PROVISIONAL SPECIFICATION.
A New or Improved Hydro-static Apparatus for Automatically
Mixing with Water, or other Liquid, Disinfectants, Softening or
Purifying Substances, or Saturated Solutions of any Soluble Sub-
stances in Definite Proportions.
I, FARADAY SPENCE, of 67 Grey Street, in the City and County of Newcastle
upon-Tyne, Stockbroker, do hereby declare the nature of this invention to be as
follows:-
My invention specially relates to a hydro-static apparatus for automatically
discharging any required quantity of disinfectant into a cistern or tank; applicable
also to other purposes such as the adding automatically any required quantity of a
saturated solution of dyes, chemicals, or other soluble or dissolved substances
contained in said apparatus to water, or other solvent or re-agent of such
substances, contained in a cistern or tank, for the purpose of softening or purifying
such water, or of forming a diluted solution of any desired strength, or generally
of affecting a body of liquid by the addition of other liquid automatically supplied
and regulated.
The
The object of my invention is to provide an apparatus for the aforesaid purposes
of simple construction and incapable of getting out of order, which can be cheaply
constructed of any cleanly and durable material, such as glass, earthenware, or any
suitable metal, acting automatically by hydrostatic pressure without the action of
a syphon. The apparatus which is a vessel of cylindrical or other convenient
form, and which contains in its lower portion the soluble disinfectant, dye, chemical
or other substances is simply placed on the floor of the cistern or tank.
apparatus should be greater in height than the depth of the liquid contained in
the cistern or tank when filled to its ordinary level, and will have formed with or
attached to it a vertical tubular channel, so that the lower end thereof shall open
inwards into the apparatus, and the upper end outwards into the cistern or tank at
a point which is regulated by, or determines the quantity of aforesaid solution
required to be supplied at each charge or discharge of the cistern or tank, and it
may have a loose lid to exclude dirt. The apparatus, charged with the disinfectant
ar other substances, is to be placed in the cistern or tank and to prevent it floating
it may either be filled with the liquid to be affected or simply held down till filled
therewith. The action is as follows:-
=1
The cistern or tank, being already filled, or being filled in the usual way with
water or other liquid till the level thereof is above the upper opening of the vertical
channel or tube aforesaid, the water or other liquid flows down it, dissolves the
disinfectant or other soluble substances, and rises in the apparatus until it reaches
the same level as that of the liquid in the cistern or tank. The downward current
in said vertical channel or tube promotes the solution or reduction of the soluble
substances by bringing the inflowing liquid from the cistern into close contact
therewith, and by next rising in the apparatus it tends by the action of specific
gravity and diffusion to thoroughly mix and make of uniform strength the solution
therein. The apparatus is then ready for action and, on the cistern or tank being
discharged the solution in the apparatus flows upwards through the vertical channel
or tube into the cistern or tank, until the level of such solution has fallen to, or
near to, the level of the upper opening. The upward flow not only draws off the
strongest part of the solution, if there be any difference in strength, but also tends
to remove any sediment or deposit and so maintain the apparatus in clean and
working order. When the cistern or tank is refilled the action proceeds as first

page_text: described, the incoming liquid flowing down the vertical- channel or tube until the
levels of liquids inside and outside the apparatus are alike and so on alternately
and automatically. The quantity of solution supplied at each discharge from the
apparatus is nearly equal to the volume contained therein, between the level of
the top of the vertical channel or tube and the highest level which the solution
reaches, and this volume may be regulated by altering the relation of the two
levels in any convenient manner, such as by raising the apparatus on packing
pieces, or by suspending it from a cross-piece, so that it may be raised or lowered,
or the vertical tube may be made to slide in a watertight joint so as to be raised or
lowered, or by any other similar means. Although I prefer to make the apparatus
separate from the cistern or tank, it may form part thereof, a compartment or
chamber being formed in its stead, and a vertical channel or tube equivalent to,
and acting in the same way as the aforesaid being fitted thereto.

A New or Improved Hydro-static Apparatus for Automatically
Mixing with Water, or other Liquid, Disinfectants, Softening or
Purifying Substances, or Saturated Solutions of any Soluble Sub-
stances in Definite Proportions.
I, FARADAY SPENCE, of 67 Grey Street, in the City and County of Newcastle-
upon-Tyne, Stockbroker. do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
My invention specially relates to a hydro-static apparatus for automatically
discharging any required quantity of disinfectant into a cistern or tank; applicable
also to other purposes such as the adding automatically any required quantity of a
saturated solution of dyes, chemicals, or other soluble or dissolved substances
contained in said apparatus to water, or other solvent or re-agent of such
substances, contained in a cistern or tank, for the purpose of softening or purifying
such water, or of forming a diluted solution of any desired strength, or generally
of affecting a body of liquid by the addition of other liquid automatically supplied
and regulated.
The object of my invention is to provide an apparatus for the aforesaid purposes
of simple construction and incapable of getting out of order, which can be cheaply
constructed of any cleanly and durable material, such as glass, earthenware, or any
suitable metal, acting automatically by hydro-static pressure without the action of
a syphon. The apparatus which is a vessel of cylindrical or other convenient
form, and which contains in its lower portion the soluble disinfectant, dye, chemical,
or other substances is simply placed on the floor of the cistern or tank. The
apparatus should be greater in height than the depth of the liquid contained in
the cistern or tank when filled to its ordinary level, and will have formed with or
attached to it a vertical tubular channel, so that the lower end thereof shall open
inwards into the apparatus, and the upper end outwards into the cisteru or tank at
a point which is regulated by, or determines the quantity of aforesaid solution
required to be supplied at each charge or discharge of the cistern or tank, and it
may have a louse lid to exclude dirt. The apparatus, charged with the disinfectant
or other substances, is to be placed in the cistern or tank and, to prevent it floating,
it may either be filled with the liquid to be affected or simply held down till filled
therewith, and when once filled it requires no further attention, except to recharge
with disinfectant &c. when required. The action is as follows:-
The cistern or tank either already filled, or being filled in the usual way, with

page_text: quantity of one liquid, of practically uniform strength, may be added to another
liquid for the purpose of affecting it as may be desired, substantially as hereinbefore
set forth and, in one form, illustrated.
