page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN HAYWOOD,
of Long Acre, in the Parish of Saint Martin in the Fields, in the County of
Middlesex, Draftsman and Mechanic, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Eighth day of May, in the thirtieth year of His reign, hath given
and granted unto the said John Heywood, his executors, administrators, and
assigns, Ilis especial licence, full power, sole privilege and authority, that he,
the said John Haywood, his exccutors, administrators, and assigns, and every
of them, by himself and themselves, or by his and their deputy or deputies,
servants or agents, or such others as he, the said John Haywood, his executors,
administrators, or assigns, should at any time agree with, and no others, from
time to time, and at all times thereafter, during the term of years therein
expressed, should and lawfully might make, use, exercise, and vend his
Invention of "A MACHINE FOR WORKING MILLS AND ENGINES WITHOUT THE AID
OF FIRE, WATER, OR WIND, OR IN AID OF ALL OR ANY OF THOSE OR ANY OTHER
POWERS," within that part of Great Britain called England, the Dominion
of Wales, and Town of Berwick-upon-Tweed, and also in all His Majesty's
Colonies and Plantations abroad, in such manner as to him, the said John
Haywood, his executors, administrators, and assigns, or any of them,
should, in his or their discretions, seem meet; in which said Letters Patent

page_text: is contained a proviso that if the said John Haywood shall not particularly
describe and ascertain the nature of his said Invention, and in what manner
the same is to be performed, by an instrument in writing under his hand and
seal, and cause the same to be inrolled in His Majesty's High Court of
Chancery within one calendar month 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, should utterly cease, determine,
and become void, as in and by the said in part recited Letters Patent, relation
being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with and agreeable to the true
intent and meaning of the said proviso in the said Letters Patent contained,
I, the said John Haywood, do hereby declare the nature of my said Invention,
and the manner in which the same is to bo performed, is and aro described
and ascertained in manner following (that is to say):-
The machine acts on a rotative principle, or, in other words, lins a revolving
circular or circulating motion round an axis, center, or centers. It may be
made or constructed of any materials or matter whatsoever, so it be of suffi-
cient strength to sustain the power of action when applied to any mill, engine,
or machine to which action or motion can or may be communicated by a wheel.
The size or dimensions of this machine are by no means confined, but may be
varied or altered as circumstances may require.
References to the Plan and Drawings of the machine hereunto annexed:-
Figure 1 is a plan of the machine. Figure 2 is the elevation of the machine.
Figure 8 is the section of the machine. A, A, B, a cranked or double center,
fixed to the stand or framo D by the bolts E. C, C, the wheel which turns or
revolves round that part of the cranked center mark A. D, the stand or frame of
the machine. E, the bolts which fasten the center or crank to the stand or frame.
F, levers which turn or revolve round the cranked center B, by means of tho
threadled centers M in Figure 1. G, G, rollers or weights which revolve in
the circular guides or grooves marked H in Figure 3, by means of the leavers
F. H, H, circular grooves or guides which are affixed to the inner sides of
the wheel. N.B.-The distance from A to B is the radius in all cases to
determine the space between the center of the guide or groove H and the
center of the roller or weight G. The distance of the two concentric circles
which form the guides or grooves H must be equal to the diameter of the
roller or weight G. I, I, springs which stop the rollers or weights G from
returning when at the horizontal diameter of the wheel. K, weights, which
may be increased or diminished at pleasure. L, ledges which connect the
sides of the wheel together. N.B.-By fixing cogs or teeth on the rim of the

page_text: wheel, so as to connect it with any mill, machine, or engine to which motion
can be given by a wheel, the power of this machine may be communicated.
In witness whereof, I, the said John Haywood, have hereunto set my
hand and seal, this Eighth day of June, in the year of our Lord One
thousand seven hundred and ninety.
Inrolled the said Eighth day of June, in the year above mentioned.
