PROVISIONAL SPECIFICATION left by the said Thomas Rowan at the Office
of the Commissioners of Patents on the 19th January 1882.
"
THOMAS ROWAN of Coleshill Street, in the County of Middlesex, Engineer.
IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR VENTILATING WATER-
CLOSETS, URINALS, DRAINS, SEWERS, AND THE LIKE, APPLICABLE ALSO FOR OTHER
PURPOSES."
This invention has reference to further improvements on my 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 and No. 505 dated the
fifth day of February one thousand eight hundred and eighty one respectively, and
the present improvements consist chiefly in employing a jet or jets of water for
producing an induced current for carrying off the foul air and gases from water
closets, urinals, drains, sewers, and the like, the said water also serving for washing
or purifying the said foul air and gases before the same escape. The said improve-
ments are also applicable for treating smoke, chemical fumes and the like from
chimneys and flues and the products of combustion from gas or other stoves.
In carrying out my improvements I employ a jet or jets connected with a suitable
supply of water and so placed in a tube open to the receptacle or the like from
which the gases or other noxious products are to be drawn and treated, that an
induced current will be produced either direct or spirally in such a manner that
the said gases or other products will be abstracted and washed before being
discharged.

by the said Thomas Rowan in the Great Seal Patent Office on the 19th July
1882.
THOMAS ROWAN of Coleshill Street, in the County of Middlesex, Engineer.
"IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR VENTILATING WATER-
CLOSETS, URINALS, DRAINS, SEWERS AND THE LIKE, APPLICABLE ALSO FOR OTHER
PURPOSES."
This invention has reference to further improvements on my 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 and No. 505, dated
the fifth day of February, one thousand eight hundred and eighty one respectively,
and the present improvements consist chiefly in employing a jet or jets of water
for producing an induced current for carrying off the foul air and gases from
water closets, urinals, drains, sewers and the like, the said water also serving for
washing or purifying the said foul air and gases before the same escape. The said
improvements are also applicable for treating smoke, chemical fumes and the
like from chimneys and flues and the products of combustion from gas or other
stoves.
In carrying out my improvements I employ a jet or jets connected with a suitable
supply of water and so placed in a tube open to the receptacle or tho like from
which the gases or other noxious products are to be drawn and treated, that an
induced current will be produced either direct or spirally in such a manner that
the said gases or other products will be abstracted and washed before being
discharged.
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 a
sectional elevation shewing one arrangement for carrying out my invention as
applied to a water closet; figure 2, sectional elevation showing a similar arrange-
ment applied to a urinal'; figure 3, is a sectional elevation shewing the present
improvements adapted to a receiver employed in ventilating sewers drains cesspits
and the like; figures 4, and 5, sectional elevations shewing arrangements for treating
smoke, chemical fumes 'and 'the like from chimneys and flues; figure 6, is a sectional
elevation of a modification of 'the arrangement specially suitable for treating 'fumes
from chemical products; figure 7, views of nozzles suitable for producing spiral
jets. Figure 8, section shewing the improvements applied to a stove. Similar letters
in 'all the figures represent similar or corresponding parts.
In the arrangement shewn in figure 1, a, is the water closet pan communicating
by means of the connection 'b, with the vertical tube c, provided with a nozzle d,
in communication with a supply of water; the lower end of the tube c, opens into
a box or receiver e, having a trapped discharge pipe f; g, connection for the outlet
or discharge tube for the washed or purified air or gases.
By this construction if water under pressure be supplied to the nozzled, by any
suitable means it will be discharged in a series of jets or spray into the vertical
tube c, and will thereby produce an induced current which will draw or abstract
the foul and other air and gases from the pan a, and the spray or jets will carry
the said air and gases along into the box e, from which they will escape through g,

page_text: after having been washed by the water during their passage; the water from the
box e, is discharged through the outlet f, carrying with it any matters condensed
from the said air and gases.
In figure 2, the hereinbefore described arrangement is shewn applied to urinals,
a, a, being the basin; the operation being substantially the same as that described
by reference to figure 1, needs no further description.
In figure 3, which shews a method of ventilating a sewer or drain; A is an
ordinary sewer; B, a receiver similar to that described in the specification of my
said former Letters Patent No. 5305 of 1880; C, is a pipe leading from the top
of the receiver into the vertical tube c, provided with a nozzle d, as in figures 1,
and 2.
By this arrangement the air or gases will be drawn from the receiver by the
action of the jet of water into the tube c, and will be washed, before being discharged
through the outlet g.
In the arrangement shewn in figure 4, which is adapted for treating smoke,
chemical fumes and the like from chimnies and flues or for scrubbing or purifying
coal gas I employ a number of vertical tubes c, arranged side by side and commu-
nicating with one another and each being provided with a water nozzle; smoke,
chemical fumes or the like from the chimney or flue or coal gas from a retort will
by the action of the first nozzle be drawn from b, into the first vertical tube c, and
will be drawn into the tube No. 2 and thence into the tube No. 3, and so on, being
washed in its passage through each tube; f, f, f, outlets for the water.
The arrangements shewn in figure 5 is similar to that shewn in figure 4, with
the addition of trays h, which are provided to contain lime or other absorbing and
purifying agents.
In the modified arrangement specially adapted for treating fumes from chemical
products shewn in figure 6, the nozzle is placed horizontally and the operation is
substantially the same as that herein before described.
Figure 8, shews the section of a stove constructed similarly to that described in
the specification of my former Letters Patent No. 5351, dated the seventh day of
December one thousand eight hundred and eighty one with the present improve-
ments applied thereto and whereby the products of combustion will be drawn by
the jet from the nozzle d, and will be purified and condensed before escaping into
the room or building or the said washed products of combustion may be still further
purified and treated by placing trays, provided with suitable reagents, in the
discharge tube.
The purified products of combustion may either escape direct into the room or
may be led back to mingle with the heated air.
In figures 1, 2, 3, 4, 5 and 8, of the drawing I have shewn and have described the
nozzle d, placed vertically in a vertical tube and in figure 6, horizontally. I would
however remark that the nozzle may be placed at any suitable angle or that a
simple jet or jets of water may be provided in any suitable position in the side of
the tube with the object of producing a spiral current or flow of water and of the
air and gases to be treated; or I may employ a multiple nozzle such as that shewn
in figure 7, for producing a spiral current.
Having thus described the nature of my said Invention and suitable means of
carrying the same into effect I would have it understood that what I claim is :-
Firstly. The respective combinations of parts forming modifications of my
improved apparatus for ventilating water closets, urinals, drains, sewers and the
like and for treating smoke, chemical fumes and the like from chimnies and flues,
and stoves, wherein are employed jets of water substantially in the manner and for
the purposes hereinbefore described and illustrated in the respective figures
contained in the annexed Drawing.
Secondly. The employment of a jet or jets of water in combination with forms

page_text: of apparatus such as are herein described and illustrated and operating substantially
in the manner and for the purposes indicated.
In witness whereof I the said Thomas Rowan have hereto set my hand and
seal this eighteenth day of July in the year of our Lord one thousand
eight hundred and eighty two.
