AN IMPROVEMENT IN WATER CLOSET DISINFECTING APPARATUS
Year: 1884

page_text: I JOSEPH COUCH KENT of Bedfont in the County of Middlesex Gentleman,
do hereby declare the nature of the said invention for "AN IMPROVEMENT IN
WATER CLOSET DISINFECTING APPARATUS" to bo as follows:-
My Invention relates to improved construction of combined water closet and
disinfecting apparatus for automatically impregnating the water used for flushing
the closet with a disinfectant material such as permanganate of potash.
This apparatus consists of a globular or other shaped vessel in the lower part
of which the said material is contained beneath a perforated diaphragm, suitable
inlet and outlet pipes projecting into the vessel and terminating just above the
diaphragm, the inlet tube being branched into the pipo supplying the flushing
water to the closet and the outlet pipe discharging into the closet basin so that
a portion of the flushing water passes through the disinfectant vessel. A charging
tube by which the disinfectant material is introduced leads down through the top
of the vessel to the space beneath the diaphragm.
The invention consists in casting the above mentioned vessel in one piece with
the pan or basin of the closet the two forming one complete combined apparatus
so that no separate fixing is required and the proper relative height of the vessel
to the height of the closet pan is ensured without adjustment so that the proper
proportion of the flushing water shall always pass through the vessel.

COMPLETE SPECIFICATION.
I JOSEPH COUCH KENT of Bedfont in the County of Middlesex, Gentleman
do hereby declare the nature of the said invention for "AN IMPROVEMENT IN
WATER CLOSET DISINFECTING APPARATUS," and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:
My Invention consists in the construction of a combined water closet basin or
pan and disinfecting apparatus for automatically impregnating the water used for
Alushing the closet with a disinfectant material, such for instance as permanganate
of potash.
The disinfecting apparatus consists of a hollow vessel, in the lower part of
which the disinfectant is contained beneath a perforated diaphragm, suitable
inlet and outlet pipes projecting into the vessel and terminating just above the
diaphragm. Both these pipes are branched into the arm of the pan with which
-the pipe supplying the flushing water to the closet connects, and when the closet
valve is opened to flush the closet, a portion of the water passes through one of
the tubes into the disinfectant vessel where it dissolves the disinfecting material
and passes off through the other tube and is discharged with the incoming water
into the pan. A charging tube by which the disinfectant material is introduced,
leads down through the top of the vessel to the space beneath the diaphragm.
According to my Invention, the vessel for containing the disinfectant, is made
of earthenware and in one piece with the pan or basin of the closet, the two
forming one complete combined apparatus so that no separate fixing is required
and the proper relative height of the vessel to the height of the closet pan is
ensured without adjustment so that the proper proportion of the flushing water
shall always pass through the vessel.
In the accompanying drawings, figure 1 shows a plan, and figure 2 a section on
line a-b figure 1 of the apparatus constructed according to my Invention.
a is the closet pan and b the vessel for containing the disinfectant, the two
being made in one piece as above mentioned. c is the arın of the pan to which
the water supply pipe is attached, and d and e the two pipes by which the water
circulates through the vessel b, both attached to the arm c and connecting with
vessel b above the diaphragm 6' in the latter. These pipes are inserted into
sockets and on the arm c of the pan and on vessel b; the joints are
rendered watertight by a sheathing of indiarubber or otherwise in the usual way
of making such joints. The inlet pipe d is attached to the lower part of the
arm c and it projects into said arm and its end is bevelled (as seen more clearly
in figure 1) to ensure that the required quantity of the incoming water shall pass
through vessel b. The outlet pipe e which is of smaller area than the pipe & is
attached at the upper part of arm c and its orifice is contracted at e¹ so that the
force of the incoming water shall not prevent the water circulating through
vessel b. bis the diaphragm in the vessel b also made of earthenware, and g
the tube through which the disinfectant is introduced. This tube g is closed by
a cap g screwing onto a neck 6 cast on the top of vessel b and forming an air
vessel which determines the circulation of the water through said vessel b.

page_text: In constructing my combined apparatus, the edges of the disinfectant vessel
containing the diaphragm are united to the pan in the ordinary way so as when
baked to constitute one piece of earthenware.
By means of my Invention the difficulty heretofore experienced where a separate
vessel is employed, is avoided, and the operation of the apparatus is ensured
without the necessity of any special adjustment.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed, I declare that what
I claim is
The manufacture of the combined water closet pan or basin and disinfectant
vessel in one piece of earthenware, substantially as described for the purposes
specified.
