PROVISIONAL SPECIFICATION left by the said Edward Laker Voice at the
Office of the Commissioners of Patents on the 15th January 1879.
EDWARD LAKER VOICE, of 1, Francis Street, Torrington Square, in the County
of Middlesex. "IMPROVEMENTS IN APPARATUS FOR CONTROLLING, REGULATING,
MEASURING, AND ARRESTING THE FLOW OR DISCHARGE OF LIQUIDS AND FLUIDS,
AND PREVENTING WASTE THEREOF."
My Invention specially relates to apparatus employed for controlling, regulating,
measuring, and arresting the flow or discharge of water from cisterns, reservoirs,
and other sources of water supply, and has for its main object the actuating of
various kinds of valves used for such purposes by hydrostatic pressure, whereby I
am enabled to construct various apparatus suitable for the above purposes in a
more simple and economical way than has been done hitherto. This I effect as
follows: I construct a vessel in preference round or oval with a flat top and
bottom, which I make either of iron, zinc, copper, brass, lead, glass, or earthenware;
the said vessel to have a movable diaphragm which is connected with the said
vessel by means of any waterproof flexible substance suitable for such purpose,
which cuables the diaphragm to move to and from the said vessel, similar to a pair
of bellows. Instead of having the diaphragm to move the bottom, or any part of
the side of vessel, could be made to act in the same manner, with the same effect,
and there is no necessity why the said vessel should always be made shape aforesaid,
as it would answer if made in a variety of shapes.
In the said vessel I place a valve, which is connected to the pipe which leads to
the reservoir or cistern, and which said valve is actuated either in a direct manner
or by means of leverage, by the diaphragm, bottom, or side, as the case may be,
and which causes the valve to open and close when the said diaphragm is moved.
Leading out of the vessel is a pipe which conducts the water after passing through
the valve to the required place, the water continuing to run until it rises to a
certain height above the level of the said diaphragm, when it exerts an outward
pressure in the vessel which causes the said diaphragm to move outwards with a
[Price Gd

page_text: certain force, closes the said valve, and consequently stops the water from running.
I propose to utilise this form of my Invention in all cases where a supply cistern
and ball or float valve is now used. In cases where my apparatus would be used
above the ground floor of houses, if necessary, there could be a small pipe inserted
in the diaphragm, or in the side of said vessel, when, in case of the valve leaking,
the water would flow up said pipe, which could then be turned into a waste pipe.
My Invention is also applicable to apparatus for preventing waste of water.
In this case, the vessel before alluded to would be made considerably larger,
to hold, say, two gallons of water, and would have a pipe inserted in the side
at the top of vessel, or in the moveable diaphragm pointing upwards, say, three or
four inches high. In the said vessel I place an inlet valve connected to the pipe
from reservoir, and in the bottom of vessel I place another and larger outlet valve; this
valve is connected to the diaphragm by a loose chain, wire, or rope, or linked rod,
and the inlet valve is actuated either in a direct manner or by any suitable means
by the said diaphragm, and is so arranged that when the outlet valve is open, the
inlet valve is shut, and vice versa. The diaphragm is actuated by means of a chain,
wire, or rope passing over a wheel, or by a combination of levers, and passed down
the pipe at the top of vessel. Supposing then the vessel to be full of water, the
diaphragm is pulled up by the consumer by means of the chain or levers, which
being connected to the outlet valve, causes that to open, and the vessel is emptied
of its contents at the same time the inlet valve has closed itself. As soon as the con-
sumer lets go the chain or levers the lid descends, bottom valve closes, the diaphragm
then coming in contact with the inlet valve, which causes it to open when the
vessel is once more filled with water, which then rises up the pipe at top of vessel,
and exerts an outward pressure on the under surface of the said diaphragm, which
causes it to rise, and enables the inlet valve to once more close. In the bottom
valve I place an air pipe which I carry up, and which stands in the said pipe at top
of vessel which will answer a double purpose, viz., as an air pipe and waste pipe,
by being cut off at the required height.
My Invention is also applicable to other liquids, and can be applied to water-
closets, urinals, & lavatories.

EDWARD LAKER VOICE, of 1, Francis Street, Torrington Square, in the County
of Middlesex. "IMPROVEMENTS IN APPARATUS FOR CONTROLLING, REGULATING,
MEASURING, AND ARRESTING THE FLOW OR DISCHARGE OF LIQUIDS AND FLUIDS,
AND PREVENTING WASTE THEREOF."
