of Caerleon, in the County of Monmouth, Esquire, sends greeting.
WHEREAS the said John Butler did, by his Petition, humbly represent
unto His most Excellent Majesty King George the Third, that he, the said
John Butler, had by great study invented "A NEW METHOD OF MAKING BOLTS
AND BRAZIER OR OTHER RODS OF OR FROM IRON, COPPER, OR BRASS, OR IRON
SHEARINGS, FOR SHIPS OR OTHER PURPOSES, UPON A NEW PRINCIPLE," and which
Invention would be of public utility, he therefore prayed that His said
Majesty would be pleased to grant to him, the said John Butler, his exors,
adñiors, and assigns, Ilis Majestie's Royal Letters Patent for the sole
making and vending the said bolts and rods, and the exercise and benefit of
the said Invention, for the term of fourteen years; and His Majesty did there-
fore, by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Fourth day of March, in the twenty-sixth year of
His reign, give and grant unto him, the said John Butler, His especial licence,
full power, sole priviledge and authority, that he, the said John Butler, his
exors, adiiors, and assigns, and every of them, by bimself and themselves,
or by his and their deputy or deputies, servants or agents, or such others as
the said John Butler, his exors, adiñors, 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 said Invention within that part of Great Britain called

page_text: England, the Dominion of Wales, and Town of Berwick-upon-Tweed; to have,
hold, exercise, and enjoy the said licence, powers, privileges, and advantages
therein-before granted unto the said John Butler, his exors, aditors, and
assigns, for and during and unto the full end and term of fourteen years from the
date of the said Letters Patent next and immediately ensuing, and fully to be
compleat and ended, according to the form of the Statute in such case made
and provided; in which said Letters Patent there is contained a proviso that if
the said John Butler should 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 to cause the same to
be inrolled in His Majestie's High Court of Chancery within one calendar
month next and immediately after the date of the said recited Letters Patent,
that then the said Letters Patent, and all liberties and advantages whatso-
ever thereby granted, should utterly cease, determine, and become void, any-
thing therein-before contained to the contrary thereof in anywise notwith-
standing, as in and by the said Letters Patent, reference to the same being
had, may more fully and at large appear.
NOW KNOW YE, that in pursuance of and in compliance with the said
proviso, he, the said John Butler, doth hereby describe and ascertain the
nature of his said Invention, and in what manner the same is to be per-
formed, as follows; that is to say:
There must be two reverberatory air furnaces provided, heated with pitt
coals, one capable of producing a wielding heat, the other a more moderate
heat; and a pair of cast-iron rolls, fixed in the same manner as blackplate
rolls are, about six or seven feet distance from the furnaces, and which rolls
are to be turned or driven by water, steam, or any other power. In these
rolls round or circular groves of different dimensions must be cut, from three
inches down to the smallest rod required. The shearings of iron or other
mettal must be tied up with iron or other metal bands in bundles, something
larger than the largest groove, and put into the wielding furnace, where they
are to remain until a welding heat is obtained, and then taken out and run
through the largest groove twice or oftner, untill a bolt is formed, and then
through the next smaller grooves while the heat continues, observing to turn
the bolt a different side up every time it is passed through the rolls. The
bolts are then put into the second furnace, and moderately heated, and run
through the yet smaller grooves untill they are reduced to the size required.
Bar iron, brass, or copper are only put into the furnace which gives the
moderate heat, and run through such of the grooves as are nearest the size of
the picce to be rolled and reduced, as above described for shearings. Bolts or

page_text: barrs of metal, of a square, flat, or other form, may be made by making the
grooves of the shape required, instead of round or circular.
In witness whereof, the said John Butler hath hereunto set his hand
and seal, the Fifteenth day of March, in the twenty-sixth year of
the reign of our Sovereign Lord George the Third, by the grace of
God of Great Britain, France, and Ireland King, Defender of the
Faith, and so forth, and in the year of our Lord One thousand seven
hundred and eighty-six.
AND BE IT REMEMBERED, that on the Fifteenth day of March, in
the year of our Lord 1786, the aforesaid John Butler came before our said
Lord the King in His Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stampt according to the
tenor of the Statutes made for that purpose.
Inrolled the Twenty-ninth day of March, in the year of our Lord One
thousand seven hundred and eighty-six.
