An Improved Sanitary Method for the Prevention and Non-return
of Sewer or other Gas in Ordinary Dwellings or Habitations
B from Water Closets, Lavatories, and other Conveniences and in
Disinfecting the Same.
I SAMUEL ALBERT JOHNSON of 24 Glengall Road Millwall in the Parish of Poplar E.
Engineer, do hereby declare the nature of this invention to be as follows:-
By my
method with any class of Water Closet, Lavatory or otherwise that is or may
be and in addition to the ordinary mode of "flushing" by water or otherwise, I
provide thereto a Seperate Chamber, receptacle or vessel so as to contain or hold a
suitable class of Oil or other matter of a greasy nature as likewise when desired a
suitable disenfectant and by preference those whose specific gravities readily mixes
with the Oil or greasy matter as proposed for the specific purpose intended as hereafter
described.
In the case of an ordinary Water Closet or other convenience when and immediately
"flushed
upon its being
or cleansed I so provide and mechanically arrange
automatically in action therewith that a certain quantity or proportion of the Oil or
greasy substance or matter shall with its suitable disenfectant as may be found
desirable or otherwise be so disposed as to entirely cover the entire surface of the
chamber or liquid receptacle surface and so seal and securely prevent any upward rise
of noxious sewer gas or gases or other effluvia from time to time when either at rest
or in action as the case may be.

Disinfecting the same.
I, SAMUEL ALBERT JOHNSON of 24 Glengall Road, Millwall in the Parish of Poplar, E.
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This Invention consists of an Improved Sanitary method or means for the purpose
disenfecting Water Closets or other similar conveniences and in "Sealing" or securing
and effectually preventing the escape of noxious gases or other effluvia returning into
the dwelling or other habitation therefrom.
By my method with any class of Water Closet that is or may be known or in use
and in addition to the ordinary mode of "flushing" by water or otherwise as the case
may be, I provide in connection with the "flushing" or storage chamber or receptacle
or attached thereto, a further separate chamber, receptacle or vessel of a necessary
capacity, so as to hold or contain a suitable class of oil or other matter of a greasy or
similar nature or substance as may be preferred and found most suitable, either separate
or in combination as may be desired with any suitable disenfectant or disenfectants,
which would be capable of readily combining therewith and by preference of that class
whose specific gravity render them capable of freely mixing with the Oil or greasy
matter for the purpose intended and as hereafter described.
In the case of an ordinary Water Closet or convenience, the Oil or greasy matter
or compound together with its admixture of any suitable disenfectant as may be found
preferable contained in the separate or distinct chamber or receptacle to that of the
Water supply or flushing chamber; the said seperate chamber in which the Oil or
greasy matter is contained, I take and provide with a down pipe or tube (or tubes)
which by preference may be led or connected with the lower or bottom portion of the
"Soil
or S shaped exit pipe having an opening or openings formed therein, and I
so arrange that immediately after the action of "flushing" the pan has taken place,
that I cause or so provide and arrange in connection therewith or otherwise by any
Simple Mechanical means actuating a crank or levers (or cranks or levers) or similar
or other equivalents, so as to open or release a valve or plug or other suitable means
automatically and thereby instantly act and set free a certain regulated or sufficient
quantity or proportion of the Oil or greasy matter or substance as may be requisite
for my object, which then enters and is caused to descend by its gravity alone, or
otherwise in addition if needed, through the down pipe or tube (or tubes) and enters
into the lower portion of the Soil or S shaped pipe and from thence percolates or
permeates through the water and so ascends and covers or floats upon the entire
liquid surface or portion of the Water level, permitted to remain in the soil or S shaped
pipe after being flushed, and creates as it were a double seal.
It will therefore be seen and found in practice that by the adoption of my method
as herein described wherein the Oil or greasy matter or admixture is permitted,
immediately after the act of "flushing" has taken place, to cause the same to enter in
manner described or otherwise as may be found most desirable and effective for the

page_text: specific purpose, so as to enable it to freely enter and pass through toward the surface
or level and float thereon upon the water remaining in the soil or S shaped pipe, or
otherwise arrange so as to effect the same object and so "seal" and securely prevent
any upward or inward rise or escape of all noxious sewer gas or gases or effluvia from
time to time as the case may be.
In the accompanying drawing I have shewn the general principle and method of
my Invention as adapted and suitable for the purpose of an ordinary or other class of
closet, wherein A is the ordinary flushing or water cistern to which the down or flush
pipe B, is connected. Within the said cistern A, a float C is provided within which
a rod D, is connected to a joint or pivot E at its upper end and freely works with it
and further connected to a lever or beam F, working on a fulcrum G, at the further
end or continuation of the said lever or beam F and at the end of the same a further
rod or spindle H is connected and terminating at the downward end with and con-
nected thereto a valve or plug J is provided. K is a receptacle or oil chamber
intended to contain or hold a sufficient quantity of oil or other matter of a greasy or
similar nature or substance and in combination therewith if desired or thought
necessary with
suitable disenfectant or disenfectants capable of readily combining
therewith, whose specific gravities render them capable of freely mixing with the oil
or greasy matter that may be found most suitable to employ. L, is a down pipe or
tube leading from the oil receptacle or chamber K, toward the lower portion (as may
be preferred or found most desirable) of the Soil or S shaped or other form of pipe as
now, or may be used.
any
It will therefore be seen that upon the hand pull or uprize or other Mechanical
action given, as may be preferred, or in any ordinary way, so as to cause the plug in
the down or cistern water pipe B to be opened and causing the flush as may be so
regulated and provided; but instantly this is or about being completed that C, in
its descent will then act upon, and be so guided by means of the rod Do weigh
upon the surface of the stop washer M at the end of the said rod D, which then
actuates or causes the Lever or beam F by means of the attachments or connections
referred to E, F and H, and acting upon the fulcrum G upon which it works, so as to
lift raise and cause the valve or plug J, and so automatically and continuously at each
action permit of a regulated quantity of oil or greasy matter (and other admixture as
a disenfectant if wished) to flow or trickle into & through the down pipe L and to
so premeate or percolate into and through the water contained in the soil pipe S, and
finally surface and float upon the same as shewn at N, and thereby effectually pre-
venting the return of the Sewer gas and sealing as against the same, likewise
preventing the evaporation of the water therein.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed-I wish it to be understood that I
do not confine myself or lay claim to any particular Mechanical action or manner for
automatically releasing, working or regulating the amount of oil or greasy matter or
compound for the purpose herein described and set forth, which may be effected and
applied in any simple or suitable manner or extent, so as to instantly and automatically
follow the act of "flushing."
I declare that what I claim, is the method or principle for the prevention and non-
return of Sewer or other Gas or Gases from Water Closets and other similar conveniences
by the use or employment of oil or other greasy matter or compound mixed or other-
wise with a suitable and efficient disenfectant or disenfectants and caused to surface
and float upon the water or liquid left in the Soil pan or S pipe after being "flushed"
in manner as may be preferred as herein described and set forth.
