page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
DODD, of Saint Anne Street in the County of Middlesex, Engineer, send
greeting.
WHEREAS His most Excellent Majesty King George the Fourth, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-first day of October, in the fifth year of His
reign, did, for Himself, His heirs, and successors, give and grant unto me,
the said George Dodd, His especial licence that I, the said George Dodd,
my exors, adñiors, and assigns, or such others as I, the said George Dodd,
my exors, adiiors, 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
expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, and also
in all His said Majesty's Colonies and Plantations abroad, my Invention
of "CERTAIN IMPROVEMENTS IN FIRE-EXTINGUISHING MACHINERY;" in which said
Letters Patent there is contained a proviso obliging me, the said George
Dodd, by an instrument in writing under my hand and seal, particularly to
describe and ascertain the nature of my said Invention, and in what manner
the same is to be performed, and to cause the same to be enrolled in His
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said 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
George Dodd, do hereby declare the nature of my said Invention to consist
in an apparatus applied to the water or branch pipe of a fire engine, by which
the direction given to the water issuing from it may be ascertained, or nearly

page_text: the figures marked thereon, that is to say:-
DESCRIPTION OF THE DRAWING.
In Figure 1, A represents the ordinary branch pipe of a fire engine, passed
downward through a hole in the deck of a vessel supposed to be on fire, and
secured in that position by means of an adjusting flango B at the lower end of
this branch pipe, the moveable end or nose piece C is attached by means of
an universal tubular or hollow joint. At the upper end of the said branch
pipe is attached the lever D, turning on a pivot or centre at r, and having a
handle S to be moved by the operator. E is a connecting rod fastened at one
end to the lever D, by means of a pivot at e, on which it turns, and at the
other end to the nose piece C, by means of a similar pivot at f. Now it will be
seen that the lever D and the nose piece C, being connected together by
means of this rod E, the motions of each will be dependent on the other, and
if the upper end of the rod at e be the same distance from the pivot or centre r
that the lower end of the rod at fis from the universal joint of the nose
piece C, every motion given by the operator to the lever D will cause
corresponding motion of the nose piece C; that is to say, if the handle of the
lever D be raised by the operator it will cause nearly a similar elevation of the
nose piece C, and vice versa; if the handle of the lever D be depressed
it will cause nearly a similar depression of the nose piece C. By this
arrangement it will be seen that if it were required to direct the jet or
stream of water from the branch pipe of a fire engine to the spot F, in
the between decks of a vessel; the said pipo might be passed downward
through the deck of the vessel, in manner here represented Figure 10, while
a person on deck at G, who could not see the nose piece, nor consequently
the stream of water, by raising the handle S of the lever D, till the end H of
the lever pointed to the spot F would raise the nose piece C to a corresponding
elevation, by which means the stream of water would be directed to the spot F,
which is supposed to be the place where the fire is burning.
Now whereas in the Drawing hereunto annexed I have shewn several
modifications of my said Invention, by which it may be the better adapted to
the various necessities in which it is likely to be called for, but whereas, the
principle of the said Invention is the same in all of them; now, therefore, I
do hereby claim as my Invention a moveable nose piece. connected by

page_text: means of a rod to and moved by the elevation or depression of a lever or
arın, which lever or arm answers the purpose of a sight, in such manner,
that by the pointing of the end of this lever or sight towards the spot where
it is intended the water shall be thrown, shall point the nose piece also
nearly to the same spot, and thus direct the water there, without its being
necessary for the operator to see either the moveable end or nose piece, or the
jet of water; and this apparatus and the application thereof to the purpose
aforesaid, being to the best of my knowledge and belief entirely new, and never
before used in that part of His said Majesty's United Kingdom of Great Britain
and Ireland called England, His Dominion of Wales, or Town of Berwick-
upon-Tweed, and also in all His said Majesty's Colonies and Plantations.
abroad, I do hereby declare this to be my Specification of the same, and that
I do verily believe this my said Specification, doth comply in all respects, fully
and without reserve or disguise, with the proviso in my said herein-before in
part recited Letters Patent contained.
Wherefore I do hereby claim to maintain exclusive right and privilege to
my said Invention.
In witness whereof, I, the said George Dodd, have hereunto set my hand
and seal, this Eighth day of March, in the sixth year of the reign of
His Majesty King George the Fourth, and in the year of our Lord One
thousand eight hundred and twenty-five.
