PROVISIONAL SPECIFICATION.
Improvements in Disinfecting Apparatus for use with Flushing
Cisterns.
PAUL ERNEST SWINSTEAD, 3 Grove Lane, Stamford Hill, London, N.
Teacher do hereby declare the nature of this invention to be as follows:-
A vessel to hold a soluble disinfectant. Near the top of one side, a small tube
passes through & reaches nearly to the bottom of the inside of the vessel. The top
of the vessel is continued upwards either bodily or by a narrow tube so that when
the whole is placed in a flushing cistern the upward continuation may rise above the
highest level of the water.
By means of the invention a small quantity of the solution of the disinfectant is
drawn from the bottom of the vessel where it is strongest & passes into the outside
cistern. The quantity so passing is regulated by the height of the top of the side
tube & is equal to the amount standing above that point.

COMPLETE SPECIFICATION.
Improvements in Disinfecting Apparatus for use with Flushing
Cisterns.
1, PAUL ERNEST SWINSTEAD, of 3 Grove Lane Stamford Hill London N.
Teacher do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement:
.
The invention consists of a special form of vessel to hold a soluble disinfectant.
A small tube passes through the top or side and extends for some distance down,
opening to the interior of the vessel at its lower end. The top of the vessel is
continued upwards either bodily or by a tube, so that when the whole is placed in a
flushing cistern the upward continuation may rise above the highest level of the
water, the top being open so that a fresh supply of disinfectant may be added
without removal.
By means of the invention a small quantity of the solution of the disinfectant is
drawn from near the bottom of the vessel where it is strongest and passes into the
outside cistern. The quantity so passing is regulated by the height of the top of
the small tube and is equal to the amount standing above that point inside the
vessel.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings, in which
Figs. 1 and 2 are vertical sections of one form of vessel placed in cistern, Fig. 1
showing the vessel when the cistern is full, and Fig. 2 when cistern is empty, and
Figs. 3 and 4 are sections of slightly modified forms of vessel.
A is the vessel, containing the disinfectant B at the bottom, which is filled in to
a suitable height, almost or completely up to the lower end of the tube C, which
projects downwardly, opening into the receptacle. According to Figs. 1 and 2 the
vessel is furnished with an extension or tube A', which extends to such a height
that the water in the cistern when it is full will not cover it. According to Fig. 3
the vessel itself extends to that height and is open at top, the tube C leading
through the side. The disinfectant can thus be dropped in through the open top of
the vessel or tube A' whenever a supply is required.

page_text: The arrangement shown in Fig. 4 is substantially the same as Fig. 3, but the
tube C is placed on the outside of the vessel, the opening through the side being at
the lower end. The vessel is shown bell mouthed in order to allow the disinfectant
to be inserted more easily. The tube A' may also conveniently be made in this
form. When the cistern is supplied with water, the latter enters the vessel through
the small tube C, and fills it as high as the water outside. As the water inside can
only communicate with that in the cistern by means of the tube C there is no
danger of the disinfectant becoming dissolved, excepting in the water in the vessel,
so that no matter how long the water remains in the cistern it will not become
overcharged. A definite amount of water containing disinfectant will be carried
away with the ordinary water at each dicharge, the amount being equal to that
contained in the extension A¹ in Fig. 1, and the quantity situated above the
aperture in the side of the vessel in Fig. 3 when the cistern is full. The water in
the cistern outside the vessel does not become perceptibly charged with disinfectant,
so that there is no danger of it escaping and attacking the valves, &c., as it is
completely carried away at each discharge.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
(1) A vessel for holding disinfectant for use with flushing cisterns, having an
open top and a downwardly extending tube through which the water passes,
starting below the level of the top and opening at its lower end into the vessel,
substantially as and for the purposes specified.
(2) A device for use in connection with flushing cisterns, consisting of a vessel A
carrying a quantity of disinfectant, having a small downwardly extending tube C
and an extension A', open at top, substantially as described and shown in Figs. 1
and 2 of the drawings and for the purposes specified.
(3) The improved device for use in connection with flushing cisterns, consisting
of a vessel A with open top carrying a soluble disinfectant, having a tube C, with
an aperture in the side at one end of the tube, substantially as described and shown
and for the purposes specified.
