Í, JAMES CHANDLER, of 17, Cottage Grove, Mile End Road, in the
County of Middlesex, England, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR DRAWING AND PREVENTING
WASTE OF WATER FROM PIPES, MAINS, OR OTHER SOURCES FOR DOMESTIC OR
OTHER PURPOSES," to be as follows:-
There is already in use an apparatus for the above object constructed
as follows:-A metal cistern divided into two parts, the one part is fitted
and contains an ordinary ball valve which works in the usual way, viz.,
it is connected to the source of supply, and when this division of the
cistern is being emptied the lever and ball falls down and admits the
water and in filling gradually shuts it off. In the lower part of this
division is fitted an ordinary valve, which valve communicates with the
opposite division, and in the said opposite division is fitted another
ordinary valve communicating with the discharge nozzle or outlet from
whence the water is drawn; now these two last-mentioned valves are
connected in such a way that upon giving motion to a lever or beam by

page_text: the hand or other means the valve communicating with the outlet is
opened, and the valve at the lower part of the opposite division closes
(this opposite division being now full of water), and upon letting go the
lever or beam the outlet valve closes, and the valve in the opposite
division opens and allows the water in the same to flow into the said outlet
division. The ball & lever of the first-mentioned valve then falls and
allows the same quantity of water to come in from the source of supply
as was drawn out; the ball valve then closes. Thus it will be understood
that this apparatus consists of one cistern divided into two parts, one
discharge or outlet valve, one communicating valve, and one ordinary
ball valve; and it may be here mentioned that in this apparatus the
discharge division of the cistern must be capable of containing the
maximum quantity of water. The apparatus may be constructed to give
at one operation or draw, while the opposite division of the cistern must
be sufficiently capacious to contain the ball valve. I may also mention
that this said ball valve entirely depends upon its own self-action in
either opening or shutting.
Now my improvements and claims consist as follows:-- A cistern
without a division of the capacity of the maximum quantity of water
the apparatus may be constructed to draw or give at one operation. At the
lower part of this said cistern I place an ordinary valve communicating
with the discharge outlet or nozzle; I also fit in the same cistern a float
valve, and connect it to the source of supply. Now these two valves are
connected together in such a way that by a bell pull or other motion the
ordinary or outlet valve opens, and at the same time and with the same
operation I close the float valve (the cistern being now full of water),
and thus prevent any water coming in while any is being drawn out;
but upon letting go the bell pull or other motion the ordinary or outlet
valve closes, and the float valve is freed, and allows the same quantity of
water to come into the cistern from the source of supply as was drawn
out; the float valve then self-closes. I therefore do with a much smaller
cistern without a division, and one ordinary valve instead of two, and
this ordinary or outlet valve and float valve are so connected that
one must shut before the other opens, and thus prevent the water
running to waste; and this apparatus is capable of discharging the sane
quantity of water as the one first mentioned, and constructed also that
it can be set to discharge whatever quantity of water (below the
maximum) may be required in a given time. I also claim the appli-

page_text: cation of this apparatus & principle to existing cisterns, whatever may
be their size, used for domestic or other purposes. This cistern with
apparatus complete is intended to be fixed more especially in houses over
sinks or drains, streets, roads, courts, & alleys, waterclosets, etc., or
any other place, or be attached to any stand post or pillar or framed
therein.
