I STRETHILL HARRY WRIGHT, of 494 Talbot Street, Southport, in the County
of Lancaster, Doctor of Medicine, do hereby declare the nature of my said Inven-
tion for AN IMPROVED METHOD OF RAISING WATER AND OTHER LIQUIDS AND
APPARATUS EMPLOYED THEREIN, to be as follows:-
My Invention consists of an improved method of raising water and other
liquids and of a novel construction of syphon apparatus for carrying out such
method.
The method according to my Invention, consists in the employment of a portion
of water raised by the long leg of a syphon to run to waste, by which waste a body
of water is caused to rise in the short leg. To effect this, I employ a syphon
apparatus having a closed cistern, or chainber at its upper portion, in which the
body of water raised by the portion of water running to waste in the long leg is
received, which when full automatically, or otherwise empties itself, or is emptied.
The filling of the cistern is then resumed. Therefore the method and essential
feature of my Invention is--that a body of water running through the long leg of
a syphon, either full, or part full, exerts a power to act as an exhaust to a closed
chamber above the "bend" of the syphon and causes water to rise through the
short leg of the syphon into the chamber so exhausted above the "bend" namely
the point at which the water, or any portion of the water rising through the short
leg of the syphon begins to descend.
For example an apparatus according to my Invention and for carrying my
improved method of raising water, or other liquids into practice, consists of a closed
air-tight cistern provided with an ascending pipe from the water source opening
into the cistern through the bottom thereof and provided with a non return valve
and forming the short leg of the syphon, and a descending pipe opening into the
cistern near the top thereof and descending through the bottom of the cistern and
forming the long leg of the syphon. Between these pipes there is a communicating
pipe, or the descending pipe has a small orifice opening out into the cistern. This
communicating pipe, or orifice may bear a variable proportion to the area of the

page_text: pipe. The cistern is provided with an air inlet valve worked by a float, or other
mechanical contrivance.and a draw off pipe also provided with suitable valvular
apparatus.
In operation supposing the air to have been exhausted from the cistern, which
can be done by passing water down the descending pipe, water will flow up the
ascending pipe and fill the cistern and can be drawn off through the draw off pipe
at the bottom of the cistern. The air valve in the cistern admitting air to allow
of the water being drawn off. The non return valve on the top of the ascending
pipe, or short leg of the syphon preventing the water from escaping from such pipe.
As the cistern is emptied by the draw off pipe, the air valve is closed by a float
provided for that purpose and the portion of water escaping down the long leg of
the syphon draws, or ejects the air from the cistern and the water again flows into
the cistern through the short leg of the syphon and again fills the cistern, the air
valve being opened by the float when the cistern is filled. The water can be drawn
off through the draw off pipe as before. The operation is again repeated and the
apparatus constitutes an automatic pump.

I STRETHILL HARRY WRIGHT of 49* Talbot Street Southport in the County of
Lancaster Doctor of Medicine do hereby declare the nature of my Invention for
"AN IMPROVED METHOD OF RAISING WATER AND OTHER LIQUIDS AND APPARATUS
EMPLOYED THEREIN and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention consists of an improved method of raising water and other
liquids and of a novel construction of syphon apparatus for carrying out such
method.
The method according to my invention consists in the employment of a portion
of the water raised by the long leg of a syphon to run to waste by which waste a
body of water is caused to rise in the short leg. To effect this I employ a syphon
apparatus having a closed cistern or chamber at its upper portion in which the
body of water raised by the portion of water running to waste in the long leg is
received which when full automatically or otherwise empties itself or is emptied.
The filling of the cistern is then resumed. Therefore the method and essential
feature of my Invention is that a body of water running through the long leg of a
syphon and charging it part full of water exerts a power to act as an exhaust to
a closed chamber above the "bend" of the syphon and causes water to rise through
the short leg of the syphon into the chamber so exhausted above the "bend"
namely the point at which the water or any portion of the water rising through
the short leg of the syphon begins to descend the long leg or draw pipe through au
orifice in that pipe as hereafter described.
い
For example an apparatus according to my invention and for carrying my
improved method of raising water or other liquids into practice consists of a closed
air tight cistern or chamber provided with an ascending pipe from the water source
opening into the said chamber through the bottom thereof and provided with a
non-return valve and forming the short leg of a syphon and a descending pipe
opening into the chamber near the top thereof and descending through the bottom
of the cistern and forming the long leg of the syphon. This long leg or draw pipe
communicates with the chamber not only at its upper extremity but also by a small
orifice opening from the side of the portion of the said draw pipe within the
chamber or by a branch pipe having its ends opening respectively into the bottom
of the chamber and the side of the portion of the aforesaid pipe which is without
the chamber. The plane sectional area of this orifice or of this branch pipe is of
smaller calibre and bears a variable ratio to that of the aforesaid descending or
draw pipe The chamber is provided with an air inlet valve worked by a float
or other mechanical contrivance and a draw off, or discharge pipe also provided
with suitable valvular apparatus.
In operation supposing the air to have been exhausted from the closed chamber
which can be done by passing water down the descending or draw pipe water will
flow up the ascending or supply pipe and fill the closed chamber and can be drawn
off through the discharge pipe of the chamber. The air valve in the chamber
admitting air to allow of the water being drawn off The non return valve on the
top of the ascending pipe or short leg of the syphon preventing the water from

