IMPROVEMENTS IN APPARATUS FOR SUPPLYING DISINFECTANTS FOR DISINFECTING WATER- CLOSETS AND FOR OTHER PURPOSES
Year: 1875

page_text: LETTERS PATENT to John Howard, of 4, Linden Grove, Nunhead
Lane, in the County of Surrey, for the Invention of "IMPROVEMENTS
IN APPARATUS FOR SUPPLYING DISINFECTANTS FOR DISINFECTING WATER-
CLOSETS AND FOR OTHER PURPOSES."
Sealed the 14th September 1875, and dated the 15th April 1875.
PROVISIONAL SPECIFICATION left by the said John Howard at the
Office of the Commissioners of Patents, with his Petition, on the
15th April 1875.
I, JOHN HOWARD, of 4, Linden Grove, Nunhead Lane, in the County
of Surrey, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR SUPPLYING DISINFECTANTS FOR DISINFECTING
WATERCLOSETS AND FOR OTHER PURPOSES," to be as follows:-
This Invention has for its object improvements in apparatus for
supplying disinfectants for disinfecting waterclosets and for other
purposes. For this purpose I employ a bottle or vessel placed near the
supply pipe of the closet and supplied with disinfectant. I use a

page_text: disinfectant soluble in water or a highly concentrated fluid or paste.
The bottle or vessel is closed with a stopper and it has two pipes con-
nected with it. At each action of the closet a regulated quantity of
water is injected by one pipe into the bottle or vessel, displacing by the
other pipe a corresponding quantity of water which has become charged
with disinfectant. The measure of disinfecting liquid so displaced flows
into the water supply pipe and mixes with the water previously to its
discharge into the pan of the closet and serves to deodorise and disinfect
any gases or matter with which it may come into contact. The most
ready way, and that which I adopt, of supplying the requisite quantity
of water to the vessel or bottle containing the disinfectant is to connect
the inlet pipe of the bottle or vessel with the delivery pipe leading from
the water supply valve to the closet. So long as the water supply valve
is open there will be a certain amount of pressure in the delivery pipe;
water in consequence of this pressure passes by the connection already
described into the bottle or vessel containing the disinfectant, and the
quantity of water so passing and of disinfectant discharged at each
action into the closet I regulate by means of a small tap upon the con-
necting pipe, or by the size of the pipes employed. Disinfectants may
be supplied to urinals and other places in a similar manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Howard in the Great Seal Patent Office on
the 14th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HOWARD, of 4, Linden Grove, Nunhead Lane, in the County of Surrey, 1
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of April, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did for Herself, Her heirs and successors,
give and grant unto me, the said John Howard, Her special license
that I, the said John Howard, my executors, administrators, and
assigns, or such others as I, the said John Howard, my executors, admi-
nistrators, and assigns, should at any time agree with, and no others,

page_text: from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS
FOR SUPPLYING DISINFECTANTS FOR DISINFECTING WATERCLOSETS AND FOR OTHER
PURPOSES," upon the condition (amongst others) that I, the said John
Howard, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and scals, 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 John Howard, do hereby declare the
nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:—
This Invention has for its object improvements in apparatus for
supplying disinfectants for disinfecting waterclosets and for other
purposes. For this purpose I employ a bottle or vessel placed near the
supply pipe of the closet and supplied with disinfectant. I use a solid
disinfectant soluble in water or a highly concentrated fluid or paste;
a concentrated solution of chloride of zinc is suitable. The bottle or
vessel is closed with a stopper, and it has two pipes connected with it;
these pipes may conveniently be passed through the cork or stopper with
which the bottle or vessel is closed water-tight. At each action of the
closet a regulated quantity of water is injected by one pipe into the
bottle or vessel, displacing by the other pipe a corresponding quantity of
water which has become charged with disinfectant. I prefer that the
pipe by which the water enters the bottle or vessel should descend nearly
to the bottom of it, whilst that by which the disinfectant passes away
descends but a short distance through the cork or stopper. When
water enters the bottle or vessel the measure of disinfecting liquid so
displaced may be caused to pass into the pan of the closet together with
the water which is simultaneously discharged from the water supply
pipe and will serve to deodorise and disinfect any gases or matter with
which it may come into contact. The most ready way, and that which
I adopt, of supplying the requisite quantity of water to the vessel or
bottle containing the disinfectant is to connect the inlet pipe of the

page_text: bottle or vessel with the delivery pipe leading from the water supply
valve to the closet. So long as the water supply valve is open there will
be a certain amount of pressure in the delivery pipe, the water spreader
in the closet pan offering some resistance to the free escape of the
water. Water in consequence of this pressure passes by the connection
already described into the bottle or vessel containing the disinfectant ;
an equal quantity of water charged with disinfectant is expelled from
the bottle or vessel and led into the pan of the closet; the quantity of
water so passing and of disinfectant discharged at each action into the
closet I regulate by means of a small tap upon the connecting pipe, or
by the size of the pipes employed. I prefer to lead the outlet pipe from
the bottle or vessel into the pan at a point in the immediate neighbour-
hood of the entrance of the watter supply. Sometimes I pass a third
pipe through the cork or stopper of the bottle or vessel, and I form
a funnel mouth at the top of this pipe. This arrangement admits of
the concentrated solution of the disinfectant being poured in from time
to time as it may be required. Disinfectants may be supplied to urinals
and other places in a similar manner.
What I claim is the arrangement of apparatus for supplying disin-
fectants to waterclosets and other places, substantially as described.
In witness whereof, I, the said John Howard, have hereunto set
my hand and seal, this Ninth day of October, in the year of our
Lord One thousand eight hundred and seventy-five.
