IMPROVEMENTS IN APPARATUS FOR SUPPLYING, BLOWING IN, AND EXHAUSTING AIR, PRODUCING DRAFT, AND VENTILATING
Year: 1868

page_text: LETTERS PATENT to Eugene Theodore Noualhier, of Paris, in the
French Empire, Manufacturer, for the Invention of "IMPROVEMENTS
IN APPARATUS FOR SUPPLYING, BLOWING IN, AND EXHAUSTING AIR, PRODUCING
DRAFT, AND VENTILATING."
Sealed the 22nd June 1869, and dated the 30th December 1868.
PROVISIONAL SPECIFICATION left by the said Eugene Theodore
Noualhier at the Office of the Commissioners of Patents, with his
Petition, on the 30th December 1868.
I, EUGENE THEODORE NOUALHIER, of Paris, in the French Empire,
Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR SUPPLYING, BLOWING IN, AND EXHAUSTING AIR,
PRODUCING DRAFT, AND VENTILATING," to be as follows:-
The apparatus consists of a tube which is surrounded or surmounted
by another tube extending round the required portion of the length of the
first tube, and provided with a number of vanes, deflectors, or curved or
other plates, which together with radial or other partitions or plates formi

page_text: air ducts or passages, into and through which air is drawn, and whence it
passes away round the top or end of the inner tube. The parts may be
fixed so that the apparatus may be used in all requisite aspects, positions,
or circumstances. To prevent counter currents a spherical or other cowl
or a dome-shaped cap may be pivoted or hung at the top of the outer
tube, so as to take the required positions or inclinations for this purpose.
The apparatus may be modified by reversing the position or arrangement
of the tubes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Eugene Theodore Noualhier in the Great Seal
Patent Office on the 30th June 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EUGENE
THEODORE NOUALHIER, of Paris, in the French Empire, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of December, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Eugene Theodore Noualhier,
Her special licence that I, the said Eugene Theodore Nouallier, my
executors, administrators, and assigns, or such others as I, the said
Eugene Theodore Noualhier, 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 law-
fully 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 "IMPROVEMENTS IN APPARATUS FOR SUPPLYING, BLOWING IN,
AND EXHAUSTING AIR, PRODUCING DRAFT, AND VINTILATING," upon the con-
dition (amongst others) that I, the said Eugene Theodore Noualhier,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and scals, 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 imme-
diately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Eugene Theodore Noualhier, 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 and by the following statement thereof, reference being had to the
accompanying Drawings, that is to say :-
The apparatus consists of a tube which is surrounded or surmounted
by another tube extending round the whole or a required portion of the
length of the first tube, and provided with a number of vanes, deflectors,
or curved or other plates, which together with radial or other partitions
or plates form air ducts or passages, into and through which air is drawn,
and whence it passes away round the top or end of the inner tube. The
parts may be fixed so that the apparatus may be conveniently used in all
requisite aspects, positions, or places. To prevent counter currents a
spherical or otherwise shaped cowl or a dome-shaped cap may be pivoted
or hung at the top of the outer tube, so as to take the required positions
or inclinations for this purpose. The apparatus may be modified by
reversing the position or arrangement of the tubes.
I may mention that the apparatus is adapted for producing ventilation
by exhausting or extracting noxious or deleterious gases and vapours
from confined or infected places, also for withdrawing the foul atmos-
phere, and admitting fresh air into dwellings, churches, halls, and other
places containing persons, and for producing a satisfactory draft in
furnaces (or elsewhere where required) without counter currents.
The accompanying Drawings represent apparatus constructed accord-
ing to my Invention.
Figure 1 is an elevation, and Figure 2 vertical section of the apparatus,
Figure 3 is a modification shewn in vertical section.
A is a tube, cylinder, or hollow column which enters at its bottom end
into the place to be ventilated, or into the place wherein a draft is to be
obtained; as, for instance, it may be placed in the uptake or chimney of
a furnace, or in any convenient position above the grate bars. The
upper part of the tube A is surrounded by a concentric tube or hollow
cylinder B. C, C¹, are vanes or curved plates arranged in such manner
as to guide a current of air escaping round the top of the tube A into
the tube B; D, D, are radial partitions. The vanes C, C', and the
partitions D thus form air ducts or air passages. They may be varied in
shape and arranged to accommodate themselves to the construction and
disposition of the place to which the apparatus is applied. The atmos-

page_text: pheric or acriform currents are thus collected and drawn into the ducts
or tubes, so as to produce a circular jet or current of air, and a partial
vacuum at the upper part of the tube A.
In Figure 1 an ordinary cowl is used, but I prefer to use an improved
semi-spherical or dome-shaped cowl E, as shown in Figure 3. This
cowl is suspended or pivoted above the tube B, and prevents counter
currents or down drafts. By placing the apparatus C, C, D, upon the
tube B, Figures 1, 2, 3, the arrangement will be adapted for blowing in
or supplying air instead of withdrawing or exhausting air. The appa-
ratus arranged as shewn in the Drawing being disposed for the latter
purpose (exhausting air).
Having now described the nature of the said Invention, and in what
manner the same may be performed, I declare that I claim,-
First. The arrangement and combination of concentrically placed
tubes, cylinders, or hollow columns with vanes, plates, or deflectors and
partitions, substantially as described and for the purposes set forth.
Seccnd. The employment of a cowl or cap of a dome shape or of the
shape of a segment of a sphere, constructed and applied as described for
the purposes set forth.
Third. The general arrangement and combination of parts constituting
the improved apparatus above described for the purposes set forth.
In witness whereof, I, the said Eugene Theodore Noualhier, have
hereunto set my hand and seal, this Twenty-fourth day of June, in
the year of our Lord One thousand eight hundred and sixty-
nine.
