page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for
the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF FAN BLOWERS
FOR VENTILATING AND OTHER PURPOSES."-A communication from abroad.
by Milton Nobles, of St. Anthony, in the State of Minnesota, United
States of America.
Sealed the 5th February 1864, and dated the 20th November 1863.
PROVISIONAL SPECIFICATION left by the said William Edward Newton.
at the Office of the Commissioners of Patents, with his Petition, on
the 20th November 1863.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION
FAN BLOWERS FOR VENTILATING AND OTHER PURPOSES," to be as follows:-
This Invention of "Improvements in the Construction of Fan Blowers for
Ventilating and other Purposes," consists in gathering and expelling from an
apartment of any kind, the foul air or gases, and at the same time and by
the same apparatus drawing in fresh air from without, and forcing it into the
apartment to supply the place of that expelled, thus doing two things at one

page_text: and the same time, or by one and the same operation, both of which are
essential to a speedy change of air in the apartment to be ventilated as will
be explained.
The fan case is divided into two compartments and the two exterior
sides thereof are provided with openings or eyes, which communicate with
pipes or air ducts, which lead to the points or places where the four air is to
be taken in, and carried to, and where the fresh or pure air is to come from
respectively. At the top of the fan case there are two exit ducts, or air
trunks, through one of which the impure air is carried out of the apartment,
and through the other one of which the pure air is forced into the apartment
from without the building, structure, or place to be ventilated. The interior of
the fan case is divided by a partition corresponding to the division board of
the air trunks. A fan shaft extends through the fan case from side to side,
and may have on its projecting ends pullies, by which it may be driven.
Upon this shaft are arranged radial armis carrying wings or blades of any
suitable number or shape, for creating both a suction and exhaust current
through the apparatus from the apartment to the external air, and from the
exterual air to the apartment, or counter currents of foul and of pure air.
The fan case may be divided horizontally if desired and be hinged with a
suitable tightening and holding catch or latch for the purposes of access.
The operation of the apparatus is as follows:-The pipe or air duct of one
compartment having by hose or connecting pipes of any kind been introduced
into the place or apartment to be ventilated, and the other duct extended to
the external air where the foul air is to be discharged, and the air duct of the
other compartment being similarly extended to where the fresh or pure air is
to come from, whilst the other duct terminates in the place or apartment to be
ventilated or refurnished with pure air the fan is set in motion, which draws
in the foul air to the one compartment and expels it through the exit pipe,
and at the same time a volume of pure air is drawn into the other compart-
ment, and driven into the room or apartment through the supply pipe; thus in
a few moments removing the foul air and replacing it by fresh and pure air
by artificial and forced currents, and this process may be continuous or at
intervals as circumstances may require. The fresh air drawn in and distributed
through the apartinent may be cooled or moistened, or both, artificially, by
drawing or expelling it through an ice box, water chamber, or otherwise. For
expelling smoke or gases from gun decks or towers, or for ventilating the holds
of vessels this apparatus is peculiarly applicable, but may be applied to buildings
vaults, mines, and other places. The fan is both a suction and forcing fan
taking from a specific place, and forcing to another specific place the air

page_text: within its influence, and it may be run in either direction without changing
this characteristic of its operation, but in changing its motion the terminations
of its inlets and exits should be arranged accordingly.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office on
the 20th May 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Pateut, bearing date the Twentieth day of November, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Edward Newton, Her special license that I, the said
William Edward Newton, my executors, administrators, and assigns, or such
others as I, the said William Edward Newton, 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 Inven-
tion for "IMPROVEMENTS IN THE CONSTRUCTION OF FAN BLOWERS POR VENTI-
LATING AND OTHER PURPOSES," being a communication from abroad, upon the
condition (amongst others) that I, the said William Edward Newton, 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 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 William Edward Newton, 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, reference being had to the Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say):
1
Fans have been heretofore used in a tight case with air trunks leading to
and from them to supply fresh air to an apartment, or to expel foul air, one or
the other of these operations, but not both. An exhaust fan has also been used.

