PROVISIONAL SPECIFICATION left by the said William Henry Cutler and
John Chapman at the Office of the Commissioners of Patents on the
30th August 1881.
WILLIAM HENRY CUTLER and JOHN CHAPMAN, both of the Windsor and Eton
Water Works, Eton, in the County of Buckingham. "IMPROVEMENTS IN APPARATUS
FOR PREVENTING THE WASTE OF WATER:"
This Invention has reference to the construction of apparatus for preventing
waste of water when applied to the flushing of water closets, urinals, lavatories,
and other similar purposes, and has for its object the simplification and increased
efficiency of such apparatus, while at the same time the opportunity for tampering
with it is greatly reduced, if not rendered absolutely impossible.
The Invention consists of a small cistern or tank, in which by a suitable partition
or partitions an inner or secondary chamber is formed. This inner chamber com-
municates with the body of the cistern through a flap or other convenient form of
valve attached to the partition, so that while water can flow from the cistern into
the chamber, the return of the water to the cistern is prevented. To the side or
end of the tank, or to both, is fixed, formed, cast, or fashioned a conduit or syphon,
the bend of which is carried above the edge of the cistern or tank. The short leg
of the syphon enters the inner chamber, and reaches to a convenient distance from
the bottom of the cistern, and the long leg, which is suitably contracted at its lower
end, is connected to the pipe leading to the basin of the closet. Fixed directly or
indirectly to the handle of the water closet, or in any other suitable or convenient
position, according to the requirements of the case or the place to be supplied with
water, is an air compressor, or air bellows, or collapsing chamber, furnished with
[Price 6d1

page_text: an inlet valve. To the outlet of this air compressor or bellows is attached a
convenient length of tube to connect it to the inner chamber of the cistern or
tank.
The action of the apparatus is as follows:-A convenient quantity of water is
admitted to the tank or cistern by a ball cock from the ordinary house cistern or
water supply. When it is desired to flush the basin the handle is pulled, and the
air in the bellows is driven through the tube to the top of the inner chamber,
where by reason of the pressure exerted the water contained therein is driven up
the inner leg of the conduit, and causes the syphon to act automatically and draw
off the water contained in the cistern with such rapidity as to effectually flush the
closet. The syphon and pipe are of such capacity that the cistern is emptied and
the action of the syphon ceases before the cistern can obtain a further supply of
water through the smaller supply pipe or ball cock, consequently the quantity of
water to be used at one operation is limited.
A second form consists in making what has herein before been called the inner
chamber exterior to the cistern, the other arrangements connected therewith being
similar.

A third form or modification of the foregoing may be used when desirable.
consists in employing an independent chamber, that may be placed either inside or
outside of the tank or cistern, and made to communicate with the short leg of the
syphon, and in this case the valve before mentioned may be dispensed with.
The tank or cistern and other parts of the apparatus may be made of any suitable
materials, and of such size as is found most convenient.

