IMPROVEMENTS IN STEAM BOILERS
Year: 1855

page_text: LETTERS PATENT to Anatole Bère, Government Mining Engineer, of Lille,
France, and of 4, South Street, Finsbury, London, for the Invention of
"IMPROVEMENTS IN STEAM BOILERS."
Sealed the 18th September 1855, and dated the 30th March 1855.
PROVISIONAL SPECIFICATION left by the said Anatole Bère at the
Office of the Commissioners of Patents, with his Petition, on the
30th March 1855.
I, ANATOLE BÈRE, Government Mining Engineer, of Lille, in the Empire
of France, and of 4, South Street, Finsbury, London, do hereby declare the
nature of my Invention for "IMPROVEMENTS IN STEAM BOILERS" to be as follows,
that is to say:
My Invention consists in the adaptation to steam boilers, either cylindrical
or tubular, of a metallic diaphragm and tube, by which the heating surface is
increased to a great extent, producing thereby a larger amount of steam with
the same quantity of fuel.
The Figures 1, 2, 3, 4, 5 & 6 of the accompanying Drawing represent two
boilers, one cylindrical and the other tubular; a metallic diaphragm separates
the two apparatus in such a manner that their communication only takes
place through the metal tube T, T, placed on the side at back of the boiler,
and on the other side plunging into the fore part of the apparatus, but much
below the usual water level.
The feeding water being forced in at the lower part e, e¹, B, of the boiler, does
not reach the other portion A, e, e', where the steam is obtained by passing

page_text: through the tube T, T, after having filled entirely the part e, e¹, B; therefore
the part A, e, e', of the boilers is fed with water sent into the part e, e, B, and
as this latter is always full of water it will be heated externally by the com
bustion taking place in the fire-place in all the extent of the boiler. The
fore part A, e, e', of the boilers, under or into which is placed the fire-place, is
fed by water raised to a high temperature, and that water reaching it is heated
while passing the part e, e', B.
Figures 7 & 8 represent a smoke chest placed in the interior of the boiler,
and the plate receiving the tubes is much larger, without the external diameter
of the cylinder being increased, which permits the tubes to extend nearly the
whole length of the apparatus.
Figure 9 represents the Invention applied to the boiler of a locomotive.
On the part g, c, of the smoke chest receiving the tubes, a cylinder g, h, and
a smoke chest, or cylinder m, n, are placed close to the side P, P, of the
cylindrical envelope...
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Anatole Bère in the Great Seal Patent Office on the
29th September 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANATOLE
BERE, Government Mining Engineer, of Lille, France, and of 4, South Street,
Finsbury, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of March, 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 me, the
said Anatole Bère, Her special licence that I, the said Anatole Bere, my
executors, administrators, and assigns, or such others as I, the said Anatole
Bère, 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 of "IMPROVEMENTS IN
STEAM BOILERS," upon the condition (amongst others) that I, the said Anatole
Bère, by an instrument in writing under my hand and seal, 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

page_text: 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. Anatole 'Bère; dó hereby declare the
nature of my said Invention; and in what manner the same is to be per-
formed; to be particularly described 'and' ascertained in and by the following
statement thereof, reference being had 'to the Drawing hereto annexed, and to
the figures and letters marked thereon, that is to say:
My Invention consists in the application of a feed pipe and diaphragm to
ordinary cylindrical and tubular boilers, by which means, in combination with a
peculiar arrangement of furnace and smoke box or heating chamber, I increase
the heating surface, and thereby obtain a larger amount of steam than hereto-
fore with the same quantity of fuel:
Mer
Figure l'on the annexed Sheet of Drawings represents a longitudinal section
of my improved 'steam boiler; composed of sheet iron or other suitable metal:
e, e, represents the metallic diaphragm, placed within the boiler, about one
third of its length from the furnace; T is à feed pipe, of copper or other metál
which, passing externally from the part B of the boiler, over the diaphragm,
enters the fore boiler A, and extends nearly to the bottom its object is 'to
supply the fore boiler with water. Figures 2 and 3'are sectional views of the
same. Figure 4 shews a modification of the above arrangement; in which the
furnace is placed in the interior of the boiler. Ordinary fire" tubes" for-heating
the water are also placed in the interior of the-boiler, their ends being fixed to
the boiler and to the furnace. Figures 5 and 6 are sectional views of the same.
Figure 7 represents a boiler in which I extend the heating's surface by
forming a heating chamber or smoke box at the end of the furnace, and
to which chamber tubes are attached, as represented. Figure 8 is a section
through x, y, of Figure 7.
Figure 9 shews the application of my improvements to the boilers' of loco
motives; in which-p represents the feed pipe of the fore boiler; c, g, h, m, n,
the heating chamber fixed to the ordinary fire box. To this heating chamber
are attached fire tubes in the usual manner. e represents the diaphragm.
Figure 10 is another view of a locomotive steam boiler, in which the fore
boiler is supplied with a steam dome D: A, E, enlarged fire box; C, B, the
diaphragm.
The water being

forced into the lower part of the boiler e, e', B, until it is completely filled,
then enters the other portion or fore boiler A, e, e', by passing through the feed
pipe T, which forms the only communication. It will thus be seen that the
fire boiler A, e, e, is fed by the excess of water in the boiler e, e¹, B, and which

page_text: has been previously heated by the furnace. This improved boiler possesses
the advantage of containing in a given capacity a much greater quantity of
water than ordinary boilers, also of presenting a much larger heating surface.
It will be obvious that by feeding the fore boiler A, e, e, in the manner before
described, the level of the water can be maintained at any desired height.
The principal advantages attending these improvements are the following:-
First, the fore boiler A, e, e¹, under which is placed the furnace, being fed
with water raised to a high temperature in the boiler e, e¹, B, there is less
danger of the tension of the steam being lessened by the feed water, as
frequently takes place in ordinary steam boilers.
Secondly, the fore boiler A, e, e', where the steam is generated, containing
but a small quantity of water, it will be rapidly raised to a high temperature.
Lastly, by placing a heating chamber or smoke box at the end of the furnace,
as represented in Figures 7 and 8, and by increasing the number of fire tubes,
I obtain a greater amount of heating surface. These improved boilers may be
furnished with safety valves, &c. in the ordinary manner.
Having now described and particularly ascertained the nature of the
Invention, and the manner of performing the same, I wish it to be understood
that I do not restrict myself to the precise details or arrangements herein
contained; but what I claim is,―
First, the general arrangement and construction of steam boilers, as herein
before described, and referred to in the several Figures of the Drawing.
Second, the employment of a feed pipe and diaphragm or partition in
ordinary cylindrical and tubular boilers, in the manner and for the purposes
herein-before described, and represented in Figures 1, 2, 3, 4, 5, 6, 7, 8, 9, and
11 of the annexed Drawing.
Third, the employment of a heating chamber or smoke box at the end of
the furnace in conjunction with the diaphragm and feed pipe, for the purpose
of increasing the heating surface of locomotive or other steam boilers, as
herein-before described, and referred to in Figures 7, 8, and 9 of the annexed
Drawing.