My Invention specially relates to apparatus employed for controlling, regulating,
measuring, and arresting the flow or discharge of water from cisterns, reservoirs,
and other sources of water supply, and has for its main object the actuating of
various kinds of valves used for such purposes by hydrostatic pressure, whereby I
am enabled to construct various apparatus suitable for the above purposes in a more
simple and economical manner than has been done hitherto. This I effect as
follows: I construct a vessel in preference, round or oval, with a flat top and
bottom which I make either of iron, zinc, copper, brass, glass, or earthenwaro; the
said vessel has a moveable diaphragm which is connected with the said vessel by
means of any waterproof flexible substance suitable for such purpose, which enables
the diaphragm to move to and from the said vessel similarly to a pair of bellows.
Instead of the diaphragm being moveable, the bottom or any part of the side of the
vessel could be made to act in the same manner, with the same effect, and there is
no necessity that the said vessel should always be made of the shape shewn, as it
would answer if made in a variety of shapes.
In the said vessel I place a valve which is connected to the pipe which leads to
the reservoir or cistern, and which said valve is actuated either in a direct manner,
or by means of leverage by the diaphragm, bottom, or side, as the case may be, and
which causes the valve to open and close when the said diaphragm is moved.
Leading out of the vessel is a pipe which conducts the water after passing through
the valve to the required place, the water continuing to run until it rises to a
certain height above the level of the said diaphragm, when it exerts an outward
pressure in the vessel which causes the said diaphragm to move outwards with a
certain force so as to close the valve, and consequently stop the water from running.
I propose to utilize this form of my Invention in all cases where a supply cistern
and ball or float valve is now used. In cases where my apparatus would be used
above the ground floor of houses, if necessary, there could be a small pipe inserted in
the diaphragm or in the said vessel, when, in case of the valve leaking, the water
would flow up the said pipe, which could then be turned into a waste pipe.
It will be seen that my Invention is based on the principle of the hydrostatic
paradox, namely, that if a vertical tube is inserted in a vessel which is otherwise
closed, and which is of a certain area, it follows that if it be filled with liquid until
it rises to the height of the tube that it will exert a pressure on the base of the
vessel, which is equal to a weight of liquid whose volume would be the area of the
vessel multiplied by the height of the pipe or a column of liquid which is indicated
by dotted lines, Figure 1; and I will now proceed to explain the different parts of
my apparatus just herein-before referred to. Figure 2 is a section shewing the
application of my Invention in connection with a kitchen boiler supply valve;
A, A. A, A, is a vessel made of the aforesaid substance, or it can be made of
porcelain, china, or other suitable material or materials; D is the moveable
diaphragmn connected with the vessel by means of vulcanized india-rubber, leather,
or other suitable flexible substance D, and which said diaphragm D actuates the
valve V; I prefer to have this diaphragm D of sufficient weight to open the valve V
when the said diaphragm is not under pressure; P is a fixed diaphragm, the object
of which is to absorb the momentum of the water as it comes from the valve V,
and which causes the water to pass between the edge of the diaphragm P and the
side of the vessel as indicated by the arrows. This fixed diaphragm P is of

page_text: particular importance in this apparatus inasmuch that it prevents the force caused
by the velocity of the water from affecting the moveable diaphragm D. Although
almost any kind of valve may be used in this apparatus I prefer that kind known
as the equilibrium valve. Instead of having the water to pass between the edge
of the diaphragm P and the side of the vessel I sometimes use a substance such as
perforated zinc, and cause the water to flow through various perforations distributed
over a large area. The action of this apparatus will be readily understood from the
explanation herein-before given.
My Invention is also applicable to apparatus for preventing waste of water. In
this case the vessel before alluded to would be made considerably larger, to hold,
say, two gallons of water, and would have a pipe inserted in the vessel or in the
moveable diaphragm, and extending, say, three or four inches above the same.