respect of the syphon.
Figure 5 is

Figure 6 is a sectional elevation on a larger scale of part of Figure 5.
My invention as before stated consists of an improved method of raising water
and other liquids and of a novel construction of syphon apparatus for carrying out
such method, the said method consisting in allowing a portion of the water which has
been raised by the action of the syphon to run to waste down the long leg of the
syphon and thus to act as a motor to exhaust a closed chamber above the "bend"
of the syphon and so cause a body of water to rise in the short leg and into the
closed chamber as hereinafter described. In my provisional specification I stated
substantially that I used a body of water running through the long leg of a syphon
either full or part full which exerted a power to act as an exhaust to a closed
chamber. I have found that the practical utility of the full bore, That is where
the long leg or draw pipe is allowed to flow with a charge of water not artificially
diminished, lies within very narrow limits and I therefore confine myself in the
description of my invention to the use of a part bore flow through the descending
pipe or long leg, That is where the charge is artificially diminished by mechani-
cally restricting the size of the orifice in the long leg or draw pipe I also prefer
to use in the employment of the part bore flow, pipes of small calibre as hereinafter
described. The essential feature of my invention being that a body of water
running through the long leg of a syphon and charging it part full of water exerts
a power to act as an air exhaust to a closed chamber above the "bend" of the
syphon and causes water to rise through the short leg of the syphon into the
chamber so exhausted above the "bend," namely the point at which water or any
portion of the water rising through the short leg of the syphon begins to descend
the long leg in the manner hereafter described The closed chamber when filled
being arranged to empty itself automatically or otherwise.
It is known that a pipe conveying water will carry with the current of water in
it a certain portion of air and by my invention.I have defined certain conditions

