IMPROVEMENTS IN SMOKE-CONSUMING FURNACES
Year: 1862

page_text: LETTERS PATENT to Marc Antoine François Mennons, of the British and
Foreign Patent Offices, 24, Rue du Mont Thabor, Paris, in the Empire
of France, for the Invention of "IMPROVEMENTS IN SMOKE-CONSUMING
FURNACES." A communication from Bernard Palazot, residing at
Bordeaux (Dent. de la Gironde) in France.
COMPLETE SPECIFICATION filed by the said Marc Antoine François
Mennons at the Office of the Commissioners of Patents, with his
Petition and Declaration on the 28th August 1862, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANÇOIS MENNONS, of the British and Foreign Patent Offices, 24,
Rue du Mont Thabor, Paris, in the Empire of France, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN SMOKE-
CONSUMING FURNACES," (communicated to me by Bernard Palazot, a person
resident at Bordeaux (Dep. de la Gironde) in France), and have petitioned
Her Majesty to grant unto me, my executors, administrators, and assigns, Her
Royal Letters Patent for the same, and made solemn declaration that it is a
communication..
NOW KNOW YE that I, the said Marc Antoine François. Mennons, do
hereby declare that the following-Complete Specification under my hand--and

page_text: seal fully describes and ascertains the nature of the Invention, and the manner
in which the same is to be performed, reference being had to the Figures of
the accompanying Drawing, and to the letters marked thereon, that is to
say:-
This Invention consists in an improved arrangement of certain parts of
steam boiler and other furnaces, by means of which perfect combustion and
complete fumivority are obtained, accompanied in many cases by a considerable
economy of fuel.
The accompanying Drawing represents in cross and longitudinal section,
a boiler furnace comprising the present improvements.
A is a slit aperture formed accross the furnace in front of the grate, and
giving passage to a current of air, the volume and velocity of which are
regulated by the register B; C is a vaulting of refractory clay, which in certain
cases may be replaced by a simple plate. The form of this vault or plate may
be modified so long as its position above the fire-bridge be retained, as seen in
the Drawing, so as to concentrate the heat at the passage of the flame in D, D.
The section of this passage D, D, should be about one-fifth or one-sixth the
surface of the grate. On opening the register B of the furnace, arranged as
above, the atmospheric air is admitted, and flowing over the incandescent
surface of the fuel mingles with the gaseous products of the combustion, which
being thus oxygenised are entirely consumed in their passage under the
vaulting.
Having now described and ascertained the nature of the said Invention and
the manner of carrying it into effect, I declare that I claim the improved
combination of the vaulting or plate C, with the air entry A and register B
applied to boiler and other furnaces, the whole constructed and arranged in
manner and for the purpose, substantially as herein specified and shewn in the
Figures of the accompanying Drawing.
In witness whereof, I, the said Marc Antoine François Mennons, have
hereto set my hand and seal, this Twenty-seventh day of August, in
the year of our Lord One thousand eight hundred and sixty-two.
