PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Supplying Liquids in Proportion
to each other.
I, THOMAS WILLIAM BLOXAM, of the Generating Station, The Causeway, Wands-
worth, in the County of Surrey, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to apparatus in which the flow of one liquid causes the
delivery of proportional quantities of another and it is applicable to the admixture
of anti-incrustation liquid to the feed water of boilers and to other purposes.
The apparatus consists of a tube supplied at one end and always filled with the
first liquid whilst the other end is connected to a pipe or vessel containing the
second liquid. At this end there is a valve seat for a valve loosely fitting the tube
and free to move in it its travel being limited by an adjustable stop to which it
always tends to return by its buoyancy or otherwise and there is also a cock (or
valve) periodically opened by a meter or other motor actuated by the flow of the
second liquid.
The action is as follows: -on the cock being opened the first liquid flows along
the tube and passing out at its end mixes with the second liquid. The flow
however carries the valve with it until it comes to its seat at the end of the tube
and stops the flow. When the cock again closes the valve returns to the adjust-
able stop and is ready for the next delivery.
Improvements in Apparatus for Supplying Liquids in Proportion
to each other.
I, THOMAS WILLIAM BLOXAM, of The Dover Electricity Supply Co., in the County
of Kent, Engineer, 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: —
This invention relates to apparatus generally in which the flow of one liquid
causes the delivery of proportional quantities of another & particularly in which
the flow of water into boilers causes the admixture of proportional quantities of
anti-incrustation fluid.
The apparatus combines with the advantages of an ordinary sight feed imper-
meator that of automatically maintaining a previously determined proportion
between the quantity of water fod into the boiler & of anti-incrustation fluid

page_text: In the annexed drawings this apparatus is shown, & consists of a controller and
a valve or cock.
Sheet 3, shows the controller.
Sheet 1, shows the valve in suction & elevation, also a section of the controller.
Sheet 2 shows the apparatus arranged so as to be actuated by the mechanism of
a water meter.
The controller consists of a glass tube 1) Fig. 5 suitably mounted with stuffing
boxes, which is always kept full of the anti-incrustation liquid, by being
connected at one end by the pipe L to a reservoir of this liquid, whilst the other
end is connected by the pipe A through the valve or cock E (Fig. 1,) to the tank
or pipe containing the water to be softened.
At this end of the glass tube there is a valve seat E (Fig. 5,) for a valve A
loosely fitting the tube & free to move in it-its travel being limited by a stop C-
adjustable by means of the rod K passing through the stuffing box the valve
always tends to return to this stop by it's own buoyancy or otherwise.
This valve consists of a light dise or cone B loosely attached to a float, both made
of materials least corrodible by the liquid in the tube-iron or glass for example.
There is also an air vessel it connected by the pipe S, & a cock T for allowing
of air from the tube when filling.
the escape
The pin X is used to hold the valve A off its seat E when flushing the pipes
for cleaning or otherwise & may be raised by means of the head Y.
Fig. 1 shows a valve E fixed to a spindle L, this valve is closed by the spring B-
the tension of which is adjustable by means of the screw C passing through the
cover D, & acting on the washer H.
RIDER.
Fig. 3 shows a section of Fig. 5 through the line aa VV are holes for
screws securing the stuffing box to the plate W Fig. 5.
The union nuts N are for convenience in disconnecting the apparatus from the
pipes P.
In Fig. 1, the valve chest A has a thread cut on it at K for attaching it to the
meter or other motor.
The action of the apparatus is as follows. The mechanism of the meter M Fig. 4
or of a feed pump is caused by a cam K or otherwise to periodically open the
valve B, allowing a portion of the liquid contained in the tank T to How by
gravity or pressure through the controller & through the pipe P into the vessel
or pipe containing in this case the water to be softened.
The flow of liquid through the controller carries the valve A Fig. 4 with it,
until it reaches it's seat E stopping the flox. When the valve B again closes,
the valve A returns to the adjustable stop C & is ready for the next delivery.
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:-
(1.) In apparatus in which the flow of one liquid causes the delivery of propor-
tional quantities of another. The combination of two valves or a valve & a cock-
namely the valve A of the controller Fig. 5 & the valve E Fig. 1, for which
any form of valve or cock may be substituted. in such a way that the action of
the second valve or cock actuates the first valve, the stroke of which is limited
by an adjustable stop, substantially as & in the manner described.
