I WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, & Co Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :—
This invention relates to apparatus chiefly designed for supplying water to water
closets urinals and other arrangements of fixtures employed in the water systems
of dwelling houses, hotels and other buildings.
The class of such apparatuses to which this invention is particularly applicable
is one that is well known and in common and general use, and for the present
purpose may be described generally as an apparatus in which is used, first, a valve
to open the discharge-pipe of the water-tank or reservoir, and leading therefrom
to the water-closet bowl or the like for the supply of water to said bowl, and to
close it against said supply of water; and second, an air and over-flow pipe, as it
is generally known, for the overflow of water from the tank when the water rises
above a given, or stated, level therein, and for its delivery into the discharge pipe
of the tank, at a point below the seat of the valve to said pipe before referred to;
this air and overflow pipe is at all times open, both, to the tank, just above the
given or stated water level therein, and to the discharge pipe of the tank, and
consequently permits the escape of air at all times, and the escape of the water of
the tank, at the particular time stated.
This invention more particularly pertains to apparatus, such as above described,
in which a chambered or float-valve is used, having water and air-passages for the
ingress and egress of water and air, but as will be apparent from the description
which follows, this invention, in some, if not all of its features, is applicable to
valves of other forms and arrangements and therefore it is not intended to limit it,
in that regard.
The said invention consists:-
First, of the combination with the discharge-pipe of a water-tank, or other
suitable supply, leading to the bowl of a water-closet, urinal or the like of a

page_text: chambered and float valve which has an air passage leading from its upper portion
down and into the discharge pipe, and is in communication with both the chamber
of the valve and the passage of said pipe, and of an opening or passage, for the
flow of the water of the tank into and out of the chamber of the valve and for its
discharge into said discharge-pipe, or other suitable discharge.
Second of mechanism for opening the valve of the discharge-pipe, leading from
the tank to the water-closet bowl or the like for the delivery of water through
said pipe to said bowl, and for causing or permitting the valve to close said pipe
to the passage of the water through it to said bowl, according as the connection
between said mechanism and the valve, is a rigid or a flexible oue, as for instance,
a wire, rod, or chain. This mechanism consists, in substance, of two levers, one of
which is connected directly to the valve and the other to the operating mechanism
or device at the water-closet, urinal or the like, and through which the power for
operating the valve is applied. Each lever is constructed and the two are arranged
in relation to each other as hereinafter fully described, and all in a manner to
secure in both the forward and backward movements of the operating lever,
connected to the operating mechanism or device at the water-closet, urinal or the
like, a movement of the lever connected to the valve in the same direction, and
that the proper direction to open the valve, and otherwise to secure or to permit
the close of the valve.
Third in the combination with the discharge-pipe of a water-tank, or other
suitable supply, leading to the bowl of a water-closet, urinal or the like, of a
partition or wall, such for instance, as a plate which is located in the water-passage
of said pipe, and is arranged and is made capable of adjustment therein, for the
size or area of said water-passage to be readily changed and adjusted, or regulated,
to the quantity of water desired to be discharged through said pipe to the bowl in
a given time.
Fourth, in the combination with a water-tank, of a chambered and float-valve
having an air-passage leading from its chamber into the water-passage of the
discharge pipe of said tank, and extending below the seat of the valve of said pipe
and of a partition or wall, such for instance as a plate, which is located in the
water-passage of said pipe, above the point of discharge of air from the float-valve
into said water-passage and between said point of discharge and the seat of the
valve. The said wall is preferably made capable of adjustment and constructed
and arranged to reduce the area of said passage to an area equal to or less than
the area of the water-passage of the discharge-pipe, so that below said partition,
and for a greater or less portion of its length the discharge pipe will be of an area
less than the area of the water-passage before it is reduced, as stated, at the
location of said partition.
In the accompanying drawing,
Figure 1 is a central longitudinal vertical section through a water-tank, an over-
flow and an air-pipe combined in one, and a discharge-pipe and its valve; and
showing in elevation the operating and valve-levers for the valve of the discharge-
pipe, in their normal position and said valve closed.
Figure 2, is a horizontal section on the line 2-2, figure 1.
Figure 3 is a plan view of the apparatus, shown in figure 1.
Figures 4 and 5, are front elevations showing the operating and valve-levers in
their different positions as they are worked and as will hereinafter fully appear.
Figures 6, 7 and 8 are views, illustrating modifications hereinafter described.
A is a water-tank; B is a discharge-pipe leading from the bottom of the tank
and connected to a water-closet bowl or the like, C is the overflow and air-pipe in
communication with the external air, just above the stated or given level at A³ of
the water in the tank, and with its water-passage connected with the discharge-
pipe just below its communication at E, with the water-tank, all as usual, in the
water-systems of dwelling-houses, hotels, and other buildings.
