PROVISIONAL SPECIFICATION.
Improved Apparatus for Preventing Waste of Water in or from
Cisterns.
I ROBERT THOMAS SPRING of 87 Newland in the Town and County of
Northampton Foreman of Waterworks do hereby declare the nature of this inven-
tion to be as follows:-
For the purpose of preventing waste of water from water closet or like cisterns I
fit such cisterns with a simple syphoning apparatus constructed after the following
manner.
In one corner of the cistern or in other convenient position I arrange a cover or
bell under which and in the bottom of the cistern is secured the outlet pipe on the
end of which I mount or attach a hollow inverted cone or funnel of sufficient height
to a short distance say about 1 inches or thereabouts above the normal level of the
water when cistern contains the intended quantity.
In place of the usual ball-cock apparatus I make the arm or rod carrying the
ball of sufficient length to reach almost to the opposite end or side of the cistern
and on the end I secure instead of the usual ball a hollow air-tight vessel of
sufficient capacity to displace when depressed as hereafter described as much water
as may be necessary for one flush of the closet and to raise the level of the water to
a point above the mouth of the cone or funnel. To the rear and at the top of the
hollow vessel I attach a short arm or rod projecting beyond and over the end or
side of the cistern and from the extremity thereof I hang a chain, rope, wire or the
like terminating in a loop or handle. When the chain or the like is pulled the air
tight vessel is forced down so displacing a quantity of water and causing it to rise
in the cistern over the mouth of the cone or funnel (which is also the overflow)
under the bell an orifice being provided at the bottom of the said bell for inflow of
water, thus starting the syphon and at same time opening the tap or cock and
allowing entrance of water from supply pipe.
On releasing the chain the air tight vessel rises to normal position floating on
surface, the supply is gradually cut off and the syphon ceases to act.
No valves of any kind are required and the only moveable part of the apparatus
is the air tight vessel, rod pull down device, and supply cock.
The action is noiseless.

Improved Apparatus for Preventing Waste of Water in or from
Cisterns.
I ROBERT THOMAS SPRING of Stimpson Street & late of 87 Newland in the
Town and County of Northampton Foreman of Waterworks 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 :-
For the purpose of preventing waste of water from water closet or like cisterns I
fit such cisterns with a simple syphoning aparatus constructed after the following
manner

page_text: C
In one corner of the cistern or in other convenient position I arrange a cover or
bell (c) under which and in the bottom of the cistern is secured the outlet pipe on
the end of which I mount or attach a hollow inverted cone or funnel (d) of sufficient
height to a short distance, say about 14 inches or thereabouts above the normal
level of the water when cistern contains the intended quantity.
In place of the usual ball cock aparatus I make the arm or rod (a) carrying the
ball (b) of sufficient length to reach almost to the opposite end or side of the cistern
and on the end I secure instead of the usual ball a hollow air-tight vessel of sufficient
capacity to displace when depressed, as hereinafter described as much water as may
be necessary for one flush of the closet and to raise the level of the water to a point
above the mouth of the cone or funnel (d). To the rear and at the top of the
hollow vessel I attach a short arm or rod projecting beyond and over the end or
side of the cistern and from the extremity thereof I hang a chain, rope, wire, or the
like terminating in a loop or handle.
When the chain or the like is pulled the air-tight vessel is forced down so
displacing a quantity of water and causing it to rise in the cistern over the mouth
of the cone or funnel (d) (which is also the overflow) under the bell (c) an orifice
being provided at the bottom of the said bell for inflow of water thus starting the
syphon and at same time opening the tap or cock and allowing entrance of water
from supply pipe.
On releasing the chain the air tight vessel rises to normal position floating on
surface the supply is gradually cut off and the syphon ceases to act.
No valves of any kind are required and the only moveable part of the aparatus
is the air tight vessel, rod, pull down device and supply cock.
The action is noiseless.
The hollow air tight vessel (b) is fitted near the bottom and passing from side to
side, with a projection or fin to prevent the vessel splashing the water over side of
cistern.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The improved outlet inverted cone or funnel.
2. The loose cover or bell of the improved outlet inverted cone or funnel.
3. The air tight vessel attached to the ball cock and fitted with fin to prevent
splashing.
