IMPROVEMENTS APPLICABLE TO THE VENTILATION OF WATERCLOSETS
Year: 1877

page_text: LETTERS PATENT to Thomas Waller, of Fish Street Hill, in the City of London,
for the Invention of "IMPROVEMENTS APPLICABLE TO THE VENTILATION OF
WATERCLOSETS."
PROVISIONAL SPECIFICATION left by the said Thomas Waller at the Office
of the Commissioners of Patents on the 19th June 1877.
THOMAS WALLER, of Fish Street Hill, in the City of London.
APPLICABLE TO THE VENTILATION OF WATERCLOSETS.""
"
IMPROVEMENTS
This Invention consists of improvements applicable to waterclosets in order to
provide for efficient ventilation of same.
--
In carrying out my Invention, I adopt nainly the following arrangements :-
The pan has air openings at the side thereof in communication with the inside of
the pan, and at the back of the pan is another opening to which a tube or duct is
connected, same passing into the ventilating shaft fixed immediately over the seat
of the watercloset, same being either let into the wall or fitted against the wall.
I admit air to the front or sides under the scat of the closet, and so that the air
passes around the pan and up and out above the pan, or through suitable- openings
fixed for that purpose.
The air then passes up to and into the said ventilating shaft,
this being accomplished by fixing over the seat of the closet an inclined flap or
cover, leaving space between the front and back of the sent.
When there is more than one closet to a house, I prefer to arrange the ventilating
shafts so that they rise together, and to the top of the said shafts, and arranged
so as to act upon the whole of the shafts, I apply an air extractor or exhauster.
When these arrangements are used, the action is as follows:-Air, when a person
is seated on the closet, passes through the openings. at. the side into the closet pan,
and the same passes up the tube or duct. When the lid is closed, the air that issues
from the front or sides passes up from around the pan or through suitable openings
made for that purpose into the space between the lid and the seat, and thence out
through the air shaft, the exhauster at the top thereof assisting to draw up the said
air, and with it the vitiated air from the closet pan.

page_text: For ventilating ordinary closets, I dispense with the particular form of pan
herein-before described, and arrange the other parts of my Invention so as to effect
the ventilation of ordinary closets without otherwise disturbing their general
arrangements; but to ordinary pans already fixed, I sometimes fix a ring, the shape
of the pan, between the pan and the seat of the closet, so as to allow the ventilation 5
of the pan, as before described.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Thomas Waller in the Great Seal Patent Office on the 19th December
1877.

IMPROVEMENTS
This Invention consists of improvements applicable. to waterclosets in order to
provide for efficient ventilation of same.
In carrying out my Invention, I adopt the following arrangements:-The pan
has air openings at the side thereof in communication with the inside of the pan,
passing away the air into the ventilating shaft fixed immediately over the seat of
the watercloset, same being either let into the wall or fitted against the wall. I
admit air to the front or sides under the seat of the closet, and so that the air passes
around the pan and up and out above the pan, or through suitable openings fixed for
that purpose. The air then passes up to and into the said ventilating shaft, this
being accomplished by fixing over the seat of the closet an inclined flap or cover,
leaving space between the front and back of the seat.
When there is more than one closet to a house, I prefer to arrange the ventilating
shafts so that they rise together, and to the top of the said shafts, and arranged so
as to act upon the whole of the shafts, I apply an air extractor or exhauster.
A
The action of these arrangements is as follows:- When a person is seated on the
closet, air passes through the openings at the side into the closet pan, and the same
passes up the ventilating shaft. When the lid is closed, the air, that issues from the
front or sides passes up from around the pan or through suitable openings. made for
that purpose, into the space between the lid and seat, and thence -out through
the air shaft, the exhauster at the top thereof assisting to draw up the said air, and
with it the vitiated air from the closet pan.

For ventilating ordinary closets, I dispense with the particular form of pan
herein-before described, and arrange the other parts of my Invention so as to effect
the ventilation of ordinary closets without otherwise disturbing their general
arrangements; but to ordinary pans already fixed, I sometimes fix a ring, the 'shape
of the pan, between the pan and the seat of the closet, so as to allow of the venti-
lation of the pan, as before described.
Having thus far described the nature of the said Invention, and incidentally
intimated in what manner the same is to be performed or put in practice, I will
now proceed (aided by the accompanying Drawings) to further and particularly
describe and ascertain in what manner the same is to be performed or carried out
in practice, that is to say :-

page_text: dispensed with, as shewn in Figs. 2 and 5.
B, ventilating shaft, proceeding from under side of seat, as shewn.
D, front of watercloset with opening or openings at d.
E, seat of closet.
F, lid of closet, which is fixed as shewn.
G, opening in communication with the ventilating shaft.
H, damper, which, when the lid or flap is up, closes over opening or grating G.
The pan shown in Figs. 2 and 5 is of the ordinary construction, the opening into
the ventilating shaft being between the seat and the under side of lid, as shown.
The damper may, it is evident, be applied in various ways, so that when the lid
is closed, the same comes in back or front of grating.
The damper may, in some cases, be dispensed with.
Having now particularly described and ascertained the nature and object of the
said Invention, and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the Invention of "Improvements Applicable
to the Ventilation of Waterclosets," substantially as the same is combined and
arranged as herein-before set forth and described, and illustrated by the accom-
panying Drawings.
In witness whereof, I, the said Thomas Waller, have hereunto set my hand
and seal, this Fifteenth day of December, in the year of our Lord One thou-
sand eight hundred and seventy-seven.