In the said vessel I place an inlet valve connected to the pipe from the reservoir, and in
the bottom of the vessel I place another and larger outlet valve; this valve is connected
to the diaphragm by a loose chain, wire, or rope, or linked rod, and the inlet valve
is actuated either in a direct manner or by any suitable means by the said
diaphragm, and is so arranged that when the outlet valve is open the inlet valve
is shut, and vice versa. The diaphragmn is actuated by means of a chain, wire, or
rope passing over a wheel, or by a combination of levers, and passed down the
pipe at the top of the vessel. Supposing then the vessel to be full of water,
the diaphragm is pulled by means of the chain or levers, which, being connected
to the outlet valve, causes that to open, and the vessel is emptied of its contents,
at the same time the inlet valve has closed itself; as soon as the chain or levers
is or are released the lid or diaphragm descends, the bottom valve closes the
diaphragm, then coming in contact with the inlet valve, which causes it to open,
when the vessel is once more filled with water, which then rises up the pipe at
the top of the vessel, and exerts an outward pressure on the under surface of the
said diaphragm, which causes it to rise and enables the inlet valve to once more
close. In the bottom valve I place an air pipe, which I carry up, and which
stands in the said pipe at the top of the vessel, which will answer a double purpose,
namely, as an air pipe and waste pipe, by being cut off at the required height.
Figure 7 is a section of this construction of waste preventer; A, A, A, A, is the
vessel, which may be constructed of the same material or materials as apparatus
before mentioned in Figure 2; V is the inlet valve; W is the outlet valve; D is
the moveable diaphragm or lid; P is the hydrostatical tube or pipe; R is a rod,
which is fixed in the pipo P by means of a thumbscrew T; C is a cord, chain, or
an equivalent; L is the lever for actuating. I will here repeat the action. Sup-
posing the vessel to be empty, the water enters through the inlet valve V, fills the
vessel and rises up the pipe P, when it exerts a hydrostatical pressure on the under
surface of the diaphragm or lid D, which enables the valve V to close. On the
diaphragm being raised by the lever L the bottom valve is opened, and the vessel
is emptied of its contents. The air pipe is indicated by dotted lines, and is inserted in
the bottom valve or in the down pipe in any well-known manner; Figures 3, 4, 5,
and 6 show different ways in which the diaphragm may be connected to the vessel.
Figure 8 is another arrangement of my Invention where I cause the pipe P to
act as a fulcrum for actuating the diaphragm; in this case the rod R, Figure 7, may
be dispensed with, and both the inlet and outlet valves may be connected to the
diaphragm or lid by means of a chain or its equivalent. Figure 9 is another
adaptation of my Invention, the action of which will be readily understood from
the following description :-X, X, is a tube or pipe inserted in a diaphragm D; this
diaphragm is fixed to a small chamber similar to the apparatus hercin-before
described, and which stands in the vessel, and which in this case contains air, and
is open to the atmosphere through the pipe X, X, and also to the down pipe by
passage R. Water enters through the valve V, and fills the vessel, when it exerts
a certain pressure on the diaphragm D, which causes it to descend, bringing with
it one end of the lever L, which enables the valve V to close; W is a weight
which opens the valve and lifts the diaphragm D when the lever B is released.

page_text: Upon the lever B being actuated it opens the bottom valve and raises the weighted
lever L when the vessel will be emptied of its contents.
Figure 10 is another arrangement; D is a diaphragm fixed to a chamber or
receptacle C, which contains air, and is open to the atmosphere by means of the
tube or pipe P; R is a rod, which is fixed to the diaphragm D, the object of which
is to actuate the lever L, of the valve V. The action is as follows:-Supposing the
vessel to be empty, water enters at valve V, and continues to rise in the vessel
until it exerts a sufficient pressure on the under surface of the diaphragm D to lift
the weighted lever L when the inlet valve V closes; upon the bottom valve being
raised by means of the lever B, the lever L is raised as well, and the vessel is emptied
of its contents, and no more water can run until the lever B is once more released; it
is so arranged that the bottom valve must be closed before the inlet valve V is
opened. Figure 11 is another arrangement; D is a diaphragm connected to the
base in a manner herein-before explained; P is a pipe connected to the said
diaphragm; C and H, H, is a chamber and pipe which stands over and surrounds
the diaphragm D and pipe P.
