COMPLETE SPECIFICATION.
Improvements in Water Closets.
We, ROBERT LEWIS, of Custom House Street, Cardiff, House Decorator, and
JOHN JOSEPH NEWMAN, of 111, Cowbridge Road, Cardiff, Plumber, both in the
County of Glamorgan, 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 relates to improvements in water closets and consists in the
combination with the soil pipe and the pan, of a cylinder open by its lower end
to both, and by its opposite end to a flushing cistern, and a piston worked in both
directions in the said cylinder, and adapted to control, according to its position in
the latter, both ends of the cylinder as well as the communication between it and
the pan.
The objects which our invention has in view may be summarised as follows:-
(a.) The abolition of the overhead flushing cistern and its addenda.
(b.) Less noise during the act of flushing.
(c.) Certain flush with less water, as well as other advantages which it is not
necessary to detail here.
In order that the invention and the means by which it is to be carried into
practical effect may be thoroughly understood, we will now describe it and them
in detail, referring in so doing to the accompanying drawing which is to be taken
as part of this Specification and read therewith.
The drawing is a sectional side elevation through the centre of the pan, and
illustrates the application of our invention to the front of the pan. It must be
understood that this relative position is not an essential feature of the invention
and that it may be varied as may be convenient.
a is the pan; b is the casing and c the seat. d is a vertical cylinder. It is
always fixed under the top of, and within, the casing b, and as close to the pan a
as practicable. The drawing shews it as standing in frout of the pan. e is an
opening in that side of the cylinder which is next to the pan. This opening and
the cavity of the pan are placed permanently in communication with each other
by a socket and spigot joint f, which forms the usual outlet from the pan, but to
the cylinder instead of direct to the outlet bend. The side of the pan opposite
to the spigot is concaved towards it so as to facilitate the flush. The cylinder d
is open both at the top and at the bottom. The top of it is connected watertight
with the bottom of a supply cistern h. This stands by the side of the pan the
top of one being about on a level with the top of the other. There is free com-
munication between the cylinder and the cistern through the bottom of the latter.
i is the ball of a ballcock adapted to supply water to the cistern. The bottom of
the cylinder stands upon and is connected to the outlet bend j, e.g., by flanges and
bolts. The bend j is connected to the soil pipe k in the usual way. The diameter
of the bend and soil pipe is preferably less than that of the cylinder d.
I is a piston adapted to work in the cylinder d. It is carried by the bottom end
of the rod m of the pull n. The latter presents itself through the seat cas
heretofore. is a cup leather fixed upon the top of the piston. m³ is a finger on
the rod m adapted to lift the ball i by engaging its stem when the piston / is pulled.
When the piston is down, the communication between the cistern and the pan is
uninterrupted, the water standing at the same height in both.
To empty and flush the pan, the piston is pulled up to the top of its stroke.
This upstroke cuts off the cistern h from the pan, holds up the water in the former,
closes the ballcock either by holding up the water or by the engagement of the
finger m' with the stem of the ball i, opens the communication between the pan and

page_text: the soil pipe, and creates a partial vacuum in the latter. A strong flush is there-
fore established, after which the piston pushed down again. The cistern and
pan are then filled again and the bend j securely sealed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The combination of pan, vertical cylinder open at both ends, direct communi-
cation between the pan and the cylinder, supply cistern opening direct into the
top end of the cylinder, outlet bend or its equivalent connected direct to the
bottom end of the cylinder and piston actuated by a pull presenting itself through
the seat, and adapted to control the communication between the cistern and the
pan and that between the latter and the outlet bend or its equivalent, opening
the one and closing the other according to its terminal position, as set forth.
Dated this 30th day of June 1893.
