We, CHARLES EDGAR WETTON and WILLIAM GALSWORTHY, both of Grims-
bury, in the County of Northampton, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR REGULATING THE SUPPLY OF
LIQUIDS OR FLUIDS," to be as follows:-
The chief object of our Invention is to prevent waste of water in waterclosets
and otherwise, and by our apparatus we are enabled to limit the supply drawn
at any one time.
Our apparatus consists of a casing with a horizontal flexible diaphragm
extending across the middle thereof, of an inlet chamber, of a delivery
chamber, and of pipes and valves, all arranged and acting as hereafter
described. The pipe from the main terminates in two other pipes, one of
which is of small bore and leads to the casing below the diaphragm while the
other leads to the inlet chamber below a weighted valve. The water entering
this chamber raises the valve from its seat, rises in this chamber, and passes
to the delivery chamber; from the delivery chamber a portion of it rises to
the outlet pipe while another portion passes down to the casing above the
diaphragm. A valve rod carried from the middle of the diaphragm where
strengthening plates are fitted is carried up into the delivery chamber and is
fitted with a valve. The small bore pipe is fitted with a two-way cock or
with two cocks, and an exhaust pipe leads therefrom to the outlet from the
delivery chamber.

page_text: The action is as follows:-Supposing the diaphragm is at or near the
bottom of the casing, the casing above the diaphragm will be full of liquid,
and the valve of the delivery chamber will be on its seat as well as the valve
of the inlet chamber; the two-way cock is then turned to admit the liquid
from the main through the small bore pipe into the casing below the diaphragm,
whereby the latter will be raised and lift the valve of the delivery chamber
from its seat; while the diaphragm is rising the liquid will flow through the
inlet chamber, lifting the valve therein, and through the delivery chamber into
the outlet until the valve of the delivery chamber reaches and closes the outlet;
by then reversing the cock the liquid above the diaphragm forces the latter
down and the liquid below it passes out through the exhaust pipe, the flow
from the main into the chambers and through the outlet continuing until the
valve of the delivery chamber reaches its scating, when the other valve falls
upon its seating and the apparatus is ready to again act when the cock is next
turned. The valve of the inlet chamber has the effect of diminishing the
pressure from the main and thereby making the pressure below the diaphragm
greater than that above; instead of this valve any other convenient device
may be adopted to diminish the pressure if necessary, or this inlet chamber
e dispensed with. Instead of the delivery chamber being supplied at the
om and the outlet being at the top the supply may be at the top and the
outlet at the bottom. By dispensing with the two-way cock and the exhaust
pipe, and by fitting a cock to the outlet, and a valve opening upwards in the
diaphragm, which in this case would be weighted, the effects herein-before
described would be obtained; the liquid as the diaphragm again descended
would pass through the valve of the diaphragm instead of through the exhaust
pipe. By either removing the valve seating of the delivery chamber or by
fitting the valve so that it cannot close the outlet the apparatus may be
employed as a cock.
