page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
MARTIN, of Morriston, in the County of Glamorgan, Gentleman, send
greeting.
WHEREAS His present most Excellent Majesty King George the Third,
in and by His Letters Patent under His Great Seal of the United Kingdom
of Great Britain and Ireland, bearing date at Westminster, the Twenty-third
day of June, in the forty-fourth year of His reign, for Himself, His
heirs and successors, did give and grant unto me, the said Edward
Martin, my executors, administrators, and assigns, His special licence, full
power, sole privilege and authority, that I, the said Edward Martin, my
executors, administrators, and assigns, and every of them, by myself and
themselves, or by my and their deputy or deputies, servants or agents, or such
others as I, the said Edward Martin, my executors, administrators, or
assigns, should at any time agree with, and no others, from time to time
and at all times hereafter during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within that part
of His said Majesty's United Kingdom called England, His Dominion of
Wales, and the Town of Berwick-upon-Tweed, my Invention for "MAKING
OF PIG AND CAST IRON OF EVERY DESCRIPTION, FROM IRON STONE, IRON MINE,
AND IRON ORE, AND OF RE-MELTING, PREPARING, AND REFINING OF PIG AND
CAST IRON OF EVERY SORT, AND FOR THE MAKING OF SUCH PIG AND CAST IRON
INTO WROUGHT OR BAR IRON, BY USING RAW STONE, COAL, AND CULM, TO BE

page_text: WORKED AND MADE BY BLAST;" in which said Letters Patent there is contained a
proviso obliging me, the said Edward Martin, by an instrument in writing
under my hand and seal, particularly to describe and ascertain the nature
of my said Invention, and in what manner the same is to be performed,
and to cause the same to be inrolled in His said Majesty's High Court
of Chancery within one calendar month next and immediately after the date
of the said recited Letters Patent, as in and by the same, relation being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Edward Martin, do hereby describe and ascertain the nature of my said
Invention, and the manner in which the same is to be performed, and the
method I use to make stone, coal, and culm to stand the blast, as follows,
that is to say:-
To light the fire in the furnace finery or hearth with free burning wood,
and as soon as the wood is sufficiently ignited then to put on small quantities
of raw stone, coal, or culm, free of dust (broken into the size of a common
hen's egg), to continue to feed the furnace finery or hearth with raw stone,
coal, or culm till it is quite full of vivid fire before any blast is introduced;
then (in making pig or cast iron) charge the furnace in the common way
with due proportions of raw stone, coal, or culm, clear of dust (instead of
coke or charcoal), with iron stone, iron mine, or iron ore and limestone; then
to introduce the blast in a very gentle manner for the first twelve hours;
then to increase the blast gradually day after day for the first week of blowing,
extent
till the furnace is sufficiently hot and burthened, and then to blow to any
the machinery or the furnace is capable of bearing; and by keeping the furnace
regularly and properly fed with materials, and by keeping up a sufficient blast,
the process will be compleated.
And in re-melting, preparing, and refining of pig and cast iron of
every sort, and for making such pig and cast iron into wrought or bar
iron, the foregoing method of lighting and feeding the hearth or finery
till it is full of vivid stone, coal, or culm must be pursued before the
finery or hearth is charged with metal, or the blast introduced, then by
charging with metal and feeding the finery or hearth with raw stone, coal, or
culm (instead of coke or charcoal, and by introducing the blast in the
common way, the wish'd-for success will be produced.
In witness whereof, I, the said Edward Martin, have hereunto set my
hand and seal, the Twenty-third day of June, in the year of ou
Lord Que thousand eight hundred and four.
EDWD MARTIN. (L.S.)
