in the Borough of Southwark, Surgeon, for the Invention of “Iм-
PROVEMENTS IN MEANS OF DISINFECTING WATERCLOSETS, URINALS, AS WELL
10 GS AND OTHER CONDUITS AND APPARATUS THEREFOR.
"
Sealed the 15th December 1871, and dated the 17th July 1871.
PROVISIONAL SPECIFICATION left by the said Alfred Gardiner Brown
at the Office of the Commissioners of Patents, with his Petition,
on the 17th July 1871.
I, ALFRED GARDINER BROWN, of 63, Trinity Square, in the Borough
of Southwark, Surgeon, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MEANS OF DISINFECTING WATERCLOSETS, URINALS,
AS WELL AS GUTTERS AND OTHER CONDUITS, AND APPARATUS THEREFOR," to be as
follows:
:-
In order to prevent smells from arising from waterclosets, urinals,
latrines, or other similar conduits, I provide a casing, vessel, or reservoir
of either parallelopiped or any other suitable shape, which I fix to or
connect with any appropriate part of the watercloset, urinal, or conduit

page_text: or fit in any other suitable place or situation. This vessel or reservoir
I fill with any disinfecting or deodorizing fluid, and furnish with
suitable apertures, through one or more of which I cause a small pipe
or tube of appropriate length to pass into the downflow or supply pipe,
by which the cleansing water is supplied to the watercloset or urinal.
In some convenient part of this. small pipe or tube a widening or
dilatation may be made, whereby the disinfecting liquid is delayed in
its passage to the downflow or supply pipe. I so connect the small
pipe or tube by means of stuffing boxes, flanges, or any other of the
well-known kinds or descriptions of joints with the downflow or supply
pipe, that whenever water shall be caused to pass through the downflow
pipe towards or into the part or parts of the watercloset, urinal, or
conduit to be cleansed, some of the disinfecting or deodorising fluid
contained in the vessel or reservoir shall pass through the small pipe or
tube into the supply or downflow pipe, so that by commingling with
the cleansing water such disinfecting or deodorizing liquid shall act
simultaneously therewith and contribute to the cleansing of the water-
closet, urinal, gutter, or conduit, so as to counteract any offensive smells
or effluvium.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Gardiner Brown in the Great Seal Patent
Office on the 16th January 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
GARDINER BROWN, of 63, Trinity Square, in the Borough of Southwark,
Surgeon, send greeting.

and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN MEANS OF DISINFECTING WATERCLOSETS, URINALS, AS WELL AS GUTTERS AND
OTHER CONDUITS, AND APPARATUS THEREFOR,' upon the condition (amongst
others) that I, the said Alfred Gardiner Brown, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Alfred Gardiner Brown, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement and accompanying Sheet of
Drawings:-
In order to prevent smells from arising from waterclosets, urinals,
latrines, or other similar conduits I provide a casing, vessel, or reservoir
of either parallelopiped or any other suitable shape, which I fix to or
connect with any appropriate part of the watercloset, urinal, or conduit,
or fit in any other suitable place or situation. This vessel or reservoir
I fill with any disinfecting or deodorizing fluid, and furnish with suitable
apertures, through one or more of which I cause a small pipe or tube of
appropriate length to pass into the downflow or supply pipe by which
the cleansing water is supplied to the watercloset or urinal. In some
convenient part of this small pipe or tube a widening or dilatation may
be made, whereby the disinfecting liquid is delayed in its passage to the
downflow or supply pipe. I so connect the small pipe or tube, by means
of stuffing boxes, flanges, or any other of the well-known kinds or
descriptions of joints with the downflow or supply pipe, that whenever
water shall be caused to pass through the downflow pipe towards or
into the part or parts of the watercloset, urinal, or conduit to be cleansed
some of the disinfecting or deodorizing fluid contained in the vessel or
reservoir shall pass through the small pipe or tube into the supply or
downflow pipe, so that by commingling with the cleansing water such
disinfecting or deoderizing liquid shall act simultaneously therewith and
contribute to the cleansing of the watercloset, urinal, gutter, or conduit,
'so as to counteract any offensive smells or effluvia.

