PROVISIONAL SPECIFICATION left by the said Thomas Rowan at the Office
of the Commissioners of Patents on the 14th April 1882.
THOMAS ROWAN of Coleshill Street in the county of Middlesex and of Mosley
Street, Manchester in the county of Lancaster Engineer "IMPROVEMENTS IN
VENTILATING AND APPARATUS THEREFOR
"
This invention relates to further improvements on former inventions for which
I obtained Letters Patent No. 5303 dated the seventeenth day of December, one
thousand eight hundred and eighty, No. 162 dated the thirteenth day of January
one thousand eight hundred and eighty one, No. 505 dated the fifth day of February
one thousand eight hundred and eighty one respectively, and on an invention for
which Provisional Protection was granted to me No. 5351 dated the seventh day
of December one thousand eight hundred and eighty one, the present improve-
ments having for object chiefly to dispense with the use of a cowl or the like for
producing an induced current, and further in the case of sewers, drains, water
closets and the like, to destroy and render innocuous bacteria and other disease
germs or virus.
A suitable arrangement for carrying out my invention is as follows:-
I provide a suitable stove or oven heated by gas or otherwise; through the
stove or oven passes a series of tubes; the lower ends of the said tubes are in
communication with the sewer, drain, water closet or the like, the other ends
communicating with an up shaft or chimney into which also pass the products of
combustion from the stove or oven.
For ventilating buildings, rooms or other places, the arrangement is substantially
the same as that hereinbefore described except that the building, room or other
place is in communication with the stove or oven instead of the stove or oven being
in communication with the sewer or the like.
When required each branch drain is provided with an air inlet box or shaft
having a valve opening inwards, and regulated to any required pressure, the object
of this inlet being to allow a down current of air, at the same time preventing
any escape of sewer or drain air or gas, such down current of air serving to insure
a constant current of external air towards the shaft which cuts off the main sewer
from the building and likewise insures a current of air passing freely up the soil
pipes

"IMPROVEMENTS IN
VENTILATING AND APPARATUS THEREFOR"
This invention relates to further improvements on former inventions for which
'I obtained Letters Patent No. 5303, dated the seventeenth day of December, onc
thousand eight hundred and eighty; No. 162, dated the thirteenth day of January,
one thousand eight hundred and eighty one; No. 505, dated the fifth day of
February one thousand eight hundred and eighty one; No. 5351, dated the seventh
-day of December, one thousand-eight-hundred and eighty one, and No. 276, dated
the nineteenth day of January one-thousand eight hundred-and-eighty-two-
respectively, the present improvements having for object chiefly to dispenso with
the use of a cowl or the like for producing an induced current, and further in the
case of sewers, drains, water closets, and the like, to destroy and render innocuous
bacteria or disease gerins and virus.
1 construct a suitable arrangement for carrying-out-my invention in the following
manner: —
I employ a stove or oven heated by gas or otherwise through which passes a
series of tubes;-the-tower-ends-of_the_said tubes are in communication with the
sewer, drain, water closet or the like, the other ends communicating-with-an_up_
shaft or chimney into which also pass the products of combustion from the stove
or oven.
For ventilating buildings, rooms or other places, the arrangement is substantially
the same as that hereinbefore described except that the building, room, or other
place is in communication with the stove or oven instead of the stove or oven being
in communication with the sewer or the like.
When required cach branch drain is provided with an air inlet box or shaft
having a valve opening inwards and regulated to any required pressure, the object
of this inlet being to allow a down current of air at the same time preventing any
escape of sewer or drain air or gas such down current of air serving to ensure a
constant current of external air towards the shaft which cuts off the main sewer
from the building and likewise ensures a current of air passing freely up the soil
pipes.
In order to enable my invention to be better understood I will proceed to
describe the same by reference to the accompanying drawing in which figure 1, is
an elevation partly in section of part of a building with my improvements for
ventilating the saine applied thereto; figure 2, is a detached sectional view on a
larger scale of the stove or heating apparatus; figure 3, is a similar view of the
stove or heating apparatus except that it is in communication with the ordinary
Blue of a building instead of with a separate fluc. Figure 4, is a section shewing a
modified arrangement of the tubes of the stove and figure 5, a section shewing
the ventilating arrangement applied to a sewer.
In figure 1, a, is the stove, oven or heating apparatus; the said apparatus as
shewn in figures 2, and 3, consists of a stove constructed substantially in the
manner described in the specification of my said former Letters Patent No. 5351,
dated the seventh day of December, one thousand eight hundred and eighty one.
The lower ends of the tubes b, being in communication by means of the pipe c,
with the drain d, (or with the sewer, water closet or the like according to circum-
stances) the other ends c, of the tubes communicate with the up shaft or chimney,

