PROVISIONAL SPECIFICATION.
Improved Means for Deodorising and Disinfecting Water Closets,
Urinals, and the like.
I, DONALD BUCHAN of 67 Garford Street, Poplar, London, E. Engineer do
hereby declare the nature of this invention to be as follows:-
In accordance with my invention, I provide ready and efficient means whereby I
effect, in the operation of flushing water closets, urinals &c., the introduction, along
with the flush water, of any suitable deodorising and disinfecting agent. This
latter is contained in any suitable reservoir or receptacle conveniently disposed
relatively to the water closet, uriual or the like, and is connected by means of a
syphon tube, with a syphon chamber or receptacle the lower end of which
communicates with the flushing pipe.
I so arrange the device, according to my invention, as to ensure that upon each
pull upon the lever of the closet or urinal flush, a proportionate quantity, and no
more, of the liquid disinfecting or deodorising agent contained in the first above
referred to receptacle is syphoned out from the latter and entering the second (or
syphon) chamber or receptacle above referred to and commingling therein, and
with the flushing water the latter with its dose or portion of deodorising or
disinfecting liquid is discharged through the closet or urinal flush pipe. The
device, according to my invention, is not only readily and economically fitted for
use but I also ensure that the requisite quantity only, and no waste, of the
disinfecting or deodorising agent or agents takes place.
Dated this 13th day of November 1893.

Improved Means for Deodorising and Disinfecting Water Closets,
Urinals, and the like.
I, DONALD BUCHAN of 67 Garford Street Poplar, London, 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:
My invention relates to ready and efficient means whereby I effect in the
operation of flushing water closets, urinals &c. the introduction, along with the
flush water, of any suitable deodorising and disinfecting agent.
And in order that my invention may be more fully understood I have appended
the accompanying drawing which shows a sectional elevational view of the flush
water containing tank or cistern with my improved device fitted thereto.
In accordance with my invention I dispose in the centre of the tank or cistern a
the siphon chamber b having projections formed around same, and also a junction
pipe on one of its sides at the lower end, over the mouth of which fits the plug c,
the end of the chamber b being connected to the discharge pipe p in the usual
manner. Over and around the syphon chamber b I place the cover d with a
perforation in the top of same to which the syphon tube e is connected and
D....31

page_text: through which passes the deodorising and disinfecting fluid, consisting of say
1 portion of any deodorising and disinfecting agent to 2 portions of water which is
contained in a bottle, jar or other transparent vessel f, attached to the tank in any
convenient position relative thereto, having a protective cage or cover g. The object
of having a transparent container is to allow of readily discerning when the
container requires recharging.
The operation of my improved device is as follows, that is to say :—'
-When
the ordinary flushing lever his pulled and the plug c raised, the flush water in the
cistern, rushes in the lower end of the syphon chamber 6 (as indicated by the
arrow) which causes suction and by the syphonic action resulting, a small portion
or dose of the deodorising or disinfecting agent is drawn simultaneously through
the syphon tube e and passing down the chamber 6 commingles itself with the
flush water before reaching the water closet, urinal or the like to which my
improved device is adapted.
The device according to my invention, is not only readily and economically fitted
for use, but I also ensure that the requisite quantity only is drawn and no waste of
the deodorising and disinfecting agent takes place.
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 :-
The improved means for deodorising and disinfecting water closets, urinals and
the like, substantially as described and shewn in the accompanying drawing.
Dated this 27th day of March 1894.
