CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF HELVES
Year: 1851

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY BROWN, of Ward's End Steel Works, near Sheffield, in the County of
York, Steel Roller, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Sixth day of May; One
thousand eight hundred and fifty-one, in the fourteenth year of Her reign, did,
for Herself,-Her-heirs-and-successors,-give- and grant unto me,_the_said.
William Henry Brown, my exors, adñors, and assigns, Her especial licence, full
power, sole privilege and authority, that I, the said William Henry Brown, my
exors, admors, and assigns, or such others as I, the said William Henry Brown,
my exors, adñors, 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 expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "CERTAIN
IMPROVEMENTS IN THE MANUFACTURE OF HELVES;" in which said Letters Patent.
there is contained a proviso, that I, the said William Henry Brown, shall
cause a particular description of 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 seal, to be inrolled in Her Majesty's High Court of Chancery
within six calendar months next and immediately after the 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, I, the said
William Henry Brown, do hereby declare the nature of my Invention, and

page_text: the manner in which the same is to be performed, is particularly described
and ascertained in and by the following statement thereof, reference being
had to the Drawings hereunto annexed, and to the figures and letters marked
thereon, that is to say:-
The helves ordinarily in use are made of wood (generally ash) bound with
iron hoops, as shewn in Sheet I. Such wooden helves are subject to many
disadvantages, amongst others, the heating of the wood and the consequent
necessity of stopping the action of the helve to cool the wood; helves of solid
wrought iron and solid metal have been tried, but they have failed, the absence
of the requisite elasticity and other objections having led to their abandon-
ment. Now, I. have discovered that hollow helves manufactured of boiler
plate, or helves of boiler plate in combination with wood or hollow metal
helves, as shewn in the accompanying Drawings, have the requisite elasticity
for the working of the helve and hammering of the steel in the usual manner,
and are in a great measure or entirely free from the defects to which the
wooden helves are subject; these improved helves may be of similar dimen-
sions to the wooden helves heretofore in use. A hollow helve of boiler plate
may be constructed as shewn in Sheet I., a wooden plug being inserted at
each end, so as to sustain the sides and form of the helves against the pressure
of the hammer head and tail loop when fastened on in the usual manner by
wedges.
Sheet I. of the accompanying Drawings shews in detail the construction of
the helves of boiler plate; and Sheet II. shews in detail other constructions
of helves of boiler plate in combination with wood and hollow metal helves;
the details of such helves may be varied according to the peculiar construction
adopted. The axes about which the helve moves may be connected with the
helve as heretofore, as shewn in Sheet I., or it may be made to form part of
the helve itself.
Having now described the nature of my said Invention, and in what
manner the same is to be performed, I wish it to be understood that I claim
as the Invention intended to be secured by the said Letters Patent, first, the
manufacture of hollow helves of boiler plate, as shewn in Sheet I.; secondly,
the manufacture of helves of boiler plates in combination with wood, as
shewn in Sheet II.; thirdly, the manufacture of hollow metal helves, as above
described.
In witness whereof, I, the said William Henry Brown, have hereunto set
my hand and seal, this Sixth day of November, in the year of our
Lord One thousand eight hundred and fifty-one.
W. H. (L.S.) BROWN.
