page_text: I, JOHN SHAW HELYER, of Bryn y Coed, Woodside Road, Woolston, South-
ampton, Naval Architect, do hereby declare the nature of this invention to be as
follows:-
The type of water-closet or pan to which this invention relates is that which is
placed below the water line or level in boats, and ships, and requires the contents
or soil to be forced out by a pump action, and the object of the invention is
to provide a light, inexpensive, and simple apparatus that will not readily get
out of order, and whereby soil, slops, and other liquids can be discharged from
below water-line on boats and ships.
According to my invention the pan or basin of the closet itself is adapted to be
used as a pump to discharge the soil, slops, or other liquid into the superimposing
water, and it consists practically of an ordinary pump turned upside down, and
adapted so as the then top can be used as a closet pan, this pan part is also used,
(with or without suitable handles) by being drawn up and down, to force its
contents into the superimposing water, and the valves of the closet being seated
on the underside of each hole of the valve box, prevent anything returning.
In the carrying out of my invention, the pan or basin of the closet is mounted
on a chamber, or valve box, and has an extended part adapted to enter said
chamber, or the lower part of the pan is adapted to enter the chamber, a suitable
packing being provided between the inner surface of the chamber, and the outer
surface of the pan, or the extended part so as to make joint therein, and when the
pan is drawn up, or forced down in the chamber. From the lower part of the
chamber or valve box extends a discharge pipe, which leads through the ships
side and outboard. In the valve box under the pan there is provided a ball or other
suitable valve, and in the discharge pipe, and under the discharge opening of the
chamber there is a ball or other suitable valve, both these valves open downwards,
and are made of light material, and adapted to float to their seats, or be returned
to their seats by springs or equivelant devices.
To force out the contents or soil which is in the pan it is drawn up by hand
until the soil or other contents passes the valve, and flows into the chamber, and
upon the pan being then forced down the valve closes the opening between the
chamber and the pan, and the contents are forced past the valve in the discharge
pipe and through the discharge pipe outboard against the superimposing water.

Improved Under-water-line Water Closet.
I, JOHN SHAW HELYER, of Bryn-y-Coed, Woodside Road, Woolston, South-
ampton, Naval Architect, do hereby declare the nature of this invention, and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:--
The type of water-closet or pan to which this invention relates is that which is
placed below the water line or level in boats and ships, and requires the contents
or soil to be forced out by a pump action, and the object of this invention is
to provide a light, inexpensive and simple apparatus that will not readily get
out of order, and whereby soil, slops, and other liquids can be discharged from
below water-line on boats and ships.
According to my invention the pan or basin of the closet itself is adapted to be
used as a pump to discharge the soil, slops, or other liquid into the superimposing
water, and it consists practically of an ordinary pump turned upside down, and
adapted so as the then top can be used as a closet pan, this pan part is also used,
(with or without suitable handles) by being drawn up and down to force its
contents into the superimposing water, and the valves of the closet being seated
on the underside of each hole of the valve box prevent anything returning.
In the carrying out of my invention the pan or basin of the closet is mounted
on a chamber, or valve box, and has an extended part adapted to enter said
chamber, or the lower part of the pan is adapted to enter the chamber, a suitable
packing being provided between the inner surface of the chamber, and the outer
surface of the pan, or the extended part so as to make joint therein, and when the
pan is drawn up or forced down in the chamber. From the lower part of the
chamber or valve box extends a discharge pipe which leads through the ships
side and outboard. In the valve box under the pan there is provided a ball or other
suitable valve, and in the discharge pipe and under the discharge opening of the
chamber there is a ball or other suitable valve, both these valves open downwards,
and are made of light material and adapted to float to their seats, or be returned
to their seats by springs or equivelant devices.
To force out the contents or soil which is in the pan it is drawn up by hand
until the soil or other contents passes the valve and flows into the chamber, and
upon the pan being then forced down the valve closes the opening between the
chamber and the pan, and the contents are forced past the valve in the discharge
pine and through the discharge pipe outboard against the superimposing water.