page_text: outside the building or as shewn in figure 3, with, the ordinary flue g, of the
building; g, air injecting pipe of the upshaftf; h, air inlet box or shaft communi-
cating with the drain d; i, i, the valves of the air inlet box the said valves
opening inwards and being regulated to any required pressure; i, dividing plato;
the air injecting pipe g¹, is provided at the top g³, with valves opening inwards
similar to those shewn at i, i;j, is the ordinary soil pipe of the water closets w, w, w,
the said soil pipe is elbowed at h, and provided with air injecting cones_l, in a
manner similar to that described in the specification of my said former Letters
Patent No. 162, dated the thirteenth day of January one thousand eight hundred
and eighty one.
When applying my improvements I prefer that the waste water from all baths
and the like should be discharged outside the building as at m, into the open
head n, of a pipe o, which itself discharges into an open grating p, communicating
as shewn with the drain d.
From the preceding description it will be understood that if the stove a, be
heated by gas or otherwise an induced current will be produced in the upshaft f
and fresh air will be drawn into the pipe c, through the injecting pipe g¹, the foul
air and gases from the drain d, (or from the sewer as the case may be) will be
drawn through the stove a, and will pass with the products of combustion into the
atmosphere through the upshaft f, and the heat to which the suid air and gases
are subjected in passing through the stove may be sufficient to destroy and render
innocuous bacteria or disease germs and virus which the said air and gases inay
contain, before passing into the atmosphere.
Air will also pass into the drain & through the valves i, in the inlet box h, so that
there will be practically a constant current of external air towards the shaft c, ƒ,
which cuts off the main sewer from the building and likewise ensures a current of
air passing freely up the soil pipej; the valves in the inlet box and in the top of
the air injecting pipe g¹ preventing any escape from the drain d.
For ventilating rooms, buildings or other places the stove a, should be placed
within the building but instead of the lower ends b, of the tubes being in.communi-
cation with the sewer or drain the said ends would be open to the room or building
and would be covered by an ornamental grating; the upper ends of the tubes
would be in communication either with the ordinary house flue or with a separate
flue according to circumstances.
Instead of the tubes of the stove or heating apparatus being arranged as shewn
in figures 2 and 3, they may consist of a number of serpentine tubes as shown in
figure 4, placed side by side.
Figure 5, shews the improvements applied to a sewer; A is an ordinary sower;
Ba receiver similar to that described in the specification of my said former Letters
Patent No. 276 dated the nineteenth day of January one thousand eight hundred
and eighty two; c, is the vertical pipe leading from the receiver B, into thic
heating apparatus a, whence it passes into the upshaft f. The action is substantially
the saine as that hereinbefore described. This arrangement of heater is specially
applicable for introducing fresh warned air into railway carriages in the manner
described in the specification of my said former Letters Patent No. 5351, dated the
seventh day of December one thousand eight hundred and eighty one.
Having thus described any said invention and the best means with which I am
acquainted for carrying the same into effect I wish it to be understood that what
I claim is
Firstly. The use of apparatus such as is herein described for ventilating sewers,
drains, water closets or the like by the employment of a stove or heating apparatus,
such as is herein before referred to, in communication with the sewer, drain or
water closet pipe and with an upshaft or chimney substantially as hereinbefore
described and represented in the accompanying drawing.
Secondly. The use in the manner described for ventilating buildings, rooms
and the like of a stove or heating apparatus such as that described substantially

page_text: in the manner and for the purposes hereinbefore described and represented in the
accompanying drawing.
In Witness whereof I the said Thomas Rowan have hereto set my hand
and seal this tenth day of October in the year of our Lord one thousand
eight hundred and eighty two
