We, GEORGE HENRY JENNINGS and SIDNEY JENNINGS both of Palace Road
Lambeth in the County of Surrey Sanitary Engineers and JoHN MORLEY of 258
Bethnal Green Road in the County of Middlesex, Brass finisher do hereby declare
the nature of our invention for "IMPROVEMENTS IN APPLIANCES AND ARRANGE-
MENTS FOR CONTROLLING REGULATING AND ARRESTING THE SUPPLY OF WATER
to be as follows :-
FOR SANITARY PURPOSES AND PREVENTING WASTE
This Invention has for its object improvements in appliances and arrangements
for controlling regulating and arresting the supply of water for sanitary purposes
and preventing waste.
Our improved appliances and arrangements are applicable especially in those
cases in which a measured quantity of water is required to be delivered in two
separate flows, the first flow being determined by the movement of a lever or
bandie;
and the second or after flow being determined by the release of the said
lover or handle.
We employ a measuring cistern which is divided into two parts by a partition,
the two parts communicate by a passage through the lower part of the partition in
connection with which passage a valve is provided.
In one of the compartments of the cistern a ball valve is fitted for filling the
measuring cistern from a main or from a cistern of larger capacity.
The other compartment of the cistern also has an opening in the bottom provided
with a valve which when lifted permits the water to escape and be delivered from
this compartment into the delivery pipe.
There is a horizontal axis passing through the cistern from side to side at its
upper part and cams or projections on this axis operate the several valves herein-
after mentioned.
The axis has n lever upon it weighted at one end and at the other end a draw
rod is attached. When this rod is pulled downwards the apparatus is set in action
and when it is allowed to return by the action of the weight the second quantity
of water or the after flow is delivered.
⚫When the apparatus is at rest the valve by which one compartment of the cistern
communicates with the other is open.

cistern with the delivery pipe is now opened by its appropriate tappet and the first
flow of water takes place and continues until the lever or handle is released or until
this compartment of the cistern is empty. When the weighted lever and its axis
with the tappits upon it is allowed to return, the valve by which the main flow is
delivered closes. The arrangement to produce the afterflow remains to be described.
For this purpose the compartment of the cistern which receives the supply is
provided with a delivery valve of the following construction.
A dise or valve covers the passage between this compartment of the cistern and
the delivery pipe this is attached to the underside of a collapsible vessel which may
be of india rubber and of a form resembling an accordion. From the top of the
collapsible vessel a rod passes upwards to one of the tappits upon the horizontal
axis. When this axis is rotated for the purpose of setting the apparatus into 1
operation it causes the main-flow to be delivered as already described and it also
pushes down the rod. The valve being already upon its seat the movement causes
the collapsible vessel to be compressed and the water or fluid which it contains is
compelled-to-pass_out_through a valve into another similar vessel serving as a
receiver.

Lambeth in the County of Surrey Sanitary Engineers and JOHN MORLEY of
258 Bethnal Green Road in the County of Middlesex Brassfinisher do hereby
declare the nature of our invention for "IMPROVEMENTS IN APPLIANCES AND
ARRANGEMENTS FOR CONTROLLING REGULATING AND ARRESTING THE SUPPLY OF
and in what manner
WATER FOR SANITARY PURPOSES AND PREVENTING WASTE
the same is to be performed to be particularly described and ascertained in
and by the following statement :-
"
This invention has for its object improvements in appliances and arrangements
for controlling regulating and arresting the supply of water for sanitary purposes
and preventing waste.
Our improved appliances and arrangements are applicable especially in those cases
in which a measured quantity of water is required to be delivered in two separato
flows;
the first flow being determined by the movement of a lever or handle; and
the second or after flow being determined by the release of the said lever or
handle.
We employ a measuring cistern which is divided into two parts by a partition,
the two parts communicate by a passage through the lower part of the partition in
connection with which passage a valve is provided.
In one of the compartments of the cistern a ball valve is fitted for filling the
measuring cistern from a main or from a cistern of larger capacity.
The other compartment of the cistern also has an opening in the bottom provided
with a valve which when lifted permits the water to escape and be delivered from
this compartment into the delivery pipe.
There is a horizontal axis passing through the cistern from side to sido at its
upper part and cams or projections on this axis operate the several valves herein-
after mentioned.
The axis has a lever upon it weighted at one end and to the other end a draw rod
is attached. When this rod is pulled downwards the apparatus is set in action and
when it is allowed to return by the action of the weight the second quantity of
water or the after flow is delivered.
When, the apparatus is at rest the valve by which one compartment of the
cistern communicates with the other is open.
When the axis with the tappits upon it is rotated by the downward pull of the
draw rod it operates to close the valve by which one compartment of the cistern
communicates with the other. The valve connecting the latter compartment of the
cistern with the delivery pipe is now opened by its appropriate tappet and the first
flow of water takes place and continues until the lever or handle is released or
until this compartment of the cistern is empty. When the weighted lover and its
axis with the tappits upon it is allowed to return, the valvo by which the main
flow is delivered closes. The arrangement to produce the after flow remains to be
described. For this purpose the compartment of the cistern which receives the
supply is provided with a delivery valve of the following construction.
A disc or valve covers the passage between this compartment of the cistern and
the delivery pipe, this is attached to the underside of a collapsible vessel which may
be of india rubber and of a form resembling an accordion. From the top of the
collapsible vessel a rod passes upwards to one of the tappits upon the horizontal
axis. When this axis is rotated for the purpose of setting the apparatus into
operation it causes the mainflow to be delivered as already described and it also
pushes down the rod. The valve being already upon its seat the movement causes

