Year: 1855

page_text: LETTERS PATENT to Rogers Ruding, of 51, Bunhill Row, in the City of
⚫ London, for the Invention of "AN IMPROVEMENT IN PRINTING SILKS AND
OTHER WOVEN FABRICS. WITH GOLD AND OTHER METAL LEAF OR POWDER."
..
PROVISIONAL SPECIFICATION left by the said Rogers Ruding at the
Office of the Commissioners of Patents, with his Petition, on the 11th
December 1855.
I, ROGERS RUDING, of 51, Bunhill Row, in the City of London; do hereby
declare the nature of the Invention for "AN IMPROVEMENT IN PRINTING SILKS
AND OTHER WOVEN FABRICS WITH GOLD AND OTHER METAL LEAF OR POWDER" to be
as follows:
This Invention consists of employing shell-lac in a refined and powdered
state, together with a heated printing surface, for printing silks and other
woven fabrics with gold and other metal leaf or powder. For this purpose I
take the dried powder of shell lac, obtained by-precipitating it from a solution:
This powder is dusted evenly over the surface which is to be printed with gold
or other metal leaf, or it might be metal powder, which is to be spread over
the shell lac, and then a heated printing surface is to be applied, by which the
metal will be caused to adhere to those parts where the printing impression is
made, by reason of the melting of the shell lac, whilst the 'unmelted shell lac
and the metal which is over other parts of the fabric may be brushed; off:...

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROGERS
RUDING, of 51, Bunhill, Row, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of December, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Rogers Ruding, Her special licence that I, the said Rogers Ruding,
my executors, administrators, and assigns, or such others as I, the said
Rogers Ruding, 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 "AN IMPROVEMENT IN
PRINTING SILKS AND OTHER WOVEN FABRICS WITH GOLD AND OTHER METAL LEAF OR
POWDER," upon the condition (amongst others) that I, the said Rogers Ruding,
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.
:
י
NOW KNOW YE, that I, the said Rogers Ruding, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention consists of employing shell lac in a refined and powdered
state, together with a heated printing surface, for printing silks and other
woven fabrics with gold and other metal leaf or powder. For this purpose
I take the dried powder of shell lac, obtained by precipitating it from a
solution. This powder is dusted evenly over the surface which is to be printed
with gold, or other metal leaf, or it might be metal powder, which is to be
spread over the shell lac, and then a heated printing surface is to be applied,
by which the metal will be caused to adhere, to those parts where the printing
impression is made, by reason of the melting of the shell lac, whilst the

page_text: unmelted shell lac and the metal which is over other parts of the fabric may
be brushed off.
Having thus stated the nature of my said Invention, I will proceed to
describe more fully the manner of performing the same. The shell lac having
been dissolved in spirit and precipitated, as is well understood, and dried, I
employ the purified gum in the following manner:-The dried powdered gum
is dusted evenly on the parts of the silks or other woven fabric where the
device is to be produced; the gold or other metal leaf is placed thereon, and a
heated tool or metal surface, having thereon the desired device or pattern, is to
be pressed on to the leaf; the heat will melt the gum below, and the metal
leaf will adhere at those parts where the pressure of the heated surface comes,
whilst the other parts of the gum will remain unmelted, and may be removed,
together with the excess of metal leaf. I would state, that in place of gold or
other metal leaf being used, gold or other metal powder may be employed, and
placed on the fabric over the powder of the gum, and by means of the heated
tool or surface a like result will be obtained. The object of the Invention, it
will be seen, is, that the gum should when on the fabric be in a dry state, so
that when the gold or other metal leaf or powder is laid on it shall not adhere,
and shall only be made to do so in those parts where a suitable heated tool or
surface is pressed; and I have found that a thin and clear solution of the gum
may be spread all over the surface of the silk or other woven fabric, which
will only act slightly to stiffen the fabric, and gold or other metal leaf or
powder may be made to adhere thereto in pattern in those places where a
heated tool or pattern is impressed, as above explained; for it will be found
that the gold or other metal leaf or powder laid on such prepared fabrics will
only adhere at the parts where the impression is made, the other parts of the
gum not melting.
In witness whereof, I, the said Rogers Ruding, have hereunto set my.
hand and seal, this Tenth day of June, in the year of our Lord One
thousand eight hundred and fifty-six.
Witness,
JNO. ALCOCK.
ROGERS RUDING. (L.S.)
