Year: 1736

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JONATHAN
HULLS, send greeting.
WHEREAS our Sovereign Lord George the Second, by the Grace of God
King of Great Britain, &c., hath by His Letters Patent under His Great
Seale of Great Britain, bearing date at Westm', the Twenty-first day of
December, in the tenth year of His reign, given and granted unto me, the said
Jonathan Hulls, my exors, admors, and assigns, His especiall license, full
power, sole priviledge and authority, to make, use, exercise, and vend my new
Invention of "A MACHINE FOR CARRYING SHIPS AND VESSELS OUT OF OR INTO
ANY HARBOUR AND RIVER AGAINST WIND AND TYDE, OR IN A CALE," within that
part of Great Britain called England, His Dominion of Wales, and Town of
Berwick-upon-Tweed, in such manner as to me, the said Jonathan Hulls, my
exors, adñors, and assigns, or any of us, shall in our discretions seem meet, to
havé, hold, exercise, and enjoy the said lycense, powers, priviledges, and advan-
tages unto me, the said Jonathan Hulls, my exors, admors, and assigns, for
and during the terme of fourteen years from the date thereof, according to the
Statute in such case made and provided; in which said Letters Patent there is
contained a provisoe that if I, the said Jonathan Hulls, should not particularly
describe the nature and forme of my said Invention by an instrument in
writing under my hand and seal, and cause the same to be inrolled in the
High Court of Chancery within three calendar months next and imediately
after the date of the said Letters Pattent, that then the said Letters Pattent
should be void, as in and by the said recited Letters Pattent (relačon being
thereunto had) may more fully and at large appear.

page_text: NOW KNOW YE, that I, the said Jonathan Hulls, pursuant to tho said
provisoc, have described and ascertained, and by these presents do describe and
ascertain, the nature and form of my said Invention to consist in manner
following (that is to say):-
Of two beams of timber laid paralel to each other, between which and near
each end thereof is fixed an axis, and behind the fore axis is fixed a standard
of one or more upright peice or peices of timber, with pulley or small wheel
on the top; on the said fore axis is fixed three wheels, and on the bindermost
axis two wheels, with an intervening space, in which space are fixed six fanns
that turn upon that axis; to each of the outermost wheels on the fore axis is
fixed a rope, one end of which is also fixed to the bindermost corresponding
wheels, and directed in an alternate manner, and another rope is to go from
the left hind wheel over the standard, with a largo weight at the end, so that as
the wheels move backward or forward the fans are brought into and keep
a direct motion in the water, which forces forwards the vessell in which the
machine is placed. The power that is to put and keep this machine in motion
is a fire engine, which operates upon the machine in the following manner :-
A rope is fixed at one end to the middle of the wheel on the fore axis, and the
other end to a piston which goes into a cylinder vessell placed near a boyler,
containing a proper quantity of water, in which boyler the water is rarifyed,
and from thence the stream is conveyed into the cylinder vessell, and there con-
densed, in order to obtain a vacuum, which causes the weight of the atmo-
sphere to press on the piston, and so gives motion to the whole machine.
This machine is to be placed and fixed on board the ship or vessell which is to
be carryed out of or into any harbour or along a river, but rather in a tow
boat, to be used for that purpose in shallow rivers. This machine, instead of
fanns, works by two cranks fixed to the hindermost axis, to which cranks are
fixed two shafts of proper length to reach the botom of the river, and which
move alternately forward from the motion of the wheels by which the vessell
is carryed on. For smooth and deep waters the beams of the machine will bo
made shorter, and proper fanns fixed to work on each side the vessell.
In witness whereof, I have hereunto sett my hand and seal, the Seventh
day of March, in the tenth year of the reign of our Sovereign Lord
King George the Second, over Great Britain, &c., and in the year of
our Lord One thousand seven hundred and thirty-six.
Sealed and delivered (being first duly
stampt) in the presence of
THO. MATHEW,
JA HEN. KENT.
