PROVISIONAL SPECIFICATION.
The Manufacture or Production of Linen and Cotton Goods, or Mixed
Linen and Cotton Goods, with Transparent Designs or Patterns
Woven therein.
I, BENJAMIN JOHN WOLFF, of 14 Bow Lane, in the City of London, Commission
Agent, and Merchant, do hereby declare the nature of this Invention to be as
follows:-
In linen and cotton goods, such for instance as damasks, as at present manufactured,
the design or pattern is only visible when the goods are so placed as to allow the
light to fall on them, but become invisible directly such goods are held up to the
light, thereby rendering the goods unsuitable for many purposes to which they
might be advantageously applied. Now the object of this Invention is to manu-
facture or produce linen or cotton, or mixed linen and cotton goods, in which the
designs or patterns shall be transparent when the goods are held up to the light,
thereby considerably enhancing the value of such goods and rendering them suitable
to a variety of purposes, as for instance to window Blinds.
·
In manufacturing or producing such goods, say damasks, the warp is formed of
40 twist cotton and comprises 4200 threads in 54 inches. The weft, in which the
transparent design or pattern is produced, comprises 64 linen threads to the inch,
and 40 linen yarns, slightly dyed in any suitable colour, preference being given
to yellow.
These goods are made, by preference, on what is known as a 1300 Vincenzi
Jacquard loom, and after leaving the same are soaked in water as pure as possible,
thus causing the design or pattern to stand out in bold relief when held, or placed, to
the light.
In applying the Invention to linen goods both the warp and the weft are made of
linen threads, and the treatment is the same as that above described with reference to
damasks.
Also in manufacturing goods composed of all cotton, both the warp and the weft
are made of all cotton threads or yarn and the same treatment here holds good as for
damasks.
COMPLETE SPECIFICATION.
The Manufacture or Production of Linen and Cotton Goods, or Mixed
Linen and Cotton Goods, with Transparent Designs or Patterns
Woven therein.
I, BENJAMIN JOHN WOLFF, of 14 Bow Lane, in the City of London, Commission
Agent and Merchant, do hereby declare the nature of this 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 :-
In linen and cotton goods, or mixed linen and cotton goods, as at present manu-
factured, the design or pattern is only visible when the goods are so placed as to
allow the light to fall on them, that is to say, by reflected light, such design becoming
invisible when the goods are held up to the light, thereby rendering the same
unsuitable for many purposes to which they might be advantageously applied. Now
the object of this invention is to manufacture or produce such goods in which the
design or pattern shall be transparent and rendered visible when held up to the light,
27

for a variety of purposes, and more particularly for use as window blinds.
In carrying out the invention the warp and weft threads forming the texture of
such goods are so proportioned the one to the other that one of them is composed of a
heavier yarn than the other, whereby the design or pattern produced by the lighter
of such yarns becomes transparent and allows the design to become visible when the
goods are held up to the light.
The proportions of the yarns composing the goods will depend upon the quality and
nature of the goods to be produced. For goods of medium quality composed of
cotton and linen, the following proportions will be found suitable: The warp is
formed of 40 twist cotton and comprises 4200 threads in 54 inches (77.7 threads to
the inch). The weft is formed of 40 twist linen yarn and comprises 64 threads to the
inch, which latter may, if desirable, be slightly dyed.
The goods are made by preference on what is known as a 1300 Vincerzi Jacquard
Loom, and after leaving the same are soaked in water, as pure as possible, so as to
thoroughly cleanse the fabric and thus cause the design or pattern to be clearly seen
when the goods are in use. When made of all cotton the goods may afterwards he
dyed to any desired shade.
It is to be clearly understood that the above mentioned proportions of yarns, as
well as the nature of the material composing the same, may be varied to suit the
requirements of the quality of goods to be produced. For instance the goods may be
composed wholly of linen or wholly of cotton. It is only necessary that either the
warp or weft shall be composed of a lighter yarn than the other.
Having now particularly described and ascertained the nature of my invention, and
in what manner the same is to be performed, I claim :
The manufacture or production of linen and cotton goods, or mixed linen and
cotton goods, in which either the warp or the weft is composed of a lighter yarn than
the other, whereby the design or pattern produced on such goods is rendered
transparent and becomes visible when the same are in use, thereby rendering said
goods specially suitable for window blinds, substantially as herein described.
