Year: 1834

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
CRANE, of Wolverhampton, in the County of Stallord, Merchant, and JOHN
YOUNG, of the same place, Patent Lock Manufacturer, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Royal Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Twentieth day of March, in the fourth year of
His reign, and in the year of our Lord One thousand eight hundred and
thirty-four, did, for Himself, His heirs and successors, give and grant
unto us, the said Henry Crane and John Young, His especial licence,
solo privilege and authority, that we, the said Henry Crane and John
Young, our executors, administrators, and assigns, or such others as we, the
said Henry Crane and John Young, our executors, administrators, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein mentioned, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, our Invention of "CERTAIN IMPROVEMENTS IN
MAKING OR MANUFACTURING AND FORMING OF IRON FOR HOOPS OF CASES AND OTHER
PURPOSES;" in which said Letters Patent is contained a proviso that we, the
said Henry Crane and John Young (or one of us), shall cause a particular
description of the nature of, the said Invention, and in what manner the
same is to be performed, to be inrolled in His said Majesty's High Court
of Chancery within six calendar months next and immediately after the

page_text: date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Henry Crane and John Young, do hereby declare that the nature of our said
Invention, and in what manner the same is to be performed, is particularly
described and ascertained in and by the following description thereof (that
is to say):-
Our Improvements in the Making or Manufacturing and Forming of Iron
for Hoops for Casks and other Purposes consists in giving to the narrow strip
of hoop iron a curved figure, that is, bending the strip of iron from the usual
straight form in which they are delivered by the ordinary operation of rolling
into such a curve suited to the diameter of the barrel round which the hoops are
intended to bind, as will enable them, when formed, to lay close to the conical
or eliptical surface of the barrel. This is effected by peculiar method of
acting upon the strips of iron by means of rollers, in order that such required
length of iron, when cut off and bent round into the circular hoop shape, may be
formed slightly tapering or as the pustrums of cones. The method by which
we effect this is by drawing out the bar or rod of iron by rolling in the first
instance in its heated state in the usual way until it has been reduced to
nearly the required thickness; we then set the rollers so that their axles
incline at a slight angle from the true parallelism, by which means the peri-
pheries of the rollers will be nearer together at one end than at the other; and
the strips of iron, being then passed between these inclined rollers, will be
necessarily compressed or formed on one edge thicker than at the other edge,
that is, of a wedge shape, if cut in a transverse section. This may be done by
relieving the screws which confine the axle at one end and tightening them at
tho other end, or the same might be effected by making the grooves and ribs
of the two rollers inclined to each other instead of parallel. When the strip
of iron has assumed this wedge shape in its transverse sectional figures, we
then pass it in its heated state between a pair of parallel rollers, which, by
pressing principally the thicker part of the substance of the strip of iron,
causes the thick part to 'expand and elongate more than the thinner part of
the strip, and, consequently, to extend or elongate the strip more on one edge
than on the other. This mode of operating will cause the strip of iron as it
is discharged from the parallel rollers in the last instance to assume the form
of a regular curve, and which curve may be varied to suit any required
diameter and inclination of the surface of the cask or barrel by varying the
inclination of the rollers or the bevel of the groove by which the strips are
compressed into the wedge shape, that is, thicker on one edge than on the other;

page_text: and in order to prevent the strip of iron from bending into irregular curves as
it passes in its heated state from the rollers, we have found it useful to placo
a curved guide or conductor near the rollers, which will enable the workman,
as he draws out the strip of iron from the rollers, to preserve its desired figure
with great accuracy.
Lastly, we wish it to be observed, that as the rolling of iron for the purpose
of bringing it into thin and narrow strips for the manufacture of hoops is not
new, of course that process is not to be considered as claimed by us; but the
taking of strips of iron previously made thicker on one edge than on the
other, and passing them between parallel rollers for the purpose of expanding
the metal on one side of the strip more than on the other side, and thereby
giving to the strip a curved figure as it is discharged from the rollers, being
to the best of our knowledge and belief new and never before employed by
any other person or persons in the manufacturing of hoops, we claim that
mode of operating as our Invention, and forming the essential feature of our
present Patent right.
In witness whereof, we, the said Henry Crane and John Young, have
hereunto set our hands and seals, this Seventeenth day of September,
in the year of our Lord One thousand eight hundred and thirty-four.
HENRY (L.S.) CRANE.
JOHN (L.S.) YOUNG.
AND BE IT REMEMBERED, that on the Seventeenth day of September,
in the fifth year of the reign of His Majesty King William the Fourth,
the said Henry Crane and John Young came before our said Lord the
King in His Chancery, and acknowledged the Instrument aforesaid, and
all and every thing therein contained and specified, in form above written.
And also the Instrument aforesaid was stamped according to the tenor of the
Statute made in the fifty-fifth year of the reign of His late Majesty King
George the Third.
