I HENRY SHEPLEY BOOTH, of the firm of H. S. Booth & Co., of 6 Hall Street,
Manchester, in the County of Lancaster, Packers, do hereby declare the nature of this
Invention to be as follows:-
My said Invention relates to an improved method of and means for removing
ofluvia from water closets and relates chiefly to means whereby the inflow of water
under pressure from the main or from another source, into the flushing cistern is
automatically utilised to draw or force the confined air and effluvia from the closet and
expel the same, so that each time the closet is used the air in the closet is automatically
renewed by the act of flushing the pan. In a suitable arrangement for carrying my
invention into effect, 1 place suitable means for drawing or forcing air, such for
example as an ejector, above or in juxta-position to the flushing cistern and I conduct
the supply pipe from the main or other source to the said ejector. The tap, cock or
valve governing the water supply is regulated by a floating ball in the flushing cistern
in the usual manner so that when the cock is opened by the falling of the ball, the
water rushes through the ejector on its way to the flushing cistern. The feed end of
the ejector opens into the closet while the delivery end is directed to the outer
atmosphere or to an upcast ventilating shaft or flue, suitable air pipes or passages
being combined with the ejector. The vitiated air and the water pass together through
the ejector the water being directed into the flushing cistern and the air expelled as
aforesaid. The foul air thus removed is replaced by fresh air through suitable
ventilating passages although such need not of necessity be provided. "In a closet
fitted with my invention the occupant in flushing the pan empties the flushing cistern
and thus opens the supply cock, the supply thereupon rushing through the ejector and
simultaneously filling the flushing cistern and removing the foul air in the manner
described. It will be understood that I do not confine myself to an ejector for
removing the foul air, as a fan or blower either directly acted upon by the supply
pressure or by means of a small turbine or water wheel might be used.

open to the atmosphere in the closet and the outer end to the outer atmosphere or to
an upcast shaft or ventilating space or passage. The sprayed water falls into the said
knee in the pipe k and from thence runs into the flush cistern. The apparatus when
fitted up in the described manner operates as follows. When the closet has been
used and it is desired to flush the pan the ordinary handle or any other suitable
handle is pulled and the contents of the cistern e rush into and flush the pan of the
'closet a.
The cistern c being thus emptied the ball or float falls and by raising the
free end e¹ of the lever e allows the valve d to be opened by the pressure of water in
the supply pipe h. The water thus passes through the valve d and has access to the
pipe and spray nozzle j. The pressure of water passing through the nozzle creates
a fine spray which flies down the tube and settling in the knee runs into the
cistern c and in a stated time restores the level of water in the said cistern. The
aforesaid forcing of the water through the spray nozzle aspirator j creates a current
of air down the tube as shown by the arrows the sprayed water and air being
mingled until the knee is reached at which point the water runs into the
cistern whilst the air current proceeds up the inclined continuation of the tube kand
is discharged into the outer atmosphere or into a shaft or air passage. The water in
the knee seals the water outlet to the cistern so that the air current cannot escape
there. The air current thus induced in the tube k draws into the tube all of the foul
and effluvia laden atmosphere in the closet and discharges it outside in the manner
shown and described. The foul air thus drawn away is replaced by fresh
from without entering through ventilating holes in the wall, door floor window o
other part or parts-if such admission holes are found to be requisite. It will thu:
be seen that by the mere act of flushing the pan the user of the closet at the sam
time automatically ventilates the apartment so that no odour is perceived by the nex
occupant. The arrangement shape and so forth of the foul air discharging tube and
spray are subject to many modifications, suggested by the situation of the close
flushing cistern and for other reasons. For example in Fig. 3 when like parts ar
similarly lettered the tube is shown of a U shape and is placed at one side of th
cistern instead of above it as in Fig. 1. The arrangement of valve d is also slightl

applicable to self-flushing closets in which the flushing takes place upon rising from a
hinged seat or treading upon a hinged threshold or opening or shutting a door all of.
these methods of flushing being now in common use. The invention may also be
used in connection with enclosed urinals which are periodically flushed. Instead of
a spray I might employ a fan or other air propeller which would be driven by the
rush of the supply to the cistern and so expel the foul air from the closet. Although
I have described the supply to the spray nozzle as being governed by a ball or float
and lever operating a valve, it will be understood that any known means other than
the said ball and valve for creating the rush of supply water to the cistern would be
equally applicable in conjunction with my invention.
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:-
(1) Automatically ventilating water closets by utilising the rush of supply water
under pressure from the main or other suitable source, to the flushing cistern the said
supply water being caused to pass through a spray aspirator or to operate any other
suitable air drawing or forcing apparatus situated in or placed in connection with a
ventilating tube through which the foul air is automatically discharged from the closet
at the times when the pan of the water closet is flushed.
(2) The general arrangement and combination of parts comprising the apparatus
for automatically expelling foul air from water closets on the occasions of the pan being
flushed the said apparatus consisting of a ventilating tube and a spray or other air
forcing or drawing apparatus in conjunction with means for directing the water
supply to the flushing cistern through the said spray or other air forcing apparatus
and via the ventilating tube to the cistern, the foul air in the closet being thus drawn
in at one end of the ventilating tube and discharged at the other end into the outer
air or other convenient place substantially as herein before described and shown.

