IMPROVED APPARATUS FOR SIMULTANEOUSLY FORCING AND EXHAUSTING AIR, OR VAPOUR
Year: 1884

page_text: I JOHN ADAMS of 99 Cardwell Street, Liverpool in the County of Lancaster,
Plumber do hereby declare the nature of my said Invention for IMPROVED
APPARATUS FOR SIMULTANEOUSLY FORCING AND EXHAUSTING AIR, OR VAPOUR to
be as follows:-
My Invention has for its object the construction of an apparatus in which are
positioned two fans, the function of one being to deliver fresh, or hot, or cold air,
or hot and cold air, and the function of the other being to discharge or exhaust foul
air, or vapour, as hereinafter described, the fans being arranged that they are
worked by the action of each other, or by a suitable motor.
The apparatus consists of a chamber of cast iron, or other suitable material,
provided with a diaphragm which divides the chamber into two compartments, one
of which is provided with an inlet for heated air and the other is provided with an
inlet for fresh, or cold air, (both inlets being provided with regulating valves), and
an outlet for the discharge of the hot, or cold air separately, or together The
diaphragm is provided with a central opening which effects communication between
the two compartments. Within the chamber there is provided a fan the function
of which is to draw in the heated air and the fresh, or cold air, or the heated, or the
cold air separately and discharge such air either mixed, or separately through the
discharge outlet of the chamber, for distinction, I will term this fan the "supply
fan." On the same spindle as the supply fan and above it I provide a second fan,
which I will term the discharge fan. This fan is situated in a chamber either
immediately, or some distance above the supply fan. The function of the discharge
fan is to exhaust, or draw off air, or vapour from the space being supplied by the
supply fan. The chamber in which the discharge fan is situated is provided with
an inlet and a discharge, or outlet, and when the apparatus is applied for purposes
such as ventilating rooms, buildings, ships cabins and holds, the chamber of the
discharge fan may be connected to a chimney, or equivalent shaft so that the draft
of air through the chamber will work the discharge fan and so through its being
on the same spindle, will operate the supply fan, thus constituting an automatic

page_text: supply and discharge ventilating arrangement. When the apparatus is used for
purposes such as drying wet, or damaged cotton, heated air is supplied from a
suitable heating apparatus to the supply fan, which in this case is driven by a belt,
or gearing from a suitable motor and the cotton being distributed in the drying
room on suitable shelves, or trays the hot and fresh air is caused to pass over the
cotton and the vapour given off from the cotton is drawn away by the discharge
fan which receives motion together with the supply fan. In the application of the
apparatus to the cooling of Brewers worts and like cooling apparatus cold air only
is supplied by the supply fan, the discharge fan being used to exhaust the vapour.
Dated this twenty fifth day of March 1884.

page_text: I JOHN ADAMS of 99 Cardwell Street, Liverpool in the County of Lancaster,
Plumber do hereby declare the nature of the said Invention for IMPROVED
APPARATUS FOR SIMULTANEOUSLY FORCING AND EXHAUSTING AIR, OR VAPOUR
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My Invention has for its object the construction of an apparatus in which are
positioned two fans, the function of one being to deliver fresh, or hot, or cold air,
or hot and cold air and the function of the other being to discharge, or exhaust foul
air or vapour, as hereinafter described, the fans being arranged that they are
worked by the action of each other, or by a suitable motor.
The following is a description of my Invention in such full, clear and exact terms
as to enable anyone skilled in the art to which it belongs to put into practice and
use the same, reference being had to the accompanying sheets of Drawings making
a part of this Specification and to the letters and figures of reference marked
thereon, like letters and figures being used to denote the same, or corresponding
parts throughout the various views and figures.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a sectional elevation of an apparatus constructed according to my
Invention.
Figure 2 is an outside view of Figure 1.
Figure 3 is an end view of Figure 1.
Figure 4 is a section through Z Z Figure 2.
Figure 5 is a section through Y Y Figure 2.
Figure 6 is a section through X X Figure 2.
Figure 7 is a sectional elevation of a room showing my Invention applied
thereto.
The apparatus according to my invention consists of a chamber A of iron, or
other suitable material provided with a diaphragm a which divides the chamber
into two compartments B C one of which is provided with an inlet D for hot air
and the other compartment C is provided with an inlet E for fresh, or cold air, both
the inlets D and E being provided with suitable regulating valves. The chamber A
is provided with an outlet F for the discharge of the hot, or cold air together, or
separately. The diaphragm a is provided with a central opening a¹ which effects a
communication between the compartments B and C.-Within the compartment B
there is provided a fan H, the function of which is to draw in the heated air and
the fresh, or cold air, or the heated, or the cold air separately and discharge such air,
either mixed, or separately through the discharge outlet F of the chamber A. For
distinction will term the fan H the supply fan and it is provided with straight
radial blades. The supply fan H is mounted on and carried by the spindle h and
on the same spindle h as the supply fan H and above it, I provide a second fan J,

page_text: which I will term the discharge fan and it is provided with inclined radial blades
and is situated in a chamber K either immediately above, as shown in the
Drawings, or some distance above the chamber A and the supply fan H. The
function of the discharge fan J is to exhaust, or draw off air, or vapour from
the room, or space being supplied with air by the fan H. The chamber K is
provided with an inlet L and with an outlet M. When the apparatus is applied to
purposes such as ventilating rooms, buildings, ships cabins and holds, the discharge
outlet M may be connected to a chimney Ñ as shown at Figure 7, or to a shaft N
as shown in dotted lines, so that the draught of air through the chamber K will
work the fan J and thereby through the fan J being on the same spindle h the
supply fan H will be operated, thus consistituting an automatic supply and discharge
ventilating arrangement.
When the apparatus is used for purposes such as drying wet, or damaged cotton,
heated air is supplied from a suitable beating apparatus to the supply fan H which
in this case is driven by an endless rope, or band on the pulley from a suitable
motor. The material to be dried, being distributed in a drying room on shelves, or
trays the hot and fresh air is caused to pass over the material to be dried, and the
vapour given off is drawn away by the discharge fan J which receives motion
together with the supply fan H.
In the application of the apparatus to the cooling of brewers worts and for like
refrigerating purposes cold air only is supplied by the fan H and the fan J is used
to exhaust the vapour.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
First The combination of the fan (H) and the fan (J) mounted one above the
other, as herein set forth and operating as described for the purposes specified and
as illustrated in the Drawings.
Second The arrangement and construction of fan blades as herein set forth for
the purposes specified and operating as described and as illustrated in the Drawings.
Dated this twenty third day of December 1884.
