A NEW MODE OF OVERCOMING RESISTANCE IN MECHANICAL OPERATIONS BY MAN OR BEAST
Year: 1788

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, WILLIAM
JOHNSON and MARK NOBLE, of Torrington Street, Ratcliffe Highway, in the
County of Middlesex, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fifteenth day of. April, in the twenty-eighth year of His
reign, did give unto the said William Johnson and Mark Noble His especial
licence that they, the said William Johnson and Mark Noble, during the
term of years therein expressed, should and lawfully might make, use, exercise,
and vend, within that part of the Kingdom of Great Britain called England,
the Dominion of Wales, and Town of Berwick-upon-Tweed, their Invention of
"A NEW MODE OF OVERCOMING RESISTANCE IN MECHANICAL OPERATIONS BY MAN OR
BEAST;" in which said Letters Patent there is contained a proviso obliging the
said William Johnson and Mark Noble, by an instrument in writing under
their hands and seals, to cause a particular description of the nature of their
said Invention, and how the same is to be performed, to be. inrolled in His
Majesty's High Court of Chancery within one calendar month next 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 pursuance of the said proviso, they, the said
William Johnson and Mark Noble, do hereby declare that their said Invention
of A New Mode of Overcoming Resistance in Mechanical Operations by Man
or Beast is described in the Plans drawn in the margin hereof, and by the
referrences thereto as after mentioned (that is to say):-

page_text: enable the man at D to raise one hundred pounds at A by exerting but a
power of fifty pounds at an equal extremity of the leaver at B, making just
allowance for friction. Also to this same advantage, if the man at C lifts fifty
pounds at A, he becomes fifty pounds heavier, and from the same communica-
tion of the upper with the lower leaver can raise one hundred pounds by
exerting a power of fifty pounds. That the same plan may be understood for
horses, omit the barrs F, F. Let E represent the mill post of a horse wheel;
A, B, the upper wheel, to which the traces are fixed; C, D, another wheel, on
which the horse walks, and which, by the weight of his body or force of his
feet, when he draws the upper wheel, moves in a contrary direction, both of
which wheels are to be fixed on distinct spindles in the same direction, the
spindle of the upper wheel resting on and moveing in a socket H on the spindle
of the lower wheel. G, by a dotted circle, represents a wallow wheel, to which
the upper and lower main wheels communicate. The lower wheel or bed
on which the horse walks must be supported on rollers or friction wheels.

page_text: The whole perfection of this Invention consisting in this, that to move a
resistance of one hundred pounds through the space of one foot may be effected
by the labour of first exerting, with the hands or otherwise, but a power of fifty
pounds through the space of one foot, making proper allowance always for
friction, and this advantage being obtained by rendering the weight of the
body, or giving a power to the feet equal in advantage to the power first
exerted by the present general or particular mode of labour, and which may,
by different ways, be communicated to a variety of machines.
In witness whereof, they, the said William Johnson and Mark Noble,
have hereunto set their hands and seals, this Fourteenth day of
May, in the year of our Lord One thousand seven hundred and eighty-
eight.
WILLIAM (L.S.) JOHNSON.
MARK (L.s.) NOBLE.

Inrolled the said Fourteenth day of May, in the year last above
written.
