Improvements in or relating to Ships' Water Closets.
We, BLUNDELL'S LONDON COPPER AND BRASS WORKS LIMITED, of
23 and 25 West India Dock Road, Limehouse, in the County of London,
Engineers and Coppersmiths, and HENRY IVES, of the same place, Managing
Director of the said Company, do hereby declare the nature of this invention to
be as follows:-
Underline closets when fitted in the usual way on board ship are not easy to
work inasmuch as considerable force has to be exerted to operate the pump by
which they are emptied. They are therefore not suitable for use by invalids, weak
persons or children.
Now the object of our invention is to overcome this objection and for this
purpose we combine with a ship's closet an upper pan or basin and flushing
arrangements this pan being fitted with any suitable valve at bottom to retain
water and to permit of the discharge of the soil into the lower or ordinary pan of
the closet. The lower pan is hermetically closed by a cover in which the seating
for the valve of the upper pan may conveniently be formed. A vent pipe leading
overboard is fitted to the lower pan either in or below the cover.
With this arrangement an underline ship's closet can be worked in the same way
and with the same ease as an ordinary house closet. The closed lower pan forms a
receptacle for the soil discharged from the upper pan, and this soil can be pumped
overboard from time to time by a person appointed for the purpose by means of the
usual pump and the pans can also be thoroughly flushed so that they are kept clean
and sweet.

Improvements in or relating to Ships' Water Closets.
We, BLUNDELL'S LONDON COPPER AND BRASS WORKS LIMITED of
23 and 25 West India Dock Road, Limehouse in the County of London,
Engineers and Coppersmiths and HENRY IVES of the same place, Managing
Director of the said Company, 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 :-
Underline closets when fitted in the usual way on board ship are not easy to
work inasmuch as considerable force has to be exerted to operate the pump by
which they are emptied. They are therefore not suitable for use by invalids, weak
persons or children.
Now the object of our invention is to overcome this objection and for this
purpose we combine with a ship's closet an upper pan or basin and flushing
arrangements, this pan being fitted with any suitable valve at bottom to retain
water and to permit of the discharge of the soil into the lower or ordinary pan of
D021

page_text: the closet. The lower pan is hermetically closed by a cover in which the seating
for the valve of the upper pan may conveniently be formed. A vent pipe leading
overboard is fitted to the lower pan either in or below the cover.
With this arrangement an underline ships' closet can be worked in the same way
and with the same ease as an ordinary house closet. The closed lower pan forms a
receptacle for the soil discharged from the upper pan, and this soil can be pumped
overboard from time to time by a person appointed for the purpose by means of the
usual pump and the pans can also be thoroughly flushed so that they are kept clean
and sweet.
Figure 1 of the accompanying drawings is a side elevation and Figures 2 and 3
are end elevations of an underline water closet constructed in accordance with this
invention.
A is the upper pan or basin made preferably of china ware carried in a metal
casing. This pan is fitted with a valve B which in the arrangement shown is
worked by the handle in the cup C through the intermediation of the slotted
lever D. The valve B normally retains water in the pan and when open permits
of the discharge of the soil. In the arrangement shown the lever D in addition to
working the valve B also opens and closes the flushing valve E which is so fitted
as when open to give passage to water to flush the pan and then an after flush in
the manner well understood so as to seal the joint at the valve B. A separate cock
worked by independent handle may however be used for admitting and shutting off
the water. G is the lower or ordinary pan preferably made of metal enamelled
inside; it is hermetically closed by a cover F which carries the upper pan A and
in which cover the seating for the valve B is formed. H is a vent pipe fitted in
the cover F and leading overboard, thus allowing air to escape freely from the
lower pan G. The lower pan receives the soil and water discharged from the
upper pan A through the valve B and these can be pumped overboard from time to
time by a person appointed for the purpose by means of the usual pump I, and as
has already been stated the pans can also be thoroughly flushed so that they are
kept clean and sweet.
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
1. In underline water closets the combination with a pan or receptacle and pump
for pumping the contents of same overboard, of an upper pan or basin and flushing
apparatus arranged so that the contents of the upper pan are discharged into the
lower pan substantially as and for the purpose herein before described.
2. The improved ships' water closet hereinbefore described with reference to the
accompanying drawings.
Dated this 2nd day of January 1895.
