AN IMPROVED DISINFECTING
Year: 1874

page_text: LETTERS PATENT to Michael Henry Brown, of New Cross, in the
County of Kent, and Matthias George White, of Landport, in the
County of Hants, for the Invention of "AN IMPROVED DISINFECTING
PROVISIONAL SPECIFICATION left by the said Michael Henry Brown
and Matthias George White at the Office of the Commissioners of
Patents, with their Petition, on the 26th March 1874..
We, MICHAEL HENRY BROWN, of New Cross, in the County of Kent,
and MATTHIAS GEORGE WHITE, of Landport, in the County of Hants,
do hereby declare the nature of the said Invention for "AN IMPROVED
DISINFECTING AND. DEODORIZING APPARATUS FOR WATERCLOSETS AND OTHER
PURPOSES," to be as follows:-
This Invention consists in constructing an apparatus by means of
which a given quantity of disinfecting fluid may be made to flow into
the pan of a watercloset or other place.
'

page_text: The following is an example of our said Invention as applied to water-
closets: We fix a small cistern containing the disinfecting fluid against
the wall over the seat of a watercloset. Through the bottom of this
cistern we pass a tube, one extremity of which goos into the pan of the
closet, and the other end terminates by a funnel, the opening of which
projects over the level of the fluid in the cistern. We next place over
the fluid a spindle, which passes loosely through the sides of the cistern,
and on to this spindle is fixed (inside the said cistern) a tube, at one
end of which is attached a small bowl. Outside the cistern and on the
aforesaid spindle is fixed a lever, one end of which is weighted, and the
other connected with the lever that works the plug for flushing the pan.
When the apparatus is at a standstill the bowl aforesaid remains above
the level of the fluid in the cistern by means of the weighted lever, and
when the plug is pulled up this lever is brought down, bringing with it
the bowl to be charged with the disinfecting fluid, and on releasing the 1
plug discharges itself into the funnel, and conveys the disinfecting fluid
by the pipe aforesaid to the pan either direct or through the service pipe
of the watercloset, and mixes it with the trapping water.
Another mode of bringing up a given quantity of fluid to the funnel
aforesaid consists in replacing the tube and bowl on the spindle by a
disc, on the periphery of which are fixed a scries of small bowls or
scoops. When the plug is pulled up it is caused to act by means of a
wire on a lever, at one end of which is attached a rod furnished with a
pawl, which takes into a ratchet wheel having the same number of teeth
as there are scoops on the disc. Stop pins are also attached to the said
disc in such a manner that when they come in contact with the rod
aforesaid the disc will be prevented from moving more than one scoop at
a time; thus only one will empty itself in the funnel every time the
plug is pulled up.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 30
filed by the said Michael Henry Brown and Matthias George White
in the Great Seal Patent Office on the 26th September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MICHAEL
HENRY BROWN, of New Cross, in the County of Kent, and MATTHIAS
GEORGE WHITE, of Landport, in the County of Hants, send greeting. 35

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of March, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Michael Henry Brown and Matthias George
White, Her special licence that we, the said Michael Henry Brown and
Matthias George White, our executors, administrators, and assigns, or
such others as we, the said Michael Henry Brown and Matthias George
White, our 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
"AN IMPROVED DISINFECTING AND DEODORIZING APPARATUS FOR WATERCLOSETS
AND OTHER PURPOSES," upon the condition (amongst others) that we, the
said Michael Henry Brown and Matthias George White, our executors
or administrators, by an instrument in writing under our, 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 we, the said Michael Henry Brown and
Matthias George White, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following state-
ment, that is to say :-
This Invention consists in constructing an apparatus, by means of
which a given quantity of disinfecting fluid may be made to flow into
the pan of a watercloset or other place.
The following is an example of our said Invention as applied to water-
closets: We fix a small cistern containing the disinfecting fluid against
the wall over the scat of a watercloset. Through the bottom of this
cistern we pass a tube, one extremity of which goes into the pan of the
closet, and the other end terminates by a funnel, the opening of which
projects over the level of the fluid in the cistern. We next place over
the fluid a spindle, which passes loosely through the sides of the cistern,

page_text: of the fluid should never be higher than the top of the funnel F; G is a
lever furnished at g with a weight; this lever is connected with the
lever that works the plug for flushing the pan by means of a wire H.
When the plug is pulled up the lever G is pulled down and assumes the
position G', the tube D and bowl E taking the position D', E'. When
the plug is released the lever G, tube D, and bowl E will be brought
into their original positions by the action of the weight g, and the liquid
contained in E will flow into the funnel F' and tube. F', which will
convey it into the pan, where it will be mixed with the flushing water.
Figure 3 is a sectional elevation; and Figure 4 a plan of another
mode of bringing a given quantity of disinfecting fluid into the pan of a
watercloset. A is the cistern containing the fluid; B, a shaft on which
is fixed a bent rod or wire C furnished at one end with a bowl D.
Motion is given to the shaft B by means of a cog wheel E and quadrant F.
This quadrant is fixed on the fulcrum of a weighted lever G connected
with the lever under the seat of the watercloset. H is a receiver con-
nected by a pipe with the pan of the closet. When at rest the bowl D
is always out of the fluid, and is kept in this position by means of the
weight g, but when the lever under the seat is depressed the bowl will
assume the position D¹ shown in dotted lines. When the lever of the
closet rises again the bowl will take its original position, emptying itself
in the receiver H, which will convey the contents thereof into the pan.
Figure 5 is an elevation, and Figure 6 a plan of a third mode of
conveying disinfecting fluid to the pan of a watercloset. A is the
cistern; B, the lid; C, a spindle on which is fixed a disc D, around
which are attached small bowls d. These bowls empty themselves into
the funnel F, from which they are conveyed to the pan by the pipe F¹.
A rotary motion is given to the disc D by means of a ratchet wheel G
and ratchet H. This ratchet receives an up-and-down motion from the
weighted lever K, connected with the lever of the closet by means of
the wire K. Each time this lever is depressed and brought up again
the ratchet H will move the ratchet wheel G one tooth, thereby causing
one of the bowls d to empty itself in the funnel F.
In order that no more than one bowl shall be emptied at a time a

page_text: Having now described the nature and object of our said Invention for
"An Improved Disinfecting and Deodorizing Apparatus for Water-
closets and other Purposes," we would remark in conclusion that what
we claim as our Invention and desire to secure by the hercin-before in
part recited Letters Patent is, constructing disinfecting and deodorizing
apparatus substantially as described and represented.
In witness whereof, I, the said Michael Henry Brown, one of the
parties hereto, have hereunto set my hand and scal, this Twenty-
fifth day of September, in the year of our Lord One thousand
eight hundred and seventy-four.
MICHAEL HENRY BROWN. (L.S.)
