Year: 1875

page_text: LETTERS PATENT to Joseph Hookey Tarrant, of the Firm of Tarrant
and Sons, Builders, of Weymouth Street, New Kent Road, in the
County of Surrey, for the Invention of "IMPROVED APPARATUS FOR
THE PREVENTION OF SMOKY CHIMNEYS, APPLICABLE ALSO FOR VENTILATING
DODGES "
Sealed the 26th April 1876, and dated the 27th October 1875.
PROVISIONAL SPECIFICATION left by the said Joseph Hookey Tarrant
at the Office of the Commissioners of Patents, with his Petition,
on the 27th October 1875.
I, JOSEPH HOOKEY TARRANT, of the Firm of Tarrant and Sons,
Builders, of Weymouth Street, New Kent Road, in the County of
Surrey, do hereby declare the nature of the said Invention for
"IMPROVED APPARATUS FOR THE PREVENTION OF SMOKY CHIMNEYS, APPLICABLE
ALSO FOR VENTILATING PURPOSES," to be as follows:
This Invention consists in an improved apparatus for the prevention
of smoky chimneys, applicable also for ventilating purposes.
The following is the manner I propose to construct the said improved
apparatus:-Outside and around a cylindrical or other shaped chimney

page_text: pot I fix vertical tubes opened at the bottom or lower part of the chimney
pot and closed at the top. At a little distance from the closed ends of
the said tubes I form openings which place the tubes in communication
with the inside of the chimney.
The object of the said tubes is to form flues into which the wind will
enter by the openings at the bottom, and come out inside the chimney
by the openings aforesaid, thus causing a strong draught which carries
off the smoke rapidly.
It will be seen that by means of an apparatus constructed as above
the wind however strong, or from whichever quarter it may blow, will 1
serve to increase the draught, and cause the smoke to be quickly carried
away, it being used as the agent for producing the draught.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Hookey Tarrant in the Great Seal Patent
Office on the 27th April 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
HOOKEY TARRANT, of the Firm of Tarrant and Sons, Builders, of
Weymouth Street, New Kent Road, in the County of Surrey, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of October, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Hookey Tarrant, Her special
licence that I, the said Joseph Hookey Tarrant, my executors, admini-
strators, and assigns, or such others as I, the said Joseph Hookey Tarrant,
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
"IMPROVED APPARATUS FOR THE PREVENTION OF SMOKY CHIMNEYS, APPLICABLE
ALSO FOR VENTILATING PURPOSES," upon the condition (amongst others)
that I, the said Joseph Hookey Tarrant, my executors or admini-
strators, by an instrument in writing under my, or their, or one of

page_text: their hands and seals, 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 Joseph Hookey Tarrant, 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 :—
This Invention consists in an improved apparatus for the prevention
of smoky chimneys, applicable also for ventilating purposes.
The following is the manner I purpose to construct the said improved
apparatus-Outside and around a cylindrical or other formed chimney
pot I fix vertical tubes opened at the bottom or lower part of the
chimney pot and closed at the top. At a little distance from the closed
ends of the said tubes I form openings which place the tubes in com-
munication with the inside of the chimney.
The object of the said tubes is to form flues, into which the wind
will enter by the openings at the bottom and come out inside the
chimney by the openings to the inside of the chimney aforesaid, thus
causing a strong draught which carries off the smoke rapidly.
It will be seen that by means of an apparatus constructed as above
the wind however strong, or from which ever quarter it may blow, will
serve to increase the draught, and cause the smoke to be quickly carried
away, it being used as the agent for producing the draught.
Having now described and ascertained the nature of the said Inven-
tion, and incidentally intimated in what manner the same can bo
performed or carried out in practice, I will now proceed, aided by the
accompanying Drawings, to further and particularly describe and ascer-
tain in what manner the same is to be performed or carried out in
practice, that is to say :—―
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an elevation of my improved apparatus; Fig. 2 is a vertical
section; Fig. 3, plan on top; Fig. 4, sectional plan.
In these Figures A represents the main chinney pot; B, the vertical
tubes connected thereto, open at the bottom or lower part, as shewn,

page_text: and closed at the top by cap C; D are the openings in said tubes made
inside of the tubes, and preferably placed between cap C and metal
bands b, b¹, b being outer band that encircles the tubes B, and b' inner
band encircled by the tubes B, which latter serve to hold and strengthen
the apparatus.
The smoke rises in the main chimney A, and passes up into and
through the opening a at top of cap C, the air entering the tubes B at x,
passing out through D, serving to effect this result, as herein-before
described. Should however the force of the wind be such as to blow or
force down the smoke from A, then same passes through the openings D
in tubes B, and out by the openings x at the lower part of the said
tubes.
Having now particularly described and ascertained the nature and
object of the said Invention, and in what manner the same is to be
performed or carried out in practice, I hereby declare that I claim the
Invention of "Improved Apparatus for the Prevention of Smoky
Chimneys, applicable also for Ventilating Purposes," substantially as
same is herein-before set forth and described, wherein the peculiar and
important point is the arrangement of the tubes in communication with
the chimney by means of the main chimney pot, substantially as hercin-
before set forth and described and illustrated by the accompanying
Drawings.
In witness whereof, I, the said Joseph Hookey Tarrant, have here-
unto set my hand and seal, this Twenty-sixth day of April, in
the year of our Lord One thousand eight hundred and seventy-
ciz
