IMPROVEMENTS IN APPA- BATUS FOR CONSUMING SMOKE APPLICABLE TO STEAM BOILER AND OTHER FURNACES
Year: 1873

page_text: LETTERS PATENT to Valentine Locke Lovibond, of Fulham, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN APPA-
BATUS FOR CONSUMING SMOKE APPLICABLE TO STEAM BOILER AND OTHER
FURNACES."
Scaled the 18th November 1873, and dated the 21st May 1873.
PROVISIONAL SPECIFICATION left by the said Valentine Locke
Lovibond at the Office of the Commissioners of Patents, with his
Petition, on the 21st May 1873.
I, VALENTINE LOCKE LOVIBOND, of Fulham, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR CONSUMING SMOKE APPLICABLE TO STEAM BOILER
AND OTHER FURNACES," to be as follows:-
This Invention relates to apparatus applicable to steam boiler and
other furnaces, whereby a regulated supply of atmospheric air is supplied
directly to and is deflected upon the fire at the rearward end, thus con-
suming the smoke and aiding combustion.
.

page_text: Within the brickwork or metal forming the roof of the furnace is con-
structed a horizontal channel, or a pipe or pipes is or are provided
extending from the front to the required distance towards the rear end.
This channel or pipe or pipes is or are connected with a chamber com-
municating with the furnace, and the air is supplied directly to the
furnace.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Valentine Locke Lovibond in the Great Scal
Patent Office on the 21st November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, VALENTINE
LOCKE LOVIBOND, of Fulham, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of May, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Horself, Her heirs and successors,
give and grant unto me, the said Valentine Locko Lovibond, Her
special licence that I, the said Valentine Locke Lovibond, my executors,
administrators, and assigns, or such others as I, the said Valentine
Locke Lovibond, 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 In-
vention for "IMPROVEMENTS IN APPARATUS FOR CONSUMING SMOKE APPLICABLE TO
STEAM BOILER AND OTHER FURNACES," upon the condition (amongst others)
that I, the said Valentine Locke Lovibond, my executors or adminis-
'trators, by an instrument in writing under my, or their, or one of
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 calender months next and immediately after the date of
the said Letters Patent.
NOW KNOW YE, that I, the said Valentine Locke Lovibond, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, reference being had to the
Figures on the accompanying Sheet of illustrative Drawings and to the
letters of reference marked thereon, that is to say :—
This Invention relates to apparatus applicable to steam boiler and
other furnaces, whereby a regulated supply of atmospheric air is supplied
directly to and is deflected upon the fire at such a position in the
furnace, and in such a direction as to meet and mix with the smoke and
gases given off from the coal or fuel freshly supplied at the mouth of the
furnace, when by the admixture of the fresh air with the devolved smoko
and gases they become ignited, and thereby utilized, and the smoke
consumed without any undue admission of cold air, as is the case with
ordinary furnaces.
Within the brickwork forming the roof of the furnace is constructed
a horizontal channel, or a pipe or pipes is or are provided extending from
the front to the required distance towards the rear end. This channel or
pipe or pipes is or are connected with and is or are employed merely for
the purpose of conducting the atmospheric air to a chamber com-
municating with the furnace, and the air is supplied directly to and is
"deflected upon the fire..
A valve or damper is provided within the chamber, communicating
with the furnace, and is worked or operated by a connecting rod passing
from the front thereto. By this valve or damper the supply of air is
regulated to the greatest nicety without interrupting the necessary
direction of supply, or the supply may be entirely shut off theroby when
not required.
On the accompanying Sheet of Drawings Fig. 1 is a vertical section
illustrating the application of my improvements to the furnace of a
brewer's or distiller's copper or boiler; and Fig. 2, a front elevation.
a represents the copper or boiler; b, the furnace; c, the channel con-
nected with the chamber; d and e, the brickwork in which the copper
or boiler is set.

page_text: "
The roof of top of the furnace marked g is of fire-brick construction
or fire-lump," and within the brickwork there is the air passage or
channel c, and at the end of the passage a hinged valve or damper h,
which by means of the rod i and set screw or lever k can be so moved as
to allow more or less air to pass to the chamber d, and thence to the
furnace, or entirely shut off the air, as may be required; andit is
evident that a pipe or pipes may be used instead of the channel or
passage c, as shown. :
And fourthly. Its adaptability to all kinds of furnaces.
Having thus described the nature of my said Invention, I claim, the
improvements in apparatus for consuming smoke applicable to steam
boiler and other furnaces, substantially as herein described and illus-
trated on the accompanying Drawings.

In witness whereof, I, the said Valentine Locke Lovibond, have 2
hereunto set my hand and seal, this Twenty-first day of
November, in the year of our Lord One thousand eight hundred
and seventy-three.
