Year: 1884

page_text: I, ELIOT HOWARD, of 84, Whitecross Street, Saint Lukes, in the County of
Middlesex, Engineer do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN WATER WASTE PREVENTING APPARATUS FOR WATER CLOSETS,
LAVATORIES AND OTHER APPLIANCES," to be as follows:-
In the specification of Chandler's patent, dated 9th October 1869, N° 2933, is
described the combination of a ball or float cock with a shut off valve or cock in
such a manner that the one works independently of the other with a cistern
without a division. Now the object of this invention is to improve and simplify
the construction of such valve appliances and cisterns. For this purpose I arrange
the seats for the ball valve as well as for the stop valve in one body or casting, and
in such manner that the stop valve closes with the pressure of the water and cuts
off the supply to the ball valve, and so that the stop valve is closed except when
actuated by pressure applied on the end of its spindle or shank. The latter may,
all according to requirements, be placed horizontally or otherwise and the ball
valve may be of any known and suitable form. As applied to the form known as
the Croydon ball valve I arrange the ball valve verticilly and the shut off valve
horizontally above the ball valve and having the end of its spin lle projecting through
a cover and in a line with the inlet opening. Where it passes through the said cover
I provide cup leather or other suitable packing to prevent escape of water. At the
other or inlet end of the valve I provide a helical spring which tends to keep the
valve closed; this spring may be kept in place by a screw plug which also serves
as a strainer. As applied to a water waste preventing cistern I actuate the stop
valve froin some part on or in connection with the weighted lever which also serves
to actuate the outlet and so that the pressure which keeps the shut off valve open
is relieved and the valve closed before the outlet valve is opened thus preventing
waste of water without interfering in any way with the action of the ball valve.
For a so called syphon cistern I by preference arrange a valve of the described form
in such manner that the stop valve is actuated from an arm on the spindle of the
weighted pull lever, which lever actuates an outlet valve that opens into the longer
leg of the syphon, there being a so called lost motion in the action of this outlet
valve so that it cannot open till the inlet has been closed. To improve the action

page_text: of the aforesaid syphon I may employ an outlet valve of the following construction.
The valvo is provided with an upper spindle which passes through a hole in the
bottom of a cylinder or sleeve open at the top where it is connected with the pull
up by a chain or otherwise. The spindle is provided with a piston which works in
the said cylinder and has a cup leather packing, the piston being at the upper end
of the cylinder when in the position of rest. When the cylinder is raised the
water or air contained between the piston and the bottom of the cylinder being
unable to escape freely causes the valve with its piston to rise also; the water or
air then gradually escaping round the spindle or through very small holes provided
in the lower part of the cylinder will enable the valve to drop gradually onto
its seat, thus only allowing the valve to keep open a certain time and a certain
amount only of water to escape even though the pull may be kept up, the amount
of water being so regulated as to start the action of the syphon.

