of Water to Water Closets and other Apparatus and Places.
I JAMES RICHARD DAVIES of Holly Walk Luton Beds Brass Founder do
hereby declare the nature of this invention to be as follows:-
It has heretofore been proposed to actuate a valve for the supply of a regulated
quantity of water from constant supply or otherwise by means of a pump actuated
from a pull handle, such valve being connected to a piston or diaphragm against which
liquid pressure from the supply is directed by the action of the pump so as to open the
said valve. Such an arrangement is for instance described with reference to Sheet 3
of the specification of Tylor's expired patent No 685 of 1871. Now this my
invention consists in an improvement upon such previous forms, the main object
being to obtain an after flush as well as a first flush for water closets and the like.
I employ a flushing valve connected to a piston or diaphragm the latter being
larger than the valve so that the pressure from the supply or source keeps the
flushing valve normally shut. In downward continuation of the cylinder for the
aforesaid piston I provide a pump cylinder the partition between the two cylinders
being fitted with a ball or other delivery valve through which the pump piston on
rising can force the water above it and thus raise the valve piston and open the
flushing valve, causing communication between the supply and the passage to the
basin. At the upper part of the pump cylinder is also arranged a ball or other
suction valve which draws water into the pump on the descent of its piston. There
is also a ball or other delivery valve which on the descent of the pump piston
delivers water above the aforesaid partition and against the piston of the flushing
valve thus producing the after flush. This delivery valve is by a lateral passage
in connection with the lower part of the pump cylinder. There is a regulating
passage forming a connection with the passage to the basin and with the upper
ball suction valve for the descent of the pump piston, and also with a lower ball
or other suction valve for the ascent of the piston. The whole thus forms a
double acting pump. The aforesaid regulating passage is provided with a screw or
other means for contracting an opening into the space below the flushing valve
piston more or less as required for regulating the time of flushing or quantity of
water delivered to the basin or other part, and with a screw in the lower part of
the pump cylinder for regulating the down stroke of the piston.

page_text: I also provide a means for regulating the closing of the bottom valve of valve
closets so that the basin and the valve may be more effectually cleansed by the
first flush of water. As at present constructed the valve at the bottom of the
basin is attached to a spindle on one end of which is a cam or tumbler actuated by
a pin on a lever which is raised by the action of the handle so that tbe valve is
opened when the handle is raised and closed immediately the handle is lowered.
Now I propose to continue this spindle a short distance beyond the part
commonly known as the box on the side opposite to the tumbler already mentioned
and to attach to this spindle a second tumbler or cam attached to the piston rod of
a water regulator or pump. This water regulator is supplied with water by a
small pipe from the pipe which conveys water to the basin. The action of this
water regulator is as follows: when the handle of the closet is raised and the
bottom valve is opened, the piston of the regulator will pass freely along the
cylinder, but in its return the escape of the water from one side of the piston to
the other or from the cylinder into the closet will be retarded by the closing of
the valve of the pump or regulator and its motion regulated by means of a screw
as described in the former part of my invention or by a similar device. By this
means the valve at the bottom of the basin is held open after the handle is lowered
and the time that it continues open is regulated by opening or closing the regulating
screw or similar device.

I, JAMES RICHARD DAVIES of Holly Walk, Luton, Beds. Brass Founder do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
It has heretofore been proposed to actuate a valve for the supply of a regulated
quantity of water from constant supply or otherwise by means of a pump actuated
from a pull handle such valve being connected to a piston or diaphragm against
which liquid pressure from the supply is directed by the action of the pump so as
to open the said valve. Such an arrangement is for instance described with
reference to sheet 3 of the specification of Tylors expired patent N° 685 of 1871.
Now this my invention consists in an improvement upon such previous forms, the
main object being to obtain an after flush as well as a first flush for water closets
and the like.
Figure 1 of the accompanying drawings is a vertical section through one form of
my apparatus. I employ a flushing valve B for instance of the form shown; this
valve is connected to a piston F which is larger than the valve B so that the
pressure from the inlet supply K or source keeps the flushing valve B normally
shut. In downward continuation of the cylinder F¹ for the piston F I provide a
pump cylinder A¹ the partition between the two cylinders Fi and A¹ being fitted
with a ball (or other) delivery valve M through which the pump piston A on
rising can force the water above it and thus raise the valve piston F and open the
flushing valve B, causing communication between the supply K and the passage L
to the basin. At the upper part of the pump cylinder A¹ is also arranged a ball
(or other) suction valve G which draws water into the pump on the descent of its
piston A. There is also a ball (or other) delivery valve N which on the descent of
the pump piston A delivers water above the aforesaid partition and against the
piston F of the flushing valve B thus producing the after flush. This delivery
valve N is by a lateral passage Q in connection with the lower part of the pump
cylinder A¹. There is a regulating passage H which forms a connection with the
passage L to the basin and with the upper ball (or other suction valve G for the
descent of the pump piston A and also with the lower ball (or other) suction
valve O for the ascent of the piston. The whole thus forms a double acting pump.
The aforesaid regulating passage H is provided with a screw R, or other means
for contracting an opening into the space below the flushing valve piston F more
or less as required for regulating the time of flushing or quantity of water delivered
to the basin or other part consequent on the ascent of the pump piston A. The
passage H is also provided with a screw P in the lower part of the pump cylinder A¹
for regulating the time of after flush or quantity of water delivered to the basin or
other part consequent on the down stroke of the piston A. At the top of the
apparatus I sometimes provide a set screw T with suitable lock nut or other
appliance to regulate the rise of the valve B as shown in Figures 1. 3. 4. and 5.

