CERTAIN IMPROVEMENTS IN SHIPS' SCUPPERS, AND WHICH MAY BE APPLIED TO OTHER PURPOSES
Year: 1829

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WILLIAM DODGSON, of Lower Shadwell, in the County of Middlesex, Pump
and Engine Maker, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth
did, by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Seventeenth day of November, in the tenth year of
His reign, give and grant unto me, the said John William Dodgson, His
especial licence that I, the said John William Dodgson, my exors, admors,
and assigns, and such others as I, the said John William Dodgson, my
exors, admors, or assigns, should at any time agree with, and no others, from
time to time and at all times during the term of years therein mentioned,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "CERTAIN
IMPROVEMENTS IN SHIPS' SCUPPERS, AND WHICH MAY BE APPLIED TO OTHER PURPOSES;"
in which said Letters Patent is contained a proviso that I, the said John
William Dodgson, shall cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, to be
inrolled in His said Majesty's High Court of Chancery within six-calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John William Dodgson, do declare that my Invention is fully described and

page_text: ascertained by the following description thereof,, reference being had to the
Drawing in the margin, and to the figures and. letters marked thereon, that
is to say:-
Fig. 1 represents the section of a scupper constructed according to my
improvements. a, the barrel which passes through the side of the ship;
b, a valve hinged on to the cover.c.at.w, which cover is screwed on to the
barrel by screw bolts d, dd. Now it will be seen that water coming against
the valve 6 (in the direction of the arrow) will open it and pass off, but will
be prevented returning in consequence of the valve only being able to open
one way.
Fig. 2 is another scupper, which is to be used in a vertical or other position;
and it will be seen that the same letters indicate similar parts as in the
foregoing Figure, and the only difference is that the valve b is weighted on
the other side of the fulcrum at e, by which means it will always be kept up
to its, place, excepting when water is running through, which overcoming the
weight causes the valve to open, but when the water has passed off the valve
will be closed by the weight e.
Now it will be evident that these scuppers may be made of any material,
but for sea service they should be constructed of metals which are not acted
upon by the sea water.
In witness whereof, I, the said John William Dodgson, have hereunto:
'set my hand and seal, this Seventeenth day of May, in the year of our
Lord One thousand eight hundred and thirty.
DOWDESWELL.
JOHN WILLIAM (L.S.) DODGSON.
