IMPROVEMENTS APPLICABLE TO WATERCLOSETS IN SHIPS AND VESSELS
Year: 1868

page_text: LETTERS PATENT to John Hays Wilson, of Liverpool, in the County
of Lancaster, for the Invention of "IMPROVEMENTS APPLICABLE TO
WATERCLOSETS IN SHIPS AND VESSELS."
Sealed the 7th May 1869, and dated the 10th November 1868.
PROVISIONAL SPECIFICATION left by the said John Hays Wilson at
the Office of the Commissioners of Patents, with his Petition, on
the 10th November 1868.
I, JOHN HAYS WILSON, of Liverpool, in the County of Lancaster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS
APPLICABLE TO WATERCLOSETS IN SHIPS AND VESSELS," to be as follows:-
My improvements refer to the adoption of the following arrangements
in waterclosets for ships and vessels, that is to say, I construct the same
with dry wells or cisterns to receive after use the contents of such
closets, to be emptied when necessary by force or lift pump, or by
compressed air, by which means the contents of the cistern or dry well
may be emptied at any required height. The cistern into which the
closets discharges I prefer to provide with a lift pump, with discharge

page_text: ⚫or nozzle coming through the sides of the ship or vessel, and an air
pipe leading from the cistern and opening also through the sides of the
ship for the purpose of preventing accumulation of gas. Although I
prefer to adopt the method of emptying the cistern or dry well above
described I do not confine myself thereto, as the same object may be
accomplished by other means.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Hays Wilson in the Great Seal Patent Office
on the 8th May 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HAYS WILSON, of Liverpool, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of November, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Hays Wilson, Her special licence
that I, the said John Hays Wilson, my executors, administrators, and
assigns, or such others as I, the said John Hays Wilson, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS APPLICABLE TO
WATERCLOSETS IN SHIPS AND VESSELS," upon the condition (amongst others)
that I, the said John Hays Wilson, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said John Hays Wilson, do hereby
declare the nature of my said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement :-
My improvements comprise the adoption of the following arrange-
ments in waterclosets for ships and vessels, that is to say, I
construct the same with dry wells or cisterns to receive after use
the contents of such closets, so that the same may be emptied when
necessary by force or lift pump arrangements, or by compressed air
arrangements, or by other suitable means, whereby the contents of the
cistern or dry well may be emptied at any required height. The
cistern or dry well into which the closet discharges I provide
with a pump, with discharge or nozzle coming through the sides of
the ship or vessel, and with an air pipe leading from the cistern, and
opening also through the sides of the ship for the purpose of preventing
accumulation of gas.
Having now described the nature and purpose of my said Invention
I will now proceed to particularly describe and ascertain in what manner
the same may he performed or put in practice, which I shall do by
reference to the accompanying Drawings, that is to say :-
Fig. 1 an elevational view of a ship's closet with my improvements
applied thereto.
A, cistern or reservoir into which the closet discharges; B, lift pump
with discharge or nozzle (6) passing through side of ship; C, air pipe
leading from cistern or reservoir (A) and opening through side of ship
for the purpose of carrying off the gas arising in the reservoir and pre-
venting its accumulation; D, section of deck of ship or vessel; E, cap
or cover of pump. The pump is closed flush with the deck, so as to
be out of the way, and when it is required to be used the cap E is
removed to allow of the application of a hand lever or other mechanism
for working the pump.
Having now particularly described and ascertained the nature of
my said Invention, and in what manner the same is to be performed or
carried out in practice, I hereby declare that I claim the "Improve-
ments applicable to Waterclosets in Ships and Vessels," as herein-before
described, it being understood that I do not limit myself to the details

page_text: of construction herein-before described and illustrated by the Drawings
accompanying these Presents, nor do I claim such details per se and
apart from the objects and purposes of my said Invention.
In witness whereof, I, the, said John Hays Wilson, have here.
unto set my hand seal, this Third day of May, in the year of t
our Lord One thousand eight hundred and sixty-nine.
Witness;
EDW. W. WEST.
JOHN HAYS WILSON. (L.S.)