page_text: To render my invention perfectly clear I will now proceed to describe the same
with reference to the accompanying sheet of illustrative drawings...
Fig. 1 shows an enclosed space representing a water closet. a is the pan trap and
seat. bis the flushing pipe leading the water from the flushing cistern c. In the
present instance I have shown the valve d through which the water under pressure
passes from the main or other source, as being outside of the flush cistern and as being
operated from a ball or float in the cistern, the said ball or float not appearing in the
drawing as its action and construction is well known. The valve dis shown in
section to an enlarged scale at Fig. 2. The lever e is supposed to extend from the
said ball or float and is pivotted at so that the free end e presses down upon the
stem g of the valve d when the flush cistern is full and the float raised to its highest
position. The valve d is thus held closed against the pressure of water in the supply
pipe so that no more water can pass to the cistern. From the casing of the valve d
and situated above the valve disc there extends a branch which is connected to a
pipe which is led into the mouth of a foul air discharging tube k. The end of the
pipe is fitted with a spray nozzle j, of the ordinary construction of such spray nozzles
as are used for ventilating and for other purposes. The foul air discharge tube k is
constructed in the manner shown, or in any other suitable manner. As shown in the
drawing it is made with a knee the tube sloping downwards to and upwards from
the said knee so that no water shall escape or be thrown from either end of the tube k,
both ends of the said tube being open, the inner end where the spray is situated being
open to the atmosphere in the closet and the outer end to the outer atmosphere or to
an upeast shaft or ventilating space or passage. The sprayed water falls into the said
knee in the pipe k and from thence runs into the flush cistern. The apparatus when
fitted up in the described manner operates as follows. When the closet has been
used and it is desired to flush the pan the ordinary handle or any other suitable
handle is pulled and the contents of the cistern e rush into and flush the pan of the
closet a.
The cistern c being thus emptied the ball or float falls and by raising the
free end of the lever e allows the valve d to be opened by the pressure of water in
the supply pipe h. The water thus passes through the valve d and has access to the
pipe and spray nozzle j. The pressure of water passing through the nozzle creates
a fine spray which flies down the tube and settling in the knee k' runs into the
cistern c and in a stated time restores the level of water in the said cistern. The
aforesaid forcing of the water through the spray nozzle aspirator j creates a current
of air down the tube as shown by the arrows the sprayed water and air being
mingled until the knee is reached at which point the water runs into the
cistern whilst the air current proceeds up the inclined continuation of the tube kand
is discharged into the outer atmosphere or into a shaft or air passage. The water in
the knee seals the water outlet to the cistern so that the air current cannot escape
there. The air current thus induced in the tube & draws into the tube all of the foul
and effluvia laden atmosphere in the closet and discharges it outside in the manner
shown and described: The foul air thus drawn away is replaced by fresh
from without entering through ventilating holes in the wall, door floor window or
other part or parts-if such admission holes are found to be requisite. It will thus
be seen that by the mere act of flushing the pan the user of the closet at the same
time automatically ventilates the apartment so that no odour is perceived by the next
occupant. The arrangement shape and so forth of the foul air discharging tube and
spray are subject to many modifications, suggested by the situation of the closet
flushing cistern and for other reasons. For example in Fig. 3 when like parts are
similarly lettered the tube is shown of a U shape and is placed at one side of the
cistern instead of above it as in Fig. 1. The arrangement of valve d is also slightly
different from that in Fig. 1 the valve stem being horizontal instead of vertical."
The water from the knee k¹ runs to the cistern c through a pipo m. These slight
differences however make no changes in the principle of my invention since as I have
said the arrangement depends largely upon circumstances. It will also be evident
that my invention is applicable both to the old and to the new types of water closets

page_text: and that it can be applied at a small cost to existing water closets. It is also
applicable to self-flushing closets in which the flushing takes place upon rising from a
hinged seat or treading upon a hinged threshold or opening or shutting a door all of
these methods of flushing being now in common use. The invention may also be
used in connection with enclosed urinals which are periodically flushed. Instead of
a spray I might employ a fan or other air propeller which would be driven by the
rush of the supply to the cistern and so expel the foul air from the closet. Although
I have described the supply to the spray nozzle as being governed by a.ball or float
and lever operating a valve, it will be understood that any known means other than
the said ball and valve for creating the rush of supply water to the cistern would be

claim is :-
(1) Automatically ventilating water closets by utilising the rush of supply water
under pressure from the main or other suitable source, to the flushing cistern the said
supply water being caused to pass through a spray aspirator or to operate any other
suitable air drawing or forcing apparatus situated in or placed in connection with a
ventilating tube through which the foul air is automatically discharged from the closet
at the times when the pan of the water closet is flushed.
(2) The general arrangement and combination of parts comprising the apparatus
for automatically expelling foul air from water closets on the occasions of the pan being
flushed the said apparatus consisting of a ventilating tube and a spray or other air
forcing or drawing apparatus in conjunction with means for directing the water
supply to the flushing cistern through the said spray or other air forcing apparatus
and via the ventilating tube to the cistern, the foul air in the closet being thus drawn
in at one end of the ventilating tube and discharged at the other end into the outer
air or other convenient place substantially as herein before described and shown.
