Year: 1830

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SETH
SMITH, of Wilton Crescent, in the Parish of Saint George, Hanover Square,
in the County of Middlesex, Builder, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Fourteenth day of September, in the first year of His
reign, did, for Himself, His heirs and successors, give and grant unto me, the
said Seth Smith, His especial licence that I, the said Seth Smith, my
executors, administrators, and assigns, or such others as I, the said Seth
Smith, my executors, administrators, 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 "CERTAIN IMPROVEMENTS IN CHIMNIES FOR DWELLING AND OTHER HOUSES AND
BUILDINGS;" in which said Letters Patent is contained a proviso, obliging me,
the said Seth Smith, by an instrument in writing under my hand and seal,
particularly to describe and ascertain the nature of my said Invention, and in
what manner the same is to be performed, and to cause the same to be
enrolled in His said Majesty's High Court of Chancery within two calendar
months next and immediately after the date of the said 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
Seth Smith, do hereby declare the nature of my said Invention to con-
sist, first, in lining chimmies for dwelling and other houses and buildings with
metallic tubes or linings; and, secondly, in a damper or draft regulator at the
bottom of the chimney, which serves the purpose of a fire board to prevent
back draft when the fire is out. And in further compliance with the said
viso, I, the said Seth Smith, do hereby describe the manner in which
Invention is to be performed, by the following description thereof, reference
being had to the Drawing annexed, and to the figures and letters marked
thereon, that is to say: -
DESCRIPTION OF THE DRAWING.
pro-
my said
Fig. 1 is an elevation in section of a stack of chimnies in a dwelling-house,
lined with metal tubos, and thus shewing my first improvement. Figures
2, 3, 4, 5, and 6 are Drawings to a larger scale, showing the several pieces of
tubing by which I obtain the various directions and turns in the chimics
necessary for such a stack as aforesaid. Figure 7 is a plan of the general
tubing. The tubes here represented are supposed to be made of cast iron, and
fitted together by means of a flange, lip, or rim, as shewn in the Drawing.
Figüro 8 is a front view iii section of my damper or draft regulator in its
position in the chimney and firo-place. A, 13, are two cones imited by flanges
at their basis, tie upper one being furnished with a lip or gutter C, C, for the
Bottom of the chimney lining to shut iiito; D is a circular ring or plate of iroii,
on-which I raise the first piece of metal tube ör liniiig, and which I therefore
feall the starting plate; E is a bar of iroil, furnished with two pullies F, F, over
which pass the two chains G, G, thus supporting the double cone or damper
by one end, and by the other the balanco weight II. It will be seen by this
árrangement, that when tlie balance weight II is raised, the double cone or
damper will descend, thus opening a greater dr less passage for the air up the
chimnoj; while, 'on the contrary, if kept in the position shewn in tliis Figure,
and fastened there by the nut K, no air can pass up or down the chimney,
When the passage for the draft is openoil to its greatest extent, the damper
will assume the position shewn by the dotted lines in this Figure. Figure 9 is
à side view in section of my damper or draft regulator in its position in the
chimney and fire-place. In this Figure it is shown open, while the dotted line
shews its closed position. Figure 10 is a plan of the starting plate D, and
Figure 11 is its section. Figure 12 is the plan of the cross or supporting
bar E, and Figure 13 is its section. It will be observed, that when the damper
is used, it is necessary to cast a recess in the first piece of tubing or lining abovo
the starting plate to receive the ends of the cross bar as at 1, J, Figure 14.

page_text: Of this first piece of tubing, Figure 15 is the plan, Figure 16 is the plan, and
Figure 17 the section, of the double cone damper. Figure 18 is the section of
the nut K. Figure 19 is a separate drawing of the balance weight If, and the
rol by which it is connected with the chains G, G, shewn within the nut K. The
several pieces as they are drawn separately are each marked with a letter, which
refers to the piece as it is united with others in Figures 1, 8, and 9. Figure 20
is a plan of a fire place or opening for a grate or stone prepared to received my
damper.
Now, whereas I claim as my Invention the two improvements aforesaid, (that
is to say,) the lining of chimnies for dwelling and other houses and buildings
with metallic tubes or linings in manner aforesaid, and the damper or draft
regulator, herein-before described; and such my Invention being to the best
of my knowledge and belief entirely new, and never before used within that
part of His said Majesty's United Kingdom of Great Britain and Ireland
called England, His said Dominion of Wales, or Town of Berwick-upon-
Tweed, I do hereby declare this to be my Specification of the same, and that I
do verily believe this my said Specification doth comply in all respects fully
and without reserve or disguise with the proviso in the said herein-before in
part recited Letters Patent contained; wherefore I do hereby claim to main-
tain exclusive right and privilege to my said Invention.
In witness whereof, I, the said Seth Smith, have hereunto set my hand
and seal, this Sixth day of November, in the year of our Lord One
thousand eight hundred and thirty.
Signed, sealed, and delivered in the
presence of
CHARLES P. BARTLEY,
