PROVISIONAL SPECIFICATION.
Improvements in or connected with Water Closets.
We, THOMAS GARFORTH RHODES, of Albert Terrace, Kirkstall, Leeds, Engineer,
and RAYMOND GAUNT, of The Mount, Stanningley, near Leeds, Engineer, both in
the County of York, do hereby declare the nature of this invention to be as
follows:
Our invention refers to closets of the double siphonic type, in which two water
seals are employed which are divided from each other by an air chamber; and
our object is to ensure the discharge being swift and noiseless on the flushing
cistern being operated, the apparatus for effecting this result being constructed
in a simple and compact form.
According to our invention, we employ an air pipe which is connected to the
air chamber situated between the two water seals, and the said air pipe passes
up through the supply pipe through a suitable aperture in the base of same. The
upper part of the air pipe is provided with an inverted bend, or with a hood, in
such a manner that the passing of water down the supply pipe tends to draw air
from the air pipe. We prefer to pass the air pipe through the base of the supply
pipe by way of a stuffing box, which enables the inverted bend to be passed
through the aperture whilst at the same time the joint of the pipe can be made
perfectly secure.
The basin may suitably be provided with a circular or other bend situated close
up to same, in such a manner that the upper portion of the air chamber is situated
immediately below the end of the air pipe. This enables the air pipe to be
readily fitted to the air space without requiring any bends, and thus enables the
said pipe to be screwed into and out of position with the utmost facility.
In order to minimise the noise at the end of the flush caused by the breaking
of the siphonic action, we make the bottom partition of the closet in a A or
rounded form, thus admitting air gradually to the air chamber at the end of each
flushing operation.

We, THOMAS GARFORTII RHODES, of Albert Terrace, Kirkstall, Leeds, Engineer,
and RAYMOND GAUNT, of The Mount, Stanningley, near Leeds, Engineer, both in
the County of York, 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:―
Our invention refers to closets of the double siphonic type, in which two water

page_text: seals are employed which are divided from each other by an air chamber; and
our object is to ensure the discharge being swift and noiseless on the flushing
cistern being operated, the apparatus for effecting this result being constructed
in a simple and compact form.
In order that our invention may be clearly understood, we will proceed to
describe same with reference to the accompanying 'drawing, in which similar
letters refer to the various parts.
According to our invention, A is the basin which is provided with a circular
bend B, and C is a lead or other bend which is connected by flanges or by other
suitable means, so as to form two water seals D and E as shewn. is an air pipe
which communicates with the air chamber G situated between the two seals D
and E, and the said pipe passes through stuffing boxes B₁ and H into the
supply pipe J communicating with the flushing cistern, up which it rises to a
suitable height and terminates in an inverted bend or hood K. L is the bottom
partition of the basin A, which is made in a A or rounded form, thus admitting
air gradually to the air chamber G at the end of each flushing operation. The
situation of the bend B close up to the basin A, brings the air chamber G
immediately under the supply pipe J, thus enabling the air pipe F to be formed
without bends, and facilitating the adjustment and fitting of the said air pipe
in position; and the large diameter of the stuffing box й enables the hood K
to pass through to facilitate fixing.
On a flush taking place, the water rushes down the supply pipe J to the basin A,
the hood K effectually preventing any water entering the air pipe F; and as the
air is drawn out through the pipe F from the air chamber G the water rises in
the basin A until the head of the water carries the discharge through the two
seals D and E and effects a rapid and practically noiseless flush. The A forma-
tion of the bottom partition then admits air gradually to the air chamber G thus
preventing the noise of a sudden breaking of the flush, and the water returns to
its normal level, the air chamber being in free communication with the interior
of the supply pipe.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
1. The basin A having the bend B in same, connected with a lead or other
bend C, in combination with an air pipe passing from the chamber G up through
the supply pipe J, substantially as and for the purposes set forth.
2. A water closet of the double siphonic type, having an air pipe carrying an
inverted bend or hood on its upper end communicating with the air chamber
situated between the two seals and passing up through the supply pipe, substan-
tially as and for the purposes set forth.
3. In a water closet of the double siphonic type, the air pipe F situated in the
supply pipe J, and passing through stuffing boxes H and B', substantially as and
for the purposes set forth.
4. The combination of the basin A, circular bend B, bend C, seals D and E,
air pipe F, air chamber G, stuffing boxes B' and H, supply pipe J, hood K, and
bottom partition L, substantially as and for the purposes set forth.
