Year: 1872

page_text: LETTERS PATENT to Henry Grant Spence, of South Stockton-on-Tees,
in the County of York, for the Invention of "IMPROVED ARRANGE-
MENTS FOR CONNECTING THE VARIOUS PIPES, COCKS, AND VALVES TO THE
BOTTOMS AND SIDES OF SHIPS OR VESSELS WITH THE VIEW TO AFFORD GREATER
SAFETY TO SHIPS AND VESSELS."
Sealed tho 5th July 1872, and dated the 6th January 1872.
PROVISIONAL SPECIFICATION left by the said Henry Grant Spence
at the Office of the Commissioners of Patents, with his Petition,
on the 6th January 1872.
I, HENRY GRANT SPENCE, of South Stockton-on-Tees, in the County
3 of York, do hereby declare the nature of the said Invention for
"IMPROVED ARRANGEMENTS FOR CONNECTING THE VARIOUS PIPES, COCKS, AND

page_text: VALVES TO THE BOTTOMS AND SIDES OF SHIPS OR VESSELS, WITH THE VIEW TO
AFFORD GREATER SAFETY TO SHIPS AND VESSELS," to be as follows:-
The first part of this Invention consists in constructing a strong box
or well of iron or other suitable material, which is fixed to the side of
the ship in any suitable position, and rendered perfectly water-tight;
the top or lid of this box or well is secured with bolts and nuts with an
elastic washer to render it perfectly water-tight or rivetted on and access
to the interior provided for by a properly constructed man-hole. In the
centre of this lid I fix a stuffing box of brass or other suitable metal
through which a rod passes, which is carried up to the deck and worked
by a lever or hand wheel.

Office on the 6th July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
GRANT SPENCE, of South Stockton-on-Tees, in the County of York,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of January, in the
year of our Lord One thousand eight hundred and seventy-two, in
the thirty-fifth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Henry Grant Spence, Her
special licence that I, the said Henry Grant Spence, my executors,
administrators, and assigns, or such others as I, the said Henry Grant
Spence, 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,
usc, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVED ARRANGEMENTS FOR CONNECTING THE VARIOUS PIPES, COCKS, AND
VALVES TO THE BOTTOMS AND SIDES OF SHIPS OR VESSELS WITH THE VIEW TO
AFFORD GREATER SAFETY TO SHIPS AND VESSELS," upon the condition
(amongst others) that I, the said Henry Grant Spence, 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 im-
mediately after the dato of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Grant Spence, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement :-

page_text: the side of the ship in any suitable position, and rendered perfectly
water-tight; the top or lid of this box or well is secured with bolts and
nuts with an elastic washer to render it perfectly water-tight or rivetted
on and access to the interior provided for by a properly constructed
man-hole. In the top of this box brass or suitable stuffing box and rod
arrangements are provided so that the same may be worked from the
deck by a lever or hand wheel. Valve arrangements of suitable form are
secured to the ship's side inside the aforesaid box or well, and com-
municate with the sea outside by means of grating arrangements, such
valve arrangements being operated by the above-named rod arrangements
in the manner illustrated by the accompanying Drawings. I affix all the
cocks, valves, and other connections to the outside of the above-named
box or well so as to have only the minimum amount of opening to the
water in the ship's side or bottom, and in practice I prefer to use only
one or two openings (two being shown by the accompanying Drawings)
instead of a larger number of openings as hitherto the case, rendering
the safety of the ship dependent on the tenacity of each individual
connection which may be liable to damage in various ways.
which more fully describe the said Invention and particularly describes 20
and ascertains in what manner the same is to be performed or put in
practice.
Fig. 1, section of a ship or vessel with my Invention applied thereto
and showing section of the box above mentioned; Figs. 2 and 3, detail
views. In said Figures A denotes main Kingston valve; B, blow-off 25
Kingston valve; O, injection valve; D, ballast valve; E, blow-off cock;
F, donkey suction cock; G, water service cock; H, water to stoke
hole cock; J, drain cock.
Having now particularly described and ascertained the nature of my
said Invention, and in what manner the same is to be performed or 30
carried out in practice, I declare that I claim the herein-before described
Invention of "Improved Arrangements for Connecting the various Pipes,
Cocks, and Valves to the Bottoms and Sides of Ships or Vessels, with the
View to Afford Greater Safety to Ships and Vessels," whereby the con-
nection with or openings to the sea or water are reduced to a minimum 35

page_text: instead of, as in the ordinary way, having a separate opening in the skin
of the ship for each cock, valve, or pipe. However I do not confine myself
to the particular shape of valves or mode of working them shown by the
Drawings and herein described, but reserve the right to apply in any
suitable and convenient manner, working them either from the deck or
below, or in conjunction.
In witness whereof, I, the said Henry Grant Spence, have hereunto
set my hand and seal, this Twenty-fifth day of June, in the year
of our Lord One thousand eight hundred and seventy-two.
HENRY GRANT SPENCE. (L.S.)
Witness,
