page_text: LETTERS PATENT to John Thomas Griffiths, of New Basford, in the
County of Nottingham, Lace Manufacturer, for the Invention of
"IMPROVEMENTS IN THE MANUFACTURE AND ORNAMENTING OF LACE."
PROVISIONAL SPECIFICATION left by the said John Thomas Griffiths
at the Office of the Commissioners of Patents, with his Petition, on the
28th December 1857.
I, JOHN THOMAS GRIFFITHS, of New Basford, in the County of Nottingham,
Lace Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE AND ORNAMENTING OF LACE," to be as
follows:-
My Invention consists, first, in a new mode of laying certain threads,
denominated by the trade thick threads and gimp threads, by working in the
said threads between the warp threads at the same time as the fancy and net
work of the lace are being made.
My Invention also consists in ornamenting lace by causing figures or devices
of any desired color, previously prepared by being cut or stamped in velvet,
cloth, terry velvet, or other fabric, to adhere to both sides of the lace and back
to back in such manner that the said figures cannot be detached from the
lace without tearing the same."

by the said John Thomas Griffiths in the Great Seal Patent Office on
the 28th June 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
THOMAS GRIFFITHS, of New Basford, in the County of Nottingham, Lace
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of December, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Thomas Griffiths, Her special licence that I, the said John
Thomas Griffiths, my exécutors, administrators, and assigns, or such others as
I, the said John Thomas Griffiths, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter 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 THE MANUFACTURE AND ORNAMENTING OF LACE," upon the condition
(amongst others) that I, the said John Thomas Griffiths, my executors or
administrators, by an instrument in writing under my, or their, or one of
their hands and seals, 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 Thomas Griffiths, 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 thereof, that is to say: -
My Invention consists, first, in a new mode of laying certain threads, deno-
minated by the trade thick threads and gimp threads, by working in the
said threads between the warp threads at the same time as the fancy and net
work of the lace are being made.
In carrying this part of my Invention into effect, I move the thick threads
and the gimp threads when the carriages or bobbin threads are at the back of
the fine threads or warp threads, or, in other words, when the carriages are in
the back motion. Both the thick threads and the gimp threads are fastened
in the work or lace by means of the fine threads or warp threads which work
in front of the thick threads and gimp threads. When the warp is single, I

page_text: take every alternate warp thread, and work it in front of the thick threads
and gimp threads. When the warp is double, I take every fourth thread only,
and work it in front of the thick threads and gimp threads. The fine threads
or warp threads are worked in by means of stump bars or guide bars of the
ordinary kind. In some cases I produce a good effect in the finished lace by
introducing a cotton, flax, or any other suitable thread between two silk gimp
threads, in such manner that the silk threads shall cover the cotton, flax,
or other thread, the covered thick thread being worked into the lace as before
described.
My Invention consists, secondly, in ornamenting lace by causing figures or.
devices of any desired color, previously prepared by being cut or stamped out
of velvet, cloth, terry velvet, or other fabric, to adhere to both sides of the
lace, and back to back, in such manner that the said figures cannot be
detached from the lace without tearing the same. In carrying this part of
my Invention into effect I employ any suitable adhesive substance.
And having now described the nature of the said Invention, and in what
manner the same is to be informed, I declare that I claim,-
First, the mode of laying thick threads and gimp threads between the
warp threads, as herein-before described.
Second, the method of ornamenting lace by causing figures or devices of
any desired color, formed of velvet, cloth, terry velvet, or other fabric, to
adhere to both sides of the lace and back to back, as herein-before described.
In witness whereof, I, the said John Thomas Griffiths, have hereunto
set my hand and seal, this Twenty-eight day of June, One thousand
eight hundred and fifty-eight.
JOHN THOMAS GRIFFITHS. (L.S.)
