and 18, Rue de la Chaussée d'Antin, Paris, France, Patent Agent,
for the Invention of "A NEW AND IMPROVED BELLOWS FOR FORGES,
FURNACES, OR ANY OTHER WORKS."-A communication from Charles
Alexandre Furon. residing at Belleville, France, Machinist.
Sealed the 5th July 1872, and dated the 24th January 1872.
PROVISIONAL SPECIFICATION left by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition,
on the 24th January 1872.
I, HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent
Offices, 6, Piccadilly, in the County of Middlesex, and 18, Rue de la
Chaussée d'Antin, Paris, France, Patent Agent, do hereby declare the
nature of the said Invention for "A NEW AND IMPROVED BELLOWS FOR
FORGES, FURNACES, OR ANY OTHER WORKS,"" communicated to me by Charles
Alexandre Furon, a person resident at Belleville, France, Machinist, to
be as follows:-

page_text: bellows for forges, furnaces, or any other works by means of which a
more powerful blast is obtained than by the bellows now in use, the
diameter of the air feeding mouth being equal and even inferior to the
air feeding mouth of ordinary bellows.
The main improvement consists to give to the air feeding mouth a
diameter twice as large as that of the outlet mouth, and to place the
said outlet mouth on one of the sides of the casing or chamber of the
bellows instead of placing it directly opposite the feeding mouth as is
usually done, so that the upsetting of the air be slanting.
Another improvement consists to set the helix, of which the blades
are of sheet iron, on to a steel shaft in the middle of which is keyed the
driving pulley, so that the friction be less and the wearing out equal;
and to keep in place the helix by means of bronze rings or hoops passed
through by the driving shaft, moveable on said shaft and regulated by
tightning or adjusting screws, so that the helix can be adjusted and
kept in place firmly in its casing or chamber of the bellows without
rubbing against the inner sides of the said casing or chamber, which
thus prevents the breaking or destroying of the blades of the helix.
.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henri Adrien Bonneville in the Great Seal Patent
Office on the 10th July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 6, Picca-
dilly, in the County of Middlesex, and 18, Rue de la Chaussée d'Antin,
Paris, France, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of January, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-fifth
year of. Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Henri Adrien Bonneville, Her special licence
that I, the said Henri Adrien Bonneville, my executors, administrators,
and assigns, or such others as I, the said Henri Adrien Bonneville, my
executors, administrators, and assigns, should at any time agree with, and

page_text: 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 "A NEW AND IM-
PROVED BELLOWS FOR FORGES, FURNACES, OR ANY OTHER WORKS," Communicated
to me by Charles Alexandre Furon, a person resident at Belleville,
France, Machinist, upon the condition (amongst others) that I, the said
Henri Adrien Bonneville, my executors or administrators, by an instru-
ment 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 Henri Adrien Bonneville, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in the following statement :-
This Invention relates to improvements in bellows or ventilators or
fan blowers for forges, furnaces, or any other works by means of which
a more powerful blast is obtained than by the bellows or blowers now in
use, the diameter of the air feeding mouth being equal and even inferior
to the air feeding mouths of ordinary bellows.
The main improvement consists to give to the air feeding mouth a
diameter twice as large as that of the outlet mouth, and to place the
said outlet mouth on one of the sides of the casing or chamber of the
blower directly instead of placing it opposite the feeding mouth, as is
usually done, so that the upsetting of the air be slanting.
Another improvement consists to set the helix, of which the blades are
of sheet iron, on to a steel shaft in the middle of which is keyed the
driving pulley, so that the friction be less and the wearing out equal;
and to keep in place the helix by means of bronze rings or hoops passed
through by the driving shaft, moveable on said shaft and regulated by
tightening or adjusting screws, so that the helix can be adjusted and
kept in place firmly in its casing or chamber of the blower without
rubbing against the near sides of the said casing or chamber, which thus
prevents the breaking or destroying of the blades of the helix.
Having thus described the said Invention I will now proceed to specify

page_text: the same more particularly, reference being had to the accompanying.
Drawings, in which Fig. I. is a longitudinal vertical elevation of the said
blower or ventilator; Fig. II. a plan view, and Fig. III. an end view of
the same; Fig. IV. a transverse section through the line. A, B, Fig. I.;
Fig. V. an end view of the casing. In these Figures similar letters of
reference indicate corresponding parts.
A is the frame; B, B, are two uprights in which are mounted the
bearings of the steel shaft C of the blower; D is the driving pulley fixed
to the said shaft by means of a screw; E, E, are adjustable bronze rings
on the said steel shaft; F, F, are adjusting or tightening screws by
means of which the adjustable rings are regulated; G is an abutment
screw designed to prevent friction; H is the casing; I, I, are cast-iron
blades of helix or fan blower; J is the inlet mouth; K is the outlet.
Having thus described the said Invention and the manner in which
the same is to be carried into effect, I wish it to be understood that I do
not intend to confine myself strictly to the precise details above enu-
merated, as the same admit of variation without departing from the
principle of the Invention; but what I claim is,--
First. Forcing atmospheric air obliquely out of the blower by means
of an orifice placed on one side of the casing of the blower.
Secondly. The construction and arrangement of the sheet iron blades
of the helix or blower mounted on a steel shaft, and the combination
of the same with a driving pulley mounted on the shaft.
Thirdly. The adjusting rings, having for object to fix the helix or
blower firmly in its place.
In witness whereof, I, the said Henri Adrien Bonneville, have
hereunto set my hand and seal, this Eighth day of July,
in the year of our Lord One thousand eight hundred and
seventy-two.
