SPECIFICATION in pursuance of the conditions- of the Letters Patent,
filed by the said Edward Gregson Banner in the Great Seal Patent
Office on the 13th February 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD 1
GREGSON BANNER, of No. 11, Billiter Square, in the City of London,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of August, in the year
of our Lord One thousand eight hundred and seventy-three, in the:
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Edward Gregson Banner,
Her special license that I, the said Edward Gregson Banner, my
executors, administrators, and assigns, or such others as I, the said
Edward Gregson Banner, 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 "IMPROVEMENTS IN DISINFECTING APPARATUS,”
upon the condition (amongst others), that I, the said Edward Gregson
Banner, 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 Edward Gregson Banner, do
hereby declare the nature of the said Invention, and in what manner

page_text: 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 disinfecting
apparatus.
In order to apply systematically a disinfecting liquid in connection
with the use of waterclosets, I fit in the closet a glass vase for containing
the disinfectant, and at the bottom of this vase is a valve opening into a
small pipe leading to the pan of the closet. The stem of the valve is
tubular, and serves as a vent to enable the pipe to discharge freely; a
connection (as for a bell) is made from the valve stem to the door of the
closet, so that each time the door is opened a portion of the disinfectant
is discharged into the pan.
The containing vase being of glass, any one entering the closet can
observe if the vase requires to be replenished.
In order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawings here-
unto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view; Figure 2, a vertical section; and Figure 3,
a plan partly in section of disinfecting apparatus arranged according to
my Invention. a, a, is a bracket fixed in any convenient position,
and 6 is a glass vase cemented into the foot b³, which may very suitably
be of cast lead. In this pot is a chamber &, closed at the top by a
cover c, and at the bottom the piece d, which may be cast in brass, fits
into and closes it. e is a brass tube passing freely through the parts o
and d; o³, o³, and d', d, are perforations in these parts; e' is an air hole
in the side of the tube e, which is open at the top; fis a leaden valve
fixed on the tube e, and covered with india-rubber discs ƒ¹ and ƒª at the
top and bottom; g is a chain attached to the tube e, and so connected
with the door of the closet that it is drawn up when the door is opened;
it passes over a pulley ¹ on a fixed-arm h; i is a pipe leading in any
convenient way into the pan of the closet.
Figure 4 show a lever for working the apparatus; it is fixed to the
door frame in such manner that the door when closed presses back its
head %, causing it to rock upon its fulcrum &, so that a wire or chain
passing from its other extremity m may give motion to the tube e and

page_text: valve f, with which it is connected through the chain g. The arm m of
the lever is of spring steel, so that no exact adjustments are necessary.
When the valve is in its lower position, closing the perforations d', d², the
chamber 6 fills with the disinfecting liquid, and when by closing the
door of the closet the valve is raised, closing the perforations o³, c¹, the 5
contents of the chamber 63 are discharged by the pipe i into the pan of
the closet, air entering the chamber 6 through the aperture e¹ in the
side of the tube e.
In place of working the apparatus from the door of the closet, it may
be worked from a hinged seat, or in other convenient way.
The disinfecting liquid which I prefer is chloralum, but other
disinfectants may be similarly applied.
What I claim is, arrangement of disinfecting apparatus, substan-
tially as described.

In witness whereof, I, the said Edward Gregson Banner, have 1
hereunto set my hand and seal, this Eleventh day of February,
in the year of our Lord One thousand eight hundred and seventy-
four.