page_text: under which this effect may be utilized with great advantage such pipe being used
as the long leg of a syphon and of small sectional area and so exhausting a chamber
above the "bend" of the syphon as to cause water to flow into the said chamber
through the short leg of the syphon which must be of larger sectional area than
the long leg of the syphon. I prefer that its sectional area should be twice that of
the long leg or draw pipe. My invention provides an exhaust machine for raising
water, of great power of very rapid action and of wide spread applicability.
According to my invention the practical efficiency of water conveying pipes as
an exhausting apparatus depends
1. Upon the perpendicular or part perpendicular length of the waste or motor
water-conveying tubes below the level from which water is drawn by the short leg
of the syphon and this measurement I name for purposes of description the motive
height of the apparatus.
2. Upon the size of the pipes or tubes used. For any height small tubes with a
certain proportional charge of water exhaust more perfectly and economically than
large tubes small tubes also for any given motive height with a given quantity of
water used as a motor exhaust more rapidly than large tubes that is suppose the
motive height be 10 feet a gallon of water passed through inch tubes will produce
a more rapid exhaust than if passed through inch tubes of equal aggregate
sectional area to the aggregate sectional area of the inch tubes.
3. Upon the part bore flow of water through such tubes.
As an example of the method of raising water according to my invention and in
reference to Figure 1 of the Drawings a represents a closed chamber b the supply
pipe or short leg of the syphon rising from the water level c to and opening into
the closed chamber a at any level or height of the Chamber a and fitted with a
non-return valve b¹. d is the long leg of the syphon which I also herein treat of
as the draw pipe and which is carried up in the closed chamber a to near the top
thereof The pipe d is one half the diameter of the pipe b and at the point e there
is provided an orifice or port in the pipe d having a sectional area of smaller calibre
than the pipe d so as only to allow a part bore charge to flow down the pipe d
from the closed chamber a At the top of the closed chamber a and entering flush
thereinto there is a pipe f provided with a cock g. This pipe f is for the purpose
of letting air into the closed chamber a when required.
The action of the apparatus depends upon the perpendicular length of the draw
pipe d. The perpendicular length of the draw pipe d must be taken from the point
at which the water enters such pipe. That is from the "bend" of the syphon aș
defined in this Specification to the point of exit whilst the perpendicular height of
the short leg or supply pipe 6 must be taken from the supply water level c and a
maximum water level in the closed chamber a That is the efficiency of the
apparatus is increased by the increase of the length of the draw pipe d below the
supply water level c. This means that as the chamber a fills the water will rise
more rapidly as the length of the draw pipe below the water supply level c is
increased. For example if the perpendicular measurement from the water supply
level c to the orifice e in the draw pipe d be twenty four feet and the distance
from the water supply level c to the lower end of the draw pipe d be thirty feet,
water will rise about eight feet in the closed chamber a but it will rise with
great rapidity and the quantity of water which flows through the orifice e down
the draw pipe d and which is the motor will be much less than if the measure-
ment from the water supply level c to the bottom end of the draw pipe d were only
say ten feet.
The action of my Invention with reference to the diagram shown at Figure 1.-is
as follows:-Presume the chamber a to be filled or partly but sufficiently filled with
water a portion of this water escapes through the orifice e and down the draw pipe d
part bore drawing the air from the closed chamber a with it By this means a partial
exhaustion of the chamber a is obtained and the water rises from the supply water
level c through the pipe b into the closed chamber a by reason of such exhaustion.
A certain proportion of such water when raised is utilized as before described

page_text: by going to waste down the draw pipe d and acting as the motor to exhaust the
remaining space in the chamber a. As the chamber a fills with water or when the
chamber is filled with water such water can be drawn off from the chamber a by
any suitable "ventilating" valve, tap, cock, or like appliance.
g
As the water rises through the pipe b into the chamber a the supply being
greater than the waste or motor the water rises above the orifice e until the top h
of the pipe d is reached when the water level will remain stationary a little above
the point h and the water will flow full bore down the pipe d. If now the air
tap g on the pipe f be opened air will rush into the chamber a and the water level
will fall but if this tap ġ be closed a little before water has sunk to the level of the
orifice e and so as to leave sufficient water in the chamber a that the water level
will be maintained well above the orifice e and that there will be no danger of
the syphon b, e d being stopped in its action; this water by running to waste will
exhaust the air from the chamber □ the syphon will act and the water will rise in
the chamber a. A part of the water rising into the chamber always going as
motor down the pipe d so that a syphon the long leg of which goes part bore will
raise water into a closed chamber above the point at which water after ascending
the short leg, commences to descend the long leg. By alternately opening and
closing the air supply through the pipe fa pumping action is obtained in the closed
Chamber a the motor of which is the water flowing part bore down the long leg d
of the syphon.
If the closed chamber a be lengthened as shown at Figure 2 and the same fittings
be used as in Figure 1 the same action will be repcated water will rise in the closed
chamber a above the point e to a height nearly equal to the perpendicular measure-
ment from the water supply level c to the lower, or discharge extremity of the draw
pipe d.
"
This holds good with but little variation whatever the height of the "bend" of
the syphon bed provided the perpendicular height from the water supply level c
to the top of the closed chamber a be less than the height of the "water barometer'
for the time being that is to say: if the height of the "bend" of the syphon be d
equal twenty four feet and the vertical measurement from the water supply level c
to the discharge end of the pipe d equal eight feet the syphon bed will draw
water from six to seven feet above the top of the "bend" of the syphon be d.
The action of an apparatus according to my Invention for raising water is
syphonic that is the water used in this action as the motor rises from a water level
supply through a pipe or pipes corresponding to the short leg of the syphon passes
over the "bend" and descends a pipe or pipes corresponding to the long leg of
the syphon and leaves the apparatus at a discharge point below the level of supply
In its descent of the long leg this motor water raises water above the "bend"
described the parts of the machine being proportioned as herein described.
I have given certain distinguishing names to the parts of the apparatus according
to my Invention and when I attach a special meaning to any of these names
define that meaning.
(1) The short leg of the syphon apparatus I call "The Supply."
"
as
(2) The crown of the syphon is expanded into a receptacle of variable size which
can be opened or shut to the atmosphere This I call "The Chamber."
(3) "The Bend " I define as the point in this "Chamber" at which any portion
of the water in the "Chamber" having been placed therein or having risen therein
through "the supply" during the action of the apparatus begins to descend the
long leg or “draw pipe" or "pipes" by an orifice made in that pipe or by a pipe
entered therein within or close beneath the bottom of the "Chamber."
(4) The pipe or pipes of the apparatus which correspond to the long leg of a
syphon I name "the draw pipe or pipes."
" draws
(5) The vertical measurement from the level from which "The Supply
to the end of the "Draw Pipe or Pipes" I name "The motive height" and this
.height must be not less than about one third the height of "the Supply."

