Improvements in Apparatus for Automatically Delivering Disinfectant
or other Compound to a Charge of Water.
I, JAMES LUVIAN WADE, of the Firm of J. L. Wade and Company, Limited,
Manufacturing Chemists, of 62, Nine Elms Lane, London, in the County of
London, do hereby declare the nature of this invention to be as follows:-
This invention for improvements in apparatus for automatically delivering
disinfectant or other compound to a charge of water relates more especially to
that class of disinfectors which contain a soluble solid disinfectant and which
each time a tank or cistern is filled and emptied delivers a small quantity of the
disinfectant to the water, and has for its object to provide a disinfector that,
when charged ready for use is applied by simply placing it inside the tank or
cistern in which it should be more or less completely immersed when the tank
or cistern is full. This disinfector can thus be easily removed for re-charging
or other purpose. The disinfector is applicable more particularly to flushing
cisterns, water-carts, and the like.
This invention consists in a vessel for containing the disinfectant, an air tube
outside the vessel and whose upper end communicates with and terminates near
the top of the vessel, and whose other or lower end terminates outside the vessel
and some distance below the upper end, one or more small disinfectant pipes
extending some distance inwards from the top of the vessel and a countersunk or
recessed top or shallow container round the upper orifice or orifices of the dis-
infectant pipes. The small pipes are perforated with small holes. The lower
orifice of the air tube may be adjustable. The vessel is provided with a large
opening closed by a screw cap to facilitate the re-charging of the apparatus.
It will readily be seen that the vessel can be made of any shape or size to suit
the tank or cistern to which it is applied, and that it can be used to automatically
deliver a softening solution to hard water.

I, JAMES LUVIAN WADE, of the Firm of J. L. Wade and Company, Limited,
Manufacturing Chemists, of 62, Nine Elms Lane, in the County of London, do

page_text: 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 follow-
ing statement:-
This invention for improvements in apparatus for automatically delivering
disinfectant or other compound to a charge of water, relates more especially to
that class of disinfector containing a solid disinfectant more or less soluble in
water, and which, each time a tank or cistern is filled, delivers a small quantity
of the dissolved disinfectant to the water in the tank or cistern; and has for
its object to provide a disinfector that when charged ready for use is applied
by simply placing it inside the tank or cistern in which it should be more or
less completely immersed when the tank or cistern is full. This disinfector
can thus also be easily removed for recharging or other purposes. The disinfector
is applicable more particularly to flushing cisterns, water carts, and the like,
and also, for automatically delivering a softening solution to water.
This invention consists in a reservoir for containing the solid disinfectant and
having a dished top, an air tube outside the reservoir and whose upper end
communicates with the top of the vessel, the lower end terminating above the
bottom of the reservoir, but external to it and a small water inlet and disin-
fectant emission tube extending downwards internally from the dished top of
the vessel.
The accompanying drawing is a sectional elevation of a disinfector constructed
according to this invention.
The reservoir a is provided externally with an air orn-shaped pipe having
its shorter leg b connected to the top of the vessel a. The longer legh of the
air or pipe extends downwards outside the reservoir to nearly the bottom.
The top of the reservoir a is dished and a small pipe i extends downwards from
the dished top and from a distance of about one inch from the top it is per-
forated with holes o to the bottom.
The disinfectant is inserted into the reservoir a through the nut e. The whole
apparatus is then placed in the flushing cistern and fills with water which
becomes saturated with the disinfectant.
During the flushing operation, as the flushing cistern empties, the water con-
tained in the lower part of the leg falls and thus sucks water into the
reservoir a through the pipe 2. When the water in the cistern falls to the
level of the top of the reservoir a the dished top will be full of water and this
water will also pass into the reservoir through the pipe i. As the cistern is
again filled the water rises up the leg and forces out through the small tube i
all the water that was drawn in at the previous flushing operation into the
flushing cistern and as this water is saturated with the disinfectant the charge
of flushing water is rendered disinfectant for the next flushing operation.
The tube may be completely immersed or it may extend out of the water
of the cistern.
h
The longer leg may be made adjustable so that the quantity of disinfectant
delivered to the charge of water can be varied. It will readily be seen that the
reservoir a can be made of any shape to suit the tank or cistern to which
it is applied.
The dished top of the reservoir must be below the level of the water in the
flushing cistern when full; and the lower end of the tube i or its uppermost orifice
if perforated must be below the termination of the lower end of the leg b.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
A disinfector consisting of a disinfectant reservoir having a dished top, a
small water inlet and disinfectant emission tube extending downwards from the
dished top into the reservoir, an air tube having its upper end connected to the

page_text: reservoir and terminating above the uppermost perforation of the inlet and
emission tube and having its lower end terminating external to the reservoir
a short distance from the bottom.