page_text: the collapsible vessel to be compressed and the water or fluid which it contains is
compelled to pass out through a valve into another similar vessel serving as a
receiver.
When the first flow of water has been delivered and the axis is allowed to return
the second or after flow results from tho upward movement of the rod to which the
collapsible vessel and valve are attached a movement resulting from the action of
a tappit on the axis. The water or fluid displaced from the collapsible vessel is not
able to return at once when the upward movement of the rod takes place and
as consequently this vessel cannot resume its original dimensions the valve attached
to it is lifted from its seat as the rod moves upward and the water is then
delivered from this compartment of the cistern. After a short time however the
valve returns to its seat the collapsible vessel becoming distended by the return to
it through a small regulated aperture of the water or fluid it originally contained.
In place of the accordion liko vessel of india rubber above described a metal
vessel with a flexible bottom consisting of a disc of india rubber or like material
may be employed.
In order that our said invention may be most fully understood and readily carried
into effect we will proceed to describe the Drawings hereunto annexed.
Figure 1 is a plan-of-an-apparatus.constructed according-to-our-invention..
Figure 2 is a longitudinal section on the line AB in Figure 1
Figure 3 is a transverse section on the line CD in Figure 1.
Figures 4 and 5 are sectional elevations showing especially one of the valves in
two positions.
Figure 6 is a plan of-the-axis-and-tappits by which the valves are operated.
-Figure 7 is an end view of this axis and shows also other parts-in-connection_
therewith.
Figure-8-shows in section an alternative form of delivery valve.
a. a. is a small cistern divided by the partition-a-into-two.compartments. a³ is
a passage by which water is able to pass from one compartment to the other. bis
an ordinary ball valve by which the cistern is filled from a main or other source.―c
is a valve which controls the passage a². d is the delivery valve which first
opens, it is an ordinary lift valve and when raised it permits water to flow from one
compartment of the cistern into the outlet passage and pipe e which is connected
with the pan of a water closet or other place where the water is required. In the
other compartment of the cistern there is another delivery valve which also when
lifted admits water to the outlet c. f. g. and h are three levers mounted within the
cistern a and beneath them the horizontal axis i passes from side to side of the
cistern. The axis i has fixed upon it at its end the weighted lever and to this
lever the draw rod k is connected. When the draw rod is pulled down the axis i
turns partly round and when the draw rod is released the weight causes the axis
to return. The movement in either direction is limited by the weight coming into
contact with the end of the cistern. India rubber pads are provided on the weight
to prevent noise. The valve d is connected with the lever by a rod jointed at its
upper end to the lever. The valve c is similarly connected with the lever and
g
the valve which delivers the afterflow with the lever h.-. and are
corresponding tappits. When the draw rod is pulled down the tappit i³ ceases
to support the lever g and the valve c falls to its seat closing the passage between
the two compartments. Also the tappit raises the lever fand the valve d and
the main flow is discharged. The afterflow is given when the draw rod is released
and the axis returns and this is effected as follows: is a valve disc seating itself
over the aperture by which the afterflow is delivered into the outlet e, it is connected
with the underside of the cylindrical case m by means of the india rubber collapsible
vessel n.
1. are guide stems on the valve disc one entering a socket below the
o is a
valve and the other passing into a socket m¹ in the bottom of the case m.
.

page_text: coiled spring tending to expand the vessel n. This vessel contains water or other
liquid which however is able to pass out by a small valve at the upper end of the
socket m¹ which allows the fluid to pass upwards into the second small collapsiblo
vesssel but prevents its return. The fluid is free to return by an orifice formed by
a groove in the screw p. This groove being wider at the bottom than the top the
orifice can be more or less closed by turning the screw. The second collapsible
vessel within the cylindrical case m serves only to receive the liquid escaping
from the vessel n and to retain it until it returns. q is a screw plug in the cover
of the vessel g, it can be removed to give access to the screw p. When the draw
rod is pulled down the tappit on the axis i presses against the shoulder 1 on
the rod r, it pushes it down overcoming the spring o and collapsing the vessel n
expelling liquid from its interior. When the draw rod is released and the axis
returns the tappit lifts the lever h and the rod which is jointed to this lever.
This movement takes place more rapidly than the vessel n can refill with liquid
returning past the screw p and so regain its forin, hence the valve disc now rises
from its seat and water for the after flow passes from the cistern to the outlet c.
Soon however the vessel n refills, the disc drops to its seat and no more water is
drawn off until the draw rod again moves the axis i. By the use of the second
collapsible vessel 9 the small orifice regulated by the screw p is protected so that it
cannot become stopped by solid matter carried into the cistern with the supply but
this precaution is not always necessary and in such cases the collapsible vessel n
may be allowed to fill from and discharge into the cistern.
The arrangement shown by Figure 8 may also be employed. Here the under
side of the vessel n alone is of india rubber and flexible. The liquid is forced out
through a valve v, into a receiver q* above which may be provided with a cover.
The return is regulated by a stop cock p*.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is-
First An apparatus for delivering a regulated quantity of water in two portions
a flow and an after flow; such apparatus consisting of a divided cistern, each
compartment provided with a delivery valve; the said valves being operated by tho
to and fro movement of an axis or other part the first motion opening the delivery
valve in the compartment froin which the main flow is drawn and the return
motion opening the other delivery valve in the compartment receiving the supply
and from which the after flow is drawn ; the latter delivery valve being so contrived
as automatically to return to its seat after a regulated interval of time substantially
as described.
Second The delivery apparatus herein described consisting of the disc l and the
collapsible vessel n containing liquid and having a narrow outlet passage interposed
between the disc and the stem by which it is actunted substantially as described.
Third The combination in an apparatus for controlling regulating and arresting
the supply of water of any axis with tappits, a collapsible vessel n and a valve
disc substantially as described.
