Year: 1844

page_text: STAFFORD, of Grantham, in the County of Lincoln, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Third day of July, in the eighth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Daniel
Stafford, Her especial licence, full power, sole privilege and authority, that I, the
said Daniel Stafford, my exors, adfiiors, and assigns, or such others as I, the
said Daniel Stafford, 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 APPARATUS FOR PREVENTING WHAT IS TERMED SMOKEY
CHIMNEYS OR FLUES, AND FOR THE EXTINCTION OF FIRE IN CHIMNEYS OR FLUES;" in
which said Letters Patent is contained a proviso that I, the said Daniel
Stafford, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be inrolled in Her said
Majesty's High Court of Chancery within 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.

Invention for preventing what are called smokey chimneys. Figure 2 is a section
thereof. Figure 3 is a transverse section; and Fig. 4 is a sectional plan thereof
taken thro' the dotted line A, B. a is the internal chimney pot, or internal part of
the apparatus up through which the smoke proceeds, and the upper part of a
rises considerably above the openings at in the external apparatus c; the
openings at are all round the part a, hence there is free passage for the
external air to pass into the interior of the apparatus b, and the air is guided
upwards by the form of the interior apparatus a. And it will also be seen that
the exterior part c of the apparatus rises to a considerable height above the
upper part of a; hence the currents of air entering at b will rise up through c,
and produce an upward current, and be the means of a constant upward
current in the apparatus a, and in the chimney to which it is applied.
I will now describe the second part of my Invention, which consists in
building within a chimney and near the upper part thereof, a frame with a
door opening downward, and this door, under ordinary circumstances, will remain
open. d is the frame, which is to be built into a chimney, and near the upper
part thereof.
e is a door hinged to the frame, which opens inward and down-
ward, as shown. f is a chain or other suitable means for raising the door at
any time, such chain descending to the lower part of the chimney, and, in case
of fire in the chimney, by closing the door, all draft upwards will be stopped,
and the fire will quickly go out for want of air.
In witness whereof, I, the said Daniel Stafford, have hereunto set my
hand and seal, this Third day of January, in the year of our Lord One
thousand eight hundred and forty-five.
DANIEL (L.S.) STAFFORD.