D is a hollow or chambered float-valve, made of sheet metal, or other suitable
material, and of any suitable shape, as for instance, hemispherical; and having a

page_text: seat on its flat side F (provided with a washer or other packing disc a of leather or
other suitable material) upon the upper edge or rim surrounding the opening E of
the discharge-pipe B of the tank.
This packing or washer a secures close contact of the valve with its seat, when it
is resting thereon, and the valve when seated, extends or laps beyond the sides of
the opening E of the discharge-pipe.
The valve when seated is below the water level and wholly submerged in the
water in the tank, and when so seated the discharge-pipe is closed to prevent the
passage through it of the water in the tank.
L is a vertical tubular air-passage of the valve. This air-tube leads downward
from a point near the top of the chamber J of the valve through a water-tight
opening in the flat side F of the valve D, and thence through and below a fixed
concentric guide-collar M of the discharge-pipe, and below this collar the tube is
provided with a collar N forming a shoulder thereon.
The guide-collar M is open around and between it and the inner vertical wall of
the discharge-pipe, to allow the water from the tank to pass down and through
said pipe; and the air-pipe L is open at each end, communicating, at its upper end,
with the valve-chamber J, and, at its lower end, with the water-passage of the
discharge-pipe, but otherwise, it is closed air-tight, in every respect, to said chamber
and said pipe.
The air-tube L and collar M guide the valve in its upward and downward
movement for the opening and closing of the water-passage B, and the shoulder
made on the tube by the collar N limits the upward movement of the valve.
H is an opening through the flat side of the valve and forming communication
between its chamber J and the water-passage of the discharge-pipe, when the valve
is closed. This opening is for the passage of the water from the tank, into and out
of the valve-chamber, as will hereinafter fully appear.
O is a vertical stem, wire or rod which at its lower end is hung to a fixed stud or
head b at the centre of the upper and convex side of the valve D, and at its upper
end is hung to one end of a lever R turning upon a fixed horizontal fulcrum pin k
of a stationary standard or upright S, either supported, as shown, upon the top of
the water-tank, or upon any other suitable support therefor. This lever at rest and
in its normal position (figures 1 and 3) rests by its lower edge j upon a fixed abut-
ment or support T3 of the standard S, and in this position of the lever, the valve is
on its seat on the discharge-pipe B closing said pipe, as before stated, to the passage
of water from the tank.
The lever R is the "valve lever," of the operating levers of valve, and will be
hereinafter so called, for convenience of description.
A and T are two noses or projections extending upward from the upper edge d
of the valve-lever a notch or depression P being between and separating them.
These projections A, T, in the operation of the levers, to be hereinafter described,
present three working and bearing surfaces or edges f2 m and n.
The bearing surface f2 is on the projection A2, and it is more or less horizontal
and continued in the bearing surface n, which is more or less vertical. This
surface n forms one vertical side of the notch or depression, P, between the two
projections A, T, and has opposite to it the bearing surface m of the projection T,
which surface forms the other vertical side wall or boundary of the notch P, and is
more, or less, vertical.
U is a lever, hung as shewn, by a vertical slot or elongated bearing q upon a
horizontal fulcrum pin r of the upright S. This lever U is located above the
valve-lever R, and its fulcrum pin is between the fulcrum pink and the end g of
the valve-lever connected to the valve. This lever U is the "operating lever" and
will be hereinafter so called, for convenience of designation, or description.
The operating lever U, at the outer end of the arm X, is connected to any
suitable operating device, as for instance, to the floor, door, or seat of a water-
closet, or to a handle, knob or other pull, and between its end so connected, and its
fulcrum pin r, said arm of the operating lever has a cylindrical nose or knob C²,

page_text: projecting horizontally from one side thereof and over and across the upper edge d
of the valve lever.
This nose C in the operation of the levers, to be hereinafter described has three
working or bearing surfaces, or points d³, b*, a²; two of these points a², 6ª, are on
the opposite sides of the nose C³, and, one d² is located between said two surfaces,
joining them at their lower ends.
This nose C with its said bearing surfaces d2, b, and a², is situated on the
lever U in relation to the three bearing surfaces f³, m, n of the valve-lever before
described, so as to present (with the operating lever in its normal position, and at
rest with its upper edge against the fixed abutment B*, of the upright S, and the
valve lever in its normal position and at rest with the lower edge ; upon its fixed
abutment T2) its working or bearing surface d toward the bearing surface f² of
the nose A2 of the valve-lever; and in this presentation of the working surface d³
of the operating lever U, to the working surface f2 of the valve-lever K, the other
working surfaces m and n and the notch P of the valve-lever R are between such
position of said nose C³, and the fulcrum pin r of the operating lever, (Figure 1).
