PROVISIONAL SPECIFICATION.
An Improved Sanitary Arrangement for Automatically Disinfecting
Water Closets, Urinals, or other Noxious Places.
I. SAMUEL ALBERT JOHNSON of 225 High Street Poplar, London E. do
hereby declare the nature of this invention to be as follows:-
I provide a vessel of circular or other shape formed with two chambers, the
larger or upper chamber is intended to hold the bulk of the disinfecting matter and
the lower or smaller chamber to contain the required quantity to be used each time
the flushing takes place; leading to the lower or smaller chamber a suction pipe is
provided which empties the lower chamber each time that the closet or other
receptacle or place is flushed, this lower chamber is shut off from the upper
chamber by means of a floating valve placed in the centre of the division plate
which separates the two chambers, and shuts when the operation of emptying the
contents of the lower chamber is going on, thereby uniformly regulating the
desired quantity necessary for effecting the particular object desired.
The lower or smaller chamber is provided with a small air pipe leading
outwardly at the top of the upper chamber. A further small pipe is also provided
leading into the centre of the flushing pipe of the water-closet or other receptacle
or place requiring to be disinfected, and having a lip upon it to catch a similar
amount of liquid to that withdrawn, which is re-supplied to the upper chamber and
therefore it is kept uniformly full.
The disinfecting material or matter I purpose employing is intended to be
enclosed in a bag made of asbestos or other suitable material suspended by means
of a brass screw from the centre of the cap of the upper chamber. The particular
class of disinfectant I may prefer to employ would be in a highly concentrated
form, such as permanganate of potash or other suitable material as will gradually
mix or combine with the water by which it is surrounded.
The said disinfectant when once supplied will be found to last for a long period
and when it is required to be replenished, this can be readily done by simply
removing the cap of the vessel and recharging same.

An Improved Sanitary Arrangement for Automatically Disinfecting
Water Closets, Urinals, or other Noxious Places.
I SAMUEL ALBERT JOHNSON, of 225, High Street, Poplar, London, 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 :-
My invention relates to an improved sanitary arrangement for automatically
disinfecting water closets, urinals or the like, and has for its object to automatically
disinfect water closets or the like by causing a predetermined quantity of
disinfecting or deodorizing liquid to mingle with the downflush at each operation
of flushing, the whole performed in a novel and effective manner.
According to my invention I provide a vessel of circular or other shape formed
with two chambers, the larger or upper chamber intended to hold the bulk of the
disinfecting matter, and the lower or smaller chamber to contain the required
quantity to be used each time the flushing takes place. Leading to the lower or

page_text: smaller chamber a suction pipe is provided, which empties the lower chamber each
time that the closet, urinal or other receptacle or place is flushed, this lower
chamber is shut off from the upper chamber by means of a floating valve, placed
in the centre of the division plate, which separates the two chambers and closes
when the operation of emptying the contents of the lower chamber is going on,
thereby uniformly regulating the desired quantity necessary for effecting the
particular object desired.
The lower or smaller chamber is provided with a small air pipe leading outwardly
at the top of the upper chamber. A further small pipe is also provided leading
into the side of the flushing pipe of the water closet or the like, requiring to be
disinfected (as from time to time needed) and having a lip upon it to catch a
similar amount of liquid to that withdrawn, which is in turn resupplied to the upper
chamber, the latter being therefore uniformly full.
The disinfecting material or matter I propose employing is enclosed in a bag
made preferably of asbestos or other like or suitable material for the purpose,
suspended by means of a brass screw from the centre of the cap of the upper
chamber. The particular class of disinfectant I prefer to employ would be in a
highly concentrated form, such as permanganate of potash or other suitable
material that will gradually mix or combine with the surrounding water. The said
disinfectant when once supplied will be found to last for a long period and when it
is found necessary to replenish the same, it can be readily done by simply removing
the cap of the vessel for recharging.
In the accompanying drawings
Fig. 1, shows a sectional view of the apparatus as fitted to and in connection
with an ordinary "flush pipe" direct from the main tank or cistern, without the
intervention of the "waste water regulator
"
Fig. 2 being a section view of another form of apparatus somewhat similar in
action to that of Fig. 1, and may be employed where waste water regulators" are
in use.
A. is a small bag of asbestos, canvas, or other suitable material, in which the
necessary disinfecting or deodorising property, either in a solid, crystalline or other
highly concentrated form is deposited, and of such a nature as to be readily and
easily soluble in water, such as permanganate of potash or other substance or
matter that I may find in practice most suitable to use for the particular purpose
intended. B. is a cap, which may have a screw-thread formed on its lower part
and be capable of being screwed into the neck of the upper or larger chamber C,
and to which the bag of asbestos or the like is suspended or held in position. A
smaller or lower chamber D is connected with and forms part of the said upper
chamber C, by means of a division plate C. A suction tube or pipe E, is provided
as shown, with a coupling piece F, which is screwed or fitted into the upper
chamber C, likewise to the down or flush pipe G, and through and into which the
upper portion of the suction pipe E protrudes.
The lower chamber D, is at times shut off from the upper chamber C, by means
of a small floating valve H, which has a seating and guard H provided for it to
work in, formed in and on the division plate C₁, so that at each operation which
takes place when the downflush of water occurs, the quantity of disinfecting fluid
that has been permitted to pass into the lower chamber D, is exhausted or taken
therefrom through the medium of the suction tube or pipe E, and issues from the
projecting or dip end thereof as at J, and freely intermingles with the down flush
of water occurring in the pipe G. The terminal portion of the coupling piece F, is
formed with an open lip as at K, for the purpose of catching a similar quantity of
water, at each flushing operation and resupplying the upper chamber C, to that
amount of the disinfecting fluid withdrawn from the lower chamber D.
Referring to Fig. 2, in lieu of suspending the bulk of the concentrated
disinfectant, such as inay be preferred to be used, in a bag of asbestos (or other
like material) in manner previously described, I propose to place a certain quantity
of highly concentrated disinfecting substance in a crystalline or other form within

