page_text: I, ARTHUR LAING, of Deptford Yard, Sunderland, in the County of Durham,
Shipbuilder, do hereby declare the nature of this invention to be as follows:-
My invention relates to ships' water closets and has for its object to so construct
same and dispose the outlet valve that the action of the latter shall be automatic
and efficient, whilst the throwing back of the flush and soil into the pan, should
the storm valve on the ships' side be temporarily open, is obviated and the access
to the vessel of the gases in the discharge pipe effectually prevented.
According to my invention I arrange an outlet valve in the lower part of the
pedestal at the base or side of a chamber or space communicating with a pan with
or without the usual water seal, the said valve may be normally open or adapted to
open outwardly, directly into the discharge pipe or into a second water seal ar-
ranged below the pan and valve and communicating with the discharge pipe.
In such an arrangement I turn the bend of the discharge pipe from the pan
preferably in a curve backwards or forwards, as the discharge may be arranged,
and then downwards towards the base of the pedestal at which part or at the side
of the base of a vertically arranged chamber I mount the outlet valve arranged
to open outwardly in a forward or other direction and it may be arranged to
rest upon its seat in a closed position, normally, or when the outer storm valve
on the ships' side is in such a position as to hang open, or the outlet valve may
hang normally open and communicate direct with the discharge pipe or open into
a water seal arranged in the base of the pedestal forming with the seal in the pan
a double trapped or sealed closet. The lower seal is formed of sufficient depth
about the valve to allow of the easy passage of the soil and flush and its weir or
outer wall is arranged to discharge into the main discharge pipe and above it an
air space or chamber of suitable dimensions may be located and formed by part
of the pedestal.
The operation of a double sealed closet as described is as follows:- -Assuming
that the outlet valve is open or free to open, the soil and flush pass over the weir
of the pan-trap down to and past the valve into the lower water seal the latter
discharging into the main discharge pipe with any soil it may contain, each flush
serving to discharge from the lower seal the soil remaining from the previous flush.
Should water rise in the discharge pipe from the rolling of the vessel the air
pressure in the chamber above the lower water seal increases and acting on the
water therein shuts the outlet valve; should at this time the flushing apparatus
be operated the discharge from the pan is not thrown back therein but is retained
in the space between the valve and the upper part of the weir of the pan which
space may be conveniently made of sufficient dimensions for this purpose. On
decrease of pressure in the discharge pipe the valve opens and allows the soil to
be deposited in the lower seal from which it is removed in the usual course.
The lower water seal in which the valve may be immersed serves as an efficient

page_text: means for preventing the adherence of any soil to the valve the latter oscillating
with the movement of the vessel and being constantly washed by the water.
The valve may in some cases be arranged for operation by suitable levers or
it may be automatic in action as described. Conveniently arranged doors, hand-
holes or other means are provided for removing the valve for cleaning and other
purposes.
The pedestal and pan may be of usual construction apart from the improvements
herein described and of any suitable and usual material and formed in one with
or separately from the valve carrying parts or additional water seal.

I, ARTHUR LAING, of Deptford Yard, Sunderland, in the County of Durham,
Shipbuilder, 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:-
1
My invention relates to ships' water closets and has for its object to so construct
same and dispose the outlet valve that the motion of the latter shall be automatic
and efficient, whilst the throwing back of the flush and soil into the pan, should
the storm valve on the ships' side be temporarily open, is obviated and the access
to the vessel of the gases in the discharge pipe effectually prevented.
According to my invention I arrange an outlet valve in the lower part of the
pedestal at the base or side of a chamber or space communicating with a pan
with or without the usual water seal. The said valve is arranged to rest upon its
seat in a closed position normally or when the outer storm valve on the ships'
side is in such position as to hang open or it may hang normally open and com-
municate with or open into a water seal, arranged below the pan and valve, and
communicating with the discharge pipe leading to the storm valve.
I will describe my invention in reference to the accompanying drawings in
which Figs. 1 and 1^ are elevations of a ships' water closet fitted to a discharge
pipe with the usual storm valve. Fig. 2 is a sectional elevation of water closet
with outlet valve arranged as in Figs. 1 and 1 and Fig. 3 is a similar view of a
water closet with double water seal.
and
Referring to Figs. 1, 14 and 2 the discharge pipe D from the pan A is taken
preferably in a curve as shown, backwards or forwards as the discharge may be
arranged and then downwards towards the base of the pedestal B at which part of
the discharge pipe or at the base of a vertically arranged chamber formed by the
discharge pipe I mount the outlet valve 0 arranged to open outwardly in a
forward or other direction but so that it may rest upon its seat o in a closed
position normally when the outer storm valve S on the ships' side is in
such position as to hang open. This storm valve S is of the usual construction
arranged as shown in the Figures 1, 1 to hang open when the ship assumes a
position by listing as shown in Fig. 1, when the valve O is closed; and when
the ship rolls in the opposite direction the valve S closes and should the movement
of the ship he to a considerable angle the valve opens, but its seat is arranged
at a slight angle as shown, so that during all ordinary movements of the vessel
the valve O will remain closed except when opened by the flush of water.
or
Fig. 3 shows a closet with a double water seal and in this construction the

