BARTON, of Falcon Square, in the City of London, Engineer, send greeting.
WHEREAS His most Excellent Majesty King George the Fourth did, by
His Letters Patent under the Great Seal of that part of the United Kingdom
of Great Britain and Ireland called England, bearing date at Westminster, the
Fifteenth day of May, in the first year of His reign, give and grant unto me,
the said John Barton, my exors, adñiors, and assigns, His especial licence, full
power, sole privilege and authority, that I, the said John Barton, my exors,
adiñors, and assigns, 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, and also in all His Majesty's Colonies and
Plantations abroad, my Invention of "CERTAIN IMPROVEMENTS IN PROPELLING,
AND IN THE CONSTRUCTION OF ENGINES AND BOILERS APPLICABLE TO PROPELLING AND
OTHER PURPOSES;" in which said Letters Patent there is contained a proviso
that if I, the said John Barton, shall not particularly describe and ascertain
the nature of my said Invention, and in what manner the same is to be
performed, by an instrument in writing under my hand and seal, and cause the
same to be inrolled in His Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said Letters
Patent, that then the said Letters Patent, and all liberties and advantages
whatsoever thereby granted, shall utterly cease, determine, and become void,
as in and by the same, relation being thereunto had, will more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Barton, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained in and by the Drawings hereunto annexed, and the following
description thereof (that is to say):-
My Invention, as it respects boilers, is in their construction of a strong figure,
and to make the flues for the fire and smoke so as to expose a large surface of
fire to the fluid, that the heat may have to ascend as much as possible in every
part I can, to act against a part of the boiler where there is water adjoining,
and of such a shape that they may work without any surrounding brickwork if
desired, as shewn in Figure 1, end,view, and Figure 2, a side section; a, a,
shews the fire-place; b, b, shews;,the form and situation of the flues, which
go from the fire-place a, a, and then ascend into the curved flue 61, from
which it returns towards the fire-place to the flue 6-2; when it returns round
the pipe c (which is full of water, and divides these two flues, when it goes
towards the chimney or pipe 6'3, where the smoke goes away. Fig. 3 is a
side section, of, part of a pump or engine with a hollow. rod, which I claim
as my Invention; it answers both for the pump rod and raising main for the
water to ascend in the inside of the rod, and is, connected at top, by a joint or
any other method to allow the water to run off. Fig. 4 shews a section of a
cock in the cylinder cover of the engine for feeding it with grease, oil,.or
any other fluid without. admitting air; or as at. Figure 5, may be used for
feeding an engine with water, as it answers the purpose of a double cock; these
may be made to revolve by machinery, so as to give the exact supply required,
or it may be made to raise and fall with a float in. the boiler, and may be
used for various other purposes, and the chamber must be made larger or
smaller according to the use intended or quantity of fluid required. Figure .6
shews the cylinder lid, with the cock, Figure 4, shewn on a smaller. scale.
Fig. 7 shews the end section of my engine for raising water or, other pur-
poses, and is well adapted for a fire or a blowing engine, as it works with
little friction, and has a tendency to improve by use; it is shewn with the fan
or piston, which is metallic, going towards the left, on which side it is forcing
the water up, and the upper valve is open on that side, and it forms a vacum
on the other side, and shuts the top valve and opens the bottom valve to the
suction, so that these valves act alternately, and raise water at the raising and
depressing of the handles. Fig. 8 is a plan of segments of the metallic piston
or fan, which is pressed against the diameter and ends of the cylinder or
working piece of the engine by the dark springs. Figure 9 is an end view
of my wheel or drum, made hollow as far as the dotted lines, for propelling
.

it has a tendency of keeping the proper depth in the water, so that the paddles
act with the greatest effect. Fig. 10, an end view of ditto.
In witness whereof, I, the said John Barton, have hereunto set my
hands and seal, this Fifteenth day of November, in the year of our
Land One thousand sight hundred and tmanty
