I, PETER CHARLES, of Church Street, Stoke Newington, in the County
5 of Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR SUPPLYING WATER TO WATERCLOSETS, AND FOR.
THE PREVENTION OF WASTE OF WATER ADMITTED THERETO," to be as follows:-
This Invention has for its object the regulation of the supply and
prevention of waste of water admitted to waterclosets, and consists in
the construction and application of apparatus of which the following is.
a description :—
A cistern, made by preference of cast iron, though not limited thereto,
as any suitable material may be used, is divided by partitions into three
compartments, one of which is of considerably larger dimensions than

page_text: the others.
Into this larger compartment, which may be called the
supply chamber, water is admitted by a pipe in connection with the
service where a constant supply is established, or the ordinary house
cistern where an intermediate supply only is afforded, and to which is
attached a ball valve, so that when the water reaches a certain height
the further admission is shut off. Communications are made between
the large compartment and the two smaller chambers by means of two
short conduits, each furnished with a valve, those commonly known as
spindle valves being preferred. Each of the small chambers has an
opening in or near the bottom to which a pipe is attached, and is so
arranged that these pipes may be connected together and form one
common outlet. Across the top of the cistern in any convenient direc-
tion a shaft having arms or cranks is mounted and works in bearings
formend on the edges of the cistern. Each of the spindle valves is
connected to one of the cranks or arms above it by a rod or chain, and
to one of the cranks or arms a weight is attached, so that when the
apparatus is at rest the position of the valves may always assume the
same relation to each other.
The action of the apparatus is as follows:-Water being admitted to
the large compartment it flows through one of the valves into one of
the smaller chambers until it attains the same level, when the ball valve
shuts off any further addition. When the closet is to be flushed a cord,
chain, or lever is made to operate upon the shaft before mentioned and
raise the outlet valve, while the inlet valve by its own gravity sinks into
its seat and prevents more water issuing from the supply chamber. A
regulated quantity is thus conveyed to the closet pan at each flushing.
Simultaneously with the action just described water is being admitted
to the other small chamber through its own inlet valve until it
has risen to the same level as that in the supply chamber, when
on the release of the cord, chain, or lever to which the hand has
been applied, the inlet valve of the second small chamber is closed
and the outlet valve opened, thereby allowing the water to flow to the
pan in suitable quantity to fit it for future use when the operation will
he repeated.

at each flushing, and that by its employment the future user of the
closet is not deprived of that desirable supply of water to the pan so
necessary to constitute an efficient watercloset.
