IMPROVEMENTS IN THE CONSTRUCTION OF THE UPPER PARTS OF CHIMNEYS
Year: 1847

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
HUNTON TOWNSEND BISHOP, of Hackney Terrace, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Second day of March
(One thousand eight hundred and forty-seven), in the tenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Samuel Hunton Townsend Bishop, my exors, admors, and
assigns, Her especial licence, full power, sole privilege and authority, that
I, the said Samuel Hunton Townsend Bishop, my exors, adiñiors, and assigns,
or such others as I, the said Samuel 1Tunton Townsend Bishop, my exors,
adiiors, or assigns, should at any time agree with, and no others, from time
to time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN
THE CONSTRUCTION OF THE UPPER PARTS OF CHIMNEYS;" in which said Letters
Patent is contained a proviso that I, the said Samuel Hunton Townsend
Bishop, should cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, by an instru-
ment in writing under my hand and seal, to be iurolled in Her said Majesty's
High Court of Chancery, with six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Hunton Townsend Bishop, do hereby declare that the nature of my
said Invention, and the manner of performing the same, are fully described and
ascertained in and by the following description, reference being had to the
Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say-
The Invention relates to improvements in the construction of chimneys for
the purpose of preventing them smoking; and in order that my Invention
may be fully understood, I will proceed to describe the Drawings, and I have
used the same letters to similar parts wherever they occur.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side view of apparatus made of tin, zinc, or other suitable
material to be affixed to the brickwork of the building, where it is intended
to be used as the upper part of a chimney.
Figure 2 shews a section, and Figure 3 a plan, of the same, in which it will
be seen that there are a series of openings a, a, having shields b, placed internally
and projecting upwards. These projecting pieces may be soldered on or fastened
by any convenient means; and it will easily be understood, by examining the
Drawings, that as the wind enters through the openings a, it will rush up to
the upper part of the apparatus, thereby causing such a draft in the chimney
as to carry away all smoke coming from the fire.
Figures 4, 5, and 6 shows a side view, a section, and a plan of another
form of apparatus, in which the same principle of construction is carried out,
the only difference being in the external form.
Figures 7, 8, and 9 shew a plan, a section, and an end view of another
apparatus, to be affixed in the chimney for the purpose of regulating the draft,
and thus preventing the smoke from descending into the room where the fire
may be situated. This apparatus consists of a series of plates arranged in a
frame, in such manner as to be capable of opening or shutting by a screw
or other suitable means. a, a, is the framing of the apparatus to which the
plates b, b, are affixed; c is the screw for regulating or adjusting the opening
or closing of the plates according to the draft required; d is a spring on to
which the connecting bar e rests, and this spring is affixed to the frame a.
This apparatus is to be placed within and across the opening of the chimney,
in a frame suitably arranged for it to fit in, at such a distance above the fire
as to be within reach, the screw being outside or otherwise, so that the
opening of the plates may be adjusted as required. The form of the plates b
may be varied as shewn by red lines, the object of these plates being to close

page_text: the opening in the chimney when no fire is required, and thus prevent cold
air entering into the room.
Having thus described the nature of the Invention, and the manner of
performing the same, I would remark, that although I have shewn in the
Drawings apparatus applied as a chimney for houses, yet it may be used as a
funnel or chimney for steam boats or any other purpose; and I do not confine
myself to the precise details, so long as the peculiar character of the Invention
be retained, but what I claim is, the apparatus herein described for preventing
chimneys from smoking.
In witness whereof, I, the said Samuel Hunton Townsend Bishop,
have hereunto set my hand and seal, this Twenty-seventh day of
August, in the year of our Lord One thousand eight hundred and
forty-seven