page_text: for drawing foul air from an apartment leaving the pure air to find its way into
such apartment without any artificial assistance. These separate operations
I do not claim as new as they only accomplish one half of what is necessary
for thorough ventilation.
The present Invention consists in gathering and expelling from an apart-
ment of any kind the foul air or gases, and at the same time and by the
same apparatus drawing in fresh air from without and forcing it into the
apartment to supply the place of that expelled, thus doing two things at
one and the same time, or by one and the same operation, both of which
are essential to a speedy change of air in the apartment to be ventilated, as
will be explained.
In the accompanying Drawings, Fig. 1 represents a view of one side of a
fan case and its air ducts; Fig. 2 is a similar view of the opposite side with
its. air ducts; Fig. 3 represents a vertical transverse section through the fan
case and fan, and the upper pair of air ducts.
A, A¹,, represent the two exterior sides of a fan case the eyes of which are
tightly closed up as at B, B, and from which closed up eyes, pipes, or air
ducts C, C, lead to the points or places where the foul air is to be taken in
and carried to, and where the fresh or pure air is to come from respectively.
At the top of the fan case there are two exit ducts or air trunks D, D¹,
through one of which the impure air is carried out of the apartment, and
through the other one of which the pure air is forced into the apartment from
without the building, structure, or place to be ventilated. The interior of the fan
case is divided by a partition E corresponding to the division board F of the air
trunks D, D¹. A fan shaft G extends through the fan case from side to side,
and may have on its projecting ends pullies H, H', by which it may be driven.
Upon this shaft are arranged radial arms I, 1', carrying wings or blades J, J¹,
of any suitable number or shape for creating both a suction and exhaust
current through the apparatus from the apartment to the external air, and
from the external air to the apartment, or counter currents of foul and of pure
air. The fan case may be divided horizontally if desired as at a, and be.
hinged as at 6 with a suitable tightening and holding catch or latch at c, for
the purposes of access to the interior.
The operation of the apparatus is as follows:-The pipe or air duct C is by
hose or connecting pipes of any kind made to communicate with the place or
apartment to be ventilated, and the other duct D is extended to the external
air where the foul air is to be discharged. The air duct C¹ of the other
compartment is similarly extended to where the fresh or pure air is to come
from, and the other duct D', terminates in the place or apartment to be

page_text: ventilated or refurnished with pure air. The fan is then set in motion, and
draws in the foul air through the pipe C, and expels it through the exit pipe
D, and at the same time a volume of pure air is drawn in through the duct
C', and is driven into the room or apartment through the fresh air supply
pipe D. Thus in a few moments the foul air will be removed and replaced
by fresh and pure air, by artificial and forced currents, and this process may
be made either continuous or at intervals as circumstances may require. The
fresh air drawn in and distributed through the apartment may be cooled or
moistened, or both, artificially, by drawing or expelling it through an ice box,
water chamber, or otherwise. For expelling smoke or gases from gun decks
or towers, or for ventilating the holds of vessels, this apparatus is peculiarly
applicable, and it may be also applied to buildings, vaults, mines, and other
places. The fan is both a suction and forcing fan taking from a specific
place, and forcing to another specific place the air within its influence, and it
may be made to rotate in either direction without changing this characteristic
of its operation, but in changing its motion the terminations of its inlets and
exits should be arranged accordingly.
Having thus fully described the object and purpose of my Invention, what I
claim therein as new and desire to secure by Letters Patent, is, in combination
with a fan case having closed eyes, and a divided fan, the double set of inlet
and exit air ducts or passages C, C¹, and D, D¹, constructed, arranged, and
operating together for the purpose of drawing in, and forcing through it
counter currents of pure and impure air substantially as and for the purpose
described.
In witness whereof, I, the said William Edward Newton, have here-
unto set my hand and seal, the Twentieth day of May, in the year of
our Lord One thousand eight hundred and sixty-four.
