Year: 1852

page_text: LETTERS PATENT to John Jones, of Sheffield, in the County of
York, Manufacturer, for the Invention of "IMPROVEMENTS IN
HANDLES FAD KING RAZODS AND OTHER LIFE INSTRUMENTO
PROVISIONAL SPECIFICATION left by the said John Jones at the
Office of the Commissioners of Patents, with his Petition, on the
19th October 1852.
I, JOHN JONES, do hereby declare the nature of the said Invention
to be for "IMPROVEMENTS IN HANDLES POR KNIVES, RAZORS, AND OTHER LIKE
INSTRUMENTS."
My Invention consist in produceing imitation ivory by coating
wood, metal, or any other substance in the form of handles for cutting
instruments with a transparent composition so as to imitate the grain
and colour of ivory; the details will be stated at length in the Complete
Specification.
ADDITION TO PROVISIONAL SPECIFICATION.
I, JOHN JONES, do hereby declare the nature of the said Invention to
be for "IMPROVEMENT IN HANDLES FOR KNIVES, RAZORS, AND OTHER LIKE
: INSTRUMENTS."
My Invention consists in coating light coloured wood, or any other
Substance applicable to the above. I purpose covering them with a

page_text: transparent colour, such as copal varnish, being mixed so as to imitate
ivory. The handles so covered, the grain is seen through the transparent
varnish, which gives the appearance of real ivory.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Jones in the Great Seal Patent Office
on the 19th April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,'
JOHN JONES, of Sheffield, in the County of York, Manufacturer, send
greeting.
15.1
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of October, in the year
of our Tord One, thousand eight hundred and fifty-two, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Jones, Her special licence
that I, the said John Jones, my executors, administrators; and assigns;
or such others as 1, the said John Jones, my executors, administra-
tors, and assigns, should at any time agree with, and no others, from
time to time and, at all times thereafter during, the term therein ex-
pressed, 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 "IMPROVEMENTS
IN HANDLES FOR KNIVES, RAZORS, AND OTHER LIKE INSTRUMENTS," upon
the condition (amongst others). that I, the said John Jones, by an
instrument in writing. under my hand and seal, should particularly
describe and ascertain 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 John Jones, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement:

page_text: The handles are enamelled thus (supposing them completed in the
making department):-First, they receive a coat of linseed oil, both
externally and in the hole of the handle, so as to keep moisture from
entering the wood (if made of that material). Second, the handles get
a.coat of color composed of best flake white, fine ground, with a little
turpentine, and mixed up with equal 'quantities of best copal varnish
and turpentine till the mixture is easily put on with a camel hair brush,
but not so thin as to run; if the varnish is of a hard nature we mix a
little oil to keep,from cracking. If the handles be made of box wood
or other light colored wood, the grain of, the wood is seen through the
composition, which gives.an appearance of real ivory, both as regards
the grain and colour. Third, the handles are then thoroughly dried in a
stove heated to from 70 to 80 degrees. Thus far I produce an imita-
tion of transparent ivory. Fourth, another coat of the same mixture,
and again dried, gives the appearance of white ivory without the grain.
Fifth, a coat of pure copal varnish, and again dried. Sixth. a coat of
the following compositions, and dried:-1, copal varnish; 2, as much
flake white finely ground as serves to destroy the yellow colour of the
varnish; 3, as much turpentine as brings back the mixture to the same
thickness as pure varnish. Seventh, another coat of the same, and again
dried. Eighth, smoothed down with sand paper. Ninth, a coat of pure
copal varnish, and dried for three or four days in a stove from 70 to 80
degrees. Tenth, smoothed down with the finest portion of the best water
ground flint with water, and applied with a cloth. Eleventh, polished
with the finest portion of the best rotten stone mixed with water, and
applied with a-cloth. Twelfth, finishing polish given with the hand,
and a very minute quantity of olive oil.
The latest and best process I have done them thus:-Coat of linseed
oil, three coats of No. 2 mixture, three coats of pure copal varnish, then
sand papered, one coat of pure copal varnish, and then polished.
The difference of this last process and the former is, that in the
former, of No. 6 composition, two coats are introduced instead of three
coats of pure copal varnish in the latter, to the very great improvement
of the solid appearance of the handles; and also in the former process
there is one coat of pure copal introduced between the colour coats,

page_text: this being done with the intention that in case of the top coats wearing
through till they come to this coat of pure varnish the handles would
he very little hurt in appearance.
In witness whereof, I, the said John Jones, have hereunto set my
hand and seal, this Eighteenth day of April, in the year of our
Lord One thousand eight hundred and fifty-three.
JOIN JONES. (L. s.)
