Complete Specification Left, 30th Apr., 1891-Accepted, 13th June, 1891
Figure is the side elevation.
The apparatus is constructed as follows:
No. 1. A represents an air cylinder or oblong box with double revolving fans
vandyked in centre showing glass rosettes in the front portion for illumination
purposes and suction combined so constructed as to have rectangular open ends,
ends covered with louvres or perforated material and have between them an internal
opening or space and take the form of a suitable convergent angle or throat for
allowing the fumes or obnoxious smells to pass away into the atmosphere, never
to return.
B represents two air funnels with bell mouth ends extended from the interior of
the buildings with valve to open and shut for regulating the suction and is
connected with the back of each end of air cylinder marked A. for conveying
vapours from the interior of buildings and are so arranged to be adjustable to meet
the required thickness of any wall.
C represents semicircular circulating suction drum apperture inserted between
funnels marked B B and is so constructed with outside louvres and is connected in
the middle portion of air cylinder from front to exterior with rectangular appertures
or convergent angle or throat which baffle the atmospheric pressure from the outside
of walls or carriages for allowing the fumes to pass away.
D represents four rectangular divisions or convergent angles or throats with
outlet venetians situated on each side of semicircular circulating suction apperture
drum for assisting the suction from air funnels marked B B.
E represents two rectangular tubes with venetians for the admission of wind and
fresh air to assist the suction from funnels marked B B causing all vapours to be
readily conveyed into semicircular circulating suction drum.
Frepresents two coloured glass rosettes for illuminating purposes inserted in
front portion of air cylinder.
G. represents two gas or oil jets to assist the suction air cylinder and conveys
more rapidly by the assisting power of heat a continuous stream of obnoxious air
from the interior of a building or railway carriage compartment.

page_text: Hrepresents a double conical outlet in centre of cylinder or oblong box
marked A.
1. represents a double revolving fan vandyked driven by atmospheric pressure
and is so arranged to catch the wind from the outer portion of double cone
marked H.
J. represents screw shaped revolving fan connected to the revolving fan marked 1
and is inserted in the interior of double conical outlet marked I both fans working
simultaneous for assisting the suction in semicircular circulating appertime drum.
Krepresents fan shaft with centre and centrical sockets by preference I use ball
bearings and centrical sockets.
Lrepresents two tubes with centrical sockets for fan shaft with check nuts at top
and bottom taking the form of a lubricator for centrical sockets.
M represents regulating valve in bell mouth ends of funnels marked B B.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
1st. The powers of suction and its outlets caused by semicircular circulating
drum.
2nd. The prevention of admission of wind to the interior of buildings or railway
carriages.

COMPLETE SPECIFICATION.
Improvements in Wall Ventilators.
WILLIAM MORRISON of 2 John Street Terrace, New Swindon, Smith do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvement in outlet wall ventilators. The object
being by improved arrangement and construction of parts to provide a ventilating
apparatus to draw obnoxious vapours from the interior of buildings and prevent
back draughts. The outlet wall ventilator consists of an oblong cylinder for
receiving obnoxions vapours and so arranged with a semicircular circulating suction
aperture drum for the exit of obnoxious vapours. I employ gas or oil jets to assist
the power of auction which will be of more handly economical construction than
ordinary; the two illuminating glasses inserted in face plate of ventilator for evening
purposes & by means of a double vandyked fan situated in the middle of ventilator,
all vapours are quickly drawn through semicircular circulating suction drum, never
to return again.
The same constituting as a whole an improved appliance for wall ventilators,
This invention will be applicable for railway carriages.
In the sheet of drawings "left with the Provisional Specification" I have
represented the whole.
Fig. 1. is a sectional plan.
Fig. 2 is the front elevation fixed on outside of wall.
Fig. 3 is the side elevation.
The apparatus is constructed as follows:
A. represents an air vessel or oblong box with four divisions inside, they are fixed
to back and front marked D D D D. On the front alevation is a fan 1, louvres
and glasses marked F F.
B 13. represents two adjustable air funnels fixed to the oblong box marked A
with bell mouth ends, they extend from interior of the building for conveying
vapours from the interior of the building into the oblong box A. and then drawn
into the circulating suction drum ('.

page_text: C represents semicircular circulating suction drum fixed to back of A between
air funnels B B for receiving the vapours drawn through B B into box A and then
conveyed into circulating suction drum and then passed out through fan I and
louvres in front over & under fan.
DDD D. represents four divisions fixed inside of box A with outlet venetians on
same for allowing vapours to pass through louvres at side of glass F. F.
E E. two rectangular tubes fixed at bottom of divisions D D for assisting the
suction in C.
F. F. two coloured glasses for denoting when gas jets marked G G are lit.
G. G. represents two gas or oil jets fixed on tubes E E to assist the suction from
air funnels B B, when burning.
H. conical outlet in centre of oblong box A between fan I and drum C with fan J
revolving in centre of same.
I. outside revolving fan for suction, supported on brackets with spindles and two
centrical sockets in front of box A. for driving J.
J. is a screw shaped revolving fan connected to fan I and is in centre of conical
outlet F to assist the centre suction in C.
K. is the fan shaft for carrying fans I. .J.
L. is a tube for lubricating the centres & sockets for fan shaft K.
M. M. represents regulating valves in ends of adjustable air funnels B B to open
and shut for checking the suction from interior of building.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what same
is to be performed, I declare that what I claim is
1st. The powers of suction and its outlets caused by semicircular circulating
suction drum.
2nd. The prevention of admission of wind to the interior of building or railway
carriage.