page_text: the upper chamber C, Fig. 2) so as to rest upon a layer of asbestos or the like as.
shown at C therein, and placed in position upon the upper surface of the division
plate C', which separates the upper chamber C, from the lower chamber D. The
disinfecting substance or matter by the aid of water admitted from time to time in
the said upper chamber C, (and in manner exactly similar to that described and
shown at Fig. 1) will readily percolate through the said layer of asbestos Cin
sufficient quantity to charge and resupply the lower chamber D, the contents of
which would at each flushing operation be abstracted through the medium of the
suction pipe E and dip end J. L is a small air pipe leading outwardly at the top.
of the upper chamber C, and connected with the lower or smaller chamber D in
like manner to that shown at Fig. 1.
I am well aware that there have been other attempts made to give or discharge.
a disinfecting liquid or property so as to mix either with the down flush of water
or to be placed in the cistern or otherwise, and in such like or similar disinfecting
arrangements whereby the use of such a disinfectant as permanganate of potash
when employed, the passages have been found to get choked or clogged and the
supply materially retarded. But by my present invention I provide a very simple
improved sanitary arrangement for automatically and effectively discharging or
distributing in a liquid form, certain disinfecting or deodorising properties as may
be preferred and in no way liable to derangement.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved arrangement and general combination of parts and use of
appliances and the employment of same for automatically disinfecting water
closets, lavatories and the like in manner substantially and for the particular
purpose described and illustrated by the drawings.
2. The use or employment of a bag of asbestos cloth or such like or suitable
imperishable material or materials suspended within an upper or division chamber
forming part of the apparatus, to receive a certain quantity of a suitable highly
concentrated disinfecting substance or property when in.use, such as permanganate
of potash or other disinfectant in a crystalline or other form, capable of being
gradually and readily converted into solution with water, substantially as and for
the purpose described and illustrated by the drawing as at Fig. 1.
"
3. The general combination of a lower chamber having a "floating valve'
capable of regulating the required supply or amount of disinfecting fluid received
from the upper or division chamber and contained in the lower chamber ready at
each successive operation when the down flushing takes place to be discharged
therefrom by means of a suction pipe, with a supply pipe for re-supplying the
upper chamber with water at each operation in manner substantially as and for the
purpose described and illustrated by the drawings.
4. The alternative form or class of automatic disinfecting apparatus (as herein
referred to and shown in the drawing by Fig. 2) wherein the disinfecting substance
is placed within the upper or divisional chamber upon a sheet or layer of asbestos
cloth or such like material fitted in position upon the upper surface of a division.
plate, substantially as described and illustrated by the drawing.
