Wo GEORGE HENRY JENNINGS and SIDNEY JENNINGS both of Palace Road'
Lambeth in the County of Surrey Sanitary Engineers do hereby declare the naturo
of our invention for "IMPROVEMENTS IN APPLIANCES AND ARRANGEMENTS. FOR
CONTROLLING REGULATING AND ARRESTING THE SUPPLY OF WATER FOR SANITARY
PURPOSES AND PREVENTING WASTE" to be as follows:-
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.
We employ for these purposes a small cistern containing the measure of water
which it is desired to draw off at one tiine; this cistern is supplied from a main or
from a larger cistern by means of a ball valve and it is provided with an overflow
pipe.
Within the cistern a siphon is fixed with its mouth near the bottom of the
cistern and the bend in which there is a small air vent above the water level
therein.
This siphon is connected through the bottom of the cistern with the pipe or
passage by which it is intended the water should be delivered. There is also
another passage connected with the descending pipe immediately beneath the
bottom of the cistern it opens into the cistern by an aperture provided with a valve
of large area and this valve is connected by a rod with a lifting lever.
Beneath the lifting lever and the lever of the ball valve we arrango a horizontal
axis passing through the cistern from side to side.
Outside the cistern the axis has a lever mounted upon it; one end of this lever
carries a weight and at the other end there is connected a descending rod to which
novement is transmitted in any convenient way when it is required that the
measured quantity of water should be drawn off.
When this rod is drawn down by means of a lever handle or any convenient
onnection the weight at the other end of the lever is raised, and the horizontal
xis is caused to make a partial rotation.

page_text: This movement of the axis brings a block which is fixed upon it beneath the
ball lever in such a position that the said lever cannot descend until the axis has
returned to its original position. Hence whilst the weighted end of the lever is
raised water cannot enter the measuring cistern.
The same movement of the horizontal axis also brings a tappet beneath tho
lifting lever already referred to, and forces this upwards thereby lifting the large
valve at the bottom of the measuring cistern. Water then rushes from the cistern
down the delivery pipe and this flow of water brings the siphon into operation, so
that although the valve may be closed when only a comparatively small quantity
of water has passed out of the cistern, nevertheless the measured quantity of water
will be delivered as the siphon will continue the flow until the measuring cistern is
empty.
The draw rod which is connected with the end of the weighted lever we
construct in such manner that its length may be adjusted.
The upper portion of the rod receives at its lower end a stirrup which is free to
turn upon it, and through the bottom of this stirrup a screw stem passes. The
stem has an oye at its lower end for the connection of a draw wire or other
attachment, and it also has a lock nut upon it.
-The adjustment is effected by turning the stirrup in one direction or the other
according as an increase or decrease of length is required.
When the proper adjustment has been made the lock nut is screwed up until it
bears against the under side of the stirrup.
The measuring cistern is supported upon brackets fixed against the wall. A peg
projects up from each bracket, and this passes through a hole in a lug cast upon
-the cistern, upon the side next to the wall.
Each bracket also at its outer end is perforated and a corresponding projection
cast upon the under side of the cistern enters the perforation. The connection of
the delivery pipe renders the cistern immoveable upon the brackets.