Y is a weight applied to the arm V of the operating lever opposite to that,
connected, as described, for the working of the lever. This weight is fastened by
a thumb-screw G or is arranged otherwise in any suitable manner for being
adjusted and set in position upon the arm of the lever, as it may be desired, to
increase or decrease the force or power of the leverage thereof.
e is a fixed vertical projection from upright S, and is located between the
operating and valve-levers and their fulcrum pius r, k. The upper horizontal
edge of this projection, in the operation of the levers, serves as a fulcrum for the
operating lever, all as will hereinafter fully appear.
By pulling downward the arm X of the operating-lever which is provided with
means as described for so working said lever, its opposite arm V is raised against
its weight, and in this movement of the operating-lever the bearing surface d² of
its nose C works downward against the upper horizontal surface f2 of the
projection A2, which surface is at one side of the fulcrum of the valve-lever, and
thereby raises the other arm Q of said valve-lever, to which the valve is hung, and
through it the valve.
By the continued movement of the two levers, the nose C2 of the operating lever
escapes at its said bearing d from its bearing f' upon the valve-lever R, and
entering into the notch P of the valve-lever, comes, by its vertical bearing surface b²,
against the vertical bearing surfaces of the nose T of said valve-lever and pressing
thereon toward the end of the lever, connected to the valve, forces the valve-lever
to its seat upon its abutment T3, closing the valve and stopping all further move-
ments of the operating lever in the direction stated.
During this working of the bearing surface b³ of the nose C2 of the operating lever
against the bearing surface m of the valve-lever, as above described, and just before
it is completed, the operating-lever comes to its fulcrum-rest e thus lengthening
the arm thereof to which the weight is applied, which aim in the return movement
of the operating-lever acts to again lift the valve-lever and its valve as hereinafter
described, secures an increased leverage thereof on the valve-lever and valve with
a decreased length of travel of the end of the operating-lever to which, the
operating device, such as a water-closet seat &o, is connected.
The elongated bearing g of the operating-lever upon its fulcrum pin r, allows
when this change of the lever to the fulcrum bearing e occurs, a working of the
lever thereon in its further movements.
On the release of the operating-lever, it is moved backward, by the weight of its
weighted arm turning then on its supplementary fulcrum e as a bearing, and
having increased leverage thereby, and by the then bearing and working of the
vertical bearing surface a² of its knob, or nose C2, upon and against the vertical
bearing surface n of the nose A2 of the valve-lever, secures a lifting of said lever at
its end connected to the valve, and another opening of the valve, until by the
continued movement, it comes to a position of rest against its abutment B², which

page_text: brings the nose or knob C3 by its bearing surface d² again in position for operation,
as described, upon the horizontal bearing surface of the nose A' of the valve-
lever, in the next downward pull upon the arm X of the operating lever, and
leaves the valve-lever free to come to its rest upon the abutment therefor, from
the then closing of the valve, as will be hereafter described.
From the above description, it is apparent, that a continuous downward pull
upon the arm X of the operating lever U secures, first, by the working of the '
bearing surfaces d², f³, of it and of the valve lever, a lifting of the end g, of the
valve lever, to which the valve is hung, and a consequent lifting of the valve from
its seat, and second, an escape of such surfaces, one from the other, and a then
working of the bearing surfaces 62, m of said levers, which force the valve lever to
its rest on its abutment T2, and with a rigid connection of the valve to said lever,
thereby positively securing a closing of the valve upon its seat, followed by the
then return of the operating lever, if the force applied to it to pull its end
downward, as described, is removed which, by the working of the bearing surfaces
a, n, of the levers, again secures a lifting of the end g of the valve-lever, and of
the valve, until said working surfaces pass from their contact and the operating
lever has come to a rest against its abutment B2, leaving the valve-lever and its
valve free, the one to return to its rest on the abutment T and the other to close
on its seat.
In Figure 1, as before stated, the levers R and U are shewn in their normal
position, with the valve closed; in Figure 4, they are shewn in position just after
their bearing surfaces d, f, have escaped from each other with the valve lever
raised, and securing the first opening of the valve and their bearing surfaces b³, m,
in position to work for the depression of the end g of the valve lever on a continued
downward pull upon the end h, of the operating-lever; and in Figure 5 they are
shewn in position after the valve-lever has been forced to its rest T2 and the valve
closed, and the operating lever has finished its downward movement at its end h,
and is in readiness, on the return movement of said end, of the operating lever,
by the action of the weighted arm V thereof, for the working of the bearing
surfaces a², n³, of the levers to again raise the valve-lever and through it the
valve.
