Year: 1875

page_text: LETTERS PATENT to Louis Ferdinand Tavernier and John Pyper
Matheson, of the Perseverance Mills, Dewsbury Road, Leeds, in
the County of York, Patent Coactile Cloth Manufacturers, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF. FELTED FABRICS
AND IN THE PRODUCTION OF MIXED COLOURS IN FELTED FABRICS BY CHEAP
AND SIMPLE PROCESSES."
PROVISIONAL SPECIFICATION left by the said Louis Ferdinand
Tavernier and John Pyper Matheson at the Office of the Com-
missioners of Patents, with their Petition, on the 30th January
1875.
We, LOUIS FERDINAND TAVERNIER, and JOHN PYPER MATHESON, of
the Perseverance Mills, Dewsbury Road, Leeds, in the County of York,
Patent Coactile Cloth Manufacturers, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF FELTED

page_text: -
FABRICS AND IN THE PRODUCTION OF MIXED COLOURS IN FELTED FABRICS BY CHEAP
AND SIMPLE PROCESSES," to be as follows:-
The objects of this Invention are improvements in the manufacture of
felted fabrics, and in the production of mixed colours in felted fabrics by
cheap and simple processes.
We combine natural dark colour wool or a dark dyed coloured wool with
a natural light colour wool, and mix the two intimately by the carding
process. The wools in the mixed state are then felted in the ordinary
manner upon a cotton or other web or length, and then dyed in any
suitable colour. The natural light colour wool partakes of the dye
'colour, and the natural dark colour or dark dyed coloured wool remains
dark. The result is to the eye a mottled or a mixed colour appearance.
The dye colour can be of any degree of brightness, say of red, brown,
blue, green, or other, which the natural light colour wool, say white,
will become stained or dyed by, but the natural dark or a dark dyed
colour wool, say black, being the deeper or stronger of the two colours,
preserves its own tint or depth of colour, consequently an admixture of
black and red colours, if red be the colour of the dye used, is present
upon 'or in the fabric.
Hitherto intermixed coloured felted goods have been obtained by the
costly process of dyeing white wool in colours separately, and then
mixing the different dye coloured wools by cardings before the felting
operation is performed, whereas by this Invention we only use one half
more or less of the quantity of white wool and utilize by the admixture
a-black or dark wool, the value of which latter is considerably lower in
the market than any kind of white wool.
Alpaca noils for example by their natural colours afford a great
facility for obtaining the mixtures by the above described process, and
we claim the employment of alpaca noils for the purpose, they not
having been hitherto employed in the manner or for the purpose
intended by this Invention..
According to the second part of our Invention we obtain an effect of
mixed colours in the following manner:-We dye a webbing made of
wool or other material, say for instance black, and then by the effect of
the hardening and felting process Patented by Louis Ferdinand Tavernier,
one of the parties hereto, on the 5th February 1874, No. 466, wo

page_text: produce an implantation of white wool through and into the black
webbing, and obtain a fabric which is, say, white one side and grey on
the other side. If. for instance we dye that fabric in a red colour, one
side of the fabric will be of a plain red colour, and the other side which
was grey a mixture of black and red colours, and so on for any mixtures
of dark and light colours. The fabric thus manufactured and dyed is
reversible, and we intend to call it Victoria Melton. .
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Louis Ferdinand Tavernier and John Pyper
Matheson in the Great Seal Patent Office on the 29th July 1875. .
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, LOUIS
FERDINAND TAVERNIER and JOHN PYPER MATHESON, of the Perseverance
Mills, Dewsbury Road, Leeds, in the County of, York, Patent Coactile
Cloth Manufacturers, send greeting.
WHEREAS Her most- Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of January, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Louis Ferdinand Tavernier and John
Pyper Matheson, Her special licence, that we, the said Louis Ferdinand
Tavernier and John Pyper Matheson, our executors, administrators, and
assigns, or such others as we, the said Louis Ferdinand Tavernier and
John Pyper Matheson, our 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 FELTED FABRICS AND IN
THE PRODUCTION OF MIXED COLOURS IN FELTED FABRICS BY CHEAP AND SIMPLE
PROCESSES," upon the condition (amongst others) that we, the said Louis
Ferdinand Tavernier and John Pyper Matheson, or one of us, our
executors or administrators, by an instrument in writing under our, or
one of our, or their, or one of their hands and seals should particularly
describe and ascertain the nature of the said Invention, and in what

page_text: 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 we, the said Louis Ferdinand Tavernier and
John Pyper Matheson, do hereby declare the nature of our said Inven-
tion, and in what manner the same is to be performed, to be par-
ticularly described and ascèrtained in and by the following statement
thereof, that is to say :——
The objects of this Invention are improvements in the manufacture of
felted fabrics, and in the production of mixed colours in felted fabrics by
cheap and simple processes.
'
We combine natural dark coloured wool or a dark dyed coloured wool
with a natural light colour wool, and mix the two intimately by the
carding process. The wools in the mixed state are then felted in the
ordinary manner upon a cotton or other web or length, and then dyed
in any suitable colour. The natural light colour wool partakes of the-
'dye colour, and the natural dark colour or dark dyed coloured wool.
remains dark. The results is to the eye a mottled or a mixed colour
appearance.
The dye colour can be of any degree of brightness, say of red, brown,
blue, green, or other, which the natural light colour wool, say white,
will become stained or dyed by, but the natural dark or dark dyed colour
wool, say black, being the deeper or stronger of the two colours, preserves
its own tint or depth of colour, consequently an admixture of black and
red colours, if red be the colour of the dye used, is present upon or in
the fabric.
Hitherto intermixed coloured felted goods have been obtained by the
costly process of dyeing white wool in colours separately, and then
mixing the different dye coloured wools by cardings before the felting
operation is performed, whereas by this Invention we only use one half

by this Invention.
According to the second part of our Invention we obtain an effect of
mixed colours in the following manner :-We dye a webbing made of
wool or other material, say for instance black, and then by the effect of.
the hardening and felting process Patented by Louis Ferdinand.
Tavernier, one of the parties hereto, on the 5th February 1874, No. 466,
we produce an implantation of white wool through and into the black
webbing, and obtain a fabric which is, say, white one side and grey on
the other side. If for instance we dye this fabric in a red colour, one
side of the fabric will be of a plain red colour, and the other side which
was grey a mixture of black and red colours, and so on for any mixture
of dark and light colours. The fabric thus manufactured and dyed is
reversible, and we intend to call it Victoria Melton.
In witness whereof, we, the said Louis Ferdinand Tavernier and
John Pyper Matheson, have hercunto set our hands and seals,
this Twenty-seventh day of July, One thousand eight hundred
and seventy-five.
