Middlesex Engineer for an Invention of "IMPROVED MEANS FOR WORKING
1655 BAD SANIMADV AND
ATHED
BUDDASE"
PROVISIONAL SPECIFICATION left by the said William George Stuart at
the Office of the Commissioners of Patents on the 9th September 1882.
WILLIAM GEORGE STUART of 35 Western Road Wood Green Middlesex Engineer
"IMPROVED MEANS FOR WORKING VALVES FOR SANITARY AND OTHER PURPOSES
"
My invention relates to the introduction of a new apparatus for the opening or
closing of valves used for sanitary and other purposes whereby such valves can be
worked through the medium of a double action air or liquid pump.
The invention consists in the application of any form of pump as a means of
actuating valves for sanitary and other purposes and is effected by the introduction
of a piston or diaphragm on to the valve spindle required to be moved. By means
of said pump exerting pressure or vacuum upon this piston or diaphragm the valve
is forced to rest upon its seat or is drawn from its seat and so opened or closed
at will.

"IMPROVED MEANS FOR WORKING VALVES FOR SANITARY AND OTHER PURPOSES
"
My Invention relates to the introduction of a new apparatus for the opening or
closing of valves used for sanitary and other purposes whereby such valves can be
worked through the medium of a double action air or liquid pump.
The Invention consists in the application of any form of pump as a means of
actuating valves for sanitary and other purposes and is effected by the introduction
of a piston or diaphragm on to the valve spindle required to be moved. By means
of said pump exerting pressure or vacuum upon this piston or diaphragm the valve
is forced to rest upon its seat or is drawn from its seat and so closed or opened
at will.
And in order that my said Invention may be well understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the
accompanying sheet of drawings like letters of reference indicating corresponding
parts in the respective figures
Figure 1 is a vertical section of one form of my invention and figure 2 a section
on line 1. 2. in figure 1.
A represents the valve to be opened or closed and contained with its seat in the
valve box B. which communicates with the main through inlet passage C. and with
the water closet basin or other apparatus to be flushed or supplied with water, by
the pipe or passage D.-The spindle of the valve A is fitted at its upper end with
a diaphragm (or piston) E. of India rubber, leather or other flexible material and is
provided with a spring F. for returning the valve A to its seat as hereafter more
particularly referred to.-Above the diaphragm (or piston) E is a pipe or passage G
communicating with the upper or delivery chamber of any suitable description of
pump, but preferably of a double acting combined plunger and bucket pump H. the
plunger portion of which above the delivery valve I of the bucket is made hollow
so as to constitute an air vessel.-J is the suction valve of the pump H which
communicates with and draws from the chamber K of the valve box B by the pipe
or passage J.-The pump H is worked by a lever or handle L. which is provided
with a counterbalance weight (not shewn) for normally keeping the pump H at its
bottom stroke-In the valve box B. between the chamber K and the space above
the diaphragm (or piston) E of the valve A is a small pipe or passage M (see
figure 2) the flow through which from the said space is regulated by a cock N
(valve or other device)
On its being required to open the valve A the plunger bucket of the pump H is
raised by its lever or bandle L whereby the water contained in the pump H above
the valve I acts upon the upper side of the diaphragm (or piston) E. and pressing
down the latter carries with it the spindle of the valve A and thereby forces the latter
away from its seat or opens it so as to admit the water coming from the inain
through inlet passage C. into the chamber K of the valve box B. and through pipe
or passage D. to the water closet basin or other apparatus to be flushed or supplied
On letting go or lowering the lever or handle L. the pressure is renewed on the

page_text: diaphragm (or piston) E. by the passage of the water through the delivery valve I
of the bucket into the delivery chamber and hollow plunger or air vessel of the
pump H when the cock N. (being previously set so as to regulate the time for
which the valve A is to remain open) allows the water above the diaphragm (or
piston) E. to escape through the pipe or passage M. into the chamber. K. of the valve
box B. This causes the pressure to be gradually taken off the diaphragm E. until
the valve A is closed by the combined action of the spring F. and pressure from the
main-If on the other hand instead of immediately letting go the handle L as
described it is allowed to remain raised the same effect will be produced on the
diaphragm E. and the valve A. will be closed by the escape of the water through
pipe M into the chamber K the operation of opening and closing the valve A being
afterwards repeated on letting go or lowering the handle L by the double action
of the pump H, thus causing an after flush to the closet
If desired the action of the valve A may be reversed in which case the pipe or
passage M instead of communicating with the chamber K will be connected with
the main, and the pump H will be arranged in its upstroke to draw from or cause
a vacuum above the diaphragm (or piston) E. whereby the valve A. will be opened
on raising the handle L. and closed again as soon as the vacuum is destroyed and a
superior pressure induced on the diaphragm (or piston) E. by the water coming
from the main through pipe or passage M
In figure la the spindle of the valve A and diaphragm (or piston) E. is shewn
continued outwards through a stuffing box in the top cover of the space above the
diaphragm E. (in lieu of closing this space by a plug as in figure 1) where it may
be connected with any suitable form of registering device
Figure 3. shews the application of my double acting hollow plunger pump H
(partly broken away) to feeding steam boilers
Figure 4. is a vertical section and figure 5 a plan of a modified arrangement of
my invention in which the pump H'. is single acting, a valve 0 being placed
between its upper or delivery chamber and the diaphragm (or piston) E. for the
purpose of confining the water between the pump H and the diaphragm E. by
which means there is no return of water to the pump H' on letting go the handle L
and a certain quantity of water must pass through the passage M into the
chamber K and closet basin before the valve A can close.
This form of my invention may be advantageously used for street (or house)
purposes (see figure 6) in which case the valve O should be dispensed with so that
on raising the handle L any desired quantity of water may be drawn off for use
and the handle L being then allowed to drop the valve A will be closed
immediately and any further escape of water prevented
The advantages of my invention are that by the use of a double acting pump,
preferably having a hollow plunger acting as an air vessel the valve to the closet
or other purpose is kept open as long as required by the regulating cock N which
is not the case with the ordinary method of working this class of valve-Also in
consequence of the water closet being flushed on raising the lever or handle of the
pump and again after flushed by letting the handle go a certain quantity of water
only is retained in the basin or pan thereby preventing the waste of water so
common under the ordinary system when the lever or handle is left raised after
flushing and allows a continual escape of water
Having now described and particularly ascertained the nature of my said
invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider novel and original and
therefore claim as my invention is
The combination and use with the valve (or valves) used for sanitary and other
purposes and constructed with a diaphragm (or piston), of a double or single acting
air or liquid pump (preferably of a double acting combined hollow plunger and

page_text: bucket pump) and of a regulating pipe or passage substantially as and for the
purposes herein before described and illustrated by the accompanying drawing
In witness whereof I the said William George Stuart have hereunto set my
hand and seal this 22nd day of February in the year of Our Lord One
thousand eight hundred and eighty three