When the valve is lifted from its seat, opening the discharge pipe B of the tank,
in the first operation of the levers R, U, above described, to raise the valve-lever
as the connection O between the valve and its lever, is a rigid one, by the positive
return, of the valve-lever, directly following the lifting thereof in the continued
pull downward on the operating lever as described, the valve is thereby positively
returned to its seat, closing the discharge-pipe.
When the valve is lifted from its seat, opening this discharge-pipe B of the tank
in the second operation of the levers R, U, as described, to raise the valve-lever
and as the lifting of the valve-lever and its valve is directly followed by a release
thereof to their own motion, the return of the valve-lever to its rest and of the
valve to its seat, closing the discharge-pipe, is practically from the entrance of the
water of the tank through the water passage A of the valve into the chamber
thereof, which finally weights it, sufficiently to overcome its floating capacity, or
quality, and thereby to cause it to seat, closing the water-passage of the tank, and
at the same time, bringing the valve-lever to its rest upon the abutment T.
As the water enters into the valve D, as above described, the air therein escapes
through the air-tube L into the discharge-pipe and when the valve is seated, the
water which has entered it, then discharges itself through the water passage H,
into the discharge pipe, rendering the valve capable of another operation, as before.
In lieu of the rigid connection O, between the valve and the valve-lever herein
described, a flexible connection, such as a chain, may be used, in which case, while
the valve-lever, of itself, would be positively and directly returned to its rest after
the first lifting of it and of the valve, the return or seating of the valve as it is a
float-valve, would then be secured either from the weighting of it with water, as
has been described, for its return after the second lifting of the valve, or, from the'

page_text: F
suction of the water running from the tank of the discharge-pipe, should the
valve, in this first instance, be lifted but a short distance, from its seat, fo
the reason hereinafter stated, or from both.
The first lifting of the valve, as described, is for securing a "preliminary wash,
as it is termed, of the water-closet bowl, etc, and the second, for securing an
"after
wash," as it is termed, thereof and the " "preliminary wash" is to be small in
quantity, in comparison with that of the "after wash" and so the levers are
arranged to close the valve after its lift, for the "preliminary wash" and leave the
valve to its own closing, for the "after wash."
The lever mechanism herein described, obviously may be used with valves of
other constructions, and therefore it is not intended to limit said mechanism of
itself, to the particular valve shown, or otherwise, to any of the other features of
this invention shown in connection with it. The discharge pipe B (Figures 1
and 2,) at one side thereof, within the tank, is provided with a horizontal hollow
boss or projection D2 opening, at one end, into said pipe, and at the other end made
with a teat t, opening upward, and into which the overflow and air pipe C is
screwed.
E is a plate placed inside of the hollow boss D³ of the discharge-pipe and
resting upon the bottom wall u, leaving an open space above and between it and
the upper wall v and extending from side to side, of said boss.
w is a stud, or projection, on upper side of plate E', bearing against upper wall
of boss-chamber and having attached to it a stem, or rod, a which passes through
a suitably packed or other water-tight, opening, or bearing, y in the end of the
boss and to the outside thereof, where it is provided with a milled head, or knob z.
The plate, E2, operating it from its knob, can be moved forward in the boss to
project its end portion a³, into and across the water passage of the discharge-
pipe B, so as to reduce the size, or area, of its opening to the size, or area, desired,
and this plate when so projected, partitions, or walls off, and thus closes a portion
of the area of the discharge pipe (Figure 2) to the passage of the water through it,
from the tank, when the valve is opened.
As shown the end a³, of the slide, E³, for projection into the water-passage of
the discharge-pipe is shaped to embrace, or partially, surround the guide-collar M
for the valve-tube B, and which collar, as it is placed, is in line with the movement
of the slide plate E².
This reduction of the size of the water-passage. from the tank, by partitioning,
or walling off, the same, as described, is important, in many ways, as for instance,
for the regulation, or adjustment, of the quantity of water to be delivered to the
bowl, etc, in a given time, to prevent its splashing and spattering about and over
it; and again, when the discharge-pipe below its valve opening, using a float-valve
of a construction, substantially such as described, and the discharge pipe is of a
reduced size, or area, as shown at m³ (Figure 1) from that of said opening, to
obviate the backing up, as it were, of the water around the air-tube L, and thus,
by closing it, at its lower end, to the escape of air from the valve, hinder, or
prevent, the water from entering the valve through the water-passage thereof to
weight it, for it to drop to its seat, as has been described.
