IMPROVED APPARATUS FOR TAKING UP THE EMANATIONS AND THE GASES FROM BOILERS
Year: 1864

page_text: LETTERS PATENT to Jean Marius Faget, Architect Engineer, of Bordeaux,
(4, Orleans Street,) in the Department of Gironde, in the Empire of
France, for the Invention of "IMPROVED APPARATUS FOR TAKING UP THE
EMANATIONS AND THE GASES FROM BOILERS."
Sealed the 8th August 1864, and dated the 11th February 1864.
PROVISIONAL SPECIFICATION left by the said Jean Marius Faget at
the Office of the Commissioners of Patents, with his Petition, on the
11th February 1864..
I, JEAN MARIUS FAGET, Architect Engineer, of Bordeaux, (4, Orléans
Street,) in Department of Gironde, in the Empire of France, do hereby
declare the nature of the said Invention for "IMPROVED APPARATUS FOR TAKING
UP THE EMANATIONS AND THE GASES FROM BOILERS," to be as follows:-
This apparatus is composed of a metal or wooden cover or lid of conical form,
covering at the same time the boiler or cauldron in ebullition' and the orifice
of a cylindrical pipe or conduit formed in the interior of the masonry or brick-
work, which pipe opens at its lower end in the ash-pit. The doors of the ash-
pit and fire-place are hermetically closed, so that the combustion forcibly takes
place by the upward draught. To this end the cover or lid is. furnished with
slides which may be graduated at will, or, more simply in practice, the work-
man raises the cover by means of a small wooden wedge inserted-under the
side opposite the orifice of the conduit or by recall screws. A small inclined
circular slab is fitted inside the cover to gather and throw out some products

page_text: the condensation of which is of little importance, and which vary according to
the seasons and the difference of temperature between the vapour and the
exterior air. The absorption of the emanations and gases is by the current,
which, sweeping the surface of the liquid, goes by the pipe into the ash-pit.
The evaporation is singularly favored by this current. In the centre of the
lid on the outside is a ring, in which passes a chain or rope, by which, aided by
a pulley, the cover is raised when it is desired to fill or empty the boiler or to
skim or inspect its contents. ...
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Marius Faget in the Great Seal Patent Office on the
10th August 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
MARIUS FAGET, Architect Engineer, of Bordeaux, (4, Orleans Street,) in
the Department of the Gironde, in the Empire of France, send greeting...
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of February, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Jean Marius Faget, Ier special licence that I, the said
Jean Marius Faget, my executors, administrators, and assigns, or such others
as I, the said Jean Marius Faget, 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 Invention
for "IMPROVED APPARATUS FOR TAKING UP THE EMANATIONS AND THE GASES PROM
BOILERS," upon the condition (amongst others) that I, the said Jean Marius
Faget, my executors or administrators, 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 calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Jean Marius Faget, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following

page_text: statement, reference being had to the Sheet of Drawing hereunto annexed,
and forming part of this my Specification, and to the figures and letters of
reference placed thereon, similar letters denoting similar parts at each of the
Figures respectively.
.
Figure 1 is a front view of the cover or lid of a boiler in position; Figure 2,
top plan view of cover or lid; Figure 3, section at A, B, Figures 2 and 4;
Figure 4, plan view of under side of cover or lid; Figure 5, lifting of
cover or lid by means of screws; and Figure 6, lifting of same by means of
wedges.
This improved apparatus is composed of a metal or wooden cover or lid A
of conical form, covering at the same time the boiler or cauldron in ebullition,
and the orifice of a cylindrical pipe or conduit B formed in the interior of the
masonry or brickwork, and outside the fire shafts or towers, if there are any,
the said pipe or conduit opening at its lower end in the ash-pit. The doors
of the ash-pit and fire-place are hermetically closed, so that the combustion
forcibly takes place by the upward draught exercised in the flue. With this
object the cover or lid is furnished with slides c, which may be graduated at
will, or, more simply in practice, the workman raises the cover by means of
a small wooden wedge, as at Figure 6, inserted under the side opposite the
orifice of the conduit or by recall screws, as at Figure 5. A small circular
inclined slab D is fitted inside the cover to receive and expel some products the
condensation of which is of little importance, and which vary according to the_
seasons and the difference of temperature between the vapour and the exter
air. The absorption of the emanations and the gases is obtained by the current,
which, sweeping the surface of the liquid, goes by the pipe B into the ash-pit,
and the evaporation is singularly favoured by this current. In the centre of
the lid on the outside is a ring, in which passes a chain or rope, by which, aided
by a pulley, the cover is raised when it is desired to fill or empty the boiler
or to skim or ascertain the state of its contents.
In witness whereof, I, the said Jean Marius Faget, have hereunto set
my hand and seal, this Third day of August, in the year of our Lord
One thousand eight hundred and sixty-four.
J. M. FAGET. (L.S.)