by the said William Henry Cutler and John Chapman in the Great Seal
Patent Office on the 25th February 1882.
WILLIAM HENRY CUTLER and JOHN CHAPMAN, both of the Windsor and Eton
Water Works, Eton, in the County of Buckingham. "IMPROVEMENTS IN APPARATUS
FOR PREVENTING THE WASTE OF WATER."
This Invention has reference to the construction of apparatus for preventing waste
of water when applied to the flushing of water closets, urinals, lavatories, and other
similar purposes, and has for its object the simplification and increased efficiency of
such apparatus, while at the same time the opportunity for tampering with it is
greatly reduced, if not rendered absolutely impossible.
The Invention consists of a small cistern or tank, in which by a suitable partition
or partitions an inner or secondary chamber is formed. This inner chamber com-
municates with the body of the cistern through a flap or other convenient form of
valve attached to the partition, so that while water can flow from the cistern into
the chamber, the return of the water to the cistern is prevented. To the side or
end of the tank, or to both, is fixed, formed, cast, or fashioned, a conduit or syphon,
the bend of which is carried above the edge of the cistern or tank. The short leg
of the syphon enters the inner chamber, and reaches to a convenient distance from
the bottom of the cistern, and the long leg, which is suitably contracted at its lower
end, is connected to the pipe leading to the basin of the closet. Fixed directly or
indirectly to the handle of the water closet, or any other, suitable or convenient
position, according to the requirements of the case or the place to be supplied
with water, is an air compressor, or air bellows, or collapsing chamber, furnished
with an inlet valve. To the outlet of this air compressor or bellows is attached
a convenient length of tube to connect it to the inner chamber of the cistern or
tank.
In order that the foregoing may be more easily understood Drawings are attached
hereto, of which the following is a description:-Fig. 1 is an elevation of the closet
pan, air compressor, and air tube, and a side sectional elevation of the cistern,
internal chamber, and flushing pipe; Fig. 2 is a side elevation of the cistern and
part of the flushing pipe; Fig. 3 is an end elevation of Fig. 2; Fig. 4 is a plan of
the cistern, chamber, and flushing pipe, and shows the inlet for water with ball
cock and ball attached; Fig. 5 is a side sectional elevation through W,X, of Fig. 4,
with water inlet and ball cock, and Fig. 6 is a section through Y, Z, of Fig. 5, the
inlet pipe and ball cock being removed. Figs. 4, 5, and 6 are drawn to a larger
scale than the previous Figs. In each of the views similar letters refer to the
same parts of the apparatus. A is the cistern with its chamber B and flap valve C;
D is the syphon, the short leg E of which enters the chamber B; F is the long leg
of the syphon, contracted at its lower part, as seen in Fig. 3, and is connected to
the flushing pipe G; H is the seat of the closet, and I the pan; J is the air
compressor, having a valve opening inwards at its bottom. Attached to the bottom
of the compressor is a handle K, which on being drawn up compresses the air in the
said compressor and drives it up the tube L into the chamber B. M is the water
inlet; N, the ball cock, and O, the ball; P, P, are lugs cast on to the cistern for
the purpose of nailing or otherwise securing it to the wall or other support.
The action of the apparatus is as follows:-A convenient quantity of water is
admitted to the tank or cistern A by a ball cock M from the ordinary house cistern
or water supply. When it is desired to flush the basin the handle K is pulled up,
and the air in the compressor or bellows is driven through the tube L to the top of
the inner chamber B, where by reason of the pressure exerted the water contained

page_text: therein is driven up the inner leg E of the conduit, and causes the syphon D to act
automatically and draw off the water contained in the cistern with such rapidity
as to effectually flush the closet.. The syphon D and the pipe G are of such capacity
that the cistern is emptied and the action of the syphon ceases before the cistern
can obtain a further supply of water through the smaller supply pipe or ball cock N,
consequently the quantity of water to be used at one operation is limited.
A second form consists in making what has hereinbefore been called the inner
chamber exterior to the cistern, the other arrangements connected therewith being
similar.
A third form or modification of the foregoing may be used when desirable. It
consists in employing an independent chamber that may be placed either inside or
outside of the tank or cistern, and made to communicate with the short leg of the
syphon, and in this case the valve before mentioned may be dispensed with.
The tank or cistern and other parts of the apparatus may be made of any suitable
materials, and of such size as is found most convenient.
Having now described and particularly set forth the nature of this Invention,
and the manner in which the same is or may be used or carried into effect, we
would observe in conclusion that we do not confine or restrict ourselves to the
precise details or arrangements which we have described or referred to, as variations
may be made therefrom without deviating from the principles or main features
of this Invention, but what we consider to be novel and original, and therefore
claim as the Invention secured to us by the herein before in part recited Letters
Patent is,
Firstly. The construction of the cistern A with its chamber B and syphon D, as
herein described and shown on the Drawings.
Secondly. The construction of the air compressor J furnished with a handle K,
as herein described and shown on the Drawings.
Thirdly. The application of the air tube L leading from the air compressor to the
chamber B, as herein described and shown on the Drawings.
Fourthly. The constructions of the modifications of the apparatus as herein
described.