The action of this apparatus is as follows:-The pipe P is first filled with water
when it exerts a hydrostatic pressure on the under surface of the diaphragm D,
which opens the inlet valve V. Water is prevented from entering the chamber
which surrounds pipe P by means of a valve A, consequently the water continues
to rise until it reaches the top of the chamber H, H, when it immediately runs
over and fills the space which was previously occupied by the atmosphere between
the pipe P and chamber H, H, thereby causing an equilibrium of pressure on the
diaphragm D, which then descends by gravitation, plus the pressure of the water on
the inlet valve V; as soon as the lever B is actuated the bottom valve is opened,
and the diaphragm D is kept down by means of the projection U pressing on a
cross bar Y; the vessel is then emptied, and the water which was contained.
between the chamber H, H, and the pipe P then runs out of the valve A while the
water remains in the pipe P. On releasing the lever B the bottom valve will be
closed, and the water contained in the pipe P will exert an upward pressure on the
diaphragm D, and thereby open the valve V when the vessel is once more filled
with water.
I widen the orifice of the pipo P to create more volume and to act as a reservoir
for diaphragm D. Figure 12 is another form of water waste preventor, inasmuch
that it stops the supply from the main as soon as any waste takes place which may
have been caused by the leaking of different valves in various parts of buildings.
D is a diaphragm which is fixed to a base of nearly or the same size and shape, by
preference round, in a manner herein-before explained. H, H, is a tube or pipe
which is fixed to and rises and falls with the diaphragm D; P is the overflow pipe;
O is the pipe which conveys the water from the overflow pipes of different cisterns
in various parts of buildings; R is the rising main pipe; X is a standard or stay
which firmly fixes the valve V, and the other end of which is fixed to the apparatus
at bottom. The action is as follows:-Assuming that a leakage has occurred in one
of the valves which supply the cisterns, the water which would consequently run
to waste would be conveyed down the pipe O when it would rise up the space
between the pipe P and the tube H, H, and cause a hydrostatical pressure on the
under surface of the diaphragm D which would then rise and close the valve V,
thereby stopping the supply from the main. C is a cock, tap, or other suitable
contrivance for letting the water out of the apparatus.
I will here remark that any suitable known arrangement for producing an after-
flush may be applied to my improved water waste preventer, such for instance as a
self-closing valve actuated by the bottom valve of iny apparatus.
In carrying out my Invention, which more particularly relate to the measuring of
liquids in that class of apparatus known as water meters,―
I construct a vessel in preference round, and which has affixed to the top a
moveable diaphragm or diaphragms with a hydrostatical pipo similar to Figure 7

page_text: and Figure 8. The said vessel is divided into two or more compartments by a fixed
partition or partitions which may be placed about one-third of the height of the
vessel from the top. The partition or partitions is or are provided with a valve or
valves, which said valve or valves is or are actuated by means of a hydrostatic
diaphragm or diaphragms at or near the bottom of vessel or chamber, and which
may be connected to the valve or valves by means of a tube, or rod, or other suitable
appliance. In the bottom of the vessel is an outlet valve or valves which may be
connected to the diaphragm or diaphragms at the top of the vessel by a rod, wire,'or
chain, or an equivalent. In the said partition a tube or pipe is fixed which stands in the
hydrostatical pipe at top of vessel, the object of which is to convey air to the lower
chamber of the vessel, and which also provides the means of communication from
the diaphragm or diaphragms at top of vessel to the bottom valve or valves. The
diaphragm or diaphragms for actuating the valve or valves in the partition or
partitions is caused to act by means of hydrostatic pressure through being connected
by a tube or tubes with the upper chamber. The said valve or valves in the
partition may be provided with a lever, levers, or other suitable mechanism, the
object of which is to keep the valve or valves open by means of the weight of
the diaphragm or diaphragms at the top of vessel when the said vessel is filling with
liquid. In the upper chamber I place an inlet valve or valves which is or are opened
and closed by means of the diaphragm or diaphragms at top of vessel, and is
arranged in such manner that the vessel must be emptied, or partially so, of a
uniform quantity of liquid before the said inlet valve or valves can be opened by
the said diaphragm; this is or may be effected by a ratchet and pinion, or by various
other mechanical equivalents. The action of this apparatus will be understood by
referring to Figure 13, which is a section of this construction of apparatus. A, A, A, is
the vessel or case; Y is the fixed partition; D is the moveable diaphragm at top of
vessel; P is the hydrostatical pipe; D, D, X, X, shew the hydrostatical diaphragm
and tube for actuating the valve V in the partition; O is the outlet valve; W is the
inlet valve; T is a tube fixed to the partition which stands in the pipe P. Water
enters at the valve V, V, and runs down the tube X, X, which causes the valvo V
to rise when the liquid runs through that valve into the bottom chamber of
vessel O, O, which is then filled with liquid, thereby causing an equilibrium of
pressure on the diaphragm D, D, which causes the valve V to close, the water or
liquid then immediately fills the upper chamber and rises in the hydrostatical pipo P,
thereby lifting the diaphragm D which opens the outlet valve at bottom and closes
the inlet valve V, V. As soon as a certain quantity of liquid has passed out of the
vessel the diaphragm D, D, opens the valve V and the water or liquid then passes
from the upper to the lower chamber, thereby causing the top diaphragm to full,
which enables the bottom valve to close; the diaphragm then comes in contact with
the inlet valve V, V, which enables that to close.
