Year: 1875

page_text: LETTERS PATENT to Michael Henry Brown, of New Cross, in the
County of Kent, for the Invention of "CERTAIN IMPROVEMENTS IN
WATERCLOSETS FOR DEODORIZING AND DISINFECTING THE SAME, APPLICABLE
ALSO FOR OTHER PLACES."
Sealed the 21st September 1875, and dated the 27th March 1875.
PROVISIONAL SPECIFICATION left by the said Michael Henry Brown
at the Office of the Commissioners of Patents, with his Petition,
on the 27th March 1875.
I, MICHAEL HENRY BROWN, of New Cross, in the County of Kent,
do hereby declare the nature of the said Invention for "CERTAIN IM-
PROVEMENTS IN WATERCLOSETS FOR DEODORIZING AND DISINFECTING THE SAME,
APPLICABLE ALSO FOR OTHER PLACES," to be as follows:-
-
This Invention consists in certain improvements connected with
waterclosets, whereby a given quantity of disinfecting or deodorizing
fluid is introduced in the trap or container, instead of in the pan of the
closet as heretofore.

page_text: The means by which I propose to attain the above object are as
follows: I cast outside the pan of a watercloset and on one side
thereof a reservoir or receptacle to contain the disinfecting fluid.
The said reservoir is connected with the container or valve box by
means of a pipe furnished with a double valve and valve chamber, which
I construct as follows:-At the bottom of the reservoir aforesaid I fix a
cylindrical valve chamber furnished with two seats for a double valve, and
of such capacity as to contain a quantity of disinfecting fluid sufficient
to disinfect the soil in the trap each time the pan is emptied into it.
The valves are united by a rod or spindle, which passes through the
reservoir containing the fluid, and which is worked up and down by a
lever actuated by the main lever of the closet with which it is con-
nected. The pipe which unites the valve chamber with the container
joins the said container at its lower part near the trap of the closet.
A watercloset constructed as above works as follows:-When the
handle of the closet is pulled up the double valve rod aforesaid is
depressed by means of the lever connected thereto, thereby opening the
top valve and closing the bottom one, by which operation the valve
chamber will fill itself with fluid. When the handle is released the rod
lever rises, thereby opening the bottom valve and closing the top one,
the fluid contained in the valve chamber will then flow into the trap
and mix with the water, ready to disinfect the soil as it leaves the
pan.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Michael Henry Brown in the Great Seal Patent
Office on the 27th September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MICHAEL
HENRY BROWN, of New Cross, in the County of Kent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of March, in the

page_text: 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 Michael Henry Brown, Her special
licence that I, the said Michael Henry Brown, my exccutors, adminis-
trators, and assigns, or such others as I, the said Michael Henry Brown,
my executors, administrators, and assigns, should at any time agree with,
and no others, 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 "CERTAIN IM-
PROVEMENTS IN WATERCLOSETS FOR DEODORIZING AND DISINFECTING THE SAME,
APPLICABLE ALSO FOR OTHER PLACES," upon the condition (amongst others)
that I, the said Michael Henry Brown, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, 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 Michael Henry Brown, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement, that is to say :-
This Invention consists in certain improvements connected with
waterclosets, whereby a given quantity of disinfecting or deodorizing
fluid is introduced in the trap or container, instead of in the pan of the
closet as heretofore.
The means by which I propose to attain the above object are as
follows: I cast outside the pan of a watercloset, and on one side thereof,
a reservoir or receptacle to contain the disinfecting fluid.
The said reservoir is connected with the container or valve box by
means of a pipe furnished with a double valve and valve chamber, which
I construct as follows:-At the bottom of the reservoir aforesaid I fix a
cylindrical valve chamber furnished with two seats for a double valve,
and of such capacity as to contain a quantity of disinfecting fluid,
sufficient to disinfect the soil in the trap each time the pan is emptied
into it. The valves are united by a rod or spindle, which passes through.

page_text: Figure 1 is a side view of a pan furnished with my disinfecting or
deodorizing apparatus, shown in section; Figure 2 is an end view of the
same.
A is the pan; B, the trap; C, the lever for working the same by
means of the handle D; E, the container of an ordinary watercloset.
On the side of the pan A, I cast or fix a reservoir F for the disinfecting
or deodorizing fluid, which is admitted by the screwed plug G. At the
bottom of the reservoir is a valve chamber H furnished with two valve
seats h, h¹, and valves J, J', fixed on a rod K. This rod and valve
receives an up-and-down motion from a lever L, having its fulcrum at 1,
counterbalanced by a weight M, and connected with the lever C by a

page_text: rod N. The valve chamber H communicates with the container E by
means of a pipe O.
The manner by which a given quantity of disinfecting fluid is intro-
duced into the container E by means of the above described apparatus is
as follows:-When the handle D of the closet is pulled up the double
valve rod K is depressed by means of the lever L, thereby opening the
top valve J and closing the bottom valve J', by which operation the
valve chamber H will fill itself with fluid. When the handle D is
released the lever L rises, thereby opening the bottom valve J' and
closing the top valve J, and the fluid contained in the valve chamber H
will flow into the container E by the pipe O and mix with the water,
ready to disinfect the soil as it leaves the pan.
When it is desired to apply the aforesaid reservoir with its appliances
to existing closets, urinals, or other places requiring to be disinfected, it
may be applied at the side thereof, and connected by means of the
pipe O.
Having now described and set forth the nature and object of my said
Invention for "Certain Improvements in Waterclosets for Deodorizing
and Disinfecting the same, Applicable also for other Places," I would
remark in conclusion that I hereby declare my Invention to consist in,
and I claim, the improved means of introducing a given quantity of
disinfecting or deodorizing fluid in the container or trap of waterclosets
or other places, substantially as described and represented.
In witness whereof, I, the said Michael Henry Brown, have here-
unto set my hand and seal, this Twenty-seventh day September,
in the year of our Lord One thousand eight hundred and seventy-
five.
MICHAEL HENRY BROWN. (L.S.)