page_text: "
The Supply may be of any height under the height of the "Water Barometer
for the time being and this measurement must include the height of the "Chamber."
"The Supply" which I always measure from above the water level may be of any
sectional area greater than twice that of the "Draw pipe or pipes."
The "Chamber may be placed at any height as I have said provided its upper
level be below the height of the "Water Barometer" for the time being but for
practical purposes I advise a height of not greater than twenty seven feet from
the level of the water supply.
"
"The Bend" should be kept as low in the Chamber" as possible It must
always be so placed and guarded that the Water level in the "chamber" can never
sink under any conditions to it.
"
The pipe or pipes named "Draw pipes" in a machine working at small "motive
height" must be of small calibre. I prefer inch pipes and these pipes must be
charged part bore that is the water supply to them at "The Bend must be
diminished below the volume of water that such pipes would take if the orifice e
were not less in sectional area than the sectional area of the pipes. For practical
working I recommend a charge of to their full capacity. If a charge of 1th be
used the machine will work to economical issue and this charge should be used
when water is scarce and speed is not the desideratum-If a half bore charge be
used rapidity of action will be gained at the cost of economy of the motor water.
"
The exhaust power of water conveying tubes depends not only upon the quantity
of water supplied to them but also on the proportion existing between their sectional
area and length That is a small pipe say inch pipe with bore charge will for a
Motive height" of say 10 feet, give a better exhaust than or.1 inch diameter
pipe with the same proportional charge of water. When the "Motive height" is
very high pipes of greater diameter have the advantage of being less liable to
foul.
ני
By increasing the "Motive height" ie by lengthening the "draw pipe or pipes
speed and economy are gained, that is with any part charge a greater "motive
height" will increase the speed of the machine and economise its motor.
If it be desired to increase the power of the apparatus with any given "Motive
height" that is done by multiplying the number of "draw pipes" The power of
the apparatus may thus be increased in the direct ratio of the multiplication of the
draw pipes" provided the "supply" be increased in the ratio to the "draw pipes"
already given either by increasing the diameter of one supply pipe or by multi-
plying the number of pipes in the supply and the water level be maintained.
"
In conclusion of this explanatory portion I give an instance of the use of this
syphon apparatus in utilizing and increasing the head power of a small fall with
this object. I now refer to the diagram Figure 3 of the Drawings which represents
a natural water fall the upper level of which is at c.
The fall of water froin c
to c equals 10 feet. The apparatus according to my Invention namely the
"Chamber" a supply b and draw pipe d is placed in reference to the water fall c
and c¹ as shewn in the diagram. The height of the supply 6 is 10 feet from the
level c to the top of the "chamber" a. The "draw pipe "d thus gives a "motive
head" of 10 feet which equals the distance or height of the water fall from c to c¹.
This arrangement of apparatus with a rapidity regulated by the number and size
of "draw pipes" used and with considerable economy fills the "Chamber
water that is approximately for every two and a half gallons of water which are
raised into the "chamber" a one gallon will be retained in the "chamber" Ct.
Therefore if the one and a half gallons which flow through the "draw pipe" d
be held the notor of the apparatus using quantity of motor water as the basis of
a calculation, this apparatus will do a service of above sixty to sixty five per cent.
The "Chamber" a will discharge its water through the discharge pipe n either at c
with an initial head of ten feet returning its water to the source of supply or it
will discharge it through the pipe n at c¹ with a head of twenty feet.
a with
In Figure 4 there is illustrated an apparatus embracing the features above set
forth and the action of which is not automatic except in respect to the syphon..

