It consists of four or more horizontal triangular plates of any material fixed to a
frame of any material sloping inwards and downwards and converging to a centre
at any angle up to 90° and of four or more other horizontal triangular plates of any
material sloping inwards and upwards to the same centre at any angle up to 90°
and of four or more other triangular vertical plates set at right angles to the eight
or more horizontal plates previously described the said vertical plates dividing the
head into four or more compartments all converging to one centro as shewn in the
diagram marked N° 1 and of a tube either round or square divided into two or
more compartments descending vertically from the said centro. Each compartment
communicating with one or other of the pairs of sloping plates to which they are
fixed. These vertical tubes may be continued as such to any convenient distance
and then turn horizontally right and left into a horizontal tube which may be
made of any material and of any diameter the relative positions of the vertical
tube descending from the sloping plates and of the horizontal tubes in which they
extend is shewn in figure 2. The last named horizontal tube runs into at each of
its ends another tube set at right angles to itself. These last tubes are open at
each end and are intended to run athwart the roof and open out each side of it.
A plan of these three horizontal tubes with the vertical tube descending into it
and branching right and left in the middle one of the three is shewn in figure 3.
From the centre of the middle tube descends another vertical shaft of larger or less
diameter as required and is divided by a plate running down its centre falling in
the same plane as the two side shafts and terminating in an expanded cone having
its mouth open. This cone may be of any size required. The position of this cone
is shown by figure . It is immaterial whether more than one cone be fixed on to
the apparatus The principle on which this Ventilator acts is partly by injection
from above and partly by suction from the transverse tubes

RICHARD OAKLEY of N° 235 High Holborn in the County of Middlesex
Ventilating Engineer "IMPROVED APPLIANCES FOR VENTILATING CHURCHES,
SCHOOLS AND OTHER BUILDINGS
"
This invention has for its object improved appliances for ventilating churches
schools and other buildings.
The improved ventilating appliances constituting my invention are represented
by the drawings annexed. I call the apparatus "The Eolus Invisible Exhaust
Roof Ventilator
"
It consists of four or more horizontal triangular plates of any material fixed to
a frame of any material sloping inwards and downwards and converging to a
centre at any angle up to 90° and of four or more other horizontal triangular
plates of any material sloping inwards and upwards to the same centre at any
angle up to 90° and of four or more other triangular vertical plates set at right
angles to the eight or more horizontal plates previously described the said vertical
plates dividing the head into four or more compartments all converging to one
centre as shown in the diagram marked N° 1 and of a tube either round or square
divided into two or more compartments descending vertically from the said centre.
Each compartment communicating with one or other of the pairs of sloping plates
to which they are fixed.
Figure 1 is an horizontal section taken on the line 1. 1. in Figure 1. Figure 1b
is a vertical section.
In these figures the triangular plates referred to above and sloping inwards and
upwards are marked a. a. a. a and b. b. b. b. are the vertical plates. c' and c² are
the two compartments of the central tube or tubes.
These vertical tubes may be continued as such to any convenient distance and
then turn horizontally right and left into a horizontal tube which may be made of
any material and of any diameter. The relative positions of the vertical tube
descending from the sloping plates and of the horizontal tubes in which they
extend is shewn in Figure 2. The last named horizontal tube runs into at each of
its ends another tube set at right angles to itself. These last tubes are open at
each end and are intended to run athwart the roof and open out through each side
of it. A plan of these three horizontal tubes with the vertical tube descending
into it and branching right and left in the middle one of the three is shown in
Figure 3.
In Figure 3 the two compartments of the descending vertical tube are again
marked c. c-they branch horizontally into the horizontal tube d and this
communicates with the two tubes e. e. which pass through the upper part of the
roof from side to side. In Figure 2 the arrangement of the parts in relation to
the roof is seen at the upper part immediately beneath the ridge is the apparatus
consisting of the plates a. a. with corresponding upper plates and the vertical
plates b together forming funnel like entrances to the divided pipe c¹. c².—The
larger piped into which c. c. open is seen below as are also portions of the pipes e. e.
From the centre of the middle tube descends another vertical shaft of larger or
less diameter as required and is divided by a plate running down its centre falling
in the same plane as the two side shafts and terminating in an expanded cone
having its mouth open. This cone may be of any size required. The position of
the cone is shewn by Figure 2. It is immaterial whether more than one cone be
fixed on to the apparatus. Sometimes I divide the head shown by Figure 1 into

page_text: two parts and separate the parts by an interval in order to obtain better exposure
on the two sides of the roof. The principle on which this ventilator acts is partly
by injection from above and partly by suction from the transverse tubes.
What I claim is the improved ventilating appliance herein described which I
call the Eolus Invisible Exhaust Roof Ventilator.
In witness whereof I the said Richard Oakley have hereunto set my hand
and seal this twelfth day of October in the year of our Lord One thousand eight
hundred and eighty three.