page_text: WC, GEORGE HENRY JENNINGS and SIDNEY JENNINGS both of Palace Road
Lambeth in the County of Surrey Sanitary Engineers do hereby declaro the naturo
of our invention for "IMPROVEMENTS IN APPLIANCES AND ARRANGEMENTS FOR
CONTROLLING, REGULATING AND ARRESTING THE SUPPLY OF WATER FOR SANITARY
PURPOSES AND PREVENTING WASTE" and in what manner 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.
We employ for these purposes a small cistern containing the measure of water
which it is desired to draw off at one time, this cistern is supplied from a main or
from a larger cistern by means of a ball valve, and it is provided with an overflow
pipe.
Within the cistern a siphon is fixed with its mouth near the bottom of the
cistern and the bend in which there is a small air vent above the water level
therein.
This siphon is connected through the bottom of the cistern with the pipe or
passage by which it is intended the water should be delivered. There is also
another passage connected with the descending pipe immediately beneath the
bottom of the cistern, it opens into the cistern by an aperture provided with a valve
of large area, and this valve is connected by a rod with a lifting lever.
Beneath the lifting lever and the lever of the ball valve we arrange a horizontal
axis passing through the cistern from side to side.
Outside the cistern the axis has a lever mounted upon it; one end of this lever
carries a weight and at the other end there is connected a descending rod to which
movement is transmitted in any convenient way when it is required that the
measured quantity of water should be drawn off.
When this rod is drawn down by means of a lever handle or any convenient
connection the weight at the other end of the lever is raised, and the horizontal
axis is caused to make a partial rotation.
This movement of the axis brings a block which is fixed upon it beneath the
ball lever in such a position that the said lever cannot descend until the axis has
returned to its original position. Hence whilst the weighted end of the lever is
raised water cannot enter the measuring cistern.
The saine movement of the horizontal axis also brings a tappet beneath the
lifting lever already referred to, and forces this upwards thereby lifting the large
valve at the bottom of the measuring cistern. Water then rushes from the cistern
down the delivery pipe, and this flow of water brings the siphon into operation, so.
that although the valve may be closed when only a comparatively small quantity
of water has pa-sed out of the cistern, nevertheless the measured quantity of water
will be delivered as the siphon will continue the flow until the measuring cistern is
empty.
The draw rod which is connected with the end of the weighted lever we
construct in such manner that its length may be adjusted.
The upper portion of the rod receives at its lower end a stirrup which is free to
turn upon it, and through the bottom of this stirrup a screw stem passes. The
stem has an eye at its lower end for the connection of a draw wire or other
attachment, and it also has a lock nut upon it.

page_text: The adjustment is effected by turning the stirrup in one direction or the other
according as an increase or decrease of length is required.
When the proper adjustment has been inade the lock nut is screwed up until it
bears against the under side of the stirrup.
The measuring cistern is supported upon brackets fixed against the wall. A peg
projects up from each bracket, and this passes through a hole in a lug cast upon
the cistern, upon the side next to the wall.
Each bracket also at its outer end is perforated and a corresponding projection
cast upon the under side of the cistern enters the perforation. The connection of
the delivery pipe renders the cistern immoveable upon the brackets.
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.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section and Figure 2 is a transverse section of an
appliance or arrangement of apparatus in accordance with our invention.
Figure 3 is a side clevation and Figure 4 is a plan of one of a pair of brackets on
which the apparatus is supported.
a is a cistern of a capacity to contain the quantity of water which it is intended
shall be drawn off at each action of the apparatus.
b, is a valve by which the entrance of water to the cistern from a main or
otherwise is controlled.
c is a ball float at the end of a lever o¹ which in the usual way closes the valve
up to its seat when the cistern is full.
d is the delivery passage it communicates with-the interior of the cistern by two
openings in its bottom, over one of these openings the siphon e is fixed. The bend
of the siphon is above the level to which the water rises in the cistern and there is
a small vent hole in it at e¹.
The other hole in the hottom of the cistern a is guarded by a valve ƒ. A rod ƒ¹
connects the valve f with a lever g having its fulcrum at g¹.
An axis h passes through the cistern by holes in the sides above the water level,
and i, is a weighted lever fixed on the end of the axis outside the cistern. The
weight tends to keep the lever in the position in which it is indicated by the full
lines, the side of the cistern serves to limit its movement. ¹are pieces of india
rubber let into the weight these come against the cistern and the lever is stopped
without noise.
j is an overflow. k is a draw rod which is pulled down when the delivery of the
measured quantity of water is required to take place; this may be effected by a
connection of the usual sort with the handle when the water is required for the
service of a water closet.
The connection with the draw rod is made by means of a wire chain or cord
attached to the eye k'. This eye is at the end of a stem k which screws into the
bottom of the stirrup k³. By turning the stirrup upon the rod and stem after all
the connections have been made the effective length of the rod can be adjusted.
is a lock nut on the stem k³ by which it is secured when the adjustment bas
been made.
The axis h has two enlargements upon it, one of these h¹ when the axis is turned
by drawing down the rod immediately passes underneath the lever c¹ and
supports it so that the valve b cannot open until the axis returns to its original
position.
The other enlargement ³ on the axis h is beneath the lever g and in the
novenient of the axis it operates as a tappet to lift this lever immediately after the
lever c¹ has been blocked by h¹. When the valve f is thus raised the water from
the cistern rushes down the delivery passage d.
The fall of water in the delivery pipe produces a partial vacuum in the siphon
and water from the cistern then passes over the bend.
