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 the 27th April 1875, and dated the 4th February 1875.
PROVISIONAL SPECIFICATION left by the said Henry Grant Spence
at the Office of the Commissioners of Patents, with his Petition,
on the 4th February 1875.
I, HENRY GRANT SPENCE, of South Stockton-on-Tees, in the County
of York, do hereby declare the nature of the said 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," to be as follows:-
The present Invention relates to improvements upon the Invention
patented by me, dated January 6th, A.D. 1872, No. 56, and consists in

page_text: constructing not less than two strong boxes or wells of iron or other
suitable material fixed to the sides of the ship in any suitable position,
and rendered perfectly water-tight.
The top or lid of cach 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 is provided for by a properly constructed man-hole.
In the top of each box, brass, or suitable stuffing box and rod arrange-
ments 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 boxes or wells communicating with the sea outside
by means of grating arrangements, such valve arrangements being
operated by the above-named rod arrangements.
One of the aforesaid boxes or wells contains the injection valve, and
the other the blow-off cock. By these arrangements I have the minimum
amount (that can be advantageously adopted) of opening to the water in
the ship's sides or bottom, a matter of great importance for the safety
of the ship.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Grant Spence in the Great Scal Patent
Office on the 4th August 1875.
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 Fourth day of February, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Grant Spence, Her special
licence that I, the said Henry Grant Spence, my executors, adminis-
trators, 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, use,

page_text: Fig. 4, section shewing blow-off cock.
Fig. 5, enlarged view of blow-off cock.
A, main Kingston valve; B, blow-off Kingston valve; O, injection
valve; D, ash cock; E, blow-off cock; F, donkey suction pipe; G,
water service cock; H, 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
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 connection with or openings to the sea or water are reduced to a
minimum, as herein-before set forth and described, it being understood
that I do not limit myself to the precise arrangements shewn by the
Drawings, and herein-before described with reference thereto.
In witness whereof, I, the said Henry Grant Spence, have hereunto
set my hand and seal, this Second day of August, in the year of
our Lord One thousand eight hundred and seventy-five.
Witness,
HENRY GRANT SPENCE. (L.S.)