page_text: In the annexed Sheet of Drawings I have shewn several arrangements
of reservoirs and tubes for disinfecting or deodorizing waterclosets in
conformity with my method, as herein-before described. In the whole
of these Drawings the same letters always denote identical parts, or such
parts as are designed to discharge identical duties or functions, and the
whole of the Figures are drawn as diagrams generally representing
sectional elevations of the apparatus constructed according to my
Invention, only one line being in each case given for the thickness of
the sides of reservoirs or other vessels or of pipes or tubes.
In Figure 1, A is the reservoir or vessel containing the deodorizing or
disinfecting fluid; B is the infusion pipe or measuring tube, the bottom
part B of which may be either straight, C shaped, or coiled, and is
furnished with the suction hole E through which the disinfecting fluid
enters the pipe; C is the spout leading into the downflow or supply
pipe D; F is the opening or hood through which the deodorizing
reservoir or vessel A is fed. As soon as the downflow or supply pipe D
is filled with water this water acts by suction upon the spout C so as
to draw over the disinfectant into the pipe D.
.
In Figure 2 I have shewn a variation of the arrangement Figure 1,
in which a portion of the infusion tube or measuring tube B is dis-
pensed with. In this case the open bottom end of the pipe B is dipped
into the deodorizing or disinfecting fluid. The working of the apparatus
is identical with that of the one shewn in Figure 1.
In Figure 3 I have shewn a different arrangement in which the
pipe B dipped into the disinfecting fluid is introduced into the down-
flow or supply pipe D, and the spout C entering into the same pipe is
connected by means of an intermediate tube B with the reservoir A.
Thus as soon as the cleansing water enters the downflow pipe D it
fills forthwith the pipe B, and commingling with the deodorizing or
disinfecting fluid in the reservoir at once raises the level thereof, and
thence issuing into the intermediate tube B¹ enters the downflow pipe D
through the spout C, and thereby effects the deodorizing action.
In Figure 4 a similar arrangement to Figure 3 is shewn. In this
case the pipe B connects the downflow or supply pipe B with the
reservoir A in a manner analogous to Figure 3, but instead of being
dipped directly in the disinfecting or deodorizing fluid its bottom
'part E is perforated, and a perforated diaphragm or sieve plate G is so
placed above it as to cause the water coming from the downflow pipe D

page_text: to commingle but at a slow rate and in a diffused manner with the
disinfecting fluid. The pipe B in this instance discharges the same
duties as in Figure 3.
In Figure 5 a solid diaphragm or diffusion plate G is introduced in
lieu of the sieve or perforated plate G, Figure 4, and the reservoir or
vessel A is fed by means of a tube H having its bottom end or spout
below the diaphragm G. The connecting pipe B here terminates above
the diaphragm, and the contents of the reservoir A commingled with the
water are discharged by the spout C in the same manner as in the two
previous arrangements.
In Figure 6 I have shewn in what manner I prefer to connect the
apparatus constructed according to my Invention with a supply or
cleansing pipe of which a portion is horizontal. In this case the pipe B
with the perforated end E enters the supply or cleansing pipe D in the
manner shewn. By means of this pipe B the water is commingled with
the contents of the reservoir A and proceeds into the cleansing pipe D
through the intermediate tube B¹, as in the two previous instances,
immediately the valve K is opened, by which the water is admitted
through the supply or cleansing pipe D to the pan M, of which only a
small portion is shewn here. In every other respect the action of the
apparatus according to this last ärrangement is identical with that
described heretoforc.
In Figure 7 I have shewn a different mode of connecting an apparatus
constructed according to my Invention with a supply or cleansing pipe
leading directly to the watercloset. By means of a partition I an air
chamber J is here separated from the reservoir A, and from this chamber
the tube B' with the spout C leads into the cleansing pipe D. In the
pipe B fed through the pin hole E from the reservoir, as in the arrange-
ment shewn in Figure 1, I introduce a partition with an aperture G.
Thus upon the opening of the valve K the water rises into the air
chamber J and thereby the fluid in the tubes b, b', will be pushed back
and partly discharged into the reservoir at L. Upon the closing of the
valve K the water in the air chamber J will flow back towards the
closet pan M and draw over the fluid which from the pipe B has flowed
through the aperture G into and b¹ in the interval, and this fluid
will thence issue through into J and from the air chamber through
B' into D.

page_text: In Figure 8 the reservoir A is shewn in elevation, and the rest of the
apparatus in section. In this arrangement the tube B leading from the
closet pipe D to the reservoir A is dilated at N and furnished with a
valve O. As soon as the cleansing water is admitted into the pipe D
through the valve K, the valve O will be pushed upwards by the water
and thus preclude the latter from entering the reservoir until after the
closing of the valve D. In every other respect the working of the
apparatus in this instance is similar to that of previously described
arrangements.
Having now described the nature of my said Invention and illus-
trated the same in the accompanying Sheet of Drawings, I wish it to be
understood that I do not claim the use of reservoirs or vessels of any
particular shape for disinfecting or deodorizing waterclosets, urinals,
or other conduits; but what I do claim is,
First. The use or employment of pipes or tubes connecting a reservoir
or vessel containing disinfecting or deodorizing liquid with the down-
flow or supply pipe of waterclosets, urinals, or other similar conduits,
in the manner herein-before described and illustrated in the accom-
panying Sheet of Drawings.
Second. The use or employment of the mode or manner described
herein-before, and illustrated chiefly in Figures 7 and 8 of the accom-
panying Sheet of Drawings, of securing the disinfection of waterclosets
or other conduits, and at the same time preventing the overflowing of
the liquid in the disinfecting reservoir or vessel.
In witness whereof, I, the said Alfred Gardiner Brown, have here-
unto set my hand and seal, this Tenth day of January, in the
year of our Lord One thousand eight hundred and seventy-one.