The quantity of water which this vessel discharges at each time may be regulated
by putting more or less weight on the diaphragm D, D. W is a weighted lever
which opens the valve V, V.
Figure 14 is a section of a double-action meter, and is arranged for one vessel to
be filling while the other is emptying. The inlet valve V, V, in this case is made
to close one orifice while the other is open. The bottom or outlet valve is made of
sufficient weight (as shewn) in one vessel to open the valve in the other when the
top diaphragm is down; or these valves may be detached and a chain or wire could
be passed through the pipe O and so actuate the valve. Sometimes instead of using
the kind of valves shewn I use slide, hinged, or other suitable valves or cocks, and
dispense with the levers W and L, and instead of having the diaphragm D, D, to
actuate the valve V, I sometimes employ a float of nearly the same weight as the
water which it displaces, and by means of leverage so actuate the valve V. The
rising and falling of the diaphragm at the top of vessel may be communicated to
an indicator or counter in any well-known manner, thereby registering the amount
of liquid passed in a certain time.
My apparatus shewn in Figure 2 may be fitted to this meter or a modification of

page_text: the same, thereby stopping the action of the said meter when the cistern to which
the liquid is conveyed is sufficiently full.
Instead of having the hydrostatical tube in the diaphragm at top I may some-
times cause it to be connected to the vessel and actuate the bottom valve or valves
by mechanism outside of the vessel and obtain the same result.
In carrying out my Invention as applied to waterclosets I construct two discs
made of thin metal or of other suitable material or materials, in shape by preference
round. In the the top disc I insert a hollow tube which constitutes the spindle of the
supply valve; the two discs are connected to each other in a manner herein-before
explained which enables them to collapse and expand. In the tube I place a valvo
which enables the water to be forced out of the space between the discs without
allowing it to return otherwise than by its passing through a small orifice which
may or may not be made in the valve, instead of which a cock, tap, or other suitable
appliance may be used, or a valve as shewn in Figure 15. At the top of the tube,
in the chamber of the supply valve, I make one or more orifices open to the pipe
which conveys the water to the basin. The action of this apparatus will be under-
stood by referring to Figure 15 which is a section of my apparatus as applied to a
seat-action closet. D, D, are the collapsing discs or diaphragms; P is the hollow
tube;
V is the supply valve; A is the retarding valve. Upon the lever L being
depressed by the seat S it presses the bottom disc or diaphragm D upwards, thereby
forcing the water up the tube P. As soon as the seat is allowed to rise the whole
apparatus, with the exception of the supply valve V, falls bodily, thereby opening
the supply valve V, when the water gradually fills the space between the diaphragms
or discs and closes the supply valvo V. It will be seen that this form of my apparatus
is an effectual waste preventer. Figure 16 is another form of my apparatus fitted
to a pan closet; the tap, cock, or valve V is actuated by the handle of the closet,
thereby letting the water out of the diaphragms D and so opening the valve V. C is
a cock to regulate the closing of the valve.