The slide-plate-E is simple and, effective, and when once adjusted, it is not
liable to accidental changes or disturbances, and it is all sufficient for the purpose
intended, but other obvious forms of partition might be used, as for instance, a
rotary partition, similar in construction to a damper or regulator etc of stove
pipes etc, and yet secure the same result, and therefore this invention, as to this
feature, is not to be limited to the particular form, or arrangement, of said
partition, herein shown and described, nor to the use of one, or more thereof; the
invention, as to this, consists, in substance, of a partiti n, or wall, in the discharge-
passage leading from the tank, preferably constructed and arranged to be adjusted,
to reduce the size, or area, of the opening of said discharge, as may be desired, to
obtain the results specified.

page_text: The elongated fulcrum-bearing as also the supplementary fulcrum e for the
operating-lever may both be dispensed with, and yet secure the opening and
closing of the valve, substantially as herein described, but it is preferable to employ
thein both, for the reason that with them, increased leverage is given to the
operating-lever to raise the valve-lever from its rest or abutment, and thus to lift
the valve on the return movement of the operating-lever, and the movement of
the arm X of the operating-lever connected with the operating mechanism at the
water-closet etc, is thereby reduced in length.
The regulating-slide for discharge-pipe of water-tank, can be used with other
forms of valves for the discharge-pipe than that particularly shown and described
and with other forms of operating levers for the valves of the discharge-pipes.
In Figures 6 and 7 is shown a modification of the construction of the valve and
operating-levers as to the production of their working and bearing faces d², f, a²,
b2 m n and this modification in view of the description herein before given of such
levers as the same are represented in the preceding Figures, is so apparent on
inspection of said Figures, as to need no particular description.
Again in order that the face b' of the operating lever may pass over the face m
of the valve-lever and to bring its working face a into position for work upon the
working face n of the valve-lever, as has been described the noses c³ and T of the
levers in lieu of being rigid may be, either one or both, hinged as at a³ and butted
against their respective lever and thus hinged, provided with a spring f' to return
them to their abutment after they have been swung by the work of the noses of
the levers against each other in the downward movement of the operating end of
the operating-lever, for permitting of the travel above described of the nose of the
operating-lever across the nose of the valve lever and to the opposite side thereof.
When a hinged nose, or noses, is used, an elongated slotted bearing, either for
the operating-lever or for the valve-lever is not necessary and again, in lieu of
hinging the noses so as to yield they may be otherwise adapted for yielding, as for
instance (Figure 8) by an arrangement of each of them, in a tubular guide, backed
up by a rubber, cushion, or spring band by the head d' of the nose and capable of
a vertical movement, without liability of escape.
In lieu of discharging the contents of the valve directly into the discharge-pipe
of the tank, as has been particularly described, a separate discharge pipe A*
(Figure 6) may be provided therefor, located in suitable position to make connec-
tion with the water discharge of the valve when the valve is closed. And in this
adaptation of the valve for its discharge, it is best to provide the valve with
a projecting tubular passage, as at B', making the discharge of said valve, to enter
said separate discharge A and to make said separate discharge A* such as, when
the valve is opened, to allow of the least possible passage, or waste of water
through it.
This separate discharge A may be, or may not be entered into the regular
discharge passage of the tank.
The passage or escape for air from the valve may be made otherwise than herein
particularly described and shown in the drawing, as for instance, by leading it from
the valve upward instead of downward, and having its upper end open to the
atmosphere above the water level of the tank.
Although this invention has been particularly described in relation to water, its
several features are as applicable to other liquids.
Concerning the mechanism herein described, through which the valve is opened
and allowed to close, it is apparent that the operating lever has a reciprocating
movement, that in the movement of the operating lever, in one direction, it works
by a face d' thereof against a face ƒ of an abutment which is connected to the
valve, and thus the operating lever raises or opeus the valve and after so opening
the valve in the continuation of the movement of the operating lever in the same
direction, the said working face d of said lever escapes from the said working
face f2 of said abutment of the valve and thus leave it, the valve, free to close, and
furthermore, it is apparent that in the movement of the operating lever in the other

page_text: direction said lever works by a face a³ thereof against a face n, of said abutment
and thus the operating lever again raises, or opens, the valve and after so opening
the valve in the continuation of the movement of the operating lever in the same
direction, the said working face a³, of said lever escapes from the said working
face n of said abutment of the valve and thus leaves it, the valve, again free to
close, and brings the working face d' of said lever, which worked against said
working face fƒ of said abutment of the valve in the previous movement of the
lever, and thus lifted the valve as aforesaid, to position for operation to again lift
or open the valve when the operating lever is again moved in the proper direction
therefor.