page_text: I, ELIOT HOWARD of 84 Whitecross Street Saint Luke's in the County of
Middlesex Engineer do hereby declare the nature of said Invention for "IMPROVE-
MENTS IN WATER WASTE PREVENTING APPARATUS FOR WATER CLOSETS, LAVATORIES
AND OTHER APPLIANCES and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
"
In the Specification of Chandler's Patent, dated 9th October 1869 N° 2933, is
described the combination of a ball or float cock with a shut off valve or cock in
such a manner that the one works independently of the other with a cistern
without a division. Now the object of this invention is to improve and simplify
the construction of such valve appliances and cisterns. For this purpose I construct
the ball valves or cocks as will be now described with reference to the accompanying
drawings in which Figures 1, 2, 2ª, 3, 4, 5 and 6 show different well known forms
of ball cocks to which this part of my invention is applied.
1 arrange the seats for the ball valve as well as for the stop valve in one body,
fitting, or casting as shown in these figures and in such manner that the stop
valve A closes with the pressure of the water and cuts off the supply to the ball
valve B, and so that the stop valve A is closed except when actuated by pressure
applied on the end of its spindle or shank A. The latter may all according to
requirements be placed horizontally or otherwise and the ball valve may be of any
known and suitable form. As applied to the form known as the Croydon ball
valve Figure 1. I arrange the ball valve B vertically and the shut off valve A
horizontally above the ball valve and having the end A' of its spindle projecting
through a cover C and in a line with the inlet opening D. Where it passes
through the said cover, I provide cup leather E or other suitable packing to prevent
escape of water.
At the other or inlet end D of the valve A I provide a helical
spring F which tends to keep the valve closed; this spring may be kept in place by
a screw plug G which also serves as a strainer.
Figure 2 shows my invention applied to a Croydon pattern ball valve fitted with
a diaphragm E of india rubber, A' being a knob which can be pressed against the
diaphragm E and the end A¹ of the stop valve spindle. Figure 2 is a plan section
on line a. b of Figure 2 showing the water outlets.
Figure 3 shows a Tylor's patent ball cock combined with a stop valve of my
construction. The end A' of the valve spindle is here also actuated by a sliding
knob A².
Figure 4 represents a Lamberts equilibrium pattern ball valve with my invention
applied thereto, the arrangement of the stop valve being as in Figure 2. Instead
of the diaphragm E I may apply the cup leather construction shown in Figure 1.
Figure 5 shows a similar adaptation of Chandler's patent ball valve, and,
Figure 6 shows a similar adaptation of Underbays equilibrium ball valve, from
which figure it will be seen, as an example, that the body may be first made in
two pieces and then fitted together by screwing as shown at S.
As applied to a water waste preventing cistern I actuate the stop valve from
some part on or in connection with the weighted or "cistern lever" which also
serves to actuate the outlet valve from the cistern and so that the pressure which
keeps the shut off valve open is relieved and the valve closed before the outlet
valve is opened thus preventing waste of water without interfering in any way
with the action of the ball valve. For a so-called syphon cistern I by preference
arrange a valve of the described form in such manner, as shown in the vertical
sectional view Figure 7 that the stop valve A is actuated from an arm H on the

page_text: spindle I of the weighted pull lever K.which lever actuates an outlet valve L that
opens into the longer leg M of the syphon, there being a so-called lost motion in
the action of this outlet valve L so that it cannot open till the inlet has been closed.
To improve the action of the aforesaid syphon I may employ any suitable form of
self releasing valve or an outlet valve of the following construction shown in
vertical section Figure 8. This valve N is provided with an upper spindle N¹
which passes through a hole in the bottom of a cylinder or sleeve O open at the
top where it is connected with the pull up by a chain or otherwise The spindle N
is provided with a piston P which works in the said cylinder O and has a cup
leather packing the piston being at the upper end of the cylinder when in tho
position of rest.
When the cylinder O is raised, the water or air, contained between the piston P
and the bottom of the cylinder being unable to escape freely, causes the valve N
with its piston to rise also; the water or air then gradually escaping round the
spindle N or through very small holes provided in the lower part of the cylinder
will enable the valve N to drop gradually on to its seat thus only allowing the
valve to keep open a certain time and a certain amount only of water to escape
even though the pull may be kept up the amount of water being so regulated as to
start the action of the syphon To regulate the escape of the air or water between
the piston P and the bottom of the cylinder a small screw O¹ having a taper groove
may for instance be used. The valve fig 8 as fitted in the cistern is also provided
with a lost motion.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
First The combination of a stop valve and a ball valve in one body, fitting, or
casting in such manner that the stop or inlet valve closes with the water pressure,
cutting off the supply to the ball valve, the inlet valve being kept normally
closed by the water pressure aided if required by a spring substantially as described
and shown.
Second-The application of my combined stop valve and ball valve to syphon
and other water waste preventing cisterns the inlet valve being held open by some
part of the cistern lever, without interference with the ball valve lever, while
the cistern is filling and closing when the cistern lever begins to be pulled, before
the outlet valve opens substantially as described and shown.
Third-The self-releasing cistern outlet valve described with reference to
Figure 8.
Fourth-The arrangement of the syphon cistern substantially as described with
reference to Figures 7 and 8 in which the longer leg of the syphon is fitted with a
lost motion self releasing valve.