page_text: In this apparatus I provide the closed "chamber" a with a diaphragm i which
is placed sufficiently above the bottom of the vessel forming the "chamber" a to
partition off a portion a¹ of the vessel a considerably exceeding the aggregate cubic
capacity of the entire length of the supply pipe b, by "sufficiently above" I mean
that a sub-diaphragmatic part of the "chamber" a must be partitioned off the
contents of which discharging through the piped in the manner described will
raise water from c to the brim of the pipe 6 the exact capacity of this portion must
be in each case ascertained The supply pipe b rises from the water level c through
the bottom of the chamber a and terminates a short distance below the diaphragm i
which diaphragın i. has an orifice j provided with the valve k of the non-return
type opening upwards and forming a communication between the lower or sub-
diaphragmatic portion a¹ of the "chamber" and the upper or super-diaphragmatic
portion of the "chamber" a The sectional area of the orifice j being equal to or
exceeding the sectional area of the supply pipe b The supply pipe b is so positioned
not immediately below the orifice as to allow of its free discharge beneath the
diaphragm and into the sub diaphragmatic portion a¹ of the "chamber "a The
portion a when the valve k is open forms part of the "chamber" a and when
the valve is closed is shut off from the super diaphragmatic portion of the
"chamber" a. The sub diaphragmatic portion a¹ always remaining open to the
supply pipe b and to the orifice e of the draw pipe d hereafter described. dis
the draw pipe and consists of a pipe which may be arranged as shewn in the
Drawings or in other convenient manner. The upper end of the said pipe d
being provided with a two way cock g and a through way air pipe f. One end of
the pipe entering the vessel a and the other end of the pipe f being open to the
atmosphere, the cock g being common to the pipe f and the pipe d and serving as
a device whereby the interior of the "chamber" a is open to the atmosphere through
the pipe and closed to the draw pipe d, or is closed to the atmosphere by the
cock g and is in communication with the draw pipe d for exhausting purposes.
Below the "chamber" a the pipe d is provided with a small branch pipe c. having
a cock e¹ and communicating between the draw pipe d and the sub-diaphragmatic
portion of the "chamber" a and having the same function as the orifice e of the
draw pipe d before spoken of in reference to Figures 1 and 2.-The cock e¹ con-
trolling the orifice of the pipe e so as to give such orifice a variable proportion to
the sectional area of the draw pipe d. The draw piped is provided with a shut off
cock d and with a pipe having a cock which pipe communicates with an
extraneous water supply vessel m for starting the action of the apparatus as here-
after described The "chamber" is supplied above the diaphragm i with a
discharge cock and pipe n The sub diaphragmatic portion a¹ of the "chamber" a
is provided with a pipe and cock o through which the sub-diaphragmatic portion
of the "chamber" a may be primarily filled with water.
l
The operation of the apparatus is as follows:-(it being understood that the
supply pipe b the draw pipe d and the orifice pipe e are proportioned as respects
sectional area and length, as herein before set forth) The cock g is closed so as to
open communication between the interior of the "chamber" a and the draw pipe d
through the pipe f. The cock is also closed; the cock e¹ is opened, it being
understood that the subdiaphragmatic portion a¹ of the "chamber" a has been
filled with water through the pipe and cock o up to the brim of the pipe b and that
the cock o has then been closed This water from a¹ passes through the pipe e part
bore down the draw pipe d (the cock being open) and by its passage exhausts the
air from the "chamber" & through the pipes f and d-This exhaustion of the air
from the "chamber" a causes water to rise from the water supply level c through
the supply pipe b into the sub diaphragmatic portion a¹ of the "chamber"
when such portion a¹ is filled the water will rise through the valve and fill the
super diaphragmatic portion of the "chamber
a.
a and
Instead of starting the apparatus by charging it with water through the pipe o
the water used to start the apparatus may be supplied from the extraneous vessel m
through the pipe to the draw pipe d and the water being allowed to pass part bore

