IMPROVEMENTS IN DESTROYING THE NOXIOUS VAPOURS ARISING FROM BOILING OIL, BONES, AND OTHER MATTERS IN THE OPEN AIR
Year: 1855

page_text: LETTERS PATENT to Frederick William East, of 214, Bermondsey Street,
Southwark, and John Mills, of William Street, Nent Street, Cobourg
Road, Old Kent Road, for the Invention of "IMPROVEMENTS IN DESTROYING
THE NOXIOUS VAPOURS ARISING FROM BOILING OIL, BONES, AND OTHER MATTERS
IN THE OPEN AIR."
Sealed the 24th April 1855, and dated the 22nd February 1855.
PROVISIONAL SPECIFICATION left by the said Frederick William East
and John Mills at the Office of the Commissioners of Patents, with their
Petition, on the 22nd February 1855.
We, FREDERICK WILLIAM EAST, of 214, Bermondsey Street, Southwark,
and JOHN MILLS, of William Street, Neat Street, Cobourg Road, Old Kent
Road, do hereby declare the nature of the Invention for "IMPROVEMENTS IN
DESTROYING THE NOXIOUS VAPOURS ARISING FROM BOILING OIL, BONES, AND OTHER
MATTERS IN THE OPEN AIR" to be as follows:-
This Invention consists of a peculiar combination of furnace fire-place and
flues, whereby the noxious vapours from a boiler and the products of combus-
tion from the furnace (which beats the same) are caused, together with a
quantity of air, to pass through a fire, whereby all noxious character of the
vapours passing from the boiler are destroyed. For this purpose the boiler is

page_text: set over or licated by a furnace in the ordinary manner; the boiler is arched
or covered over, but left open in front; from the furnace a flue proceeds to a
chimney or shaft, and from the arch or cover over the boiler a flue is also
conducted to the chimney or shaft, by the draft of which the noxious
vapours rising from the boiler, together with a quantity of atmospheric air, will
pass into the chimney or shaft where there is a fire-place with a constant fire
of well-ignited coke or suitable fuel kept, and through this fire the noxious
and other vapours from above the boiler and from the furnace pass, together
with a quantity of atmospheric air which passes in above the boiler, and also,
when necessary, from a ventilator under the fire-bars of the fire in the
chimney or shaft.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick William East and John Mills in the Great Scal
Patent Office on the 22nd August 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERICK
WILLIAM EAST, of 214, Bermondsey Street, Southwark, and JOHN MILLS, of
William Street, Neat Street, Cobourg Road, Old Kent Road, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of February, in the year of our
Lord One thousand eight hundred and fifty-five, in the eighteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Frederick William East and John Mills, Her special licence, that
we, the said Frederick William East and John Mills, our executors, adminis-
trators, and assigns, or such others as we, the said Frederick William East
and John Mills, our 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, usc, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
DESTROYING THE NOXIOUS VAPOURS ARISING PROM BOLLING OIL, BONES, AND OTHER
MATTERS IN THE OPEN AIR," upon the condition (amongst others) that we, the
said Frederick William East and John Mills, by an instrument in writing
under our hands and seals, or under the hand and scal of one of us, 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.

page_text: exclude air passing, so that in the event of the oil taking fire, not only may the
fire below be removed, but the introduction of air may be cut off, so as
quickly to put out the flames. It is preferred to employ a coke fire under the
boiler a, in which case it is not desirable that the products of combustion
passing therefrom should pass through the additional fire in the furnace or fire-
place c, and therefore in the arrangement shewn there is a flue h, which
passes from the fire-place under the boiler direct to the chimney i. The fluc
d also joins the chimney i, as shown. In place of thus conducting the
products of the two fires separately into the chimney, the flues may be arranged
to conduct the products when burning coal from the fire-place below the
boiler into the ash-pit of the fire at e, taking care that there is a plentiful
supply of air. We would, however, remark that we make no claim to the
conducting the products of one fire through another fire when used separate
from our Invention, which consists of the employment of the second fire as
the means of obtaining draft over a boiler, and destroying the noxious or
objectionable odours of vapours evolved from such boiler.
Having thus described the nature of our said Invention, and the manner
of performing the same, we would have it understood that what we claim is,
the mode herein described of obtaining a draft over a boiler, and of destroying
the noxious odours of the vapours arising from such boiler by means of a fire in
addition to the fire employed for heating the boiler.
In witness whereof, I, the said John Mills, have hereunto set my hand
and seal, this Eighteenth day of August, in the year of our Lord
One thousand eight hundred and fifty-five.
Witness,
S. CARPMAEL.
JOHN MILLS. (L.B.)