In this form of my apparatus instead of having the water to pass through the
tube which constitutes the spindle of the supply valve that could be made solid, and
the diaphragms or collapsing chamber could be connected to the pipe which leads to
the closet by means of a separate tube or tubes. Figure 17 is a section of my
apparatus fitted to a pan closet and actuated by mechanism, the object of which (on
the handle being raised) is to raise the lever La certain height by means of the bar B
when it slips off and drops on bar D, thereby opening the valve V. As soon as the
handle is lowered the lever L is let down to its full extent, which enables just
enough water to pass through the valve V to seal the closet pan. I do not confine
myself to the precise method of obtaining this object in connection with my apparatus
as it can be done in various ways. Figure 18 is a section of my Invention fitted to
a valve closet; Figure 19 is a section of my apparatus to act as an ordinary valve
regulator only. The handle is raised, the top diaphragm or disc then being depressed
and the supply valve opened. As soon as the handle is left to the hydrostatical
pressure on the under surface of the top diaphragm caused by the water running
down the tube P forces it upward and closes the supply valve. Figure 20 is another
arrangement where I cause the supply valve to be fixed as close to the diaphragm as
is consistent, thereby dispensing with the length of tube P, and I utilize the water
contained in the pipe which leads from the supply valve to the basin to act as the
hydrostatical column. This form is equally applicable in all cases mentioned as
regards waterclosets, and is also applicable to lavatories. Fig. 21 is a section of my
apparatus as applied to lavatories, the only difference being in the various ways of
actuating. I sometimes employ mercury instead of liquid in this form of my
Invention; in that case the tube P is provided with a receptacle or chamber at the
top, and is of the same volume (or larger) than the diaphragm at bottom, the
mercury can then be forced from the diaphragm up to the receptacle or chamber,
the action then being the same as apparatus in Figure 15 in connection with water,
the only difference being that the orifice in the valve chamber V is dispensed with.

page_text: Other liquids and fluids may be used in this form of my. apparatus from the fact
that it is separated from the water which supplies the closet or basin.
I sometimes use a flexible tube or tubes in connection with a diaphragm or
diaphragms in place of pipe P, Figure 15, and by contracting and expanding tho
same by suitable means cause the liquid or fluid to rise and fall in the said tube or
tubes in proportion to the amount of contraction and expansion, and thereby
cause a greater or lesser hydrostatic pressure between the said diaphragın or
diaphragms, which said diaphragms can be made to actuate valves, or instead of
contracting and expanding the tube or tubes I may cause it or them to be raised
and lowered, and thereby attain the same object.
My Invention is also applicable to other liquids, and can be applied to waterclosets,
urinals, and lavatories.
Having now fully described the nature and object of my said Invention of
improvements in controlling, regulating, measuring, and arresting the flow or
discharge of liquids and fluids, and preventing waste thereof, and the manner in
which the same is to be or may be carried into practical effect, I should like it to be
understood that I do not confine or limit myself to the precise details and modifica-
tions shewn in the accompanying Drawing, as the same may be modified without
departing from the nature of the said Invention, nor do I confine myself to the precise
number or kind of valves which I may use in any of my apparatus, as it is evident
that two or more valves could be actuated equally as well as one in every case;
but what I claim is,―
Firstly. The general arrangement and construction of kitchen boiler supply
apparatus operating substantially as herein-before described, and illustrated in
Figure 2 of the accompanying Drawing.
Secondly. The construction and employment of a hydrostatical tube or tubes in
combination with a moveable diaphragm or diaphragms, such tube or tubes being
fixed to or forming part of and moving with the said diaphragm or diaphragms for
actuating the valves or cocks of water wasto preventers, liquid meters, waterclosets,
urinals, lavatories, and analogous purposes, as herein-before described.
Thirdly. The general arrangement and construction of water waste preventers,
operating substantially as herein-before described, and represented in Figures 7, 8,
9, 10, 11, and 12 of the accompanying Drawing.
Fourthly. The general arrangement and construction of liquid meters, operating
substantially as herein-before described, and represented in Figures 13 and 14 of the
accompanying Drawing.
Fifthly. The general arrangement and construction of apparatus for regulating
the flow of water to waterclosets, and preventing waste thereof, operating sub-
stantially as herein-before described, and represented in Figures 15, 16, 17, 18, 19
and 20 of the accompanying Drawing.
Sixthly. The general arrangement and construction of apparatus for supplying
water to lavatories and preventing waste thereof, operating substantially as herein-

In witness whereof, I, the said Edward Laker Voice, have hereto set my hand
and seal, this Twenty-second day of April, in the year of our Lord One