page_text: "
down the draw pipe d from the pipe l will exhaust the "chamber" a through the
pipes and d and cause the water to rise through the supply pipe b and fill the
"chamber" a. The extraneous vessel m if the water supply be limited must be
regulated as to its capacity in the same manner as the portion a¹ of the chamber a.
As soon as the water flows into the portion a¹ of the "chamber a from the
supply pipe b and begins to descend the draw pipe & through the orifice pipe e
the syphon bed is in action and all extraneous water supply as from o.and is
shut off. After filling the "chamber" a the water will continue to rise until it
passes through the pipe f and down the pipe d but if when the water has risen
to any required level in the "chamber" a and above the discharge pipe n, the
cock g be turned so as to open the pipe f to the atmosphere and close it to
the draw pipe d and the cock n be opened; the contents of the super diaphragmatic
portion of the "chamber" a will be discharged through the cock n and the valve k
will shut back closing communication between the super diaphragmatic portion and
the sub diaphragmatic portion of the chamber a but the syphon action of the
pipes bed will continue. Upon closing the cock n and reversing the cock g so as
to again place the pipe f and the interior of the " chamber" a in communication
with the draw pipe d and to close the pipe f to the atmosphere exhaustion of the
"chamber" a will recommence and the water will again rise and fill the "chamber" a
without the use of extraneous aid.
In Figure 5 there is shown an apparatus according to my invention in which the
emptying of the "chamber" a after filling and the action of refilling is automatic
In every respect except in the use and action of its automatic mechanism for emptying
and reclosing the "chamber" a this apparatus is the same as that described in
reference to Figure 3.
The particular automatic mechanism shown in Figures 5 and 6 of the drawings
of this Specification and herein referred to forms the subject matter of a subsequent
application by me for Letters Patent which application is numbered 1148' and
dated 26 January 1886 and is a very suitable mechanism to use with the apparatus
herein described to make the operation thereof automatic and has been invented by
me since the date of this present application but I would have it understood that
although I have shown this particular automatic mechanism and prefer to use it,
any other suitable arrangement of automatic appliance may be used.

I will now describe this automatic mechanism which consists of two valves of
the piston type one the valve g being in communication with the interior of the
chamber a through the port f and with the outside atmosphere through the pipe f,
the other the valve d² being in communication with the interior of the "chamber" a
through the port d³ and also being in communication with the draw pipe d. The
ports in the valves y and d must be so situated that the port of the valve dis
raised within the enclosing cylinder just before the port of the valve g leaves the
enclosing cylinder of that valve. These valves g and d² are carried by a bracket p
and contained within a dome on the top of the "Chamber The pistons of the
valves g and d² are connected by a lever q in such a manner that when the valve g
is opened and communication is open from the atmosphere through the valve g to
the "chamber a the valve is shut and there is no communication between the
"chamber" a and the pipe d through the valve and in like manner when the
valve d² is open the communication through the valve g is closed. The valves
and d² are worked by a float r which has a lifting motion and initiates the closing
of the valve d² and opening of the valve g and by a cup or weight 8 which has a
falling motion and draws down the float rand opens the valve d and closes the
valve g. The cup weights is provided with a float 8 such as will almost but not
quite sustain the weight of the cup weights until the water level in the "chamber" a
falls from it and the apparatus r and s with their connections must be such that their
combined weight will open the valve d² when the water in the "chamber
a bas

and then passes down through the cup 8 and the diaphragm i The cup or weight 8
is connected rigidly to the float r by the rods s¹ The super-diaphragmatic portion

lettering of the parts being the same both in figures 5 and 6.

The action of the apparatus shown at Figure 5 is as follows, in filling, its action
is the same as that described in reference to Figure 4 but when the level of the
water raised reaches the float r the float r by rising initiates the closing of the

the valve d the same action opens the air inlet valve g and the contents of the
" chamber a are then discharged through the syphon discharge pipe n As the
water level falls in the "chamber" a it leaves the float r (which is held) in its
raised position by the vacuum in the valve d' (If advisable the suspension of the
float may be helped by a balance weight on the float r) until the level of the cup
weight 8 is reached when as the water still recedes the weight of the combined
apparatus s which is sufficient to overcome the vacuum in the valve d' draws down
the float closes the valve g and re-establishes the exhaust communication between
the "chamber" a and the draw pipe d through the port d³ of the valve d³. The
continuous action of the syphon bed as described in reference to Figure 4 and the
closure of the " Chamber a by the non return valve n¹ enables the "chamber." a to
be again exhausted and filled in the manner before described And the operations
of filling and emptying the "chamber" a is continuous and automatic.

invention and in what manner the same is to be performed I declare that what
