valves opening one way, so that the smoke cannot
return. These downward shafts terminate in large chambers or compart-
ments where the smoke will be deposited as soot, the gases that have not
lodged being returned to the furnaces or fires for combustion; the deposit can
be used as a fertilizer.
I cure smoky chimneys by constructing the "pots" or "tops" (and in some
cases part of the chimney downwards from the top) into two or more shafts or
compartments, with wind guards so placed that back draughts are entirely
prevented, and free vent for the smoke maintained. But my improvements
for curing smoky chimneys will be better understood, reference being had to
the Drawings accompanying this, and to the letters of reference thereon; in
all the views the same letters represent the same parts.
Fig. 1 is a perspective view, Fig. 2 a sectional elevation, and Fig. 3 a
transverse section at A, B; the chimney top shewn is divided into four shafts
or compartments, which are represented by a, a, a, a; b, b, b, b, the dividing
plates or partitions; c, the height, being a small opening; d, d, d, the frame
of the "top" e, e, e, the wind guard, being a coating or covering larger than
the frame or side, and leaves (in the form shewn) eight openings represented
by ffff, allowing the smoke to pass outwards, as indicated by the arrows.
Wind blowing into any of these openings, or at the top, will pass outwards at
those below or above, as the case may be, instead of causing a back draught,
or driving the smoke down the chimney. It can be made of terra cotta, iron,
or any substance suitable.
Having now described the nature of my said Invention, and the manner in
which it may be carried out, I would have it understood that I do not confine
myself to the details laid down, as such may be varied without departing from
the general principle; but what I claim is,-
<
Firstly, constructing chimneys with covered tops in two or more shafts or
spaces in the form of a syphon or syphons, ending in chambers or compart-
ments, with or without apertures for carrying the gases not deposited back to
the furnace or fires for combustion for the purpose set forth.
And, secondly, the arrangement or construction of the chimney "pot" or
top," as represented with two or more shafts or spaces in connection with

page_text: dividing the chimney a certain length downwards or otherwise for the purpose
set forth.
In witness whereof, I, the said Ignazio Zacheroni, have hereunto set my
hand and seal, this Twenty-seventh day of July, in the year of our Lord
One thousand eight hundred and fifty-nine.
