TO ALL TO WHOM THESE. PRESENTS SHALL COME, I, ARNOLD
WILDE, of Sheffield, in the County of York, Saw Maker; 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 West-
minster, the Nineteenth day of January, in the thirty-fifth year of His reign,
did give and grant unto me, the said Arnold Wilde, my exors, admors, and
assigns, His especial licence, full power, sole priviledge and authority, that
I, the said Arnold Wilde, my.exors, adñññors, and. assigns, and every of them,
from time to time and at all times thenafter.during the term of fourteen-years
therein expressed, should and lawfully, might make, use, exercise, and vend
my Invention of "MAKING AND MANUFACTURING OF ALL SORTS OF PLANE IRONS,
SCYTHES, SICKLES, DDAWING KNIVES, HAY KNIVES, AND ALL OTHER KINDS OF
EDGE TOOLS, FROM A PREPERATION OF CAST STEEL AND IRON UNITED AND INCOR-
PORATED TOGETHER BY MEANS OF FIRE," within England, Wales, and the Town
of Berwick-upon-Tweed; in which said Letters Patent there is contained a
proviso that if I, the said Arnold Wilde, shall not particularly describe and
ascertain the nature of my said Invention, in what manner the same is
to be performed, by an instrument in writing under my hand and seal, and
cause the same to be inrolled in the High Court of Chancery within one
calendar month next and immediately after the date of the said Letters

page_text: Patout; that then the said Letters Patent and all liberties and advantages
whatsoever thereby granted, should utterly cease, determine, and become void,
as by the said Letters Patent, on reference being thereunto had, will more
fully and at large appear.
NOW KNOW YE, THEREFORE, that I, the said Arnold Wilde, do hereby
declare that my said Invention of Making and Manufacturing of all Sorts of
Plane Irons, Scythes, Sickles, Drawing Knives, Hay Knives, and all other
Kinds of Edge Tools, from a Preparation of Cast Steel and Iron United
and Incorporated together by Means of Fire, is particularly described and
ascertained in manner following (that is to say):-
Take a mould of cast iron or other fit material, of a dimension that will
best suit tho size of the article intended to be manufactured; then take a
piece of wrought iron and prepare it by heating in a fire, and hammering it,
or in any other manner you may think proper, to the size you want it; then
fix the iron in the mould (loaving a sufficient vacancy to receive the cast
steel in the fluid state) in such a direction so as that when the cast steel is
poured into the mould the iron may be either in the middle or the centre of
the cast steel, or on one or both sides of the cast steel, or in such other
direction as may best suit the purpose for which the iron and cast steel when
incorporated shall be wanted; then put the crucible or pot into the furnace:
when the crucible or pot is hot put steel into it, then fix on the lid to the
crucible or pot, and continue it in the furnace or fire till the steel becomes
fluid when you suppose the steel to be nearly in a fluid state, take your picco
of iron which you intend to incorporate with the cast steel, put it into a fire
and heat it to what is usually called a welding heat; then take the iron out of
the fire, clean it from any scale or dirt, and fix it in the mould in the like
direction you had before fitted it, and take care that your steel be now in a
fluid state; and immediately on your taking the iron out of the fire take the
crucible or pot containing the melted steel from the furnace or fire, and
immediately after the iron thus heated shall be fitted in the mould, pour or
turn the fluid steel into the space or vacancy left in the mould to receive the
same; which will incorporate with the iron and become one solid mass or
body of cast steel and iron united.
To make all sorts of plane irons, scythes, sickles, drawing knives, hay
knives, and all other kinds of edge tools of cast steel and iron to be united as
herein-before mentioned, take a picco of the cast steel and iron united as
before mentioned; forge, roll, slitt, or tilt it in such way as is proper for any
or either of the articles intended to be manufactured; then the article may bo

most convenient.
In witness whereof, I have hereunto set my hand and seal, the Sixteenth
day of February, in the year of our Lord One thousand seven hundred
and ninety-five.
