Sealed the 18th December 1852, and dated the 1st November 1852.
PROVISIONAL SPECIFICATION left by the said David Thomson
at the Office of the Commissioners of Patents, with his Petition,
on the 1st November 1852.
I, DAVID THOMSON, of Dundee, in the County of Forfar, Manu-
facturer, do hereby declare the nature of the said Invention for "In-
PROVEMENTS IN THE MANUFACTURE OF CARPETS" to be as follows:-
This Invention relates to the improvement of carpet fabrics, floor
cloths, and other goods of a similar class when manufactured from
jute, in as far as regards the brilliancy and permanency of the orna-
menting colours thereof. Hitherto jute fabrics of such classes have
been made from yarns ornamented with what are termed "fancy dyed
colours," and as such colours are not permanent the goods very soon
loose the most of their colour on exposure to atmospheric influences
and the sun's rays. Now according to this improvement the jute yarns
are entirely ornamented with "fast dyed colours," the ornamentation

filed by the said David Thomson in the Great Seal Patent
Office on the 30th April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
DAVID THOMSON, of Dundee, in the County of Forfar, North Britain,
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of November, in the year
of our Lord 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 David Thomson, Her special licence
that I, the said David Thomson, my executors, administrators, and
assigns, or such others as I, the said David Thomson, 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 "IMPROVEMENTS
IN THE MANUFACTURE OF CARPETS," upon the condition (amongst others)
that I, the said David Thomson, 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 1, the said David Thomson, 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, that is to say:
My said Invention relates to the production of a superior class of
carpet fabrics, floor cloths, and other goods of a similar nature from the

page_text: fibrous material technically known as jute, in as far as regards the
brilliancy, general effect, and permanence of the ornamenting colours
thereof. Hitherto jute fabrics of the class to which I have referred
have always been made from yarns ornamented with what are terined
"fancy dyed colours," and as such colours are not permanent the goods
very soon lose the most of their colour when exposed to atmospheric
influences and the rays of the sun. Now according to my improve-
ments I ornament the jute yarns entirely and solely with "fast dyed
colours," the range of ornamentation being confined to such colours as
are really fast or capable of withstanding the deteriorating effects of
time and exposure, so that the goods manufactured from such yarns
retain their original brilliancy after continued use, whilst the patterns
or devices produced by such colours are equally as effective as those on
the best woollen fabrics.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used
or carried into effect, I may observe, in conclusion, that I do not confine
or restrict myself to the precise details or arrangements which I have
had occasion to describe or refer to, as many variations may be made
therefrom without deviating from the principles or main features of my
Invention; but what I consider to be novel and original, and therefore
claim as the Invention secured to me by the herein-before in part
recited Letters Patent, is,-
First, the system or mode of ornamenting jute carpet and other
fabrics of a like class solely by means of fast dyed colours.
Second, the system or mode of producing jute fabrics of superior
appearance by restricting the ornamental colours thereof to such as
are fast.
In witness whereof, I, the said David Thomson, have hereunto set
my hand and seal, this Twenty-eighth day of April, in the year
of our Lord One thousand eight hundred and fifty-three.
DAVID THOMSON. (L.B.)