page_text: valve O which is arranged at the base of a chamber d in a similar manner to
Fig. 2 hangs or may hang normally open and communicates with or opens into
a water seal W1 arranged in the base of the pedestal B forming with the seal W
in the pan a double trapped or sealed closet. The lower seal W₁ is or may be
formed as at w, of sufficient depth about the valve 01 as to allow of the easy
passage of the soil and flush, and its weir or outer wall wol is arranged to discharge
into the main discharge pipe P, and above the weir an air space or chamber C of
suitable dimensions is or may be located and formed by part of the pedestal B.
In the use of outlet valves arranged as described in Figs. 1, 1 and 2 it will be
seen that should the outer storm valve S be open for instance as in Fig. 1* the
water rises in the discharge pipe P but the valve is shut and any noxious gases
in the pipe P cannot be forced by the water pressure into the water closet as
would be the case in ships' closets as ordinarily constructed and arranged where
lever appliances are not employed to close the valves. Moreover should the flush-
ing apparatus be operated whilst the valve is held shut by the pressure of water
in the discharge pipe P the discharge from the pan is not thrown back therein
but is retained in the space d between the valve O and the upper part a of the
weir of the pan A which space d may be conveniently made of sufficient dimensions
for the purpose.. The action of the double sealed closet is similar to that of the
first described arrangement but the valve O¹ hangs normally open but tends to
close when the ship moves in such a position as to open the storm valve S when
should water rise in the discharge pipe P from rolling of the vessel the air
pressure in the chamber C above the lower water seal Wincreases and acting on
the water therein shuts the valve 0¹, on decrease of pressure in the discharge
pipe the valve 01 opens and allows any soil which may be in the chamber d to
be deposited in the lower seal W from which it is removed in the usual course
of flushing. The lower seal WI in which it will be seen the valve 0¹ is immersed
serves, as an efficient means for preventing the adherence of any soil to the
valve 01 the latter oscillating with the movement of the vessel and being constantly
washed by the water.
Conveniently arranged doors or handholes such as H are provided for removing
the valve for cleaning and other purposes. The pedestal B may be of the usual
construction apart from the improvements herein described and of any suitable
and usual material and formed in one with or separately from the valve carrying
parts or the additional water seal.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The combination with and use in ships' water closets of an automatically
operating valve arranged at the base of a chamber or part of the discharge pipe
such as d and adapted to open outwardly therefrom but to be normally closed or
rest upon its seat when the ordinary storm valve on the ships' side is in such
position as to hang open substantially as described.
and
or
2. A ships' water closet with outlet valve constructed and arranged as described
in regard to the closet so as to be normally closed resting upon its seat when
the ordinary storm valve on the ships' side is in such position as to hang open.
3. A ship's water closet with outlet valve arranged as described at the base of
a chamber or part of the discharge pipe forming a chamber which is adapted to
receive and hold the flush and soil from the pan should the said outer valve be
temporarily closed at the time of flushing.
4. The improvements in ships' water closets comprising an outlet valve such
as arranged below the weir of the pan or pan trap and opening into and
adapted to hang normally open and be immersed in a water seal communicating
with the discharge pipe and with or without an air chamber such as C all adapted
to operate substantially in the manner and for the purposes set forth.
