AN IMPROVED PLAN OR METHOD OF TURNING ROLLS AND OF ROLLING GUN AND PISTOL BARRELS PREVIOUS TO WELDING
Year: 1814

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
GEORGE HEYWOOD, of Brockmoor Iron Works, near Stourbridge, in the
Parish of Kingswinford, in the County of Stafford, Ironmonger, send
greeting.
WHEREAS His most Excellent Majesty King George the Third
did, by His Letters Patent under the Great Seal of the United King-
dom of Great Britain and Ireland, bearing date at Westminster, the
Seventh day of June, in the fifty-fourth year of His reign, give and
grant unto me, the said George Heywood, my exors, adors, and
assigns, His especial licence, full power, sole privilege and authority,
that. I, the said George Heywood, my exors, adiñors, and assigns,
should and lawfully might, during the term of years therein mentioned,
make, use, exercise, and vend, within England, Wales, and the Town
of Berwick upon Tweed, my Invention of "AN IMPROVED PLAN OR
METHOD OF TURNING ROLLS AND OF ROLLING GUN AND PISTOL BARRELS
PREVIOUS TO WELDING;" in which said Letters Patent there is contained

page_text: a proviso, that if I, the said George Heywood, shall not particularly
describe and ascertain the nature of my said Invention, and in what
manner the same is to be performed, by an instrument in writing under
my hand and scal, and cause the same to be inrolled in His Majesty's
High Court of Chancery within six calendar months next and imme-
diately after the date of the said Letters Patent, that then the said
Letters Patent, and all liberties and advantages whatsoever thereby
granted, shall utterly cease, determine, and become void, as in and by
the same (relation being thereunto had) may more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the
said George Heywood, do hereby declare that the nature of my said
Invention, and manner in which the same is to be performed, are
particularly described and ascertained in manner following, that is
to say-
I do form or make one or more pairs of rolls of sufficient strength,
magnitude, and firmness of metal (for which good cast iron of the
quality commonly used for rolls is preferable), for the purpose of rolling
out bars or pieces of iron, and I do, as shewn or exemplified in the
Drawings hereunto annexed, duly mount or support the said pairs of
rolls with adjustments, and in connection with each other by wheel
work or other contrivance of the like nature, by means or in conse-
quence whereof the rolls of each pair shall severally be caused or
suffered to revolve together, so as in each operation, as far as may or
shall depend upon the rotation of the said rolls, the effect produced by
rolling upon any similar bar or picce of iron shall give the same figure
thereto as would have been given by the like, rolling into any other
similar bar or piece. And, moreover, I do form, fashion; or make, in
or upon the surfaces of the said rolls, or one of them in each pair
certain grooves or excavations intended to correspond with and give
the proposed figure to the convex or projecting side of any bar or piece
of iron which shall or may be rolled; and in some of the pair of rollers
I do form, fashion, or make, at or upon the surface of one of the said
rolls, certain projections or longitudinal protuberances, so adapted
respectively to certain of the grooves or excavations aforesaid as to

page_text: igure, fit for sound and accurate welding, and for the subsequent
processes of the manufacture.
In witness whereof, I, the said George Heywood, have hereunto
set my hand and seal, this Twenty-eighth day of November, in
the year of our Lord One thousand eight hundred and fourteen.
GEORGE HEYWOOD. (L.S.)
AND BE IT REMEMBERED, that on the Twenty-eighth day of
November, in the year of our Lord 1814, the aforesaid George
Heywood came before our said Lord the King, in His Chancery, and
acknowledged the Specification aforesaid, 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
Statute made for that purpose.
Inrolled the Twenty-ninth day of November, in the year of our

page_text: leave an interval between the surfaces of the said grooves or exca-
vations, and of the said projections or protuberances, which shall
correspond with the size and figure intended to be given to any bar or
piece of iron intended to be passed and rolled between the same. And,
farther, I do make the said grooves or excavations, and the said pro-
jections or protuberances, of such dimension srespectively, and at such
distances asunder in the several parts of the rotation of the rolls, as
that bars or pieces or concave portions of the iron shall be rolled or
drawn out with the duc and regular thickness, tapering, and length
which shall or may be required in the said gun and pistol barrels. And
I do further declare, that in rolling the said barrels I do avail myself.
according to the nature of the material and the well-known art of
rolling, laminating, or extending metallic bodies, of the method of
drawing or rolling by repeated actions, and not all in one; and that I
do, when according to that art it would be requisite, ignite by a low heat
or anneal my materials between the respective operations. And with
regard to the Drawings of rolls hereunto annexed, which are capable of
being considerably varied in such particulars. as. any workman compe
tent to make machinery of this, or the like nature would (without
further instruction; and merely from consideration of the work to be
done, or local or other situations or conditions to be attended to), may
readily adopt. I do further declare that in the perspective view
Fig. 1, the letters d, and e, do indicate a pair of rolls having grooves
therein, for rolling bars or pieces of iron into a taper, square form, or
frustum of a quadrangular pyramid, and that the letters a, and b, do
indicate a pair of rollers at or upon the surface of the one, of which a,
are several of the projections or protuberances aforesaid, and in or upon
the surface of the other of which b, are several of the grooves or exca-
vations aforesaid, corresponding respectively, as herein before described,
with the projections or protuberances; and that Fig. 2, and 3, do indi-
cate more plainly and in the manner of a section the spaces between
each pair of rolls. And, lastly, that I do, in the practice of my said
Invention, roll my bars or pieces of iron between the rolls d, and e, and
do afterwards pass the said rolled bars or pieces between the rolls a,
and b, and do thereby give unto the same a very correct and proper