Having thus generally described the object, nature and effects of my invention
J will now proceed to describe it with reference to the accompanying sheet of
drawings. The example of apparatus which I have illustrated is a below water-
line water-closet with floatable ball valves. In the drawings the same parts are
designated by the same letters of reference, and they correspond with those used
in the following explanation.
Figure 1 is a sectional elevation of my improved water closet showing the
closet pan in its normal position, and
Figure 2 a like section showing the pan drawn up in the act of discharging.
With reference to the drawings a designates the pan of the closet and b the
flushing pipe. The pan is mounted on a chamber by means of an extension
or bell pipe d which telescopes into the chamber so that the pan is free to be
drawn up, and forced down by hand by the rim a¹, the part d working in the
chamber which is provided with a stuffing box and packing e to make joint
between the working surfaces. From the underside of the chamber c extends a
discharge chamber having a discharge pipe leading to the ships side and out-
Hoard. The bottom of the pan a is open and constructed to form a seat for a
floatable ball valve h contained in the extension pipe d, and the bottom of the
chamber c is provided with an opening and constructed to form a seat for a float-

page_text: able ball valve i contained in the discharge-chamber-f-both these valves hand i
open downwards and are preferably made of material such as india-rubber and are
adapted to float to their seats as illustrated in the drawings, in the chamber f
under the ball valve i there are provided two wires or arms k which act as rests
for the ball i when the nan a is being discharged and keep the ball in a position
from which it readily floats to its seat on the return action of the pan a.
The chamber is provided with a flange c by which the closet is fixed on the
floors. and a suitable stop is provided to prevent the pan pipe d being accidently
lifted out of the chamber c.
It will be seen that my improved closet is practically a simple pump inverted.
with two boyant valves hand i. To force out the contents or soil in the pan
the wooden seat which is of the usual form, mounted on hinges, is raised, then
the nan a is drawn up by hand by means of its rim : the flushing pipe b having a
flexable pipe connection to allow of this action, until the soil or contents passes the
valve h into the chamber c and the extended part d as shown in Figure 2 of the
drawings, upon the pan a being forced down the valve h closes the bottom
of the pan a and the contents of the chamber c are forced past the
valve i and through the discharge chamber f and pipe g through the ships side
and outboard against the superimposing water. The upward pressure of the water
in the pipe g and chamber f always keeps the valve i fast closed against its seat,
and the valve h is kept against its seat by floatation in the chamber c, and prevents
the water or soil from returning to the pan a. After using the closet, by turning
a tap water is let into the pan a through the flushing pipe b and the pan a is moved
up and down once or twice and the contents driven through the closet into the
sea, the flush tap is then closed and the closet is ready for future use.
The closet pan and parts above the floor are preferably made of a hard white
metal alloy, carrying a very high polish, and non-corrosive, that will not verdigris,
and does not require any cleaning beyond polishing occasionally.
The closets are suitable for cabins (and forecastles) of large ships or yachts and
for small launches or boats where a bucket has hitherto been the only resource,
besides which they are adaptable for cooks' slush buckets or stewards' slop sinks,
and save the nuisance of carrying those things on deck to be emptied (and spilt).
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. A below-water-level water closet or pan constructed and operating substan-
tially as described, that is to say; a water closet or pan in which the pan or basin
is adapted to force out and discharge its contents or soil outboard into the super-
imposing water by being drawn up and forced down in a chamber connected with
a discharge pipe, both the pan and the discharge pipe being provided with valves
as set forth.
2. The improved below-water-level water closet or pan herein described consist-
ing of a pan a having an extension pipe and a valve h, a chamber e in which
the pan a is adapted to be drawn up and forced down, and a discharge chamber f
and pipe having a valve, the pan a discharging its contents against the super-
imposing water on being drawn up and forced down as described.
3. The combination of the water closet or pan a having an extension pipe d
and a valve h, the chamber c adapted to receive the pan a, and the discharge
chamber and pipe g having a valve i as shown in the drawings and operating
as described.
