PROVISIONAL SPECIFICATION.
Improvements in or connected with Water-closets.
1, WILLIAM DUNN, Builder and Decorator, of 26, Albany Street, Regent's Park,
London, do hereby declare the nature of this invention to be as follows:-
My invention has for its object to construct water closets in such a manner, that
they occupy little space and can be hidden from view when not used.
For this purpose the pan and seat are hinged to the upper part of the syphon or
water seal trap by means of a horizontal axle and butt hinge situated immediately
underneath the pan, and the sides of the syphon extend upwards beyond the hinge,
so as to overlap and cover the sides of the
pan.
The back of the syphon is surmounted by an upright flushing basin extending
some distance above the seat and having at the upper end an inlet for the flushing
water. This basin fits into the pan when the latter is turned up into its vertical or
folding position. Provision must be made to support the pan and seat in a
horizontal position, so that they cannot make more than a quarter turn, for instance,
by attaching a projecting arm to the underside of the seat, or to the hinge axle,
which arm comes contact with a stationary hook or detent (fixed to the iron
frame of the closet or to the side of the syphon) when the seat has reached its
horizontal position. The whole apparatus, that is, the syphon (or the upper part of
it) and the flushing basin, is preferably enclosed in a rectangular iron frame fixed
to the wall of the building either in front, or in a recess having the same size and
depth as the iron frame.
The frame may be closed in front by a rectangular cover extending upward from
the hinge axle and hinged either to the same or to a parallel axle. This cover may
be connected with the seat, so that both move together.
The flushing water may be admitted through a tap which is opened by turning the
seat into its upright position against the wall. By the same motion any soil left
in the pan will be discharged into the syphon or towards the back of the basin
which communicates at the bottom with the syphon.
The pan and seat may be made of enamelled metal or other suitable material.

COMPLETE SPECIFICATION.
Improvements in or connected with Water-closets.
I, WILLIAM DUNN, Builder, of 26 Albany Street, Regent's Park, London, N.W.,
do hereby declare the nature of my invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement :-
My invention has for its object to construct water closets in such a manner that
they occupy little space and can be hidden from view when not used.
For this purpose the pan and seat are hinged to the upper part of the syphon or
water seal trap by means of a horizontal axle and butt binge situated immediately
underneath the pan, and the sides of the syphon extend upward beyond the hinge, 50
as to overlap and cover the sides of the pan.
The back of the syphon is surmounted by an upright flushing basin extending
some distance above the seat and having at the upper end an inlet for the flushing
water. This basin fits into the pan when the latter is turned up into its vertical or
folding position.

page_text: In the following description, reference will be made to the accompanying drawings,
in which Fig. 1 is a vertical section of a water closet embodying my invention,
while Figs. 2 and 3 are front views showing the apparatus in different positions.
A is the pan, which is provided with wooden seat B and adapted to turn on a
horizontal axis which nearly coincides with the upper front edge of the syphon or
soil pipe C, thus forming a kind of butt hinge between the latter and the pan.
The hinge axle is formed by a pair of flat iron bars D, provided at the end with
pivots which have their bearings in a rectangular iron frame E fixed to the walls of
the compartment or cupboard which contains the folding closet.
In order to support the pan in its horizontal position, I employ a pair of arms F
attached to the underside of the seat as shown in Fig. 3, and projecting beyond the
hinge axle D in such a manner, as to abut with their ends against the underside of
the rectangular frame mentioned above. As shown in Figs. 2 and 3, the upper part
of the syphon tube C is widened at the sides and has in front an opening into which
fit the projecting sides a of the pan, as shown in Figs. 1 and 3.
H is the flushing basin fixed to back wall of the compartment or recess in a
slightly oblique position. This basin extends down into the syphon pipe and is made
of such a shape and size, as to fit into the pan, when the latter is turned up into its
vertical or folding position, as shown in Fig. 1 by dotted lines. a² are water pockets
formed in the sides of the pan and arranged, in such a manner, that they are filled
with water when the seat is turned up, and discharged when the seat is turned
down. is the flushing pipe which supplies the basin H with water from the
cistern S in the ordinary way.
This cistern is preferably placed in a recess of the wall a suitable distance above
the closet.
The recess or compartment which contains the folding pan is closed at the top by
a board I to which is attached the mechanism for automatically opening the valve of
the flushing cistern, when the seat is turned up. This mechanism comprises a trigger
or lever i which projects below the board I, so as to come in contact with the rim
of the seat (or with a brass plate fixed to the same) when the seat is turned up
into the position shown by Fig. 3; and a pair of bell crank levers J which are
connected with each other and with the flushing valve by wires, and set in motion
by the trigger, when the latter turns on its axis.
bis a handle fixed to the underside of the seat and serving to turn the latter up
or down.
The whole apparatus is preferably placed in a recess or a cupboard let into the
wall of the room, and provided with a pair of doors K, K which are either flush
with the wall or project slightly over the same.
This recess or cupboard may be ventilated by a pipe L which leads out of the room
and perforations in the lower part of the compartment, which admit air from the
room.
Although my invention relates primarily, and chiefly, to water closets, it is evident,
that the hinged pan with flushing arrangement and accessories may be adapted to
serve as urinals or slop sinks.
Having now particularly described and ascertained the nature of my
invention, and in what manner the same is to be performed, I declare, that 1
