page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, JOHN KENT,
of the Town and County of the Town of Southampton, Architect, send
greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twelfth day of March,
in the fiftieth year of His reign, give and grant unto me, the said John
Keut, my exors, admors, and assigns, His especial licence, that I, the said
John Kent, my exors, admors, and assigns, during the term of fourteen 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 "A NEW AND EXPEDITIOUS METHOD OF MOVING ALL KINDS OF GOODS OR
MATERIALS TO HIGH BUILDINGS OR FROM DEEP PLACES;" in which said Letters
Patent there is contained a proviso, obliging me, the said John Kent, by an
instrument in writing under my hand and seal, to 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 Majesty's High Court of Chancery within two
calendar months after the date of the said recited Letters Patent, as in and
by the same, relation being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Kent, do hereby declare that my said Invention is described in manner
following, that is to say:-
My said Invention is an improvement on the principle of a lever on a
moving fulcrum, whereby power is gained without loss of time, as more fully
appears by reference to the Drawings annexed, N° 1 and 2. The Drawings

page_text: N° 1 represent a body or weight to be raised, which is supposed to weigh
4 hundred weight, and to be suspended by a rope or chain passing over the
pulley B, and fastened at one end to the weight A, and at the other end to
the centre of the wheel C, which wheel C is supposed in itself, or by weight
attached to it, to be heavier than the weight A, which is to be raised. Now,
it is evident that if a power be applied to the top of the wheel C of 2 hundred
weight, as at D, or a similar weight to act as a power, as at E, that it will
balance the weight A of four hundred weight, because the power is applied at
double the distance that the weight to be raised is from the moving fulcrum,
which is at the bottom of the wheel C; and if the wheel C be rolled along on
au horizontal plano, as the line F represents, the weight A must necessarily
bo raised as much as the wheel C moves in the surface of the horizontal
line or plane which supports it. The Drawings N° 2 explains my said
Invention in a compound manner, viz., A, the weight to be raised of
4 hundred weight; B, the pulley over which the rope or chain passes from
the said weight to the centro of the wheel C; D, another wheel joined at its
moveable centre to the moveable centre of the wheel C by an iron plate, or
otherwise, on each side of the sustaining or friction wheels C and D; E, a
roller of sufficient weight to roll on the two sustaining or friction wheels C
and D. Now, it is also evident that if a power be applied to the centre of the
roller E, as at F, of something more than 2 hundred weight, it will move the
snid roller round its axis towards the wheel C, by its rolling off the said
sustaining wheel D, on the said sustaining wheel C, and will thereby mové
the said sustaining wheel towards the power F, and will lift up the weight A ;
and if the power at F, where joined with iron, or any other proper material,
from the centre of the roller E to the centre of the other similar sustaining
wheels, as from E to K, or in an horizontal direction to the iron or other
metal plates that are shewn by the yellow shade of a semi-circular form, or by
any other means, from E to G, and also from H to I, as in Number four, it
would continue to increase the power one half by every pair of such sustaining
or friction wheels and roller that may thus be added; viz, the first pair of
sustaining or friction wheels and roller, marked 3, will balance four hundred
weight by a power of two hundred weight; and the second pair of sustaining
'or friction wheels and rollers, marked 4, will balance 2 hundred weight
by a power of 1 cwt.; and a third pair of sustaining wheels and rollers,
if added, would balance 1 hundred weight by a power of half a hundred
weight, and so on; all which is effected by rolling the sustaining wheels
and rollers on the horizontal plane by means of joining the sustaining
⚫ wheels together, from the centre of each roller to the centre of each pair

page_text: of the sustaining or friction wheels, or to the iron plates, or otherwise, in
an horizontal direction, which hold the sustaining wheels together, so that by
adding a continuation of sustaining or friction wheels and rollers any power
may be gained without loss of time, provided that the said rollers which are
laid on the said sustaining or friction wheels are of a sufficient weight in them-
selves, or by weight attached to them, either by being suspended to the axis
of the said rollers, or bearing on their axis, or any other way, as occasion may
require, and to which sustaining wheels and rollers fly wheels may be added if
required. The rollers, in some cases, must be of a cylindrical, and at other
times of a conical or any other convenient form, and are also to be made to
roll either on a horizontal plane or over an inclined plane, as occasion may
require. The Invention, as before described, I apply to a direct, a rotative, a
pendulum, a crank, or any other kind of motion that will produce the various
effects required. The Drawings annexed are so clearly explained that by
inspection any competent mechanic can apply my said Invention to any
machinery he may think proper. The various machines that may be required
must necessarily differ in form and make, and be composed of different kinds
of materials, as occasion may require, and may be worked either by animal
strength, by water, by wind, by steam, or by any other kind of agent that may
be best adapted to the place and purpose required; and although my said
Drawings show my said Invention as applied only to raising weight, yet my
said Invention is also applicable to mills, to pumps, to moving carriages on
iron railways, and to various other kinds of machinery.
In witness whereof, I, the said John Kent, have hereunto, set my hand
and seal, the Twelfth day of May, in the year of our Lord One
