IMPROVEMENTS IN MAKING SOLID IRON SCALES WITH BOLSTERS FOR ALL KINDS OF SPRING KNIVES
Year: 1865

page_text: LETTERS PATENT to Arthur Davy, of Spring Hill, Sheffield, in the
County of York, for the Invention of "IMPROVEMENTS IN MAKING SOLID
IRON SCALES WITH BOLSTERS FOR ALL KINDS OF SPRING KNIVES."
Sealed the 25th August 1865, and dated the 28th February 1865.
PROVISIONAL SPECIFICATION left by the said Arthur Davy at the Office
of the Commissioners of Patents, with his Petition, on the 28th February
1865.
I, ARTHUR DAVY, of Spring Hill, Sheffield, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN MAKING
SOLID IRON SCALES WITH BOLSTERS FOR ALL KINDS OF SPRING KNIVES," to be
as follows:-
I take a rod of iron of the required size, breadth, or strength, and after it
has been made sufficiently hot in a furnace (or such other means as are
usually employed) I place the hot iron between a pair of revolving rolls, one
of them having one or more transverse grooves, of any size that may be
required, cut in it either partially across or the whole length of the rolls, and
at such distances apart as the length of the web may be required; the plain
part or surface of the rolls press out and flatten down the iron sufficiently thin
and broad to form the web or scale, the substance required to form the bolster
being forced into the grooves; I then separate the scales by cutting or other
means, and stamp or press the substance left by the grooves in dies or prints
into any desired shape or ornamental form.

page_text: The object of this Invention is to produce solid iron scales more smooth and
perfect, and better adapted to receive the covering, such as ivory, bone, stag,
and such like materials; the surface being smooth, the covering will fit more
closely than those wrought by band, greater expedition also being acquired,
and at a less cost than by any other method at present in use.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Arthur Davy in the Great Seal Patent Office on the
28th August 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARTHUR
DAVY, of Spring Hill, Sheffield, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of February, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Arthur Davy, Her special licence that I, the said Arthur
Davy, my executors, administrators, and assigns, or such others as I, the
said Arthur Davy, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN MAKING SOLID IRON SCALES WITH BOLSTERS FOR ALL KINDS OF SPRING
KNIVES," upon the condition (amongst others) that I, the said Arthur Davy,
my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer
tain the nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Arthur Davy, do hereby declare the
nature of my said Invention, and in what manner. the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
I take a rod of iron of the required size, breadth, or strength, and after it
has been made sufficiently hot in a furnace (or such other means as are
usually employed) I place the hot iron between a pair of revolving rolls, one

page_text: of them having one or more transverse grooves, plain or ornamental, of any
size that may be required, cut or cast in it, either partially across or the
whole length of the rolls, and at such distances apart as the length of the rolls
may be required; the plain part or surface of the rolls press out and flatten
down the iron sufficiently thin and broad to form the web or scale, the
substance required to form the bolster being forced into the grooves; I then
separate the scales by cutting or other means, and stamp or press the
substance left by the grooves in dies or prints into any desired shape or
ornamental form. .
The object of this Invention is to produce solid iron scales more smooth and
perfect, and better adapted to receive the covering, such as ivory, stag-bone,
&c.; the surface being smooth the covering will fit more closely than those
wrought by hand, greater expedition also being acquired than by any other
method at present in use.
Having now described the nature of my Invention, and the manner in which
the same may be performed, I declare that what I claim and desire to be
secured by the herein-before in part recited Letters Patent is, the improve-
ments in making solid iron scales with bolsters for all kinds of spring knives,
as herein-before described, or any mere modification thereof.
In witness whereof, I, the said Arthur Davy, have hereunto set my hand
and seal, this Twenty-eighth day of August, in the year of our Lord
One thousand eight hundred and sixty-five.