page_text: The action is as follows:-When the piston A is raised the valve M and the
water above the piston A passes up through it, thus raising the piston F and lifting
the flushing valve B off its seat and allowing a flush of water from the inlet K to
the outlet L. The valve B descends gradually as the water contained beneath it
escapes through the regulating opening R. When the piston A descends the valve N
opens and admits water from the passage Q to the space above the partition
between the cylinders A¹ and F¹ thus raising the piston F and valve B and giving
the after flush of water from K to L, the valve B descending in the same manner
as before. Water is simultaneously drawn into the pump cylinder above its piston A
through the valve G.
Figure 2 is a vertical sectional part view showing another form of piston F, and
applicable also to the piston A; instead of cupleathers I use in this case a ring S
which on the ascent of the piston rolls down on the piston body and along the
inside of the cylinder, and rolls up similarly on the descent of the piston. The
ring S is of India rubber or other suitable elastic material.
Figure 3 is a vertical sectional view of a water waste preventer similar to figure 1
but having flexible diaphragms A and F instead of pistons.
Figure 4 is a vertical sectional view of a single acting pump arrangement
whereby merely one flushing action is produced, and that in the upstroke of
the piston A which is provided with a valve G for allowing water to pass up
through it during the descent or return stroke of the piston A for filling the space
above it ready for the next up stroke, M is the delivery valve for the up stroke,
and R the screw for regulating the descent of the piston F and flushing valve B.
Figure 5 shows a similar arrangement but with diaphragm F instead of a piston.
I also provide a means for regulating the closing of the bottom valve of valve
closets so that the basin and the valve may be more effectually cleaned by the
first flush of water.
Figure 6 is an end elevation of part of a valve closet fitted with my means or
appliance for the purpose stated. As at present constructed the valve at the
bottom of the basin is attached to a spindle U on one end of which is a cam or
tumbler V actuated by a pin V₁ on a lever V* which is raised by the action of the
handle so that the closet valve is opened when the handle or pull is raised and
closed when the handle is lowered.
Now I propose to continue this spindle U a short distance beyond the part W
usually known as the box on the side opposite to the tumbler V already mentioned
and to fix to this end of the spindle a second tumbler or cam X attached by a pin
to the piston rod X1 of a water regulator or pump Y. This regulator is shown in
vertical sectional elevation in Figure 7, and vertical cross section Figure 8. It is
supplied with water by a small pipe B from the pipe which conveys water to the
basin. The action of this water regulator is as follows:-When the handle of the
closet is raised and the bottom valve of the closet is opened the piston C of
the regulator Y will pass freely along or up its cylinder but on its return or down
stroke the escape of the water from the lower side of the piston to the closet by the
lateral passage E will be retarded (the valve F closing) and its motion is to be
regulated by means of the screw G as described in the former part of my invention
or by a similar device. By this means the valve at the bottom of the basin is held
open after the pull handle is lowered and the time that it continues open is
regulated by the opening or closing more or less of the regulating screw G or
similar device.
Figure 9 is a sectional side elevation of a modified form of regulator where a
valve F is arranged in the piston C, and the passage E provided between the
underside and upper side of the piston C which has a valve F and there is a
screw G for regulating the escape of the water from the upper to the lower side of
the piston during the descent of same. The regulator shown in Figures 7. 8. and 9
is made with a piston and cup leather. It may also be made with a diaphragm as
shown in Figure 3 or with a rolling ring as shown in Figure 2.

page_text: 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:-
FirstThe improved construction of water waste preventer in which the
flushing or supply valve is fitted with a piston or diaphragm which is actuated by
liquid pressure directed by a single or double acting pump the piston or diaphragm
of which is connected to the pull handle, the, parts being arranged and combined
substantially as described with reference to figures 1 to 5 of the accompanying
drawings.
Second-The construction of apparatus for regulating the time of closing the
bottom valve of a closet substantially as described with reference to figures 6 to 9
of the accompanying drawings.
